Table 7.3.2.1-1 describes information elements for the spatial anchor profile stored in the SAn server.
| Information element | Status | Description |
|---|---|---|
| Spatial anchor ID | M | Identifier of the discovered spatial anchor. |
| Position
(NOTE 1) | O | The 3D geographic position of the spatial anchor in space (x, y and z coordinates). |
| Spatial map position
(NOTE 1) | O | Position information based on spatial map. It includes the identifier of the Spatial map and the corresponding localization information or object ID. |
| > Spatial map ID | O | Identifier of the spatial map. |
| >> Spatial map layer ID | O | Identifier of the spatial map layer if Spatial map ID is present. |
| >> Localization
(NOTE 2) | O | 3D position and pose of the VAL UE. |
| >> Object ID
(NOTE 2) | O | Identifier of the object on which the spatial anchor is produced. The object can be stationary or trackable. |
| Application specific Spatial anchor information | O | A container to contain application specific information. |
| VAL service information | M | Information about the application service associated with the spatial anchor. |
| > VAL Service ID | M | The identifier of the application service. |
| > Service endpoint | M | Endpoint information (e.g., URI, FQDN, IP address) used to communicate with the application service. |
| > Service connection information | O | The connection information (e.g., DNN, DNAI(s)) for establishing connectivity to the application service. |
| Service area | O | The service area where the spatial anchor is accessible. |
| Allowed entities list | O | Identity of entities (e.g. VAL client, VAL server or VAL service identity) which are permitted to discover the spatial anchor. |
| > Spatial anchor group ID | O | Identifier of spatial anchor group that the spatial anchor associates with. |
| Time period | O | Indicates time period or duration or time windows - comprising a start time and an expiry time. A spatial anchor is active during this time period. After the expiry time, the state of a spatial anchor becomes inactive. The time period may include one or more values (e.g. repeated over time/day). |
| Expiry handling indication | O | Indicates whether the spatial anchor has to be deleted or its state to be updated as inactive on expiry by the SAn server. Absence of this IE shall be considered that SAn server deletes the spatial anchor on expiry. |
| Spatial anchor state | O | Indicates the state of the spatial anchor (active or inactive). Spatial anchors in inactive state is not discoverable.Absence of this IE shall be considered as spatial anchor is in active state. |
|
NOTE 1:
One of the IEs shall be present.
NOTE 2:
If Spatial map ID is present, either one of the IEs shall be present.
