Positioning protocol conveyance

摘要

Techniques for selecting positioning protocols consistent with the capabilities of the location server in a Secure User Plane Location (SUPL) based service are described. The SUPL Location Platform (SLP) transmits the service capabilities of the SLP, such as the positioning protocol capabilities of the SLP. The SLP transmits its capabilities of the SLP in an initiation message to the SUPL enabled terminal (SET) or after receiving an initiation message from the SET. The SET may transmit a positioning initiation message and the SLP and SET communicate to determine one or more position estimates for the SET. The SET may include in the positioning initiation message a positioning protocol positioning message that is consistent with the SLP service capabilities.

主权项

1. An apparatus comprising:
at least one processor configured to: receive from a Secure User Plane Location (SUPL) agent a request for position estimates for a SUPL enabled terminal (SET); provide an initiation message to the SET to start a location session, the initiation message including information on capability of the processor to provide support for specific positioning protocols; receive capabilities of the SET from the SET; communicate with the SET to determine at least one position estimate for the SET; and send the at least one position estimate to the SUPL agent.
