Abstract:
A method for establishing a communication session between at least a first terminal in a first network and a second terminal in a second network, where said first network and said second network are members of a set of networks that employ differing transmission standards, said set of networks including a circuit switched network, a connectionless packet switched network and a connection-oriented packet switched network, said method comprising the steps of:receiving a call set-up request from said first terminal in accordance with a call set-up protocol associated with said first network, said call set-up request specifying said second terminal; ascertaining said second network and identifying type of said second network, the type being one of the types of networks that belong to said set of networks; translating said call set-up request into a call set-up signal in conformance with a protocol associated with said second network; translating information received from said first terminal from a first encoding format to a second encoding format; transmitting said information in the second encoding format to the second terminal; storing control information relating to the first and second terminals, said control information including an identification of the first and second terminals participating in the communication session.
