Study on enhancement to the 5GC LoCation Services (LCS)
The objectives of this Technical Report are to enhance the service-based architecture used for location services in the 5G system, and corresponding Network Functions (NFs) and procedures, to meet the service requirements defined in, SA WG1 (e.g. TS 22.261 [2] and TS 22.071 [3]), including the consideration of roaming and non-roaming scenarios, and access via 3GPP as well as non-3GPP access technologies (un-trusted, and trusted in TR 23.716 [9]). Of particular consideration is how to support location services in 5GS and EPS interworking scenarios, and in non-3GPP access and 3GPP access interworking scenarios.
This Technical Report will need to consider related architectures and functions developed in RAN, and implications if any.
