1. A method comprising:
- determining, by a mobile positioning center, that a mobile device placed an emergency communication to an emergency center, wherein the mobile positioning center is communicatively coupled to a location database and the emergency center;
determining, by the mobile positioning center, that the mobile device cannot provide a mobile device location;
receiving, at the mobile positioning center from the mobile device, an identifier of a detected device detected by a wireless radio of the mobile device;
locating, by the mobile positioning center, information in the location database associated with the identifier;
identifying, by the mobile positioning center, a location of the detected device based on the information;
determining, by the mobile positioning center, the mobile device location based upon the location;
determining an accuracy of the mobile device location based upon at least one of a type of the wireless radio of the detected device or a signal strength of the mobile device or the detected device; and
providing, by the mobile positioning center, the mobile device location and the accuracy of the mobile device location to the emergency center.

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.
