Systems and methods for network centric WLAN location of a mobile device

摘要

Systems, methods and devices for computing a mobile device location using network centric location measurements are described. In one potential embodiment, a location method comprises performing a user plane location session between a mobile device and a location server in order to reliably coordinate positioning of the mobile device. Based on the network centric coordination, the location server instructs one or more access points to obtain location measurements for the mobile device. The location server may then locate the mobile device based on the location measurements and possibly any mobile centric location measurements obtained from the mobile device using the user plane location session. The coordination of network centric positioning using the user plane location session may comprise transfer of SUPL and possibly LPP/LPPe positioning messages between the mobile device and location server.

1. A method of locating a mobile device comprising:
receiving, at a location server, positioning information from the mobile device via a user plane location session, the positioning information including data identifying at least one access point that the mobile device has received signaling from;
selecting, by the location server, the at least one access point for communication with based on the data identifying the at least one access point;communicating, based on the selecting, from the location server to the at least one access point an instruction to initiate a location measurement for the mobile device wherein the instruction is based at least in part on the received positioning information; receiving, at the location server, from the at least one access point, results of the location measurement; and determining a location of the mobile device based, at least in part, on the results of the location measurement.
