1. A method for determining a repeater time delay of a base station in a mobile communication network, comprising the steps of:

  • (i) estimating an arrival time difference in a serving base station signal and an adjacent base station signal of a mobile communication terminal to be measured its position, and then calculating a time delay caused by a repeater in the serving base station using the estimated arrival time difference and a measured arrival time difference in the serving base station signal and the adjacent base station signal measured by the mobile communication terminal; and

    (ii) if a resultant value of a difference between the measured time difference of arrival and the estimated time difference of arrival, plus the calculated time delay by the serving base station repeater is larger than a predetermined first threshold value, then determining the resultant value as a repeater time delay of the associated adjacent base station.
