Abstract

PROBLEM TO BE SOLVED: To report the occurrence of emergency case to a police or the like speedily through simple operation with a mobile communication system with which an emergency message code is transmitted by operating the manipulator of mobile communication terminal in case of emergency and a nearby radio base station receiving this code transmits it to radio equipment having a device for reporting such a state to a monitoring person while adding its own position identification code. SOLUTION: Radio base stations 61-6n are installed at the interval of about 400 m and transmit position register signals. A PHS service control station 11 receives the position register signal of radio base station 61, writes it in its own memory and transmits it later together with the emergency message code. Information received at the radio base station 61 is sent through a connector 81 for PHS, radio exchange 91 and common signal line network 10 to the PHS service control station 11. The control station 11 displays a message and address data on a service console 12. Thus, the monitoring person immediately gets contact with the police.

Next, the operation of the mobile communication system according to the embodiment of the present invention will be described. In FIG. 1, radio base stations 61 to 6n transmit position registration signals representing position registration information of respective service areas as radio waves R1 to Rn. Now, assuming that the PHS terminal 11 is located in the service area of the radio base station 61, the PHS terminal 1
One transmission / reception control unit receives the radio wave R1 via the antenna 51. Next, after recognizing the position registration signal included in the radio wave R1, the transmission / reception control unit of the PHS terminal 11 writes the position registration information obtained from the position registration signal into its own memory.

Next, the transmission / reception control unit of the PHS terminal 11
If the location registration information written in the memory (hereinafter, referred to as new location registration information) is different from the old location registration information written in the memory before writing, the new location registration information is used as a location registration signal as an antenna. Transmit via 51. Thereby, the position registration signal is transmitted by the radio wave R
1 is received by the antenna 71 of the wireless base station 61 using the medium as a medium.

Further, the location registration signal is converted into a format for exchange connection by the PHS connection device 81, and then input to the exchange 91. As a result, the exchange 91 exchanges the location registration signal with the PHS service control station 11 via the common signal line network 10. As a result, the location registration signal is input to the PHS service control station 11 via the exchange 91 and the common signal line network 10, and the PHS service control station 11 obtains the new location registration signal of the PHS terminal 11 obtained from the input location registration signal. Write the location registration information to its own memory.

Now, assuming that the PHS terminal 11 has moved from the service area of the wireless base station 61 to the service area of the wireless base station 62, the PHS terminal 11 operates in the same manner as described above.
The location registration information on the radio base station 61 stored in the memory of the HS service control station 11 is updated to the location registration information on the radio base station 62. That is, always
The memory of the S service control station 11 stores the latest location registration information of the PHS terminal 11.

If a user in the service area of the radio base station 62 encounters a robbery or the like, the user presses the emergency button 41 of the PHS terminal 11 (FIG. 2). Press). Thereby, the transmission / reception control unit of the PHS terminal 11 transmits the signal to which the emergency message code is added as the radio wave R1 via the antenna 51. The radio wave R1 is received by the radio base station 62 via the antenna 72. After demodulating the emergency message code from the received signal, the wireless base station 62 outputs to the PHS connection device 81 an emergency signal obtained by adding the base station ID unique to the own station to the emergency message code.

As a result, the emergency signal is converted into a format required for exchange by the PHS connection device 81, and then input to the PHS service control station 11 via the exchange 91 and the common signal line network 10. PHS service control station 11
After recognizing the emergency message code and the base station ID from the input emergency signal, reads the address data of the wireless base station 62 corresponding to the base station ID from its own memory (not shown).

Next, the PHS service control station 11 displays a message indicating that an emergency has occurred and the address data on the service console 12. Thus, the observer recognizes that an emergency has occurred in the service area of the wireless base station 62 and immediately contacts the police.

As described above, according to the mobile communication system according to the above-described embodiment, since the emergency button 41 is provided, the fact that an emergency has occurred can be promptly notified to the police or the like by a simple operation. Notify related organizations.

As described above, one embodiment of the present invention has been described with reference to the drawings. However, the specific configuration example is not limited to the same embodiment, and a design change within a range not departing from the gist of the present invention. The present invention is also included in the present invention. For example,
In the mobile communication system according to the above-described embodiment, an example in which the PHS terminals 11 to 1n are used as the mobile communication terminals has been described. However, the present invention is not limited thereto. A terminal or a mobile wireless terminal may be used.

Further, in the mobile communication system according to the above-described embodiment, the service console 12 may be installed in a police station having jurisdiction over the building where the PHS service control station 11 is installed. In this case, the police can be more quickly notified that an emergency has occurred.

[0024]

As described above, according to the present invention, simply pressing the operating element notifies the monitoring person of the occurrence of an emergency by the notification device. The effect of being able to promptly notify the police and other related organizations is obtained.
