Question: When an originating P-CSCF retrieves network-provided location information for inclusion in a SIP response confirmation, what specific AVP values must it include in the AA-Request to the PCRF if it hasn't requested access network information upon reception of the SDP offer?
Option 1: ACCESS_NETWORK_INFO_REPORT within the Specific-Action AVP + Required access network information within the Required-Access-Info AVP
Option 2: UE’s IP address using Framed-IP-Address AVP + Media-Component-Description AVP with Flow-Usage set to AF_SIGNALLING
Option 3: TWAN-Identifier AVP for direct location information + Geographical Identifier for routing within the Specific-Action AVP
Option 4: Session-ID for the ongoing Rx Diameter Session + Auth-Application-Id indicating location services
Explanation: According to procedures, if the P-CSCF hasn't requested access network information upon receiving the SDP offer, it must include ACCESS_NETWORK_INFO_REPORT within the Specific-Action AVP and required access network information within the Required-Access-Info AVP in the AA-Request to the PCRF, ensuring receipt of necessary location information for the SIP response confirmation.
