Abstract: In this paper,a mobile location-based dynamic positioning algorithm is proposed based on measured time of arrival(TOA). This algorithm can be used in cellular networks to estimate mobile location from mobile radio TOA information detected by several base stations(BS). The BS numbers and the corresponding weights utilized in this algorithm can be dynamically adjusted according to the distance between mobile station(MS) and serving BS. Location estimate can also be made if onlyTOA and angle of arrival(AOA) are measured by serving BS. Therefore, this algorithm could be applied to many mobile communication channel environments. Simulation results showthatthe location performance of this algorithm is satisfactory in three typical mobile communication channels.
