    摘要： In a mobile telecommunications network, a mobile station (MS) is configured to generate and uplink transmit position measuring data prior to and/or during a call connection, without noticeably interrupting the user or degrading the quality of service provided. Position measuring data can be uplink transmitted over an idle traffic channel during a call set up operation for a brief moment while the call connection is being completed. Position measuring data can also be uplink transmitted during a call by selectively stealing data positions or burst positions in the uplink signal. The position measuring data is received by a plurality of base stations and uplink signal characteristics are measured and collected. The measured uplink signal characteristic data from several base stations is then used to determine a current approximate geographical location of the mobile station.

    摘要： A method and system are disclosed by which a round-trip calculation is used to determine the distance between a mobile radio station (MS) and a radio base station (BS) using the apparent uplink and downlink signal propagation air-times (e.g., T-up and T-down). As such, no absolute time reference is required. The MS and BS report to a service node in the mobile network the local departure and arrival times of the uplink and downlink signals, and calculate the apparent air-times, T-up and T-down. The distance, D, between the MS and BS can be calculated as D=c(T-up+T-down)/2, where "c" equals the speed of light. The distances, D1, D2 and D3, to at least three base stations whose locations are known, can be used in a triangulation algorithm to determine the MS's position.

    摘要： A time of arrival measurement apparatus is used to measure the time of arrival of a radio signal transmitted by a mobile communication station operating in a wireless mobile communication network. The apparatus is provided with information indicative of a predetermined point in time at which the radio signal is to be transmitted. The time of arrival measurement apparatus monitors for arrival of the radio signal only during a period of time after the predetermined point in time. The time of arrival measurement apparatus also receives information from which it can determine an informational content of the radio signal.
