Abstract
A method for determination of a repeater time delay in a mobile communication network, without affecting a correct positioning of a mobile terminal, is disclosed. The method includes the steps of determining an initial estimated position of a mobile communication terminal to be measured its position, estimating a respective distance between a serving base station and an adjacent base station and the mobile terminal using the initial estimated position, 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, receiving the time difference of arrival of the serving base station signal and the adjacent base station signal measured from the mobile terminal, calculating a difference between the estimated time difference of arrival and the measured time difference of arrival, and 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. The present invention makes it possible to estimate in advance the clock error in the terminal owing to the repeater tim…
