Abstract

PURPOSE: A call forwarding service method in an Internet phone system is provided to automatically request a call setup to a callee's PC when a caller requests the call setup but the callee's PC is not available for accepting the call setup. CONSTITUTION: A caller attempts a connection to a gatekeeper through a PC(S200). The gatekeeper compares an ID and a password of the caller's PC with a pre-set ID and password, and if they are identical, the gatekeeper authenticates the user(S202). When the caller requests the gatekeeper to set up a call setup to a callee's PC, the gatekeeper transmits call setup information to the callee's PC(S204). The callee's PC transmits current status information to the gatekeeper and the gatekeeper transmits the status information to the caller's PC(S206). If the callee is not available for accepting the caller's call setup, the caller's PC requests the gatekeeper to automatically set up a call to a callee's phone(S208). The gatekeeper selects the gateway closest to the callee's phone and informs the caller's PC of an IP address of the gateway(S210,S212). When the caller requests a call setup, the gateway converts a requested call setup signal and requests a call setup from the callee's phone(S214,S216). When the callee's phone accepts the call setup request, the accept information is transmitted to the caller's PC to complete a call setup so that the caller and the callee can make a voice communication(S218,S220).

That is, the call may be connected in the form of the caller's fish and the callee's voice, or the call may be connected in the form of the caller's fish and the caller's phone. At this time, the caller requests a call setup to the caller's fish through the caller's fish by the fish-to-fish method, and normal call is not possible unless the caller's call accepts the call setting request. Then, the caller was inconvenient to wait for the called party to accept the call establishment request or to request the call establishment again to the called party by the fish-to-phone method. On the contrary, the caller requests the call setup to the called party's phone through the caller's fish by the fish-to-phone method, and normal call is impossible unless the caller's phone accepts the call setup request. Then, the caller was inconvenient to wait for the called party to accept the call establishment request or to request the call establishment again to the called party by the fish-to-fish method.

Accordingly, the present invention has been made to solve the above problems, in the case of a caller requests a call setup to the recipient fish or phone using his or her authenticated fish in the Internet-to-fish or fish-to-phone Internet phone system It is an object of the present invention to provide a call forwarding service method in an Internet telephone system that can automatically request a call establishment from a called party phone or a fish if a callee or phone cannot accept call setup.

In order to achieve the above object, according to the present invention, a caller uses a fish and a caller uses a fish or phone to provide a call forwarding service in an internet telephony or fish-to-phone Internet telephone system. A first step of authenticating the caller's fish that attempts to access to use an internet-to-fish Internet service in a; A second step of, when the gatekeeper receives a call setup request from the authenticated originator fish to a called party fish, transmitting the received call setup request information to the called party fish; And a third step of automatically requesting the caller to set up a call to a called party at the caller's fish when the caller's fish do not accept the call establishment request. It is characterized by operating so that possible.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is a conceptual diagram of a preferred Internet telephone system according to the present invention, in which a sender uses a multimedia fish 100 capable of using the Internet and a called party uses a multimedia fish 160 capable of using the Internet, or The caller represents a fish-to-phone Internet telephone system using a multimedia PC 100 and the called party uses a general telephone (Phone: 150). The main standard of such Internet telephony system is based on H.323 defined in ITU-T SG15. The H.323 standard can be divided into call control function and voice transmission function.

On the other hand, the PC-to-PC method is the caller fish 100 and the recipient fish 160 is connected to the Internet network 110, the PC-to-phone method is connected to the caller fish 100 and public telephone network (Internet network 110) The called party phone 150 connected to 140 is connected through the gateway 130. In addition, the Internet telephone system includes a gatekeeper 120 connected to the Internet network 110 separately.

The gatekeeper 120 authenticates the caller fish 100 attempting to access the caller to the Internet voice call, and between the authenticated caller fish 100 and the called phone 150, or between the caller fish 100 and the called party It relays between the fish 160 to enable a voice call. In addition, when making a voice call using the fish-to-phone method, call charge data to be charged to the called party phone 150 is generated. The gateway 130 may convert a signal input through the internet network 110 into a form that can be transmitted from the public telephone network 140 or transmit a signal input through the public telephone network 140 from the internet network 110. Convert it to the present form.

2 is a flowchart illustrating a process of the call forwarding to the called party's phone due to the call setup impossibility in the called party's fish when the call setting request is made by the called party's fish according to the present invention.

In order to practice the present invention, it is assumed that the caller uses the Internet telephone in the form of a fish and the called party subscribes to the Internet telephone service in order to use the Internet telephone in the form of a fish or a phone.

Referring to the drawings, first, the caller attempts to connect to the gatekeeper 120 through the caller fish 100 through the caller fish 100 to use the Internet phone service (S200). Then, the gatekeeper 120 compares whether the ID and password inputted from the caller fish 100 match with the previously stored ID and password of the caller, and authenticates that the gatekeeper 120 can be used (S202). Subsequently, when the caller requests the gatekeeper 120 to set up a call to the called party fish 160 using the authenticated caller fish 100, the gatekeeper 120 receives the requested call setting information from the called party fish 160. In step S204. At this time, the recipient fish 160 transmits the current state information to the gatekeeper 120, and the gatekeeper 120 transmits the received state information to the caller fish 100 (S206).

Although not mentioned in the drawing, when the callee requests the call setup request from the receiver 160, the call information is completed when the call setup is completed and the caller and the caller can make a voice call in a PC-to-PC manner. However, in the state information, the called party is busy (Busy) with another person through his fish 160, or the called person is no answer (No answer), or the recipient fish 160 is not authenticated ( Not login) automatically requests the caller to establish the call to the called party phone 150 from the caller fish 100 (S208). That is, when the above state information is input, the process is automatically switched to the call by the preset interrupt routine. Then, the gatekeeper 120 selects the gateway 130 closest to the called party's phone 150 and informs the caller's IP 100 of the gateway 130 (S210, S212).

Next, when the caller requests a call setup to the destination phone 150 from the gateway 130 having the IP address obtained from the caller fish 100, the gateway 130 converts the requested call setup signal to the called party. The phone 150 requests a call setup (S214, S216). Subsequently, when the caller's phone 150 accepts the call setup request, the acceptance information is transmitted to the caller's fish 100 and the call setup is completed, thereby allowing the caller and the caller to make a voice call using the P2P method (S218, S220). ).

3 is a flowchart illustrating a process of the call forwarding to the caller's PC due to the impossibility of call establishment in the caller's phone when the call setup request is made to the caller's phone through the caller's fish according to the present invention.

Referring to the drawings, the caller first attempts to connect to the gatekeeper 120 to the gatekeeper 120 through the caller fish 100 to use the Internet phone service (S300). Then, the gatekeeper 120 compares whether the ID and password inputted from the caller fish 100 match with the previously stored ID and password of the caller, and authenticates that the gatekeeper 120 can use the same when it matches (S302). Subsequently, when the caller requests the gatekeeper 120 to set up the call to the called party phone 150 using the authenticated caller fish 100, the gatekeeper 120 closes the gateway 130 closest to the called party phone 150. Select () to inform the caller fish 100 of the IP address of the gateway 130 (S304, S306, S308).

Next, when the caller requests a call setup to the called party phone 150 from the gateway 130 having the IP address obtained from the caller fish 100, the gateway 130 converts the requested call setup signal to the called party phone. In step 150, call setup is requested (S310, S312). At this time, the called party phone 150 transmits the current state information to the gatekeeper 120, the gatekeeper 120 transmits the received state information to the caller fish (100) (S314).

Although not mentioned in the drawing, when the caller requests the call setup request from the called party 150, the call information is completed when the call setup is completed and the caller and the called party can make a voice call using the PC-to-phone method. However, when the called party is busy (Busy) with the other person through his phone (150) or when the called person is empty and does not answer (No answer) in the state information, the caller fish 100 in the gatekeeper The call setup request is automatically made to the called party fish 160 at 120, and the gatekeeper 120 transmits the requested call setting information to the called party fish 160 at step S316. That is, when the above state information is input, the process is automatically switched to the call by the preset interrupt routine.

Then, when the caller's fish 160 accepts the call setup request, the acceptance information is transmitted to the caller's fish 100 so that the call setting is completed, and the caller and the caller can make a voice call in a fish-to-fish manner (S318). S320).

According to the present invention, when a caller requests a call setup to a caller's PC using his or her own authenticated PC, the caller's PC can automatically accept the call setup. By requesting the call setup from the called party's phone, the Internet voice call of the fish-to-phone method can be realized. In addition, when the caller requests a call setup from the called party's phone using his own authenticated fish, the caller automatically requests the call setup from the called party's fish when the caller's phone cannot accept the call setup. Voice call can be realized. Therefore, the Internet telephone user can use a convenient internet telephone service.
