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, the plurality of positioning messages supporting a plurality of positioning methods, wherein each positioning message includes common parameters applicable for all positioning methods supported by each of the positioning messages, wherein at least one of the positioning messages is a Request Assistance Data message to request assistance data for a first positioning method, wherein the common parameters for the Request Assistance Data message comprises an approximate location of the target device determined using a second positioning method that is different than the first positioning method, 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 for a target device includes exchanging positioning messages that support a plurality of positioning methods between the target device and a location server. The positioning message may include common parameters applicable for all positioning methods. One of the positioning messages may be a Request Assistance Data message to request assistance data for a first positioning method, wherein the common parameters for the Request Assistance Data message includes an approximate location of the target device determined using a different positioning method. Another positioning message may be a Provide Assistance Data message to provide assistance data that is not in response to a request for assistance data, wherein the common parameters for the Provide Assistance Data message may include an approximate location of the target device or a current time.
