Variable communication bandwidth for providing automatic call back and call hold
First Claim
1. A method for providing telecommunication features on an existing telecommunication call by telecommunication terminals and the telecommunication call is established through a telecommunication system over a telecommunication call path between a calling telecommunication terminal and a called telecommunication terminal, the method comprising the steps of:
- detecting initiation of a first portion of an automatic call back feature on the existing telecommunication call;
adjusting the telecommunication bandwidth of the call to an amount to implement the first portion of the automatic call back feature by transmission of a first message for changing the telecommunication bandwidth through out the whole telecommunication call path;
detecting initiation of a second portion of the automatic call back feature; and
adusting the telecommunication bandwidth of the call to an amount to implement the second portion of the automatic call back feature by transmission of a second message for changing the telecommunication bandwidth through out the whole telecommunication call path.

Abstract
Automatically reducing communication bandwidth to coincide with the state of a communication call by a communication terminal. If a first telecommunication terminal puts a second telecommunication terminal on hold, the first telecommunication terminal transmits a transport message that reduces the bandwidth of the call to a low speed data link. When the first telecommunication terminal wishes to again be in communication with the second telecommunication terminal, a transport message is utilized to restore the communication bandwidth. If a first communication terminal calls a second communication terminal and the second communication terminal is busy, the first communication terminal reduces the bandwidth of the communication call to that of a low speed data link. When the second telecommunication terminal becomes idle, the second terminal sends a message to the first terminal indicating the idle state. The first telecommunication terminal then uses a transport message to increase the communication bandwidth to the desired amount and engages the second communication terminal in a communication call.
