Method and apparatus for using service capability information for user plane location

摘要

Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are described. In an aspect, a terminal informs a location server of service capabilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid requesting unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

1. A method comprising:
receiving from a service agent a request for a triggered service for a particular terminal, the triggered service having a trigger type selected from the group consisting of a periodic trigger and an area event trigger; determining whether a Secure User Plane Location (SUPL) service capabilities parameter indicative of supported services is available for the particular terminal; if the SUPL service capabilities parameter for the particular terminal is available, determining whether the particular terminal supports the triggered service using the SUPL service capabilities parameter; if the SUPL service capabilities parameter indicates the particular terminal supports the triggered service:
initiating a SUPL session with the particular terminal;exchanging trigger information including one or more trigger conditions associated with the service;receiving a notification from the particular terminal in response to occurrence of one or more of the trigger conditions; andtransmitting a trigger report message to the service agent in response to receiving the notification, the trigger report message indicative of the occurrence of the one or more trigger conditions.
