  Each base station is, for example, a base station of a cellular phone communication network or a PHS (Personal Handy phone System) communication network. When each base station can communicate with the mobile terminal 100, the base station can communicate information indicating that communication with the mobile terminal 100 is possible (for example, that the mobile terminal 100 is in the cell). Means for transmitting the cell information to the exchange 121 (communication enable information transmission means), means for transmitting the signal transmitted by the exchange 121 to the mobile terminal 100, and means for transmitting the signal transmitted by the mobile terminal 100 to the exchange 121 (signal Relay means).

  The switch 121 is, for example, a switch for a mobile phone communication network or a PHS communication network. The mobile terminal 100 and the communication terminal 110 are, for example, a mobile phone or a PHS terminal. In addition, the mobile terminal 100 has means for transmitting a response signal to the exchange 121 via each base station when a signal requesting a response is received from the exchange 121 via each base station.

  FIG. 2 is a block diagram illustrating a configuration example of the exchange 121. 2 includes an information management unit (storage unit) 131 that stores information, a location confirmation unit (location verification unit) 141 that transmits and receives signals to and from the mobile terminal 100 via each base station, and information from each base station. An area determination unit (area determination unit) 151 that receives the information, and a notification unit (notification unit) 161 that notifies the communication terminal 110 of the status of the mobile terminal 100.

  The information management unit 131 includes information indicating the mobile terminal 100 to be monitored, information indicating timing for confirming the status of the mobile terminal 100, information indicating the communication terminal 110 that is a notification destination of the status of the mobile terminal 100, Information indicating conditions for notifying the communication terminal 110 of the status of the mobile terminal 100 is stored.

  Note that the information management unit 131 responds to a request from the user of the communication terminal 110, information indicating the mobile terminal 100 to be monitored, information indicating the timing for confirming the status of the mobile terminal 100, and the status of the mobile terminal 100. Is stored (registered). The information indicating the communication terminal 110 that is the destination of the notification and the information indicating the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 are stored.

  For example, a mobile terminal monitoring system operating company or the like establishes a home page for registering information in the information management unit 131, and stores information input by the user of the communication terminal 110 in the information management unit 131. In addition, for example, a management company of the mobile terminal monitoring system opens a reception window for registering information in the information management unit 131, and the information notified by the user of the communication terminal 110 by telephone or the like is manually transmitted to the reception window. Is stored in the information management unit 131.

  The information indicating the mobile terminal 100 to be monitored is, for example, the telephone number of the mobile terminal 100 or the terminal ID. The information indicating the communication terminal 110 that is the notification destination of the status of the mobile terminal 100 is, for example, the telephone number of the communication terminal 110 or the terminal ID.

  The conditions for notifying the communication terminal 110 of the status of the mobile terminal 100 include, for example, that the mobile terminal 100 has moved out of a predetermined active range, and the timing at which the location confirmation unit 141 checks the status of the mobile terminal 100 ( For example, a response signal is not continuously received a predetermined number of times (for example, twice) with respect to a paging signal (calling signal, response request signal) transmitted at intervals of 5 minutes.

  A case where the mobile terminal 100 moves out of the predetermined active range will be described. The predetermined activity range is a range that the user requests for registration in advance, and corresponds to a cell with which the mobile terminal 100 can communicate. Specifically, for example, it refers to a range in which the mobile terminal 100 can communicate with the base station 122 or 123. Therefore, when the mobile terminal 100 moves from a range in which communication with the base station 122 or 123 can be performed to a range in which communication with the base station 124 can be performed, the mobile terminal 100 moves out of a predetermined active range. Therefore, the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is satisfied.

  When each base station can communicate with the mobile terminal, each base station transmits to the exchange 121 communication enable information indicating that communication with the mobile terminal can be performed. The area determination unit 151 receives communicable information transmitted from each base station. That is, when the base station with which the mobile terminal 100 communicates changes, the area determination unit 151 performs communication indicating that communication with the mobile terminal 100 is possible from the base station that newly communicates with the mobile terminal 100. Receive possible information.

  FIG. 3 shows that when the base station that communicates with the mobile terminal 100 is replaced, the area determination unit 151 can communicate with the mobile terminal 100 from the base station that newly communicates with the mobile terminal 100. It is explanatory drawing which shows the operation | movement which receives possible information.

  In the example shown in FIG. 3, the mobile terminal 100 moves from a range communicable with the base station 122 (in the cell of the base station 122) to a range communicable with the base station 123 (in the cell of the base station 123). The mobile station has moved from a range communicable with the station 123 to a range communicable with the base station 124 (within the cell of the base station 124). That is, the mobile terminal 100 is handed over from the base station 122 to the base station 123 and further handed over from the base station 123 to the base station 124 due to movement.

  When the mobile terminal 100 moves from a range communicable with the base station 122 (in the cell of the base station 122) to a range communicable with the base station 123 (in the cell of the base station 123), the area determination unit 151 From the base station 123, communicable information indicating that communication with the mobile terminal 100 is possible is received.

  When the mobile terminal 100 moves from a range communicable with the base station 123 (in the cell of the base station 123) to a range communicable with the base station 124 (in the cell of the base station 124), the area determination unit 151 The base station 124 receives communicable information indicating that communication with the mobile terminal 100 is possible.

  When the area determination unit 151 receives communicable information, the area determination unit 151 determines whether a condition for notifying the communication terminal 110 of the status of the mobile terminal 100 stored in the information management unit 131 is satisfied.

  Specifically, as illustrated in FIG. 3, the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is a condition that the mobile terminal 100 moves out of a predetermined active range, When the active range is a range in which communication with the base station 122 or 123 can be performed (that is, within the cell of the base station 122 or 123), the area determination unit 151 includes the base stations other than the base stations 122 and 123. When the communicable information is received from the mobile terminal 100, it is determined that the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 stored in the information management unit 131 is determined.

  Therefore, in the example illustrated in FIG. 3, the area determination unit 151 notifies the communication terminal 110 of the status of the mobile terminal 100 when receiving communicable information from the base station 124 that is a base station other than the base stations 122 and 123. It is determined that the conditions to be met are satisfied.

  When the area determination unit 151 determines that the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 stored in the information management unit 131 is satisfied, the area determination unit 151 notifies the notification unit 161 of the fact.

  The notification unit 161 notifies the communication terminal 110 via the base station 125 to the mobile terminal 100 when it is notified from the area determination unit 151 that the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is satisfied. Notifies that it has moved out of the predetermined range.

  In addition, the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is the paging signal (call signal) transmitted at the timing when the location confirmation unit 141 confirms the status of the mobile terminal 100 (for example, every 5 minutes). If the condition is that the response signal has not been received continuously for a predetermined number of times (for example, twice), the location confirming unit 141 is connected to the mobile terminal 100 stored in the information managing unit 131. A paging signal is transmitted to the mobile terminal 100 via each base station based on information indicating the timing for confirming the situation. Then, location checking section 141 receives a response to the paging signal from mobile terminal 100 via each base station.

  In addition, the location confirmation unit 141 satisfies a condition for notifying the communication terminal 110 of the status of the mobile terminal 100 when the response to the transmitted paging signal is not continuously received a predetermined number of times, and the mobile terminal 100 is located. It is determined that it is unknown, and a notification to that effect is sent to the notification unit 161.

  The notification unit 161 notifies the communication terminal 110 via the base station 125 that the mobile terminal 100 is unknown when the location confirmation unit 141 is notified that the mobile terminal 100 is unknown. .

  FIG. 4 is an explanatory diagram showing a case where the exchange 121 notifies the communication terminal 110 of the status of the mobile terminal 100.

  In the example shown in FIG. 4A, the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is out of the range in which the mobile terminal 100 can communicate with the base station 122 or 123 (that is, the base station 122 And out of 123 cells).

  As shown in FIG. 4A, since the mobile terminal 100 is located in a range in which communication is possible with the base station 124 (that is, in the cell of the base station 124), the base station 124 Is transmitted to the exchange 121.

  Since the area determination unit 151 has received the communicable information from the base station 124, which is a base station other than the base stations 122 and 123, the area determination unit 151 determines that the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is satisfied. Is notified to the notification unit 161.

  Then, the notification unit 161 notifies the communication terminal 110 via the base station 125 that the mobile terminal 100 has moved out of a predetermined range.

  In the example shown in FIG. 4B, the location confirmation unit 141 responds to the paging signal transmitted at the timing of confirming the status of the mobile terminal 100 (in the example shown in FIG. 4B, at an interval of 5 minutes). If the response signal is not received continuously for a predetermined number of times (twice in the example shown in FIG. 4B), the mobile terminal 100 determines that the location is unknown, and notifies the notification unit 161 to that effect. Notify

  Then, the notification unit 161 notifies the communication terminal 110 via the base station 125 that the mobile terminal 100 is unknown.

  The exchange 121 transmits a response request signal requesting a response from the mobile terminal 100 to the computer via the base station, receives a response signal for the response request signal from the mobile terminal 100 via the base station, and communicates with the communication terminal. 110, a location confirmation process for determining whether or not a predetermined condition for transmitting information indicating the status of the mobile terminal 100 is satisfied, and a communication terminal when the location confirmation process determines that the predetermined condition is satisfied A mobile terminal monitoring program for causing 110 to execute notification processing for transmitting information indicating the status of the mobile terminal 100 may be installed.

  In addition, when the base station is able to communicate with the mobile terminal 100, the exchange 121 receives and receives communicable information indicating that communication with the mobile terminal 100 is possible from the base station. Based on the communicable information, an area determination process for determining whether or not a predetermined condition for transmitting information indicating the status of the mobile terminal 100 to the communication terminal 110 is satisfied, and the area determination process satisfies the predetermined condition. A mobile terminal monitoring program for causing the communication terminal 110 to execute notification processing for transmitting information indicating the status of the mobile terminal 100 when it is determined that the mobile terminal 100 is present may be installed.

  The location confirmation unit 141, the area determination unit 151, and the notification unit 161 may be realized by a CPU that executes processing according to program control or a communication unit of a computer including the CPU.

  Next, the operation of the embodiment of the present invention will be described with reference to the drawings. FIG. 5 is an explanatory diagram showing the operation of the embodiment of the present invention.

  Here, a case where the communication terminal 110 requests registration is taken as an example. The user of the communication terminal 110, for example, information indicating the mobile terminal to be monitored and information indicating the timing of confirming the status of the mobile terminal to be monitored to the exchange 121 via the operating company of the mobile terminal monitoring system or the like. Requesting registration of information indicating a communication terminal that is a notification destination of the status of the mobile terminal to be monitored and information indicating a condition for notifying the status of the mobile terminal to be monitored to the communication terminal are requested. Note that the information indicating the condition for notifying the communication terminal of the status of the mobile terminal to be monitored includes information indicating the active range of the mobile terminal to be monitored.

  When the exchange 121 receives a request from the user of the communication terminal 110 via the base station 125, for example, a control unit (not shown) informs the information management unit 131 of information indicating the mobile terminal 100 to be monitored. Registration of information indicating the timing for confirming the status of the mobile terminal 100, information indicating the communication terminal 110 to which the status of the mobile terminal 100 is notified, and information indicating a condition for notifying the communication terminal 110 of the status of the mobile terminal 100 To do.

  In the example shown in FIG. 5, the monitoring target is the mobile terminal 100, the timing for confirming the status of the mobile terminal 100 is every 5 minutes, and the notification destination of the status of the mobile terminal 100 is the communication terminal 110. And that the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is that the mobile station 100 has moved out of the cell of the base station 122 or 123 (that is, the active range), and paging transmitted every 5 minutes The information management unit 131 registers (stores) that a response signal is not received twice consecutively for the signal.

  The location confirmation unit 141 transmits a paging signal to the mobile terminal 100 via the base station at intervals of 5 minutes based on the information stored in the information management unit 131. The location confirmation unit 141 receives a signal responding to the paging signal transmitted from the mobile terminal 100 via the base station.

  The location confirmation unit 141 counts the number of times that the signal responding to the paging signal is not received when the signal responding to the paging signal is not received after transmitting the paging signal.

  Then, the location confirmation unit 141 satisfies the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 when the signal responding to the paging signal is not received twice in succession, and the mobile terminal 100 is unknown. It determines that there is, and notifies the notification unit 161 to that effect.

  The notification unit 161 notifies the communication terminal 110 via the base station 125 that the mobile terminal 100 is unknown when the location confirmation unit 141 is notified that the mobile terminal 100 is unknown. .

  In addition, the mobile terminal 100 has moved from a range in which communication with the base station 122 (in the cell of the base station 122) to a range in which communication with the base station 123 (in the cell of the base station 123) is possible. In this case, the base station 123 transmits communicable information to the exchange 121.

  The area determination unit 151 receives the communicable information transmitted from the base station 123. Since the area determination unit 151 receives the communicable information from the base station 123, the area determination unit 151 determines that the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is not satisfied.

  When the mobile terminal 100 moves from a range where communication is possible with the base station 123 (in the cell of the base station 123) to a range where communication is possible with the base station 124 (in the cell of the base station 124) The base station 124 transmits the communicable information to the exchange 121.

  The area determination unit 151 receives the communicable information transmitted from the base station 124. Since area determination unit 151 has received communicable information from base stations other than base stations 122 and 123, area determination unit 151 determines that the condition for notifying communication terminal 110 of the status of mobile terminal 100 is satisfied.

  Then, the area determination unit 151 notifies the notification unit 161 that the mobile terminal 100 has moved out of the predetermined range.

  The notification unit 161 notifies the communication terminal 110 via the base station 125 that the mobile terminal 100 is out of the predetermined range when the area determination unit 151 notifies that the mobile terminal 100 has moved out of the predetermined range. Notify that it has moved.

  In the mobile terminal monitoring system according to the present embodiment, the battery of the mobile terminal 100 is removed, or the mobile terminal 100 is destroyed and broken down, so that the exchange 121 continuously transmits a response signal to the paging signal a predetermined number of times. If the mobile terminal 100 is not received, the exchange 121 can notify the communication terminal 110 that the mobile terminal 100 is unknown. Therefore, it is possible to immediately notify the user of the communication terminal 110 of the occurrence of an incident involving the user of the mobile terminal 100.

  Further, in the mobile terminal monitoring system of the present embodiment, when mobile terminal 100 moves out of a predetermined range, exchange 121 notifies communication terminal 110 that mobile terminal 100 has moved out of the predetermined range. . Therefore, it is possible to immediately notify the user of the communication terminal 110 of a kidnapping incident involving the user of the mobile terminal 100 or the occurrence of a lost child.

  Note that the information management unit 131 of the exchange 121 may change the conditions for notifying the communication terminal 110 of the status of the mobile terminal 100 according to the time in response to a request from the user of the communication terminal 110.

  Specifically, for example, in the condition for notifying the communication terminal 110 of the status of the mobile terminal 100, the predetermined active range is set as a cell of the base station 122 from 8 am to 3 pm, and from 3 pm A cell of the base station 123 is assumed until 8 am.

  Of the conditions for notifying the communication terminal 110 of the status of the mobile terminal 100, if the predetermined active range is changed according to the time, the mobile terminal 100 moves out of the predetermined active range according to the time. The status of the mobile terminal 100 can be notified to the communication terminal 110.

  Also, for example, the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is a case where a response signal to the paging signal is not received five times continuously from 8:00 am to 3:00 pm. From time to 8 am, it is assumed that no response signal to the paging signal is received.

  Further, for example, among the conditions for notifying the communication terminal 110 of the status of the mobile terminal 100, the timing for confirming the status of the mobile terminal 100 (ie, the interval at which the exchange 121 transmits the paging signal) is changed from 8:00 am Every 3 minutes is 3 minutes, and every 3 minutes from 3 pm to 8 am.

  In the case where the confirmation of the status of the mobile terminal 100 using the paging signal is changed according to the time, for example, during the daytime when it is difficult to get involved in the incident, the mobile terminal 100 has a longer transmission interval of the paging signal. Power consumption can be reduced. Further, at night when it is easy to get involved in an incident, the transmission interval of the paging signal is shortened so that the communication terminal 110 can be quickly notified of the status of the mobile terminal 100 or when there is no response to the paging signal, The status of the mobile terminal 100 can be notified to 110.

  That is, when the condition for notifying the communication terminal 110 of the status of the mobile terminal 100 is changed according to time, the change in the action range of the user of the mobile terminal 100 according to time or the time A condition for notifying the communication terminal 110 of the status of the mobile terminal 100 can be set based on the change in the occurrence frequency of the incident.

  In the present embodiment, the communication terminal 110 is assumed to be a mobile phone or the like. However, the communication terminal 110 is a computer connected to the Internet or a telephone connected to a public telephone line. Also good.

  The communication unit 161 of the exchange 121 may notify the communication terminal 110 of the status of the mobile terminal 100 via the Internet or a public telephone line.

  The communication terminal 110 is a computer connected to the Internet or a telephone connected to a public telephone line, and the communication unit 161 of the exchange 121 is connected to the communication terminal 110 via the Internet or public telephone line. When the communication terminal 110 is configured to notify the communication terminal 110, the communication terminal 110 can notify the communication terminal 110 of the status of the mobile terminal 100.

  Further, although the present embodiment has been described assuming that the mobile terminal 100 is a mobile phone or the like, the mobile terminal 100 has a function of receiving a paging signal transmitted from the exchange 121 via a base station, and a reception function. It is only necessary to have a function of transmitting a signal responding to the paging function to the exchange 121 via the base station, and it is not necessary to have a call function or the like.

  When the mobile terminal 100 is configured not to have a call function or the like, the mobile terminal 100 can be downsized or reduced in price.
