However, in the above-described location information reporting system, a call is connected between the location information server and the mobile station, and communication is performed at a higher layer, so that connection and negotiation take time. However, there is a large load such as consumption of power due to communication. Normally, mobile stations are also used as telephones, so if a call is connected to report location information, the location information will be reported periodically at regular time intervals. There is also a problem that it is difficult to make a telephone call.

Accordingly, an object of the present invention is to provide a location detection information request by defining an option of a paging service type of an incoming message for location detection in a call sequence from a location server in a private network. It is possible to report the radio status using the existing RT radio status report message, and it is possible to report the location information at high speed without connecting a call.
