Abstract
A method and system for increasing the efficiency of providing bandwidth for voice traffic to a data provider via asynchronous communication mediums is provided. This is generally accomplished by not transmitting any data during the silence periods and playing out background noise (i.e., comfort noise) at the other end, to obtain significant bandwidth savings.
Claims1
A method for suppressing silence in bidirectional communications between a centralized node and a plurality of local nodes in an asynchronous network environment, comprising the steps of:
- detecting a silent period in an upstream channel, said upstream channel transmitting data from a local node;
- and
- deactivating unsolicited grant service and not activating request polling in response to said detecting a silent period.
Dependencies are inferred from the claim text.
