5.2.12.1 General
The following Data Set Identifiers shall be considered in this release: Subscription Data, Policy Data, Application data and Data for Exposure. The corresponding Data Subset Identifiers and Data (Sub)Key(s) are defined in Table 5.2.12.2.1-1. The set of Data Set Identifiers shall be extensible to cater for new identifiers as well as for operator specific identifiers and related data to be consumed. The following table illustrates the UDR Services. Table 5.2.12.1-1: NF services provided by UDR NF service Service Operations Operation Semantics Example Consumer(s) Data Management (DM) Query Request/Response UDM, PCF, NEF Create Request/Response NEF Delete Request/Response NEF Update Request/Response UDM, PCF, NEF Subscribe Subscribe/Notify UDM, PCF, NEF Unsubscribe UDM, PCF, NEF Notify UDM, PCF, NEF GroupIDmap Query Request/Response NRF, SCP The following table shows the Exposure data that may be stored in the UDR along with a time stamp using Data Management (DM) Service: NOTE: When the data in Table 5.2.12.1-2 need to be monitored in real time, they should be monitored directly at the originating NF (e.g. registration state changes may be monitored via the Namf_EventExposure service) and not use the stored information from UDR if it is not the latest. It is expected that such dynamically changing information (e.g. UE reachability status) is used for statistical purpose and analytics. Table 5.2.12.1-2: Exposure data stored in the UDR Category Information Description Data key Data Sub key Access and mobility information UE location Gives the Location or the last known location of a UE (e.g. Tai, Cell Id… both 3GPP and non-3GPP access location) SUPI or GPSI UE time zone Current time zone for the UE SUPI or GPSI UE Access type 3GPP access or non-3GPP access SUPI or GPSI UE RAT type Determined as defined in clause 5.3.2.3 of TS 23.501 [2].

5.2.12.2.1 General
The operations defined for Nudr_DM service use following set of parameters defined in this clause: - Data Set Identifier: uniquely identifies the requested set of data within the UDR (see clause 4.2.5). - Data Subset Identifier: it uniquely identifies the data subset within each Data Set Identifier. As specified in the procedures in clause 4, e.g. subscription data can consist of subsets particularised for specific procedures like mobility, session, etc. - Data Keys defined in Table 5.2.12.2.1-1 For Nudr_DM_Subscribe and Nudr_DM_Notify operations: - The Target of Event Reporting is made up of a Data Key and possibly a Data Sub Key both defined in Table 5.2.12.2.1-1. When a Data Sub Key is defined in the table but not present in the Nudr_DM_Subscribe this means that all values of the Data Sub Key are targeted. - The Data Set Identifier plus (if present) the (set of) Data Subset Identifier(s) corresponds to a (set of) Event ID(s) as defined in clause 4.15.1 An NF Service Consumer may include an indicator when it invokes Nudr_DM Query/Create/Update service operation to subscribe the changes of the data, to avoid a separate Nudr_DM_Subscribe service operation. Depending on the use case, it is possible to use a Data Key and/or one or multiple Data sub keys to further identify the corresponding data, as defined in Table 5.2.12.2.1-1 below. Table 5.2.12.2.1-1: Data keys Data Set Data Subset Data Key Data Sub Key Access and Mobility Subscription data SUPI Serving PLMN ID and optionally NID SMF Selection Subscription data SUPI Serving PLMN ID and optionally NID UE context in SMF data SUPI PDU Session ID or DNN Subscription Data (see clause 5.2.3.3.1) SMS Management Subscription data SUPI Serving PLMN ID and optionally NID SMS Subscription data SUPI Serving PLMN ID and optionally NID Session Management Subscription data SUPI S-NSSAI DNN Serving PLMN ID and optionally NID Slice Selection Subscription data SUPI Serving PLMN ID and optionally NID Group Data (NOTE 5) Internal Group Identifier or External Group Identifier - Identifier translation GPSI SUPI Application Port ID, MTC Provider Information, AF Identifier Intersystem continuity Context SUPI DNN LCS privacy SUPI - LCS mobile origination SUPI - UE reachability SUPI - Group Identifier Translation Internal Group Identifier or External Group Identifier - UE context in SMSF data SUPI - V2X Subscription data SUPI - A2X Subscription data SUPI - ProSe Subscription data SUPI - Ranging/SL Positioning subscription data SUPI - User consent SUPI Purpose ECS Address Configuration Information (See Table 4.15.6.3d-1) SUPI, Internal group identifier or external group identifier or any UE DNN, S-NSSAI, (Serving) PLMN ID (NOTE 7) MBS Subscription data (see clause 6.4.3 of TS 23.247 [78]) SUPI - Ranging/Sidelink Positioning Subscription data SUPI - Ranging/Sidelink Positioning privacy SUPI - Operator Determined Barring data (see clause 2.3 of TS 23.015 [90] and TS 29.505 [91]) SUPI - Shared data Shared Data ID - Application data Packet Flow Descriptions (PFDs) (NOTE 11) Application Identifier AF traffic influence request information for traffic routing AF transaction internal ID (See clause 5.6.7 and clause 6.3.7.2 of TS 23.501 [2]) For non-roaming and LBO: S-NSSAI and DNN , accompanied with Internal Group Identifier(s) and/or Subscriber Category(s) or SUPI or "any UE" indication For HR-SBO: HPLMN S-NSSAI and DNN and either: HPLMN ID and IP address, or SUPI, or "any UE" indication and HPLMN ID.

NOTE 2: Update of a Background Data Transfer data in the UDR requires a Data key to refer to a Background Data Transfer data as input data. NOTE 3: The Background Data Transfer includes the Background Data Reference ID and the ASP Identifier that requests to apply the Background Data Reference ID to the UE(s). Furthermore, the Background Data Transfer includes the relevant information received from the AF as defined in clause 6.1.2.4 of TS 23.503 [20]. NOTE 4: When the Data Key targets "any UE", then the request to UDR applies on Application data that applies on all subscribers of the PLMN. For encoding, see TS 29.519 [82]. NOTE 5: Group Data includes 5G VN group configuration, DNN and S-NSSAI specific Group Parameters and any other data related to a group stored in the UDR. NOTE 6: If a list of Internal Group IDs is used, the AF traffic influence request information request applies to the UEs that belong to every one of these groups, i.e. a single UE needs to be a member of every group in the list of Internal Group IDs. NOTE 7: When the Data Key targets "PLMN ID", then the request to UDR applies on subscription data about subscribers roaming in this PLMN. NOTE 8: In LBO roaming scenarios, when the AF request targets "any inbound roaming UEs", the AM influence information applies to the roaming subscribers from a PLMN or from any PLMN. NOTE 9: Retrieval of the stored Planned Data Transfer with QoS requirements data for all ASP identifiers in the UDR requires Data Subset but no Data Key or Data Subkey(s). NOTE 10: Update of a Planned Data Transfer with QoS requirements data in the UDR requires a Data key to refer to a Planned Data Transfer with QoS requirements data as input data. NOTE 11: Each PFD (as defined in TS 23.503 [20]) may be complimented with a source NF type which indicates the type of NF that has generated the PFD (i.e. AF or NWDAF). Absence of a source NF type indicates that the AF is the source of the PFD. NOTE 12: Further information about HR-SBO case and how these keys are used, see clause 4.3.6.1. NOTE 13: The ECS Address Configuration Information as part of application data is used for HR roaming case as defined in clause 6.5.2.6 of TS 23.548 [74]. The content of the UDR storage for (Data Set Id= Application Data, Data Subset Id = AF TrafficInfluence request information) is specified in Table 5.6.7-1 of TS 23.501 [2], in Table 5.6.16.2-1 of TS 23.501 [2] and in Table 5.6.17.2-1 of TS 23.501 [2]. This information is written by the NEF and read by the PCF(s). PCF(s) may also subscribe to changes onto this information. Wireline access specific subscription data parameters are specified in TS 23.316 [53].
