Wireless location is to determine the position of the Mobile Station (MS) in wireless communication networks. Due to the measurements with large errors, location schemes give poorer performance in Non-Line-Of-Sight (NLOS) environments. This paper illustrates methods to integrate all the available heterogeneous measurements to achieve more accurate location estimation. The proposed hybrid schemes combine Time Of Arrival (TOA) at seven BSs and Angle Of Arrival (AOA) information at the serving BS to give location estimation of the MS.
