1. A method for calculating a time delay by a repeater in a mobile communication network, comprising the step of:

  • (a) determining an initial estimated position of a mobile communication terminal whose position is to be measured;

    (b) estimating a respective distance between a serving base station and an adjacent base station and the mobile terminal using the initial estimated position;

    (c) estimating a time difference of arrival of a serving base station signal and an adjacent base station signal received by the mobile terminal using the estimated distances;

    (d) receiving the time difference of arrival of the serving base station signal and the adjacent base station signal measured from the mobile terminal;

    (e) calculating a difference between the estimated time difference of arrival and the measured time difference of arrival; and

    (f) determining the difference as a repeater time delay existing in the serving base station of the mobile terminal, if said difference is larger than a predetermined threshold value.
