In order to reduce the adverse influence of nlos error to location performance, this algorithm firstly makes initial mobile position estimation by mean tdoa / toa measurements, then estimates nlos error within tdoa / toa measurements by parameters of tip 1 channel model, smoothes and reconstructs tdoa / toa measurements, and finally utilizes two step wls computation. the application of this algorithm under different cellular environments is also discussed and its effectiveness is demonstrated by simulation results. finally, the basic location method, location method implementation, network architecture, signaling protocol and interface, and location procedures of wcdma network mobile location are analyzed
