互联网规约在移动电话网中的应用

Application of Internet Protocal on Wireless Network

简述无线ＶｏｉｃｅｏｖｅｒＩＰ的两种方案，讨论在话音质量上对分组数据间隔和蜂窝区交接的要求，以及在ＴＤＭＡ和ＣＤＭＡ中的使用。最后介绍新一代移动网设计时应考虑ＶｏｉｃｅｏｖｅｒＩＰ和ＭｕｌｔｉｍｅｄｉａｏｖｅｒＩＰ的建议。

The paper begins with explaining the effect of Voice over IP and Multimedia over IP in wireline network on their application to wireless network.Then,it discusses the two models of wireless Voice over IP,the quality requirement on packet based voice and in case of handoff across cell boundary,and the operation on two different air interfaces, TDMA and CDMA.Finally,the paper enumerates the implications for new generation of wireless network design as suggested by Bell Labs.
