Description

  The present invention relates to an installation position movement detection system and a communication apparatus that detect and notify a movement of a communication device installed at a specific location when the communication device is moved beyond a certain allowable range from the specific location. It is.

  Conventionally, in order to detect the movement of a device at a remote location, the target device is equipped with a GPS (Global Positioning System) or the like, and the position information of the device is obtained by GPS, thereby determining the movement from the original installation location. (See Patent Document 1).

  In such a system, the initial installation position information of each target device is individually managed by the server device on the network, and then the server device acquires the current position information from the target device, and the initial installation position information It has been necessary to always determine the movement of the target device by comparing it with the current position. Further, the server device needs to determine whether the movement of the target device is within a certain allowable range in addition to the acquisition of the position information and the movement determination of the target device.

  Further, in order to acquire the position information of the device using GPS, the target device is always installed in a place where radio waves from GPS satellites can be received, and whether or not the target device is moving is periodically checked by the server device. It was necessary to judge.

  In femtocell services, etc. that make mobile phones more convenient in the home, mobile phones are used in the center of buildings where radio waves from GPS satellites can enter, rather than in the surrounding areas such as windows and entrances. It is assumed that there are many. For this reason, the effect of the service is halved in a system structure in which a service cannot be provided unless radio waves from GPS satellites can always be received.

JP 2008-310499 A

In the prior art, when the initial installation position information of each target device is managed by a server device, etc., and the current position information is acquired from all target devices and the movement determination of the target device is performed, the target device with almost no movement There is a problem in that much of the processing related to movement determination is wasted.
In addition, even when movement of a device within a certain range is allowed, it is necessary to perform movement determination on the server device side, and the processing related to movement determination is wasted for a target device that hardly moves. There was a point.
In addition, the conventional technique has a problem in that the load on the network and the server apparatus increases because the server apparatus needs to regularly acquire the position information of the target device regularly.

  Furthermore, in the prior art, when GPS is used to acquire the position information of the target device, the position information cannot be acquired in a place where radio waves from GPS satellites do not reach, and thus movement of the device within the building is permitted. Even in this case, there is a problem that information for movement determination cannot be obtained. When the target device is a communication device such as a femtocell service, when the current location information cannot be acquired, the server device side on the network tries to stop the service, so the reception state of the radio wave from the GPS satellite is temporarily There was a possibility that the service would stop when it got worse.

  The present invention has been made to solve the above-described problem, and can reduce the load on the network and the server device, and relax the restriction on the installation of the communication device when the GPS is used to acquire the position information. It is an object of the present invention to provide an installation position movement detection system and a communication device that can perform communication.

The installation position movement detection system according to the present invention includes a communication device and a server device on a network that monitors the movement of the communication device, and the communication device acquires current position information of the device by GPS. Position information acquisition means, movement detection means for detecting movement of the own apparatus, and original position information registration means for registering position information acquired by the position information acquisition means before the use of the communication service as original position information in the server device Current position information storage means for storing position information acquired by the position information acquisition means as current position information when the power is turned on again or when the movement detection means detects the movement of the own device; The original position information is acquired from the server device when the device is turned on again or when the movement detecting means detects the movement of the own device. Original position information acquisition means, and when the power is turned on again or when the movement detection means detects the movement of the own apparatus, the movement of the own apparatus is predetermined based on the original position information and the current position information. And determining means for determining whether or not it is within the allowable range .
The installation position movement detection system according to the present invention further acquires position information by the position information acquisition means when the determination means determines that the movement of the apparatus is out of an allowable range or when the power is turned on again. If not, the communication service being provided is stopped, and when the movement of the own apparatus is determined to be within the allowable range, or when the movement detection means detects the movement of the own apparatus, the position information acquisition means If the position information cannot be acquired, the communication service control means for continuing the communication service, and the movement of the own apparatus is out of the allowable range when the determination means determines that the movement of the own apparatus is out of the allowable range. And a notification means for notifying the server device of the fact.

Further, in one configuration example of the installation position movement detection system according to the present invention, the position information acquisition unit acquires the current position information of the own device at regular time intervals, and the original position information acquisition unit performs the regular position information acquisition at regular time intervals. The original position information is acquired, and the determination unit determines whether the movement of the own device is within a predetermined allowable range at regular intervals, and the communication service control unit allows the movement of the own device by the determination unit. When it is determined that it is out of range, the communication service is stopped, and when it is determined that the movement of the own device is within the allowable range or when the current position information cannot be acquired at the time of acquisition at regular intervals. The communication service is continued.
Moreover, in one configuration example of the installation position movement detection system of the present invention, the communication device further includes original position information storage means for storing the original position information, and the original position information acquisition means includes the original position information. When the original position information is stored in the storage means, the original position information is acquired from the original position information storage means instead of the server device.
Further, in one configuration example of the installation position movement detection system of the present invention, the communication service control means stops the communication service by notifying a network device when the communication service is stopped. To do.
In the configuration example of the installation position movement detection system according to the present invention, the notification unit notifies the network device of the determination result of the determination unit at least once when the original position information is acquired. It is what.

In addition, the communication apparatus of the present invention includes a position information acquisition unit that acquires current position information of the own device by GPS, a movement detection unit that detects movement of the own device, and the position information acquisition unit before the start of communication service use. Original position information registering means for registering the position information acquired in the above as original position information in a server device on the network, and when the power is turned on again or when the movement detecting means detects the movement of the own apparatus, Current position information storage means for storing position information acquired by the information acquisition means as current position information, and when the power is turned on again or when the movement detection means detects the movement of the own apparatus, Original position information acquisition means for acquiring original position information, and when the power is turned on again or when the movement detection means detects the movement of its own device. Occasionally, on the basis of the original location information and the current position information, the movement of the apparatus is characterized in further comprising a determination means for determining whether within a predetermined tolerance.
In addition, the communication device of the present invention could not acquire the position information by the position information acquisition unit when the determination unit determines that the movement of the own device is out of the allowable range or when the power is turned on again. In the case, the communication service being provided is stopped, and when the movement of the own apparatus is determined to be within the allowable range, or when the movement detection means detects the movement of the own apparatus, the position information acquisition means If the information cannot be obtained, the communication service control means for continuing the communication service, and the movement of the own apparatus is out of the allowable range when the determination means determines that the movement of the own apparatus is out of the allowable range. And a notification means for notifying the server apparatus of the above.

  According to the present invention, when the power is turned on again or when the movement of the communication device is detected, it is determined whether the movement of the communication device is within a predetermined allowable range, and the movement of the communication device is determined to be out of the allowable range. If the current position information cannot be obtained when the power is turned on again, the communication service is stopped and the movement of the communication device is determined to be within the allowable range or the movement of the communication device is detected. If the current position information could not be acquired, the communication service is continued, and if it is determined that the movement of the communication device is out of the allowable range, the server device indicates that the movement of the communication device is out of the allowable range. Thus, unnecessary traffic is not frequently exchanged between the communication device and the server device, and it is not necessary to frequently determine movement in the communication device or the server device. As a result, according to the present invention, the load on the network and the server device can be reduced. Also, in the present invention, when the communication device is within the allowable movement range when the power is turned on, and then the communication device is moved while the power is on, the current position information cannot be acquired. Since the service is continued, the communication device can be temporarily installed in a place where radio waves from GPS satellites cannot be received, and restrictions on the installation of the communication device can be relaxed.

  Further, in the present invention, when the communication device is moved beyond the allowable range by acquiring the current position information at regular time intervals, the communication device can be received at the timing when the radio wave from the GPS satellite can be received during the movement. It is possible to determine whether or not the movement is within an allowable range, and it is possible to determine whether or not to provide the service.

  In the present invention, when the original position information is stored in the original position information storage means, the original position information is acquired from the original position information storage means instead of the server device. The load on the apparatus can be further reduced.

  In the present invention, when the communication service is stopped, the network service can be stopped by notifying the network device.

  In the present invention, when the original position information is acquired, the network device side can determine whether or not to provide the communication service by notifying the network device of the determination result of the determination means at least once. The communication service can be stopped if there is any abnormality in the network.

[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a communication device of an installation position movement detection system according to a first embodiment of the present invention. The communication device 1 is connected to an information acquisition device 4 that is a server device that monitors movement of the communication device 1 via a network. In the installation position movement detection system of the present embodiment, when the communication apparatus itself detects that the communication apparatus 1 has moved beyond the allowable range, the information acquisition apparatus 4 is notified. Thereby, the information acquisition device 4 can recognize the movement of the communication device 1.

  The communication device 1 includes a movement detection device 2 and a GPS antenna 3. The movement detection device 2 includes a movement detection unit 20 that detects movement of the communication device 1 using a vibration sensor, a geomagnetic sensor, an acceleration sensor, and the like, a time measurement unit 21 that measures time, and current position information of the communication device 1 using GPS. The position information acquisition unit 22 for acquiring the position information, the position information storage unit 23 for storing the current position information acquired by the position information acquisition unit 22, and the initial setting of the communication device 1 from the original position information storage unit or the information acquisition device 4 described later. The original position information acquisition unit 24 that acquires the original position information, the original position information storage unit 25 that stores the original position information, and the information acquisition device 4 are notified of the original position information, and the communication device 1 moves. For notifying that the user has moved out of the permissible range, and the original position information stored in the original position information storage unit 25. Based on the current position information stored in the position information storage unit 23 and the movement distance calculation unit 27 that calculates the distance between the original position of the communication device 1 and the current position, and communication based on the calculation result of the movement distance calculation unit 27 Providing a communication service based on whether the movement of the apparatus 1 is within the allowable range, the determination result of the movement range determination unit 28, and whether or not the current position information can be acquired by the position information acquisition unit 22. A communication service control unit 29 for determining

  The notification unit 26 constitutes original position information registration means for registering original position information in the information acquisition device 4. The movement distance calculation unit 27 and the movement range determination unit 28 constitute a determination unit that determines whether the movement of the communication device 1 is within a predetermined allowable range.

  FIG. 2 is a block diagram showing the configuration of the information acquisition device 4. The information acquisition device 4 includes a reception unit 40 that receives position information and the like sent from the communication device 1, a transmission unit 41 that transmits information to the communication device 1, and a storage unit 42 that stores the position information and the like of the communication device 1. And a control unit 43 that controls the entire information acquisition apparatus.

  Next, the operation of the installation position movement detection system when performing the initial setting of the communication device 1 will be described with reference to FIGS. First, when the communication device 1 is turned on (step S200 in FIG. 4) and an initial registration instruction is issued from the communication device body (step S201), the position information acquisition unit 22 of the movement detection device 2 uses GPS to Position information is acquired (step S100 in FIG. 3, step S202 in FIG. 4). The position information acquisition unit 22 stores the acquired position information as original position information in the original position information storage unit 25 (steps S101 and S203).

  Subsequently, the notification unit 26 of the movement detection device 2 notifies the information acquisition device 4 of the position information acquired by the position information acquisition unit 22 as original position information (steps S102 and S204). At this time, the notification unit 26 transmits the device-specific information unique to the communication device 1 added to the original position information. The device unique information includes, for example, a MAC (Media Access Control) address and the serial number of the communication device 1.

  The reception unit 40 of the information acquisition device 4 passes the original position information and the device specific information received from the movement detection device 2 to the control unit 43. The control unit 43 registers the original position information and the device specific information in the storage unit 42 in association with each other (step S205 in FIG. 4). And the transmission part 42 of the information acquisition apparatus 4 transmits the response which shows registration completion to the movement detection apparatus 2 after completion of registration of original position information (step S206).

  When the notification unit 26 of the movement detection device 2 receives the response from the information acquisition device 4 and recognizes that the registration of the original position information is completed (YES in step S103 in FIG. 3), the communication service control unit confirms the registration completion. 29 is notified. In response to this notification, the communication service control unit 29 starts a communication service between the communication apparatus main body and the network (steps S104 and S207).

  The operation at the time of initial setting of the communication device 1 is thus completed. Note that if the location information cannot be acquired in steps S100 and S202, the communication service cannot be started. Therefore, the initial position of the communication device 1 needs to be a position where radio waves from GPS satellites can be received.

  Next, the operation of the installation position movement detection system when the power of the communication apparatus 1 is once turned off and then turned on will be described with reference to FIGS. When the communication apparatus 1 is turned on again (step S400 in FIG. 6) and the communication apparatus main body makes an inquiry about whether or not the service can be started (step S401), the position information acquisition unit 22 of the movement detection apparatus 2 detects the position information of the own apparatus. (Step S300 in FIG. 5, Step S402 in FIG. 6). The position information acquisition unit 22 stores the acquired position information in the position information storage unit 23 (steps S301 and S403).

  If the location information acquisition unit 22 cannot acquire location information (NO in step S302 in FIG. 5), the communication service control unit 29 of the movement detection device 2 determines that the communication service between the communication device body and the network is not possible, The communication service being provided is stopped (step S309). Therefore, as in the case of the initial setting, the position of the communication device 1 when the power is turned on again needs to be a position where radio waves from GPS satellites can be received.

  On the other hand, the original position information acquisition unit 24 of the movement detection device 2 checks whether or not the original position information is stored in the original position information storage unit 25 (step S404 in FIG. 6), and the original position information is not stored. The device specific information of the communication device 1 is transmitted to the information acquisition device 4, and the original position information is inquired (step S405). When the original position information storage unit 25 is a volatile memory, since the original position information is not registered in the original position information storage unit 25 when the power is turned on again, the information acquisition device 4 is inquired.

  The reception unit 40 of the information acquisition device 4 passes the device specific information received from the movement detection device 2 to the control unit 43. The control unit 43 refers to the storage unit 42, acquires original position information corresponding to the device specific information from the storage unit 42, and passes this original position information to the transmission unit 41 (step S406 in FIG. 6). The transmission unit 41 transmits the original position information received from the control unit 43 to the movement detection device 2 (step S407).

When the original position information acquisition unit 24 of the movement detection device 2 receives the original position information from the information acquisition device 4 (step S303 in FIG. 5), the original position information storage unit 25 stores the original position information (steps S304 and S408). ).
Next, the movement distance calculation unit 27 of the movement detection device 2 can acquire the current position information by the position information acquisition unit 22 and can acquire the original position information by the original position information acquisition unit 24. In this case, the distance between the original position of the device itself and the current position is calculated (step S305).

The movement range determination unit 28 of the movement detection apparatus 2 compares the movement distance calculated by the movement distance calculation unit 27 with a predetermined allowable value, and determines whether the movement of the own apparatus is within the allowable range (steps S306 and S409). ). The movement range determination unit 28 determines that the movement of the own apparatus is within the allowable range when the movement distance is equal to or less than the allowable value.
The communication service control unit 29 of the movement detection device 2 starts communication service between the communication device main body and the network when the movement range determination unit 28 determines that the movement of the own device is within the allowable range (steps S307 and S410). .

Further, when the movement distance exceeds the allowable value, the movement range determination unit 28 determines that the movement of the own device is out of the allowable range. In this case, the notification unit 26 of the movement detection device 2 notifies the information acquisition device 4 that the movement of the own device is outside the allowable range (step S308).
Then, if the movement range determination unit 28 determines that the movement of the own device is out of the allowable range, the communication service control unit 29 stops the communication service between the communication apparatus main body and the network (steps S309 and S410).
Thus, the operation when the communication apparatus 1 is turned on again is completed.

  Next, the operation of the installation position movement detection system when the movement of the communication device 1 is detected will be described with reference to FIG. 7, FIG. 8, and FIG. 8 shows the operation when the position information acquisition unit 22 can acquire the position information, and FIG. 9 shows the operation when the position information acquisition unit 22 cannot acquire the position information.

  When the movement detection unit 20 detects the movement of the own device (step S600 in FIG. 8), the position information acquisition unit 22 of the movement detection device 2 acquires the position information of the own device (step S500 in FIG. 7, step in FIG. 8). S601). The position information acquisition unit 22 stores the acquired position information in the position information storage unit 23 (steps S501 and S602).

  If the position information acquisition unit 22 cannot acquire the position information (NO in step S502 of FIG. 7), the movement detection device 2 ends the movement detection sequence without performing any processing as shown in FIG. To do. In this case, the communication service control unit 29 of the movement detection device 2 continues the communication service between the communication device main body and the network (step S507).

The processing in steps S603, S604, S605, and S606 in FIG. 8 is the same as steps S404, S405, S406, and S407 in FIG.
When the original position information acquisition unit 24 of the movement detection device 2 receives the original position information from the information acquisition device 4 (step S503), the original position information storage unit 25 stores the original position information (steps S504 and S607). If the original position information is registered in the original position information storage unit 25 when the original position information is confirmed in step S603, the original position information may be acquired from the original position information storage unit 25. There is no need to newly acquire original position information from the acquisition device 4.

The processing in step S505 in FIG. 7 is the same as step S305 in FIG. The movement range determination unit 28 of the movement detection device 2 compares the movement distance calculated by the movement distance calculation unit 27 with a predetermined allowable value, and determines whether the movement of the own device is within the allowable range (steps S506 and S608). ).
The communication service control unit 29 of the movement detection device 2 continues the communication service between the communication device main body and the network when the movement range determination unit 28 determines that the movement of the own device is within the allowable range (steps S507 and S609). .

The notification unit 26 of the movement detection device 2 notifies the information acquisition device 4 that the movement of the own device is out of the allowable range when the movement range determination unit 28 determines that the movement of the own device is out of the allowable range. (Step S508). And the communication service control part 29 stops the communication service of a communication apparatus main body and a network (step S509, S609).
The operation at the time of detecting the movement of the communication device 1 is thus completed.

  Next, the periodic check operation at regular intervals of the communication device 1 will be described with reference to FIGS. The time measuring unit 21 of the movement detection device 2 performs time measurement. The position information acquisition unit 22 of the movement detection device 2 acquires the position information of its own device (step S700 in FIG. 10, step S801 in FIG. 11) every time a certain time has elapsed (step S800 in FIG. 11). The position information acquisition unit 22 stores the acquired position information in the position information storage unit 23 (steps S701 and S802).

  If the location information acquisition unit 22 cannot acquire the location information (NO in step S702 in FIG. 10), the communication service control unit 29 of the movement detection device 2 continues the communication service between the communication device body and the network (step S707). ).

The processes in steps S803, S804, S805, and S806 in FIG. 11 are the same as steps S404, S405, S406, and S407 in FIG. 6, respectively.
When the original position information acquisition unit 24 of the movement detection device 2 receives the original position information from the information acquisition device 4 (step S703), the original position information is stored in the original position information storage unit 25 (steps S704 and S807).

The processing in step S705 in FIG. 10 is the same as step S305 in FIG. The movement range determination unit 28 of the movement detection device 2 determines whether or not the movement of the own device is within the allowable range (steps S706 and S808).
The communication service control unit 29 of the movement detection device 2 continues the communication service between the communication device main body and the network when the movement range determination unit 28 determines that the movement of the own device is within the allowable range (steps S707 and S809). .

The notification unit 26 of the movement detection device 2 notifies the information acquisition device 4 that the movement of the own device is out of the allowable range when the movement range determination unit 28 determines that the movement of the own device is out of the allowable range. (Step S708). And the communication service control part 29 stops the communication service of a communication apparatus main body and a network (step S709, S809).
The periodic check operation as described above is performed at regular intervals. In the present embodiment, operations at the time of initial setting, power-on, and movement detection are the main operations, and these operations are intended to reduce the load on the network and the load on the server device. The periodic check operation is an operation for dealing with a case where the original position information in the movement detection device 2 has been lost for some reason.

  FIG. 12 is a network configuration diagram showing a specific application example of the present embodiment. Here, a case where the communication apparatus 1 is a femtocell base station is shown. The communication device 1 is installed in the subscriber's house 5 and connected to the IP network 8 via the broadband router 7. An information acquisition device (premises server device) 4 is installed in the IP network 8. In the mobile phone network 9, a base station controller (RNC: Radio Network Controller) 10 and a base station 11 are installed. The communication device 1 provides a communication service for connecting a subscriber's mobile phone 6 and a call partner's mobile phone 12 via a broadband router 7, an IP network 8, and a mobile phone network 9. Alternatively, the communication device 1 provides a communication service for connecting the mobile phone 6 and the phone 14 via the broadband router 7, the IP network 8, and the fixed telephone network 13.

  In a system that provides such a communication service, it is necessary to install the communication device 1 at a position where radio waves from GPS satellites can be received as described above when the communication device 1 is initially set and when the power is turned on again. When the communication device 1 is powered on, for example, when it is moved out of the allowable movement range by the subscriber, the communication service is stopped. On the other hand, when the communication device 1 is moved to a place where the radio wave from the GPS satellite cannot be received with the power on, the communication service is continued in the present embodiment, so that the subscriber continues the communication service. Can receive.

  FIG. 13 is a diagram for explaining service continuity according to the present embodiment. In FIG. 13, reference numeral 100 denotes an allowable range of movement of the communication apparatus 1, and 101 denotes a satellite radio wave unreceivable area where radio waves from GPS satellites cannot be received. Reference numeral 102 denotes a case where the communication apparatus 1 moves to the satellite radio wave unreceivable area 101 while the power is off. In the case of 102, even if the communication apparatus 1 is turned on after moving to the satellite radio wave unreceivable area 101, the communication service cannot be started. In FIG. 13, this state is represented by “x” marks. Reference numeral 103 denotes a case where the communication apparatus 1 moves out of the allowable range 100 while the power is off. In the case of 103, the communication service cannot be started. Reference numerals 104 and 105 denote cases where the communication apparatus 1 moves from the subscriber house 5 to another subscriber house 5a with the power off. However, since the subscriber house 5a is outside the allowable range 100, these 104 , 105, the communication service cannot be started.

  Reference numeral 106 denotes a case where the communication apparatus 1 moves outside the allowable range 100 while the power is on. In the case of 106, the communication service is stopped. Reference numeral 107 denotes a case where the communication apparatus 1 moves out of the subscriber house 5 while the power is on, and reference numeral 108 denotes a case where the communication apparatus 1 moves inside the subscriber house 5 while the power is on. In both cases 107 and 108, since the communication apparatus 1 moves within the allowable range 100, the communication service is continued. In FIG. 13, this state is indicated by “◯”. Reference numeral 109 denotes a case where the communication apparatus 1 moves to the satellite radio wave unreceivable area 101 while the power is on. In the case of 109, the communication service is continued.

  As described above, in the present embodiment, the communication device 1 is moved when the power of the communication device 1 is turned on again, unlike the conventional technique in which position information is always periodically acquired to detect movement. Sometimes communicated with the information acquisition device 4 to acquire original position information from the information acquisition device 4 and determine whether or not the communication device 1 has moved beyond the allowable range. Wasteful traffic is not frequently exchanged with the device 4, and it is not necessary to frequently make a movement determination in the communication device 1 or the information acquisition device 4. As a result, in the present embodiment, when the information acquisition device 4 monitors the movement of the communication device 1, the load on the network and the information acquisition device 4 can be reduced.

  Further, in the present embodiment, the communication device 1 is within the allowable movement range when the power is turned on, and then the communication device 1 is moved in a state where the power is on, and the current position information cannot be acquired. In this case, it is assumed that the communication device 1 is within the allowable range, and the communication service being provided is continued. Thereby, in this Embodiment, when using GPS which uses the electromagnetic wave from a satellite for acquisition of the current position information, the communication device 1 can be temporarily installed in a place where the electric wave from the GPS satellite cannot be received. It becomes possible and the restriction | limiting about installation of the communication apparatus 1 can be eased.

  Furthermore, in the present embodiment, when the communication device 1 is moved beyond the allowable range by acquiring the current position information at regular time intervals, the radio wave from the GPS satellite is moved during the movement. It is possible to determine whether or not the movement of the communication device 1 is within an allowable range at the timing when the communication can be received, and to determine whether or not to provide the service.
