Abstract
A method for determining the location of a mobile device that has placed an emergency communication includes determining that an emergency communication has been made by a mobile device having a wireless radio and receiving, from the mobile device, an identifier of a first device detected by the wireless radio. If the first device is not fixed, the method includes sending a first location request to the first device to determine a first location of the first device. The method also includes determining a location of the mobile device based upon the first location and providing the mobile device location to a recipient of the emergency communication.
