"Processes for using a mobile communication station in a wireless communication network to measure the arrival times of radio signals respectively transmitted by a plurality ofAnd radio transmitters in the network to locate the position of a mobile station in a wireless communication network.And to determine the time of arrival of a radio signal in a radio communication station which operates in a network of wireless communication, and.Apparatus for use in locating the position of a mobile station in a wireless communication network, and to measure the time of arrival of a radio signal in it. A mobile station (MS) in a wireless communication network is used to measure the time of arrival of the respective radio signals transmitted respectively by a pluralidAde of radio transmitters (23, 28) in the network.The mobile communication station is provided with information indicative of real time difference (RTDS) of a difference between a time base (60) used by a radio transmitter (23) serving estau00e7Will mobile communication and bases of time used by the other respective radio transmitters.The mobile communication station determines, in response to the information of the difference of real time and on the time base used by the radio transmitter serving the mobile communication station.A plurality of points in time at which radio signals are expected to arrive at the respective station of mobile communication.For each radio signal, the mobile station monitors the arrival of the radio signal over a period of time after the point in time at which the radio signal is expected to arrive.
