Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a method for automatically switching a call of a communication terminal, and more particularly, to a method of switching a call of a communication terminal to connect a call using the Internet.
In general, the telephone network is composed of a fixed telephone network and a wireless telephone network. In addition, there is a data communication network. Each network is interworked to enable voice communication and data communication.
When a call is attempted using a wire telephone terminal of the wire telephone network, the exchange station of the wire telephone network controls the connection with the terminal of the other party. Accordingly, when the counterpart terminal is located within the wireline telephone network, the counterpart terminal provides the connection with the counterpart terminal inside the wireline telephone network through interlocking with the exchange office itself or another exchange.
On the other hand, in order to establish a call connection with a wireless telephone network outside the wire telephone network, it is necessary to interwork the wire telephone network and the wireless telephone network. That is, when an attempt is made to make a call to a mobile communication terminal using a wire telephone terminal, a switching center of a wire telephone network connects with a wireless switching center of a wireless telephone network, and a wireless switching center finds a partner mobile communication terminal and provides connection. Accordingly, the wired telephone of the wired telephone network can communicate with the mobile communication terminal of the wireless telephone network.
Also, in case of international telephone, it is possible to make a call by interworking with a domestic fixed telephone network or a wireless telephone network and an overseas fixed telephone network or a wireless telephone network. When an attempt is made to make an international call to a domestic mobile communication terminal, the counterpart country code is identified according to the counterpart telephone number, and the counterpart of the radio telephone establishes a connection with the counterpart of the foreign country. The foreign exchange can provide a connection to the other's wired terminal or mobile communication terminal. As a result, international calls can be made.
Recently, attempts have been made to provide voice calls using the Internet. This is a result of a widespread use of the Internet-based telephone call technology and a significant improvement in the voice call quality even when using the Internet.
In order to make a voice call using the Internet, an IP address must be allocated to the Internet service provider (ISP) using a computer. After that, you can connect to the other party by running internet phone program on your computer.
Another way to use the Internet is to use an Internet phone. An Internet telephone having an IP address allocated from an Internet service provider is used, and the Internet telephone encapsulates voice information and treats it as data in the Internet network and transmits the encapsulated voice information. When connecting to a wired or wireless telephone network, a gateway is provided to convert the voice information. Accordingly, it is possible to provide a voice call with a wired telephone or a mobile communication terminal. This is characterized in that it is convenient to use because it is similar in shape and use method to a conventional telephone.
Both of these methods require a gateway for converting a protocol for coupling with a wired communication network or a wireless communication network, and in particular, provide a mapping table of addresses (IP address and telephone number) for interworking between networks A gatekeeper is required.
However, even when interworking between networks is performed as described above, there is a problem that a function of a general wired telephone or a mobile communication terminal using a single terminal and a function of making a call via the Internet network are not provided do. Further, there is a problem that the call can not be switched so that the ordinary call can use the Internet network.

First, the phone number of the counterpart terminal can be confirmed by extracting the counterpart phone number using the call signal transmitted from the counterpart terminal (S410). The identified phone number of the other party's terminal may be used at the time of originating at a later stage.
Next, in the case where the communication terminal transmits a call signal to the counterpart terminal using the Internet network (S450), when the communication terminal is a communication terminal supporting the voiceover Internet protocol, the voiceover Internet protocol of the terminal is used (Step S451). If the communication terminal is a communication terminal that does not support the voice-over Internet protocol, it may be a step S452 of sending a call signal via the voice-over internet protocol server have.
In step S451, a call signal using the voice over internet protocol of the terminal is encapsulated as voice data through VoIP and transmitted to the Internet through the voice information of the communication terminal.
For example, in order to establish a call connection from a communication terminal to a correspondent terminal, a call signal is transmitted using a phone number of the counterpart terminal. At this time, the voice information is encapsulated by VoIP and is handled as data. Then, the signal is connected to the switching network through the switching center, and then to the Internet network in the switching network. In this case, since the data is treated as data, the conversion process at the gateway is omitted. Therefore, signals are transmitted using the Internet network.
In a case where a communication terminal makes a connection to a VoIP server in order to connect a call, the VoIP server sends a call signal via the voice over internet protocol server (S452) To be transmitted to the gateway. This makes it possible to make a call using the Internet network. Also, the IP address of the VoIP server may be designated by the user.
For example, in order to establish a call connection from a communication terminal to a counterpart terminal, a call signal is transmitted using the telephone number of the counterpart terminal. In addition, a signal including the IP address of the VoIP server for using the VoIP server is transmitted. The signal is connected to the switching network through the switching center and directly to the VoIP server in the switching network. In the VoIP server, it is transmitted to the gateway to use the Internet network. Therefore, signals are transmitted using the Internet network.
In addition, the use of the automatic call switching method of the communication terminal according to the present invention can be designated by the user of the communication terminal. Therefore, if the user does not want to use the automatic call switching method of the communication terminal according to the present invention, the automatic terminal switching method according to the present invention may not be used.
