Zusammenfassung:PROBLEM TO BE SOLVED: To recognize timing corresponding to the completion of positioning and to acquire an accurate positioning result in a mobile unit carrying out positioning at request from another terminal or the like. SOLUTION: The mobile unit 10 comprises: a storage section 121 storing a positioning result; a GPS positioning request processing section 111 receiving a positioning request of the own unit 10 by GPS positioning and transmitting information that shows the positioning result by GPS positioning, to a network N; a GPS processing section 13 carrying out positioning by GPS positioning and storing the positioning result in the storage section 121; an RTT positioning request processing section 112 receiving a positioning request of the own unit 10 by RTT positioning and transmitting information used for positioning operation by RTT positioning; and a final positioning result receiving section 113 receiving the positioning result of positioning operation performed by an LCS processing server 20 by RTT positioning in response to the transmission of the information and storing the information that shows the positioning result, in the storage section 121.
