摘　　要：结合稳健报头压缩协议(ROHC)算法采用先判断错误类型、再进行上下文修复,最后开一个适当的缓冲区按序提交数据包的方案来减小接收端的弃包率,提高服务质量。实验结果验证了本方案的有效性。By using RObust Header Compression(ROHC), a scheme is proposed to reduce the packet loss in the receiver and increase the quality of service. At first, the error types are estimated, the context is recovered, and a proper buffer is opened to refer the packets ,and thus the packet-losting rate is reduced in receining end. The experimental results validate this scheme.
