Abstract

Adaptive redundancy is implemented (either switched on or off) for a voice over internet protocol (VoIP) packet connection by a basic two step approach. A first step of adaptive redundancy implementation involves monitoring relevant sources or indicators to determine when the need for redundancy (e.g., redundancy coding) may arise. A second step of adaptive redundancy implementation involves the triggering of redundancy implementation events when the monitored sources reach or obtain certain threshold value(s) (threshold). The first and second steps of redundancy implementation can be repeated as needed. Scenarios of adaptive redundancy implementation include both network-initiated implementations (e.g., implementations initiated by a radio access network (RAN)) and mobile-initiated implementations (e.g., implementations initiated by a wireless station).
