The present invention relates to a movement detection system, a gateway device, a movement detection device, a movement detection method, and a movement detection program.

It is expected that it will be difficult to maintain fixed-line telephone services in mountainous areas and remote islands. Therefore, in Non-Patent Document 1, it is considered to provide a service (wireless fixed telephone service) equivalent to a conventional fixed telephone service using a mobile communication network of a mobile communication carrier.

A wireless fixed telephone service is realized by connecting an RG (Residential Gateway) equipped with a SIM (Subscriber Identity Module) to a fixed telephone. Even with wireless fixed-line telephone services, there is a possibility that 0ABJ numbers for fixed-line telephones will be used in the same way as with conventional fixed-line telephone services, so it is necessary to meet the usage conditions for 0ABJ numbers described in Non-Patent Document 2. . In order to satisfy one of the usage conditions, which is the condition for ensuring geographical identification, fixed telephones and RGs need to be fixedly installed in a predetermined area like conventional fixed telephones.

As described above, fixed telephones and RGs must be fixedly installed in a predetermined section (address registered at the time of contract, such as the user's home, office, etc.) in the same way as conventional fixed telephones.

However, since the RG can be wirelessly connected as long as it is within the range of radio waves of the radio base station of the mobile communication network, there is a risk that the fixed telephone and RG will move to a location other than the designated area. For example, there is a possibility that usage patterns and situations that are unthinkable for conventional fixed-line telephones, such as use outside the home or theft, may occur, and there is a possibility that the usage conditions of the 0ABJ number will be violated.

Also, if the landline phone and RG move, it may not be possible to obtain the position with the GPS (Global Positioning System) indoors such as in the office, so it is not possible to identify the position after the move. As a result, even if an emergency call is sent from a landline phone after moving, the location cannot be specified, and the registered address at the time of contract is notified to the administrative agency, which may delay the arrival of the fire engine or the like.

[Summary of Invention]
As described above, even a wireless landline phone connected to a landline phone with a SIM-equipped RG must be fixedly installed in a predetermined area like a conventional landline phone in order to meet the conditions for using the 0ABJ number. . In addition, location information is usually grasped by GPS or location registration to the mobile communication network, but it may be difficult to obtain location information by GPS indoors, and location management of landline phones is the responsibility of the mobile communication carrier. Instead, it is necessary for the fixed communication carrier to detect the location change of the wireless fixed telephone based on means other than GPS and location registration.

Therefore, the present invention introduces a sensor in the RG to detect movement of the wireless fixed telephone, and introduces a movement detection device in the fixed communication network of the fixed communication operator.

If the result of the analysis by the data analysis device 2 is that the measurement data regularly or irregularly measured by the wireless fixed telephone 1 (the sensor 122 of the RG 12) changes, the detection unit 31 determines that the wireless fixed telephone 1 has moved. and if the measured data does not change, the wireless fixed telephone 1 has the function of detecting no movement.

The mobile communication network D naturally includes existing devices (base stations, base station controllers, SIM information management devices, etc.) that make up the mobile communication network (wireless communication network). The radio wave control device 4 may be configured inside the existing device, or may be configured as a single device.

[Operation of mobile communication system]
FIG. 2 is a sequence diagram showing movement detection processing of the mobile communication system. In this processing example, the RG 12 of the wireless fixed telephone 1 is equipped with one or more sensors 122 selected from an air pressure sensor, an air temperature sensor, and an acceleration sensor, and the wireless fixed telephone 1 is installed based on the measurement data of the sensor 122. Detect location changes.

[Atmospheric pressure sensor]
A case where the RG 12 is equipped with an atmospheric pressure sensor will be described. Since the wireless fixed telephone 1 does not move in principle, the difference between the atmospheric pressure measured by the atmospheric pressure sensor of the RG 12 and the atmospheric pressure measured at the reference point does not change significantly. Therefore, when a large change in air pressure difference is detected, it is suspected that the wireless fixed telephone 1 is moving.

Step S1;
An air pressure sensor 122 in RG 12 continuously measures air pressure. The recording unit 123 acquires the atmospheric pressure measured by the atmospheric pressure sensor 122, acquires the atmospheric pressure measured by the atmospheric pressure sensor of the nearby weather observation device 5 at the same timing, and periodically records the difference between the two acquired atmospheric pressures. do. Further, when there is another user using the wireless fixed telephone service in the vicinity, the recording unit 123 acquires the atmospheric pressure measured by the atmospheric pressure sensor of the RG 12' of the other user at the same timing. The difference from the atmospheric pressure measured by the atmospheric pressure sensor 122 is periodically recorded.

Step S2;
The transmission unit 125 of the RG 12 periodically transfers the recorded atmospheric pressure difference to the data analysis device 2 via the mobile communication network D and the Internet E. Note that one or both records of the difference between the two pressures may be used depending on the presence or absence of the weather-observing device 5 or other user's RG 12'. Even if both the weather-observing device 5 and another user's RG 12' are present, only one record may be selectively used.

Step S3;
The data analysis device 2 periodically receives the difference in atmospheric pressure transmitted from the RG 12 and determines whether the received difference in atmospheric pressure has changed significantly. For example, if the received difference in atmospheric pressure exceeds the threshold, the data analysis device 2 determines that the difference in atmospheric pressure has changed significantly, and if the received difference in atmospheric pressure does not exceed the threshold, the difference in atmospheric pressure has changed significantly. judge not.

Step S4;
The data analysis device 2 transmits the determination result of the received air pressure difference to the movement detection device 3 .

Step S5;
When it is determined that the air pressure difference has changed significantly, the detection unit 31 of the movement detection device 3 determines that the wireless fixed telephone 1 has moved and detects the movement of the wireless fixed telephone 1 . On the other hand, if the detection unit 31 determines that the atmospheric pressure difference has not changed significantly, it considers that the wireless fixed telephone 1 has not moved. When the movement of the wireless fixed telephone 1 is detected, the fixed communication carrier cooperates with the mobile communication carrier to suspend the use of the wireless fixed telephone service by the wireless fixed telephone 1 thereafter.

Step S6;
When the movement of the wireless fixed telephone 1 is detected, the stopping unit 32 of the movement detection device 3 stops the use of radio waves of the mobile communication network D by the wireless fixed telephone 1 using the SIM information of the wireless fixed telephone 1. and transmits the usage suspension command to the radio wave control device 4 of the mobile communication network D.

Step S7;
When the radio wave control device 4 receives a command to stop using radio waves from the movement detection device 3, the radio wave control device 4 uses the SIM information of the wireless fixed phone 1 to stop the use of the radio waves of the mobile communication network D by the wireless fixed phone 1. . After that, the RG 12 of the wireless fixed telephone 1 cannot be wirelessly connected to the mobile communication network D. The fixed telephone 11 cannot use the wireless fixed telephone service provided through the mobile communication network D.

[Temperature sensor]
A case where an air temperature sensor is mounted on the RG 12 will be described. There are multiple rooms in an office building, and the temperature in each room changes characteristically along the time axis. For example, in an office, the temperature is maintained at about 25° C. during working hours, and after working hours, the air conditioning is turned off and the temperature changes to a value close to the outside temperature. In the server room, the temperature changes such that it is kept at about 28°C for 24 hours. Therefore, if the temperature change pattern in each room is different from the normal temperature change pattern (when the wireless fixed phone 1 is not moving), the movement of the wireless fixed phone 1 is suspected.

Step S1';
An air temperature sensor 122 in RG 12 continuously measures air temperature. The recording unit 123 acquires the temperature measured by the temperature sensor 122 and records daily temperature change patterns. In addition, when there is another user using the wireless fixed telephone service nearby, such as another floor in the same building, the recording unit 123 stores the temperature measured by the temperature sensor of the RG 12' of the other user. The difference from the temperature measured by the temperature sensor 122 of the RG 12 at the same timing is periodically recorded.

Step S2';
The transmission unit 125 of the RG 12 periodically sends the recorded temperature change pattern and temperature difference to the data analysis device 2 via the mobile communication network D and the Internet E. FIG.

Step S3';
The data analysis device 2 periodically receives the temperature change pattern and temperature difference transmitted from the RG 12, and determines whether the temperature change pattern has changed significantly and whether the received temperature difference has changed significantly. judge. For example, when the received temperature change pattern (first pattern) is significantly different from the normal temperature change pattern (second pattern), the data analysis device 2 determines that the temperature change pattern has changed significantly, and the first pattern is the second pattern. If the two patterns are not significantly different, it is determined that the temperature change pattern has not changed significantly. If the received temperature difference exceeds the threshold, the data analysis device 2 determines that the temperature difference has changed significantly, and if the received temperature difference does not exceed the threshold, the temperature difference has changed significantly. judge not.

As a method for determining a large change in the temperature change pattern, for example, whether or not the difference in average temperature between the first pattern and the second pattern exceeds a threshold, the maximum temperature of the first pattern is the maximum temperature of the second pattern. It is determined by whether or not the temperature exceeds the temperature, and whether or not the lowest temperature of the first pattern is lower than the lowest temperature of the second pattern.

Step S4';
The data analysis device 2 transmits the determination result of the temperature change pattern and the determination result of the temperature difference to the movement detection device 3 .

Step S5';
When it is determined that the temperature change pattern has changed significantly, the detection unit 31 of the movement detection device 3 determines that the wireless fixed telephone 1 has moved and detects the movement of the wireless fixed telephone 1 . However, even in this case, if a similar change is observed in the RG 12' of other nearby users, it is highly possible that the temperature has changed due to a disaster such as a power outage within the same area. Therefore, even if it is determined that the temperature change pattern has changed significantly, the detection unit 31 determines that the wireless fixed telephone 1 has not moved if it is determined that the difference in temperature has not changed significantly. Consider. When the movement of the wireless fixed telephone 1 is detected, the fixed communication carrier cooperates with the mobile communication carrier to suspend the use of the wireless fixed telephone service by the wireless fixed telephone 1 thereafter.

Step S6', Step S7';
This is the same as steps S6 and S7 described above.

[Acceleration sensor]
A case where an acceleration sensor is mounted on the RG 12 will be described. Since the wireless fixed telephone 1 does not move in principle, no acceleration is detected. Therefore, the movement of the wireless fixed telephone 1 is suspected when acceleration is detected.

Step S1'';
Acceleration sensor 122 of RG 12 continuously measures acceleration. The recording unit 123 periodically acquires and records the acceleration (first acceleration) measured by the acceleration sensor 122 . In addition, when there is another user using the wireless fixed telephone service nearby, the recording unit 123 records the acceleration (second acceleration) measured by the acceleration sensor of the RG 12' of the other user at the same timing. Get and record.

Step S2'';
The transmission unit 125 of the RG 12 periodically transfers the recorded first acceleration and second acceleration to the data analysis device 2 via the mobile communication network D and the Internet E.

Step S3'';
The data analysis device 2 periodically receives the first acceleration and the second acceleration transmitted from the RG 12, and determines whether the first acceleration has changed significantly and whether the difference in the second acceleration has changed significantly. judge. For example, if the received first acceleration exceeds the threshold, the data analysis device 2 determines that the first acceleration has changed significantly, and if the received first acceleration does not exceed the threshold, the data analysis device 2 determines that the first acceleration has changed significantly. judge not. The data analysis device 2 similarly determines the second acceleration.

Step S4'';
The data analysis device 2 transmits the determination result of the first acceleration and the determination result of the second acceleration to the movement detection device 3 .

Step S5'';
When it is determined that the first acceleration has changed significantly, the detection unit 31 of the movement detection device 3 determines that the wireless fixed telephone 1 has moved and detects the movement of the wireless fixed telephone 1 . However, even in this case, if a similar change (equivalent acceleration change at the same time) is observed in the RG 12' of other nearby users, it is possible that the acceleration change due to a disaster such as an earthquake in the same area It is also considered highly possible. Therefore, even if it is determined that the first acceleration has changed significantly, the detection unit 31 determines that the wireless fixed telephone 1 has not moved if it is determined that the second acceleration has also changed significantly. . When the movement of the wireless fixed telephone 1 is detected, the fixed communication carrier cooperates with the mobile communication carrier to suspend the use of the wireless fixed telephone service by the wireless fixed telephone 1 thereafter.

Step S6'', Step S7'';
This is the same as steps S6 and S7 described above.

It should be noted that when an acceleration sensor is used, there is a high possibility that the movement of the wireless fixed telephone 1 will be detected even when it moves within the user's home. Movement within the user's house is movement within a predetermined section, and movement should not be detected. Therefore, when an acceleration sensor is used, it is desirable to use it together with an atmospheric pressure sensor or an air temperature sensor. Alternatively, the movement distance may be roughly estimated by measuring the time when the acceleration is detected, and the magnitude of the movement distance may be compared with the width of the general user's house.

[Modification 1]
It is also possible to arbitrarily combine the above three operation patterns. The three operation patterns are applicable not only to specific types of sensors but also to other types of sensors for specific operation patterns. For example, it is possible to implement the operation pattern of Modification 3 using the atmospheric pressure sensor of Modification 1. FIG. The three operation patterns are applicable not only to the atmospheric pressure sensor, temperature sensor, and acceleration sensor, but also to other sensors. Furthermore, it is also possible to combine position information based on changes in communication delay between RG 12 and GPS or a base station to which RG 12 is connected to the sensor measurement results. Thereby, the accuracy of position information can be improved.

[Modification 2]
In this embodiment, the case of using the IoT platform B has been described. Since various information is aggregated in the IoT platform B, it is possible to determine whether or not the wireless fixed telephone 1 is moving with high accuracy. For example, determination can be made by combining position information based on the change in communication delay. On the other hand, it is also possible not to utilize IoT platform B. In this case, the transmitter 125 of the RG 12 directly transmits the measurement data to the mobile detector 3 of the fixed communication network C. The movement detection device 3 has the determination function that the IoT platform B has by itself.
