A highly reliable gateway device for improving the performance of communications utilizing the transport layer connection provided via a radio network, by setting up the transport layer connection between a wire terminal and a radio terminal in a form suitable for an application, or by enabling a control of the transport layer connection according to the radio communication state between the radio terminal and a base station, without changing implementation of the transport layer of a terminal connected to a wire network, is disclosed. The gateway device determines whether or not to carry out a set up of a connection in divided forms according to an information content of a packet that contains a transport layer protocol data unit requesting a set up of the transport layer connection between the radio terminal of the radio network and the wire terminal of the wire network.
A gateway device for relay connecting a radio network and a wire network, comprising:
A gateway device in a communication network in which a plurality of gateway devices connected to respectively different radio networks are inter-connected through a wire network, the gateway device comprising:
A gateway control method in a communication network in which a plurality of gateway devices connected to respectively different radio networks are inter-connected through a wire network, where each gateway device has a connection set up unit for setting up a transport layer connection between radio terminals of the radio network in divided forms of first and second connections in a transport layer protocol for communications with the radio network, or a transport layer connection between a radio terminal of the radio network and a wire terminal of the wire network in divided forms of a first connection in a transport layer protocol for communication with the radio network and a second connection in a transport layer protocol for communications with the wire network, the method comprising the steps of:
