Method and apparatus for performing session info query for user plane location
First Claim
1. A method of supporting location services, comprising:
- sending a query message from a location server to a terminal to query for a list of active location sessions currently in progress, wherein the sending the query message comprises sending a Secure User Plane Location (SUPL) INIT message comprising a positioning method parameter set to a predefined value to indicate a session info query session;
receiving from the terminal a response message comprising the list of active location sessions, wherein the receiving the response message comprises receiving a SUPL REPORT message comprising the list of the active location sessions, and wherein the list of the active location sessions received from the terminal comprises an indication of at least two active location sessions identified by the terminal as being currently in progress between the terminal and the location server; and
terminating an active location session based at least in part on the list in the response message.

Abstract
Techniques for querying for information on location sessions in a user plane location architecture are described. In an aspect, a location server may send a query message to a terminal to query for information on active location sessions, e.g., when at least one location session for periodic triggered service or area event triggered service is deemed to be active. The terminal may return a response message containing a list of session identifiers (IDs) for the active location sessions, parameters for the active location sessions, capabilities of the terminal, etc. The location server may compare the information received from the terminal and information stored at the location server. The location server may terminate each location session deemed to be active at only the terminal or only the location server. The location server may restart or terminate each location session having inconsistent parameters at the terminal and the location server.
