Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network using a Location Management Function (LMF) based control plane (CP) location solution. The LMF serves as the main anchor point for location support instead of an Access and Mobility Management Function (AMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may obtain location information for a UE via an AMF from a Next Generation Radio Access Network or the UE and may interact with a Gateway Mobile Location Center to receive location requests from and return location information to an external client. The LMF solution may be more efficient and require less implementation than an AMF based CP location solution.
