Abstract
A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters (350a, 350b) is disclosed. Embodiments of the novel system and method enable the geolocation system to determine if signals being received by the geolocation system arrive directly from a target mobile appliance or if the signals are passing through a repeater (350a, 350b) and therefore are subject to a known time delay. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.

- 1. In a method of determining the location of a mobile appliance in a wireless communication system having plural base stations and at least one repeater for communicating with the mobile appliance, where the wireless communication system has a network overlay geolocation system operably connected thereto, the improvement of determining whether a signal received from the mobile appliance by the geolocation system has passed through a first repeater.
- 7. The method of claim I wherein plural signals are received from the mobile appliance by the geolocation system and the step of determining if one of the plural signals has passed through the first repeater is based in part on a difference between the times of arrival of two of the plural signals at the geolocation system.
- 11. A method of determining the location of a mobile appliance in a wireless communication system having plural base stations and at least one repeater for communicating with the mobile appliance, and a mobile positioning center, wherein a plurality of geolocation sensors are co-located with the plural base stations, and wherein the at least one repeater is connected with a communication tether to the base station, and the mobile position center provides mobile information to the geolocation system, the improvement comprising the step of monitoring the communication system with the geolocation system and determining if a target mobile appliance is served by the at least one repeater.
- 22. A method of determining the location of a mobile appliance in a wireless communication system having plural base stations and at least one repeater station for communicating with the mobile appliance, wherein each of the at least one repeater station are connected to a respective one of the plural base stations with a communication tether, the improvement comprising the steps of detecting signals from a target mobile appliance on the communication tether and using a known delay attributed to the communication tether and the respective at least one repeater station to determine the location of the target mobile appliance.
-
25. A method for determining the location of a mobile appliance in a wireless communication system having plural base stations and at least one repeater station for communicating with the mobile appliance, wherein each of the at least one repeater stations are connected to a respective one of the plural base stations with a communication tether, the improvement comprising determining the location of the repeater station using mobile information parameters received from an MPC and using the location of the repeater station as the location of the mobile appliance.
- 26. A method for determining the location of a mobile appliance in a wireless communication system having plural base stations and at least one repeater station for communicating with the mobile appliance, wherein each of the at least one repeater station are connected to a respective one of the plural base stations with a communication tether, wherein the at least one translating repeater station relays a mobile appliance'"'"'s signal on a different channel than the signal transmitted by the mobile appliance, the improvement comprising relaying from the at least one repeater station information regarding the channel of the mobile appliance'"'"'s signal to a geolocation system and using the information to detect the mobile appliance'"'"'s signal and calculate the mobile appliance'"'"'s location.
- 30. A method for determining the location of a mobile appliance in a wireless communication system having plural base stations and plural repeaters, wherein the repeaters relay the mobile appliances signal on the same channel as the channel in which the signal was received, and where a mobile positioning center provides mobile information to assist in the location of the mobile appliance, the improvement of using the first signal received from the mobile appliance at each of the plural base stations to determine the location of the mobile appliance.
-
34. A network overlay geolocation system for locating a mobile in a host wireless communication system, said host wireless communication system having a base station and a repeater station connected by a communication tether, said network overlay geolocation system comprising a geolocation sensor attached to the communication tether between said base station and said repeater station.
-
35. A wireless communication system providing communication to and from a mobile appliance comprising:
-
a base station and a repeater station interconnected by a communication tether;
a mobile positioning center for providing mobile information;
a network overlay geolocation system with a geolocation sensor co-located at the base station;
wherein said tether is connected to said base station at an antenna feed interface, and said geolocation sensor is located on said tether prior to said interface.
