  In the operation sequence diagrams shown in FIGS. 9 to 12, the SMS filter device 34 checks the received SMS text for the presence of a telephone number, URL, or specific characters. The sender is notified via the SMS delivery device 32 that the SMS has been blocked. Here, the same process is performed even when it is a junk mail, and the billing process is executed when the SMS is received. Therefore, deterrence against the junk mail sender can be expected.

  By the way, according to the above-described embodiment of the present invention, the transmitting / receiving terminal 1 that has transmitted the short message transmits a fixed short message from the SMS filter device 34 at the same time or before the notification of the transmission of the transmitted short message. There is a possibility of receiving. At this time, the reception of the fixed short message is rejected and accumulated in the SMS delivery device 32, and the fixed short message may be delayed and delivered at the retransmission opportunity managed by the SMS delivery device 32. For this reason, the SMS filter device 34 of the present invention includes an SMS transmission timing control unit 346 with a built-in timer, and the SMS transmission timing control unit 346 performs competitive reception of a short message for delivery notification and a fixed short message. Is avoiding.

FIG. 16 is a sequence diagram showing the transmission timing of the short message delivery notification and the fixed short message, which is realized for the above-described contention avoidance. Here, description will be made with reference to filter control (filter registration: valid) by a short message from the packet network 4.
First, a short message (SMS in the figure) is transmitted from the sending / receiving terminal 1 to the filter registrant (S161). This short message body includes a URL, a telephone number, or specific characters designated by the user, and is received by the SMS filter device 34 (S162).

The SMS filter device 34 receives this short message at the SM transmission / reception unit 342 and transfers control to the function execution control unit 343. The function execution control unit 343 recognizes that the message is a short message to the filter registrant, and checks the text to determine that it is a filter target.
As a result, the function execution control unit 343 discards the short message, and notifies the fact that the discard has occurred via the SMS gateway 31 via the SMS gateway 31 by a fixed short message generated and transmitted by the fixed SM generation / transmission unit 344. Is distributed to the calling / receiving terminal 1 that has transmitted the message.

At this time, the SM transmission timing control unit 346 determines the delivery timing of the fixed short message after the delivery notification is returned by the SM transmission / reception unit 342 (S163, S164) and after a predetermined time is measured (about 0 to 20 seconds) by the built-in timer. Control. As a result, it is possible to reliably deliver a fixed short message to the caller once via the SMS delivery device 32 (S165, S166, S168).
As a result, on the sender side, reception with a certain interval guaranteed by reply of delivery notification and fixed short message delivery becomes possible (S167: reception confirmation OK). Therefore, in a series of short message control (S162: URL, short message transmission with telephone number → filter check → S165: block notification by fixed short message delivery), the sender is surely notified in real time that the message is blocked by the filter. be able to.

  As described above, in the present invention, the SMS filter device 34 receives a short message transmitted from the calling / receiving terminal 1 via the packet network 4 or the telephone line network 5 and performs delivery notification for confirmation of reception. When it is confirmed that the received short message is a short message addressed to the calling / receiving terminal 1 for which filter registration has been made in advance, a filter check is performed by determining specific characters in the text of the received short message, According to the result of the filter check, a fixed short message is generated and sent back to the outgoing / incoming terminal 1, which makes it possible to realize incoming call rejection for spam mail.

In addition, the present invention simplifies the functions related to filtering by simply operating the calling / receiving terminal 1 and transmitting a short message to a representative telephone number assigned for registration, cancellation, and status confirmation. Thus, it is possible to construct an environment in which short message filtering can be easily registered.
Further, according to the present invention, when the SMS filter device 34 once receives the junk mail, the sender is charged, and thus the malicious sender can be expected to suppress the junk mail transmission. In addition, by sending a fixed short message after a predetermined time has elapsed after the reply for the delivery notification by the short message, the reception of the fixed short message after the delivery notification at the calling / receiving terminal 1 is ensured. The contention reception on the sender side of the short message for delivery notification by the filter device 34 and the fixed short message is avoided.

  The procedure executed by each of function setting unit 341, SM transmission / reception unit 342, function execution control unit 343, fixed SM generation / transmission unit 344, charging processing unit 345, and SM transmission timing control unit 346 shown in FIG. The SMS filter device of the present invention can be realized by recording the program on a readable recording medium, causing the computer system to read and execute the program recorded on the recording medium. The computer system here includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.
The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
