Method and means for encoding background noise information

A method for the generation of Silence Insertion Description (“SID”) frames for a discontinuous transmission of background noise parameters via a transmission network, the method comprising:

• producing first narrowband SID information of background noise for inclusion into a first SID frame as a first component of the first SID frame via at least one encoder device communicatively connected to the transmission network;
• producing second wideband SID information of the background noise for inclusion into the first SID frame as a second component of the first SID frame via the at least one encoder device;
• producing third SID information of the background noise for inclusion into the first SID frame as a third component of the first SID frame via the at least one encoder device;
• forming the first SID frame to include the first component, the second component and the third component, the first, second and third components being in separate areas of the formed first SID frame;
• analyzing, via the at least one encoder device, the background noise based on at least one of energy and frequency distribution during a phase that precedes transmission of the first SID frame;
• transmitting the first SID frame via the transmission network in response to detecting one of:
• (i) a change in a wideband component of the background noise is equal to or exceeds a predetermined threshold,
• (ii) an occurrence indicating that an update to the narrowband SID information is to be sent;
• and
• receiving, by a receiver side, the first SID frame;
• and
• determining, by the receiver side, whether comfort noise should be generated based on the first component of the first SID frame or whether comfort noise should be generated based on the second component of the first SID frame or whether comfort noise should be generated based on the third component of the first SID frame.
