Method and apparatus for performing session info query for user plane location
First Claim
1. A method of supporting location services, comprising:
- generating, by a terminal, a list of active location sessions that are currently in progress between the terminal and a location server, wherein the list of active location sessions comprises an indication of at least two active location sessions when the terminal identifies that there are at least two active location sessions currently in progress between the terminal and the location server;
generating a Secure User Plane Location (SUPL) UPDATE message comprising the list of active location sessions; and
sending the SUPL UPDATE message to the location server, without solicitation from the location server, to update the location server with the list of active location sessions.

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.

5. A method of supporting location services, comprising:
-
receiving a Secure User Plane Location (SUPL) UPDATE message comprising a first list of active location sessions, identified by a terminal, as currently in progress between the terminal and a location server, wherein the first list of active location sessions comprises an indication of at least two active location sessions when the terminal identifies that there are at least two active location sessions currently in progress between the terminal and the location server, the SUPL UPDATE message being received from the terminal without solicitation from the location server; and updating a second list of active location sessions at the location server with the first list of active location sessions in the SUPL UPDATE message. - View Dependent Claims (6)

7. An apparatus for supporting location services, comprising:
-
at least one processor; and memory coupled to the at least one processor to store program code, which when executed by the at least one processor, causes the processor to; generate a list of active location sessions that are currently in progress between a terminal and a location server, wherein the list of active location sessions comprises an indication of at least two active location sessions when the terminal identifies that there are at least two active location sessions currently in progress between the terminal and the location server; generate a Secure User Plane Location (SUPL) UPDATE message comprising the list of active location sessions; and send the SUPL UPDATE message to the location server, without solicitation from the location server, to update the location server with the list of active location sessions. - View Dependent Claims (8, 9, 10)
