一种对3G网络无线链路上ROHC的改进方法

摘要

ROHC is an accepted outstanding header compression scheme on wireless links nowadays,which is introduced in this paper.Through the analysis of mode transition of ROHC,we find the shortcoming of not keeping the balance of robustness and compression.So we discuss a new mode transition mechanism to improve the balance of robustness and compression efficiency and validate it with a simulative experiment.%介绍了ROHC这种目前公认应用于无线链路上较为理想的头部压缩方式.通过对其模式转换的分析,发现了其中鲁棒性与压缩效率未能兼顾的缺点,从而讨论了一种新的模式转换的改进方法,进一步提高了ROHC的鲁棒性与压缩效率的平衡性.最后,用仿真实验验证了改进方法的有效性.
