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
and TS 22.071
), 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
). 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.
