Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals indicate similar components.

[First Embodiment]
[overall structure]
FIG. 1 is a block diagram showing a configuration of an information processing system 100 according to the first embodiment. The information processing system 100 includes at least one mobile station device 1, a control server device 2, and a management server device 3.

The mobile station device 1 is mounted on a mobile body 111 such as an automobile, a motorcycle, a ship, or an aircraft. The mobile station device 1 includes, for example, an automobile navigation device and the like.

The control server device 2 is communicably connected to the mobile station device 1 via the wireless communication line W1. The communication between the control server device 2 and the mobile station device 1 is illustrated by the dashed double-headed arrow P1 shown in FIG. The control server device 2 supports the operation of the mobile station device 1, for example, navigation by communicating with the mobile station device 1. Further, the control server device 2 is communicably connected to the management server device 3 via an arbitrary wired or wireless communication line. The communication between the control server device 2 and the management server device 3 is illustrated by the dashed double-headed arrow P2.

The management server device 3 is communicably connected to the mobile station device 1 via the wireless communication line W1. Further, the management server device 3 is communicably connected to the external communication line 6. The management server device 3 manages the external connection to the external communication line 6. The external communication line 6 is, for example, the Internet.

The wireless communication line W1 includes a plurality of base station devices 5. The management server device 3 and the base station device 5 are a part of the telecommunications carrier equipment 112 for providing the service of the wireless communication line W1.

Further, the mobile station device 1 is communicably connected to at least one terminal device 4 via the wireless communication line W2. The terminal device 4 is, for example, a portable personal computer, a tablet computer, or a smartphone.

In response to the signal M21, the management server device 3 transmits a signal M22 including the amount of used data to the control server device 2. Next, the control server device 2 updates the external connection information regarding the mobile station device 1, for example, the contents of the external connection contract, the amount of remaining data, and the external connection state.

Further, in step S112 executed at a predetermined time interval, the control server device 2 checks whether or not a valid external connection contract has been concluded. In this case, in step S22, the control server device 2 checks whether or not the external connection contract has expired based on the external connection information stored in the storage device 23. Next, in step S23, the control server device 2 updates the external connection information regarding the mobile station device 1.

Further, in step S113 executed at predetermined time intervals, the mobile station apparatus 1 acquires external connection information from the control server apparatus 2. First, the mobile station device 1 transmits a signal M23 requesting external connection information to the control server device 2. Next, in step S24, the control server device 2 reads out external connection information regarding the mobile station device 1, for example, the contents of the external connection contract, the amount of remaining data, and the external connection state from the storage device 23. Next, the control server device 2 transmits the signal M24 including the read external connection information to the mobile station device 1. Next, in step S25, the mobile station device 1 stores the external connection information received from the control server device 2 in the storage device 17.

Steps S111 to S113 may be executed in a different order from that shown in FIG. Further, steps S111 to S113 may be executed at different time intervals from each other.

Further, steps S111 to S113 may be executed when communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 is established, and the communication is established. It may be executed if it does not exist.

[Disable wireless LAN and disable external connection]
FIG. 4 is a sequence diagram showing the invalidation of the wireless LAN and the invalidation of the external connection executed by the information processing system 100 of FIG. In the present specification, "invalidation of external connection" means that the management server device 3 prohibits the connection of a certain mobile station device 1 to the external communication line 6. Further, in the present specification, "invalidation of wireless LAN" means turning off the LAN communication device 13.

In step S31, the connection between the terminal device 4 and the external communication line 6 is established via the mobile station device 1 and the management server device 3. As described above, the control server device 2 executes steps S111 and S112 of FIG. 3 at predetermined time intervals, and in step S32, the control server device 2 is based on the result of step S111 or S112 of FIG. Then, the exhaustion of the remaining data amount or the expiration of the external connection contract is detected. In the information processing system 100 according to the first embodiment, when the first control device 21 detects the exhaustion of the remaining data amount or the expiration of the external connection contract, the wireless LAN is invalidated in step S121 and the external connection is made in step S122. Disable.

In step S121, first, the control server device 2 transmits a signal M31 requesting invalidation of the wireless LAN to the mobile station device 1. Next, in step S33, the mobile station device 1 turns off the LAN communication device 13, thereby stopping communication between the mobile station device 1 and the terminal device 4 via the wireless communication line W2. Next, the mobile station device 1 transmits a signal M32 indicating the completion of disabling the wireless LAN to the control server device 2.

In step S122, first, the control server device 2 transmits a signal M34 requesting invalidation of the external connection to the management server device 3. Next, in step S34, the management server device 3 invalidates the external connection so as to stop the use of the external communication line 6 by the mobile station device 1. Next, the management server device 3 transmits a signal M35 indicating the completion of invalidation of the external connection to the control server device 2. Next, in step S35, the control server device 2 updates the external connection information regarding the mobile station device 1, for example, the content of the external connection contract, the amount of remaining data, and the external connection state.

In the present specification, the signal M31 is also referred to as a "first stop signal", and the signal M34 is also referred to as a "second stop signal".

Although FIG. 4 shows a case where step S122 is executed after executing step S121, step S122 may be executed before step S121, and steps S121 and 122 may be executed in parallel.

By disabling both the wireless LAN and the external connection, the communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 is disconnected.

Further, the mobile station device 1 transmits a signal M33 requesting external connection information to the control server device 2. After executing step S35, the control server device 2 transmits the signal M36 including the updated external connection information to the mobile station device 1 in response to the signal M33. Next, in step S36, the mobile station device 1 stores the external connection information received from the control server device 2 in the storage device 17.

According to the operation of FIG. 4, the control server device 2 invalidates both the wireless LAN and the external connection when the external connection information satisfies a predetermined condition. In particular, the control server device 2 has a wireless LAN when the amount of used data exceeds a predetermined threshold value, for example, when the amount of used data reaches the upper limit of the amount of data available by contract. And both external connections may be disabled.

According to the operation of FIG. 4, if the external connection is invalidated, the wireless LAN is also invalidated to stop the generation of unnecessary wireless signals by the mobile station device 1 when the external connection is not available, and the resource. Can be managed efficiently. In particular, the generation of unnecessary wireless signals by the mobile station device 1 can be stopped by a relatively simple operation and configuration in which the control server device 2 transmits a stop signal to the mobile station device 1.

[Summary of the first embodiment]
According to the first embodiment, if the external connection is invalidated, the wireless LAN is also invalidated to stop the generation of unnecessary wireless signals by the mobile station device 1 when the external connection is not available. Resources can be managed efficiently. In particular, the generation of unnecessary wireless signals by the mobile station device 1 can be stopped by a relatively simple operation and configuration in which the control server device 2 transmits a stop signal to the mobile station device 1.

By enabling the external connection during the previous operation of the mobile station device 1, the ignition power of the mobile body 111 is turned on, and the external connection is already enabled when the mobile station device 1 is turned on. There is. However, even in such a case, it is preferable that the mobile station device 1 does not automatically enable the wireless LAN and does not enable the wireless LAN until the user explicitly requests an external connection. .. As will be described later in the second embodiment, the frequency of access from the control server device 2 to the management server device 3 may be limited to a predetermined value, for example, 5 times / second or less. When the wireless LAN is automatically enabled, even if the user does not need communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3, the communication is associated with the communication. Extra access is generated from the control server device 2 to the management server device 3 in order to monitor the amount of used data. Due to such extra access, the amount of used data associated with the communication between the other terminal device 4 and the external communication line 6 via the other mobile station device 1 and the management server device 3 There is concern that the monitoring of the system will be delayed. Therefore, by not enabling the wireless LAN until the user explicitly requests an external connection, it is possible to reduce the delay in monitoring the amount of used data.

Further, in FIG. 3, at least steps S111 and S113 may be executed only when communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 is established. Therefore, the mobile station device 1 may stop the transmission of the signal M23 when the LAN communication device 13 is turned off. The control server device 2 transmits the signal M21 only when the signal M23 is received from the mobile station device 1 at a certain time interval, and does not receive the signal M23 from the mobile station device 1 for a predetermined time length. In that case, the transmission of the signal M21 may be stopped. As will be described later in the second embodiment, the frequency of access from the control server device 2 to the management server device 3 may be limited to a predetermined value, for example, 5 times / second or less. When the control server device 2 transmits the signal M21 regardless of whether communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 is established, the amount of used data is monitored. Even if it is not necessary to do so, extra access from the control server device 2 to the management server device 3 occurs. Due to such extra access, the amount of used data associated with the communication between the other terminal device 4 and the external communication line 6 via the other mobile station device 1 and the management server device 3 There is concern that the monitoring of the system will be delayed. Therefore, by executing steps S111 and S113 only when communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 is established, the amount of used data can be monitored. Delays can be reduced.

[Second Embodiment]
The second embodiment relates to the calculation of the amount of used data related to the communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3.

The information processing system 100 according to the second embodiment has the same configuration as that of the first embodiment.

When communicating between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3, the management server device 3 measures the amount of data of the external connection, and based on the measured amount of data, the amount of data is measured. Communication is controlled by the control server device 2. Communication control includes, for example, charge calculation, communication suspension when the amount of data reaches the upper limit, and the like. In this case, the amount of data measured by the management server device 3 is read from the management server device 3 by the control server device 2.

However, the amount of data read from the management server device 3 may be limited with respect to its format and contents. For example, the following restrictions may be imposed on reading the amount of data.

(1) The management server device 3 can only accept access from other devices such as the control server device 2 up to 5 times per second. With one access, the amount of used data associated with one mobile station device 1 is read out. Also, a single access enables or disables the external connection associated with one mobile station device 1. Therefore, the control server device 2 can only control communications associated with up to 300 mobile station devices 1 in one minute, i.e. up to 18,000 in one hour. (2) Use measured by the management server device 3. The completed data amount has a value calculated from a predetermined day of each month and is reset every month. Therefore, the amount of used data calculated from the start date of the external connection contract or any other time point cannot be read from the management server device 3.
(3) The management server device 3 can hold only the amount of used data for the past two months at the longest. The amount of used data before 3 months is discarded from the management server device 3.

For example, in order to immediately stop communication when the remaining data amount reaches zero, the control server device 2 needs to always accurately grasp the used data amount. However, when the reading of the data amount from the management server device 3 is restricted as described above, it may be difficult for another device to always accurately grasp the used data amount. For example, it is conceivable to modify the management server device 3 so that more accesses can be received at a predetermined time. Further, it is conceivable to modify the management server device 3 so that the used data amount calculated from an arbitrary time point can be read out. Further, it is conceivable to modify the management server device 3 so that the amount of used data can be retained for a longer period of time. However, if the management server device 3 is repaired, it affects the entire telecommunications carrier equipment 112, and therefore, for example, a large amount of cost exceeding several billion yen may be required. Therefore, even when the reading of the measured data amount is restricted, it is required to calculate the data amount with high accuracy by another device.

In the second embodiment, the information processing system 100 capable of calculating the data amount with high accuracy with a relatively simple configuration even when the reading of the measured data amount is restricted will be described. To do.

The control server device 2 requests the management server device 3 to transmit the used data amount at a predetermined first time interval, for example, every 10 minutes. The amount of used data measured by the management server device 3 and transmitted to the control server device 2 is calculated from the beginning of a predetermined time cycle, for example, from a predetermined day of each month. The control server device 2 receives the used data amount from the management server device 3. The control server device 2 is a total of used data calculated from the start of communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 based on the amount of used data. Calculate the amount of remaining data by subtracting the amount from the upper limit of the amount of available data. The latest remaining data amount r (n) is the difference between the latest used data amount u (n) and the previous used data amount u (n-1), and the previous remaining data amount r (n-1). Calculated by subtracting from.

FIG. 5 is a graph showing changes in the amount of used data and the amount of remaining data by the information processing system 100 according to the first embodiment of the second embodiment. FIG. 5 shows a case where a user of the mobile station device 1 and a business operator of the control server device 2 conclude an external connection contract A in which a data amount of up to 1 GB can be used as an upper limit value. In the example of FIGS. 5 to 7, the management server device 3 calculates the amount of used data from the first day of each month. The control server device 2 acquires the used data amount u (n) from the management server device 3 at predetermined time intervals. Therefore, every time the control server device 2 acquires the used data amount u (n), the latest remaining data amount r (n) is calculated by the following equation.

Latest remaining data amount r (n) = previous remaining data amount r (n-1)-(current used data amount u (n) -previous used data amount u (n-1))

For example, when the amount of used data read in order from the management server device 3 is 0MB, 100MB, 200MB, ..., 900MB, 1000MB, the remaining data amount is calculated by the following equation.

1000 = 1000- (0-0)
900 = 1000- (100-0)
800 = 900- (200-100)
...
0 = 100- (1000-900)

In FIGS. 5 to 7, the black circles in the graph schematically show the reading of the used data amount from the management server device 3. In the examples of FIGS. 5 to 7, the used data amount is read out every few days, but the used data amount may be read out at shorter time intervals.

The control server device 2 is externally connected when the remaining data amount becomes equal to or less than a predetermined first threshold value, for example, when the remaining data amount reaches zero or reaches a value close to zero. Disable. As described in the first embodiment, the control server device 2 receives when the remaining data amount becomes equal to or less than a predetermined first threshold value, for example, when the remaining data amount reaches zero, or. When a value close to zero is reached, both the wireless LAN and the external connection may be disabled.

When the remaining data amount becomes greater than the first threshold value and becomes less than or equal to the second threshold value, the control server device 2 determines the amount of used data at a second time interval shorter than the first time interval. You may request the management server device 3 to transmit. The second threshold is set, for example, to 10% of the upper limit of the amount of data available by contract. If the time interval for reading the used data amount from the management server device 3 is relatively long, communication may be continued even after the remaining data amount reaches zero. However, when the remaining data amount approaches zero, the time when the remaining data amount reaches zero can be detected more accurately by shortening the time interval for reading the used data amount from the management server device 3. The second time interval may be a fixed value and may be shortened continuously or discretely as the amount of remaining data approaches zero.

FIG. 6 is a graph showing changes in the amount of used data and the amount of remaining data by the information processing system 100 according to the second embodiment of the second embodiment. FIG. 6 shows that the user of the mobile station device 1 and the operator of the control server device 2 conclude an external connection contract A capable of using a data amount of up to 1 GB as an upper limit value, and then 2 GB as an upper limit value. The case where the external connection contract B which can use the data amount up to is further concluded is shown.

For example, if the amount of used data read in order from the management server device 3 during communication under the external connection contract B is 1000MB, 1100MB, 1200MB, ..., 2900MB, 3000MB, the remaining data amount is calculated by the following equation. ..

1900 = 2000- (1100-1000)
1800 = 1900- (1200-1100)
...
0 = 100- (3000-2900)

FIG. 7 is a graph showing changes in the amount of used data and the amount of remaining data by the information processing system 100 according to the third embodiment of the second embodiment. FIG. 7 shows that the user of the mobile station device 1 and the operator of the control server device 2 conclude an external connection contract A capable of using a data amount of up to 1 GB as an upper limit value, and communicate with the external connection contract B. Indicates a case where is continuously or intermittently continued over a plurality of time cycles, that is, from November to December. As described above, since the management server device 3 calculates the used data amount from the first day of each month, the used data amount is reset on December 1st in FIG. 7. Even in such a case, the latest remaining data amount is calculated as described with reference to FIGS. 5 and 6. However, when the control server device 2 calculates the remaining data amount over the consecutive first and second time cycles, and when the remaining data amount r (n2) is calculated first in the second time cycle, the previous time. Set the amount of used data in to zero. Therefore, the latest remaining data amount r (n2) is calculated by the following equation.

Latest remaining data amount r (n2) = previous remaining data amount r (n1)-(current used data amount u (n) -0

For example, the amount of used data for November read in order from the management server device 3 becomes 0MB, 100MB, 200MB, 300MB, 400MB, and the amount of used data for December read in order from the management server device 3 becomes 0MB, 100MB, 200MB, 300MB, 400MB. When it becomes 100MB, 200MB, 300MB, 400MB, 500MB, the remaining data amount is calculated by the following formula.

1000 = 1000- (0-0)
900 = 1000- (100-0)
800 = 900- (200-100)
700 = 800- (300-200)
600 = 700- (400-300)
500 = 600- (100-0)
400 = 500- (200-100)
300 = 400- (300-200)
200 = 300- (400-300)
100 = 200- (500-400)

In the example of FIG. 7, the amount of used data immediately before being reset on December 1 is not read from the management server device 3, and the control server device 2 cannot know the exact amount of used data at this time. However, when calculating the remaining data amount for the first time in December, by setting the previous used data amount to zero, the total remaining data amount calculated from the start of communication should be calculated with the minimum error. Can be done. Further, in this case, when the control server device 2 calculates the remaining data amount in December, the control server device 2 calculates the remaining data amount without making extra access to the management server device 3 in order to read the past used data amount. can do.

The control server device 2 may invalidate the external connection when the remaining data amount becomes zero. Further, the control server device 2 may invalidate both the wireless LAN and the external connection when the remaining data amount becomes zero.

In the above example, the case where the control server device 2 calculates the remaining data amount has been described, but instead of the remaining data amount, the control server device 2 calculates the total used data amount calculated from the start of communication. You may calculate. Here, the amount of used data measured by the management server device 3 and transmitted to the control server device 2 is also referred to as a "first used data amount". The control server device 2 is calculated and totaled from the start of communication between the terminal device 4 and the external communication line 6 via the mobile station device 1 and the management server device 3 based on the first used data amount. Calculate a second amount of used data that indicates the amount of used data. The second used data amount is calculated by adding the difference between the latest first used data amount and the previous first used data amount to the previous second used data amount. .. The control server device 2 acquires the first used data amount from the management server device 3 at predetermined time intervals. Therefore, every time the control server device 2 acquires the first used data amount, the latest second used data amount is calculated by the following equation.

Latest second used data amount = previous second used data amount + (latest first used data amount-previous first used data amount)

When the second used data amount becomes smaller than the first threshold value, for example, 90% or more of the upper limit value of the data amount available by the contract, the control server device 2 is used. , The management server device 3 may be requested to transmit the first used data amount at a second time interval shorter than the first time interval. If the time interval for reading the first used data amount from the management server device 3 is relatively long, the second used data amount may exceed the upper limit of the data amount available by the contract. However, when the second used data amount approaches the upper limit of the data amount that can be used by the contract, the second used data amount is read from the management server device 3 by shortening the time interval. It is possible to more accurately detect the time when the used data amount reaches the upper limit of the data amount available by the contract. The second time interval may be a fixed value and may be shortened continuously or discretely as the second amount of used data approaches the upper limit of the amount of data available by contract.

The second embodiment is not limited to the case of concluding an external connection contract having an upper limit of the amount of data that can be used according to the paid fee, but is a pay-as-you-go external connection that charges a fee that increases according to the amount of data. It is also applicable when concluding a contract.
