FIG. 5 is a flowchart showing processing executed by the communication control device 10 according to the embodiment of the present invention. The process shown in FIG. 5 is started when there is a voice call connection request from the communication terminal device of the transmission source. The communication terminal device of the transmission source transmits the identification information of the own device and the identification information of the communication terminal device of the transmission destination to the communication control device 10 together with the connection request for the voice call. In step S101, the monitoring unit 101 of the communication control device 10 determines whether or not the identification information of the communication terminal device of the transmission source and the identification information of the communication terminal device of the transmission destination are registered in the restricted list. It is determined whether or not the communication connection between the original communication terminal device and the destination communication terminal device is restricted. When it is determined that the communication connection of these communication terminal devices is subject to the restriction (YES), the process of FIG. 5 ends. On the other hand, if it is determined that the communication connection of these communication terminal devices is not a restriction target (NO), the process branches to step S102.

In step S102, the communication control unit 102 establishes communication between the source communication terminal device and the destination communication terminal device. In step S103, the analysis unit 103 acquires the voice data transmitted by the communication terminal device of the transmission source. In step S104, the analysis unit 103 analyzes the voice data and determines whether the voice data matches the communication regulation condition.

If the voice data of the communication terminal device of the transmission source does not match the communication regulation condition (NO), the process of FIG. 5 ends. On the other hand, if the voice data of the source communication terminal device matches the communication regulation condition (YES), the process branches to step S105. In step S105, the communication control unit 102 disconnects communication between the source communication terminal device and the destination communication terminal device. In step S106, the registration unit 104 adds the identification information of the communication terminal device of the transmission source and the identification information of the communication terminal device of the transmission destination to the restriction target list, and the processing of FIG. 5 ends.

In one embodiment of the present invention, the communication control device 10 analyzes the voice data regarding the voice call of the communication terminal device of the transmission source, and determines whether or not the voice data matches the communication regulation condition. When the voice data matches the communication regulation condition, the communication control device 10 disconnects the communication between the communication terminal device of the transmission source and the communication terminal device of the transmission destination, and the identification information of these communication terminal devices is regulated. Register in the list. Then, when there is a voice call request from the communication terminal device, the communication control device 10 registers the identification information of the source communication terminal device and the identification information of the destination communication terminal device in the restricted list. If the communication connection between the source communication terminal device and the destination communication terminal device is restricted, the communication between the source communication terminal device and the destination communication terminal device is not established. .. As a result, a request for a voice call to a specific destination communication terminal device is made from the source communication terminal device that has transmitted the voice data that matches the communication regulation condition, that is, the communication terminal device used by an unauthorized user. If there is, it is possible to prevent the communication between the source communication terminal device and the destination communication terminal device from being established, and regulate the voice call by the communication terminal device used for the unauthorized voice call. be able to. This means that if a communication terminal device of an unauthorized user illegally accesses the communication control device 10 via the Internet 30 and impersonates the communication terminal device of the authentic user, In order to restrict only the voice call between the specific destination communication terminal device, the voice call between the authentic user communication terminal device and the communication terminal device other than the specific destination communication terminal device. It is useful because it does not regulate

Further, the communication control device 10 uses the voice pattern extracted from the voice data transmitted by the communication terminal device of the transmission source to determine whether or not the voice data matches the communication regulation condition. That is, the communication control device 10 can determine whether or not the voice data matches the communication regulation condition, by using the voice pattern included in the voice data transmitted by the communication terminal device of the unauthorized user. Since a specific voice pattern may be repeatedly reproduced in a voice call by a communication terminal device of an unauthorized user, the communication control device 10 effectively uses the specific voice pattern to make an unauthorized voice call. Can be regulated.

Further, the communication control device 10 can regulate a voice call by a communication terminal device used for an unauthorized voice call regardless of whether the destination communication terminal device is located inside or outside the country. This is particularly useful because illegal voice calls using international calls, which have higher call charges than domestic calls, can be regulated and the amount of damage caused by illegal calls can be suppressed.
