Description

  The present invention relates to a technique for performing communication with a communication partner by selecting the communication partner on a Web page displayed on a personal computer.

  Many technologies related to the Internet are in widespread use, and in particular, Web technologies as a means for information disclosure and information collection are widely used. Under such circumstances, as seen in the spread of social network services (SNS) and blogs, the use of the Web is not just a means of disclosure and collection of information, but easy communication between individuals (mainly anonymous). It has changed into a place. For example, in a social network service, information can be easily exchanged with an anonymous partner who is a friend or a member of a community.

  In relation to information exchange, Patent Document 1 discloses a two-way voice call between a user-side terminal and a website-side facility in a state in which information displayed on the website is displayed on the user-side terminal. Techniques for performing are disclosed. Further, Patent Document 2 discloses a technique related to call control by SIP.

  By using social network services and blogs as described above, users can easily communicate with others who are not acquainted directly, but the communication is mainly limited to character base.

  If the real-time communication by voice or video can be done with the same level of convenience as the communication by text on social network services and blogs, higher-density communication will be possible and the convenience of users will be improved.

There was no prior art to meet such needs. Although it is conceivable to use the technique disclosed in Patent Document 1 for such needs, the technique disclosed in Patent Document 1 requires that a telephone communication program be installed in the terminal in advance. In addition, telephone communication can be performed only with a predetermined call partner terminal (terminal on the website side facility), and it is not possible to easily make a call with an arbitrary member in a social network service or a blog.

This is a functional unit that notifies that effect.

<System operation>
Next, an operation example of the system having the above configuration will be described with reference to sequence charts shown in FIGS.

  First, based on an operation by the user, the information browsing unit 51 of the user A terminal 5 transmits a login request to the website providing apparatus 1 (step 21). The service providing unit 11 in the Web site providing apparatus 1 receives the login request, and transmits login screen data to the information browsing unit 51 of the user A terminal 5 (step 22). When the user inputs an ID and password (service authentication information A) for using the service provided by the website providing apparatus 1 according to the screen, the service authentication information A is received from the user A terminal 5 by the website providing apparatus. 1 (step 23), and the user authentication unit 14 of the website providing apparatus 1 performs user authentication. In this example, it is assumed that user authentication is successful (step 24).

  As a result, the user ID of the user A is recorded in the user information storage unit 15 as the user ID of the logged-in user in association with the community to which the user A belongs.

  Then, the other user information providing unit 12 in the website providing apparatus 1 acquires a list of user IDs of other users who are currently logged in from the user information storage unit 15 in the community to which the user A belongs, A is transmitted to the terminal 5 (step 25).

  Further, the other user information providing unit 12 monitors login / logout by other users in the community to which the user A belongs, and when there is login / logout, the changed information is sent to the user A terminal 5 in real time. Send to.

  The information browsing unit 51 of the user A terminal 5 receives the list of user IDs of other users and displays it on the display of the user A terminal 5. When the user A who sees the list of user IDs of other users displayed on the display selects (clicks) a partner (here, user B) who wants to make a call from the list, the information browsing unit 51 displays The telephone communication request including the service IDB (user ID of user B) and the URL of the Web site providing apparatus 1 is generated based on the link information corresponding to the user B, and the control information generation and transmission of the telephone communication program providing apparatus 2 is performed. It transmits to the part 21 (step 26).

  Upon receiving the telephone communication request, the control information generation / transmission unit 21 extracts the service IDB from the telephone communication request and refers to the correspondence table of the database device 7 to thereby determine the SIP-URI (for telephone communication) corresponding to the service IDB. Called ID (IDB for telephone communication here) is acquired, and control information including the telephone communication IDB, the storage location of the telephone communication program, and the URL of the Web site providing apparatus 1 is generated. Is transmitted to the information browsing unit 51 of the user A terminal 5 together with the type identification information (step 27).

  The information browsing unit 51 that has received the control information and the type identification information activates the control information interpretation execution unit 52 based on the type identification information and passes the control information to the control information interpretation execution unit 52 (step 28). The control information interpretation execution unit 52 checks whether or not the telephone communication program is downloaded to the user A terminal 5 based on the information included in the control information, and if not downloaded, the telephone communication program included in the control information.

This registration / authentication request includes the telephone communication IDA and password (referred to as a telephone communication password, here the telephone communication password A) of the user A terminal 5. In the first embodiment, the telephone communication ID and the telephone communication password of the user who makes a call first (the telephone communication ID and the telephone communication password are collectively referred to as authentication information for telephone communication). May read and transmit what is stored in the storage device of the user A terminal 5 in advance, or display an input screen on the user A terminal 5 so that the user A can use the telephone communication ID and the telephone communication. It is also possible to enter a password. This registration / authentication request is realized, for example, as a SIP REGISTER message.

  The call control processing unit 31 of the call control device 3 performs an authentication process and a registration process using the telephone communication IDA and the telephone communication password A. In the registration processing in the call control device 3, processing for storing the terminal identification address (IP address) of the user A terminal 5 and the telephone communication ID in association with each other in the storage device is performed.

  Thereafter, the telephone communication function unit 53 transmits to the call control device 3 a call connection request (INVITE message) that uses the telephone communication IDB of the other party as the call connection request destination (step 33). . This call connection request includes the telephone communication IDA and the URL of the Web site providing apparatus 1.

  Here, if the registration processing for the call control device 3 has been completed on the user B side as the call partner, the call connection request is transferred to the user B terminal 6, and the call starts via a normal SIP call connection sequence. However, it is assumed here that the user B has not performed registration processing for the call control device 3.

  In the case of normal processing based on SIP, the call control processing unit 31 of the call control device 3 that has detected that the telephone communication IDB is not stored in the storage device receives a message (Not Found) indicating that the target is unknown. However, in this embodiment, the call control processing unit 31 returns a trying message (trying) to the telephone communication function unit 53, and the processing is continued to the telephone communication function unit 53. Is notified (step 34). Then, the call control processing unit 31 waits for the user B to be registered.

  In step 34, the call control processing unit 31 sends a message indicating that “user B is called but it is likely that it will take some time for user B to answer the call” together with the in-trial message and the telephone communication function unit. 53, and the telephone communication function unit 53 may output the message on the screen or as a voice.

  The call connection request information notifying unit 32 in the call control device 3 includes the telephone communication IDA and the telephone communication IDB by using the URL of the website providing device 1 included in the call connection request. Notification information indicating that there is a call connection request from user A to user B is transmitted to Web site providing apparatus 1 (step 35).

Get IDA for service and IDB for service. In addition, by referring to the user information storage unit 15, it is checked whether or not the user B is logged into the website providing apparatus 1. Here, it is assumed that the user has logged in.

  Then, the other user information providing unit 12 in the website providing apparatus 1 browses the information on the user B terminal 6 for the notification information indicating that the user A has made a call connection request to the user B, including the service IDA of the user A. It transmits to the part 61 (step 36). This notification information includes, for example, a message “A phone is coming from Mr. A. Click to answer.” Also, an OK button as display information and link information as non-display information are included.

  The other user information providing unit 12 transmits information indicating whether or not the user B is logged in to the call control device 3 (step 37). The call control device 3 that has received the information sets a timer for waiting for registration from the user B.

  If the user B is not logged in at the time of step 35, for example, the other user information providing unit 12 notifies the call control device 3 of a message that the user B has logged out without executing step 36. Upon receiving the notification, the call control device 3 transmits a Not Found message to the user A terminal 5. In the present embodiment, it is assumed that user B continues to log in.

  The information browsing unit 61 of the user B terminal 6 that has received the notification information in step 36 displays an OK button together with the above message. The link information corresponding to the display information of the OK button is basically the same as the link information used in step 26, and includes information for connecting to the control information generation / transmission unit 21.

  When the user B clicks the OK button, the information browsing unit 61 transmits a telephone communication request to the control information generation / transmission unit 21 of the telephone communication program providing apparatus 2 based on the link information (step 38). Note that the information browsing unit 61 may automatically transmit a telephone communication request to the telephone communication program providing apparatus 2 without the user B clicking the OK button.

  Upon receiving the telephone communication request, the control information generation / transmission unit 21 generates control information including the storage location of the telephone communication program, and transmits the control information to the information browsing unit 61 of the user B terminal 6 together with the type identification information. (Step 39).

  The information browsing unit 61 that has received the control information and the type identification information activates the control information interpretation execution unit 62 based on the type identification information and passes the control information to the control information interpretation execution unit 62 (step 40). The control information interpretation execution unit 62 checks whether or not the telephone communication program is downloaded to the user B terminal 6 based on the information included in the control information, and if not downloaded, the telephone communication program included in the control information. The telephone communication program download request is transmitted to the download unit 22 in the telephone communication program providing apparatus 2 based on the storage location information (step 41).

  Upon receiving the telephone communication program download request, the download unit 22 downloads the telephone communication program to the user B terminal 6 in response to the request (step 42). The downloaded telephone communication program is stored in the storage device of the user B terminal 6. Then, the control information interpretation execution unit 62 activates the downloaded telephone communication program to generate the telephone communication function unit 63 (step 43).

  Thereafter, the telephone communication function unit 63 sends a registration / authentication request to the call control device 3 (step 44). This registration / authentication request includes user B's telephone communication IDB and telephone communication password B of user B terminal 6. The method for obtaining the authentication information B for telephone communication in the present embodiment is the same as that for the user A.

  In the call control device 3, authentication processing and registration processing are performed by the telephone communication IDB and the telephone communication password B.

  Since the call control device 3 is continuing the processing of the call connection request for the user B terminal 6 received from the user A terminal 5 and has been waiting for the user B's telephone communication IDB to be registered, as described above. When the registration process is performed, the call connection request process proceeds.

  In step 45, the call control device 3 transmits a call connection request for the user B terminal 6 to the telephone communication function unit 63 of the user B terminal 6. As a result, the user B terminal 6 is notified of incoming calls (such as ringing a bell), and the user B responds to start a call (steps 46 to 49).

  In the example described above, the call control device 3 notifies the Web site providing device 1 using the URL of the Web site providing device 1 included in the call connection request. However, the method of determining the notification destination Web site providing apparatus corresponding to the other party (user B in the above example) is not limited to the above example.

  For example, the database device 7 stores the telephone communication ID and the URL of the Web site providing device in association with each other, and the call connection request information notification unit 32 of the call control device 3 uses the telephone communication request destination for the telephone communication request. The URL of the Web site providing apparatus corresponding to the ID may be acquired from the database apparatus 7 and information notification may be performed using the URL. When the telephone communication ID is in the telephone number format, the database device 7 stores the telephone number band and the URL of the Web site providing device in association with each other as shown in FIG. 3 obtains the URL of the Web site providing apparatus corresponding to the number band to which the telephone communication ID that is the destination of the call connection request belongs from the database apparatus 7, and uses the URL to notify information. It is good also as performing. The correspondence information between the telephone communication ID and the URL of the website providing apparatus, and the correspondence information between the number band and the URL of the website providing apparatus may be stored in a storage device in the call control device 3.

  In the above example, in step 34, the call control device 3 notifies the user A terminal 5 of “Trying”. Instead of this processing, the call control device 3 sends a “Not Found” message. Then, the call control process related to the user A terminal 5 may be stopped, and the user B may make a call. In that case, differences from the above example will be mainly described with reference to FIG.

  In this case, the link information corresponding to the display information of the OK button notified to the user B terminal 6 in step 36 includes the service IDA of the user A together with the information for connecting to the control information generating / transmitting unit 21.

  When the user B clicks the OK button, the information browsing unit 61 transmits a telephone communication request including the service IDA of the user A to the control information generation / transmission unit 21 of the telephone communication program providing apparatus 2 based on the link information. (Step 38). The control information generation / transmission unit 21 that has received the telephone communication request refers to the correspondence table of the database device 7, acquires the telephone communication IDA corresponding to the service IDA, and determines the telephone communication IDA and the telephone communication program. Control information including the storage location is generated, and the control information is transmitted to the information browsing unit 61 of the user B terminal 6 together with the type identification information (step 39).

  The information browsing unit 61 that has received the control information and the type identification information activates the control information interpretation execution unit 62 based on the type identification information and passes the control information to the control information interpretation execution unit 62 (step 40). The control information interpretation execution unit 62 checks whether or not the telephone communication program is downloaded to the user B terminal 6 based on the information included in the control information, and if not downloaded, the telephone communication program included in the control information. The telephone communication program download request is transmitted to the download unit 22 in the telephone communication program providing apparatus 2 based on the storage location information (step 41).

  Upon receiving the telephone communication program download request, the download unit 22 downloads the telephone communication program to the user B terminal 6 in response to the request (step 42). Then, the control information interpretation execution unit 62 activates the downloaded telephone communication program, generates the telephone communication function unit 63, and passes the telephone communication IDA to the telephone communication function unit 63 (step 43).

  Thereafter, the telephone communication function unit 63 performs registration / authentication processing for the call control device 3. Thereafter, the sequence is different from the above example, and the telephone communication function unit 63 of the user B terminal 6 transmits a call connection request addressed to the telephone communication IDA to the call control device 3 and undergoes processing based on SIP. A call is made with user A.

  FIG. 12 is a diagram illustrating an example of processing when no click is made on the user B side. As shown in FIG. 12, the above-described steps 34 to 37 are performed, but the telephone communication program download processing on the user B side is not performed, and when the timer in the call control device 3 expires (for example, a timer is set). 180 seconds after that, a Not Found message is returned to the user A terminal 5 (step 50).

(Second Embodiment)
In the first embodiment, other users who are logged in to the Web site are displayed on the Web screen, and by simply clicking on the other party, the other party can be easily accessed without manually entering the other party's information.

  FIG. 13 shows an example of the correspondence table in the present embodiment. As shown in FIG. 13, the correspondence table includes, for each user, service authentication information (service ID and service password) and telephone communication authentication information (telephone communication ID and telephone communication password). Including.

When a cookie is used for transmission / reception of telephone communication authentication information, the user authentication unit 14 according to the present embodiment uses the service authentication information (service ID and service password) as cookie information when the user authentication is successful. It has a function to return to the terminal. Also, a method not using a cookie can be adopted, and in this case, the other user information providing unit 12 has a function of embedding and transmitting service authentication information in the Web link information included in the list of other user IDs.
In the case of a method using cookies, in order to prevent information leakage, the user authentication unit 14 that issues cookies and the control information generation and transmission unit 21 that uses cookies are placed in the same domain, Limit the scope to that domain. In this case, the user authentication unit 14 and the control information generation / transmission unit 21 may be installed in the same domain as other functional units of the website providing apparatus 1 or installed in another domain. You may make it communicate with a function part by transfer by redirection etc.

  The information browsing unit 51 of the user A terminal 5 that has received the cookie information or the authentication information embedded in the link, when a call partner is selected (clicked), the service ID corresponding to the user ID, A telephone communication request including the service authentication information A as additional information is transmitted to the control information generation / transmission unit 21 of the telephone communication program providing apparatus 2.

  Furthermore, when the service providing unit 11 according to the present embodiment receives a logout request from the information browsing unit 51 of the user A terminal 5, the service providing unit 11 transmits a request for deleting the additional information, and generates and transmits control information to the user A terminal 5. It has a function of transmitting a redirect request for requesting access to the unit 21. The same applies to the user B terminal 6.

  In addition, the control information generation / transmission unit 21 of the telephone communication program providing apparatus 2 according to the present embodiment receives a telephone communication request transmitted from the user terminal, and from the telephone communication request, the service authentication information and the communication partner service By extracting the ID and referring to the correspondence table of the database device 7, the telephone communication authentication information corresponding to the service authentication information and the telephone communication ID corresponding to the service ID of the other party are obtained. It has the function to generate | occur | produce the control information containing this information, and to transmit to a user terminal.

  The control information generation / transmission unit 21 also has a function of generating control information corresponding to logout and transmitting it to the user terminal when a logout request is received from the user terminal.

  Hereinafter, the operation of the system according to the present embodiment will be described with reference to the sequence charts shown in FIG. 14, FIG. 15, and FIG.

  Similarly to the first embodiment, login from the user A (sending service authentication information A including the service IDA and the service password A) is performed, and the Web site providing apparatus 1 succeeds in user authentication. . When transmitting / receiving service authentication information using a cookie, the user authentication unit 14 of the website providing apparatus 1 uses the service authentication information A as cookie information to the user A terminal 5 as a login response. The information browsing unit 51 of the user A terminal 5 stores the service authentication information A in the storage device.

  Subsequently, similarly to the first embodiment, the other user information providing unit 12 in the Web site providing apparatus 1 transmits the user ID list of the logged-in other user to the information browsing unit 51 of the user A terminal 5. Then, it is displayed on the user A terminal 5 (step 65). When a method that does not use a cookie for transmission / reception of telephone communication authentication information is adopted, service authentication information A is included as Web link parameter information.

  Subsequently, when the user B is clicked on the display screen, the information browsing unit 51 includes the service IDB and the URL of the website providing apparatus 1 based on the link information corresponding to the displayed user B. The telephone communication request is transmitted to the control information generation / transmission unit 21 of the telephone communication program providing apparatus 2 (step 66). When transmitting / receiving service authentication information using a cookie, service authentication information A is added as cookie information to the telephone communication request. Also, when adopting a scheme that does not use cookies, the service authentication information A, which is Web link parameter information, is read from the storage device, and the service authentication information A is added to the telephone communication request and transmitted.

  Upon receiving the telephone communication request, the control information generation / transmission unit 21 extracts the service authentication information A of the user A and the service IDB of the user B of the other party from the telephone communication request, and the telephone corresponding to the service authentication information A The communication authentication information A is acquired from the database device 7 and the telephone communication IDB corresponding to the service IDB of the other party is acquired from the database device 7.
