Abstract

An E-OTD method for locating a mobile station using measurement information related to arrival of signals transmitted from base stations of different operators for obtaining the base station locations. When one operator does not have enough base stations for providing measurement information for location calculation, the SMLC of that operator acquires measurement information of base stations from at least one other operator using SMLC-SLMC communication protocol.
