First Claim
Patent Images
1. A method for establishing a communications session by a terminal operating in a wireless communications system, the method comprising:
- sending an invitation message from the terminal wherein the invitation message comprises a parameter defining a maximum bit rate of a voice codec;
receiving a confirmation message by the terminal in response to the invitation message wherein the confirmation message comprises a retransmission of the parameter defining the maximum bit rate of the voice codec; and
transmitting voice traffic from the terminal at the maximum bit rate defined by the parameter wherein the maximum bit rate is varied according to conditions of the wireless communications system.

Abstract
In session data and a method for establishing a session in a synchronous wireless communication system in accordance with the present invention, by additionally defining a maximum bit rate parameter of the EVRC such that the maximum rate can be varied according to circumstances and conditions of a wireless network, the capacity of the wireless network is expanded and therefore more efficiently used. Services can be flexibly implemented according to the circumstances and conditions of the wireless network by using the maximum bit rate parameter for increasing or decreasing the bandwidth of the wireless network.

7. A method for establishing a communication session of a wireless communications system between a first terminal and a second terminal, wherein the first terminal belongs to a first network and the second terminal belongs to a second network, the method comprising:
-
sending a first invitation message from the first terminal wherein the first invitation message comprises a first parameter defining a first maximum bit rate of a voice codec for transmitting voice traffic from the first terminal;
receiving a second invitation message by the second terminal wherein the second invitation message comprises a second parameter defining a second maximum bit rate of the voice codec for transmitting voice traffic;
sending a first confirmation message from the second terminal wherein the first confirmation message comprises the second parameter defining the maximum bit rate of a voice codec;
receiving a second confirmation message by the first terminal wherein the second confirmation message comprises the first parameter defining the maximum bit rate of a voice codec;
transmitting voice traffic from the first terminal at the first maximum bit rate; and
receiving voice traffic by the second terminal at the second maximum bit rate. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A wireless communications terminal comprising:
a means for establishing a communications session between a first terminal and a second terminal wherein the first terminal is in a first network and the second terminal is in a second network, and wherein the means for establishing a communications session further comprises;
a first invitation message sent from the first terminal wherein the first invitation message comprises a first parameter defining a first maximum bit rate of a voice codec for transmitting voice traffic from the first terminal;
a second invitation message received by the second terminal wherein the second invitation message comprises a second parameter defining a second maximum bit rate of the voice codec for transmitting voice traffic;
a first confirmation message sent from the second terminal wherein the first confirmation message comprises the second parameter defining the maximum bit rate of a voice codec;
a second confirmation message received by the first terminal wherein the second confirmation message comprises the first parameter defining the maximum bit rate of a voice codec;
transmitting voice traffic from the first terminal at the first maximum bit rate; and
receiving, voice traffic by the second terminal at the second maximum bit rate. - View Dependent Claims (15, 16, 17, 18, 19, 20)
