Support for NetLocAccessSupport

The PCF supports the NetLocAccessSupport reporting on the N5 and Rx interface. The following describes about the noNetLocSupp:

  • Requesting SMF for Report of the requested Access Network Information

  • Reporting noNetLocSupp to AF

Note

NetLocAccessSupport Enumeration values:

  • ANR_NOT_SUPPORTED: Indicates that the access network does not support the report of access network information.

  • TZR_NOT_SUPPORTED: Indicates that the access network does not support the report of UE time zone.

  • LOC_NOT_SUPPORTED: Indicates that the access network does not support the report of UE location.

Requesting SMF for Report of the requested Access Network Information:

If the NetLoc feature is supported, PCF requests SMF to report the access network information by setting the AN_INFO policy control request trigger.

  • If the "reqData" attribute indicates the values MS_TIME_ZONE and USER_LOC_INFO, the SMF notifies the PCF that the access network does not support sharing access network information by including netLocAccSupp in UeCampingRep with ANR_NOT_SUPPORTED in the N7 Update Notify response.

  • If the "reqData" attribute indicates only MS_TIME_ZONE value, the SMF notifies the PCF that the access network does not support sharing UE time zone information reporting by including netLocAccSupp in UeCampingRep with TZR_NOT_SUPPORTED in the N7 Update Notify response.

  • If the "reqData" attribute indicates only USER_LOC_INFO value, the SMF notifies the PCF that the access network does not support sharing UE location information by including netLocAccSupp in UeCampingRep with LOC_NOT_SUPPORTED in the N7 Update Notify response.

Reporting noNetLocSupp to AF:

If the NetLoc feature is enabled, AF request the PCF to report the access network information.

  • N5 Interface: If the SMF notifies the PCF that the access network does not support sharing access network information, then

    • In N5 response to AF subscription, PCF contains noNetLocSupp attribute with NetLocAccessSupport enum as received from SMF and an event of the "AfEventNotification" data type in the "evNotifs" element with the "event" attribute set to the value ANI_REPORT.

  • Rx Interface: If the SMF notifies the PCF that the access network does not support sharing access network information, then

    • PCF sends a RAR command with the Specific-Action AVP set to INDICATION_OF_ACCESS_NETWORK_INFO_REPORTING_FAILURE and the NetLoc-Access-Support AVP set to 0 (NETLOC_ACCESS_NOT_SUPPORTED) to the AF requesting access network information in AAR command or STA command by including the NetLoc-Access-Support AVP set to the value of 0 (NETLOC_ACCESS_NOT_SUPPORTED ) to the AF requested the access network information in an STR command.

Note

If the NetLoc feature is not enabled in SMF, then

  • PCF includes noNetLocSupp attribute with ANR_NOT_SUPPORTED and an event of the "AfEventNotification" data type in the "evNotifs" attribute with the "event" attribute set to the value "ANI_REPORT" in N5 responses to AF subscription or include NetLoc-Access-Support AVP set to the value of 0 (NETLOC_ACCESS_NOT_SUPPORTED) in Rx responses to AF subscription.
