| |
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.4.1 General
| Spatial anchor discovery enables a SAn client or VAL server to discover spatial anchor(s) with the SAn server. The discovery of spatial anchor(s) is based on matching spatial anchor discovery filters provided in the request.
|
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.4.2 Procedure
| Figure 8.3.4.2-1 illustrates the procedure for spatial anchor discovery following the request-response model.
Pre-conditions:
1. The SAn client or VAL server has received information (e.g. URI, IP address) related to the SAn server; and
2. The SAn client or VAL server has received security credentials authorizing it to communicate with the SAn server.
3. For SAn client to trigger this procedure, the SAn client has received the required information from the VAL client over SAn-C interface.
Figure 8.3.4.2-1: Spatial anchor discovery
1. The requestor (e.g., SAn client or VAL server) sends a spatial anchor discovery request message to the SAn server to obtain information about spatial anchors of interest. The request includes a requestor identifier, security credentials, and can include spatial anchor discovery filters as described in clause 8.3.4.3.1. If the discovery request was triggered by a VAL client on a UE, the spatial anchor discovery request can additionally include a VAL client identifier and location of the client.
2. Upon receiving the request, the SAn server validates if the requestor is authorized for the request. If the requestor is authorized, the SAn server identifies spatial anchor(s) that satisfies the spatial anchor discovery filters.
NOTE 1: User preferences in the spatial anchor discovery filters can be compared with spatial anchor specific information.
For each matching spatial anchor, the SAn server checks whether the requestor is authorized to obtain the spatial anchor based on the identity and location of the requestor, and based on the allowed entities list. To determine the location of interest of the requestor or location of the requestor(client), the SAn server may use location information provided in the request. If location information is not provided in the request, the SAn server may obtain location information by invoking the 3GPP Core Network Location Services as described in 3GPP TS 23.273 [6] and 3GPP TS 23.502 [5] directly or via the NEF, or by invoking the SEAL Location Management APIs as described in 3GPP TS 23.434 [4].
When 'Area of interest' discovery filter is specified in the request, for spatial anchors on stationary objects, the SAn server finds 3D position of the object from the corresponding spatial map information. For spatial anchors associated with trackable objects, the SAn server can obtain the current position information of the object at the time of discovery from SEAL SM server through SEAL-X (AnM) reference point. Additionally, SAn server can consider estimated duration of tracking, which can be obtained from SM server, to determine spatial anchors in the area of interest.
3. The SAn server sends a spatial anchor discovery response to the requestor. If the SAn server has identified spatial anchor(s), the response includes an indication of success and the identified spatial anchors and may includes the recommended list of spatial anchors. The SAn server shall not incude the spatial anchors for which the state is inactive in the discovery response. Otherwise, the response includes an indication of failure and may include a reason for failure.
NOTE 2: The logic to generate a recommended list of spatial anchors is out of scope and implementation specific.
NOTE 3: The discovery response can include the List of discovered spatial anchors which is sorted starting with the closest spatial anchor to the location of the requestor(client).
4. Upon receiving the spatial anchor discovery response, if the response indicates success, the requestor can store the spatial anchor information in a spatial anchor cache. The requestor evaluates the validity conditions associated with the discovered spatial anchors prior to using the spatial anchor. If the requestor is the SAn client, the SAn client can provide spatial anchor information to the VAL client(s). Upon receiving valid spatial anchor information, VAL client(s) can access the service(s) associated with each spatial anchor.

| |
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.5.1 General
| Spatial anchor subscription enables a SAn client or VAL server to subscribe with the SAn server to receive notifications related to spatial anchors.
|
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.5.2 Procedures
| |
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.5.2.1 Subscribe
| Figure 8.3.5.2.1-1 illustrates the spatial anchor subscription procedure.
Pre-conditions:
1. The SAn client or VAL server has received information (e.g. URI, IP address) related to the SAn server; and
2. The SAn client or VAL server has received security credentials authorizing it to communicate with the SAn server.
3. The SAn client has received the required information from the VAL client via the SAn-C interface.
Figure 8.3.5.2.1-1: Spatial anchor subscription
1. The requestor (e.g., SAn client or VAL server) sends a spatial anchor subscribe request to the SAn server. The request includes a requestor identifier, security credentials, a notification endpoint, and event information for which the requestor is subscribing. The request may include an expiration time.
a. The requestor may include the "discovery" event type to indicate the SAn server to notify the requestor when the SAn server detects events related to the management of spatial anchors (e.g., creation, update, deletion, spatial anchor state changes (e.g. active, inactive, expired)) according to discovery event filters and spatial anchor filters provided in the request. If the requestor is a SAn client, the request includes a VAL client identifier.
b. The VAL server may include the "UE with spatial anchor interest" event type to indicate the SAn server to notify the VAL server when the SAn server detects UE(s) with interest in specific spatial anchors according to the spatial anchor of interest event filters and spatial anchor filters provided in the request.
c. The requestor may include the "spatial anchor in range" event type to indicate the SAn server to notify the requestor when the SAn server detects that spatial anchors become in range or out of range of the subscriber according to range event filters provided in the request. Range event filters can include a range for detecting spatial anchors, an indication to enable persistent search, the pose of the subscriber. If the requestor is a SAn client, the spatial anchor subscribe request includes a VAL client identifier.
2. Upon receiving the request from the requestor, the SAn server validates if the requestor is authorized for the request. If the requestor is authorized, the SAn server creates the subscription and stores the subscription information.
a. If the subscribed event is for "discovery", the SAn server starts monitoring spatial anchors management events according to the discovery event filters and spatial anchor filters.
b. If the subscribed event is for "UE with spatial anchor interest", the SAn server starts monitoring spatial anchors of interest according to the UE with spatial anchor interest event filters and spatial anchor filters. If the spatial anchors of interest have been discovered by a UE, the SAn server can obtain the UE location information from the 5GS or the SEAL Location Management service. Additionally, the SAn server can consider data analytics, such as UE mobility prediction. The SAn server may monitor the distance between UEs and the spatial anchor of interest to determine whether the UEs enters, exits or is within range of the spatial anchors of interest.
c. If the subscribed event is for "spatial anchor in range" and the requestor is a SAn client, the SAn server starts monitoring the corresponding UE location and direction corresponding to the pose information according to the range event filters and spatial anchor filters. The UE location information can be obtained by using capabilities of the 5GS or the SEAL Location Management service. Additionally, the SAn server can consider data analytics, such as UE mobility prediction. The SAn server monitors the distance between UEs and the spatial anchor of interest to determine whether the spatial anchors become in-range or out-of-range of the UE. If persistent search is enabled, the SAn server monitors location of the user (or UE) and pose of the user, along with a direction of movement, and discovers a list of spatial anchors which becomes in-range or out of range of the user device based on the location of the user device, the pose of the user and in the user's field of view. For spatial anchors associated with trackable objects, the SAn server can determine the in-range or out-of-range of the UE with the current position of the objects which are being tracked by SEAL SM server. Additionally, SAn server can consider trackable object mobility prediction which is provided by SEAL SM server based on the data analytics for position, direction and velocity of the object.
NOTE: How to do trackable object mobility prediction and estimate the duration of in-range object tracking is implementation specific and out of scope.
3. The SAn server sends a spatial anchor subscribe response to the requestor. If the SAn server has created the subscription, the response includes an indication of success, the subscription identifier and may include an expiration time; to maintain the subscription, the requestor shall send a subscription update request before the expiration time, otherwise the spatial anchor subscription expires. If the SAn server has not created the subscription, the response includes an indication of failure and may include a reason for failure.

| Figure 8.3.5.2.3-1 illustrates the procedure for a SAn client or VAL server to update a subscription with the SAn server.
Pre-conditions:
1. The SAn client or VAL server has subscribed for spatial anchor notifications with the SAn server;
Figure 8.3.5.2.3-1: Spatial anchor subscription update
1. The requestor (e.g., SAn client or VAL server) sends a spatial anchor subscription update request to the SAn server. The request includes the requestor identifier, security credentials and the subscription identifier and may include subscribed event information and expiration time.
2. Upon receiving the request from the requestor, the SAn server validates if the requestor is authorized for the request. If the requestor is authorized, the SAn server updates the subscription information.
3. The SAn server sends a spatial anchor subscription update response to the requestor. If the SAn server has updated the subscription, the response includes an indication of success and may include an expiration time. To maintain the subscription, the requestor shall send a subscription update request before the expiration time, otherwise the spatial anchor subscription expires. If the SAn server has not updated the subscription, the response includes an indication of failure and may include a reason for failure.

| |
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.7.1 General
| Spatial anchor group is a term that refers to the collection of spatial anchors based on locations (e.g. Museums in a city) or objects (e.g. items in a shop), etc. Spatial anchors can be grouped based on logical relationships. By organizing the spatial anchors into groups the spatial anchor owners can manage them efficiently. Also it adds more flexibility for the consumer applications of the spatial anchors to provide enriched experience to the end users. SAn server offers support which enables SAn client or VAL server for managing the spatial anchors as groups. This clause defines the procedures and information flows for managing the spatial anchor group(s).

26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.7.2 Procedures
| |
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.3.7.2.1 Spatial anchor group creation
| Figure 8.3.7.2.1-1 illustrates the spatial anchor group creation procedure through which the requestor SAn client or the VAL server can request the SAn server to create a spatial anchor group associating or linking a list of spatial anchors with the group. SAn server creates and stores the spatial anchor group and assigns a unique identifier (Spatial anchor group ID) to enable the requestor to perform spatial anchor group related operations.
Editor's note: Whether and how SEAL GMS capability can be extended to support SAn server in grouping the spatial anchors is FFS.
Pre-conditions:
1. The SAn client or VAL server has received information (e.g. URI, IP address) related to the SAn server; and
2. The SAn client or VAL server has received security credentials authorizing it to communicate with the SAn server.
Figure 8.3.7.2.1-1: Spatial anchor group creation
1. The requestor (e.g., SAn client or VAL server) sends a spatial anchor group create request to the SAn server. The request includes a requestor identifier, security credentials, list of spatial anchors identified by the spatial anchor IDs to be associated or linked as part of the spatial anchor group, human readable description about the spatial anchor group and service area where the spatial anchor group is accessible as described in Table 8.3.7.3.1-1.
2. Upon receiving the request, the SAn server validates if the requestor is authorized for the creation of spatial anchor group. If the requestor is authorized, the SAn server creates the spatial anchor group and assigns a unique identifier to it and stores the spatial anchor group related information provided in the step 1. The spatial anchor group related information contains spatial anchor group ID, list of spatial anchor IDs associated with the group, service area etc.
3. The SAn server sends a spatial anchor group create response as described in Table 8.3.7.3.2-1 to the requestor. If the SAn server created spatial anchor group, the response includes an indication of success and spatial anchor group identifier of newly created spatial anchor group and list of spatial anchor IDs associated with the created group. Otherwise, the response includes an indication of failure and can include a reason for failure.

| Figure 8.3.7.2.2-1 illustrates the spatial anchor group deletion procedure through which the requestor SAn client or the VAL server can request the SAn server to delete a spatial anchor group.
Pre-conditions:
1. The SAn client or VAL server has received information (e.g. URI, IP address) related to the SAn server; and
2. The SAn client or VAL server has received security credentials authorizing it to communicate with the SAn server.
3. For SAn client to trigger this procedure, the SAn client has received the required information from the VAL client over SAn-C interface.
Figure 8.3.7.2.2-1: Spatial anchor group deletion
1. The requestor (e.g., SAn client or VAL server) sends a spatial anchor group delete request to the SAn server. The request as includes a requestor identifier, security credentials, identifier of the spatial anchor group. If the requestor wants to delete more than one group, the request can carry the list of spatial anchor group IDs. If the requestor wants to delete the spatial anchors and its information also, the request can include an indication to delete the spatial anchors.
2. Upon receiving the request, the SAn server validates if the spatial anchor group exists and if the requestor is authorized to delete the spatial anchor group. If the requestor is authorized, the SAn server deletes the spatial anchor group and its associated information. If the request indicates to delete the spatial anchors associated with the group, then the SAn server deletes the spatial anchors associated with the group and the related information.
3. The SAn server sends a spatial anchor group delete response to the requestor. If its success response, it includes the list of spatial anchor group IDs that are deleted. It may also include the list of spatial anchors that are deleted if the request includes an indication to delete the spatial anchors. In case of failure, the response includes the reason for failure.

Figure 8.4.2.2-1: Spatial anchor usage information subscription
1. A consumer (e.g. VAL server) sends a spatial anchor usage information subscription request to the SAn server. The request can include the VAL server identifier, security credentials, a notification endpoint (e.g., IP address, FQDN, URI), and spatial anchor filters like spatial anchor identifiers, spatial anchor location information, position of the user, proximity distance, and application service identifier. It may also include the periodicity for reporting notification and sampling interval.
2. Upon receiving the request, the SAn server authorizes the VAL server subscription request and sends a spatial anchor usage subscription response to the consumer.
3. The SAn server samples the information related to spatial anchor usage based on the obtained data and the stored spatial anchor data as per the sampling interval. It provides notification to the consumer as per the reporting interval. The notification message includes spatial anchor ID, number of times spatial anchor discovered and accessed, spatial anchor density per location, user density per spatial anchor, spatial anchor services accessed information.

26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.4.4 Spatial anchor usage reporting
| |
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.4.4.1 General
| Spatial anchor usage reporting enables a spatial anchor consumer (e.g., SAn client or VAL server) to report spatial anchor usage to the SAn server.
|
26e140d21b097a2c000610e4bd7ffb34 | 23.437 | 8.4.4.2 Procedure
| Figure 8.4.4.2-1 illustrates the spatial anchor usage reporting procedure.
Pre-conditions:
1. The SAn client or VAL server has received information (e.g. URI, IP address) related to the SAn server;
2. The SAn client or VAL server has received security credentials authorizing it to communicate with the SAn server.
Figure 8.4.4.2-1: Spatial anchor usage reporting
1. The requestor (e.g., SAn client or VAL server) sends a spatial anchor usage report request to the SAn server. The request includes a requestor identifier, security credentials, and spatial anchor usage information as described in clause 8.4.4.3.1.
2. Upon receiving the request, the SAn server validates if the requestor is authorized for the request. If the requestor is authorized, the SAn server updates the spatial anchor usage information. The SAn server uses the spatial anchor usage information when notifying subscribers(s) as specified in clause 8.4.2.2.
3. The SAn server sends a spatial anchor usage report response to the requestor. If the SAn server successfully stored the spatial anchor usage information, the response includes an indication of success. Otherwise, the response includes an indication of failure and can include a reason for failure.
