Description

  The present invention is a system that enables call connection between the user and the other party by depressing the call button displayed on the web page. The present invention relates to a technique for preventing fraud that increases the load on the server side by pushing.

  It is now common for companies to place advertisements including telephone numbers on websites and receive inquiries. There are roughly the following three types of mechanisms for a user who accesses such a website from a user terminal to make a telephone contact with a company that is an advertiser on the web page.

  The first method is a method in which a user views a telephone number displayed on a web page and makes a call by inputting the telephone number by himself / herself into a telephone terminal.

  The second method is based on the premise that a softphone is installed in the user terminal and the telephone number displayed on the Web page is linked to the automatic call function. In the second method, when the user clicks a telephone number displayed on the Web page, the user terminal automatically makes a call to the telephone number by the function of the softphone.

  The third method is to press the call button displayed on the Web page and the call control system calls the user side telephone terminal and the company side telephone terminal by the callback method to detect the off-hook of both. This is a method of connecting the two. The outline of the process of the third method will be described with reference to FIG.

  In FIG. 1, the user side is provided with a user terminal 1 that accesses a Web site via the Internet and a telephone terminal 3 that can make a call via the telephone network, and the company side via the telephone network. It is assumed that a telephone terminal 5 capable of making a call is provided. The web server 7 in FIG. 1 constitutes a corporate website and has a function of providing an advertisement web page. Further, the call control system 9 has a function of receiving a call instruction and making a call to the user's telephone terminal 3 and the company's telephone terminal 5 and connecting the two.

  In FIG. 1, the user accesses the web server 7 to display a web page on the user terminal 1 (steps 1 and 2), and clicks a call button (button for making a call) displayed on the user terminal 1. If this is the first call, enter your phone number and click the button. This telephone number is stored in the user terminal 1 as a cookie, and a call can be made without inputting the telephone number from the next call.

  A call instruction including a telephone number is transmitted to the call control system 9 by clicking (step 3). The call control system 9 calls the user's telephone terminal 3 using the telephone number included in the outgoing call instruction (step 4) and calls the company's telephone terminal 5 using the preset company's telephone number (step 4). 5) Call connection between the two (step 6).

In addition, there exists patent document 1 as a prior art document relevant to this application, for example.
JP-A-2005-244421

  The first method in the background art described above has the advantage that there is no restriction on the type of telephone terminal used by the user, but the disadvantage is that an operation for inputting the telephone number displayed on the Web page by itself is required. There is. Further, the second method has a drawback that only a soft phone can be used.

  On the other hand, the third method has an operational advantage that there is no restriction on the type of telephone terminal used by the user and that the user can basically make a call connection by simply clicking a button. Further, since the call control system 9 makes a call to each of the user and the company, there is an advantage that the user's telephone number is not transmitted to the company side. In this way, it is considered that the number of users and traffic will increase in the third method in which a user can easily make a call from a Web page using an existing telephone terminal.

  By the way, in the third method, it is conceivable that a mischievous phone call is performed in which a third party's telephone number which is not his / her own telephone number is input and a third party is received by clicking a call button. For third parties, there is a countermeasure for registering the incoming call from such an undesired partner with the network side so as to reject the call from the caller corresponding to the incoming call.

  However, even if the above-mentioned countermeasure is taken on the side of the mischievous caller, the outgoing operation cannot be stopped, and fraud such as intentionally increasing the load on the call control system 9 side by repeating the outgoing operation is performed. Therefore, measures to prevent such fraud are required.

  The present invention has been made in view of the above points, and in a system that enables call connection between the user and the other party by depressing the call button displayed on the web page, the user performs an unauthorized call operation. It is an object of the present invention to provide a technique for preventing repetition.

  The above problem is that a call is made to each of the first telephone terminal and the second telephone terminal in response to a telephone call request from the user terminal, and between the first telephone terminal and the second telephone terminal.

  Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment]
(System configuration)
FIG. 2 shows an example of a system configuration in the first embodiment of the present invention. As shown in FIG. 2, this system includes a user terminal 11 for a user who makes a call to a company, a user telephone terminal 13, a web server 15 for providing a company website, and call control for performing call connection control between telephone terminals The system 17 and a company telephone terminal 19 for making a call connection with the user telephone terminal 13 in the company are provided.

  The user terminal 11, the Web server 15, and the call control system 17 are connected to the Internet 23, and the user telephone terminal 13 and the enterprise telephone terminal 19 are connected to the telephone network 25. The Internet 23 and the telephone network 25 include a VoIP network. The user terminal 11 and the user telephone terminal 13 are not necessarily separate terminals, and may be the same terminal. The call control system 17 includes a call connection request processing device that performs call connection permission / rejection determination processing and the like, and a call control device that performs call control based on SIP such as calling a telephone terminal. Is mainly executed by the call connection request processing device. Note that the network to which the user terminal 11, the Web server 15, and the call control system 17 are connected is not limited to the Internet.

  The user terminal 11 is a general computer such as a PC (personal computer), and is installed with a browser which is software for realizing a Web browsing function.

  In addition, it is a general technique to perform call connection control such as callback by SIP (Session Initiation Protocol) in a VoIP (Voice over IP) network. In this embodiment, the call control apparatus in the call control system 17 is SIP. The call control based on the present invention is performed, but the method for performing the call control in the present invention is not limited to SIP.

  Although the present embodiment is intended for call connection between a company and a general end user as a customer, the present invention is not limited to this example. For example, the system of the present invention can be used when another end user makes a call to an end user who has a Web page, or for telephone contact within a company or between companies.

(About processing overview)
An overview of the processing in the present embodiment will be described with reference to the sequence chart of FIG. Communication in each sequence described below is performed by http or https, but the communication protocol is not limited to these.

  When the user performs an operation for browsing the company's Web page on the user terminal 11, the user terminal 11 accesses the Web site provided by the Web server 15, and the Web page is displayed on the user terminal 11 ( Steps 13 and 14). The user depresses (clicks) a predetermined inquiry button displayed on the Web page. The inquiry button is embedded with an identifier of the website (referred to as website identification information) provided by the web server 15, and when the inquiry button is pressed, a call connection request including the website identification information is received from the user terminal 11. Is transmitted to the call control system 17 (step 15). The Web server 15 may provide a Web page that displays a plurality of Web sites (for example, Web sites of a plurality of companies). In that case, the Web page 15 includes a plurality of inquiries corresponding to the plurality of Web sites. A button is displayed, and the Web site identification information corresponds to the Web site corresponding to the inquiry button selected by the user.

  Thereafter, the call control system 17 acquires information on the number of times of use corresponding to the website identification information included in the cookie transmitted from the user terminal 11 to the call control system 17, and the number of times of use and a preset limit number of times are obtained. To determine whether or not to permit the call connection request by the user terminal 11 (step 16). Then, the call control system 17 transmits screen data corresponding to the determination result of whether or not to permit the call connection to the user terminal 11 (step 17).

  When permitting a call connection request, a telephone call request screen shown in FIG. 4 is displayed. The user inputs the telephone number of the user telephone terminal 13 on this screen and depresses the call button. Thereby, a telephone call request including the telephone number information of the user telephone terminal 13 is transmitted from the user terminal 11 to the call control system 17 (step 18).

  Based on this telephone call request, the call control system 17 makes a telephone call to the user telephone terminal 13 (step 19) and makes a telephone call to the corporate telephone terminal 19 corresponding to the Web site selected by the user. (Step 20). Then, off-hook of both telephone terminals is detected, and both telephone terminals are connected. Thereafter, a telephone call is made between the telephone terminals (step 21).

  If “save phone number” was previously selected on the telephone call request screen shown in FIG. 4, the phone number is stored in the user terminal 11 as a cookie, and the call control system 17 calls the phone number. Is acquired, a telephone number is acquired from the cookie, and data of a telephone call request screen in which the telephone number is embedded is transmitted in step 17. Therefore, in this case, the user can transmit a telephone call request without entering a telephone number.

  In step 16, when the call control system 17 determines that the call connection by the user terminal 11 is not permitted, the screen shown in FIG. 5 is displayed on the user terminal 11. As shown in FIG. 5, in this case, the user cannot make a telephone call. That is, the call is rejected. The “declaration ID” displayed here is a cookie ID for identifying the user terminal 11. Details of how to use the cookie ID will be described later.

(Judgment processing in the call control system 17)
Next, the processing in the call control system 17 will be described in more detail with reference to FIGS. 6 to 10, focusing on the processing relating to call connection permission / rejection determination in the call control system 17. In the following description, each piece of information included in the cookie can be encrypted as appropriate in the call control system 17, and when using the information encrypted in the call control system 17, it is decrypted and used as appropriate.

  When the inquiry button displayed on the web page is pushed down on the user terminal 11, a call connection request including web site identification information is transmitted to the call control system 17 (step 30 in FIG. 6). The call control system 17 that has received the call connection request transmits to the user terminal 11 a request for acquiring cookie information corresponding to the telephone number from the cookie information stored in the user terminal 11 (step 31). That is, the call control system 17 transmits a command for causing the user terminal 11 to transmit a cookie including a telephone number.

  In FIG. 7, an example of the content of the cookie which the user terminal 11 accumulate | stores is shown. The example of FIG. 7 includes information obtained by encrypting the telephone number previously input by the user, and information on the number of uses, cookie ID, and expiration date associated with the Web site identification information. The cookie ID is information for identifying the browser of the user terminal 11 and is information that the call control system 17 pays out. Since the user terminal 11 can be identified by the cookie ID, this can also be called identification information of the user terminal 11.

  In FIG. 6, the call control system 17 receives the information in response to the request in step 31 (step 32), and if the received information includes a telephone number cookie (Yes in step 33), the telephone number Is embedded in the data of the telephone call request screen shown in FIG. 4 (step 34). If the telephone number is not included, the telephone number input field on the telephone call request screen is left blank.

  Subsequently, the call control system 17 sends a request for acquiring a cookie including the number of uses and the cookie ID corresponding to the Web site identification information received in step 30 from the cookie information stored in the user terminal 11. 11 (step 35).

  The call control system 17 receives the information in response to the request in step 35 (step 36), and determines whether or not the received information contains a cookie indicating the number of uses (step 37). If the number of times of use is not included, the number of times of use is set to 1 (step 38), and a cookie including Web site identification information, cookie ID, and number of times of use is transmitted to the user terminal 11 (step 39). Save.

  Note that all the cookies used in step 33 and step 37 may be included in the request received in step 30. In this case, in steps 33 and 37, necessary information is acquired from the cookie received in step 30.

  In step 37, the fact that the usage count cookie is not included in the received information means that the inquiry use at the website corresponding to the website identification information received in step 30 is the first time, or the usage count cookie is the user. It means that the terminal 11 has been deleted due to expiration. In any case, if the received information does not include the usage count cookie, the user does not frequently make inquiries on the Web site, and the call control system 17 receives the call from the user terminal 11. The call connection request is permitted, and the data on the telephone connection request screen shown in FIG. 4 is transmitted to the user terminal 11 (step 40). As described above, if the telephone number is included in step 33, this screen data includes the telephone number.

  If there is a use count cookie in step 37, as shown in FIG. 8, the call control system 17 determines whether the use count exceeds a preset limit count (step 50). The limit count is stored in advance in the call control system 17 in association with the Web site identification information.

  If it is determined in step 50 that the usage count does not exceed the predetermined limit count, the call control system 17 determines whether the usage count matches the limit count (step 51). If they do not match, the call control system 17 adds 1 to the number of times of use (step 52), and transmits a cookie including the website identification information, cookie ID, and number of times of use to the user terminal 11 (step 53). Saves the cookie. If the number of uses does not match the limit number in step 51, the number of uses is less than the limit number. Therefore, the call control system 17 accepts the call connection request from the user terminal 11, and the data on the telephone call request screen in FIG. It transmits to the user terminal 11 (step 54), and the user terminal 11 displays the screen.

  If it is determined in step 51 that the number of uses matches the limit number, the number of uses has reached the limit number. In this case, the call control system 17 stores the cookie ID acquired in step 36 in association with the corresponding website identification information in the restriction table described later (step 55), and adds 1 to the number of uses (step 56). Then, a cookie including Web site identification information, cookie ID, and usage count is transmitted to the user terminal 11 (step 57), and the user terminal 11 stores the cookie. Then, in order to reject the call connection request from the user terminal 11, the call control system 17 transmits the data of the call connection rejection screen shown in FIG. 5 to the user terminal 11 (step 58), and the user terminal 11 displays the screen. indicate.

  FIG. 9A shows an example of a restriction table. As shown in FIG. 9A, the restriction table stores Web site identification information and cookie IDs. In the example of FIG. 9A, for example, the user terminal (browser) corresponding to the cookie ID = 321 has transmitted the inquiry more than the limit number to the Web site corresponding to the Web site identification information = 123. Show.

  The call control system 17 deletes the information stored in the restriction table at a predetermined time (for example, every morning at 8:00). In addition, as shown in FIG. 9B, when the registration time (the time when the cookie ID is registered in the restriction table) is recorded for each cookie ID in the restriction table, and a predetermined time has elapsed from the registration time. The record corresponding to the corresponding cookie ID may be deleted. It is also possible to delete the information in the restriction table by an operation by the operator.

  If it is determined in step 50 of FIG. 8 that the number of uses exceeds the limit number, the call control system 17 stores the corresponding cookie ID in association with the corresponding website identification information in the limit table. It is determined whether or not (step 60 in FIG. 10). As described above, the cookie ID is deleted from the restriction table when a predetermined time elapses, but if this is stored, the number of times the limit is exceeded within the predetermined time, the website ID corresponding to the website identification information is deleted. Since there is an inquiry request (call connection request), the call control system 17 determines that this is illegal, and transmits the data of the call connection rejection screen to the user terminal 11 (step 61).

  In step 60, when it is determined that the corresponding cookie ID is not stored in association with the corresponding website identification information in the restriction table, a predetermined time has elapsed since the cookie ID was stored, and then the number of restrictions is set. This means that there has been no use of inquiries on the surplus websites, so the call control system 17 determines that the use by the user is not illegal, sets the number of uses to 1 (step 62), the web site identification information, A cookie including the cookie ID and the number of uses is transmitted to the user terminal 11 (step 63). In addition, the telephone call request screen data is transmitted to the user terminal 11 (step 64), and the screen is displayed on the user terminal 11. In the above processing, when the number of uses exceeds the limit number, the number of uses is not increased, but this may be increased.

  If the call connection request is simply rejected when the usage count exceeds the limit, the call connection request is rejected even if the inquiry is made many times over a long period of time. The case where it is done will occur. Therefore, such inconvenience can be prevented by performing control using the restriction table as described above.

  In addition, if the user makes a valid inquiry operation and reports that the call connection request has been rejected, the cookie ID corresponding to the declaration ID (= cookie ID) is deleted from the restriction table. By doing so, the user can make an inquiry without being denied a call connection request.

(Device configuration)
Next, a device configuration example of the call control system 17 will be described. As shown in FIG. 11, the call control system includes a call connection request processing device 100 that performs call connection permission / rejection determination processing and the like, and a call control device 200 that performs call control based on SIP such as calling a telephone terminal. The call connection request processing device 100 and the call control device 200 may be connected via a network such as the Internet, or may be directly connected. FIG. 12 shows a functional configuration diagram of the call connection request processing apparatus 100.

  As shown in FIG. 12, the call connection request processing apparatus 100 includes a data transmission / reception unit 101, a request processing unit 103, a cookie information acquisition unit 105, a call connection permission / rejection determination unit 107, a screen creation / transmission unit 109, and a call connection process. An instruction unit 110, a data storage unit 112, and a data management unit 114 are provided.

  The data transmission / reception unit 101 is a functional unit for transmitting / receiving data to / from other devices. The request processing unit 103 determines the request from the user terminal 11 received by the data transmitting / receiving unit 101 (call connection request transmitted by pressing the inquiry button, telephone call request transmitted by pressing the call button), and the request It is a function part for starting the process according to. The cookie acquisition unit 105 is a functional unit for acquiring cookie information necessary for processing after receiving a call connection request transmitted by pressing the inquiry button.

  The call connection permission / rejection determination unit 107 is a functional unit that performs call connection permission / rejection determination based on the usage count and restriction table. The screen creation / transmission unit 109 is a functional unit that creates screen data corresponding to the determination result by the call connection permission / rejection determination unit 107 and transmits the screen data to the user terminal 11. The call connection processing instruction unit 110 is a functional unit that instructs the call control device 200 to perform a process for performing a call connection between the user telephone terminal 13 and the enterprise telephone terminal 19 when the call connection is permitted. The data storage unit 112 holds setting data set in advance such as the number of times of restriction and the telephone number of the company, and also holds a restriction table. Further, as described above, the data management unit 112 has a function of deleting data in the restriction table based on time. The data management unit 112 also has a function of transmitting a restriction table operation screen to an administrator terminal (not shown) and deleting the data in the restriction table based on an operation from the administrator terminal.

  The call connection processing device 100 is realized by mounting a program for executing the processing described in this embodiment on a general computer including a CPU, a storage unit such as a memory, and a communication device. Can do. The program can be recorded on a recording medium such as a CD-ROM or a memory, distributed, and installed on a computer. Further, the functional classification of the call connection processing device 100 is not limited to that shown in FIG. Any functional classification may be used as long as the processing described in the present embodiment can be realized. Furthermore, the call connection processing device 100 and the call control device 200 can be configured as one device.

[Second Embodiment]
In the methods described so far, call connection permission / rejection determination is performed using a cookie, but call connection permission / rejection determination can also be performed without using a cookie.

  For example, when a mobile phone terminal is used as the user terminal 11, individual identification information of the mobile phone terminal can be used. The individual identification information is a value unique to the mobile phone terminal. In the second embodiment, a case where a mobile phone terminal is used as the user terminal 11 and individual identification information is used for call connection permission / rejection determination will be described. The system configuration in this embodiment is the same as that in the first embodiment, and is different from the first embodiment in that call connection permission / rejection determination is performed using individual identification information instead of cookies. Processing in the present embodiment will be described with reference to FIGS.

  In the present embodiment, the call control system 17 holds Web site identification information, a telephone number, and the number of uses in association with individual identification information. Also, it is assumed that the individual identification information and the website identification information are stored in the restriction table in association with each other.

  When the inquiry button is depressed on the user terminal 11, a call connection request including Web site identification information is transmitted to the call control system 17 (step 70 in FIG. 13). In the second embodiment, individual identification information is included in this call connection request. In addition, after the request | requirement of step 70, it is also possible for the call control system 17 to request | require the user terminal 11 to transmit individual identification information, and to acquire individual identification information by it. In addition, a dialog for confirming transmission of the individual identification information may be displayed to the user on the user terminal 11, and the individual identification information may be transmitted only when permitted by the user.

  Next, the call control system 17 determines whether or not the telephone number associated with the individual identification information and the website identification information is held in the storage means (step 71). The telephone number is embedded in the telephone call request screen data shown in FIG. 4 (step 72). If no telephone number is held, the telephone number input field on the telephone call request screen is left blank.

  Subsequently, the call control system 17 determines whether or not the number of uses corresponding to the individual identification information and the website identification information received in Step 70 is held in the storage means (Step 73). If the number of times of use is not held, the number of times of use is set to 1 (step 74), and the information is stored in association with the individual identification information and the website identification information (step 75). Then, the call control system 17 allows the call connection from the user terminal 11 and transmits the data of the telephone call request screen shown in FIG. 4 to the user terminal 11 (step 76). As described above, if the telephone number is held, the screen data includes the telephone number. Thereafter, after a call operation is performed, the telephone number is stored in association with the individual identification information.

  In step 73, when the number of uses corresponding to the website identification information and the individual identification information is held, the call control system 17 determines whether or not the number of uses exceeds a predetermined limit number (FIG. 14). Step 80).

  If it is determined in step 80 that the usage count does not exceed the predetermined limit count, the call control system 17 determines whether the usage count matches the limit count (step 81). If they do not match, the call control system 17 adds 1 to the usage count (step 82), and stores the usage count in the storage means in association with the individual identification information and the website identification information (step 83). Then, the call control system 17 transmits the data of the telephone call request screen of FIG. 4 to the user terminal 11 (step 84), and the user terminal 11 displays the screen.

  If it is determined in step 81 that the number of times of use matches the number of times of restriction, the individual identification information and the corresponding website identification information are stored in the restriction table (step 85), and 1 is added to the number of times of use (step 86). The number of uses is stored in association with the information identifier and the website identification information (step 87). Then, in order to reject the call connection request from the user terminal 11, the call control system 17 transmits the data of the call connection rejection screen shown in FIG. 5 to the user terminal 11 (step 88), and the user terminal 11 displays the screen. indicate.

  Similar to the first embodiment, the call control system 17 deletes the information stored in the restriction table at a predetermined time (for example, every morning at 8:00). In addition, the registration time (time when the individual identification information is registered in the restriction table) is recorded for each individual identification information in the restriction table, and when a predetermined time has elapsed from the registration time, the corresponding individual identification information is handled. The record may be deleted. It is also possible to delete the information in the restriction table by an operation by the operator.

  If it is determined in step 80 that the number of uses exceeds the limit number, the call control system 17 determines whether the corresponding individual identification information is stored in the limit table (step 90 in FIG. 15). . If stored, the call connection rejection screen data is transmitted to the user terminal 11 (step 91).

  If the individual identification information is not stored, the number of uses is set to 1 (step 92), and the number of uses is stored in association with the individual identification information and the website identification information (step 93). In addition, the telephone call request screen data is transmitted to the user terminal 11, and the screen is displayed on the user terminal 11 (step 94).

  Similar to the first embodiment, the call control system 17 also includes the call connection request processing device 100 and the call control device 200 in this embodiment. Further, the configuration of the call connection request processing apparatus 100 is as shown in FIG. 16, and is different from the configuration of FIG. 12 in that the cookie acquisition unit 105 is changed to the individual identification information acquisition unit 115. The individual identification information acquisition unit 115 acquires individual identification information from the request information received from the user terminal 11. In addition, the call connection permission / rejection determination unit 107 according to the present embodiment acquires the number of times of use associated with the individual identification information, not the information included in the cookie, from the data storage unit 112, and performs determination processing and the like. .

  The method described in the first embodiment is based on the assumption that the user terminal 11 supports the cookie function. Therefore, it cannot be applied when the user terminal 11 does not support the cookie function. On the other hand, in the present embodiment, even if the cookie function is not supported, the call connection permission / rejection determination process can be realized if the individual identification information is supported.

  Further, any information other than the individual identification information can be used as long as the information can identify the user terminal 11. For example, when an IP address is fixedly assigned to the user terminal 11, the IP address can be used. If it is an IP address, it can be acquired from the header of the IP packet transmitted from the user terminal 11.

  In the case of a member-based website, a membership number is input when the website is used, but the membership number can also be used as information for identifying the user terminal 11. In this case, for example, the member number may be embedded in the inquiry button on the web page, and the member number may be transmitted by the call control system 17 when the inquiry button is clicked.

  In these cases, the processing content of the call connection permission / rejection determination is the same as that obtained by replacing the individual identification information with an IP address or a member number.

(Effect of embodiment)
According to the call control system 17 described in each of the above embodiments, the usage count of the inquiry button (call connection request function) on the website is recorded as a cookie, or the usage count is recorded together with information for identifying the user terminal 11. Since the restriction is made so that the inquiry function cannot be used when the number of uses exceeds a predetermined number of times within a certain period of time, illegal mass telephone calls (especially calls aimed at unspecified majority) Can be prevented.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made within the scope of the claims.
