System and method for location boosting using proximity information
First Claim
1. A method of determining the location of a target mobile device in a communications network comprising the steps of:
- (a) selecting a set of mobile devices to be used in locating the target mobile device, the selecting including;
identifying mobile devices in proximity to the target mobile device according to a selected function;
wherein the selected function is based on a common parameter of information; and
wherein the common parameter of information is observed by mobile devices in the set of mobile devices,(b) sharing measurement data amongst the set of mobile devices and the target mobile device; and
(c) determining a location of the target mobile device as a function of the shared measurement data.

Abstract
A system and method for determining the location of a target mobile device in a communications network. A set of mobile devices in proximity to the target mobile device may be determined (210) as a function of a common parameter of information observed by mobile devices in the set. Measurement data may be shared (220) for the set of mobile devices and the target mobile device, and a location of the target mobile device (230) determined as a function of the shared measurement data. This sharing of measurement data may occur amongst the set of mobile devices and the target mobile device or may also occur at a communication network entity.
