Description

  The present invention relates to a telephone service via the Internet, and in particular, by identifying an incoming call from a business operator who makes a call to an unspecified number of people such as “Wangiri” and controlling the incoming call state, The present invention relates to a terminal device and a server for an Internet telephone that can improve quality.

  In the present invention, the Internet telephone is not limited to an IP (Internet Protocol) telephone that uses the same IP network (Internet) as that used for an application such as WWW, but a part or all of the network. , Including all telephone services using IP network technology (for example, those using an IP network uniquely constructed by a telecommunications carrier or a company).

  “Wangiri” is a misuse of caller ID notification of a telephone call, where a call is made in a calling number notification state and is disconnected by one call. In this case, since the incoming call history remains with the callee, when the callee calls back to the caller, the caller is forced to pay money in the name of “information provision fee”.

  In this case, even if the called party makes a callback, the contract act is not established, so there is no need to pay the information provision fee. Personal information is acquired by means, and it tries to be misrepresented as if a contract has been concluded.

  Since Wangiri performs a one-call disconnect operation on an unspecified number of people, it causes a heavy load on the exchange and may go down in some cases, so at the present time limits the amount of unit time transmission from the same telephone number It is possible to cope with this, but Wangiri itself is not gone.

  However, the conventional Internet telephone has a call control procedure (Peer to Peer) that does not go through the call control server corresponding to the exchange because of its operation mechanism, and there may be communication that is not managed by the service provider. For this reason, the control by such an exchange cannot effectively prevent “Wangiri”.

Recently, as in the techniques described in Patent Document 1 and Patent Document 2, a proposal has been made to have a technique for determining “one-sided” not only on the exchange itself but also on the telephone itself. In other words, an incoming timer is provided on the telephone so that the ringer (ringing sound) is suspended for a certain period of time after the call. Proposals have been made not to stop the display or connect subsequent calls from that telephone number.
JP 2003-298726 A JP 2003-249995 A

  However, since this technique is also handled by the telephone alone, it is determined by the timer even for incoming calls other than “Wangiri”, so it is not necessary for the bona fide incoming call by delaying the ringing of the ringing tone. There was a drawback that would force the waiting time. In addition, with this conventional technology, the information related to “Wangiri” determined by the telephone is limited to only the user of the telephone, and even if many callees are damaged by “Wangiri”, the operator of the Internet telephone cannot grasp it. There was also a problem.

  As described above, since Internet telephones can communicate with each other by call control between terminals, the conventional technology that supports exchanges and individual telephones in fixed telephones and the like is a business that provides Internet telephone services. Can not cope with communication requests from terminal users who are malicious.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and the object thereof is a call control procedure via a call control server corresponding to an exchange and not via a call control server. An Internet phone that has a call control procedure and can respond to malicious communication requests such as “Wangiri” on both the terminal side and the call control server side by taking measures according to the incoming route. It is to provide a telephone terminal device and a server.

  According to the first aspect of the present invention, in an Internet telephone terminal device, a user table for registering identification information of a known caller or relayer, a filter table for registering identification information of an unknown caller, and reception of a call connection request When a timer that measures time, a detection unit that detects identification information of a caller that arrives with a call connection request, and a call connection request of a caller or a relay person registered in the user table, A signal for canceling the connection request within a certain time measured by the timer immediately after arrival of the call connection request when a call connection request of an unknown caller not registered in the user table is received immediately after the tone ringer is activated When the call does not arrive, the call control unit that causes the tone ringer to ring, and immediately after the arrival of the call connection request, the connection is made within a certain time measured by the timer. When a signal to cancel the request arrives, the identification information of the detected originator in the detection unit, characterized by comprising a filter information writing unit to be registered in the filter table.

  According to the invention of claim 1 having such a configuration, in response to a call connection request from a known caller or repeater registered in the user table, the ringing is immediately activated, so that a quick call is made. It becomes possible. On the other hand, in response to a call connection request from an unknown caller, a normal ringing call and “one-time” can be obtained by ringing the tone ringer when a signal for canceling the connection request does not arrive within a certain time measured by the timer. Can be distinguished. And when there is a call of “Wangiri”, by registering the identification information of the caller in the filter table of the terminal, the tone ringer is not ringed in response to a connection request from the same caller, It is possible to take measures such as securing a predetermined waiting time until ringing.

  According to a second aspect of the present invention, in the Internet terminal device according to the first aspect, when the call control unit receives a call connection request of a caller not registered in the filter table, the call connection request When a signal for canceling the connection request does not arrive within a predetermined time measured by the timer immediately after arrival, the tone ringer is activated. When a call connection request of the caller registered in the filter table is received, the tone ringer is Or the tone ringer is activated when a signal for canceling the connection request does not arrive within a fixed time measured by the timer immediately after arrival of the call connection request.

  According to the invention of claim 2 having such a configuration, it is possible to change the correspondence of tone ringer ringing according to whether or not the identification information of the caller is registered in the filter table. It is possible to take higher safety measures for callers who are highly likely to be “Wangiri”.

  According to a third aspect of the present invention, in the terminal device of the Internet telephone according to the second aspect, when the call control unit receives a call connection request of a caller registered in the filter table, the arrival of the call connection request Immediately after the tone ringer is activated after a certain period of time measured by the timer, and the call connection request arrives when the call connection request of the caller not registered in the filter table is received for the certain period of time. Immediately after that, it is set longer than the time when the tone ringer is sounded after a lapse of a predetermined time measured by the timer.

  According to the invention of claim 3 having such a configuration, it is possible to suppress the ringing of the tone ringer for a longer period of time for a caller who has a high possibility of “Wangiri” registered in the filter table. There is no longer a long waiting time for a bona fide caller who has a low possibility of “Wangiri” not registered in the table.

  According to a fourth aspect of the present invention, there is provided an internet telephone terminal device according to the first or second aspect, further comprising an incoming history recording unit, wherein the call control unit is measured by the timer immediately after arrival of a call connection request. When a signal for canceling the connection request arrives within a certain time, information related to the incoming call is deleted from the recording unit of the incoming call history.

  According to the invention of claim 4 having such a configuration, since there is no need to notify the receiver of the terminal device that there has been “Wangiri”, the uncomfortable feeling of the receiver of having received “Wangiri” is eliminated. At the same time, it is possible to reliably prevent a callee's callback for "Wangiri" calls.

  According to a fifth aspect of the present invention, in the terminal device of the Internet telephone according to the first or second aspect, the identification information on the caller side registered in the filter table is transmitted to a server on the network registered in advance. It has the transmission / reception control part.

  According to the invention of claim 5 having such a configuration, since the identification information of the caller who has performed “Wangiri” collected by each terminal device is aggregated in the server, in response to a connection request using the server as a repeater By using this information, the server can block the connection request of the caller who seems to be “one-sided” at the server part.

  The invention of claim 6 is the Internet telephone terminal device according to claim 1, claim 2 or claim 3, wherein caller identification information registered in a filter table provided on another terminal or server is stored. A transmission / reception control unit for receiving via a network is provided, and the filter information writing unit writes the caller identification information received by the transmission / reception control unit in its own filter table.

  According to the invention of claim 6 having such a configuration, it is possible to use the identification information of the caller who performed “Wangiri” recorded on the server or another terminal as information of its own filter table. This makes it possible to determine whether or not the terminal is “one limit” even if it is the first call connection request to the terminal.

  The invention of claim 7 is a server connected to a plurality of Internet telephone terminal devices via a network, each of which includes a filter table for registering identification information of a caller to be monitored, and each of the plurality of terminal devices. A monitoring object document that receives and aggregates identification information on the caller side registered in the provided filter table and registers the identification information in the filter table as a new monitoring object for callers exceeding a preset value And a transmission / reception control unit that transmits the written identification information of the caller to be monitored to the terminal device.

  According to the invention of claim 7 having such a configuration, since it becomes possible to acquire the identification information of the caller who is recognized as “Wangiri” by a plurality of terminals, it is possible to obtain “Wangiri” on the server. It becomes possible to block a call connection request from a highly likely caller, or to notify individual terminals of identification information of a caller who is recognized as “one-handed”. As a result, even a call connection request that does not use the server as a relay person can be blocked on the individual terminal side.

  According to the present invention, by using the present invention, the service provider assists the user's terminal in response to the malicious communication request that the exchange supports in the fixed telephone. Thus, there is an effect that it is possible to add appropriate restrictions and improve the service quality for a bona fide terminal user.

(1) Configuration of the embodiment: FIG.
The configuration of the embodiment of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a network diagram showing an example of an Internet telephone system constituted by an Internet telephone terminal and a server according to the present invention. In the present embodiment, an Internet telephone service server 2 that operates as an exchange and a plurality of terminal devices 3 to 5 are connected to the network 1. Among these, the terminal device 3 is a caller, the terminal device 4 is a bona fide caller, and the terminal device 5 is a malicious caller who performs “Wangiri” or the like. Further, as the server 2, for example, a SIP (Session Initiation Protocol) server that functions as a proxy server is used. However, the Internet telephone of the present invention is not limited to this, and is a server using another signaling protocol. Use is also possible.

  Each of the terminal devices 2 to 4 includes a transmission / reception control unit 11 used for performing communication via the network 1 and a call control unit 12 that analyzes information from the transmission / reception control unit 11 to control start and end of the Internet telephone service. And the user table 13 in which the identification information of the caller and the relayer known to the callee is registered, and whether the other party who wishes to communicate is a malicious Internet telephone terminal device 5 who wants to perform “Wangiri” or the like. When there is a suspicion of an incoming call from the malicious Internet telephone terminal device 5 in the filter table 14 used for identifying the user and the user table 13, the operation of the call control unit 12 is performed for a certain time (for example, 2 to 3 seconds). A timer 15 for holding and a tone ringer 16 used for notifying an incoming call according to an instruction from the call control unit 12 are provided. To have.

  When the call control unit 12 receives a call connection request from a caller or relay who is registered in the user table 13, the call control unit 12 immediately rings the tone ringer 16 and an unknown call that is not registered in the user table 13. When the call connection request of the user is received, the tone ringer 16 is activated when a signal for canceling the connection request does not arrive within a certain time measured by the timer 15 immediately after the arrival of the call connection request. .

  When the call control unit 12 receives a call connection request from a caller not registered in the filter table 14, the call control unit 12 measures a certain time (for example, 5 seconds) measured by the timer immediately after the call connection request arrives. When the signal for canceling the connection request does not arrive, the tone ringer 16 is activated, and when the call connection request of the caller registered in the filter table 14 is received, the timer 15 measures immediately after the arrival of the call connection request. When the signal for canceling the connection request does not arrive within the predetermined time, the tone ringer 16 is activated.

In this case, in this embodiment, when the waiting time until the tone ringer 16 is activated (for example, 5 seconds) is received when a call connection request of a caller not registered in the filter table is received, the call connection request Is set longer than the time (for example, 2 to 3 seconds) when the tone ringer is activated after a predetermined time measured by the timer has elapsed.
In this case, the call control unit 12 may be configured not to sound the tone ringer 16 at all.

  Each of the terminal devices 2 to 4 includes a detection unit 17 that detects identification information of a caller that has arrived along with the call connection request, and a signal that cancels the connection request within a certain time measured by the timer immediately after the arrival of the call connection request. Is provided with a filter information writing unit 18 for registering the identification information of the caller detected by the detection unit in the filter table 14. The detection unit 17 that detects the caller identification information is used by the call control unit 12 to analyze the information from the transmission / reception control unit 11 to control the start and end of the Internet telephone service. By using the identification information as it is, it may be provided integrally with the call control unit 12.

  The transmission / reception control unit 11 transmits the identification information on the caller side registered in the filter table 14 to the Internet telephone service server 2, and the filter provided on the other terminals 4, 5 or the Internet telephone service server 2. The caller identification information registered in the tables 14 and 22 is received via the network 1. Further, the filter information writing unit 18 writes the identification information of the sender in its own filter table 14 when there is a “one-time” action.

  The Internet telephone service server 2 has a function as a normal Internet telephone exchange, and identification information on the caller side registered in the filter table 14 provided in each of the plurality of terminal devices 3 to 5. The transmission / reception control unit 21 for receiving the message, the master filter table 22 for registering the identification information of the caller to be monitored, and the monitoring targets from the terminal devices 3 to 5 received via the transmission / reception control unit 21 A current table 23 is provided for collecting and temporarily accumulating sender identification information.

  In addition, the Internet telephone service server 2 registers the identification information in the master filter table 22 as a new monitoring target for a caller whose total value in the current table 23 exceeds a preset value. 24, and the current table 23 detects that the total value in the current table 23 is less than a preset value by a certain time (a time in which it can be determined as “one-time” action such as one day or one month). Is provided with a timer counter 25 for erasing the identification information (filter information) of the caller to be monitored. The transmission / reception control unit 21 also has a function of transmitting the identification information of the sender to be monitored written in the master filter table 22 to the terminal devices 3 to 5.

(2) Operation of the terminal device ... FIG.
(2-1) Incoming call relayed by a server from a bona fide caller When an incoming call indicating a service start request is received via the network 1 to the callee terminal device 3 used for the Internet telephone service (step 1) If the request is from a bona fide Internet terminal device 4, the incoming call normally arrives via the Internet telephone service server 2 that provides the Internet telephone service. Normally, the identification information of the server 2 is registered in the user table 13 of the called party terminal device 3 when the Internet telephone service is subscribed.

  Therefore, when the IP address information necessary for the call control unit 12 is extracted based on the information confirmed to arrive at the transmission / reception control unit 11, the IP address information is a legitimate server stored in the user table 13. The IP address registration information of the Internet telephone service server 2 is confirmed (YES in step 2). Therefore, the call control unit 12 immediately rings the tone ringer 16 to notify the user of the incoming call (step 10).

(2-2) Direct incoming call from known bona fide caller When there is an incoming call indicating a service start request via the network 1 to the callee terminal device 3 used for the Internet telephone service, the request is When it is from a bona fide Internet terminal device 4 and is made directly, necessary information such as the telephone number on the caller side is obtained from the information whose arrival is confirmed by the transmission / reception control unit 11. (Step 1).

  By comparing this extracted information with the registered information stored in the user table 13, it becomes possible to confirm whether or not it is a known partner. If it is a known partner (YES in step 2), the tone ringer 16 is immediately activated. The incoming call is notified to the user (step 10).

(2-3) Direct incoming call from unknown good-willed caller When there is an incoming call indicating a service start request via the network 1 to the terminal device 3 of the callee used for the Internet telephone service, the request is When it is from the Internet terminal device 4 and is directly performed, the call control unit 12 extracts necessary information such as the telephone number of the caller side from the information confirmed by the transmission / reception control unit 11 (Step 1).

  By comparing this extracted information with the registration information stored in the user table 13, it becomes possible to confirm whether or not the partner is a known partner. When the partner is an unknown partner when confirmed (NO in step 2), If the telephone number indicating the detected destination is referred to in the filter table 14 and if it is not registered (NO in step 3), it waits for the time specified in advance in the timer 15 and cancel information does not arrive during that time The tone ringer 16 is activated to notify the user of the incoming call (step 10).

(2-4) Direct incoming call from an unknown malicious caller not registered in the filter table An incoming call indicating a service start request is received via the network 1 to the terminal device 3 of the callee used for the Internet telephone service. In the case where the request is from the malicious Internet telephone terminal device 5 and made directly, the telephone number on the caller side is required from the information confirmed by the transmission / reception control unit 11 If the information is extracted by the call control unit 12 (step 1) and is confirmed to be a known partner based on the registration information stored in the user table 13 (NO in step 2), the partner The telephone number indicating the destination is referred to in the filter table 14, and if it is not registered (NO in step 3), it waits for the time specified in the timer 15 in advance. (Step 4).

  In this case, since the caller is malicious and the incoming call is an action called “Wangiri” for the purpose of callback, the cancel information arrives at the transmission / reception control unit 11 immediately after the incoming call information arrives (step 6). YES) When the cancel information arrives before the timer 15 expires, the call control unit 12 discards the arrival information and does not ring the tone ringer 16 so that the incoming call is not notified to the recipient. In this case, since the caller is not registered in the filter table (NO in step 7), the malicious caller identification information is registered in the filter table 14 (step 8). The sender identification information is transmitted to the Internet service server 2 using the transmission / reception control unit 11, and the registration operation for the current table 23 is performed.

(2-5) Direct incoming call from an unknown malicious caller registered in the filter table An incoming call indicating a service start request is received via the network 1 to the terminal device 3 of the callee used for the Internet telephone service. In the case where the request is from the malicious Internet telephone terminal device 5 and made directly, the telephone number on the caller side is required from the information confirmed by the transmission / reception control unit 11 Information is extracted by the call control unit 12 (step 1).

  When the registered information stored in the user table 13 confirms whether the partner is a known partner (NO in step 2), the filter table 14 shows a telephone number indicating the detected partner. If registration information is present (YES in step 3), the standby time indicated there (for example, 5 seconds) is designated in the timer 15 and the standby is performed (step 5).

  In this case, since the incoming call is an action called “Wangiri” for the purpose of callback, the cancellation information arrives at the transmission / reception control unit 11 immediately after the incoming call information arrives. For this reason, when the cancel information arrives before the timer 15 expires (YES in Step 6), the call control unit 12 discards the arrival information and does not ring the tone ringer 16 so as not to notify the user of the incoming call. Further, since the identification information of the malicious caller has already been registered in the filter table 14 (YES in step 7), the registration process for the filter table 14 is not performed and the process returns to the standby state.

(3) Operation on the server 2 side ... FIG.
In the Internet telephone service server 2 that provides the Internet telephone service, the Internet telephone terminal device 3 notifies the transmission / reception control unit 21 of the presence of an incoming call that is regarded as a “one-time” action and information on the caller side. If this occurs (step 1), registration is made in the current table 23 (step 2).

  Next, the number of registrations with the same number in the current table 23 is confirmed, and if the total number exceeds the value designated in advance (YES in step 3), it is determined that it is from a one-time operator, and the master filter table 22 is registered (step 4), and the sender information and the number of registrations are deleted from the current table 23 (step 5).

  On the other hand, if the number of registrations with the same number in the current table 23 is less than the specified value (NO in step 3), information about the caller is held until the timer counter 24 expires (for example, for one month), After the predetermined period has elapsed (YES in step 6), the information and registered number for the sender are deleted from the current table 23 (step 5).

  In this way, the connection request from the caller registered in the master filter table 22 is determined to be a connection request from the one-handed service provider, and measures such as rejecting the connection are taken. . In addition, the data of the one-handed service provider registered in the master filter table 22 is, for example, a constant value when the identification information of the malicious caller registered in the filter table 14 is received from each terminal device 3-5. At the timing (YES in step 7), it is transmitted to each of the terminal devices 3 to 5 (step 8).

(4) Other Embodiments The present invention is not limited to the above-described embodiments, and includes the following embodiments.

(a) Regarding the call connection request via the server 2, the tone ringer 16 is immediately activated in the above embodiment as a known caller registered in the user table 13. It is also possible to record only the identification information and not register the identification information of the server 2 as a relay person. In that case, regardless of whether the server 2 relays or not, if the caller identification information is not in the user table 13, the presence or absence of registration in the next filter table 14 is determined, and the length of the waiting time is selected. Processing can be different.

(b) In the above embodiment, in the flowchart of FIG. 2, the identification by the user table 13 is performed before the identification by the filter table 14, but the identification by the filter table 14 is performed first as shown in FIG. You can also. In that case, the waiting time of the tone ringer 16 can be the same regardless of whether or not the filter table 14 is registered.

(c) Transmission / reception of the filter data between the terminal devices 3 to 5 and the server 2 may be exchanged automatically at regular intervals, or at each timing when each terminal rewrites the data in the filter table 14. May be executed.
