Method And Apparatus For Establishing A Communication Session Between Two Terminals
First Claim
1. A method of establishing a requested communication session between a calling terminal and a called terminal over a given physical channel, wherein the session requires the determination of session parameters before the session can be executed, characterised by the following steps:
- determining, by means of at least one available session key, whether any session parameters for a previous session between the terminals have been stored in the terminals, and if so retrieving the stored session parameters in each of the terminals, such that the requested session can be executed based on the retrieved session parameters.

Abstract
A method and apparatus for establishing a requested communication session between two terminals (A, B) over a given physical channel, wherein the session requires the determination of session parameters before the session can be executed. It is determined (402) by means of at least one session key, whether any session parameters for a previous session between the terminals have been stored in the terminals. If so, the stored session parameters are retrieved (408), such that the requested session can be executed (410) based on the retrieved session parameters. In this way, delays involved with the establishment of sessions requiring the determination of parameters, e.g. in multimedia calls, can be reduced.

17. A terminal adapted to establish a requested communication session with another terminal over a given physical channel, wherein the session requires the determination of session parameters before the session can be executed, characterised by:
-
means for determining, by means of at least one available session key, whether any session parameters for a previous session between the terminals have been stored in the terminal, and means for retrieving the stored session parameters such that the requested session can be executed based on the retrieved session parameters, provided that the other terminal also has successfully retrieved the same session parameters. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
