Description

  The present invention relates to a crime prevention guidance notification system for suppressing crimes using a telephone.

  In recent years, criminal acts such as wire fraud, etc., where a random telephone call is made based on the obtained personal information and list, and money transfer is requested by deceiving the other party. Although alerts by posters and reports by newspapers, TV, etc. have been made, the techniques have also become more sophisticated and the damage is on the rise.

  In order to protect yourself from these fraudulent acts, it is important to keep an individual alert to transfer fraud, such as doubting the possibility of wire fraud in response to expensive and urgent transfer requests. It is effective to provide a guidance to call attention immediately before starting a call as one of the above.

  As a conventional preventive measure, for example, as described in Patent Document 1 and Patent Document 2 below, a guard method for rejecting an incoming call based on a caller number notified by a number display is generally used. is there. Further, as described in Patent Document 3 and the like, a method of sending a warning message from a telephone has been proposed.

  Conventional countermeasures against crimes such as fraud by telephone have been performed using special telephones such as a telephone with a caller confirmation response function and a telephone with a function of sending a warning message. However, considering the tendency that many of the victims of fraud are elderly people, elderly people do not want to change the phones they have been used to for a long time. Therefore, there is a need to prevent crimes such as fraud by telephone without using special telephones as in the past.

  An object of the present invention is to provide a crime prevention guidance notification system capable of notifying crime prevention guidance using an existing telephone as it is to suppress crimes using the telephone and prompting attention immediately before the start of the call. And

  The crime prevention guidance notification system that solves the above-mentioned problem has a registration information storage unit that pre-registers guidance notification contents to be sent on the condition of attribute information in transmission for the receiving terminal, and attribute information in transmission to the receiving terminal, Checked with the attribute information corresponding to the receiving terminal registered in the registration information storage unit in advance, and the registration information management unit that activates the guidance transmission unit on the condition that it matches, the registration information management unit that is activated, Before connecting a call path between a terminal and the receiving terminal, guidance transmission means for transmitting a voice guidance to the receiving terminal is provided in a telephone exchange system (including a system using an SIP server in an IP phone). It is provided.

  When the callee answers the call, the security guidance is notified before the call starts, so the callee can be alerted and can respond calmly without causing the callee to panic. it can. In addition, since the crime prevention guidance notification system is installed in the equipment on the telephone carrier side, the subscriber can use the existing telephone as it is.

  In this crime prevention guidance notification system, the guidance device is automatically connected to the caller before the call path is connected by equipment on the telephone carrier side. Normally, after a call is made, the call path connection is implemented with the off-hook side of the called party as the trigger, but before connecting the call path, based on the pre-registered conditions such as the caller's phone number and the call time zone Connect the guidance device to the caller.

  The content of the guidance is that there is a lot of money transfer fraud on the receiving side (for example, from 11:00 am to 14:00 pm on the financial institution business day) or that there was actually a fraud case in XX town. Etc. Guidance that gives a sense of alertness and tension before the call is given. On the other hand, guidance for crime prevention is sent to the calling side, such as notifying that the caller's telephone number is recorded by the telephone exchange system on the business side, and that the contents of the call are recorded according to the intention of the called party.

  The embodiment of the crime prevention guidance notification system described below is an embodiment in a telephone exchange system using the technology of the SIP server in the IP network, but it goes without saying that it can be applied to other telephone exchange systems.

  FIG. 1 shows a configuration example of a crime prevention guidance notification system. In FIG. 1, 1 is a calling terminal, 2 is an IP telephone adapter on the calling side, 3 is a SIP server, 4 is a registration information management server, 5 is a guidance device (guidance server), 6 is an IP telephone adapter on the receiving side, and 7 is It is a receiving terminal.

First, the following processing A1 to processing A10 will be described with reference to FIG. 2 to FIG.
(Processing A1): The IP telephone adapter (calling side) 2 that has received the dial signal from the calling terminal 1 generates a SIP_INVITE message and transmits it to the SIP server 3. The SIP server 3 returns a SIP_100 Trying (during transfer) message and relays the SIP_INVITE message to the registration information management server 4 at the same time.

  (Processing A2): The registration information management server 4 inquires for registration information using the recipient telephone number of the received INVITE message as a key, and compares the registered conditions with the parameters in the INVITE message. Based on the comparison result such as the presence / absence of the caller ID notification and the transmission time, it is determined whether or not the guidance notification is to be made to the called party. When notifying the guidance, the guidance ID is determined.

  (Processing A3): The registration information management server 4 transmits a SIP_INVITE message to the IP telephone adapter (incoming side) 6, and the IP telephone adapter (incoming side) 6 instructs the incoming terminal 7 to set up. The IP telephone adapter (incoming side) 6 that has received the completion message from the incoming terminal 7 returns a SIP_183 Session Progress message to the IP telephone adapter (outgoing side) 2.

  The IP telephone adapter (transmitting side) 2 exchanges a confirmation request SIP_PRACK message for the provisional response and the response between the registration information management server 4 and the IP telephone adapter (receiving side) 6. Hereinafter, the sequence of the confirmation request for the provisional response by the SIP_PRACK message is omitted for the sake of simplicity.

  (Processing A4): The IP telephone adapter (incoming side) 6 returns a SIP_180 Ringing message to the IP telephone adapter (outgoing side) 2 when receiving the calling signal from the incoming terminal 7. The IP telephone adapter (calling side) 2 that has received the 180 Ringing message causes the calling terminal 1 to emit a ringback tone.

  (Processing A5): When the called party responds to the calling signal, an off-hook signal is sent from the receiving terminal 7, and the IP telephone adapter (incoming side) 6 uses the session description protocol (codec type, etc.) as a trigger. SIP_200 OK (INVITE) message including SDP) is transmitted. The registration information management server 4 that has received this via the SIP server 3 includes the guidance ID via the SIP server 3 if it is determined that the guidance notification is present in the above-described process (process A2). A SIP_INVITE [2] message is transmitted to the guidance server 5.

  (Process B13): When the guidance to the receiving side is finished, a SIP_BYE [2] message is transmitted from the guidance server 5 to the registration information management server 4, and when the registration information management server 4 receives this, the SIP_200 OK ( Process BYE) [2] A message is returned to the guidance server 5. Also, the registration information management server 4 generates a SIP_UPDATE message and adds the session description protocol (SDP) to update the session description protocol (SDP) for voice calls, and adds the IP phone adapter (incoming side) 6 Send to. Upon receiving the SIP_UPDATE message, the IP telephone adapter (incoming side) 6 updates the session description protocol (SDP), and returns a SIP_200 OK (UPDATE) message including the session description protocol (SDP) to the registration information management server 4. To do. A voice description path from the receiving terminal 7 to the IP telephone adapter (sending side) 2 is opened by updating the session description protocol (SDP).

  (Process B14): When the guidance to the calling side is finished, a SIP_BYE [3] message is transmitted from the guidance server 5 to the registration information management server 4, and when the registration information management server 4 receives it, SIP_200 OK (process BYE) [3] A message is returned to the guidance server 5. Also, the registration information management server 4 transmits the SIP_200 OK (INVITE) message received in the process (process B5) to the IP telephone adapter (calling side) 2. The IP telephone adapter (outgoing side) 2 returns a SIP_ACK (200 OK) message to the IP telephone adapter (incoming side) 6, and at the same time, starts receiving voice and starting transmission of voice. 1 and the incoming call terminal 7 are opened.

Next, a description will be given of an embodiment in which guidance is notified to both sides of outgoing and incoming calls, recording of the caller telephone number and the contents of the call are recorded. A system configuration example of this embodiment is shown in FIG. In this configuration example, a call record server 8 is added to the configuration example shown in FIG.
(About caller telephone number recording)
The caller telephone number recording is performed in the process of (Process B2) of the above-described second embodiment. The registration information management server 4 refers to the registration information using the recipient telephone number of the received INVITE message as a key, and compares the registered conditions with the parameters in the INVITE message. Based on the comparison result such as the presence / absence of the caller telephone number notification and the call origination time, it is determined whether or not to provide the guidance notification to the called party. When notifying guidance, a guidance ID is determined. If the caller telephone number recording condition is met, the caller telephone number existing as a parameter in the INVITE message is recorded and stored in a state that can be referred to by the telephone carrier.

(About call content recording)
The call content recording is realized by setting the destination of the SIP_INVITE message to arrive at the IP telephone adapter (incoming side) 6 via the call recording server 8 in (Processing B3) of the second embodiment. be able to. Subsequent processing is similarly performed via the call recording server 8. When the registration information management server 4 generates a SIP_UPDATE message, the voice packet is set to pass through the call recording server 8 with respect to the voice packet. The voice packet can be copied by the recording server 8 and stored in a state that can be referred to by the telephone carrier.

  FIG. 14 shows a first configuration example of the registration information management server. The registration information management server includes a reception unit 41, a transmission unit 42, a parameter analysis unit 43, a time / day of week management unit 44, a comparison unit 45, a registration information storage unit 46, and a password check unit 47. The receiving unit 41 extracts an INVITE message from the received SIP signal and sends it to the parameter analyzing unit 43.

  The parameter analysis unit 43 extracts attribute information of the calling terminal such as the caller telephone number in the INVITE message and sends it to the comparison unit 45. The registration information storage unit 46 stores guidance notification conditions, and sends the guidance conditions registered for the recipient telephone number to the comparison unit 45. The comparison unit 45 compares the parameter in the INVITE message with the guidance notification condition, determines the presence / absence of the guidance notification, and the type (guidance ID) of the notification notification, and sends it to the transmission unit. The transmission unit transmits an INVITE message in which the guidance ID is set to the guidance server 5.

  The guidance notification condition can be configured so that the subscriber can register and refer to the registration information storage unit 46 from the Web site. At that time, it is preferable to provide a password check unit 47 in order to increase the security of access to the registration information storage unit 46.

  FIG. 15 shows a second configuration example of the registration information management server. In this second configuration example, a caller telephone number recording unit 48 is added to the first configuration example described above. When the comparison unit 45 meets the caller telephone number recording conditions, the caller telephone number recording unit 48 sends and records the call information parameters. The recorded caller telephone number can be referred to only when a special permission is given, such as in the event of an emergency, and can be configured to be automatically deleted after a certain period.

  FIG. 16 shows a specific example of parameters of the SIP_INVITE message. This parameter includes the sender's phone number, the recipient's phone number, information on whether the number is not notified, the carrier information of the calling terminal, billing area information (calling area), terminal identification number (type of calling terminal), etc. Contains information. Among these, parameters used for determining whether or not the conditions for the guidance notification match are extracted.

  FIG. 17 shows an example of a display screen of a Web site for setting guidance condition check items. For example, as a check item, whether the number is not notified, whether the incoming time is 11:00 to 14:00 on weekdays, an incoming call from a mobile phone, or an incoming call from outside the city (whether the billing area is outside the city) ) Whether the type of calling terminal is of the carrier (carrier) A, the carrier (carrier) B, the carrier (carrier) C, the other carrier (carrier), or the sender The item to be checked is set for the items such as whether the telephone number is the designated first number (eg, 03-11112-2222) or the second number (eg, 090-3333-4444). The telephone subscriber can arbitrarily set and register.

  FIG. 18 shows an example of a display screen of a Web site for setting guidance notification contents corresponding to the guidance conditions. For example, when the serial number 09 or 10 of the check item of the guidance condition shown in FIG. 17 described above is matched (the call originates from the designated caller number), the guidance notification can be set not to be performed.

  In addition, when the serial numbers 01 and 02 of the check items in FIG. 17 described above are matched (when the caller telephone number is not notified and the incoming time is from 11:00 to 14:00 on weekdays), the caller side displays “ You can set it to notify you of guidance such as “Because it is a time zone where wire fraud frequently occurs.

  If the serial numbers 01 and 08 of the check items in FIG. 17 described above are matched (when the caller telephone number is not notified and the type of the calling terminal is that of another business operator (carrier)), the caller will receive “ The phone is unknown and non-notified, and is likely to be fraudulent, requiring sufficient caution, etc., and the caller will record the phone number at the request of the customer. Can be set to be notified.

  17 matches the serial numbers 01, 04, and 07 of the check items in FIG. 17 (the caller telephone number is not notified, the incoming call is from outside the city, and the type of the calling terminal is the carrier (carrier) C. ), The caller is informed of a guidance such as “Caller without number from outside the city. The possibility of fraud is high, and sufficient caution is required.” You can set to notify the guidance such as "I will record the contents of the call."

  In addition, when it matches with the serial number 08 of the check item in FIG. 17 described above (the type of the transmitting terminal is that of another carrier (carrier)), guidance such as “From a terminal whose model is unknown” is displayed on the receiving side. Can be set to notify.

  With the above-described crime prevention guidance notification system, it is possible to arouse a warning that “may be a scam” immediately before responding to an incoming call, and it is possible to guide to respond calmly without falling into a panic state. Moreover, since the crime prevention notification system is installed on the telephone carrier side, the telephone subscriber can use the existing telephone as it is.

  In addition, when notification of crime prevention guidance is desired, application conditions for guidance notification may be registered in advance, and guidance notification can be received without performing setting operations each time. It is also possible for a close relative to apply for the application conditions of the guidance notification to a telephone company for an elderly relative living alone who lives far away.

  In addition, by setting the guidance notification not to flow when receiving a call from a reliable caller, it is possible to prevent the feeling of sensation due to the familiarity of the guidance notification from being slowed down, and to call attention only to an actually high-risk incoming call. . In addition, by changing the type of guidance content to be notified depending on conditions, it is possible to prevent habituation of the senses and to increase tension according to the degree of danger.

  In addition, by sending crime prevention guidance to the calling side, it is possible to warn a person who tries to easily commit a crime imitatingly. Moreover, the reuse of illegal terminals (such as prepaid mobile phones) can be suppressed by recording the caller telephone number. In addition, it is possible to maintain evidence and prevent recidivism by recording calls.
