4 is a diagram illustrating a sequence of terminal usage registration.

In a method of controlling registration and restriction of use in an unlicensed area, the VoIP terminal 10 can be used only after first registering the terminal. Unlicensed area means an area other than the area registered to use an internet terminal when subscribing to a service. Terminal registration is made when the first LAN line is connected to the terminal. For initial terminal registration, a registration request is made by a SIP register message to the originating soft switch 700 together with its IP address information (S401, S402). The IP address information of the calling terminal 10 is delivered in the header portion of the SIP register message. In this case, when the calling terminal 10 has a private IP address, an IP router (not shown) passes through the IP sharing apparatus, and the IP converter 600 converts the private IP address of the header portion of the SIP register message from the IP router. After changing to a public IP address, the SIP registration message is transmitted to the outgoing soft switch 700 (S402).

The outgoing soft switch 700 requests terminal registration to the registration server 300 (S403), and the registration server 300 performs a validity query for the IP address received by the application call control server 100 before confirming the registration. (S404). The application call control server 100 requests the location information corresponding to the IP address to the location information server 200 including the IP address information after checking the phone number (S405), the location information server 200 for this The location information is provided (S406). When providing location information, responses may be given by the same code in administrative districts. The application call control server 100 compares the same code information when subscribing to the subscriber and performs a final check whether the subscriber terminal is an available terminal or an unusable terminal used in a foreign country (S407). The application call control server 100 transmits information on whether the terminal is available or not available to the registration server 300 (S408), the registration server 300 determines whether to register the terminal according to this response, If it is restricted to use (S409). If the calling location of the calling terminal does not match the subscription address, some services may be restricted later, or the recipient may be indicated in which region.

5 is a diagram illustrating a sequence of short-range routing using source terminal location information.

For example, an emergency call of 119, 112, etc. is sent to the same representative telephone number 119, 112, but in fact, the call connection should be routed to the fire station or police station nearest to the calling terminal location. This is called near field routing. The calling terminal 10 transmits a SIP call (invite) message including its IP address information to the calling soft switch 700 in the case of the call of the call requiring short-range routing such as an emergency call (S501, S502). . The IP address information of the calling terminal 10 is delivered in the header portion of the SIP call (invite) message. As described above with reference to FIG. 4, in this case, when the calling terminal 10 has a private IP address, an IP router (not shown) passes through the header of the SIP invite message in the IP conversion apparatus 600. The private IP address of the part is replaced with the public IP address of the IP router, and then the SIP call (invite) message is transmitted to the outgoing soft switch 700 (S502).

The outgoing soft switch 700 transmits the call to the application call control server 100 in charge of the short-range routing (S503). The application call control server 100 extracts the IP address information of the originating terminal 10 from the header portion of the SIP call (invite) message, and then includes the corresponding IP address information corresponding to the IP address of the location information server 200. The location information is requested (S504), the location information server 200 provides the corresponding location information. When providing location information, a response may be given by the same code in the administrative area (S505). When the response is received with the same code, the routing information is extracted by comparing the subscription information of the calling terminal 10 owned by the own code to determine the number to be received (S506), and then the short range routing response is transmitted including the number. Transfer to the soft switch 700 (S507). Outgoing soft switch 700 is connected to the emergency call and the like (S508).

6 is a diagram illustrating a sequence for providing a calling area code to a called party by using calling terminal location information.

This figure can explain in particular the international call classification process for the prevention of voice phishing. The calling terminal 10 transmits a SIP call (invite) message including its own IP address information to the calling soft switch 700 (S601). The outgoing soft switch 700 connects the call to the incoming soft switch 800 (S602). The incoming soft switch 800 connects the call to the application call control server 100 (S603), the application call control server 100 inquires to the location information server 200 to check the origination area (S604), The location information server 200 transmits the location information mapped to the received IP address, for example, the country code and the same code, to the application call control server 100 (S605). The application call control server 100 refers to a profile of whether to give a calling area code when a caller ID (CID) is displayed to a called subscriber, and when the calling area code is set to give a calling area code, the calling area (country) Or by adding a region code) code and the like to generate a CID (S606) and forwards the call to the incoming soft switch (800) (S607). The incoming soft switch 800 transmits the call to the called terminal 20 including the CID assigned with the calling area (country or region code) code (S608). The called terminal 20 also provides a calling area code together with the number of the calling terminal 10 to allow the called party to determine whether to receive a call (S609), thereby preventing voice phishing.

On the other hand, in the case of a general domestic call, although not shown in the figure, as another embodiment, the outgoing soft switch 700 does not directly connect the call to the incoming soft switch 800, but transfers the call to the application call control server 100. And, the application call control server 100 queries the location information server 200 to check the origination area, the location information server 200 is the application call control server 100 the location information mapped to the received IP address And then, the application call control server 100 may connect the call to the incoming soft switch (800).

FIG. 7 is a diagram illustrating an additional service providing sequence using source terminal location information.

When the calling terminal 10 transmits an SIP invite message including its IP address information to the calling soft switch 700 (S701), the calling soft switch 700 is an application call control server ( 100) (S702). Application call control server 100 inquires the location information server 200 to check the origination area (S703), location information server 200 is the location information mapped to the received IP address, for example, country code and The code is transmitted to the application call control server 100 (S704). The application call control server 100 checks the subscriber profile and determines and provides additional service based on the origination area (S705 to S707). Examples of such additional services may include region-based weather using the calling region information, providing nearby restaurant information, region-based video advertisements, and the like.

FIG. 8 is a diagram illustrating a sequence for providing calling terminal area information and calling phone number information to the called party through the web using the calling terminal location information.

The same sequence as the process (S601 to S608) of Figure 6 is shown (S801 to S808), in addition, the application call control server 100 is the calling information, that is, the telephone number and calling area code of the calling terminal (10) It includes a step (S809) of transmitting the reception history information, including the information to the origination information web server 400. The calling information web server 400 allows users to easily check the receiving history information including the phone number and calling area code of the calling terminal 10 through the web (S810, S811). The called party may check the reception history information through the Internet using a general PC, or if the Internet telephone terminal 20 has an information inquiry function through a web connection, it may be confirmed through the Internet telephone terminal 20. . On the other hand, as described above with reference to Figure 6, in the case of a general domestic call, although not shown in the figure, as another embodiment the outgoing soft switch 700 does not directly connect the call to the incoming soft switch 800, The call is transmitted to the application call control server 100, the application call control server 100 queries the location information server 200 to check the origination area, the location information server 200 is mapped to the received IP address The location information is transferred to the application call control server 100, and then the application call control server 100 may connect the call to the incoming soft switch (800).
