Description

  The present invention relates to a technology for automatically setting information for a VoIP (Voice over Internet Protocol) terminal used in an IP telephone service.

  An IP telephone service provided with 0AJ numbers (also referred to as 0AB to J numbers) used in conventional subscriber telephones has begun to be provided by communication carriers.

  In the IP telephone service using the 0AJ number, the telephone number and the place (line) where the VoIP terminal is used must be connected one-to-one in the system, as in the case of a conventional subscriber telephone. In such an IP telephone service corresponding to the 0AJ number, each VoIP terminal setting is in charge of construction from the viewpoint of preventing spoofing by setting the VoIP terminal to a line different from the line to which it is connected. Had to be done manually at the user's home. Furthermore, even when it is necessary to change the setting of the VoIP terminal due to application from the user or the convenience of the network side, it is necessary for the construction staff to go to the user's home and perform manual setting. Further, from the viewpoint of security, the VoIP terminal cannot be remotely operated from the network side.

  Furthermore, when changing the setting of a telephone number or the like, if there is a time lag between the change of the setting information on the network side and the change of the setting information of the VoIP terminal, a period during which the user cannot use the IP telephone service occurs. Therefore, it is necessary to pay attention to the network side construction staff and the network side construction staff in order to change the setting information on the network side and the setting information on the VoIP terminal as simultaneously as possible.

  Further, manual setting of setting information by a construction worker is not a desirable setting method from the viewpoint of personal information protection because the printed setting information is referred to.

As a related technique, Patent Document 1 discloses a technique for automatically setting a VoIP terminal adapter.

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

(System overview)
FIG. 1 shows a configuration example of a communication system according to an embodiment of the present invention. FIG. 1 shows an example in which a VoIP terminal 10 is fixedly used in a place (room) and a VoIP session and a PC PPP session can be established via a DSLAM 30 (Digital Subscriber Line Access Multiplexer). .

  The VoIP communication system corresponding to 0AJ shown in FIG. 1 includes a DHCP server 40 that holds fixed IP addresses in association with each line, a terminal setting system 20 that automatically sets VoIP terminals 10, and a call control server 50 (CA ). For PC communication, a BAS 60 (Broadband Access Server) for establishing a PC session is provided.

  In the present embodiment, “line” is a path identified by VLANID. That is, the DHCP server stores the VLAN ID and the IP address in association with each other. Hereinafter, information for identifying a line is referred to as line identification information.

  Next, an outline of the operation of the VoIP communication system when information such as a telephone number is set in the VoIP terminal 10 will be described with reference to FIG.

  First, the operator registers setting information such as a telephone number and a fixed IP address assigned to a line where the VoIP terminal is used in the terminal setting system 20 (step 1).

  When the user of the VoIP terminal 10 turns on the power of the VoIP terminal 10, the DHCP server 40 gives a fixed IP address assigned to the line to the VoIP terminal 10, and the VoIP terminal 10 uses the IP address as the source IP address. The terminal setting system 20 is accessed (step 2). When the IP address of the VoIP terminal 10 matches the registered IP address, the terminal setting system 20 downloads setting information corresponding to the IP address to the VoIP terminal 10 (step 3).

  The VoIP terminal 10 notifies the terminal setting system 20 that the setting information has been set, and the terminal setting system transmits the setting information of the VoIP terminal 10 to the call control server 50 when the notification is received. (Step 4). In the call control server 50, information necessary for VoIP communication of the VoIP terminal 10, such as a telephone number, is set.

  As described above, when the VoIP terminal 10 performs IP communication with the terminal setting system 20, it is possible to automatically set information that has been manually set in the VoIP terminal 10 by a person in charge of construction.

Hereinafter, each device will be described in detail.
(Configuration of each device)
FIG. 2 shows a configuration example of the VoIP terminal 10 and the terminal setting system 20. As shown in FIG. 2, the terminal setting system includes a Web server 21, an application server 23, a database server 24, and a Web server 22.

  The application server 23 is a server that processes data in cooperation with each server. The database server 23 is a server that holds information such as order information input from the operator terminal 70, setting information for the VoIP terminal, and an access log from the VoIP terminal. The Web server 21 is a server that receives an HTTP and HTTPS request from the VoIP terminal 10 to the terminal setting system 20 and returns a response to the request. The Web server 22 is a server that receives order information from the operator terminal 70 to the terminal setting system 20 and returns a response.

  In the example of FIG. 2, each server is composed of one or a plurality of computers, but a plurality of servers can be realized using a single computer.

  The VoIP terminal 10 includes a network communication function unit 11 for performing IP communication, a VoIP communication processing unit 12 for realizing 0AJ-VoIP communication, and an automatic setting processing unit 13 for performing setting information automatic setting processing according to the present invention. A PC communication processing unit 14 for realizing PC communication is provided.

  The VoIP terminal 10 has a configuration in which a computer including a CPU, a memory, and the like is provided with a communication interface as hardware, and each functional unit described above is realized by a program executed by the hardware and the VoIP terminal 10. It is.

(Processing sequence)
Next, an example of a processing sequence in the system having the above configuration will be described with reference to FIG.

  First, the operator inputs order information from the operator terminal 70, and the operator terminal 70 transmits the order information to the Web server 22 (step 11). The order information includes an IP address given to the information setting target VoIP terminal 10, a PPP-ID for PPP communication, a PPP-PWD, a telephone number for VoIP communication, a service domain, a VoIP user ID, and a VoIP user PWD. , And the address of the CA. The operator can refer to correspondence information between a location (line) and an IP address, and inputs an IP address to be set in a VoIP terminal installed at a specific location based on the correspondence information.

  The order information transmitted to the Web server 22 in step 11 is registered in the database server 24 (step 12).

  When the power of the VoIP terminal 10 is turned on by the user, the VoIP terminal 10 sends an IP address issue request to the DHCP server 40 (step 13). The IP address issue request is given line identification information (VLAN-ID or the like) by a network function and is sent to the DHCP server 40.

  The DHCP server 40 returns an IP address corresponding to the line identification information to the VoIP terminal 10 that is the IP address issue request source (step 14). The VoIP terminal 10 uses this IP address as its own IP address.

  Thereafter, in the example shown in FIG. 3, the VoIP terminal 10 transmits an update information confirmation request to the Web server 22 using HTTP (step 15). The Web server 2 sends a confirmation request to the application server 23 (step 16). The application server 23 refers to the database server 24 using the IP address of the request transmission source as a key (step 17), and checks whether there is update information that has not been downloaded (step 18). When the order information is updated from the operator terminal 70, the database server 24 has the update information “present” information until the updated information is downloaded by the VoIP terminal 10, and is downloaded by the information. It can be determined whether there is no update information.

  The update information confirmation response is returned to the web server 22 (step 19), and the web server 22 transmits an update information confirmation request response to the VoIP terminal 10 (step 20). Hereinafter, a case where there is update information will be described.

  When it is confirmed that there is update information to be downloaded, the VoIP terminal 10 transmits a setting information download request to the Web server 21 using HTTPS (step 21). The setting information download request is sent to the application server 23 (step 22). The application server 23 refers to the database server 24 using the IP address of the VoIP terminal 10 as a key (step 23), and acquires setting information corresponding to the IP address (step 24).

  The application server 23 returns a setting information request response including setting information to the Web server 21 (Step 25), and the Web server 21 downloads the setting information to the VoIP terminal 10 using HTTP (Step 26).

  The VoIP terminal 10 performs setting (processing such as storing each setting information in a predetermined location of the storage device) based on the downloaded setting information, and after the setting is completed, a setting completion report indicating that the setting is completed is sent to the Web server. 21 (step 27). The Web server 21 returns a setting completion report receipt response to the VoIP terminal 10 (step 28) and transfers the setting completion report (step 29). Further, the application server 23 transmits setting information to the call control server 50 in response to receiving the setting completion report (step 30). The operator terminal 70 may transmit the setting information to the call control server 50 in response to receiving the setting completion report. The call control server 50 that has received the setting information performs settings necessary for VoIP communication of the VoIP terminal based on the setting information.

(Operation details of VoIP terminal)
Next, the operation of the VoIP terminal 10 when the power is turned on will be described in detail with reference to the flowchart of FIG. The following operations are mainly executed by the automatic setting processing unit 13.

  The VoIP terminal 10 transmits an IP issue request to the DHCP server 40 when the power is turned on (step 40) (step 41). When the VoIP terminal 10 confirms the acquisition of the IP address (step 42), the VoIP terminal 10 checks whether or not the IP address acquired this time is the same as the IP address acquired when the power was last turned on (step 43). If they are the same, it is checked whether setting information is held (step 44). If the IP addresses are not the same in step 43 or the setting information is not held in step 44, the VoIP terminal 10 accesses the terminal setting system 20 using HTTPS and acquires the setting information (step 45). Then, it restarts itself to validate the setting (step 46).

  When the setting information is held in step 44, the VoIP terminal 10 accesses the terminal setting system 20 using HTTP and confirms whether or not there is update information (step 47). As a result of the confirmation (step 48), if there is update information, the terminal setting system is accessed using HTTPS and the setting information is acquired (step 45).

  If there is no information to be updated in step 48, the terminal is activated (step 49). However, when the setting information in the VoIP terminal 10 is changed after the power is turned on by the user, the setting completion report is issued immediately after step 48. Is transmitted to the terminal setting system 20.

  Thereafter, in a state where the VoIP terminal 10 is activated, the VoIP terminal 10 periodically accesses the terminal installation system 20 to check update information, and if there is information to be updated, the procedure shown in FIG. 4 is set. Get information, configure settings, and send a configuration completion report. This eliminates the need for maintenance by construction personnel.

  The time interval for periodic access may be set in the VoIP terminal 10 in advance, or each time the VoIP terminal 10 accesses the terminal setting system 20, the terminal setting system 20 sets the next access date and time. The VoIP terminal 10 may be accessed at the date and time notified. When the terminal setting system 20 notifies the VoIP terminal 10 of the next access date and time, the terminal setting system 20 considers the access date and time from other VoIP terminals so that accesses from a plurality of VoIP terminals are dispersed in time. Set the date and time that each VoIP terminal should access.

  Further, as described above, HTTP is used for confirmation of update information and the like, and communication is performed using HTTPS only when download is necessary. Therefore, the load on the Web server in the terminal setting system 20 can be reduced.

(Operation details on the terminal setting system side)
Next, the operation on the terminal setting system side will be described. First, the operation of the terminal setting system 20 when placing an order from the operator terminal 70 will be described with reference to the flowchart of FIG.

  In response to an operation from the operator terminal 70, the terminal setting system 20 transmits a login screen to the operator terminal 70 (step 51). The terminal setting system 20 receives the operator ID and password from the operator terminal 70 and authenticates them (step 52). If the authentication is OK, the order information input from the operator terminal 70 is received (step 53), and the order information is stored in the database server 24 (step 54). Then, information indicating that the undownloaded update information is “present” is set (step 55).

  Next, the operation of the terminal setting system 20 when there is an access from the VoIP terminal 10 will be described with reference to the flowchart of FIG. The following processing is mainly executed by an application program in the application server 23.

  When the terminal setting system 20 receives an access from the VoIP terminal 10 (step 61), IP address authentication is performed by confirming that the IP address of the VoIP terminal 10 that is the access source is included in the registered IP address. (Step 62). By using the line identification information, authentication is performed based on whether or not the IP address registered corresponding to the line identification information of the accessed line matches the IP address of the VoIP terminal 10 included in the access data. You may go.

  The terminal setting system 20 identifies whether the access from the VoIP terminal 10 is a confirmation of update information or a setting information download request (step 63). This identification may be performed by referring to the contents of the access data, or may be identified by whether the access is HTTP (when updating information is confirmed) or HTTPS (when downloading is requested).

  If it is determined in step 63 that the access from the VoIP terminal 10 is confirmation of the update information, the terminal setting system 10 confirms the contents of the database server, and informs the VoIP terminal 10 whether there is update information to be downloaded. Then, the communication with the VoIP terminal 10 is terminated (step 65). Note that the communication with the VoIP terminal 10 is also terminated when the IP address authentication in step 62 fails.

  If it is determined in step 63 that the access from the VoIP terminal 10 is a download request, the terminal setting system 20 acquires setting information corresponding to the access source VoIP terminal 10 based on the IP address of the VoIP terminal 10 ( Step 66), the setting information is transmitted to the VoIP terminal 10 (Step 67). When the setting at the VoIP terminal 10 is completed and a setting completion notification is received from the VoIP terminal 10 (step 68), the terminal setting system 20 ends the communication with the VoIP terminal 10 (step 69). Then, the setting information corresponding to the VoIP terminal 10 is transmitted to the call control server 50 (step 70), and the update information is set to “none” (step 71). When the update information is “present”, only the update information may be transmitted to the VoIP terminal.

  As described above, the information setting for the call control server 50 is performed immediately after the terminal setting information is downloaded to the VoIP terminal 10, so that the opening of the VoIP network side and the opening of the VoIP terminal 10 can be synchronized. Thus, it is possible to prevent the VoIP communication from being unusable due to the inconsistency between the VoIP network and the labor of the person in charge of construction on the VoIP network side and the VoIP terminal side as in the conventional case.

  Further, the terminal setting system 20 authenticates the VoIP terminal 10 using the IP address assigned based on the line connected to the VoIP terminal 10 as a key and downloads the setting information, but the VoIP terminal 10 moves. Then, when connected to another line, an IP address different from the previous one is issued to the VoIP terminal 10 after movement. As shown in FIG. 4, the VoIP terminal 10 detects that the IP address is different from the previous one, accesses the terminal setting system 20, and downloads setting information corresponding to the changed IP address. Thereby, it is possible to prevent a VoIP terminal connected to a specific line from performing VoIP communication using setting information corresponding to a line other than the line.

  In the example described so far, the VoIP terminal 10 side is leading the terminal setting system 20, but the terminal setting system 20 can also issue an operation instruction to the VoIP terminal 10. The operation instruction is, for example, terminal resetting, terminal internal operation log update, or the like.

  In this case, an authentication ID is registered in advance in the VoIP terminal 10. Then, the terminal setting system 20 sends a UDP packet including an authentication ID and an operation instruction to the VoIP terminal 10, and the VoIP terminal 10 receives the UDP packet, confirms the authentication ID, and then, for example, the terminal setting system 20 according to the operation instruction. To make a download request. By providing such a function, the VoIP terminal 10 can be accessed to the terminal setting system 20 without manual operation by the user.

  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.
