PURPOSE: A method for servicing location information using a wireless communication network is provided to perform the first location tracing by using location information based on cells capable of being traced through the wireless communication network, and to trace locations by using a detailed first tracing terminal and first tracing information. CONSTITUTION: A location tracing server receives the first location tracing request, and receives first location information of a location announcing terminal traced in a wireless communication network, then informs a requester of the first location information. The location tracing server receives the second location tracing request, and supplies the first location information to at least more than two second location tracing terminals, then requests the second location tracing. The location tracing server receives present location information of the more than two second location tracing terminals. The location tracing server calculates a location of the location announcing terminal on the basis of the present location information, and transmits the calculated location to the more than two location tracing terminals. The location tracing server receives final location information of the location announcing terminal, by repeatedly performing the step of receiving the present location information and the step of transmitting the calculated location of the location announcing terminal, and supplies the final location information to the requester.
