A method and apparatus for determining session parameters for a communication session between a first terminal (A) and a second terminal (B). At least the first terminal has stored at least one default set of session parameters. An identifier ( 404 ) corresponding to a proposed default set of session parameters is sent from the first terminal to the second terminal. Then, it is determined whether the second terminal accepts the proposed default set of session parameters or not. If accepted ( 406 ), the proposed default set of session parameters is retrieved in order to execute the session ( 408 ). Otherwise, the terminals fall back to a regular session setup procedure. In this way, delays and bandwidth consumption can be substantially reduced by using a minimum of messaging between the two terminals. |
