Method and apparatus for supporting positioning for terminals in a wireless network
First Claim
1. A method for wireless communication, comprising:
- obtaining positioning information for a target device by a location server via a common positioning protocol, wherein the location server is capable of providing to another entity assistance data that is applicable to a different location than a location of the location server, the location server residing at one of a plurality of possible entities and using the common positioning protocol without conversion of the common positioning protocol regardless of where the location server resides, and the target device being one of the plurality of possible entities; and
determining location information for the target device by the location server.

Abstract
Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning may be supported by a location server that can reside in different entities. In one design, the location server may obtain positioning information (e.g., measurements) for a target device via a common positioning protocol. The location server may use the common positioning protocol regardless of where it resides and may communicate with other entities via this protocol. The location server may determine location information (e.g., a location estimate) for the target device based on the positioning information. In another aspect, positioning may be supported by transporting multiple positioning messages together. In yet another aspect, positioning may be supported by transporting a positioning message containing multiple parts defined by different organizations. In yet another aspect, positioning may be supported with shared measurement data units and/or shared assistance data units that may be applicable for different positioning methods.
