A novel single base station mobile location algorithm: description and validation using a deterministic propagation model

The ability to support position location in wireless networks provides network operators with additional value services, as well as users with a host of new applications. This includes navigation, localization based services, network management and security applications. This paper presents a novel algorithm that makes use of a single base station (BS) to locate mobile terminals (MT) in cellular networks, by utilising a triangulation technique supported by minimal information about the environment in the BS neighbourhood. The algorithm is shown to perform well when operating in a microcellular scenario and perfect channel parameter estimation is assumed. Numerical results for several scenarios relating to 3rd generation (3G) microcellular operating parameters are presented using a 3D deterministic channel model.
