Abstract
During communication over the network, periods of silence may exist. During these periods, the system may enable a user at a user terminal to define characteristics of a comfort signal. The system may monitor transmission to detect periods of silence. The system may adapt the monitored transmission by adding the defined comfort signal during the periods of silence, as background noise, or during periods of silence and as background noise.
Claims11
A method comprising:
- activating, based on a user selection, silence suppression for a transmission over a communications network;
- receiving, from a user, a selection of a type of comfort signal to be added to the transmission, the comfort signal having a frequency between approximately 330 Hz and 3.4 KHz representing a specific noise color defined by a combination of eight bits of data;
- receiving, from the user, definitions of characteristics of the comfort signal to be added to the transmission, the characteristics including a length, pattern, and intensity of the comfort signal;
- monitoring the transmission to detect packets of silence;
- and
- adapting the transmission by adding the comfort signal to the transmission as background noise, during periods of silence, or during periods of silence and as background noise, the added comfort signal being modified according to the user defined characteristics of the comfort signal.

A system comprising:
- a network providing telephony services;
- a calling device, coupled to the network, configured to interface a user with the network;
- and
- a comfort center coupled to either the calling device or the network, wherein the comfort center and calling device enable the user to:
- activate, based on a user selection, silence suppression for a transmission over a communications network;
- receive, from the user, a selection of a type of comfort signal to be added to the transmission, the comfort signal having a frequency between approximately 330 Hz and 3.4 KHz representing a specific noise color defined by a combination of eight bits of data;
- receive, from the user, definitions of characteristics of the comfort signal to be added to the transmission, the characteristics including a length, pattern, and intensity of the comfort signal;
- monitor the transmission to detect packets of silence;
- and
- adapt the transmission by adding the comfort signal to the transmission during periods of silence, as background noise, or during periods of silence and as background noise, the added comfort signal being modified according to the user defined characteristics of the comfort signal.
