随着信息网络技术的快速发展,人们不再满足于使用固定终端或单个移动终端连接到互联网络上,而是希望移动网络以一种相对稳定和可靠的形式,从Internet上运动地获取信息,而采用卫星移动通信网来向这些移动平台提供对地面网络连接的延伸是一种比较经济、可行的解决方案。以该方案为研究背景,探讨了网络移动条件下的移动IP实现方法,分析了卫星移动通信与网络移动结合所产生的问题以及网络移动对隧道封装协议的影响,并就上述问题初步给出了改进策略。
As the fast development of the information network technology, people are not satisfied to get access to the internet by using the fixed terminal or the single mobile terminal, they hope to acquire the information by the mobile network in a stable and credible way, and it's a relatively economical, feasible project to provide terrestrial network extension by using the mobile platform with the mobile satellite communication network. Under the research background of the project, this paper discusses the method of realization to Mobile IP under the condition of NEMO, analyzes the problems owing to the combination of mobile satellite communication and NEMO and the effect of whieh NEMO works on the Tunnel Encapsulation protocols, and puts forward the improvement tactics to the above problems.
