版权信息   版权信息

下一代移动通信系统将是全IP移动通信系统,其移动性管理策略由移动PPP协议和移动IP协议这两个重要的支撑协议组成。而如何将Diameter技术和移动性管理技术融合实现AAA(Authentication、Authorization、Accounting)是无线IP网络中最重要和最具挑战性的问题之一。 各种不同网络的融合以及互联网本身的飞速发展,迫切需要新一代的基于IP技术的AAA。IETF AAA工作组提出的Diameter协议族将取代RADIUS成为新的AAA协议。IETF提出的移动IP协议具有广泛的应用前景,有望取代现有移动通信系统中的各种移动性管理协议,解决未来移动通信系统中的移动性管理问题。但移动IP技术也存在一些固有的缺陷,如切换中不能保证通信业务的服务质量、位置注册时延过长等。目前的研究倾向于采用一种层次型的移动性管理方法来解决这些问题,即用移动IP来支持宏移动(macro-mobility),而采用更优化的微移动(micro-mobility)协议来进行本地移动性管理。本文对移动性管理的基本原理、Diameter协议以及现有的移动性管理协议进行了详细的分析,提出了在使用移动IP解决无线IP网络中的移动性管理问题时,如何利用更为优化的微移动性管理协议来处理本地移动性等问题;

错误译文

It is the all-IP mobile communication system that will be the next generation of mobile communication system, whose mobility management is consisted of two supporting protocols :mobile PPP and mobile IP; meanwhile, mobility management is recognized as one of the most important issues and challenging in wireless IP networks.Considering the integration of different types of network and the rapid development of Internet, a new technology based on IP is urgently needed. Therefore, IETF advanced Diameter protocol which will replace Radius and become the new AAA protocol. Mobile IP, which was proposed by IETF, with its far and wide prospect in application is expected to be a promising solution in the future mobile communication systems and consequently a replacement of the various mobility management protocols in the existing mobile communication systems nowadays. But, mobile IP technology has some built-in weaknesses. For instance, it fails to guarantee the QoS (Quality of Service) of ongoing sessions in handoffs; it may cause unacceptable latency in location registration. And present researches are inclined to adopt a hierarchical mobility management approach to solve these problems, i.e. making use of the Mobile IP to support macro-mobility, and the optimized micro-mobility protocols to manage local area mobility.Based on the research existing outcomes.

修改后译文

It is the all-IP mobile communication system that will be the next generation of mobile communication system, whose mobility management policy consists of two important supporting protocols which are mobile PPP and mobile IP protocol; meanwhile, AAA(Authentication, Authorization and Accounting) which is realized by the integration of mobility management policy and Diameter technology is recognized as one of the most important issues and challenging in wireless IP networks. Considering the integration of different types of network and the rapid development of Internet itself, a new generation of AAA based on IP technology is in urgent demand. Therefore, the Diameter protocol proposed by IETF will replace Radius and become the new AAA protocol. Mobile IP protocol proposed by IETF has great prospect in application, and is expected to be a promising solution in the future mobile communication system, and consequently resulted in a replacement of the various mobility management protocols in the existing mobile communication systems. However,, mobile IP protocol technology has some built-in weaknesses. For instance, it fails to guarantee the QoS (Quality of Service) of communications service in handoffs; it may cause unacceptable latency in location registration. The existing researches are inclined to adopt a hierarchical mobility management for solving the problems, namely making use of the Mobile IP to support macro-mobility, and the optimized micro-mobility protocols to manage local area mobility. This paper has provided a detailed analysis on the basic principle of mobility management, Diameter protocol and the conventional mobility management protocol, moreover, it proposed how to employ the optimized micro-mobility protocols to manage local area mobility when solving problems in mobility management of wireless IP by Mobile IP.
