Description

  The present invention relates to a communication system, a communication method, and a computer program.

  Annoying phone crimes are the most familiar crimes and do not know when they will be damaged. In recent years, there are some malicious things that cause tremendous financial damage such as wire fraud, and attention has been made in various places, and countermeasure products have been released.

  A general nuisance call countermeasure method will be described with reference to FIG.

  FIG. 13 is a block diagram illustrating the configuration of a communication system in which measures against unwanted calls are taken.

  The communication system includes a server 100, terminals 101 and 111, and telephones 102, 112, and 121.

  Server 100 is on the same network 501 as terminals 101 and 111 and telephone 121, and is communicably connected. The server 100 maintains a list of telephone numbers (phone number list) specified as the sender of the nuisance call.

  Terminals 101 and 111 are dedicated terminals that implement a function for preventing unwanted calls.

  The telephone 102 is connected to the terminal 101. Similarly, the telephone 112 is connected to the terminal 111.

  Terminals 101 and 111 receive a telephone number list of nuisance calls from server 100.

  When a call is received from a telephone number included in the received telephone number list, the terminals 101 and 111 alert the user with the color of the light displayed on the terminals 101 and 111.

  Further, it is assumed that the telephone 102 receives an incoming call from the telephone 121 that determines that the user of the telephone 102 is a nuisance call. In that case, the user presses a button on the terminal 101. As a result, the server 100 adds the incoming telephone number (the telephone number of the telephone 121) to the telephone number list of the nuisance calls registered in its own device.

  As techniques for taking measures against nuisance calls using a dedicated terminal in this way, for example, there are the following documents.

  Japanese Patent Application Laid-Open No. 2004-133620 discloses a technique for defining a nuisance call condition in a nuisance call compatible device, searching for incoming call history information corresponding to this condition, and rejecting an incoming call from the corresponding caller.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing a configuration of a communication system according to the first embodiment of the present invention.

  The communication system according to the present embodiment includes a communication terminal 10, a home gateway (hereinafter also referred to as HGW) 20, and a server 30.

  The communication terminal 10 is communicably connected to the home gateway 20.

  The home gateway 20 and the server 30 are communicably connected via a network 50 such as an Internet connection.

  Home gateway 20 includes a control unit 21 and a white list recording unit 22.

  The white list recording unit 22 records a telephone number that responds when an incoming call arrives at the communication terminal 10 (that is, a telephone number that is acceptable even if the user responds).

  The control unit 21 inquires of the server 30 about the telephone number received by the communication terminal 10.

  Further, the control unit 21 adds and deletes telephone numbers recorded in the white list recording unit 22.

  The server 30 includes a control unit 31, a black list recording unit 32, and a log recording unit 33.

  The black list recording unit 32 stores information representing a telephone number that is not desired to be answered when an incoming call is received at the communication terminal 10.

The control unit 31 determines whether the telephone number inquired from the home gateway 20 is recorded in the black list recording unit 32 . The control unit 31 notifies the control unit 21 of the determined result.

In addition, the control unit 31 stores in the log recording unit 33 that the inquiry has been received. When the log stored in the log recording unit 33 satisfies a predetermined condition, the control unit 31 adds the telephone number to the black list recording unit 32 .

  In the present embodiment described above, the log recording unit 33 may be omitted if it is not necessary to update the content recorded in the black list recording unit 32.

  In the above-described embodiment, the white list recording unit 22 may be omitted if it is not necessary to record a telephone number that does not cause a problem even if the user responds.

  As described above, the first embodiment has an effect that countermeasures against nuisance calls can be performed without using a dedicated terminal for nuisance call countermeasures and without requiring manual operation by the user. The reason for this is that the communication system according to the present embodiment uses the user's hand by determining a phone call that may be statistically annoying on the server 30 (hereinafter also referred to as annoying phone call). This is because it is possible to judge annoying calls.

  Further, according to the present embodiment, the blacklist management and alerting to the user can be realized only by communication between the home gateway 20 and the server 30, and therefore the telephone exchange that the user cannot change freely There is no need to change the settings or introduce a dedicated terminal to prevent unwanted calls.

<Second Embodiment>
Next, a second embodiment based on the communication system according to the first embodiment described above will be described.

  FIG. 2 is a block diagram showing a configuration of a communication system according to the second embodiment of the present invention.

  The communication system of this embodiment includes a server 200, HGWs 201, 211, and 221, telephones 202, 212, 222, and a telephone 231.

  The server 200 is connected to the same network 502 as the HGWs 201, 211 and 221 and the telephone 231.

  The HGWs 201, 211, and 221 are devices that are installed between a network such as the Internet connection and a terminal such as a personal computer, a digital home appliance, or a telephone in the home, and transmit and receive information.

  The telephone 202 is connected to the HGW 201, the telephone 212 is connected to the HGW 211, and the telephone 222 is connected to the HGW 221.

  The server 200 acquires telephone information from all HGWs (201, 211, 221) on the network in advance. The information is judged statistically, and a blacklist is created by listing telephone numbers that may be nuisance calls (hereinafter also referred to as nuisance suspicious calls).

  When there is an incoming call from the telephone 231 to the telephone 202 connected to the HGW 201, the HGW 201 transmits the telephone information to the server 200 in order to confirm whether or not the telephone 231 is a suspicious telephone. Inquire.

  The server 200 confirms whether the telephone number of the telephone 231 inquired from the HGW 201 is included in the black list, and returns the result to the HGW 201.

  Based on the reply from the server 200, the HGW 201 determines whether the telephone 231 is a suspicious telephone. If the call is a nuisance suspicious call, the HGW 201 calls attention by voice guidance when the user lifts the handset (that is, performs an operation to make a call on the telephone 202).

  FIG. 3 is a block diagram showing the configuration of the HGW of the communication system according to the second embodiment of the present invention.

  As shown in FIG. 3, the HGW (201, 211, 221) includes a VoIP (Voice over Internet Protocol) control unit 401, a connection control unit 402, a hash generation unit 403, a server communication control unit 404, and an inquiry history. A recording unit 405, a guidance reproduction unit 406, a white list management unit 407, and a white list recording unit 408 are included.

  The VoIP control unit 401 controls the VoIP module. The HGW (201, 211, 221) obtains a telephone number and name information for number display, detects a telephone state (on-hook or off-hook), and controls a connection path of a call through the VoIP control unit 401. .

  When there is an incoming call, the connection control unit 402 refers to the inquiry history recording unit 405 based on information representing the incoming telephone number in the VoIP control unit 401. When the inquiry history recording unit 405 has no information indicating the incoming telephone number, the connection control unit 402 transmits the hash value of the incoming telephone number to the server communication control unit 404 via the hash generation unit 403.

  The hash generation unit 403 receives the incoming telephone number from the connection control unit 402 and generates a hash value. The generated hash value is transmitted to the server communication control unit 404 in order to inquire the server 200 whether or not it is a suspicious telephone call.

  The server communication control unit 404 receives the hash value generated based on the incoming telephone number from the hash generation unit 403, and controls communication with the server 200 on the network.

  The server communication control unit 404 acquires information representing the matching result between the incoming telephone number and the black list from the server 200 via the network. The server communication control unit 404 transmits the acquired information to the connection control unit 402.

  The connection control unit 402 obtains a blacklist collation result, and notifies the guidance reproduction unit 406 to the effect when the user needs to be alerted.

  The white list recording unit 408 stores, as a white list, telephone numbers that the user has registered as not telephone numbers of nuisance calls.

  The white list management unit 407 receives from the VoIP control unit 401 a notification that the telephone number for white list editing has been dialed from the telephone connected to the HGW (201, 211, 221). After the reception, the white list management unit 407 controls the guidance reproduction unit 406 and the VoIP control unit 401, and provides a function of editing the white list by voice guidance and a push signal.

  FIG. 4 is a block diagram showing the configuration of the server of the communication system according to the second embodiment of the present invention.

  As shown in FIG. 4, the server 200 includes a black list collation unit 301, a black list addition determination unit 302, a black list deletion determination unit 303, a black list recording unit 304, and an inquiry log recording unit 305.

  The black list recording unit 304 stores a telephone number that may be a nuisance call as a black list.

  The blacklist collation unit 301 acquires a hash value received from the HGW (201, 211, 221) via the network. The blacklist collation unit 301 reads the blacklist from the blacklist recording unit 304, collates it with the acquired hash value, and returns the result to the HGW (201, 211, 221).

  Further, the blacklist collation unit 301 stores the hash value for which the inquiry has been made in the inquiry log recording unit 305 together with the inquiry time.

  The blacklist addition determination unit 302 counts the number of inquiries within a certain past period for each hash value. When the number of times exceeds a predetermined threshold, the black list addition determination unit 302 adds the hash value to the black list stored in the black list recording unit 304. When adding, the blacklist addition determining unit 302 records the time at the time of addition as an update time in the blacklist in association with the hash value. If the hash value has already been registered in the black list, the black list addition determination unit 302 rewrites (updates) the update time associated with the hash value to the update time of the black list.

  The black list deletion determination unit 303 confirms the update time of the black list for each hash value from the black list stored in the black list recording unit 304, and deletes those that have passed a certain time.

  FIG. 5 is a sequence diagram showing an outline of operation when an incoming call is made to a telephone connected to the HGW in the communication system according to the second embodiment of the present invention.

  With reference to FIG. 5, an operation when the telephone 202 receives a call from the telephone 231 will be described.

  First, when calling the telephone 202, the telephone 231 receives the incoming call to the HGW 201 (step S11).

  The HGW 201 performs a frequency calculation for counting the number of times the same number (here, the telephone number of the telephone 231) is inquired of the server 200 as to whether or not it is a nuisance suspicious telephone call within a preset period (step S12). .

  As a result of the frequency calculation (step S12), if the inquiry has never been made within the set period, the HGW 201 calculates a hash value based on the incoming telephone number (step S13). The HGW 201 transmits the obtained hash value to the server 200 and inquires whether the telephone is a suspicious telephone (step S14).

  The server 200 checks the hash value transmitted for the suspicious telephone inquiry (step S14) with the black list (step S15). The server 200 returns the collated result to the HGW 201 (step S16). The reason why the hash value, not the telephone number itself, is used as data to be transmitted is to prevent the HGW 201 itself from sending personal information to the outside.

  As a result of the frequency calculation (step S <b> 12), when the inquiry has already been made within the set period, the HGW 201 acquires the black list collation result from the inquiry history recording unit 405. By using the acquired collation result, the HGW 201 does not make an inquiry to the server 200. As a result, it is possible to prevent a malfunction in which a telephone number frequently calling a specific telephone is registered in the black list.

  The HGW 201 obtains a collation result between the other party's telephone number and the black list, and then a list (hereinafter referred to as a white list) in which telephone numbers that the user has of the HGW 201 do not need to call are registered. Verification (step S17) is performed and the telephone 202 is called (step S18).

  When the HGW 201 detects an off-hook (step S19) in the telephone 202, if it matches the black list and does not match the white list, it does not connect to the telephone 231 and makes a call with the telephone 202 of the telephone 202 once. Are alerted by automatic voice (step S20). Thereafter, the telephone 202 is connected to the telephone 231 (step S21).

  The white list is set after the call ends. The procedure is as follows. When a telephone number is dialed from the telephone 202 to the telephone number for white list editing set in the HGW 201 (step S22), the guidance is reproduced (step S23), and the user sets the push signal (step S24) according to the guidance. Realized by branch selection.

  The black list 508 is generated based on the suspicious telephone inquiry (507) history from the HGW 201 using, for example, a statistical method. This process is performed, for example, by the server 200 at regular intervals.

  Next, the operation of the HGW 201 when receiving an incoming call from the telephone 231 to the telephone 202 will be described with reference to FIG.

  FIG. 6 is a flowchart showing processing when an incoming call is received from the HGW in the communication system according to the second embodiment of the present invention.

  First, upon receiving an incoming call addressed to the telephone 202 from the telephone 231, the HGW 201 confirms the number of nuisance suspicious telephone inquiries made within a unit time with the telephone number of the telephone 231 (step S 31).

  If no suspicious telephone inquiry has been made within the unit time (“Yes” in step S31), the HGW 201 generates a hash value based on the telephone number of the telephone 231 (step S32). Based on the generated hash value, the HGW 201 makes a suspicious telephone inquiry to the server 200 (step S33), and obtains a collation result with the black list. At this time, communication with the server 200 is preferably performed by secure communication such as SSL (Secure Sockets Layer). The HGW 201 additionally stores the obtained collation result in the inquiry history recording unit 405 in the HGW 201.

  If the inquiry is made within the unit time (“No” in step S31), the HGW 201 does not make an inquiry to the server 200 again. The HGW 201 acquires the black list collation result from the inquiry history recording unit 405 (step S34). The HGW 201 limits the number of times of communication with the server 200 per unit time. Thereby, in this embodiment, it is possible to prevent malfunctions in which frequent calls from a specific phone are registered in the black list. In addition, the amount of communication between the HGW 201 and the server 200 can be suppressed.

  If the incoming telephone number (the telephone number of the telephone 231) is included in the black list (“Yes” in step S35) and further not included in the white list (“No” in step S38), the HGW 201 calls the telephone 202 ( Step S39). Then, after detecting off-hook (step S40), the HGW 201 once terminates the call path on the telephone 202 side at the HGW 201 (step S41). The HGW 201 alerts the user of the telephone 202 with an automatic voice that it is a suspicious telephone call (step S42), and then connects the other party's telephone 231 with the call path (step S43).

  If the incoming telephone number is not included in the black list (“No” in step S35) or included in the white list (“Yes” in step S38), the HGW 201 calls the telephone 202 (step S36), After the off-hook detection (step S37), the call path between the telephone 202 and the telephone 231 is connected (step S43).

  Next, processing for editing a white list stored in the HGW (201, 211, 221) will be described.

  In whitelist editing using a telephone, a user selects a menu by pressing a push signal on the telephone according to voice guidance. The user can add and delete numbers from the white list. When adding a telephone number, the user can select a method of selecting the telephone number from an incoming call history recorded by the HGW (201, 211, 221) or a method of inputting an arbitrary telephone number. On the other hand, when deleting a telephone number from the white list, the user selects and deletes the telephone numbers registered in the white list stored in the HGW (201, 211, 221) in the order of registration.

  FIG. 7 is a view for explaining a voice guidance reproduction image at the time of whitelist editing operation according to the second embodiment of the present invention.

  First, when the user calls a phone number for editing the white list, the first voice guidance 701 is played.

  For example, when the telephone number that has been received second from the end is registered in the white list, the user presses the button <1> on the telephone according to the first voice guidance 701. Next, since a voice guidance 702 for selecting a registration method for inquiring whether an arbitrary number is registered or a number is selected from an incoming call history is registered, the user presses the button <1> on the telephone. Then, each time the <2> is pressed, the registration confirmation voice guidance 703 for selecting and reading out the incoming call history remaining in the HGW (201, 211, 221) in a descending order flows. By pressing <1> after pressing, the second incoming phone number from the end can be added to the white list. At this time, a voice guidance 704 for completing registration flows.

  When the user wants to register an arbitrary telephone number, the user presses <2> when the registration method selection voice guidance 702 is played. As a result, a voice guidance 705 for promoting number input flows. The user can register the number by inputting the number to be registered. At this time, a voice guidance 704 for completing registration flows.

  When deleting the third telephone number registered in the white list, the user presses <2> according to the first voice guidance 701. Next, each time <2> is pressed, a deletion confirmation voice guidance 706 is played which sequentially selects and reads out the phone numbers registered in the white list. After the user presses <2> twice, By pressing <1>, the third telephone number registered in the white list can be deleted. At this time, a voice guidance 707 for completion of deletion flows.

  Next, the operation of updating the black list in the server 200 will be described with reference to FIGS.

  FIG. 8 is a diagram for explaining an inquiry log recording unit according to the second embodiment of the present invention. The inquiry log recording unit 305 includes an inquiry time and a hash value. That is, the inquiry time and the hash value are associated in the inquiry log recording unit 305 as shown in the table conceptually shown in FIG.

  The server 200 records the hash value received from the HGW (201, 211, 221) and the inquiry time in the inquiry log recording unit 305 as a log.

  The server 200 obtains the number of inquiries per unit time based on the log at predetermined time intervals as shown in FIG. FIG. 9 is a diagram illustrating the number of inquiries per unit time according to the second embodiment of the present invention. The number of inquiries per unit time includes a hash value and Counts (count). That is, it is assumed that the hash value and Counts (count) are associated as shown in the table conceptually in FIG. 9 in the number of inquiries per unit time. The server 200 extracts the logs within the unit time from the inquiry log recording unit 305, counts the number of times the inquiry is made for each hash value, and obtains the count.

  Next, the server 200 registers, in the black list, hash values that exceed the threshold of the number of inquiries per unit time among the obtained counts. FIG. 10 is a diagram illustrating a black list according to the second embodiment of the present invention. The black list includes a hash value and an update date / time. The update date / time is the latest date / time when the count exceeds the threshold. The server 200 records the update date and time in association with the hash value whose count exceeds the threshold at the number of inquiries per unit time.

  An expiration date is set for a period during which the hash value is registered in the black list. For example, the server 200 deletes the hash value, which is the update date and time before a predetermined period, from the black list. As a result, for example, even if a certain telephone number is once registered in the black list, when the user of the telephone number changes, it is possible to prevent the telephone number from being continuously registered in the black list. It becomes possible.

  As described above, the second embodiment has an effect that it is possible to take a nuisance call countermeasure without using a dedicated terminal for nuisance call countermeasures and without requiring a user's manual operation.

  The reason is that the communication system according to the present embodiment can determine annoying suspicious telephone call without user intervention by statistically determining nuisance suspicious telephone call by the server 200.

In addition, since only the communication between the HGW (201, 211, 221) and the server 200 realizes alerting to the user from the blacklist management, the setting change of the telephone exchange and the nuisance call that the user cannot change freely are realized. It is not necessary to introduce dedicated terminals for countermeasures.
<Third Embodiment>
Next, a third embodiment based on the communication system according to the second embodiment described above will be described.

  In the second embodiment, a user is alerted to annoying suspicious phone calls by voice guidance when the handset is picked up. However, the method of alerting the user is not limited to this. As a third embodiment, a method in which the HGW changes telephone information and name information used for the number display will be described.

  FIG. 11 is a sequence diagram showing an outline of operation when a call is received by a telephone connected to the HGW in the communication system according to the third embodiment of the present invention.

  A case will be described as an example where an incoming call is received from a telephone 902 (not shown) to a user's telephone 900 (not shown) communicably connected to the HGW 901 (not shown).

  Since the HGW 901 matches the telephone number of the other party's telephone 902 (not shown) with the white list (step S57), the operation is the same as in the second embodiment, and the subsequent operation will be described.

  If the telephone number of the telephone 902 is on the black list and not on the white list, the HGW 901 changes the telephone number and name information to be set (step S58). Then, the HGW 901 notifies the user's telephone 900 of the changed telephone number and name information (step S59).

  After notifying the telephone number and name information (step S59), the HGW 901 calls the user's telephone 900 (step S61). After detecting the off-hook (step S62), the HGW 901 connects the call path between the telephone 900 and the telephone 902 (step S63).

  When the telephone 900 receives a call from the other party (step S60), the information rewritten by the HGW 901 is displayed on the number display. The user can pay attention to annoying suspicious calls by displaying or reading out phone numbers and name information (step S61).

  The change of the telephone number and the name information is performed, for example, by the user performing an operation of making a call to a special telephone number for editing the change rule on the telephone 900 connected to the HGW 901, similarly to the change of the white list.

  Notification of annoying suspicion calls to the user by the telephone function can be performed by the following method by changing the change rule of the telephone number and name information in the HGW 901. FIG. 12 is a diagram for explaining a notification method according to the third embodiment of the present invention.

  Case 1 is a case where the HGW 901 changes the telephone number (A01).

  Prefix is added to the head of the telephone number or changed to a fixed telephone number. The telephone number is displayed on the telephone and / or read out, and the user can recognize that the telephone number is a suspicious telephone call.

  Alternatively, when changing to a fixed telephone number, it is possible to display and read out with the registered name of the telephone book by registering the telephone number in advance in the telephone address book.

  Case 2 is a case where the HGW 901 changes name information (A01).

  Prefix is added to the name information or changed to a fixed name.

  The user can be notified of the changed name by at least one of the display function and the reading function of the telephone. Rather than changing the phone number, the user can easily determine that the phone is annoying.

  Case 3 is a case of changing to non notification (A03).

  The non-notification incoming call rejection function of the telephone makes it possible to perform an operation such that a call is not made when an incoming call is received.

  As described above, the third embodiment has an effect that annoying suspicious telephone call can be notified by at least one of number display display and reading out of the telephone.

  The reason is that the communication system according to the present embodiment changes the telephone number and name information of the suspicious telephone in the HGW 901.
