Research and Implementation of ROHC for PoC Service Based on TD-SCDMA Network
PoC is a half-duplex PTT service using VoIP technology based on cellular network packet domain carrying.ROHC is used to implement the header compression in PS domain,which can improve the transmission efficiency of the air interface.This paper describes the working principle and the modes of operation about ROHC,designs the realization processing of the compressor and decompressor.Simultaneity an improved algorithm applied to the U mode is brought forward against PoC service features,and can improve the robustness of ROHC and the QoS of PoC session.
