1 Scope p. 6
The present document specifies the operations and information coding for the Non-Access Stratum (NAS) layer protocol for supporting the Location Services (LCS) in the NG-RAN.
The present document is applicable to the User Equipment (UE) and to the Access and Mobility Management Function (AMF) or Location Management Function (LMF) in the 5G System (5GS).
The present document is developed in accordance to the general principles stated in TS 23.273.
2 References p. 6

3.1 Terms p. 7
For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
For the purposes of the present document, the following terms and definitions given in TS 22.261 apply:
satellite NG-RAN
PRU ON/OFF state:
This state is defined for a UE associated as a PRU with an LMF (i.e. after the successful completion of PRU association procedure). This state indicates whether the PRU functionality of the UE is activated (i.e. ON state) or deactivated (i.e. OFF state) while it is associated with an LMF.
UE operating as PRU:
From the UE perspective, a UE which supports PRU functionality and operates as PRU. From the network perspective, the UE allowed to operate as a PRU based on the UE subscription data and the PRU state is ON.
