A cellular phone unit receives GPS satellite information of GPS satellites and base station information of base stations. It extracts the GPS satellite information and the base station information that meet transmission conditions, which are provided by a location information server, out of the obtained GPS satellite information and base station information. Those extracted information are sent to the location information server. Based on the receiving from the location information server a transmission condition in terms of the condition of accurate specifying of the location of cellular phone unit by the location information server, the cellular phone unit can extract proper GPS satellite information and base station information and send the extracted information to the location information server.
