  The media server 34 is a media server that transmits a media such as a voice that notifies the first communication device 12 that the second communication device 13 is calling, but does not have the media server. It may be a configuration.

  The gateway 35 is a gateway for connecting different networks to each other, and may be connected to the plurality of interconnection points 22 from the gateway 35, or may be connected to a plurality of subscriber networks or the like without using the interconnection points 22. In addition, a plurality of subscriber networks of other companies may exist for the interconnection point 22.

  In the present system example, FIG. 1 describes the case where the calling and called communication devices are selected as mobile phones and general phones, but as described above, the SIP server 33 is used as the calling and called communication devices. When using an IP communication device accommodated in the mobile phone, it is not necessary to go through the gateway 35 or the interconnection point 22, and is appropriate when using a mobile phone, a general phone, or the like as a communication device as shown in the figure. It may be connected to an IP communication device.

  Next, Examples 1 to 5 applied to the call connection control system α configured as described above will be described in detail with reference to FIGS.

(Example 1)
First, in the embodiment in which a call request is made from the terminal device 11 to establish a call, the first communication device 12 and the second communication device 13 do not go from the SIP server 33 via the gateway 35 or the interconnection point 22. An example of a connected IP communication device will be described with reference to FIG.

  FIG. 2 is a flowchart from when a call request is transmitted from the terminal device 11 in the first embodiment to when the first communication device 12 and the second communication device 13 start a call via each server. .

  First, when a contractor inputs a user ID and a personal identification number to the WWW server 31 from the terminal device 11 and performs a login operation, the WWW server 31 authenticates the user ID and personal identification number of the contractor, and the user If the ID and password are valid, a call request screen is displayed on the screen of the terminal device 11 (S101).

  At this time, the application that runs on the terminal device 11 is made to automatically authenticate the user ID and the personal identification number in the same manner as the activation of the application, or the success fee charged according to the number of incoming calls. In the case of application to PayPerCall, which is currently spreading as a type advertisement, it is effective to authenticate each time a call request is made.

  From the call request screen displayed on the terminal device 11, the address of the first communication device 12, the address of the second communication device 13, and the address to the second communication device 13 (ID of the first communication device 12) Specified notification / non-notification, the address to be notified to the second communication device 13 (ID of the first communication device 12), and the contractor clicking the call button such as an object on the screen The call request is transmitted to the WWW server 31.

  In this case, the address of the first communication device 12, the address of the second communication device 13, designation of number notification / non-notification, and the address of the first communication device 12 notified to the second communication device 13 are a telephone number. , IP address, SIP address, etc., there is no specification of the value, depending on the fixed value set at the time of building this system, the default value set by the user, the value changed by the user as appropriate, the date, day of the week time zone An appropriate scheduled value may be used.

  Further, the communication is not limited to voice communication, but can be used for data communication such as FAX and image, and can be applied to any kind of communication assumed in the future.

  When the WWW server 31 receives the call request from the terminal device 11, the WWW server 31 searches the database for the address of the contractor based on the logged-in ID, and the first specified from the call request screen. While sending the call request to the application server 32 using the address of the communication device 12, the address of the second communication device 13, and the address of the WWW server 31 when notifying the information from the application server 32 to the WWW server 31, as parameters, In order to manage requests exchanged with the terminal device 11, a request identification ID is set for each call request from the terminal device 11 (S102).

  When the application server 32 receives a call request from the WWW server 31, the application server 32 sets a call identification ID for managing a call exchanged between the WWW server 31 and the application server 32, and sends the call to the WWW server 31. The identification ID is transmitted (S103).

  The WWW server 31 holds the request identification ID set for managing the exchange between the terminal device 11 and the WWW server 31 and the call identification ID received from the application server 32, and holds them together. Can be notified to the application server 32 via the WWW server 31.

  Next, the application server 32 searches the database based on the address of the contractor, acquires the address information of the SIP server 33 in which the contractor is accommodated, and transmits the call connection request INVITE as the caller (FROM). Address of the first communication device 12 that is the destination (TO), address to be notified to the second communication device 13 that is the calling ID notification header, designation of number notification / non notification, media A temporary value serving as information (SDP) is set and transmitted to the SIP server 33, and so far the call connection means to the first communication device 12 is established (S104).

  Here, by setting the contractor's address in the FROM indicating the originator, it is possible to process as if the contractor called, and when performing the billing process, the contractor can be charged. .

  Also, FROM = TO can be set. In this case, it is possible to set FROM as a specific address. Furthermore, in the case of an address such as a number @ IP address, a specific address is set even if only the number part matches. Make it possible.

  Note that the address of the SIP server 33 can also be transmitted from the WWW server 31. However, if the address of the SIP server 33 can be obtained by searching the database based on the address of the contractor, the corresponding contract can be obtained. It is assumed that the process of acquiring the address information of the SIP server 33 in which the person is accommodated is not performed.

  As a result of searching the database of the SIP server 33 in which the contractor is accommodated, when it is necessary to inquire the accommodation location from the accommodation location management server 36, the call connection is made from the application server 32 to the accommodation management server 36. It is possible to transmit the call connection request INVITE to the first communication device 12 by transmitting the request INVITE and transmitting the call connection request INVITE from the application server 32 to the SIP server 33 of the address set in the response. (S105).

  Next, when the response 200OK is returned from the first communication device 12 to the application server 32 via the SIP server 33, the second communication device 13 is transmitted via the SIP server 33 in which the contractor is accommodated. Call connection request INVITE is transmitted to the second communication device 13 (S106).

  As described above, the call connection request INVITE transmitted from the application server 32 to the SIP server 33 includes the address of the contractor in the source FROM, the address of the second communication device 13 in the destination TO, and the number notification / non-notification. The address to be notified to the second common device 13 is set in the designation and calling ID notification header, and the SDP included in the response 200 OK from the first communication device 12 is set in the media information SDP. Displays the address set in the calling ID header.

  When a response is returned from the first communication device 12 to the application server 32 via the SIP server 33, the application server 32 notifies the WWW server 31 whether the response is normal or abnormal, and the WWW server. By transferring a notification of the normal or abnormal result from 31 to the terminal device 11, the response status of the first communication device 12 can be confirmed from the terminal device 11 (S107).

  When the response 180Ringing is returned from the second communication device 13 to the application server 32 via the SIP server 33, the call connection request INVITE is transmitted from the application server 32 to the media server 34, and the media information of the call connection request INVITE is transmitted. The media information SDP included in the response 200OK from the first communication device 12 is set in the SDP (S108).

  When the response 200OK is returned from the media server 34 to the application server 32, the media including the response 200OK from the media server 34 to the first communication device 12 via the SIP server 33 in which the contractor is accommodated. A media information change request RE-INVITE in which the information SPD is set is transmitted, and at this time, a ringing tone is also sent to the first communication device 12 (S109).

  Here, there is no designation that the ringing tone is RBT, and another voice or video may be transmitted.

  When the response 200OK is returned from the second communication device 13 to the application server 32 via the SIP server 33, the application server 32 sends a call disconnection request BYE for stopping the ringing tone to the media server 34. Then, the media information change request RE-INVITE is transmitted to the first communication device 12 via the SIP server 33 in which the contractor is accommodated, and the media information change is transmitted from the application server 32 to the SIP server 33. In the media information SDP of the request RE-INVITE, the media information SDP included in the response 200OK from the second communication device 13 is set (S110).

  In the above-described embodiment, the procedure from S108 to S110 is omitted when the configuration does not include a media server.

  Next, when a response indicating whether the application server 32 is normal or abnormal is returned from the second communication device 13 via the SIP server 33, the response result is notified from the application server 32 to the WWW server 31. By transferring the response result from the terminal device 11 to the terminal device 11, it can be confirmed from the result display screen of the terminal device 11 whether or not the communication between the first communication device 12 and the second communication device 13 has been established. (S111).

  When the first communication device 12 normally processes the media information change request RE-INVITE, communication (call) is started between the first communication device 12 and the second communication device 13, and communication is established. (S112).

  When a response to the media information change request RE-INVITE is returned from the first communication device 12 to the application server 32 via the SIP server 33, a response result indicating whether the response is normal or abnormal is sent from the application server 32. By notifying the WWW server 31 and transferring the response result from the WWW server 31 to the terminal device 11, it is confirmed from the terminal device 11 whether the communication between the first communication device 12 and the second communication device 13 has been established. (S113).

  A call set from the application server 32 to the first communication device 12, a call set from the application server 32 to the second communication device 13, and a call set from the application server 32 to the media server 34 are: For management within 32, each call is connected as one communication.

  In the above-described embodiment, either the call to the first communication device 12 or the call to the second communication device 13 may be first, or may be made simultaneously. Furthermore, the object displayed on the screen of the terminal device 11 specified at the time of calling may be a figure or text, and can be selected on the screen. Further, the system indicates which of the displayed objects the user has selected. If it is detectable, there is no limitation in the method of displaying on a web browser etc. or implement | achieving with a dedicated application.

  Further, even if the terminal device 11 and the first communication device 12 are the same or different, there is no change in the above embodiment, and the call setting request can be made from either the IP network system or the PSTN network system as the source. There is no change in its action.

(Example 2)
Next, based on FIG. 3, an embodiment in which the first communication device is a mobile phone and the second communication device is a general telephone as an embodiment for establishing a call by making a call request from the terminal device 11. 2 will be described.

  Here, from the process in which the WWW server 31 authenticates the login of the user ID and the personal identification number from the terminal device 11 to the call preparation process in the application server 32 (S101 to S103 in FIG. 2), the second embodiment. Performs the same processing as in the first embodiment (illustrated as S201), and the processing after S103 will be described below.

  When the application server 32 notifies the WWW server 31 of the call identification ID, the application server 32 searches the database in the application server 32 based on the address of the contractor, and the address of the SIP server 33 in which the contractor is accommodated. The information is acquired and a call connection request INVITE is transmitted to the first communication device 12 via the SIP server 33, the gateway 35, the interconnection point 22, and the mobile phone network 23 in which the contractor is accommodated (S202). .

  In the FROM of the call connection request INVITE transmitted from the application server 32 to the SIP server 33, the address of the contractor is stored in the FROM, the address of the first communication device 12 is displayed in the TO, the number notification / non-notification designation, and the calling ID notification An address for communicating with the communication device is set as a header, and a temporary value is set as the media information SDP.

  At this time, by setting the address of the contractor in the FROM, it is possible to process the call as if the contractor had called, and the contractor using the system can be charged.

  Also, FROM = TO can be set. In this case, FROM can be set as a specific address. Further, in the case of an address such as number @ address, even if only the number part matches, the specific address Can be set.

  When the address of the SIP server 33 is specified and transmitted from the WWW server 31, the database in the application server 32 is searched based on the contractor address, and the SIP in which the contractor is accommodated. It is assumed that the process of acquiring the address information of the server 33 is not performed.

  When the search result of the database of the SIP server 33 in which the contractor is accommodated is a result of inquiring the accommodation position to the accommodation position management server 36, the application server 32 sends By transmitting the call connection request INVITE and transmitting the call connection request INVITE from the application server 32 to the SIP server 33 of the address set in the response, the first communication device 12 passes through the gateway 35 and the interconnection point 22. The call connection request INVITE is transmitted to (S203).

  When the response 200OK is returned from the first communication device 12 to the application server 32 via the mobile phone network 23, the interconnection point 22, the gateway 35, and the SIP server 33, the SIP server 33 in which the contractor is accommodated. The call connection request INVITE is transmitted to the second communication device 13 via the gateway 35, the interconnection point 22, and the other-party subscriber network 24 (S204). At this time, the call connection is transmitted from the application server 32 to the SIP server 33. In the request INVITE, the address of the contractor in FROM, the address of the second communication device 13 in TO, the classification of number notification / non-notification, the address to communicate with the communication device as the calling ID notification header, and the first as media information SDP The media information SDP included in the response 200OK from the communication device 12 is set.

  In this case as well, by setting the address of the contractor in the FROM of the call connection request INVITE, it is possible to process the call as if the contractor originated, and the billing process for the contractor can be performed.

  If the response 200OK is returned from the first communication device 12 to the application server 32 via the mobile phone network 23, the interconnection point 22, the gateway 35, and the SIP server 33, the application server 32 is normal as a response result. It is notified to the WWW server 31 whether it is abnormal (S205).

  The WWW server 31 can confirm the response status of the first communication device 12 from the terminal device 11 by transferring the response result from the application server 32 to the terminal device 11.

  When the response 183wSDP is returned from the second communication device 13 to the application server 32 through the other party's subscriber network 24, the interconnection point 22, the gateway 35, and the SIP server 33, the application server 32 is accommodated by the contractor. The media information change request RE-INVITE is transmitted to the first communication device 12 via the SIP server 33, the gateway 35, the interconnection point 22, and the cellular phone network 23 that are being used (S206).

  At this time, the media information SDP included in the response 183wSDP from the second communication device 13 is set in the media information SDP in the media information change request RE-INVTE transmitted from the application server 32 to the SIP server 33.

  The first communication device 12 normally processes the above-mentioned media information change request RE-INVITE to the application server 32, and responds 200 OK via the mobile phone network 23, the interconnection point 22, the gateway 35, and the SIP server 33. When the response 200OK is returned from the second communication device 13 via the other company's subscriber network 24, the interconnection point 22, the gateway 35, and the SIP server 33, the first communication device 12 and the second communication A call is started with the device 13 (S207).

  When the response 200OK is returned from the second communication device 13 to the application server 32 via each unit, the application server 32 notifies the WWW server 31 whether the response result is normal or abnormal, and the WWW server 31 Then, by transferring the response result to the terminal device 11, it is confirmed on the terminal device 11 whether or not communication (call) has been established between the first communication device 12 and the second communication device 13. Is possible.

(Example 3)
Next, a third embodiment when the contractor disconnects communication will be described with reference to FIG. Call disconnection is possible immediately after a call request is made from the terminal device 11, but here, call disconnection after communication between the first communication device 12 and the second communication device is established will be described.

  First, when disconnecting communication, the contractor selects and clicks communication to be connected from the screen of the terminal device 11.

  The terminal device 11 transmits a call connection request identification ID to the WWW server 31 in response to a click from the contractor, and the WWW server 31 uses the call connection request identification ID received from the terminal device 11 as the call connection request ID. The call ID is converted into an associated call identification ID, and transmitted to the application server 32 as a communication disconnection request parameter (S301).

  As described above, the application server 32 manages the relation between the call set from the application server 32 to the first communication device 12 and the call set from the application server 32 to the second communication device 13 as one communication. Therefore, the communication is disconnected by transmitting the call disconnect signal BYE to the first communication device 12 and the second communication device 13 via the SIP server 33 (S302).

  When the application server 32 transmits a call disconnect signal BYE to the first communication device 12 and the second communication device 13 to the SIP server, the application server 32 notifies the WWW server 31 that the disconnection instruction has been completed (S303). The WWW server 31 transfers the disconnection instruction completion notification notified from the application server 32 to the terminal device 11 so that the contractor can confirm that the communication is completed on the screen of the terminal device 11.

At that time, the application server 32 holds the address of the first communication device 12, the address of the contractor, the communication start time, and the charging ID as the charging information 1.

  Further, as in S106 processing, when the application server 32 transmits a call connection request INVITE to the second communication device 13, and the response 180Ringing is returned from the second communication device 13, the application server 32 holds the address of the second communication device 13, the address of the contractor, the communication start time, and the charging ID as the charging information 2. At this time, the charging ID is the same value as the charging ID of the first communication device 12. In addition to the billing information 2, the communication end time is held when the communication is disconnected.

  When the charging process is started from the connection response 200 OK of the first communication device 12, the charging information 1 and the charging ID of the charging information 2 are matched, the communication start time of the charging information 1 and the communication end time of the charging information 2 Then, the communication time is calculated, and the settlement process to the contractor is performed.

(Example 5)
Next, as a second billing processing method, a method for starting billing after communication between the first communication device 12 and the second communication device 13 is started will be described with reference to FIG.

  As shown in the figure, in response to the application server 32 transmitting a media information change request RE-INVITE to the first communication device 12 via the SIP server 33 (S109), a response is received from the first communication device 12. When 200OK is returned and the application server 32 receives the response 200OK, the address of the first communication device 12, the address of the second communication device 13, the address of the contractor, and the communication start time are stored as billing information. At the same time, when the communication is disconnected, the communication end time is held in addition to the above-mentioned information, thereby calculating the communication time from the communication start time and the communication end time, and performing a settlement process for the nine persons.

  As mentioned above, although the example of the apparatus and Example 1-5 corresponding to this was mentioned and demonstrated about embodiment of this invention, this invention is not necessarily limited only to the means and method, procedure, and procedure which were mentioned above.

In addition, it is also possible to schedule a fixed value set when this call control communication system is constructed, or an appropriate value according to the date, day of the week, time zone, or the like. Furthermore, these addresses can also track the position of each communication device as a call control communication system like mobile communication.

  Communication is not limited to voice communication, and data communication such as FAX and images can be used, and any type of communication that can be assumed in the future can be applied.

  The WWW server 31 accepts the continuous transmission request transmitted from the terminal device 11, stores the continuous transmission request, searches the database for the subscriber's address based on the logged-in user ID, and stores the stored continuous transmission request. , The address of the first communication device 12 designated on the continuous transmission request screen, the address of the second communication device 13, designation of address notification / non-notification to the second communication device 13, and second communication A continuous transmission request using the address notified to the device 13 and the address of the WWW server 31 for use when notifying the information from the application server 32 to the WWW server 31 is transmitted to the application server 32, and In order to identify requests exchanged between them, a request identification ID is set for each continuous transmission request from the terminal device 11. To (S102).

  The application server 32 receives the continuous transmission request transmitted from the WWW server 31, sets a call identification ID used for communication with the WWW server 31, and transmits the call identification ID to the WWW server 31 ( S103).

  Here, since the WWW server 31 receives the call identification ID and holds the call identification ID and the request identification ID in association with each other, the request transmitted from the terminal device 11 is sent to the application server 32 via the WWW server 31. Can be notified.

  The application server 32 searches the database based on the address of the contractor included in the received continuous transmission request, acquires the address information of the SIP server 33 in which the corresponding contractor is accommodated, and the SIP server 33 A call connection request (INVITE) is transmitted to the first communication device 12 via (step S104).

  In the call connection request transmitted here, the address of the contractor is set as the caller (FROM), the address of the first communication device 12 is set as the callee (TO), address notification / non-notification is specified, and the caller ID is notified. An address notified to the communication device is set in the header, and a temporary value is set in the SDP. By setting the address of the contractor in the FROM, it is possible to perform processing as if the contractor originated, and when performing billing processing, the contractor can be charged.

  In addition, the FROM address and the TO address can be the same. In this case, the FROM can be set to a specific address. In addition, in the case of an address such as number @ IP address, even if only the number part matches, it can be set as a specific address.

  When the address of the SIP server 33 is specified in the call connection request transmitted from the WWW server 31, the database is searched based on the address of the contractor, and the corresponding contractor is accommodated. The process of acquiring the address information of the existing SIP server 33 is not performed.

  As a result of searching the database of the SIP server 33 in which the contractor is accommodated, the application server 32 transmits INVITE to the accommodation location management server 36 when it is necessary to inquire the accommodation location management server 36 about the accommodation location. Then, a call connection request (INVITE) is transmitted to the first communication device 12 via the SIP server 33 having the address set in the response (S105).

  The application server 32 receives the response (200 OK) from the first communication device 12 via the SIP server 33, and the SDP of the first communication device 12 set in the response (hereinafter, “first SDP”). And a response result indicating normality or abnormality is notified to the WWW server 31 (S106).

  The WWW server 31 transfers the notified response result to the terminal device 11, so that the user can confirm the connection result and connection state of the first communication device 12 on the terminal device 11.

  Subsequently, the application server 32 transmits a call connection request (INVITE) to the second communication device 13 via the SIP server 33 in which the contractor is accommodated (S107).

  The call connection request transmitted here includes the address of the contractor as the caller (FROM), the address of the second communication device 13 as the callee (TO), the address notification / non-notification designation, and the caller ID notification. The address notified to the second communication device 13 is set in the header, and the first SDP stored in (S106) is set in the SDP. By setting the address of the contractor in the FROM, it is possible to perform processing as if the contractor originated, and when performing billing processing, the contractor can be charged.

  After receiving the response (180 Ringing) from the second communication device 13 via the SIP server 33, the application server 32 transmits a call connection request (INVITE) in which the first SDP is set to the media server 34 (S108). ).

  The application server 32 stores the SDP transmitted from the media server 34, and the media information change request (RE-INVITE) in which the SDP is set in the first communication device 12 via the SIP server 33 in which the contractor is accommodated. ) Is transmitted (S109).

  At this time, a ringing tone flows through the first communication device 12. This ringing tone may be a voice other than the ringing tone RBT (Ring Back Tone) or may be a video.

  The application server 32 receives the response (200 OK) from the second communication device 13 via the SIP server 33 after the second communication device 13 responds to the call connection request (INVITE) in (S107). The SDP of the second communication device 13 set in the response (hereinafter referred to as “second SDP”) is stored, and a response result indicating normality or abnormality is notified to the WWW server 31 (S110).

  The WWW server 31 displays the notified response result on the screen of the terminal device 11, so that the user can check the connection result and connection state of the second communication device 13 on the terminal device 11.

  After receiving the response (200 OK) from the second communication device 13 via the SIP server 33, the application server 32 transmits a call disconnection request (BYE) for stopping the ringing tone to the media server 34, and contracts. The media information change request (RE-INVITE) in which the second SDP is set is transmitted to the first communication device 12 via the SIP server 33 in which the user is accommodated (S111).

  At this time, the first communication device 12 normally processes the media information change request (RE-INVITE), so that communication between the first communication device 12 and the second communication device 13 is performed. The call is established and can be made (S112).

  After receiving the response to the media information change request (RE-INVITE) in (S111), the application server 32 notifies the WWW server 31 of a response result indicating normality or abnormality (S113).

  The WWW server 31 displays the notified response result on the screen of the terminal device 11, so that the user establishes communication between the first communication device 12 and the second communication device 13 using the terminal device 11. Can be confirmed.

  The application server 32 notifies the WWW server 31 of the disconnection state when a disconnection signal (BYE) is transmitted from the second communication device 13 via the SIP server 33 (S114).

  The WWW server 31 displays the notified disconnection state on the screen of the terminal device 11, so that the user can confirm the call release by the second communication device 13 on the terminal device 11.

  The application server 32 receives the disconnection signal (BYE) from the second communication device 13 via the SIP server 33, and then sets the final SDP received from the first communication device 12 in the media server 34. A request (INVITE) is transmitted (S115).

  Here, the final SDP received from the first communication device 12 is, for example, a call connection request (INVITE) when the value included in the SDP is not changed during the communication of the first communication device 12. When the SDP set in the response to) is set and the value is changed, the SDP changed by the media change request (RE-INVITE) transmitted from the first communication device 12 or the changed media information The SDP set in the response to the change request (RE-INVITE) is set.

  The application server 32 receives the response (200 OK) from the media server 34, stores the SDP set in the response, and then transmits the response from the media server 34 via the SIP server 33 in which the contractor is accommodated. A media information change request (RE-INVITE) in which this SDP is set is transmitted to the first communication device 12 (S116).

  At this time, the first communication device 12 displays a medium for recognizing that the second communication device 13 has released the call. As the media, for example, any content such as a sound source such as a busy tone BT (Buzy Tone) and a guidance, a video, and the like can be used. In addition, when the connection processing for this continuous call request ends, such as when the number of connections between the first communication device 12 and another communication device reaches the upper limit on this system, a medium indicating that is used. It is also possible to send it out.

  Subsequently, from the continuous transmission request screen displayed on the terminal device 11, the user addresses the third communication device 14, the address to the third communication device 14 (ID of the first communication device 12 that is the calling side). ) Designation of notification / non-notification, address to notify the third communication device 14 (ID of the first communication device 12 that is the calling side), and the request identification ID set in (S102) Click the request button for the object.

  The WWW server 31 accepts the continuous transmission request transmitted from the terminal device 11 again, the address of the third communication device 14 designated on the continuous transmission request screen, and the number notification / non-notification to the third communication device 14. , The address notified to the third communication device 14, and a continuous transmission request using the call identification ID set in (S 103) related to the request identification ID as a parameter is transmitted to the application server 32 (S 117).

  The application server 32 receives the continuous call request transmitted from the WWW server 31, checks whether the call identification ID is already managed, and if the call identification ID is managed, Accept. (S118).

  The application server 32 reads the call connection information that has already been implemented in the first communication device 12 managed based on the call identification ID, and passes through the third SIP server 33 that accommodates the contractor. A call connection request (INVITE) is transmitted to the communication device 14 (S119).

  The call connection request transmitted here includes the address of the contractor as the caller (FROM), the address of the third communication device 14 as the callee (TO), designation of address notification / non-notification, and caller ID notification. The address notified to the third communication device 14 is set in the header, and the final SDP received from the first communication device 12 is set in the SDP. By setting the address of the contractor in the FROM, it is possible to perform processing as if the contractor originated, and when performing billing processing, the contractor can be charged.

  After receiving the response (180 Ringing) from the third communication device 14 via the SIP server 33, the application server 32 transmits a guidance change request (INFO) to the media server 34, and the first communication is performed in (S115). From the media sent to the device 12, an instruction to change to the ringing tone or the like is given so that the first communication device 12 can recognize that the third communication device 14 is in the calling state (S120).

  Since it is only necessary to be able to instruct media change, methods such as RE-INVITE, MESSAGES, and other means may be used in addition to INFO.

  The application server 32 receives the response (200 OK) from the third communication device 14 via the SIP server 33 after the third communication device 14 responds to the call connection request (INVITE) in (S119). Then, the SDP (hereinafter referred to as “third SDP”) of the third communication device 14 set in the response is stored, and a response result indicating normality or abnormality is notified to the WWW server 31 (S121).

  The WWW server 31 displays the notified response result on the screen of the terminal device 11, so that the user can check the connection result and connection state of the third communication device 14 on the terminal device 11.

  After receiving the response (200 OK) from the third communication device 14 via the SIP server 33, the application server 32 transmits a call disconnection request (BYE) for stopping the ringing tone to the media server 34, and the contract is made. The media information change request (RE-INVITE) in which the third SDP is set is transmitted to the first communication device 12 via the SIP server 33 in which the user is accommodated (S122).

  At this time, the first communication device 12 normally processes the media information change request (RE-INVITE), so that communication between the first communication device 12 and the third communication device 14 is performed. It is established and a call is possible (S123).

  After receiving the response to the media information change request (RE-INVITE) in (S122), the application server 32 notifies the WWW server 31 of a response result indicating normality or abnormality (S124).

  The WWW server 31 displays the notified response result on the screen of the terminal device 11, so that the user establishes communication between the first communication device 12 and the third communication device 14 using the terminal device 11. Can be confirmed.

  When the disconnection signal (BYE) is transmitted from the third communication device 14 via the SIP server 33, the application server 32 notifies the WWW server 31 of the disconnection state (S125).

  The WWW server 31 displays the notified disconnection state on the screen of the terminal device 11, so that the user can confirm the call release by the third communication device 14 on the terminal device 11.

  The application server 32 receives the disconnection signal (BYE) from the third communication device 14 via the SIP server 33 and then sets the final SDP received from the first communication device 12 in the media server 34. A request (INVITE) is transmitted (S126).

  Here, the final SDP received from the first communication device 12 is, for example, a call connection request (INVITE) when the value included in the SDP is not changed during the communication of the first communication device 12. When the SDP set in the response to) is set and the value is changed, the SDP changed by the media change request (RE-INVITE) transmitted from the first communication device 12 or the changed media information The SDP set in the response to the change request (RE-INVITE) is set.

  The application server 32 receives the response (200 OK) from the media server 34, stores the SDP set in the response, and then transmits the response from the media server 34 via the SIP server 33 in which the contractor is accommodated. A media information change request (RE-INVITE) in which this SDP is set is transmitted to the first communication device 12 (S127).

Further, when communication is performed between the first communication device 12 and another communication device, a continuous transmission request is issued from the first communication device 12 in the same manner as the processing described in (S117) to (S127). The process of transmitting, establishing communication with the other communication device of the connection destination, and repeatedly disconnecting is performed. In this embodiment, after the communication between the first communication device 12 and the Nth communication device 15 is completed, it is disconnected by the Nth communication device 15 and the call is released by the Nth communication device 15. This shows a state where possible media is transmitted to the first communication device 12 (S128).

  When the disconnection signal (BYE) is transmitted from the first communication device 12 via the SIP server 33, the application server 32 transmits a disconnection signal (BYE) to the media server 34, and the disconnection state is transmitted to the WWW server 31. Notification is made (S129).

  The WWW server 31 transfers the notified disconnection state to the terminal device 11 so that the user can confirm the call release by the first communication device 12 on the terminal device 11.

  The call set from the application server 32 to the first communication device 12, the call set from the application server 32 to the second communication device 13, and the call set from the application server 32 to the third communication device 14. The call and the call set from the application server 32 to the media server 34 are managed in association with each other as one communication within the application server 32.

  As a method for setting each parameter on the continuous transmission request screen, text input or a method for allowing the user to select data by outputting data already stored in the WWW server 31 to the screen is also possible. In addition, as a method for executing a continuous transmission request after setting each parameter, a method of clicking an object or a figure displayed with a button or the like output to the terminal device 11 is also possible. That is, as long as the setting content by the user can be detected by the WWW server 31, it may be realized by a Web browser or may be realized by another application.

  Further, the terminal device 11 that makes the request and the first communication device 12 may be the same or different. Furthermore, the call connection request transmitted from the terminal device 11 may originate from the IP network system, and there is no change in the operation of either system in the PSTN network.

  In the processing described in the present embodiment, when a call connection request is made from the application server 32 to the media server 34, a certain medium is always sent to the first communication device 12, so that the medium need not be sent. When the call release is performed at this point, but it is not necessary to send the media, a guidance change request (INFO) is transmitted to temporarily stop sending the media and to the first communication device 12. It is also possible to transmit a guidance change request (INFO) again when it becomes necessary to send the media.

  According to the present embodiment, the application server 32 performs the first communication when the communication between the established first communication device 12 and the second communication device 13 is disconnected by the second communication device 13. The call connection request set with the SDP transmitted from the device 12 is transmitted to the third communication device 14 via the SIP server 33. After the third communication device 14 responds to the call connection request, Since the media information change request set with the SDP transmitted from the third communication device 14 is transmitted to the first communication device 12 via the SIP server 33, the call setting with the first communication device 12 is retained. Thus, the communication partner of the first communication device 12 can be switched from the second communication device 13 to the third communication device 14, and communication between the first communication device 12 and the third communication device 13 can be performed. Easy to use when establishing It can be.

  According to this embodiment, after the application server 32 transmits a call connection request to the second communication device 13 and / or after transmitting a call connection request to the third communication device 14, the SIP server 33 is activated. Since the calling state is notified to the first communication device 12 via the communication, the communication between the first communication device 12 and the second communication device 13 and / or the first communication device 12 and the third communication. The user using the first communication device 12 can be made aware that communication with the device 14 is being established.

  According to the present embodiment, when the communication between the established first communication device 12 and the second communication device 13 is disconnected by the second communication device 13, the application server 32 sets the SIP server 33. Since the disconnection is notified to the first communication device 12 via the first communication device 12, the first communication device 12 uses the fact that the communication between the first communication device 12 and the second communication device 13 has been disconnected. The user can be made aware.

  According to this embodiment, the application server 32 acquires each connection result and connection state for each call connection request and notifies the WWW server 31. The WWW server 31 transmits the notified connection result and connection state to the terminal. Since it is displayed on the screen of the device 11, the user operating the terminal device 11 can surely grasp the connection result and connection state for each call connection request, and the convenience of the call control communication system can be improved. .

  According to the present embodiment, since the SIP server 33 is connected to the gateway 35 that connects the different communication networks, even if the communication device is connected to the subscriber network of a different communication carrier, Communication between each communication device can be established reliably.

  According to the present embodiment, since the transmission source set in each call connection request is set and transmitted to the user who has made the continuous call request, all communication charges for each call connection request are sent to the continuous call request. Users can be charged.

  According to the present embodiment, since the call information established by the first communication device 12, the second communication device 13, and the third communication device 14 is managed in association with each other, the timing for starting charging can be set flexibly. can do.

  According to the present embodiment, the application server sets the caller ID information notified to the second communication device 13 in the call connection request, and sets the caller ID information notified to the third communication device 14 as the call connection request. Since it is set, it is possible to flexibly set the caller ID to be called back.

  Thereafter, when the application server 32 receives a disconnection signal (BYE) from the second communication device 13, the application server 32 adds the communication end time to the billing information and stores it, and stores the first communication device 12 and the second communication device. 13 is charged to the contractor as communication with 13 (S502).

  Similarly, the application server 32 transmits a media information change request (RE-INVITE) to the first communication device 12, and when a response (200 OK) is returned, the address of the first communication device 12 and the first The address of the third communication device 14, the address of the contractor, and the communication start time are associated and stored as billing information (S503).

  Thereafter, when the application server 32 receives a disconnection signal (BYE) from the third communication device 14, the application server 32 adds the communication end time to the billing information and stores it, and the first communication device 12 and the third communication device. 14 is charged to the contractor as communication with the network 14 (S504).

  Next, with reference to the attached drawings, a system example and a corresponding example will be described with respect to a third embodiment of the present invention.

  FIG. 9 is a configuration diagram showing a call control communication system according to the third embodiment of the present invention. The call control communication system shown in the figure is configured such that an application server interface 41 is further provided between the application server 32 and the SIP server 33. Other configurations are the same as those of the call control communication system described in the second embodiment, and therefore, a duplicate description is omitted here.

  In the call control communication system shown in the second embodiment, it is assumed that the communication carriers operating the application server 32 and the SIP server 33 are the same. This assumes that the operators to be operated are different.

  Depending on the network policy of the telecommunications carrier that provides the communication service between the communication devices using the SIP server 33, the information of the first communication device 12 may be notified to other communication devices according to the instruction of the application server 32. It may not be acceptable. For example, it is assumed that address information and caller ID information other than those assigned to the application server 32 are not allowed to be set in the call connection request (INVITE).

  In such a case, in order for the SIP server 33 to accept an instruction from a specific application server 32, a means for allowing communication between the application server 32 and the SIP server 33 is required. Hereinafter, an example applied to the call control communication system according to the present embodiment will be described with reference to FIG.

(Example 11)
The WWW server 31 performs the same processing as (S101) to (S104) described in (Example 6) (S601).

  The application server 32 transmits a call connection request (INVITE) in which association request information for requesting an address and caller ID information related to the first communication device 12 is set to the SIP server 33 (S602).

  When the association request information is set in the call connection request transmitted from the application server 32, the SIP server 33 accepts the association request for this call connection request, and manages that the call is an association request target call. Then, a call connection request (INVITE) is transmitted to the first communication device 12 (S603).

  Note that no association request is set in the call connection request transmitted to the first communication device 12.

  After receiving the normal response (200 OK) from the first communication device 12, the SIP server 33 generates an association identifier as a unique value as a call control system such as a random number and sets the first response set as the normal response. SDP and / or caller ID information, which is unique information of the communication device 12 and the association identifier thereof, are associated with each other and stored and managed in the storage unit, and the association identifier and the SDP and / or caller ID information are A normal response (200 OK) is set and transmitted to the application server 32 (S604).

  Subsequently, the same processing as (S106) described in (Example 6) is performed (S605).

  The application server 32 transmits a call connection request (INVITE) to the second communication device 13 via the SIP server 33 in which the contractor is accommodated (S606).

  In the call connection request transmitted here, the association identifier transmitted in (S604) and SDP and / or caller ID information are set.

  When the association identifier is set in the call connection request transmitted from the application server 32, the SIP server 33 reads the association identifier stored in the storage unit and searches for whether the association identifier has already been created. In the case of the created association identifier, the related SDP and / or caller ID information is read and compared. If the comparison results match, this call connection request is permitted, and a call connection request (INVITE) in which SDP and / or caller ID information is set is transmitted to the second communication device 13 (S607).

  Note that no association identifier is set in the call connection request transmitted to the second communication device 13. It is also possible to compare using all of the association identifier, caller ID information, and SDP.

  Thereafter, the same processing as (S108) described in (Embodiment 6) is performed. However, at the time of transmission of the media information change request (RE-INVITE) to the first communication device 12 and at the time of transmission of the call connection request (INVITE) to the third communication device 14 or the Nth communication device 15, Similar association processing is performed between the application server 32 and the SIP server 33 (S608).

  In this embodiment, the caller ID information set in the normal response (200 OK) from the first communication device 12 is managed by the SIP server 33, and the call connection request (INVITE) to the second communication device 13 is managed. The caller ID information set in () is collated, but the SIP server 33 can perform a process in which collation is not performed. In this case, it is possible to cope with spoofing of the caller information by authenticating the caller number information set from the terminal device 11 or the like with the WWW server 31 or the application server 32.

  Furthermore, the SIP server 33 can transmit a normal response (200 OK) in which the association identifier is set to the application server 32 without setting SDP and / or caller ID information in (S604). In that case, the application server 32 does not set a value in the SDP and / or caller ID information or sets a dummy value in (S606), and sends a call connection request (INVITE) in which the association identifier is set to the SIP. Send to server 33. In step S607, the SIP server 33 compares the received association identifier with the association identifier stored in the storage unit, and if the comparison result matches, the SIP server 33 sets the SDP and / or caller ID information. A connection request (INVITE) is transmitted to the second communication device 13. Thereby, since it is not necessary to transmit SDP to the telecommunications carrier that operates the application server 32, it becomes possible to handle information possessed by the telecommunications carrier that operates the SIP server 33 in a secret manner.

  According to the present embodiment, the SIP server 33 transmits a call connection request to the first communication device 12 based on the call connection request transmitted from the application server 32, and the first connection is made in response to the call connection request. After receiving the SDP and / or caller number information transmitted from the communication device 12, the received SDP and / or caller number information and the generated association identifier are stored in association with each other, and the SDP and / or caller number information is stored. And the association identifier are read out and transmitted to the application server 32. When the call connection request in which the SDP and / or caller identification information and the association identifier are set is received from the application server 32, the received SDP and / or transmission is received. Each of the person identification information and the association identifier, and the stored SDP and / or caller number information and the association identifier. When the comparison results match, a call connection request is transmitted to the second communication device 13, so that the SIP server 33 provides a call connection control and Unlike network operators that provide additional service control in the application server 32, the network policy that does not allow the application server 32 to transmit information of the first communication device 12 to the second communication device 13 is defined. Even in the case of the SIP server 33, communication between the first communication device 12 and the second communication device 13 can be reliably established.

  Finally, the terminal device 11, the WWW server 31, the application server 32, and the SIP server 33 described in all the embodiments are configured by a computer, and each process is executed by a program. Also, each process is recorded as a program, for example, on a recording medium such as a CD or FD, and the recording medium is incorporated into a computer, or the program recorded on the recording medium is downloaded to a computer via a communication line. Of course, the functions described above can be processed by installing the program from a recording medium and operating the computer with a program. By using such a recording medium, it is possible to improve the distribution. Is.
