一种卫星移动通信终端协议栈NAS层模块设计

Design of a NAS layer of terminal protocol stack of satellite mobile communication

针对我国对卫星移动通信系统的需要,文章介绍了一种卫星移动通信终端协议栈NAS层模块的设计。文章首先介绍了卫星移动通信系统空中接口协议的层次结构,然后通过介绍卫星移动通信终端软件架构来引出协议栈NAS层模块在整个协议栈中的位置和角色,最后对NAS层模块的设计原理和原则进行阐述。本设计适应我国当前卫星移动通信系统的需要,对后续我国自主研发卫星移动通信系统的终端协议栈具有一定的借鉴意义。

According to the needs of our satellite mobile communication system, the design of NAS layer module of satellite mobile communication terminal protocol stack is introduced in this paper. Firstly, this paper introduces hierarchy of air interface protocol in satellite mobile communication system. Then, the mobile satellite communication terminal software architecture is expounded to introduce the position and role of NAS protocol stack module in the protocol stack. Finally, the design principles of NAS layer module are expounded. The design meets the needs of the current satellite mobile communication system in China, it has certain reference significance for the independent research and development of terminal protocol stack of our country＇s satellite mobile communication system.
