Currently, when a mobile service makes a voice call using 5G radio access, the TS 102 232-5 IPMMIRI may include a SIP message containing PANI information with the Network Provided NR Cell Id used by the target service.
Similarly, when a mobile service makes a voice call using non-3GPP access (i.e. Voice over WiFi) the TS 102 232-5 IPMMIRI may include a SIP message containing PANI information with the UE local IP address, UDP/TCP source port and a time indication.
However, it is not currently possible to indicate the NR Cell Id or the non-3GPP Access information mentioned above in TS 102 232-5 IPMMIRI targetLocation, the definition of which is imported from TS 102 232-1.
This Change Request seeks to give the option of indicating the above information by importing UserLocation from TS 33.128 and using it in the list already available in TS 102 232-1 ASN.1 Common Parameters under Location.
