Abstract

A variety of conversational multimedia services have been developed and provided for a FMC (fixed mobile convergence) environment, which contains a variety of wireless networks, such as 1x EV-DO (1x EVolution Data Only), WiMAX (worldwide interoperability for microwave access), WiFi (wireless fidelity) and combinations. The bandwidths of several wireless networks are asymmetric and restricted. For example, for the asymmetric link, 1x EV-DO specifies the peak rates for downlink and uplink as 2.4 Mbit/s and 153 Kbit/s. A header compression scheme for the transmitted packets of conversational multimedia signals is an effective solution for these scarce links, especially in the IPv6 environment. However, ways to improve the performance of the header compression scheme have not been thoroughly evaluated quantitatively considering the quality of conversational multimedia services over the asymmetric wireless links where the transmission characteristics of the up and down links are quite different. This paper presents the results of a study that examined ways to improve the performance of the header compression scheme based on control of the header compression parameters considering speech quality over the asymmetric wireless link. The paper also presents experimental verifications of the efficiency of our proposal using a practical implementation

基于客观语音质量测量的非对称无线链路报头压缩性能增强

各种对话式多媒体服务已经开发出来，并提供给FMC(固定移动融合)环境，其中包含各种无线网络，如1x EV-DO(仅1x EVolution数据)、WiMAX(微波访问的全球互操作性)、WiFi(无线保真度)和组合。几种无线网络的带宽是不对称的和受限的。例如，对于非对称链路，1x EV-DO规定下行速率峰值为2.4 Mbit/s，上行速率峰值为153 Kbit/s。一种对话型多媒体信号传输包的报头压缩方案是解决这些链路稀缺问题的有效方法，特别是在IPv6环境下。然而，考虑到非对称无线链路上的会话多媒体服务的质量，提高报头压缩方案性能的方法还没有得到彻底的定量评估，其中上行和下行链路的传输特性有很大的不同。本文介绍了一项研究的结果，研究了在考虑非对称无线链路上语音质量的情况下，基于对报头压缩参数的控制来提高报头压缩方案性能的方法。本文还通过一个实际实现对我们的建议的有效性进行了实验验证
