Method and apparatus for accurately locating a communication device in a wireless communication system
First Claim
1. A method for a system infrastructure of a wireless communication system to accurately locate a communication device in the wireless communication system, the method comprising the steps of:
- determining an approximate geographic location of the communication device;
transmitting to the communication device, based on the approximate geographic location, at least a request for a more accurate geographic location of the communication device;
receiving from the communication device the more accurate geographic location; and
conveying the more accurate geographic location to a target device.

Abstract
A wireless communication system employs a method and apparatus for accurately locating a communication device in the system. The communication system includes a system infrastructure that provides communication services to communication devices distributed throughout the communication system. Either on its own or, more preferably, responsive to a request from a requesting device for an accurate location of a particular communication device, the system infrastructure determines an approximate geographic location of the communication device. Based on the approximate location, the infrastructure transmits a request to the communication device for a more accurate location of the device preferably together with a map of an area that includes the approximate location of the device. The communication device preferably displays at least the map to a user of the device and, responsive to user input, transmits the more accurate location of the device to the system infrastructure. After receiving the more accurate location, the system infrastructure conveys the location to a target device preferably identified in the original location request received by the infrastructure.

35. A method for a communication device to assist a system infrastructure of a wireless communication system in providing an accurate geographic location of the communication device to a target device, the method comprising the steps of:
-
receiving, from the system infrastructure, a request for an accurate geographic location of the communication device and a first map of an area that includes a first approximate geographic location of the communication device;
displaying at least the first map to a user of the communication device;
receiving, from the user, an indication on the first map corresponding to a second approximate geographic location of the communication device, the second approximate geographic location being more accurate than the first approximate geographic location;
conveying the second approximate geographic location and a request for a second map to the system infrastructure;
receiving the second map from the system infrastructure, the second map corresponding to an area that includes the second approximate geographic location and being of a higher resolution than the first map;
displaying the second map to the user of the communication device;
receiving, from the user, an indication on the second map corresponding to a location of the communication device; and
conveying the location of the communication device to the system infrastructure for subsequent delivery to the target device.
