A system method for estimating Global Navigation Satellite System assistance data in a communications network. The method may comprise transmitting a location request from a mobility management entity to a location server, requesting a wireless device to transmit a first signal, and transmitting the first signal by the wireless device. A path delay estimate between the wireless device and location server may be determined as a function of an elapsed time for the request to the wireless to be received and as a function of an elapsed time for the transmitted first signal to be received. Satellite assistance data may then be determined as a function of current network time and the determined path delay estimate. |
