Claim:
A method of allowing a mobile terminal to measure its own location through location information of a neighbor mobile terminal, the method comprising: receiving a temporary identifier of the neighbor mobile terminal and an effective time of the temporary identifier from the neighbor mobile terminal using near field wireless communication; transmitting a location information request to a base station using the temporary identifier if the effective time is remaining; and receiving the location information of the neighbor mobile terminal from the base station, wherein the received temporary identifier of the neighbor mobile terminal indicates that the mobile terminal is allowed to determine the location of the mobile terminal by using the location information of the neighbor mobile terminal adjacent to the mobile terminal, and is assigned from the base station before the temporary identifier is transmitted to the mobile terminal, wherein the location information of the neighbor mobile terminal is measured by the neighbor mobile terminal and is reported to the base station before the temporary identifier has been assigned to the neighbor mobile terminal, and wherein the effective time indicates a valid period for requesting the location information of the neighbor mobile terminal by using the temporary identifier.
