Method and system for estimating a subscriber's location in a wireless communication system service area
First Claim
1. A method for estimating a subscriber location of a subscriber unit in a wireless communication system service area comprising the steps of:
- at a receiver location in the wireless communication system service area, measuring a set of characteristics that describe a received ray of a subscriber signal;
in a computer model of the wireless communication system service area, determining a propagation path of a model ray launched from a location in the model of the wireless communication system service area that corresponds to the receiver location in the wireless communication system service area, wherein the model ray has model signal characteristics based upon the set of characteristics that describe the received ray of the subscriber signal, and wherein the model includes an object that can change the propagation path of the model ray; and
estimating a subscriber location in the wireless communication system service area in response to the propagation path of the model ray.

Abstract
At a receiver location in a wireless communication system service area, a set of characteristics that describe a received ray of a subscriber signal is measured. In a model of the wireless communication system service area, a propagation path of a model ray launched from a location in the model of the wireless communication system service area that corresponds to the receiver location in the wireless communication system service area is determined, wherein the ray has model signal characteristics based upon the set of characteristics that describe the received ray of the subscriber signal. Thereafter, a subscriber location in the wireless communication system service area is estimated in response to the propagation path of the model ray.
