The present invention provides an information processing system capable of suitably suppressing communication traffic in accordance with the usage state of terminals. In the communication traffic suppression system, a monitoring device, on the basis of communication traffic of data flowing through a network, instructs suppression of the communication traffic of transmission data for each terminal device, whereupon the terminal device, on the basis of the terminal device state of the device itself and the received instruction for the suppression, determines the suppression processing method for the communication traffic of the transmission data, applies the communication traffic suppression processing for the data to be transmitted to the outside using the determined suppression processing method, and performs the transmission.

Description

Information processing system for suppressing traffic and method for suppressing traffic

The present invention relates to an information processing system, a communication amount suppressing method, and a communication amount suppressing program, and more particularly to an information processing system, a communication amount suppressing method, and a communication amount suppressing program for suppressing the communication amount of a communication device connected to a network.

In recent years, sensor network systems that measure temperature, vibration, and the like using a terminal equipped with a sensor and transmit measurement data as a measurement result to a server via a network have been spreading. In such a sensor network system, the amount of data transmitted / received becomes very large depending on the number of terminals and the frequency of data transmission / reception. For this reason, there are problems such as network congestion. This problem is common to information processing systems in which a large number of terminals connected via a network regularly transmit and receive data to and from the server, including the sensor network system described above. . In order to solve such a problem, it is necessary to suppress the communication amount between the server and the terminal.

Patent Document 1 discloses a technique for suppressing the amount of communication between a server and a terminal. The printer control system described in Patent Literature 1 includes a terminal (client computer: printing apparatus) and a server (host computer) connected via a communication network interface (also simply referred to as “network”).

The terminal measures the network traffic (traffic volume). Next, when the terminal determines that the communication amount is excessive, the terminal repeats the measurement until the communication amount of the network becomes smaller than a predetermined amount. Then, the terminal resumes communication with the server when the communication amount becomes smaller than a predetermined amount. By the above-described operation, an increase in the traffic of the network is suppressed.

Patent Document 2 discloses a technique for reducing the amount of information transmitted from a sensor terminal. The remote monitoring system described in Patent Literature 2 includes a sensor terminal and a central server that are communicably connected.

Each of the sensor terminals measures a signal related to the monitoring target, compresses it, and transmits it to the central server. Each of the sensor terminals transmits the content of the compression processing of the signal and the relationship between the compression error and the compression rate to the central server.

The central server receives the compressed signal and restores the compressed signal. Further, the central server receives the content of the compression process, the relationship between the compression error and the compression rate, calculates the compression rate of the entire sensor terminal, calculates the compression rate that is within the allowable error range, It transmits to each of the sensor terminals. With the above-described configuration, the communication amount of the network connecting the sensor terminal and the central server is reduced.

JP 2001-282468 A JP 2009-110419 A

However, the technique described in the above-described prior art document has a problem that the communication amount cannot be appropriately suppressed so as to correspond to the usage status of the terminal.

The reason is as follows.

This is because the terminal of the printer control system described in Patent Document 1 determines the resumption of communication with the server based only on the traffic of the network.

Further, the central server of the remote monitoring system described in Patent Document 2 calculates the compression rate instructed to each of the sensor terminals based only on the content of the compression process and the relationship between the compression error and the compression rate. It is.

That is, neither the technology of Patent Document 1 nor the technology of Patent Document 2 considers the usage status of a terminal that changes every moment when the amount of communication is suppressed.

Specifically, when a user uses an application such as e-mail on a terminal, if the suppression process is performed on that terminal, the processing speed of the entire terminal is reduced, which affects the operation performance of the application. Is expected. Therefore, even when the network traffic exceeds a certain flow rate, it is desirable that the user does not suppress the traffic of the terminal when the user is using the application on the terminal. However, since the technique described in the above-mentioned patent document does not consider the usage status of the terminal, it cannot be determined that the technique does not intentionally suppress the communication amount of the terminal.

Also, there is an environment in which terminals with a relatively small decrease in convenience when the communication amount is suppressed and terminals with a relatively large decrease in convenience when the communication amount is suppressed are mixed. In such an environment, it can be said that it is desirable to reduce the decrease in convenience of the latter terminal by relatively increasing the amount of suppression of the former terminal. However, the technique described in the above-mentioned patent document does not consider the usage status of the terminal. Therefore, those techniques cannot determine the degree of suppression of communication amount according to the state of each terminal.

An object of the present invention is to provide an information processing system, a communication amount suppression method, and a communication amount suppression program that can solve the above-described problems.

<<<< first embodiment >>>>
The basic configuration of the first embodiment of the present invention will be described.

=== Communication Volume Suppression System 100 ===
FIG. 1 is a block diagram showing a configuration of a traffic control system (also called an information processing system) 100 according to the first embodiment of the present invention.

Referring to FIG. 1, the traffic volume suppression system 100 according to the present embodiment includes a terminal device 10, a traffic volume monitoring unit 201, and a suppression instruction unit 204. The terminal device 10 includes a data generation unit 101, a communication amount suppression unit 102, a suppression processing method determination unit 103, and a terminal state acquisition unit 104. The terminal device 10 may be an arbitrary number of one or more.

The data generation unit 101, the communication amount suppression unit 102, the suppression processing method determination unit 103, the terminal state acquisition unit 104, the communication amount monitoring unit 201, and the suppression instruction unit 204 illustrated in FIG. Alternatively, it may be a component divided into functional units of the computer device.

=== Communication amount monitoring unit 201 ===
The traffic monitoring unit 201 measures the amount of data flowing through a network (not shown) to which the terminal device 10 is connected (first traffic, hereinafter referred to as traffic w). Here, the value of the communication amount w is, for example, Mbps (Megabit per second) calculated by summing the number of transfer bytes every 50 milliseconds for the past 20 times (that is, for 1 second), and 1 byte is 8 bits. It is a value indicated in megabits per second).

=== Suppression Instruction Unit 204 ===
Based on the communication amount w measured by the communication amount monitoring unit 201, the suppression instruction unit 204 sends the terminal device 10 the amount of transmission data (second communication amount, hereinafter, A suppression instruction for instructing suppression of communication amount (tw) is transmitted. Here, the value of the traffic volume tw is a value indicated in Mbps similar to the value of the traffic volume w. The suppression instruction includes a suppression parameter (also referred to as instruction content) indicating how to suppress the communication amount tw (for example, a suppression processing method for suppressing data or an upper limit value of the communication amount tw).

=== Terminal Status Acquisition Unit 104 ===
The terminal state acquisition unit 104 acquires information indicating the state of the terminal device 10 (also referred to as terminal state information).

=== Suppression Processing Method Determination Unit 103 ===
The suppression processing method determination unit 103 receives the suppression instruction transmitted from the suppression instruction unit 204. Next, the suppression processing method determination unit 103 determines a suppression processing method for the communication amount tw based on the suppression parameter included in the received suppression instruction and the terminal state information acquired by the terminal state acquisition unit 104.

Here, when the suppression processing method determination unit 103 determines to execute the traffic amount suppression process corresponding to the suppression parameter, the suppression processing method determination unit 103 determines the suppression processing method corresponding to the suppression parameter. Here, the suppression processing method corresponding to the suppression parameter is, for example, the suppression processing method when the suppression parameter indicates the suppression processing method. In addition, the suppression processing method corresponding to the suppression parameter is a suppression processing method in which, when the suppression parameter indicates the upper limit value of the communication amount tw, the communication amount tw is equal to or lower than the upper limit value.

In addition, when the suppression processing method determination unit 103 determines to execute a suboptimal traffic suppression process with a degree of suppression lower than that of the traffic suppression process corresponding to the suppression parameter, the suppression processing method determination unit 103 With reference to the suppression parameter, a suppression processing method corresponding to the next-best communication amount suppression processing is determined. The suppression processing method corresponding to the next-best communication amount suppression processing is, for example, a suppression processing method having a lower degree of suppression than the suppression processing method when the suppression parameter indicates the suppression processing method. In addition, the suppression processing method corresponding to the suboptimal traffic volume suppression process is such that, for example, when the suppression parameter indicates the upper limit value of the traffic volume tw, the traffic volume tw is the closest value to the upper limit value. This is a proper suppression method.

Further, when it is determined that the communication amount tw is not suppressed (the communication amount suppression process is not executed), the suppression processing method determination unit 103 determines that the suppression processing method is “none”.

=== Communication Traffic Suppression Unit 102 ===
The traffic volume suppression unit 102 performs a traffic volume suppression process on the data dk using the suppression processing method determined by the suppression processing method determination unit 103. Next, the traffic volume suppression unit 102 transmits the data subjected to the traffic volume suppression process to the outside. In other words, the communication amount suppression unit 102 suppresses the communication amount tw by performing a communication amount suppression process on the data dk. Hereinafter, the data transmitted or transmitted by the communication amount suppression unit 102 is referred to as data ds. Note that the data that the communication amount suppression unit 102 transmits to the outside or transmits the data dk without performing the communication amount suppression process is also referred to as data ds.

The data is transmitted to the server device 30 via the network 40.

=== Terminal Status Acquisition Unit 104 ===
The terminal state acquisition unit 104 acquires terminal state information of the terminal devices 11 to 1n on which the terminal state acquisition unit 104 is mounted. The terminal status information is information indicating the remaining battery level of the terminal devices 11 to 1n, for example.

=== Suppression Processing Method Determination Unit 103 ===
The suppression processing method determination unit 103 determines a suppression processing method to be executed in response to the suppression instruction received from the monitoring device 20 based on the terminal state information acquired by the terminal state acquisition unit 104. Next, the suppression processing method determination unit 103 stores the determined suppression processing method in the suppression processing method storage unit 105.

=== Suppression Processing Method Storage Unit 105 ===

=== Connected Terminal Storage Unit 202 ===
The connection terminal storage unit 202 stores a connection terminal list of the terminal devices 11 to 1n connected to the communication network 40.

FIG. 3 is a diagram illustrating an example of a connection terminal list stored in the connection terminal storage unit 202. For example, it is assumed that the terminal devices 11 to 1n are mobile phones and the communication network 40 is a wireless network covered by one mobile phone base station. In this case, as shown in FIG. 3, the connection terminal storage unit 202 stores a list of identifiers of the mobile phones using the mobile phone base station as the connection terminal list.

=== Suppression Effect Storage Unit 203 ===
The suppression effect storage unit 203 stores a suppression effect list 700 indicating how much the communication amount w is reduced when a certain suppression processing method is adopted for the terminal devices 11 to 1n.

FIG. 4 is a diagram illustrating an example of the suppression effect list 700 stored in the suppression effect storage unit 203. As illustrated in FIG. 4, for example, the suppression effect list 700 includes “0”, “1”, “2”, and “3” of process IDs (Identifiers) with “ The definitions of “none”, “compression”, “difference + compression”, “intermittent transmission + compression” are stored. Note that “None” in the processing content indicates that no suppression is performed. “Compression” indicates a method of simply compressing data. “Difference + compression” indicates a method of compressing after calculating difference information from previously transmitted data. Further, “intermittent transmission + compression” indicates a method of reducing the data transmission interval from the terminal apparatuses 11 to 1n and further combining with data compression. Furthermore, the suppression effect list 700 stores, as an average suppression effect (for example, a suppression rate expressed as a percentage (%)), the amount of data that can be suppressed on average for each processing content.

When the suppression processing method that can be executed corresponding to each of the terminal devices 11 to 1n and the suppression effect thereof are different, the suppression effect storage unit 203 stores the suppression effect list 700 for each of the terminal devices 11 to 1n. It may be. In this case, each of the terminal devices 11 to 1n further holds the suppression effect list 700. When each of the terminal devices 11 to 1n is connected to the communication network 40, the suppression effect list 700 is stored in the suppression effect storage unit.

Next, the suppression instruction unit 204 transmits a suppression instruction including the determined suppression parameter to the terminal devices 11 to 1n. This suppression parameter is, for example, the process ID shown in the suppression effect list 700 of FIG. A detailed operation related to the communication amount suppression process will be described later.

=== Instruction State Storage Unit 205 ===
The instruction state storage unit 205 stores a suppression instruction list indicating the suppression instruction content transmitted by the suppression instruction unit 204 to the terminal devices 11 to 1n.

FIG. 5 is a diagram illustrating an example of the suppression instruction list 701 stored in the instruction state storage unit 205. As shown in FIG. 5, the suppression instruction list 701 stores information indicating that “1” is instructed as a suppression parameter to any of the terminal devices 11 to 1n whose terminal ID is “1002”, for example. Here, the suppression parameter “1” indicates a suppression processing method in which the process ID of the suppression effect list 700 illustrated in FIG. 4 is “1”.

The suppression instruction unit 204 may use the suppression instruction list 701 when determining the suppression parameters for the terminal devices 11 to 1n. For example, when the communication amount w of the communication network 40 does not decrease, a more effective suppression instruction may be transmitted to each of the terminal devices 11 to 1n. Here, a more effective suppression instruction is a suppression instruction that includes a suppression parameter that instructs a more effective traffic volume suppression process than the traffic volume suppression process corresponding to the suppression parameter stored in the suppression instruction list 701. .

Server device 30 includes a suppression state determination unit 301 and a data processing unit 302.

=== Suppression State Determination Unit 301 ===
The suppression state determination unit 301 determines whether or not the data ds received from the terminal devices 11 to 1n has been subjected to a traffic amount suppression process. When the data ds has been subjected to the traffic amount suppression process, the suppression state determination unit 301 restores the data ds to the data before the traffic amount suppression process, and transmits the data ds to the data processing unit 302. In addition, when the data ds is not subjected to the communication amount suppression process, the suppression state determination unit 301 transmits the data ds as it is to the data processing unit 302.

=== Data Processing Unit 302 ===
The data processing unit 302 is a server-side application that uses data ds received from the terminal devices 11 to 1n, for example. Specifically, the data processing unit 302 is an application that analyzes past behaviors of mobile phone users and predicts future behaviors based on mobile phone movement records and vibration information. . Alternatively, the data processing unit 302 may be an application that collects air temperatures in various regions and analyzes temperature changes.

Next, the operation related to the control of traffic will be described in detail.

In normal times, the terminal devices 11 to 1n transmit the data dk as data ds as they are to the server device 30 via the communication network 40. The suppression state determination unit 301 of the server device 30 sends the received data ds as it is to the data processing unit 302, and the data processing unit 302 performs processing such as accumulation and analysis of the received data ds.

=== Operation on the Monitoring Device 20 Side Related to Suppression of Communication Volume ===
On the other hand, when the communication amount monitoring unit 201 of the monitoring device 20 detects that the communication amount w of the communication network 40 exceeds a certain flow rate (limit value), the suppression instruction unit 204 instructs the terminal devices 11 to 1n to Determine the parameters. The suppression instruction unit 204 includes a suppression effect list 700 stored in the suppression effect storage unit 203 and a suppression instruction list 701 stored in the instruction state storage unit 205 based on the communication amount w measured by the communication amount monitoring unit 201. Is used to determine the suppression parameter.

Next, the suppression instruction unit 204 transmits a suppression instruction including the determined suppression parameter to the suppression processing method determination unit 103 of the terminal devices 11 to 1n. Further, the suppression instruction unit 204 records the transmitted suppression parameter in the instruction state storage unit 205.

At this time, the suppression instruction unit 204 determines the suppression parameter as follows. For example, the suppression instruction unit 204 uses the measured current communication amount w, the limit value, and the average suppression effect of the suppression effect list 700 to select any one of the plurality of suppression processes f satisfying Expression 1. Select. Next, the suppression instruction unit 204 transmits a suppression instruction to each of the terminal devices 11 to 1n using the process ID that identifies the selected suppression process f as a suppression parameter.

Here, w is the value of the current communication amount w, r (f) is the average suppression effect ratio of the processing f (the value indicating the average suppression effect indicating the amount of data to be suppressed expressed as a percentage with respect to 1), L is a limit value for the communication amount w.

Thereafter, the communication amount monitoring unit 201 continues to measure the communication amount w, and the suppression instruction unit 204 determines a suppression parameter of a suppression instruction to be transmitted next as the communication amount w changes. For example, the suppression instruction unit 204 operates as follows.

FIG. 6 is a diagram illustrating an example of a suppression instruction determination table 702 held in a storage unit (not illustrated) of the suppression instruction unit 204. As illustrated in FIG. 6, the suppression instruction determination table 702 includes the suppression parameter (processing ID) of the suppression instruction transmitted by the suppression instruction unit 204 last time, and the conditions A, B, and C corresponding to the change in the traffic w. The correspondence with the suppression parameter (process ID) of the suppression instruction | command transmitted next by the suppression instruction | indication part 204 in each is shown. Here, the conditions A, B, and C are, for example, as follows.

Condition A: (current traffic w) − (limit value L) <− (threshold).

Condition B: | (current traffic w)-(limit value L) | ≤ (threshold).

Condition C: (current traffic w)-(limit value L)> (threshold value).

Thereafter, the communication amount monitoring unit 201 continuously measures the communication amount w, and the suppression instruction unit 204 determines a suppression parameter to be instructed next to the terminal devices 11 to 1n.

<Modification Example 1 of Operation of Suppression Instruction Unit 204>
The suppression instruction unit 204 may first instruct each of the terminal devices 11 to 1n of a suppression parameter indicating a method having the lowest suppression effect (not impairing convenience). And the suppression instruction | indication part 204 may instruct | indicate the suppression parameter with a high suppression effect one step at a time. For example, in the case of the suppression effect list 700 illustrated in FIG. 4, the suppression parameter indicating the method having the lowest suppression effect is a process ID that identifies “compression”, which is a suppression processing method having an average suppression effect (%) of “30”. “1”.

<Modification Example 2 of Operation of Suppression Instruction Unit 204>
In addition, the suppression instruction unit 204 may instruct each of the terminal devices 11 to 1n to execute the traffic amount suppression process with the highest suppression effect. In other words, the suppression instruction unit 204 may transmit, to each of the terminal devices 11 to 1n, a suppression instruction including a suppression parameter that specifies a traffic amount suppression process with the highest degree of suppression. In such a case, it can be expected that the terminal devices 11 to 1n having little influence on the operation of the application and the convenience of the user even if the communication amount tw is suppressed greatly suppress the communication amount tw.

<Modification Example 3 of Operation of Suppression Instruction Unit 204>
Further, the suppression instruction unit 204 may transmit a suppression instruction including different suppression parameters to each of the terminal devices 11 to 1n.

For example, when the current communication amount w is 120 Mbps, the limit value L is 100 Mbps, and the average suppression effect of the process ID = 1 is 30% (that is, r (f) = 0.3), the suppression instruction unit 204 is Then, the suppression processing method specified by the processing ID = 1 is selected using Equation 1. Next, when the suppression instruction unit 204 transmits a suppression instruction including a suppression parameter of process ID = 1 to each of all the terminal devices 11 to 1n, the subsequent communication amount w becomes about 84 Mbps. In this case, it can be considered that the communication amount w is excessively suppressed in the 84 Mbps with respect to the limit value L which is 100 Mbps. Therefore, the suppression instruction unit 204 may transmit a suppression instruction only to a part of the terminal devices 11 to 1n. The suppression instruction unit 204 determines the ratio of the number of terminal devices 11 to 1n that transmit the suppression instruction using, for example, Equation 2 shown below.

Here, a is a ratio of the number of terminal devices 11 to 1n to which the suppression instruction unit 204 transmits a suppression instruction, and r (f) is a process f (in this case, a suppression processing method identified by the process ID “1”). Is the average suppression effect ratio. The suppression instruction unit 204 calculates a ≧ 0.77 using Equation 2 based on the above-described conditions. Therefore, the suppression instruction unit 204 transmits a suppression instruction only to 77% of the terminal devices 11 to 1n out of all the terminal devices 11 to 1n, and does not transmit a suppression instruction to the remaining 23% of the terminal devices 11 to 1n. To do. In such a case, the value of the communication amount w is expected to be about 100 Mbps.

At this time, the suppression instruction unit 204 may randomly select about 77% of the terminal devices 11 to 1n. Further, the suppression instruction unit 204 may refer to the instruction state storage unit 205 and preferentially select the terminal devices 11 to 1n that have a small suppression of the communication amount tw by the suppression instruction transmitted in the past. Alternatively, the suppression instruction unit 204 stores, in a storage unit (not shown), the number of suppression instructions transmitted in the past for each of the terminal devices 11 to 1n, and preferentially selects the terminal devices 11 to 1n with the smaller number of times. May be.

<Modification Example 4 of Operation of Suppression Instruction Unit 204>
Further, the suppression instruction unit 204 may determine a suppression instruction for each of the terminal devices 11 to 1n so as to satisfy Equation 3 more generally, and transmit it to the terminal devices 11 to 1n.

Here, n is the number of terminal devices 11 to 1n, f (i) is a suppression instruction transmitted to the i-th terminal devices 11 to 1n, and r (f (i)) is an average suppression effect ratio thereof. When the communication amount suppression process is not performed, the average suppression effect ratio is calculated as “0”.

The above is the description of the operation on the monitoring device 20 side related to the suppression of the traffic.

=== Operations on the side of the terminal devices 11 to 1n related to the control of the traffic volume ===
The suppression processing method determination unit 103 determines whether to execute the suppression instruction received from the suppression instruction unit 204 based on the states of the terminal devices 11 to 1n acquired by the terminal state acquisition unit 104.

For example, in the following case, the suppression processing method determination unit 103 determines not to execute the suppression instruction.

The first case is a case where the remaining battery levels of the terminal devices 11 to 1n are low. In this case, when the communication amount suppression process is performed, it is expected that the battery consumption increases and the usable time of the terminal apparatuses 11 to 1n is shortened.

The second case is a case where a user uses an application such as e-mail on the terminal devices 11 to 1n which are mobile phones. In this case, if the communication amount suppression process is performed, it is expected that the processing speed of the terminal devices 11 to 1n as a whole decreases and affects the convenience of the application.

The third case is a case where the users of the terminal devices 11 to 1n are moving at high speed. In this case, when the communication amount suppression process is performed, it is expected that the recording accuracy of the position information is lowered and the application operating on the server device 30 is affected.

The fourth case is a case immediately after the building security device detects some abnormality. In this case, if the communication amount suppression process is performed, it is expected that the recording frequency and resolution of the camera image will be reduced, causing trouble in crime prevention.

In addition to the above case, the suppression processing method determination unit 103 may determine that the suppression instruction is not executed.

Alternatively, instead of determining that the communication amount suppression process based on the suppression instruction is not performed, the suppression processing method determination unit 103 has a lower degree of suppression than the suppression processing method corresponding to the suppression parameter included in the suppression instruction. You may make it determine the suboptimal suppression processing method. This sub-optimal suppression processing method is a suppression processing method that has less influence on the operation of the application, the convenience of the user, and the like than the suppression processing method corresponding to the suppression parameter included in the suppression instruction.

FIG. 7 is a diagram illustrating an example of a suppression processing method change table 703 held in a storage unit (not shown) of the suppression processing method determination unit 103. As illustrated in FIG. 7, the suppression processing method change table 703 indicates a suppression processing method (processing ID) corresponding to a combination of a suppression parameter (processing ID) and terminal state information.

For example, the suppression processing method determination unit 103 changes the suppression processing method using the suppression processing method change table 703 shown in FIG. For example, the suppression processing method determination unit 103 uses the suppression processing method change table 703 when the terminal 11 to 1n has a remaining battery level of 10% or less when receiving a suppression instruction of process ID = 1. The suppression processing method is changed to the suppression processing method specified by process ID = 0 (that is, the traffic amount suppression process is not performed).

As described above, the suppression processing method determination unit 103 determines the suppression processing method so that the convenience of the terminal devices 11 to 1n is not impaired as much as possible when the communication amount tw suppression processing is executed. In other words, as long as the convenience of the terminal devices 11 to 1n is not impaired, the suppression processing method determination unit 103 has an effect that is as close as possible to the traffic amount suppression process corresponding to the suppression parameter included in the suppression instruction or the traffic amount suppression process. To determine the suppression processing method.

The suppression processing method determination unit 103 stores the determined suppression processing method in the suppression processing method storage unit 105.

The communication amount suppression unit 102 transmits the data dk to the server device 30 by compressing the data dk or transmitting only the difference information of the data dk according to the suppression processing method stored in the suppression processing method storage unit 105. The amount tw is suppressed.

In addition, when the suppression processing method determination unit 103 determines that the communication amount suppression processing is not performed and the fact (for example, “none”) is stored in the suppression processing method storage unit 105, the communication amount suppression unit 102 performs communication. The communication amount suppression process for the amount tw is not executed.

<Modification Example 1 of Operations on Terminal Devices 11 to 1n>
Further, the terminal status acquisition unit 104 directly inquires of the users of the terminal devices 11 to 1n whether or not the communication amount suppression process can be executed. May be determined.

FIG. 8 is an example of an inquiry screen when the terminal state acquisition unit 104 inquires of the user whether or not the communication amount suppression process can be executed.

The suppression processing method determination unit 103 determines a suppression processing method that executes a traffic amount suppression process when the terminal state acquisition unit 104 acquires that the user has selected Yes. Further, when the terminal state acquisition unit 104 acquires that the user has selected No, the suppression processing method determination unit 103 determines “none” as the suppression processing method.

<Modification Example 2 of Operations on Terminal Devices 11 to 1n>
In addition, the user of the terminal devices 11 to 1n may be able to specify the reference when the suppression processing method determination unit 103 changes the communication amount suppression processing method.

FIG. 9 is an example of a reference setting screen that allows the user to set a reference when changing the suppression processing method. The reference setting screen shown in FIG. 9 indicates that the user has set the reference so that the communication amount suppression process is not executed when the remaining battery level is 10% or less.

The suppression processing method determination unit 103 acquires a criterion set by the user, and reflects the acquired criterion in the suppression processing method change table 703, for example.

=== Operations on the Server Device 30 Side Related to Suppression of Communication Volume ===
The suppression state determination unit 301 of the server device 30 decompresses the received data ds or calculates the original data (data dk) from the difference information, and the data (data dk) before the communication amount suppression process is performed. , And the restored data is sent to the data processing unit 302.

At this time, the suppression state determination unit 301 needs to correctly determine how the data ds received from the terminal devices 11 to 1n is processed and transmitted on the terminal devices 11 to 1n side. For this reason, typically, the traffic volume suppression unit 102 transmits data ds to which the process ID indicating the content of the traffic volume suppression process is added to the server device 30. And the suppression state determination part 301 performs a decompression | restoration process based on the process ID added to the received data ds. Note that the communication amount suppression unit 102 may add the processing ID to all data ds to be transmitted, or add the processing ID only to the data ds that is transmitted first after the suppression processing method is changed. You may make it do.

The above is the description of the operation related to the control of the traffic.

Next, the overall operation of this embodiment will be described in detail with reference to the drawings.

FIG. 10 is a flowchart showing an operation of transmitting data ds from the terminal devices 11 to 1n to the server device 30 among the operations of the communication volume control system 100.

The data generation unit 101 of the terminal devices 11 to 1n generates data dk (step S101).

Next, the communication amount suppression unit 102 checks the suppression processing method stored in the suppression processing method storage unit 105, and determines whether or not the suppression process needs to be executed (step S102). If the suppression processing method is “none” (NO in step S102), the process proceeds to step S105.

When the suppression processing method is other than “None” (YES in Step S102), the traffic volume suppression unit 102 executes the traffic volume suppression process based on the suppression processing method stored in the suppression processing method storage unit 105 (Step S102). S103).

Next, the traffic amount suppression unit 102 checks whether there is data ds to be transmitted (step S104). The case where there is no data ds to be transmitted is a case where there is no data to be transmitted as a result of the communication amount suppression process. If there is no data ds to be transmitted (NO in step S104), the process returns to step S101. If there is data ds to be transmitted (YES in step S104), the process proceeds to step S105.

In step S105, the traffic amount suppressing unit 102 transmits the data ds to the server device 30 via the communication network 40 (step S105). Then, the processing of the terminal devices 11 to 1n returns to step S101. Note that the processing of the monitoring device 20 may end after step S105. In this case, the monitoring device 20 may start the process from step S101 when a factor for generating the data dk occurs, or start the process from step S101 at regular intervals. It may be.

Next, the suppression state determination unit 301 of the server device 30 receives the data ds from the terminal devices 11 to 1n (step S106).

Next, the suppression state determination unit 301 determines whether or not the received data ds is the data ds that has been subjected to the communication amount suppression process (step S107). If the data is not the data ds subjected to the communication amount suppression process (NO in step S107), the process proceeds to step S109.
If the data ds has been subjected to the traffic amount suppression process (YES in step S107), the suppression state determination unit 301 restores the data ds to the data before the traffic amount suppression process (step S108).

Next, in step S109, the data processing unit 302 performs processing using the restored data (step S109). And the process of the server apparatus 30 is complete | finished.

FIG. 11 is a flowchart showing an operation of generating a suppression instruction in the monitoring device 20 and an operation of determining a suppression processing method in the terminal devices 11 to 1n among the operations of the communication amount suppression system 100.

The communication amount monitoring unit 201 of the monitoring device 20 measures the communication amount w of the communication network 40 (step S201 in FIG. 11).

Next, the suppression instruction unit 204 generates a suppression parameter for each of the terminal devices 11 to 1n based on the measurement result of the traffic monitoring unit 201 and records it in the suppression instruction list 701 (step S202).

Next, the suppression instruction unit 204 transmits a suppression instruction including the generated suppression parameter to each of the terminal devices 11 to 1n (step S203). And the process of the monitoring apparatus 20 returns to step S201. Note that the processing of the monitoring device 20 may end after step S203. In this case, the monitoring device 20 may start the processing from step S201 at regular time intervals.

The suppression processing method determination unit 103 of the terminal devices 11 to 1n receives a suppression instruction from the monitoring device 20 (step S204).

Next, the terminal state acquisition unit 104 acquires the states of the terminal devices 11 to 1n (step S205).

Next, the suppression processing method determination unit 103 determines a suppression processing method for the traffic tw based on the received suppression instruction and the terminal state acquired by the terminal state acquisition unit 104 (step S207).

Next, the suppression processing method determination unit 103 stores the determined suppression processing method for the traffic tw in the suppression processing method storage unit 105 (step S208). Then, the processing of the terminal devices 11 to 1n ends.

The above is the description of the overall operation of this embodiment.

Note that the communication amount w measured by the communication amount monitoring unit 201 is, for example, the total amount of all data flowing through the communication network 40. That is, in the case where data transmitted from other terminals or servers other than data transmitted from the terminal devices 11 to 1n is flowing through the communication network 40, the communication amount w is the total amount of all the data. is there. Even in such a case, the communication amount can be appropriately suppressed by repeating the measurement of the communication amount w and the suppression instruction changed based on the measurement result.

<Modification 1 of this embodiment>
There may be a plurality of communication networks 40. In that case, the number of monitoring devices 20 may be the same as the number of communication networks 40 so that the communication amount w can be monitored for each communication network 40 and the content of the communication amount suppression process can be determined. Thereby, even when the number of terminal devices 11 to 1n connected to each communication network 40 and the limit value of the communication amount w are different for each communication network 40, the communication amount w is appropriately set in each communication network 40. Can be suppressed.

<Modification 2 of this embodiment>
The suppression instruction unit 204 may transmit a suppression instruction including a suppression parameter that differs for each type of data dk to the suppression processing method determination unit 103. In this case, the suppression effect list 700 stored in the suppression effect storage unit 203 and the suppression instruction list 701 stored in the instruction state storage unit 205 may be provided for each type of data dk. In addition, the suppression instruction unit 204, the suppression processing method determination unit 103, the communication amount suppression unit 102, and the suppression state determination unit 301 may perform processing by determining the type of data dk or data ds. Further, the suppression processing method storage unit 105 may perform storage for each type of data dk.

<Modification 3 of this embodiment>
The monitoring device 20 and the server device 30 may be realized by one computer, for example.

<Modification 4 of this embodiment>
The suppression instruction unit 204 may include, as a suppression parameter, the upper limit value of the communication amount tw (the number of bytes per second or the ratio to the normal time) in the suppression instruction instead of the process ID. In this case, instead of providing the suppression effect storage unit 203 in the monitoring device 20, a suppression effect storage unit (not shown) may be provided in each of the terminal devices 11 to 1n. Then, the suppression processing method determination unit 103 of each of the terminal devices 11 to 1n refers to the suppression effect list 700 stored in the suppression effect storage unit of each of the terminal devices 11 to 1n, and the traffic corresponding to the suppression parameter It may be determined whether or not the traffic amount suppression process of tw is possible.

<Modification 5 of this embodiment>
The suppression processing method determination unit 103 may determine (change) the suppression processing method at an arbitrary timing.

For example, in the flowchart shown in FIG. 11, the suppression processing method determination unit 103 of the terminal devices 11 to 1n determines the suppression processing method (step S205, step S207, and step S208). The reception of the suppression instruction (step S204) It is immediately after. However, the suppression processing method determination unit 103 may acquire the states of the terminal devices 11 to 1n at an arbitrary timing and determine (change) the suppression processing method regardless of whether or not a suppression instruction is received.

In this way, the suppression processing method determination unit 103 can immediately perform the traffic amount suppression processing method according to the state change of the terminal devices 11 to 1n, for example, when the user starts operating the terminal devices 11 to 1n. Can be changed. In the modification of this embodiment, the state of the terminal devices 11 to 1n is transmitted to the monitoring device or the server device, and the monitoring device or the server device determines a suppression processing method for the communication amount suppression processing, Has one of the unique effects.

The first effect of the present embodiment described above is that the amount of communication can be appropriately suppressed so as to correspond to the usage status of the terminal.

The reason is that the following configuration is included. That is, first, the suppression instruction unit 204 generates a suppression parameter based on the communication amount w monitored (measured) by the communication amount monitoring unit 201. Second, the suppression processing method determination unit 103 determines the suppression processing method based on the suppression parameter and the terminal state information acquired by the terminal state acquisition unit 104. Thirdly, based on the suppression processing method, the traffic volume suppression unit 102 executes transmission of the data ds obtained by performing the suppression process on the data dk generated by the data generation unit 101.

The second effect of the present embodiment described above is that the amount of traffic tw can be suppressed fairly between the terminal devices 11 to 1n from the viewpoint of convenience.

The reason is that, as long as the convenience of the terminal devices 11 to 1n is not impaired, the suppression processing method determination unit 103 is as close as possible to the traffic volume suppression process corresponding to the suppression parameter included in the suppression instruction or the traffic volume suppression process. This is because the suppression processing method that can obtain the effect is determined. In other words, the suppression processing method determination unit 103 determines a more effective suppression processing method as the influence of the suppression of the communication amount tw is smaller from the viewpoint of convenience.

The third effect of the present embodiment described above is that the network traffic w can be appropriately suppressed according to the current usage status of the terminal devices 11 to 1n.

The reason is that after the suppression instruction unit 204 instructs the traffic amount suppression process, the suppression processing method determination unit 103 changes the suppression processing method at an arbitrary timing based on the current state of the terminal devices 11 to 1n. It was because it did so.

The fourth effect of the present embodiment described above is that the communication amount tw can be more fairly suppressed between the terminal devices 11 to 1n in terms of convenience.

The reason is that the suppression instruction unit 204 first sends a suppression parameter indicating a method that is gradually more effective from a suppression parameter that indicates a method having the lowest suppression effect (not impairing convenience) to each of the terminal devices 11 to 1n. This is because it was instructed. That is, the suppression instruction unit 204 instructs the terminal devices 11 to 1n to perform a traffic amount suppression process that is gradually more effective until the network flow rate becomes equal to or less than the limit value. On the other hand, each of the terminal devices 11 to 1n executes the maximum amount of traffic suppression process that can be executed within the range of the specified suppression parameter.

The fifth effect of the present embodiment described above is that the amount of communication tw can be suppressed according to the usage status of the latest terminal devices 11 to 1n while suppressing the load on the communication network 40.

The reason is that each of the terminal devices 11 to 1n that has received the suppression instruction acquires the current latest state of the terminal state acquisition unit 104, and the suppression processing method determination unit 103 actually executes the traffic amount suppression process. This is because it is determined whether or not to do so. That is, the communication amount suppression system 100 according to the present embodiment includes a configuration in which the terminal devices 11 to 1n do not need to transmit the latest terminal state information to the monitoring device 20.

The sixth effect of the present embodiment described above is that an optimal communication amount suppression process can be executed as the entire information processing system.

The reason is that the following configuration is included. First, the suppression instruction unit 204 grasps the network traffic w and the traffic volume suppression processing status of all the terminal devices 11 to 1n. Second, the suppression instruction unit 204 determines a combination of suppression parameters to be instructed to each of the terminal devices 11 to 1n so that the network traffic w is less than or equal to the limit value L.

The seventh effect of the present embodiment described above is that the terminal devices 11 to 1n that have little influence on the operation of the application and the convenience of the user even if the communication amount tw is suppressed greatly suppress the communication amount tw. This is where you can expect.

The reason is that the suppression instruction unit 204 transmits a suppression instruction including a suppression parameter having the highest suppression effect to each of the terminal devices 11 to 1n.

The eighth effect of the present embodiment described above is that the amount of communication w suitable for data processing in the server 30 can be suppressed.

The reason is that the following configuration is included. First, the suppression instruction unit 204 transmits a suppression instruction including a suppression parameter that differs for each type of data dk. Secondly, the suppression processing method determination unit 103 and the communication amount suppression unit 102 determine the type of data dk or data ds and perform processing.

<<< Second Embodiment >>>
Next, a second embodiment of the present invention will be described in detail with reference to the drawings. Hereinafter, the description overlapping with the above description is omitted as long as the description of the present embodiment is not obscured.

FIG. 12 is a block diagram showing a configuration of a traffic control system 200 according to the second embodiment of the present invention.

Referring to FIG. 12, the traffic volume suppression system 200 according to the present embodiment replaces the terminal device 50 with the terminal apparatus 10 and the suppression instruction unit 204 as compared with the traffic volume suppression system 100 according to the first embodiment. The suppression instruction unit 601 is included. Further, the communication amount suppression system 200 further includes a suppression processing method storage unit 602 as compared with the communication amount suppression system 100. Further, the terminal device 50 further includes a suppression processing method notification unit 501 as compared with the terminal device 10. Note that the suppression instruction unit 601, the suppression processing method storage unit 602, and the suppression processing method notification unit 501 illustrated in FIG. 12 may be components in hardware units or components divided into functional units of a computer device. There may be. Except for these changes, the configuration is the same as that of the first embodiment, and the same components are denoted by the same reference numerals.

FIG. 13 is a block diagram showing an information processing system including the communication volume suppression system 200 (not shown in FIG. 13) of the present embodiment. The information processing system shown in FIG. 13 includes a plurality of terminal devices 51 to 5n, a monitoring device 60, a server device 30, and a communication network 40.

=== Suppression Processing Method Notification Unit 501 ===
The suppression processing method notification unit 501 transmits a suppression parameter corresponding to the suppression processing method determined by the suppression processing method determination unit 103 to the monitoring device 60.

=== Suppression Processing Method Storage Unit 602 ===
The suppression processing method storage unit 602 of the monitoring device 60 receives the suppression parameter from the terminal 50. Next, the suppression processing method storage unit 602 stores the combination of the suppression parameter (processing ID) and the terminal ID of the terminal 50 in the suppression state list. FIG. 15 is a diagram illustrating an example of the suppression state list 708.

=== Suppression Instruction Unit 601 ===
The suppression instruction unit 601 determines suppression parameters for the terminal devices 51 to 5n stored in the connected terminal storage unit 202. In this case, the suppression instruction unit 601 determines the suppression parameter based on the communication amount w measured by the communication amount monitoring unit 201 and further based on the suppression state list 708 illustrated in FIG. 15. This is executed using the effect list 700. Note that the suppression instruction unit 601 may also use the suppression instruction list 701 shown in FIG. 5 when determining the suppression parameter. The suppression instruction unit 601 may include the suppression processing method storage unit 602 as a part of its configuration.

With the above-described configuration, the suppression instruction unit 601 of the traffic volume suppression system 200 of the present embodiment suppresses transmission to the terminal devices 51 to 5n as compared to the suppression instruction unit 204 of the traffic volume suppression system 100 of the first embodiment. Parameters can be determined faster and more appropriately.

For example, consider a case where a part of the terminal devices 51 to 5n does not execute the traffic amount suppression process even though the suppression instruction unit 601 has transmitted a suppression instruction to the terminal devices 51 to 5n. For this reason, it is assumed that the state where the communication amount w measured by the communication amount monitoring unit 201 exceeds the upper limit (limit value) continues.

In this case, in the first embodiment, after a predetermined time, the suppression instruction unit 204 transmits a suppression instruction to all the terminal devices 51 to 5n so as to execute a more effective communication amount suppression process. . Here, the predetermined time is a predetermined time that is predicted to be the communication amount w below the upper limit value when the terminal devices 51 to 5n execute the communication amount suppression process in response to the suppression instruction. Therefore, the time from when the suppression instruction unit 204 transmits the first suppression instruction to when the suppression instruction is transmitted again for the detection that the communication amount w by the communication amount monitoring unit 201 exceeds the upper limit value is wasted. .

On the other hand, in the present embodiment, the suppression processing method notification unit 501 of the terminal devices 51 to 5n that have not performed the traffic volume suppression processing transmits, for example, a process ID 0 (the suppression processing method is “none”) as a suppression parameter. . When the suppression processing method storage unit 602 receives this suppression parameter, the suppression instruction unit 601 immediately transmits a suppression instruction including a suppression parameter indicating a more effective traffic volume suppression process to the terminal devices 51 to 5n. . In this way, since the suppression instruction unit 601 changes the suppression processing method without waiting for detection that the traffic volume w does not fall below the upper limit value, it is possible to shorten the time taken until the traffic volume w falls below the limit value. It becomes.

Next, the operation of this embodiment will be described in detail with reference to the drawings.

The operation of transmitting data ds from the terminal devices 51 to 5n to the server device 30 is the same as that in the first embodiment shown in FIG.

FIG. 14 is a flowchart showing an operation of generating a suppression instruction in the monitoring device 60 and an operation of determining a suppression processing method in the terminal devices 51 to 5n.

Since steps S301 (first operation) to S308 in FIG. 14 are the same as steps S201 to S208 shown in FIG.

The suppression processing method notification unit 501 transmits the suppression parameter corresponding to the suppression processing method determined by the suppression processing method determination unit 103 in step S308 to the monitoring device 60 (step S309). Then, the processing of the terminal devices 51 to 5n ends.

Next, the suppression processing method storage unit 602 of the monitoring device 60 receives and stores a suppression parameter indicating the suppression processing method (step S310). And the process of the monitoring apparatus 60 returns to step S301. Note that the processing of the monitoring device 60 may end after step S310. In this case, the monitoring device 60 may start the processing from step S301 at regular time intervals.

Next, in the second and subsequent operations of step S301, the suppression instruction unit 601 determines suppression parameters to be transmitted to each of the terminal devices 51 to 5n. In this case, the suppression instruction unit 601 uses the connection terminal list 707 shown in FIG. 3, the suppression effect list 700 shown in FIG. 4, and the suppression instruction list 701 shown in FIG. The suppression parameter is determined based on the suppression state list 708.

The first effect of the present embodiment described above is that the suppression parameter included in the suppression instruction can be determined quickly and appropriately.

The reason is that the following configuration is included. That is, first, the suppression processing method notification unit 501 transmits the suppression parameter determined by the suppression processing method determination unit 103 to the monitoring device 60. Secondly, the suppression processing method storage unit 602 receives and stores the suppression parameter. 3rdly, the suppression instruction | indication part 601 determines the suppression parameter of the suppression instruction | command transmitted next based on the suppression parameter.

<<< Third Embodiment >>>
Next, a third embodiment of the present invention will be described in detail with reference to the drawings. Hereinafter, the description overlapping with the above description is omitted as long as the description of the present embodiment is not obscured.

In the present embodiment, the suppression instruction transmitted from the monitoring device 60 to the terminal devices 51 to 5n includes two types of suppression parameters.

FIG. 16 is a diagram illustrating an example of the suppression instruction 706 in the present embodiment. As illustrated in FIG. 16, the suppression instruction 706 includes a target suppression parameter (processing ID) and an essential suppression parameter (processing ID).

Here, the target suppression parameter specifies a traffic volume suppression process that the monitoring device 20 expects to be executed in the terminal devices 51 to 5n. That is, the target suppression parameter indicates the same as the suppression parameter of the suppression instruction in the first and second embodiments. Accordingly, each of the terminal devices 51 to 5n does not necessarily perform the traffic amount suppression process according to the target suppression parameter depending on the terminal state information. Such a target suppression parameter specifies, for example, a traffic volume suppression process that has a high traffic volume suppression effect but has a large effect on the convenience of the users of the terminal devices 51 to 5n.

On the other hand, the essential suppression parameter specifies a traffic volume suppression process that is defined to be executed at least by the terminal devices 51 to 5n. That is, the terminal devices 51 to 5n execute a traffic amount suppression process having a suppression effect equal to or greater than the suppression effect of the traffic amount suppression process corresponding to the essential suppression parameter regardless of the state of each of the terminal devices 51 to 5n. Such an essential suppression parameter specifies, for example, a suppression processing method that has a low communication volume suppression effect but has a small effect on the convenience of the users of the terminal devices 51 to 5n.

In the present embodiment, the suppression processing method determination unit 103 of the terminal devices 51 to 5n executes the traffic volume suppression process corresponding to the target suppression parameter included in the received suppression instruction as it is or executes the next best traffic volume suppression process. Judge whether to do. In this case, the suppression processing method determination unit 103 makes the determination based on the terminal state information acquired by the terminal state acquisition unit 104.

When it is determined that the next-best traffic volume suppression process is to be executed, the suppression processing method determination unit 103 according to the present embodiment performs a traffic volume suppression process corresponding to at least the essential suppression parameter or a traffic volume suppression process having an equivalent suppression effect. Make a decision to execute. Therefore, unless “None” is designated as the essential suppression parameter, the suppression processing method determination unit 103 determines to execute some kind of communication amount suppression processing.

The operation of the traffic control system 200 in this embodiment differs from the operation of the traffic control system 200 in the second embodiment in the following points. First, the operation of determining a suppression parameter for designating the traffic volume suppression process for the traffic volume tw in the monitoring device 60 is different. Second, the operation of determining the communication amount suppression processing method in the terminal devices 51 to 5n is different.

Specifically, in step S202 (step S302), when the suppression instruction unit 601 determines the suppression parameter based on the communication amount w, in the present embodiment, the essential suppression parameter is determined in addition to the target suppression parameter. To do. The method for determining the target suppression parameter is the same as in the second embodiment. The suppression instruction unit 601 determines, for example, what specifies a traffic amount suppression process having a suppression effect that is half that of the traffic amount suppression process specified by the target suppression parameter as an essential suppression parameter. Moreover, the suppression instruction | indication part 601 may determine the suppression parameter which designates the traffic volume suppression process which has the minimum suppression effect in various traffic volume suppression processes as an essential suppression parameter.

In step S307, when the suppression processing method determination unit 103 changes the suppression processing method to a method other than the suppression processing method specified by the target suppression parameter, in this embodiment, the suppression processing method determination unit 103 A suppression processing method having a suppression effect equal to or greater than that of the suppression processing method specified by the essential suppression parameter is determined.

Next, the effect of this embodiment will be described.

Note that the target suppression parameter and the essential suppression parameter of the suppression instruction 706 illustrated in FIG. 16 are specified by, for example, a reduction amount of the communication amount tw (such as 500 bytes per second) or an upper limit value of the communication amount tw (such as 10 kilobytes per second). May be.

The third embodiment described above has been described as a modification of the second embodiment, but the same modification may be made to the first embodiment. In this case, the configuration and operation are the same as those in the third embodiment described above, in which the monitoring device 60 is suppressed to the monitoring device 20, the terminal devices 51 to 5n are switched to the terminal devices 11 to 1n, and the suppression processing method notification unit 501 is suppressed. Replace with the instruction unit 204.

The first effect of the present embodiment described above is that, when the communication amount w is suppressed, it is possible to prevent the difference in the suppression amount of each communication amount tw between the terminal devices 51 to 5n from becoming too large. It is a point.

The reason for this is that the traffic volume suppression process instructed by the monitoring device 60 to the terminal devices 51 to 5n is the minimum suppression process that the terminal devices 51 to 5n should execute, and the target suppression process that should be executed if possible. It is because it divided into. That is, the reason is that the communication amount tw can be suppressed with a constant forcing force.

The reason is specifically, it includes the following configuration. That is, first, the suppression instruction unit 601 includes the target suppression parameter and the essential suppression parameter in the suppression instruction. Secondly, the suppression processing method determination unit 103 executes a traffic amount suppression process that has a suppression effect that is greater than or equal to the suppression effect of the traffic amount suppression process corresponding to the essential suppression parameter.
