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.
