In FIG. 4, when the portable wireless device 1 in the standby state enters the electromagnetically shielded room 7, the radio wave from the base station does not reach, and the callable state becomes the call impossible state (out of service area). Next, when the mobile wireless device 1 exits the electromagnetically shielded room 7, the mobile wireless device 1 that performs the location registration control emits a radio wave for requesting the location registration toward the base station (FIG. 6). When a station exists and returns the radio wave of the authentication request to the mobile wireless device 1, further negotiation is performed, the mobile wireless device 1 transmits an authentication response signal to the base station, and the base station sends a position registration acceptance signal to the mobile wireless device 1. 1 to complete the location registration. The portable wireless device detection apparatus according to the present embodiment receives the radio wave for the first position registration request in which the portable wireless device 1 is in the call state again after the portable wireless device 1 leaves the electromagnetic shield room 7. Radio waves are received by the broadband receiver 3 via the receiving antenna 2 shown in FIG.
Done in. The signal received by the broadband receiver 3 is collated with the frequency information used by the mobile communication system recorded in the database 5 by the computer 4, and it is determined whether the radio wave used by the mobile wireless device 1 or environmental noise. If it is, the alarm device 6 is operated and detection is performed.
