ABSTRACT:
A TCP/IP (Transmission Control Protocol/Internet Protocol) communication system includes a provider side unit to which a first communication terminal is operatively connected through a line network; and a mobile switching controller to which a second communication terminal is operatively connected. The mobile switching controller includes first and second termination circuits, a detecting unit, a line signal circuit and a switch. The first termination circuit is connected between the mobile switching controller and the provider side unit to transfer data on a first channel from the second communication terminal to the first communication terminal. The second termination circuit is connected between the mobile switching controller and the provider side unit to transfer data on a second channel from the first communication terminal to the second communication terminal. The detecting unit is connected to the first and second termination circuits, and detects an IP address and a first message from first data as the data transmitted from one of the first and second communication terminal, and a second message from second data as the data transmitted from the other. The first message is detected when the first data has a finish flag and an acknowledgement flag which are set, and the second message is detected from the second data responding to the first data and having an acknowledgement flag which is set. The line signal circuit converts the IP address into a terminal number. The switch releases the first and second channels associated with the terminal number.
