Mobile IP係根據IETF所提出的繞徑協定標準，提供行動節點在不改變應用程式及IP的前提下，仍能夠漫遊於IP網路之中，此外有關學界提出更好的Cellular IP、HAWAII、TeleMIP及TIMIP … 等行動網路架構，利用區域管理特色改善Mobile IP效率不佳的缺點，這些建置在全IP網路基礎上的行動網路，具備多媒體網路通訊的優點，且核心網路具有高整合、彈性及效能的特點，未來可能被使用在第三代個人行動通訊系統中，基於如此趨勢，如何利用國軍現有龐大的網路資源，規劃出具有行動機制得核心網路，藉以提高國軍行動通訊能力，乃是當前的重要課題，因此本研究提出NLMIP行動網路架構，同樣具備Mobile IP功能及區域管理特色，主要建構在區域網路基礎上，藉由核心網路運作機制，提供使用者在IP網路下無縫隙行動通訊的能力，因此NLMIP的應用層面廣泛，例如VOIP、即時視訊、遠距監控、命令傳遞及GPS定位 … 等，提供國軍另類的數位化通訊整合平台，改善傳統先按再說(Push-to-Talk)的通訊設備的不足，開創數位化戰場新紀元，後續文中將介紹詳細的NLMIP規劃方式及運作機制，同時探討其中最佳化方法與應用層面，提供國軍未來行動通訊網路建置之參考。

Mobile IP is a router protocol standard proposed by the IETF and provides the capability of roaming in IP networks without changing any application program and IP address. Better mobile network structures had been proposed such as Cellular IP, HAWAII, TeleMIP, and TIMIP, etc. They utilize the characteristic of local management to improve the efficiency of Mobile IP. These mobile networks are built upon All-IP networks and possess merits of multimedia communication. Based on the advantage of high integration, flexibility, and performance, they are possibly adopted in the third generation mobile communication system. Therefore, utilizing military network resources and planning a core network with a mobile mechanism to enhance the military capability of mobile communication is an important issue. In this thesis, a NLMIP mobile network structure with Mobile IP function and the feature of local management is proposed. It is built upon a local network. By means of the mechanism of core network, it provides the capability of seamless mobile communication to the IP network users. The NLMIP can be used in a variety of applications such as VOIP, real time video, tele-monitoring, command transmission, GPS, etc. The NLMIP also provides a digital integrated platform for the military. It improves the problem of communication equipment shortage of the push-to-talk. The planning and operation mechanism of the NLMIP are discussed. The optimization and the application issues are also discussed to offer a reference of building a military mobile communication network.
