Is for wirelessly receiving an audio signal or the like from the base station 2 installed to cover the communication area where the user is currently located, and transmitting and outputting the audio signal or the like wirelessly.

[0004] The base station 2 transmits and receives voice signals and the like to and from the portable device 1 existing in the coverage area covered by the radio. Specifically, the base station 2 receives from the control device 3 an input of an instruction to call the portable device 1 existing in the coverage area to be covered, and sends a control signal for calling to the portable device 1. Things.

[0005] The control device 3 stores in which communication area each portable device 1 is located.
, Or in response to an input of an instruction to call a specific portable device 1 from the base station 2, performs connection control, and sends the specific portable device 1 to the base station 2 corresponding to the call area where the specific portable device 1 exists. An instruction to call the portable device 1 is output.

That is, the control device 3 periodically receives an input of a location registration control signal from each portable device 1 via the base station 2, and based on the location registration control signal, the presence of each portable device 1 exists. The communication area is stored while being updated. For the method of such location registration, etc., see "Mobile Communication", edited by Masaaki Shinji, 1989, pages 172 to 17.
Since the description covers three pages, the detailed description is omitted here. For example, the portable device 1a in FIG. 4 performs transmission and reception with the base station 2a covering the communication area A.

As described above, in a general mobile communication system, since the control device 3 stores the position (communication area) of each portable device 1, the control device 3 uses this to store the position of each portable device 1. It is considered to be applied to the technology of searching where is.

In this case, as shown in FIG. 4, a position display terminal is connected to the control device 3 so that the information on the position of the portable device 1 stored in the control device 3 is searched and output. It should be left.

[0009]

As described above, in the above-mentioned conventional mobile communication system, when the carrier of the portable device falls down due to an accident or sudden illness, the carrier transmits a signal indicating emergency or the like. Although it is possible to notify the control device of an emergency, even if the position of the portable device is searched using the position display terminal of the control device, the radius of the communication area of one base station is at least several hundred meters. However, there is a problem that a detailed position cannot be known, and it is difficult to search for a portable device.

In a real mobile communication system, for example, in a place where radio waves are blocked by a building or an obstacle,
Since the radio wave of the portable device does not always reach the nearest base station, as in the portable device 1b of FIG. In the overlapping area, as in the portable device 1c in FIG. 4, it is not known which base station 2 covers each communication area to transmit and receive. That is, since only the approximate position can be determined by using the position display terminal, the search range is not necessarily limited when searching for a portable device.
There was a problem that it was difficult to search for a portable device.
