<P>PROBLEM TO BE SOLVED: To enable position identification of a mobile station even when the mobile station is located inside a building or a tunnel, or when the mobile station is not equipped with an SPS receiver, so that timing information cannot be collected from the SPS, for example. <P>SOLUTION: A method includes: receiving transmission delay information from one or a plurality of non-serving cells in a cellular network; and determining a position of a mobile station at least partially on the basis of the transmission delay information received from the one or plurality of non-serving cells and positions of the one or plurality of non-serving cells. The method includes: transmitting a position identification pilot signal from the base station; transmitting the transmission delay information from the base station to the mobile station; and determining a position of the mobile station at least partially on the basis of the transmission delay information received from the base station, and at least partially on the basis of a known position of the base station. <P>COPYRIGHT: (C)2013,JPO&INPIT |
