Abstract

PURPOSE: A call receiving system in a terminal connected to the Internet is provided to forward a call signal received in a wired and wireless telephone number to an IP(Internet Protocol) address and receive the call signal in an Internet telephone terminal. CONSTITUTION: If call request is received, an exchange of a PSTN(Public Switched Telephone Network) confirms whether it is necessary for forwarding a call. If it is necessary for forwarding the call, the exchange analyzes a call forwarding object of a received telephone number(51). If the call forwarding object is an IP address(52), the exchange performs a VoIP(Voice over Internet Protocol) reception call process(53). If the call forwarding object is a general wired and wireless telephone number, the exchange performs a general call forwarding process(54).

Description

Phone Call Receiving System through Internet Terminal}

The present invention relates to an 'incoming Internet telephony', rather than a 'telephone internet telephony' generally used in the Internet telephone or VoIP (voice over internet protocol) technology used on the Internet. The existing Internet phone is a method of making a call by connecting to a server supporting an Internet phone through the Internet from a terminal such as a PC connected to the Internet. As shown in FIG. 1, the terminal 16 connected to the Internet or the terminal 17 connected to the wireless Internet accesses the Internet telephone server 14 through the Internet network 15, and dynamically sets the IP address of the calling party with the telephone number. After mapping, the telephone number assigned by the transmission / reception unit of the public line signal can communicate with the receiving telephone users 11 and 12 through the public telephone switching network / mobile communication switching network 13. However, this method can make calls, but it has a deadly weakness that cannot be received for incoming calls. The present invention relates to a technique in which a telephone number and an IP address conversion unit are statically assigned to the Internet telephone server device 14 in advance so that users of the Internet telephone terminals 16 and 17 can receive an Internet telephone.

An object of the present invention is to provide a system for making a reception of a wired and wireless telephone call to the Internet phone terminal by converting a call signal received by a wired or wireless telephone number to an IP address.

Figure 4 is a call forwarding IP address registration procedure of the present invention

5 is a call forwarding IP address verification procedure of the present invention.

6 is a VoIP receiving telephone call procedure of the present invention

The present invention is composed of a three-step process as shown in FIG.

The first wired internet user or wireless internet user registers the user authentication (21, 22 in Fig. 2):

Enter the necessary items for authentication such as name, social security number, password, phone number to be received, mobile phone number to be received, and the like, as shown in FIG. Receive and register. At this time, the server generates an authentication key and stores the authentication key in the authentication key store.

Steps for automatically setting a call reception signal at the wireless Internet terminal (23, 24 of FIG. 2):

This step can be activated automatically upon initialization of the operating system of the terminal or can be executed manually by the user. As shown in FIG. 4, when a user enters a password for a call forwarding request and requests user authentication 41, the server performs user authentication processing 42. After the user authentication is confirmed, the terminal inputs a wired / wireless telephone number to be forwarded to and then automatically inputs a fixed IP address or a variable IP address in the terminal, requesting to start forwarding to the IP address for the wired / wireless telephone (43). After receiving the data from the server, the transfer request of the call forwarding IP address is registered to the exchange of the telephone exchange network (44), and the exchange registers the IP address call forwarding to the corresponding telephone number. (45)

Receiving a telephone signal automatically and a telephone call step in the wireless Internet terminal (25, 26 of FIG.

As shown in Figure 5, when a call call (Call) request from the switchboard of the telephone exchange network checks the call forwarding presence, if the call forwarding is required, the call forwarding target of the phone number received from the exchange analysis (51) If the target is the IP address 52, the VoIP incoming call processing 53 is performed. If the call forwarding target is the general wired / wireless telephone number, the general call forwarding processing 54 is performed. As shown in Fig. 6, when the VoIP call forwarding request 61 is received at the exchange, the VoIP server receives a VoIP call receiving process 62. In this process, the server sends a call reception signal to the Internet terminal and the user is recognized by the Internet terminal. It makes a sound or shows the received information on the screen, and when the user presses the call button, it handles the call like a conventional internet phone.

The present invention overcomes the transmission-oriented nature of the Internet phone, it is a system that can be easily received by the Internet phone. Its application has been able to overcome the limitations of Internet telephony, which had been half the function, and promote the further development of the Internet telephony system.

Claims (2)

Wired / wireless network (PSTN network) or wireless telephone network (PSTN network) to receive and receive calls from wired / wireless telephones from PCs, PCs, PDAs, mobile phones, and Internet phones connected to the Internet or wireless Internet. CDMA network) to set up IP address instead of wired / wireless telephone number when performing call forwarding service. 2. The method of claim 1, further comprising: registering user authentication for call forwarding of an IP address at a terminal connected to the Internet or a wireless Internet, and storing an authentication key for user authentication at an Internet telephone server; The method according to claim 1, wherein the terminal requests user authentication for receiving a forwarded VoIP call, performs user authentication on the Internet telephone server, and also forwards the call forwarding telephone number and the target fixed IP address to the Internet telephone server. Requesting registration of an IP address, requesting IP address forwarding registration from the Internet telephone server to the exchange, and registering the IP address instead of a general wired / wireless telephone number for the forwarding; The call request received from the switchboard needs to be forwarded, and if the destination is an IP address, the switch makes a VoIP reception request from the switch to the Internet telephone server, and the Internet telephone server notifies the terminal of the call request. A method for making a telephone call with a terminal connected to the Internet by using a wired or wireless telephone including a step of receiving a call when the user designates a call reception on the terminal.
