Abstract
A system for determining position of a mobile station is provided. The mobile station is equipped with a GPS receiver for receiving satellite signals from satellites. The system comprises a wireless wide area network (WWAN) configured to provide an acquisition assistance data for use in acquiring the satellite signals by the GPS receiver to the mobile station that is operable in the WWAN. A position determination entity (PDE) is provided to determine position of the mobile station based on the satellite signals received sent from the mobile station and the acquisition assistance data from the WWAN. A wireless local area network (WLAN) provides RF signals to the mobile station when the mobile station enters into a WLAN area. The mobile station determines the position of the mobile station using the WWAN transceiver and the GPS receiver at the time when the mobile station enters into the WLAN area. The MS then uses this position when it is operating in the WLAN and it is requested to provide location by a LBS application or by the emergency 911 calling service.
