Method and System for Determining the Position of a Mobile Station
First Claim
1. A method of determining a location of a mobile device, the method comprising:
- receiving a signal with a known radio transmission pattern at the mobile device from each of a plurality of transmitting devices;
correlating each received signal with a corresponding signal that has a same known radio transmission pattern to determine a time the signal traveled between the corresponding transmitting device and the mobile device; and
determining the location of the mobile device based on the time the signal travelled between the corresponding transmitting device and the mobile device.

Abstract
A method of determining the location of a mobile device is provided. The method receives a signal with a known radio transmission pattern at the mobile device from each of several transmitting devices. The method correlates each received signal with a corresponding signal that has a same known radio transmission pattern to determine the time the signal traveled between the corresponding transmitting device and the mobile device. The method determines the location of the mobile device based on the time the signal travelled between the corresponding transmitting device and the mobile device. In some embodiments, determining the location of the mobile device does not require calculating a distance between the mobile device and any of the transmitting devices. In some embodiments determining the location of the mobile device includes solving a function that is dependent on the time the signals traveled between each corresponding transmitting device and the mobile device.
