Dynamic selection of user plane or control plane or control plane for location determination
First Claim
1. A method comprising:
- receiving into a positioning system a request for location of a mobile station;
in response to the request, making a determination, based on one or more factors, of whether to obtain mobile station location data through control plane signaling or user plane signaling;
if the determination is to obtain the mobile station location data through control plane signaling, then engaging in control plane signaling to obtain the mobile station location data; and
if the determination is to obtain the mobile station location data through user plane signaling, then engaging in user plane signaling to obtain the mobile station location data.

Abstract
A method and system for dynamic selection of user plane or control plane signaling for mobile station location determination. A positioning system receives a request for the location of a mobile station and then makes a determination, based on one or more factors, of whether to employ user plane signaling or control plane signaling to obtain mobile station location data. The factors may include mobile station capability, mobile station call state, mobile station support for user plane signaling, mobile station support for simultaneous voice and data communication, time, precision of requested location, subscriber preference, failure of control plane or user plane signaling, and preference specified by the request, among others. Given the determination, the positioning system then employs the selected signaling mechanism.

21. A positioning system arranged to selectively apply user plane signaling or control plane signaling on a case by case basis, the positioning system comprising:
-
a first signaling interface for communicating on a first network to engage in control plane signaling; a second signaling interface for communicating on second network to engage in user plane signaling; a processor; and data storage containing program logic executable by the processor upon receipt of a request for location of a mobile station, (i) to make a determination, based on one or more factors, of whether to obtain mobile station location data through control plane signaling or user plane signaling, (ii) if the determination is to obtain the mobile station location data through control plane signaling, then engaging in control plane signaling via the first network interface to obtain the mobile station location data, and (iii) if the determination is to obtain the mobile station location data through user plane signaling, then engaging in user plane signaling via the second network interface to obtain the mobile station location data.
