E.10 Reporting Access Network Information
29.2143GPPPolicy and charging control over Rx reference pointRelease 17TS
When the PCF receives the access network information, the PCF shall provide the corresponding access network information to the AF as defined in clause 4.4.6.7,
When the AF requested UE location, the PCF shall forward both, the received 3GPP access (NR or E-UTRA) and non-3GPP access (Trusted, Untrusted, or Wireline network) UE location, if available.
The PCF encodes 3GPP UE location received in the "eutraLocation" or "nrLocation" attribute into the 3GPP-User-Location-Info AVP and the non-3GPP Trusted, Unstrusted or Wireline access UE location as described in clauses E.6, E.7 and E.8. When the PCF received the "userLocationInfoTime" attribute, the PCF includes the User-Location-Info-Time AVP in the access network report to the AF to indicate when the UE location was last known.
NOTE: When the PCF receives both, the 3GPP and non-3GPP access UE locations, the "userLocationInfoTime" attribute, if received, indicates the last known 3GPP access UE location, and consequently, the User-Location-Info-Time AVP also indicates the last known 3GPP access UE location.
