Method for the adaptation of comfort noise generation parameters

A method for the adaptation of comfort noise generation parameters which are provided for generating a background noise signal in a telecommunications system including a packet-oriented telecommunications network and first and second communications devices operatively connected to the packet-oriented telecommunications network, the method comprising:

• generating the comfort noise generation parameters by the first communications device;
• inserting the comfort noise generation parameters in at least one silence insertion descriptor transmission frame;
• transmitting the silence insertion descriptor transmission frame toward the second communications device via the packet-oriented telecommunications network by the first communications device;
• receiving the silence insertion descriptor transmission frame having the comfort noise generation parameters by the second communications device;
• and
• comparing the transmitted comfort noise generation parameters with a comfort noise generation parameter format,
• wherein if the comparison shows a deviation the transmitted comfort noise generation parameters are adapted to the comfort noise generation parameter format by removing an individual comfort noise generation parameter and/or,
• wherein if the comparison shows missing, errored, or incompatible transmitted comfort noise generation parameters, the transmitted comfort noise generation parameters are adapted to the comfort noise generation parameter format by replacing individual comfort noise generation parameters with a comfort noise generation parameter set.
