8.12  Location Reporting Proceduresp. 117

8.12.1  Location Reporting Controlp. 117

8.12.1.1  Generalp. 117

The purpose of the Location Reporting Control procedure is to allow the AMF to request the NG-RAN node to report the UE's current location, or the UE's last known location with time stamp, or the UE's presence in the area of interest while in CM-CONNECTED state as specified in TS 23.501 and TS 23.502. The procedure uses UE-associated signalling.

8.12.1.2  Successful Operationp. 117

Reproduction of 3GPP TS 38.413, Fig. 8.12.1.2-1: Location reporting control
Up
The AMF initiates the procedure by sending a LOCATION REPORTING CONTROL message to the NG-RAN node. On receipt of the LOCATION REPORTING CONTROL message the NG-RAN node shall perform the requested location reporting control action for the UE.
The Location Reporting Request Type IE indicates to the NG-RAN node whether:
  • to report directly;
  • to report upon change of serving cell;
  • to report UE presence in the area of interest;
  • to stop reporting at change of serving cell;
  • to stop reporting UE presence in the area of interest;
  • to cancel location reporting for the UE;
  • to report upon change of serving cell and to report UE presence in the area of interest.
If the Area Of Interest List IE is included in the Location Reporting Request Type IE in the LOCATION REPORTING CONTROL message, the NG-RAN node shall store this information and use it to track the UE's presence in the area of interest as defined in TS 23.502.
If the Additional Location Information IE is included in the LOCATION REPORTING CONTROL message and set to "Include PSCell" then, if Dual Connectivity is activated, the NG-RAN node shall include the current PSCell in the report. If a report upon change of serving cell is requested, the NG-RAN node shall provide the report also whenever the UE changes the PSCell, and when Dual Connectivity is activated.
If reporting upon change of serving cell is requested, the NG-RAN node shall send a report immediately and shall send a report whenever the UE's location changes.
If the Event Type IE is set to "stop UE presence in the area of interest", and if the Additional Cancelled Location Reporting Reference ID List IE is included in the Location Reporting Request Type IE within the LOCATION REPORTING CONTROL message, the NG-RAN node shall, if supported, stop reporting UE presence for all received Location Reporting Reference IDs.

8.12.1.3  Abnormal Conditionsp. 118

Interactions with Location Reporting Failure Indication procedure:
If the NG-RAN node receives a LOCATION REPORTING CONTROL message containing several Location Reporting Reference ID IE set to the same value, the NG-RAN node shall send the LOCATION REPORTING FAILURE INDICATION message with an appropriate cause value.
If the Location Reporting Request Type IE in the received LOCATION REPORTING CONTROL message contains the Event Type IE set to neither "UE presence in the area of interest" nor "change of serving cell and UE presence in the area of interest", but the Area of Interest List IE is present, the NG-RAN node shall ignore the Area of Interest List IE. and proceed with the Location Reporting Procedure.

The UE RADIO CAPABILITY INFO INDICATION message may also include paging specific UE radio capability information within the UE Radio Capability for Paging IE. If the UE Radio Capability for Paging IE includes the UE Radio Capability for Paging of NR IE and the UE Radio Capability for Paging of E-UTRA IE, the AMF shall, if supported, use it as specified in TS 23.501.
The UE radio capability information received by the AMF shall replace previously stored corresponding UE radio capability information in the AMF for the UE, as described in TS 23.501.
If the UE RADIO CAPABILITY INFO INDICATION message includes the UE Radio Capability - E-UTRA Format IE, the AMF shall, if supported, use it as specified in TS 23.501.
If the UE RADIO CAPABILITY INFO INDICATION message includes the XR Device with 2Rx IE, the AMF shall, if supported, store this information and use it accordingly.
