Method and apparatus for supporting positioning for terminals in a wireless network
First Claim
1. A method for positioning a target device, comprising:
- exchanging a plurality of positioning messages between the target device and a location server in a positioning session that includes a plurality of transactions, each transaction covering a particular operation in the positioning session, the plurality of positioning messages supporting a plurality of positioning methods, wherein each positioning message includes a transaction identification (ID) to identify which transaction from a plurality of transactions in the positioning session for which each positioning message applies, wherein the plurality of positioning messages belong to one or more transactions; and
performing positioning based on the plurality of positioning messages.

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.
