In Edge Computing deployment, an application service may be served by multiple Edge Application Servers typically deployed in different sites. These multiple Edge Application Servers that host service may use a single IP address (anycast address) or different IP addresses. To start such a service, the UE needs to know the IP address(es) of the Application Server(s) serving the service. The UE may do a discovery to get the IP address(es) of a suitable Edge Application Server (e.g. the closest one), so that the traffic can be locally routed to the Edge Application Server and service latency, traffic routing path and user service experience can be optimized.

6.2.3.2 Procedure of EAS discovery considering renewable energy information
The procedure listed here are based on the procedure defined in section 8.5.2.2 of 3GPP TS 23.558 [8].
eb1343f2cdb3d270d65fac7ddb0d0638
23.700-44
8.5.2.2 Request-response model
Pre-conditions: 1. The EEC has received information (e.g. URI, IP address) related to the EES; 2. The EEC has received appropriate security credentials authorizing it to communicate with the EES as specified in clause 8.11; and 3. The EES is configured with ECSP's policy for EAS discovery. NOTE 1: Details of ECSP's policy are out of scope. Figure 8.5.2.2-1: EAS Discovery procedure 1. The EEC sends an EAS discovery request to the EES. The EAS discovery request includes the requestor identifier [EECID] along with the security credentials and may include EAS discovery filters, EEC service continuity support, and may also include UE location to retrieve information about particular EAS(s) or a category of EASs, e.g. gaming applications, or Edge Applications Server(s) available in certain service areas, e.g. available on a UE's predicted or expected route. The request may include an EAS selection request indicator. If an e2e tunnel is used in the UE for applications (e.g. user configured tunnel service), and if the tunnel service provider and the ECSP are from the same organization and only if user grants the permission, then the EEC provides the tunnel information for the associated applications in the request to the EES considering user consent. The EAS discovery filter may include energy requirements to the EAS, e.g., Energy mode, Energy type supports. The Energy type is about requirement to the EAS on its supported energy type (e.g. non-renewable energy and/or renewable energy). NOTE 2: The e2e tunnel case is limited to case where the tunnel service is deployed in home domain in the present release. 2. Upon receiving the request from the EEC, the EES checks if the EEC is authorized to discover the requested EAS(s). The authorization check may apply to an individual EAS, a category of EASs or to the EDN, i.e. to all the EASs. If EAS discovery filters contain energy requirements, the EES checks whether the EAS satisfy the requirements on Energy type supports in the EAS discovery requests. If the EAS fulfil the energy requirements, then EES adds the identified EAS(s) into the list of discovered EAS(s). If UE's location information is not already available, the EES obtains the UE location by utilizing the capabilities of the 3GPP core network as specified in clause 8.10.3. If EAS discovery filters are provided by the EEC, but it does not contain Application group profile, the EES identifies the EAS(s) based on the provided EAS discovery filters and the UE location. For the identified EAS(s) if EAS profile indicates the list of associated devices required in order to serve the UE, then EES checks whether the UE has required associated devices with it or not based on AC profile received in EAS discovery request. If the UE has the required associated devices then EES adds the identified EAS(s) into the list of discovered EAS(s). When the bundle EAS information is provided, then - If bundle EAS information includes EAS bundle identifier, the EES identifies all or part of the EAS(s) associated with the same EAS bundle identifier. - If bundle EAS information includes a list of EASIDs, the EES identifies the EASs which are all or part of the EAS bundle. If the EEC indicates that service continuity support is required, when identifying the EAS, the EES shall take the indication which ACR scenarios are supported by the AC, the EEC, the EES and the EAS and which of these are preferred by the AC into consideration. The EES may select one EAS and determine whether to perform application traffic influence for this EAS in advance based on AC's service KPI or EAS’s service KPI in desired response time, when the EAS does not perform traffic influence in advance. If the EES determines to perform application traffic influence for this EAS in advance, then the EES will applies the AF traffic influence of the EAS in the 3GPP Core Network before sending EAS discovery response. If the Prediction expiration time is provided then the EES may determine whether to identify the instantiable but not instantiated EAS as T-EAS based on Prediction expiration time and the predicted EAS deployment time information obtained from ADAES as specified in clause 8.11 of TS 23.436 [28] or from local configured maximum EAS deployment time. The EES determines remaining EAS instantiation time or EAS instantiation completion time based on the timing receiving EAS instantiation is in progress from ECSP management system and the predicted EAS deployment time. Furthermore, if EES received the indication which the EAS instantiation is in progress, then the EES determines whether to identify the EAS which instantiation in progress as T-EAS based on Prediction expiration time and remaining EAS instantiation time information. When EAS discovery filters are not provided, then: - if available, the EES identifies the EAS(s) based on the UE-specific service information at the EES and the UE location; - EES identifies the EAS(s) by applying the ECSP policy (e.g. based only on the UE location), When EAS discovery filters contain Application group profile, the EES checks whether information about common EAS and related Application Group ID is available or not. If the common EAS information related to the Application Group ID is: - not available at the EES, then based on the policy if EES needs to select the common EAS, the EES identifies an EAS for the Application Group ID based on the provided EAS discovery filters such as KPIs, UE-specific service information or the ECSP policy. Furthermore, the EES stores the common EAS information and related Application Group ID. The EES may also subscribe and get the notifications of candidate DNAIs for the UEs of the group as described in 3GPP TS 23.548 [20], 3GPP TS 23.501 [2], the EES identifies the EAS(s) taking the candidate DNAIs into account, e.g., an EAS where its DNAI in the EAS profile is common to all UEs in the group. - available at the EES, then the EES provides information of that EAS as result for EAS discovery, or the EES identifies the EAS based on the provided EAS discovery filters and the UE location when E2E response time is received, furthermore: - when the UE in the overlapping area between the EDNs of common EAS and EAS registered to this EES (e.g. UE can connect either common EAS or EAS registered to this EES which is UE is in the common EAS service area), the EES identifies either common EAS or EAS registered to this EES for the UE based on the UE location, EAS discovery filters, application group profile, common EAS KPI as specified in table 8.2.5 and EDN information, registered EAS KPI as specified in table 8.2.5 and EDN information, and inter-EAS communication performance of these EASs and checks whether the common EAS or EAS registered to this EES can provide better E2E response time. - When the UE is not in the overlapping area between the EDNs of common EAS and EAS registered to this EES (e.g. UE is not in the common EAS service area), then the EES identifies candidate EAS(s) for the group from its registered EASs based on UE location, EAS discovery filters and application group profile and checks if the candidate EAS(s) can satisfy the E2E response time considering the response time of the candidate EAS(s), the response time of available common EASs in other EDNs and the inter-EAS communication latency. If the E2E response time cannot be satisfied, the EES will respond the EEC in step 3 indicating such a rejection reason; otherwise, the EES selects a candidate EAS and interacts with the ECS-ER to store it as common EAS as described in clause 8.20.2.3. NOTE 3: The EES can use ADAE analytics service in 3GPP TS 23.436 [28] or local configuration to obtain application performance (e.g. latency) for inter-EAS communication. NOTE 4: If the current EDN has overlapping area (where UE resides) with other EDN and both EDNs has available common EAS which can satisfy E2E response time, which EAS to select can take number of UEs in the group connected to available common EAS into consideration. NOTE 5: The EES may have previously determined and stored the common EAS for Application group ID, or the EES may have received the common EAS selection information for Application group ID during the common EAS announcement procedure. When the ECS-ER is not available and the EES selects the common EAS, the selected common EAS shall be announced to other EES(s) as per procedure specified in clause 8.19. When the ECS-ER is available, if the common EAS information related to the Application Group ID is: - not available at the ECS-ER, the EES identifies one EAS for the group and interacts with the ECS-ER to store the common EAS information as described in clause 8.20.2.3. The EES may also subscribe and get the notifications of candidate DNAIs for the UEs of the group as described in 3GPP TS 23.548 [20], 3GPP TS 23.501 [2], the EES identifies the EAS(s) taking the candidate DNAIs into account, e.g., an EAS where DNAI in the EAS profile is common to all UEs in the group. - available at the ECS-ER, then the ECS-ER returns the common EAS information to the EES as described in clause 8.20.2.3, or the EES identifies the EAS based on the provided EAS discovery filters and the UE location when E2E response time is received, furthermore: - When the UE is in the overlapping area between the EDNs of common EAS and EAS registered to this EES (e.g. UE can connect either common EAS or EAS registered to this EES, which is UE is in the common EAS service area), the EES identifies either common EAS or EAS registered to this EES for the UE based on the UE location, EAS discovery filters, application group profile, common EAS KPI as specified in table 8.2.5 and EDN information, registered EAS KPI as specified in table 8.2.5 and EDN information, and inter-EAS communication performance of these EASs and checks whether the common EAS or EAS registered to this EES can provide better E2E response time. - When the UE is not in the overlapping area between the EDNs of common EAS and EAS registered to this EES (e.g. UE is not in the common EAS service area), the EES checks with the ECS-ER about all available common EASs and their corresponding EDNs by using procedure defined in clause 8.20.2.2. If no common EAS is available for the group, EES identifies one EAS for the group and interacts with the ECS-ER to store the common EAS information as described in clause 8.20.2.3. If current EDN already has available common EAS, the EES selects such common EAS considering UE location, EAS discovery filters, application group profile and the required E2E response time. If there are available common EASs in other EDNs, the EES identifies candidate EAS(s) for the group from its registered EASs and checks if the candidate EAS(s) can satisfy the E2E response time considering UE location, EAS discovery filters, application group profile, and the response time of the candidate EAS(s), the response time of available common EASs in other EDNs and the inter-EAS communication latency. If the E2E response time cannot be satisfied, the EES will respond the EEC in step 3 indicating such a rejection reason; otherwise, the EES selects a candidate EAS and interacts with the ECS-ER to store it as common EAS as described in clause 8.20.2.3. NOTE 6: The EES can use ADAE analytics service in 3GPP TS 23.436 [28] or local configuration to obtain application performance (e.g. latency) for inter-EAS communication. NOTE 7: Details of the UE-specific service information and how it is available at the EES is out of scope. NOTE 8: Both steps are evaluated prior to sending a response. Upon receiving the request from the EEC, the EES may also collect edge load analytics from ADAES (as specified in clause 8.8.2 of TS 23.436 [28]) or performance data from OAM to find whether the EAS(s) satisfies the Expected AC service KPIs or the Minimum required AC Service KPIs. Upon receiving the request from the EEC, if the EEC does not indicate EAS Instantiation Triggering Suppress in the EAS Discovery request, the EES may trigger the ECSP management system to instantiate the EAS that matches with EAS discovery filter IEs (e.g. ACID) as in clause 8.12. Otherwise, upon receiving the request from the EEC, if the EEC indicates EAS Instantiation Triggering Suppress in the EAS Discovery request and the EES supports such capability, the EES determines not triggering the ECSP management system to instantiate the EAS and may determine Instantiable EAS Information for EAS(s) that are instantiable but not yet instantiated and match the EAS discovery filter IEs. Instantiable EAS Information is provided in the EAS Discovery response and includes the EASID(s) and, for each EASID, the status indicating whether the EAS is instantiated or instantiable but not yet instantiated. If the EEC provides in the EAS discovery request the EAS selection request indicator, the EES selects EAS satisfying the EAS discovery filter or based on other information (e.g. ECSP policy) as described above (if no EAS discovery filter received), and then provides the selected EAS information to the EEC in the discovered EAS list of EAS discovery response. NOTE 9: Without EAS selection request indication, the EES handling is as per R17 procedure. If the tunnel information is received, the EES additionally takes it into consideration in identifying EAS(s). If no tunnel information is received, the EES additionally takes the N6 tunnel (e.g. L2TP) information from 3GPP core network (via NEF user plane path management service as described in 3GPP TS 23.501 [2], clause 5.6.7) or NATed UE IP address (e.g. by local UPF based on local configuration) and EAS IP address information into consideration in identifying EAS(s). For instance, the IP address(es) of identified EAS(s) needs to be topologically close to the IP address of the tunnel server, local UPF (based on NATed UE IP address) or NATed UE for optimal N6 route. 3. If the processing of the request was successful, the EES sends an EAS discovery response to the EEC, which includes information about the discovered EASs and Instantiable EAS Information. For discovered EASs, this includes endpoint information. If the EES perform traffic influence for EAS(s) in step 2, then the discovered EAS(s) is with optimized traffic route. Depending on the EAS discovery filters received in the EAS discovery request, the response may include additional information regarding matched capabilities, e.g. service permissions levels, KPIs, AC locations(s) that the EASs can support, ACR scenarios supported by the EAS, etc., and regarding satisfied energy requirements, e.g., supported energy type. The EAS discovery response may contain a list of EASs and Instantiable EAS Information with EAS instantiation completion time. This list may be based on EAS discovery filters containing a Geographical or Topological Service Area, e.g. a route, included in the EAS discovery request by the EEC. When the discovered EAS is for a certain application group, then the Application Group ID is also included in the response message. If the discovered EAS is registered to another EES, then the EES endpoint of the EES where the discovered EAS is registered is also included in the response message. When the EES accepts the request and determines to trigger the EAS instantiation, then the response may indicate that the EAS instantiation is in progress so that the detailed EAS profile information will be available later. Then the EES determines the remaining EAS instantiation time or EAS instantiation completion time based on the timing receiving EAS instantiation in progress ECSP management system and the predicted EAS deployment time. When EEC receives the EAS instantiation in progress indication, the EEC may send EAS discovery subscription request message if not subscribed yet or send EAS discovery request message later to the EES for obtaining updated EAS information. If the EES is unable to determine the EAS information using the inputs in the EAS discovery request, UE-specific service information at the EES or the ECSP policy, the EES shall reject the EAS discovery request and respond with an appropriate failure cause. If the EEC is not registered with the EES, and ECSP policy requires the EEC to perform EEC registration prior to EAS discovery, the EES shall include an appropriate failure cause in the EAS discovery response indicating that EEC registration is required. If the UE location and predicted/expected UE locations, provided in the EAS discovery request, are outside the Geographical or Topological Service Area of an EAS, then the EES shall not include that EAS in the discovery response. The discovery response may include EAS(s) that cannot serve the UE at its current location if a predicted/expected UE location was provided in the EAS discovery request. Upon receiving the EAS discovery response, if the EEC selects an EAS which is instantiated (i.e., an EAS profile was provided), the EEC uses the endpoint information for routing of the outgoing application data traffic to EAS(s), as needed, and may provide necessary notifications to the AC(s). The EEC may use the border or overlap between EAS Geographical Service Areas for service continuity purposes. The EEC may cache the EAS information (e.g. EAS endpoint) for subsequent use and avoid the need to repeat step 1. If the Lifetime IE is included in the response, the EEC may cache the EAS information only for the duration specified by the Lifetime IE. Upon receiving the EAS discovery response, if the EEC selects an EAS which is instantiable but not yet instantiated (i.e. an EAS profile is not provided), the EEC sends the EAS information provisioning request indicating the selected EASID as in clause 8.15. If the EAS discovery response message contains the EAS(s) information along with r EAS instantiation completion time which the EAS instantiation in progress, then the EEC determines whether to identify the EAS which instantiation in progress as T-EAS based on Prediction expiration time and remaining EAS instantiation time/EAS instantiation completion time. If the EEC determines to identify the EAS for which instantiation is in-progress, the EEC may retry to discover the EAS and send the EAS discovery request again after waiting for the time as included in the response message, otherwise, the EAS discovery may fail. NOTE 10: Within the duration specified by the Lifetime IE, the cached EAS Profile can be updated (e.g. according to notifications from the EES for changes of EAS information due to EAS status change) or the cached EAS Profile can be invalidated due to new EAS information discovery (e.g. due to UE mobility). The EEC can update or invalidate the cached EAS information (e.g. on PDU Session Release or Modification Command). NOTE 11: The AC can cache the EAS information (e.g. EAS endpoint) for subsequent use. In the case of the cached information needing to be updated or invalidated, the mechanisms for the EEC to notify the AC is up to implementation and is not specified in the current release of the present document. NOTE 12: The EEC can use the EAS information provided by the discovery procedure to perform service continuity planning, for example when ultra-low latency ACR is required. If the EAS discovery request fails, the EEC may resend the EAS discovery request, taking into account the received failure cause. If the failure cause indicated that EEC registration is required, the EEC shall perform an EEC registration before resending the EAS discovery request. NOTE 13: As long as a proper EAS (e.g. considering expected AC service KPIs included in EAS discovery request) is discovered and selected by the EES, EEC of a constraint UE can stop sending EAS discovery to rest candidate EES(s), and provide the selected EAS information to AC. The information flow for EAS discovery as specified in clause 8.5.3.2 of 3GPP TS 23.558 [aa8] is enhanced as follows (new text in bold italics):

If the requestor is authorized, the AIMLE server performs AIMLE client selection based on the provided inputs as described below. For VAL server selection, the AIMLE server receives a list of AIMLE client IDs in the request and selects the AIMLE clients in the list as candidate AIMLE clients. For AIMLE server selection, the AIMLE server retrieves a list of clients with AI/ML capabilities from the ML repository. From the list of clients, the AIMLE server selects a list of candidate AIMLE clients, whose client profiles fulfil the AIMLE client selection criteria. The AIMLE server may use SEAL (LM service), NEF (e.g. MonitoringEvent API), and NWDAF (e.g. UE mobility analytics as defined in clause 6.7.2 of 3GPP TS 23.288 [2]) capabilities to assist the AIMLE client selection. The AIMLE server determines UEs by using their identifiers to determine their location and then selects only those that fulfil the location requirements specified in the AIMLE client selection criteria. The AIMLE server may use SEAL-LMS (as in 3GPP TS 23.434 [5] clause 9.3.9, or 3GPP TS 23.434 [5] clause 9.3.10) or 3GPP 5G Core Network Services (such as GMLC as in 3GPP TS 23.273 [13] and NEF as in 3GPP TS 23.273 [13] or 3GPP TS 23.502 [9]) to determine the UEs which fulfil the location requirement. The AIMLE server may then determine the QoS parameters for the AIML traffic session between the requestor and the candidate AIMLE client(s) and configure the AI/ML traffic session(s) via SEALDD (Sdd_RegularTransmission API) or NEF services (AfSessionWithQoS API). The AIMLE server determines the application QoS parameters based on the VAL Service ID. NOTE 1: To determine the application QoS parameters based on the VAL service ID, the AIMLE server can use the VAL service ID associated AIMLE client QoS requirements in the AIMLE client selection criteria provided in step 1. If the AIMLE client selection criteria include energy consumption requirements, the AIMLE server retrieves a list of ML model information from the ML repository using the ML model information discovery procedure as described in clause 8.11.3. The AIMLE server uses information from the AIMLE client selection criteria as filtering criteria for ML model information discovery. If energy consumption requirements are included, the AIMLE server selects the candidate AIMLE clients that fulfil the expected energy consumption needs for the retrieved ML models. The expected energy consumption needs are based on the requested AI/ML operations and on the AIMLE client’s power profile. If the energy consumption requirements include a maximum energy budget, the AIMLE server identifies and selects the ML models and candidate AIMLE clients that can perform the requested AI/ML operations without exceeding the maximum energy budget. NOTE 2: If the available AIMLE clients (as determined by the AIMLE server) that fulfil discovery criteria are less than the required number of AIMLE clients for AI/ML operation (e.g., split AI/ML), then the AIMLE server can discover the remaining required AIMLE clients from other AIMLE servers over AIML-E reference point and include them in the AIMLE client selection response message. NOTE 3: The AIMLE server can reuse SEAL group management for any necessary group management. 4. The AIMLE server performs AIMLE client participation procedure with each candidate AIMLE client as described in clause 8.10. For all candidate AIMLE clients that agreed to participate in AI/ML operations, the AIMLE server selects the AIMLE clients and assigns an AIMLE client set identifier for the selected clients. The AIMLE client set may then be used for training a ML model. NOTE 4: If a required minimum number of AIMLE clients for AI/ML operation is provided in the AIMLE client selection request and the number of AIMLE clients that agreed to participate in AI/ML operations is less than this number, an AIMLE client set identifier will not be assigned and the status will be set to fail in the AIMLE client selection response in step 5. 5. The AIMLE server sends an AIMLE client selection response that includes information in Table 8.9.3.2-1. 6.x4.1.5 Impact to AIMLE client selection subscription The AIMLE client selection subscription procedure and information flows in 3GPP TS 23.482 [r2348210] are enhanced (highlighted in bold italics) as follows.

8.13.2.2 AIMLE client selection subscription and notification
Figure 8.13.2.2-1: AIMLE client selection subscription and notification 1. A VAL server sends an AIMLE client selection subscription request to the AIMLE Server. The AIMLE client selection subscription request includes information as described in Table 8.13.3-1 which includes selection criteria. 2. The AIMLE server validates the AIMLE client selection subscription request. The AIMLE server further performs authentication and authorization checks to determine if the requestor is able to subscribe to the selected AIMLE client selection subscription request. 3. The AIMLE server sends the AIMLE client selection subscription response to the VAL server. 4. The AIMLE server monitors AIMLE clients whether they fulfil the selection criteria as provided in step 1. The AIMLE server interacts with the NEF and/or SEAL services (including SEALDD) to establish monitoring. The AIMLE server utilizes SEAL-LMS (as in 3GPP TS 23.434 [5] clause 9.3.11, or 3GPP TS 23.434 [5] clause 9.3.12) or 3GPP 5G Core Network Services (such as GMLC as in 3GPP TS 23.273 [13] and NEF as in 3GPP TS 23.273 [13] or 3GPP TS 23.502 [9]) to establish monitoring of UEs entering or present in the target location provided in the location information in the selection criteria. 5. The AIMLE Server obtains the identifiers of the AIMLE clients from the monitoring and selects the clients that fulfil the selection criteria and remove the AIMLE clients which do not fulfil the selection criteria. The AIMLE server uses the location monitoring for selecting UEs that fulfil the location criteria and removing UEs which cease to fulfil the location criteria as provided in the location information in the AIMLE client selection criteria. The AIMLE Server may determine the application QoS parameters (e.g. bandwidth, latency, jitter) for the AIML traffic session between the VAL server and the selected AIMLE client and configure the AIML traffic session(s) via SEALDD (Sdd_RegularTransmission API) or NEF services (AfSessionWithQoS API). When the AIMLE clients no more meet the criteria, the QoS adjustment is reversed. The AIMLE server may determine the application QoS parameters based on the VAL Service ID. If the AIMLE client selection criteria include energy consumption requirements, the AIMLE server retrieves a list of ML model information from the ML repository using the ML model information discovery procedure as described in clause 8.11.3. The AIMLE server uses information from the AIMLE client selection criteria as filtering criteria for ML model information discovery. If energy consumption requirements are included, the AIMLE server selects the candidate AIMLE clients that can fulfil the expected energy consumption needs of the ML model. The expected energy consumption needs are based on the requested AI/ML operations and on the AIMLE client’s power profile. If the energy consumption requirements include a maximum energy budget, the AIMLE server identifies and selects the ML models and candidate AIMLE clients that can perform the requested AI/ML operations without exceeding the maximum energy budget. If a desired service in the selection criteria is ceased to be provided by the client or its profile change so that it no longer meets the selection criteria, the AIMLE server removes the AIMLE clients which ceases to fulfil the criteria and selects other clients that fulfil selection criteria. NOTE 1: To determine the application QoS parameters based on the VAL service ID, the AIMLE server can use the VAL service ID associated AIMLE client QoS requirements in the AIMLE client selection criteria provided in step 1. NOTE 2: In case of AIMLE server determining the application QoS parameters based on the VAL service ID, how it does this is up to implementation. 6. The AIMLE Server notifies the VAL server about the selected and re-selected AIMLE clients e.g., the AIMLE Client A is re-selected and replaced by AIMLE Client B. 6.x4.1.6 Impact to AIMLE client participation The AIMLE client participation procedure and information flows in 3GPP TS 23.482 [r2348210] are enhanced (highlighted in bold italics) as follows.

As indicated in 3GPP TS  28.310 [4], the renewable energy and renewable energy factor have the following definitions: Renewable energy: energy from renewable non-fossil sources. NOTE 15: This definition is taken from 3GPP TS 22.261 [31]. NOTE 16: Examples of renewable energy sources include wind, solar, aerothermal, geothermal, hydrothermal and ocean energy, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases NOTE 17: A renewable energy source is an energy source not depleted by extraction as it is naturally replenished at a rate faster than it is extracted ISO/IEC 30134-3:2016 [33]. NOTE 18: Criteria to categorize an energy as renewable can differ among jurisdictions, based on local environmental or other reasons ISO/IEC 30134-3:2016 [33]. Renewable energy factor: ratio of the renewable energy to the total energy. NOTE 19: This definition is taken from ISO/IEC 30134-3:2016 [33]. Energy can be classified into two major types: renewable energy and non-renewable energy. Renewable energy sources include solar energy, hydropower, wind energy, biomass energy, wave energy, tidal energy, ocean thermal energy, geothermal energy, etc. They can be recycled and regenerated in nature. It is an inexhaustible and endless energy source that regenerates automatically without human intervention. In order to save the energy consumption and reduce the carbon emission, the operators may consider using renewable energy or green energy to replace traditional energy. So, in the current AIMLE procedure, the following enhancements can be added: For AIMLE related procedure: - The FL member capabilities can include whether renewable energy support or not. It is more preferred to select the FL members that support renewable energy to perform such as AI model training. This capability can be indicated during the registration procedure. - Also, the capability that support renewable energy can be set as the Member selection criteria.

8.4.2 Procedure on FL member registration
Figure 8.4.2-1 illustrates the procedure where the registration of a candidate FL member happens via the ML repository, serving as AIML service registry. Figure 8.4.2-1: Procedure for registration on FL member registry 1. The candidate FL member (e.g., VAL server via AIMLE server or AIMLE server) sends an FL member registration request to the ML repository for registering to the ML repository which acts as the AIML service registry. The request may include capability whether this FL member supports the renewable energy as energy supply or not. Editor’s Nnote: How does FL member knows the capability of renewable energy supporting is FFS. 2. The ML repository validates the received request and generates the identity and other security related information for all the FL members listed in the registration request. 3. The ML repository sends the generated information in the FL member registration response message to the candidate FL member. The procedure for AIMLE client to register to ML repository as FL member is introduced in clause 8.7.2.2. 6.x5.3.2 Procedure of FL-related event subscription of renewable energy This procedure is the same as the procedure in section  8.5.2 of 3GPP TS  23.482 [x10] with the following enhancement:

8.5.2 Procedure on subscription for FL related events
This procedure, as illustrated in Figure 8.5.2-1, describes the subscription for events related to FL member availability. Pre-conditions: 1. The AIMLE server has the authorization to subscribe for the FL-related events (events described in clause 8.5.4). Figure 8.5.2-1: Procedure for FL-related event subscription 1. The subscriber (AIMLE server or VAL server (via AIMLE server)) sends an FL-related event subscription request to the ML repository to receive notification of FL related events and in particular the availability of FL member for a target area and time. The subscription includes indicator whether the FL member supports the capability of renewable energy supporting or not. 2. Upon receiving the event subscription request from the AIMLE server, the ML repository checks for the relevant authorization for the event subscription. If the authorization is successful, the ML repository stores the subscription information. 3. The ML repository sends an FL-related event subscription response to the subscriber indicating successful operation. 6.x5.3.3 Procedure of member selection during ML model training considering renewable energy This procedure is the same as the procedure in section  8.3.2 of 3GPP TS  23.482 [x10] with the following enhancement:

8.3.2 Procedure for ML model training
Figure 8.3.2-1 illustrates the procedure for AIMLE server to support ML model training based on the request from the VAL server. Figure 8.3.2-1: ML model training 1. The VAL server sends an ML model training request to AIMLE server, requesting to assist in its ML model training. This request consists of ML model information or ML model requirement information, capability of renewable energy supporting or not, etc. 2. The AIMLE server checks whether the VAL server is authorized to perform the ML model training request. If no model information is provided but only the model requirement information is provided in step 1, the AIMLE server identifies and selects the appropriate ML model for training based on the ML model requirement information using the procedure as specified in clause 8.11.3. 3. If the VAL server is authorized, AIMLE server returns the success response, otherwise a failure response indication the reason for failure. 4. The AIMLE server notifies the VAL server to update the list FL/ML clients selected or de-selected for the ML model training or to share the training output or any errors during the training process. 6.x5.4 Solution evaluation Editor’s Nnote: This part is for further update in the future. 6.x6 Solution #x6: Support of ADAE analytics for AI/ML energy consumption 6.x6.1 Solution Description This solution addresses Key Issue #4 – open issue #1 on how to collect and use energy consumption data. The solution proposes a new ADAE service procedure in 3GPP TS 23.436 [r2343611] to support AI/ML energy consumption analytics. 6.x6.1.1 Procedure Figure 6.x6.1.1-1 illustrates the procedure for a consumer (e.g., VAL server, AIMLE server) to subscribe for AI/ML energy consumption analytics generated from data collected from VAL UEs while the VAL UEs are performing AI/ML operations. Pre-conditions: 1. ADAE Client (ADAEC) is connected to the ADAE Server (ADAES). 2. Data producers (e.g., VAL Clients) may be pre-configured with data producer profiles for the data they can provide. ADAES and ADAEC have discovered available data producers and their data producer profiles. Figure 6.x6.1.1-1: ADAES support for AI/ML energy consumption analytics 1. An analytics consumer (e.g. VAL Server, AIMLE Server) sends an AI/ML energy consumption analytics subscription request to an ADAES. The subscription request includes an Analytics ID “AI/ML energy consumption analytics”, ML model identifier, AIML operation, energy consumption metrics, and other information as defined in Table 6.x6.1.2.1-1. 2. The ADAES validates the subscription request and performs authentication and authorization checks to determine if the consumer is authorized to subscribe for the requested analytics. If authorization is successful, the ADAES stores the subscription request information, assigns a subscription ID, and sends a subscription response indicating successful subscription and includes the subscription ID. 3. The ADAES maps the analytics ID to a list of data collection event identifiers and determines a list of data producer IDs for the data collection event identifiers. The determination of data producer IDs is based on data producer profiles. 4. The ADAES sends an AI/ML energy consumption data collection subscription request to the ADAECs determined in step  3. The subscription request includes information as defined in Table 6.x6.1.2.4-1. Data collection at the VAL UE(s) reuses the EVEX mechanism defined in 3GPP TS 26.531 [r2653112]. 5. Each ADAEC configures the data producers (i.e., VAL client or AIMLE client) for collecting data (e.g., duration of AI/ML operation, % resource utilization for AI/ML operation) for AI/ML energy consumption analytics requested in the data collection subscription request. 6. The ADAEC sends an AI/ML energy consumption data collection subscription response to acknowledge the ADAES. The response includes a status and a subscription ID for the data collection. 7. The data producers perform AI/ML operations when triggered (e.g., ML model training) using the indicated ML model and collect data for AI/ML energy consumption analytics based on the configured data collection requirements. 8. At the completion of AI/ML operation, the ADAEC sends an AI/ML energy consumption data collection notification to the ADAES. The data notification includes the data collection subscription ID and the information as defined in Table 6.x6.1.2.6-1. 9. The ADAES performs analytics relevant operations to generate the AI/ML energy consumption analytics based on the data received from the ADAECs. The ADAES uses the data collected by the ADAECs to calculate the AI/ML energy consumption analytics. NOTE: How the collected data are used to calculate energy consumption is up to implementation. 10. The ADAES sends an AI/ML energy consumption analytics notification to the consumer. The analytics notification includes the analytics subscription ID and the information as defined in Table 6.x6.1.2.3-1. 6.x6.1.2 Information flows 6.x6.1.2.1 AI/ML energy consumption analytics subscription request Table 6.x6.1.2.1-1 describes the information flow from the consumer (e.g. VAL server, AIMLE server) as a request or update request for AI/ML energy consumption analytics.

These analytics may be used for predicting whether an AI/ML client at the VAL UE can be considered a candidate in a ML training or inference task, or FL process based on its expected energy status/capability. Such energy analytics can be used for identifying whether the energy consumption is sustainable for a given AIMLE service, or a recommendation on whether the AIMLE client is applicable or suitable for the AI/ML task based on the energy prediction or sustainability indicator. This clause describes the procedure for supporting the AIMLE client energy analytics in ADAES as new analytics service. • Figure 6.x7.1-1: ADAES support for AIMLE client energy analytics 1. The Consumer (AIMLE or VAL server) sends an AIMLE client energy sustainability analytics request to ADAES to perform analytics on the AIMLE client Energy Consumption who is expected to undertake an AIML task, Event ID= “AIMLE client energy sustainability analytics”, for a given service area and a given time window. This request includes a VAL service ID or AIMLE service ID for which the analytics apply, as well as the consumer identifier and the analytics KPI. Such request can include a predicted or expected route of the VAL UE hosting the AIMLE client, and the type of analytics requested. The analytics type can be requesting whether the energy consumption is sustainable for a given AIMLE service. Such request can also include an AI/ML task or operation or process (ML training or inference or FL task) for which the prediction/stats apply. 2. The ADAES authorizes the consumer’s request. 3. The ADAES maps the AIMLE client energy analytics event ID to a list of data collection event identifiers, and a list of data producer IDs. Such mapping may be preconfigured by OAM or may be determined by ADAES based on the analytics event type/vertical type and/or data producer profile. ADAES determines and maps the analytics event to the energy data to acquire and the data producers which can be functionalities in the target VAL UE(s) and/or data stored in A-ADRF. Optionally, the ADAES (or A-ADRF) keeps per AIMLE client. This energy profile keeps stats or energy rating of the AIMLE client or the data source in the UE (e.g. AI app) which can be used as a metric to identify whether the AIMLE client at the VAL UE is energy demanding source; hence applicable or not to be considered as capable of undertaking an AI/ML task. NOTE: If Energy Profile is used, this information may either be provided by the VAL UE (or the VAL server) as part of the energy data or can be quantified at the ADAES. 4a. The ADAES requests and receives from the VAL UE(s) of interest energy data using the AIMLE client Energy Data Collection API. Such Energy data collection can include measurements or stats on the energy consumption per AIMLE client. Editor’s Note: Further details on the energy data collection from the VAL UE is FFS. 4b. In addition, or complementary to AIMLE client energy data collection, the ADAES may also request and receive from the ADAEC of the UE, performance statistics related to the application layer or enabler layer sessions (based on existing ADAE capabilities on VAL session analytics). 5. The ADAES calculates the expected AIMLE client energy consumption based on the received energy/ performance data in step  4, based on the request. 6. The ADAES obtains the corresponding trained ML model based on procedure in 3GPP TS 23.482 [10] clause 8.3.2 and performs analytics to derive the predicted UE energy consumption sustainability at the target area and time horizon. 7. The ADAES sends the analytics output via the AIMLE client energy sustainability analytics API to the consumer (VAL or AIMLE server) as analytics response with the analytics output data (based on the type of analytics in the request). The analytics output may include: • identification on whether the energy consumption is sustainable for a given VAL or AIMLE service, where this service can be an AI/ML service • a recommendation on whether the AIMLE client is applicable or suitable for the AI/ML task based on the energy prediction or sustainability indicator. The ADAES and/or the AIMLE (as consumer) may also store the energy data and/or analytics to a repository being A-ADRF or ML repository (if this applies to an ML task). Based on  step  7, the consumer (AIMLE or VAL server) can use these analytics as input to trigger the pro-active selection or re-selection or removal of the AIMLE client from the list of UEs which are capable of undertaking an AI/ML process/task/operation, given the energy factor. 6.x7.2 Architecture impacts This clause will provide the architecture impacts of the solution and possible new SA6 capabilities and interfaces. 6.x7.3 Solution evaluation This clause will provide an evaluation of the solution.

Instead, it proposes introducing a new VAL server policy in clause 9.5, 'Network slice optimization based on VAL server policy', 3GPP TS 23.435 [zz13]. The new policies enable NSCE server performs slice modifications based on monitoring energy-related information, such as energy consumption and the renewable energy ratio, at the slice level. The high-level principles are as follows: 1. The VAL server provisions energy saving policies to the NSCE server. • Based on the monitored energy consumption of a network slice - categorized by energy source (renewable or non-renewable) - over a specific duration (such as one hour) or as accumulated over a longer period (for example, a calendar month), slice modification is triggered when the measured value exceeds or falls below a defined threshold. This modification may involve reducing the slice's maximum throughput, slightly increasing allowable latency, or decreasing redundancy levels (such as removing a redundant UPF instance or redundant RAN cell). • Based on the monitored renewable energy ratio of a network slice, a slice modification with predefined parameters is triggered when the energy ratio or crosses a specified threshold. Such modifications may include increasing the slice’s maximum throughput, raising allowable latency, expanding the maximum number of supported UEs, or increasing the maximum number of PDU sessions. 2. The NSCE server monitors a slice's energy usage by gathering energy-related data from the slice's OAM system. 3. Based on the defined triggers, the NSCE server carries out the actions outlined in energy-saving policies, aiming to either reduce the slice’s energy consumption or encourage the use of renewable energy sources. The following clauses specify network slice energy optimization based on energy saving VAL server policy. 6.Y18.1.1 Procedure Figure 6.Y18.1.1-1 outlines the procedure, where Steps 1-4 represent existing operations. Step 5 introduces a new function in which the NSCE server monitors energy-related information for a network slice. Step 6 involves the NSCE server taking action to adjust the slice, either to conserve energy or to encourage the use of renewable energy sources. Figure 6.Y18.1.1-1: VAL server policy provision and enforcment for energy optimization 1. The consumer (VAL, SEAL Server) sends a VAL server policy provisioning request to the NSCE server by following clause 9.5 of 3GPP TS 23.435 [zz13]. New energy saving related policies (see examples in clause 6.Y18.1.2) are added: a. Based on the monitored energy consumption of a network slice - categorized by energy source (renewable or non-renewable) - over a specific duration (such as one hour) or as accumulated over a longer period (for example, a calendar month), slice modification is triggered when the measured value exceeds or falls below a defined threshold. This modification may involve reducing the slice's maximum throughput, slightly increasing allowable latency, or decreasing redundancy levels (such as removing a redundant UPF instance or redundant RAN cell). b. Based on the monitored renewable energy ratio of a network slice, a slice modification with predefined parameters is triggered when the energy ratio or crosses a specified threshold. Such modifications may include increasing the slice’s maximum throughput, raising allowable latency, expanding the maximum number of supported UEs, or increasing the maximum number of PDU sessions. The action of the above policy may include charging policy update when slice SLA is modified to save energy to attract the VAL server to use the policies. 2. The NSCE server performs a VAL server policy check. This is the same as step 2 in clause 9.5.2.1, 3GPP TS 23.435 [zz13]. 3. The NSCE server performs Slice Harmonization. This step is the same as clause 9.5.2.1.4 Policy harmonization, 3GPP TS 23.435 [zz13]. 4. The NSCE server sends back a VAL server policy provisioning response to the Consumer (VAL/ASP), confirming policy provision. This is the same as step 2 in clause 9.5.2, 3GPP TS 23.435 [zz13]. 5. The NSCE server initiates the retrieval of energy consumption data from the slice OAM (3GPP  TS  28.554  [6]) to monitor energy-related information, including but not limited to the following parameters: a. slice accumulated energy consumption refers to summing the average energy usage recorded during each slice OAM measurement interval (for example, every 15 minutes) by the OAM system and aggregating it into the total energy consumption over an extended period, such as a calendar month b. slice average energy consumption: e.g. Energy-Consumption/hour c. slice renewable energy ratio: e.g. 30% Editor’s Note: Whether the NSCE collect the energy data directly or by using existing enabler service (e.g. A-DCCF) is FFS. 6. The NSCE server carries out slice modifications in accordance with the policy action defined in Step  1, through its interaction with the Slice OAM and the 5GC. 6.Y18.1.2 Information Flows 6.Y18.1.2.1 General The following information flows are specified for VAL server policy. 6.Y18.1.2.2 Policy of Reducing Energy Consumption Table 6.Y18.1.2.2-1 shows the request sent by a consumer to an NSCE server for VAL server policy provisioning procedure.

Scheduling period O Indicates the scheduling of policy in terms of time. >Start time M Indicates the scheduled start time. >End time M Indicates the scheduled end time.

Table 6.Y18.1.2.3-1: Policy of Promoting renewable energy consumption Information element Status Description Policy O Promote renewable energy usage >Area of interest M The service area for which the policy profile applies, which can be expressed as a geographical area (e.g. geographical coordinates), or a topological area (e.g. a list of TA). >Trigger event M Threshold information, i.e. when renewable energy reached a threshold % >Recommended action M Examples: • Modification of PDU sessions/max number of UEs (step for increase in %). • Increase slice capacity.

The DN energy analytics is performed per DNN/ DNAI and may be used to trigger the application server migration to different cloud. The analytics are based on NWDAF analytics and UPF/DN measurements on user plane load as well as edge/app side measurements on the energy consumption. Information/analytics on renewable energy used for providing application services is needed to support flexibility adjustment of the execution of workloads with GHG emissions. However, analytics relevant to renewable energy used for providing application services is missing. Enhancements to the DN Energy Efficiency analytics is required. The DN Energy Efficiency analytics as specified in clause 8.18 of 3GPP TS 23.436 [yy11] is enhanced as follows (new text in bold italics):

6.6.1.1 Procedure
Figure 6.6.1.1-1 illustrates the procedure for a consumer (e.g., VAL server, AIMLE server) to subscribe for AI/ML energy consumption analytics generated from data collected from VAL UEs while the VAL UEs are performing AI/ML operations. Pre-conditions: 1. ADAE Client (ADAEC) is connected to the ADAE Server (ADAES). 2. Data producers (e.g., VAL Clients) may be pre-configured with data producer profiles for the data they can provide. ADAES and ADAEC have discovered available data producers and their data producer profiles. Figure 6.6.1.1-1: ADAES support for AI/ML energy consumption analytics 1. An analytics consumer (e.g. VAL Server, AIMLE Server) sends an AI/ML energy consumption analytics subscription request to an ADAES. The subscription request includes an Analytics ID “AI/ML energy consumption analytics”, ML model identifier, AIML operation, energy consumption metrics, and other information as defined in Table 6.6.1.2.1-1. 2. The ADAES validates the subscription request and performs authentication and authorization checks to determine if the consumer is authorized to subscribe for the requested analytics. If authorization is successful, the ADAES stores the subscription request information, assigns a subscription ID, and sends a subscription response indicating successful subscription and includes the subscription ID. 3. The ADAES maps the analytics ID to a list of data collection event identifiers and determines a list of data producer IDs for the data collection event identifiers. The determination of data producer IDs is based on data producer profiles. 4. The ADAES sends an AI/ML energy consumption data collection subscription request to the ADAECs determined in step 3. The subscription request includes information as defined in Table 6.6.1.2.4-1. Data collection at the VAL UE(s) reuses the EVEX mechanism defined in 3GPP TS 26.531 [12]. 5. Each ADAEC configures the data producers (i.e., VAL client or AIMLE client) for collecting data (e.g., duration of AI/ML operation, % resource utilization for AI/ML operation) for AI/ML energy consumption analytics requested in the data collection subscription request. 6. The ADAEC sends an AI/ML energy consumption data collection subscription response to acknowledge the ADAES. The response includes a status and a subscription ID for the data collection. 7. The data producers perform AI/ML operations when triggered (e.g., ML model training) using the indicated ML model and collect data for AI/ML energy consumption analytics based on the configured data collection requirements. 8. At the completion of AI/ML operation, the ADAEC sends an AI/ML energy consumption data collection notification to the ADAES. The data notification includes the data collection subscription ID and the information as defined in Table 6.6.1.2.6-1. 9. The ADAES performs analytics relevant operations to generate the AI/ML energy consumption analytics based on the data received from the ADAECs. The ADAES uses the data collected by the ADAECs to calculate the AI/ML energy consumption analytics. NOTE: How the collected data are used to calculate energy consumption is up to implementation. 10. The ADAES sends an AI/ML energy consumption analytics notification to the consumer. The analytics notification includes the analytics subscription ID and the information as defined in Table 6.6.1.2.3-1.

6.8.1.1 Procedure
Figure 6.8.1.1-1 outlines the procedure, where Steps 1-4 represent existing operations. Step 5 introduces a new function in which the NSCE server monitors energy-related information for a network slice. Step 6 involves the NSCE server taking action to adjust the slice, either to conserve energy or to encourage the use of renewable energy sources. Figure 6.8.1.1-1: VAL server policy provision and enforcment for energy optimization 1. The consumer (VAL, SEAL Server) sends a VAL server policy provisioning request to the NSCE server by following clause 9.5 of 3GPP TS 23.435 [13]. New energy saving related policies (see examples in clause 6.8.1.2) are added: a. Based on the monitored energy consumption of a network slice - categorized by energy source (renewable or non-renewable) - over a specific duration (such as one hour) or as accumulated over a longer period (for example, a calendar month), slice modification is triggered when the measured value exceeds or falls below a defined threshold. This modification may involve reducing the slice's maximum throughput, slightly increasing allowable latency, or decreasing redundancy levels (such as removing a redundant UPF instance or redundant RAN cell). b. Based on the monitored renewable energy ratio of a network slice, a slice modification with predefined parameters is triggered when the energy ratio or crosses a specified threshold. Such modifications may include increasing the slice’s maximum throughput, raising allowable latency, expanding the maximum number of supported UEs, or increasing the maximum number of PDU sessions. The action of the above policy may include charging policy update when slice SLA is modified to save energy to attract the VAL server to use the policies. 2. The NSCE server performs a VAL server policy check. This is the same as step 2 in clause 9.5.2.1, 3GPP TS 23.435 [13]. 3. The NSCE server performs Slice Harmonization. This step is the same as clause 9.5.2.1.4 Policy harmonization, 3GPP TS 23.435 [13]. 4. The NSCE server sends back a VAL server policy provisioning response to the Consumer (VAL/ASP), confirming policy provision. This is the same as step 2 in clause 9.5.2, 3GPP TS 23.435 [13]. 5. The NSCE server initiates the retrieval of energy consumption data from the slice OAM (3GPP TS 28.554 [6]) to monitor energy-related information, including but not limited to the following parameters: a. slice accumulated energy consumption refers to summing the average energy usage recorded during each slice OAM measurement interval (for example, every 15 minutes) by the OAM system and aggregating it into the total energy consumption over an extended period, such as a calendar month b. slice average energy consumption: e.g. Energy-Consumption/hour c. slice renewable energy ratio: e.g. 30% Editor’s Note: Whether the NSCE collect the energy data directly or by using existing enabler service (e.g. A-DCCF) is FFS. 6. The NSCE server carries out slice modifications in accordance with the policy action defined in Step 1, through its interaction with the Slice OAM and the 5GC.

6.9.1 Solution Description
In 3GPP TS 23.436 [11], the DN Energy Efficiency analytics, ADAES provides analytics on the energy consumption /efficiency of an edge platform (including the EESs / EASs). The DN energy analytics is performed per DNN/ DNAI and may be used to trigger the application server migration to different cloud. The analytics are based on NWDAF analytics and UPF/DN measurements on user plane load as well as edge/app side measurements on the energy consumption. Information/analytics on renewable energy used for providing application services is needed to support flexibility adjustment of the execution of workloads with GHG emissions. However, analytics relevant to renewable energy used for providing application services is missing. Enhancements to the DN Energy Efficiency analytics is required. The DN Energy Efficiency analytics as specified in clause 8.18 of 3GPP TS 23.436 [11] is enhanced as follows (new text in bold italics):

eb1343f2cdb3d270d65fac7ddb0d0638
23.700-44
8.18.2 Procedure
Figure 8.18.2-1 illustrates the procedure for DN energy efficiency analytics enablement solution. Pre-conditions: 1. Data producers (e.g. A-ADRF, EAS, EES) may be pre-configured with data producer profiles (as in Table 8.2.4.8-1) for the data they can provide. ADAES has discovered available data producers and their data producer profiles. Figure 8.8.2.1-1: ADAES support for DN energy analytics 1. The VAL server sends a DN energy analytics request/subscription request to ADAES to perform analytics on the DN Energy Consumption/Efficiency for one or more DNs/EDNs, Event ID= “DN energy analytics”, “Energy analytics per application service”, or “Ratio of renewable energy analytics”, for a given DN service area (or subarea) and a given time window. The message in the request/subscription request is as described in Table 8.18.3.2-1. 2. The ADAES authorizes the VAL request. The ADAES responses to the analytics request. The message in the response is as described in Table 8.18.3.4-1. 3. The ADAES requests and receives from the EAS /VAL servers hosted at the serving and target DNs (within the VAL service area). 3a. (If Event ID= “DN energy analytics” in step 1) expected application service load and traffic schedules for the ongoing or future sessions within the area. Such data include traffic schedule report for the VAL Server, and this step re-uses the step 3 to 10 of clause 8.8.2.1. 3b. (If Event ID= “Energy analytics per application service”, or “Ratio of renewable energy analytics” in step 1) energy usage data at the DN per application, and/or in a time period, and/or the type of energy resources used. 4. The ADAES calculates the expected energy consumption or efficiency based on the received traffic and load data for the given DNN/DNAI based on the request. NOTE: How the collected data are used to calculate energy efficiency metric is up to implementation. 5. (Optional) The ADAES obtains the corresponding trained ML model based on procedure in 3GPP TS 23.482 clause 8.3.2 and performs analytics to derive the predicted energy consumption at the target area and time horizon. The analytics outputs can be the statistics or predicted energy consumption / efficiency for the given DNN/DNAI. 6. The ADAES sends a DN energy analytics response/notifications with the energy consumption/efficiency analytics output data to the VAL server. The message in the analytics response/notifications is as described in Table 8.18.3.3-1. Based on 6, the VAL server can use these analytics as input to trigger pro-actively: - an application server migration to a different edge cloud or to a centralized cloud as a way of reducing the energy consumption for the edge (if consumption is expected to be very high (e.g. higher than a pre-configured threshold)). - an application server offboarding and the instantiation of a new server at the target edge/centralized cloud to minimize energy consumption of the edge platform (taking into account the system wide energy efficiency).

The following are the procedures to introduce how LMS subscribes the energy related information analysis from ADAES (clause  6.x10.1.1) and how LMS utilizes the obtained energy related information analysis to reduce the energy consumption for the location services (clause  6.x10.1.2). 6.x10.1.1 Procedure of LMS subscription for the energy related information analysis Figure  6.x10.1.1-1 illustrates the high-level procedure of the LMS subscription for the energy related information analysis. The LMS may subscribe to the ADAES for the analysis of energy related information. Figure  6.x10.1.1-1: Procedure of LMS subscription for the energy related information analysis 1. LMS may subscribe the energy information analysis related to location services from ADAES, including the analysis ID (e.g., energy consumption information), the service ID, the target area, the energy type (e.g., energy consumption), the energy information granularity (e.g., per VAL UE per location service), the filtering information (e.g., maximum energy consumption per VAL UE), the target UE ID, the trigger conditions, the time duration, etc. 2. The ADAES check if the LMS is authorized to request the energy information analysis. If the request is authorized, the ADAES responds to the LMS. 3. The ADAES sends the energy information analysis response to the LMS. 4. To obtain the analysis for the energy information, the ADAES may subscribe the energy related information (e.g., energy consumption information) from 3GPP Core network as described in clause  5.51.2.4 of 3GPP  TS  23.501  [235013], with the parameters received in service request in step  1. 5. When the trigger condition is met, the 3GPP Core network provides the energy related information (e.g., energy consumption information) to the ADAES per requested granularity (e.g., per VAL UE per location service). 6. Upon receiving the energy related information in step  5, the ADAES utilizes and generates the analysis for energy related information per VAL UE per location service, including the energy information statistic (e.g., maximum/average/minimum energy consumption information over a certain period of time, etc.), historical energy information, energy information predication (e.g., the time point of peak energy consumption), etc. Editor’s nNote: How the ADAES generates the analysis for energy related information and which information is FFS. 7. The ADAES notifies the energy information analysis to the LMS as service requested, including the analysis results generated in step  6. 6.x10.1.2 Procedure of LMS adjusting the location reporting configuration to save the energy Figure  6.x10.1.2-1 illustrates the high-level procedure of LMS adjusting the location reporting configuration to save the energy consumption. Figure  6.x10.1.2-1: Procedure of LMS adjusting the location reporting configuration to save the energy 1. Similar with step  1 of clause  9.3.5 in 3GPP  TS  23.434  [2343414], the VAL server sends a location reporting trigger to the LMS to activate a location reporting procedure for obtaining the location information of LMC with the parameters defined in clause  9.3.2.4 of 3GPP  TS  23.434  [2343414]. The location reporting trigger is periodical and the request also includes the energy saving indicator which means the LMS should consider saving the energy when performing the location services for the target UE. 2. Upon receiving the service request, the LMS decides to subscribe the energy information analysis from the ADAES for the target UE, following the procedure as described in clause  6.x10.1.1. The ADAES replies the energy related information analysis for the target UE to the LMS, and may include the energy information statistic (e.g., maximum/average/minimum energy consumption information over a certain period of time), energy information predication (e.g., the time point of peak energy consumption), etc. 3. Based on the energy related information analysis received from ADAES and the service request from VAL server, the LMS determines the UE location reporting configuration. For example, the LMS may decrease the reporting frequency when the UE’s energy consumption almost reaches its daily maximum, and vice versa. Or the LMS may pend the location reporting when the time point of peak energy consumption is coming based on the UE's energy information predication. 4. The LMS may interact with the VAL server regarding the determined UE location reporting configuration and sends the adaptive location reporting configuration provisioning messages as defined in clause  9.3.20 of 3GPP  TS  23.434  [2343414]. 5. If the VAL server approves the suggested location reporting configuration, the LMS sends such configurations to the LMC as defined in clause  9.3.3 of 3GPP  TS  23.434  [2343414]. If the VAL server rejects the suggested location configuration, the LMS may discard the configuration. 6. Considering the received location reporting configuration, the LMC reports the location information to the LMS dynamically when the location reporting trigger is met. 7. The LMS reports the received location information for the target UE to the VAL server. 6.x10.2 Architecture Impacts This solution has no impact on the existing architecture. 6.x10.3 Solution evaluation This clause provides an evaluation of the solution.

4.1 Architectural Assumptions
The following Architectural Assumptions are applicable to this Study: • The IMS and IMS DC architecture defined in TS 23.228 [2] is used as the basis for any enhancements. • An AS may be trusted or untrusted. • The functionality of existing standardized APIs (e.g., OMA APIs) exposing MMTEL services may be used where applicable when the MMTEL service does not depend on IMS DC media. • OMA APIs are not extended to support Data Channel and the principles outlined in TS 23.228 [2] Annex AD (IMS Subscribe/Notify framework for event monitoring).
