Patent ID: 7558247

Claim:
A method implemented in a computing system for processing data packets transmitted over a single radio bearer service in a mobile communication network, the method comprising: receiving, in a mobile communication terminal, data transmitted in a single packet stream; determining a characteristic of data transmitted over the single packet stream; and splitting contents of data packets communicated over a single stream into at least two different sub-streams according to the characteristic of each content, wherein contents having different characteristics are transmitted separately in each sub-stream according to a delay or error rate requirement appropriate for the respective content, wherein first content having a first characteristic is transmitted over a first sub-stream with a first transmission priority and second content having a second characteristic is transmitted over a second sub-stream with a second transmission priority; wherein the characteristic of each packet identifies a packet type, wherein the first sub-stream is for real-time transport protocol (RTP) packets and the second sub-stream is for real-time transport control protocol (RTCP) packets, wherein the RTP packets are transmitted through an unacknowledged mode (UM) RLC entity and the RTCP packets are transmitted through an acknowledged mode (AM) RLC entity, and wherein the first transmission priority has a higher priority compared with the second transmission priority such that the RTP packets transmitted through the UM RLC are processed at a higher priority than the RTCP packets transmitted through the AM RLC entity.
