摘要：

PoC is a group communication service using VoIP technology based on 3G cellular network packet domain carrier. ROHC can complete the header compression in PS domain of 3G network, which can improve the efficiency of wireless transmission. This paper analyzes the working principle and the operation modes of ROHC, designs the processing of the compressor and decompressor. Simultaneity an improved algorithm applied to the U mode is presented against PoC service features, with great benefits on cost and quality of service (QoS).
