4.2.4 Reference points p. 13
SR1:
The reference point between the Sidelink (SL) Positioning and Ranging function in the UE and the SL Positioning/Ranging Server. This reference point is out of scope of this specification. It may be used for the configuration and application layer signalling.
SR5:
The reference point between the Sidelink (SL) Positioning and Ranging function in UEs. It is carried over PC5-U of the PC5 reference point.
PC5:
The reference point between the UEs. It also supports the Sidelink Positioning and Ranging operation defined by RAN WGs.
N1:
In addition to the relevant functions defined in TS 23.501 for N1, in the case of Ranging/SL Positioning Service, it is also used to convey the Ranging/SL Positioning policy and parameters (including service authorization) from AMF to UE, and to convey the UE's Ranging/SL Positioning Capability and PC5 Capability from UE to AMF.
N2:
In additionto the relevant functions defined in TS 23.501 for N2, in the case of Ranging/SL Positioning Service it is also used to convey the Ranging/SL Positioning policy and parameters (including service authorization) from AMF to NG-RAN.
NL10:
In addition to the relevant functions defined in TS 23.273, in the case of Ranging/SL Positioning Service, it used by LMF to get the location of Located UE/Reference UE from GMLC using the Application Layer ID.
4.2.5 Service-based interfaces p. 14
Nlmf:
In addition to the relevant services defined in TS 23.273, if the LMF support Ranging/SL Positioning service, it may be used to provide service to other NFs related to it.
Ngmlc:
In addition to the relevant services defined in TS 23.273, if the GMLC support Ranging/SL Positioning service, it may be used to get the location of Located UE/Reference UE from GMLC using the Application Layer ID in case of Sidelink Positioning and Ranging operation and it may be used to request to retrieve the mapping information between Application Layer ID and GPSI for UEs belong to different PLMNs and to check those UEs' Ranging/SL Positioning privacy profile.
Nudm:
In addition to the relevant services defined in TS 23.501 for Nudm, in the case of Ranging/SL Positioning service, services provided by UDM are used to get the related subscription information to AMF during Initial registration procedure or UE Configuration Update (UCU) procedure to inform AMF subscription information has changed.
Npcf:
In addition to the relevant services defined in TS 23.501 for Npcf, in the case of Ranging/SL Positioning service, services provided by H-PCF are used to provide SL Positioning and Ranging Service related parameters to V-PCF for UE and NG-RAN in the roaming case.
Nudr:
In addition to the relevant services defined in TS 23.501 for Nudr, in the case of Ranging/SL Positioning service, services provided by UDR are used to notify the PCF and the UDM of the update of the SL Positioning and Ranging-based service related information.
Namf:
In addition to the relevant services defined in TS 23.501 for Namf, in the case of Ranging/SL Positioning service, services provided by AMF are consumed by PCF to provide the Ranging/SL Positioning service related parameters for the UE and the NG-RAN to AMF, and to enable the AMF create or update UE context related to Ranging/SL Positioning service.
Nnef:
In addition to the relevant services defined in TS 23.501 for Nnef, in the case of Ranging/SL Positioning service, services provided by NEF are used by the Application Server to update Ranging/SL Positioning service related information of 5GC.
Nnrf:
In addition to the relevant services defined in TS 23.501 for Nnrf, in the case of Ranging/SL Positioning service, services provided by NRF are used to discover the PCF that supports Ranging/SL Positioning.
