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;

providing a second accelerated session setup technique; and

establishing the session using either the first accelerated session setup technique or the second 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 speed associated with the second accelerated session setup technique.

5. The method of claim 1 further comprising providing a third accelerated session setup technique, wherein the third accelerated session setup technique comprises receiving an acknowledgement from the second device.

6. The method of claim 5 wherein the first accelerated session setup technique comprises transmitting media on an early bearer, the second accelerated session setup technique comprises transmitting session preference information on the early bearer, and the third accelerated session setup technique comprises a field in an H.245 message.

4. (canceled)

7-9. -9. (canceled)

10. A telecommunications apparatus comprising:

a first processor adapted to attempt session establishment using one or more preconfigured profiles and one or more explicit parameters;

a second processor adapted to attempt session establishment using a field in an H.245 message; 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 or the second processor.

11. The telecommunications apparatus of claim 10 wherein the first processor uses a method with media sent before a negotiation process using one or more preconfigured profiles.

12. The telecommunications apparatus of claim 11 wherein the second processor uses the field in the H.245 message.

13-18. -18. (canceled)

19. A method of establishing a session between a first terminal and a second terminal communicating through a telecommunications network, the method comprising:

performing a first session setup technique;

determining a first portion of a set of desired session characteristics;

performing a second session setup technique; and

determining a second portion of the set of desired session characteristics.

20. The method of claim 19 wherein the first portion of the set of desired session characteristics comprises a multiplexer level.

21. The method of claim 19 wherein the second portion of the set of desired session characteristics comprises a media channel.

22-38. -38. (canceled)
