Method, system and apparatus for detecting a position of a terminal in a network |
摘要 |
<p>A method, system, and apparatus are provided for detecting a position of a terminal in a network accurately without a GPS receiver. In one example, a method for locating a position of a terminal (100) includes calculating a position of a base station (110-120); detecting a clock time difference between the base station and another base station; measuring a reception timing of a signal received by the base station from the terminal; and locating the position of the terminal using at least the position of the base station, the clock time difference, and the reception timing. <IMAGE></p> |
