1. A method for supporting location services for a user equipment (UE) performed by a Gateway Mobile Location Center (GMLC), the method comprising:
receiving from a Network Exposure Function (NEF) a location request for the UE, wherein the NEF received the location request from a second entity and the NEF is in a Public Land Mobile Network (PLMN) that is a Home PLMN (HPLMN) for the UE or a Visited PLMN (VPLMN) for the UE, the location request including a type of location request, a required location accuracy, a required location response time or some combination of these, wherein the NEF determines either the GMLC or a serving Access and Mobility Management Function (AMF) for the UE to obtain a UE location, wherein the NEF selects the GMLC based on: the type of location request, the required location accuracy, or the required location response time, or a combination thereof;
sending the location request to a Location Management Function (LMF via the serving AMF for the UE;
receiving the UE location or a confirmation of the location request from the LMF, wherein the LMF obtains the UE location by obtaining location measurements or a location estimate from at least one of the UE using a Long Term Evolution (LTE) Positioning Protocol (LPP) or a serving RAN for the UE using a New Radio (NR) Positioning Protocol A (NRPPa); and
sending the UE location or the confirmation of the location request to the NEF.
