B.1 LCS privacy selection flow rule

23.2733GPP5G System (5GS) Location Services (LCS)Release 18Stage 2TS

A 5GS-MT-LR may be applied to more than one LCS privacy data in the LCS privacy profile, e.g. one or more privacy classes as defined in clause 5.4.2.2 and LPI as defined in clause 5.4.2.3. The 5GS-MT-LR may also require POI as defined in clause 5.4.4. The Privacy selection flow is shown in Figure B.1-1.

Figure B.1-1: Privacy selection flow diagram

Annex C (informative):
PNI-NPN architecture to support location service with signalling optimisation

Figure C-1 shows the PNI-NPN architecture to support location services with optimisation of signalling latency and privacy, with the corresponding functional descriptions are defined in clause 5.13.

When UE access the NG-RAN in the local network, during the registration procedure, NG-RAN selects the AMF in the public network. With appropriate configuration, local AMF cannot be selected as the serving AMF for the UE.

Assuming NG-RAN 1 is the serving RAN of UE, NG-RAN 2 and NG-RAN 3 illustrated in the figure below is for positioning signal measurement, and only supports NON UE NRPPA signalling transmission.
