When the communication traffic state monitoring unit 132 determines that the communication traffic state of the core network 402 exceeds a preset threshold, the notification unit 152 notifies the contract communication terminal using the core network 402 to that effect. .
The communication enable / disable determining unit 112 instructs the core network 402 to transfer only the data transmitted from the contract communication terminal to the mail server 500, and the data is not transferred to the mail server 500. In this case, it is determined that the contract communication terminal has failed to communicate. Further, the communication enable / disable determining unit 112 performs communication from the contract communication terminal after the instruction unit 142 instructs the core network 402 to transfer only the data transmitted from the contract communication terminal to the mail server 500. When a communication disabling signal indicating that the communication cannot be performed is transmitted, it is determined that the contract communication terminal has failed to perform communication.

This preferential treatment may be, for example, a service provider providing an optional service paying a predetermined amount to the contract communication terminal, or paying a usage fee from the contract communication terminal for a predetermined period. May be used as long as it can compensate that the contract communication terminal cannot communicate with the contract communication terminal.

Hereinafter, a communication method in the communication system shown in FIG. 8 will be described. FIG. 10 is a sequence diagram for explaining an example of a communication method in the communication system shown in FIG.
The communication traffic state monitoring unit 132 monitors the communication traffic state of the core network 402 used by the communication terminal 202 (step S21). This monitoring periodically monitors contents affecting the processing capability of the core network 402, such as the CPU usage rate in the core network 402 and the amount of communication traffic per unit time. For example, when the communication traffic state monitoring unit 132 monitors the CPU usage rate in the core network 402, the communication traffic state monitoring unit 132 determines whether the CPU usage rate in the core network 402 exceeds a preset threshold. To do. This threshold value is set as a standard for the core network 402 to be in a state generally called “congestion” (for example, a CPU usage rate of 80%). When the communication traffic state monitoring unit 132 determines that the communication traffic state of the core network 402 exceeds a preset threshold, the notification unit 152 uses the core network 402 from the database provided in the monitoring device 102. Among the communication terminals, the contract communication terminal is specified (step S22). The structure of the database provided in the monitoring apparatus 102 is the same as that shown in FIG. Hereinafter, the case where the contract communication terminal identified by the notification unit 152 in step S22 is only the communication terminal 202 will be described as an example.
Then, the notification unit 152 notifies the communication terminal 202 using the core network 402 that the communication traffic state of the core network 402 has exceeded a preset threshold (step S23). The instruction unit 142 instructs the core network 402 to transfer only the data transmitted from the communication terminal 202 using the core network 402 to the mail server 500 (step S24). At this time, the instruction unit 142 instructs the core network 402 to transfer only the data transmitted with the priority process designated from the communication terminal 202 to the mail server 500.
Thereafter, when transmitting data, the communication terminal 202 designates priority processing and transmits data (step S25). Here, when the communication terminal 202 transmits data using a dedicated application started by the communication terminal 202, the transmitted data may be data for which priority processing is designated.
Then, when the data transmitted with the priority processing designated from the communication terminal 202 is received by the core network 402 via the radio base station 300, the core network 402 transfers only this data to the mail server 500 as the destination. (Step S26). That is, for data transmitted without specifying priority processing, the core network 402 does not transfer the data to the mail server 500 even if the destination is the mail server 500.
Thereafter, the communication terminal 202 determines whether or not the transmitted data has been successfully transferred (transmitted) (step S27). This is performed by confirming whether the data transmitted by the communication terminal 202 has arrived at the destination. This confirmation method is not specified. If the communication terminal 202 determines that the transmitted data has not been successfully transferred (transmitted), the communication terminal 202 transmits a communication disable signal indicating that communication has failed to the monitoring apparatus 102 via the radio base station 300. (Step S28). Then, the preferential treatment grant part 122 gives preferential treatment to the communication terminal 202 (step S29). At this time, the preferential treatment grant unit 122 may give the preferential treatment to the communication terminal 202 after notifying the communication terminal 202 of the preferential treatment.

As described above, when the communication network used by the contract communication terminal that has contracted the predetermined optional service is congested, the communication network preferentially transfers the data transmitted from the contract communication terminal. If the data transmitted from the contract communication terminal fails to be transferred with priority, the contract communication terminal is given preferential treatment, so the user of the contract communication terminal can use the communication terminal with peace of mind. .

Below, the communication method in the communication system shown in FIG. 11 is demonstrated. FIG. 13 is a sequence diagram for explaining an example of a communication method in the communication system shown in FIG.
The communication traffic state monitoring unit 133 monitors the communication traffic state of the core network 403 used by the communication terminal 203 (step S41). This monitoring periodically monitors contents that affect the processing capability of the core network 403, such as the CPU usage rate in the core network 403 and the amount of communication traffic per unit time. For example, when the communication traffic state monitoring unit 133 monitors the CPU usage rate in the core network 403, the communication traffic state monitoring unit 133 determines whether the CPU usage rate in the core network 403 exceeds a preset threshold. To do. This threshold value is set as a standard for the core network 403 to be in a state generally called “congestion” (for example, CPU usage rate 80%). When the communication traffic state monitoring unit 133 determines that the communication traffic state of the core network 403 has exceeded a preset threshold, the notification unit 153 uses the core network 403 from the database included in the monitoring device 103. Among the communication terminals, the contract communication terminal is specified (step S42). The structure of the database provided in the monitoring apparatus 103 is the same as that shown in FIG. Hereinafter, the case where the contract communication terminal identified by the notification unit 153 in step S42 is only the communication terminal 203 will be described as an example.
Then, the notification unit 153 notifies the communication terminal 203 using the core network 403 that the communication traffic state of the core network 403 has exceeded a preset threshold value (step S43). In addition, the instruction unit 143 instructs the core network 403 to transfer only data transmitted to the communication terminal 203 using the core network 403 to the radio base station 300 (step S44). At this time, the instruction unit 143 instructs the core network 403 to transfer only the data transmitted to the communication terminal 203 that has designated priority processing to the radio base station 300.
Thereafter, the communication terminal 203 designates priority processing for the core network 403 (step S45). Here, the communication terminal 203 may designate priority processing for the core network 403 when receiving a predetermined operation performed by the user using a dedicated application activated on the communication terminal 203. . This designation may be made via the monitoring device 103.
Thereafter, when the data transmitted from the mail server 500 to the communication terminal 203 is received by the core network 403 (step S46), the core network 403 transmits this data to the communication terminal 203 via the radio base station 300. Transfer (step S47). That is, the core network 403 does not transfer data transmitted to a communication terminal that has not designated priority processing.
Thereafter, the communication terminal 203 determines whether or not the data transmitted from the mail server 500 has been received (step S48). This is performed by confirming whether data has been transmitted from the communication terminal as the transmission source and whether the data has been received by the communication terminal 203. This confirmation method is not specified. If the communication terminal 203 determines that the data has not been successfully received, the communication terminal 203 transmits a communication disable signal indicating that communication could not be performed to the monitoring apparatus 103 via the radio base station 300 (step S49). . Then, the preferential treatment giving unit 123 gives preferential treatment to the communication terminal 203 (step S50). At this time, the preferential treatment giving unit 123 may give the preferential treatment to the communication terminal 203 after notifying the communication terminal 203 of the preferential treatment.

As described above, when the communication network used by the contract communication terminal that has contracted the predetermined optional service is congested, the communication network preferentially transfers the data transmitted to the contract communication terminal. If the data sent to the contract communication terminal fails to be transferred with priority, the contract communication terminal is given preferential treatment, so the user of the contract communication terminal should use the communication terminal with peace of mind. Can do.
