15.2 Part 2: Gateway Service

This is the interface between the GeoMobility Server and Location Server that resides in the GMLC or MPC through which OpenLS services obtain position data for Mobile Terminals. This interface is modeled after the MLP specified in OMA 3.0 for Standard Location Immediate Service. 15.2.1 Use cases These use cases have been grouped into 3 priority categories, with priority 1 having the highest priority and the only case for mandatory support. The Gateway Service should support the following:
