Patent ID: 7787377

Claim:
A method of operating a telecommunications network comprising: monitoring an indicator for a flow of packets, the packets carrying voice and/or audio over a packet switched connection involving a wireless station, for determining a need for redundancy of at least some packet content for the packets; in accordance with the monitoring, selecting and implementing one of plural redundancy modes as an implemented redundancy mode, the plural redundancy modes including a full redundancy mode, a partial redundancy mode, and a selective redundancy mode; wherein in each of the plural redundancy modes contents of certain mode-specific packets are, upon initially transmission in the packet switched connection, redundantly transmitted in two consecutive packets, the certain mode-specific packets being: all packets for the full redundancy mode; packets that hold onset voice frames for the selective redundancy mode; and packets that have parameters that need to be duplicated for the partial redundancy mode; adaptively switching among the plural redundancy modes and a no redundancy mode in accordance with the monitoring; and wherein outgoing packets are coded in accordance with the implemented redundancy mode until a switching to another mode, the switching also being in accordance with the monitoring.
