Abstract

A method of establishing a session between a first device and a second device. The session is established over a telecommunications network using an accelerated session setup technique. The method includes providing a first accelerated session setup technique and providing a second accelerated session setup technique. The method also includes establishing the session using either the first accelerated session setup technique or the second accelerated session setup technique based on a predetermined process.

Claims

1. A method of establishing a session between a first device and a second device, the session being established over a telecommunications network using an accelerated session setup technique, the method comprising:

providing a first accelerated session setup technique comprising transmitting media on an early bearer;

providing a second accelerated session setup technique comprising transmitting session preference information on the early bearer;

providing a third accelerated session setup technique comprising using a field in an H.245 message and receiving an acknowledgement from the second device; and

establishing the session using either the first accelerated session setup technique, the second accelerated session setup technique, or the third accelerated session setup technique based on a predetermined process.

2. The method of claim 1 wherein the predetermined process comprises:

attempting to establish the session using the first accelerated session setup technique; and

determining that the first accelerated session setup technique failed; and

establishing the session using the second accelerated session setup technique.

3. The method of claim 1 wherein a session establishment time associated with the first accelerated session setup technique is less than a session establishment time associated with the second accelerated session setup technique.

4. A telecommunications apparatus comprising:

a first processor adapted to attempt session establishment using a first session establishment technique comprising transmitting media on an early bearer;

a second processor adapted to attempt session establishment using a second session establishment technique comprising transmitting session preference information on the early bearer;

a third processor adapted to attempt session establishment using a third session establishment technique comprising using a field in an H.245 message and receiving an acknowledgement; and

a transmitter adapted to transmit audio and video information in accordance with a session established in whole or in part by the first processor, the second processor, or the third processor.

5. The telecommunications apparatus of claim 4 wherein the first session establishment technique further comprises transmitting media sent before a negotiation process using one or more preconfigured profiles.
