Method to set up a voice over internet protocol communication
First Claim
1. A method to set up a voice over Internet Protocol communication between a mobile terminal (MT) and a second device (T2), said voice over Internet Protocol communication comprises an air interface between said mobile terminal (MT) and a base station (BS) being coupled via an access network and an Internet Protocol network to said second device (T2), characterized in that said method comprises a step of determining, according to predefined rules and conditions, during call set-up appropriate values for a plurality of parameters which are characterizing said voice over Internet Protocol communication in order to realize a desired trade-off between a predefined user quality of said voice over Internet Protocol communication and a predefined bandwidth efficiency.

Abstract
The invention concerns a method to set up a voice over Internet Protocol communication between a mobile terminal (MT) and a second device (T2) whereby the voice over Internet Protocol communication comprises an air interface between the mobile terminal (MT) and a base station (BS) which is coupled via an access network and an Internet Protocol network to the second device (T2). The method comprises a step of determining, according to predefined rules and conditions, during call set-up appropriate values for a plurality of parameters which are characterizing the voice over Internet Protocol communication in order to realize a desired trade-off between a predefined user quality of said voice over Internet Protocol communication and a predefined bandwidth efficiency.
