【摘要】：如今新一代卫星移动通信系统大多数都支持GMR-1 3G(GMR,Geostationary earth orbit Mobile Radio interface)标准,该标准是由欧洲电信标准化研究所ETSI(European Telecommunications Standards Institute)发布的地球同步轨道卫星移动通信空中接口技术规范,从基于GSM(Global System for Mobile communication)标准的通信系统GMR-1演化而来。GMR-13G通信系统为地面提供基于同步卫星的3G移动通信业务,而如何保证对通信过程中控制信令的有效处理并进行可靠传输是整个系统研究实现中需要解决的重要问题。与GMR-1先前发布的版本相比,空中接口协议部分的第三层即RRC(Radio Resource Control)层的功能发生了较大的改变,控制管理功能主要集中在了RRC层中,状态控制及协议中规定的连接状态也发生了相应的变动。本文关于GMR通信系统无线资源控制层协议软件的设计与实现就是以解决上述问题为基础,依附于整个GMR-1 3G协议栈系统软件,最终完成了RRC无线资源控制层的主体功能,即对通话过程和入网过程中控制信令进行有效的处理。本文是以GMR-1 3G标准的基站侧空中接口协议为基础,在对协议总体有所了解之后,对RRC层协议进行了详细的分析和研究,然后设计并编码实现了协议中对RRC层关于控制消息的处理功能。在RRC系统设计过程中,将其划分为模块设计和过程设计。在实现过程中,是基于Vx Works实时操作系统的Workbench集成开发环境和C语言来实现代码的编写和编译,并使用基于Vx Works实时操作系统的AM4140板卡来完成对RRC系统的功能和协议的一致性验证。本文所设计的RRC层系统架构和基于Vx Works操作系统的C语言实现,很好的完成了RRC层对来自各层的控制消息、请求及其它事件的处理,实现了RRC过程在一次资源分配下的流程控制。通过和终端、核心网的联合测试,RRC层能完成终端入网和通话过程中协议规定的所有功能。
[Abstract]:Today, most of the new generation of satellite mobile communication systems support GMR-1 3G (GMR,Geostationary earth orbit Mobile Radio interface) standard). The standard is a technical specification for the air interface of geosynchronous orbiting satellite mobile communications issued by the European Institute for Telecommunications Standardization (ETSI (European Telecommunications Standards Institute). Evolved from GMR-1, a communication system based on GSM (Global System for Mobile communication) standard. GMR-13G communication system provides 3G mobile communication services based on synchronous satellites for the ground. How to ensure the effective processing and reliable transmission of control signaling in the communication process is an important problem to be solved in the research and implementation of the whole system. Compared with the previous version of GMR-1, the function of the third layer of the air interface protocol, that is, the RRC (Radio Resource Control) layer, has been greatly changed, and the control and management functions are mainly concentrated in the RRC layer. The state control and the connection state specified in the protocol have also changed accordingly. In this paper, the design and implementation of wireless resource control layer protocol software for GMR communication system is based on solving the above problems, attached to the whole GMR-1 3G protocol stack system software, and finally completed the main function of RRC wireless resource control layer. That is to say, the control signaling in the process of calling and entering the network is processed effectively. This paper is based on the base station air interface protocol of GMR-1 3G standard. After understanding the protocol as a whole, the RRC layer protocol is analyzed and studied in detail. Then the processing function of control message in RRC layer is designed and encoded. In the process of RRC system design, it is divided into module design and process design. In the process of implementation, the Workbench integrated development environment and C language based on Vx Works real-time operating system are used to write and compile the code. The AM4140 board based on Vx Works real-time operating system is used to verify the function and protocol of RRC system. The RRC layer system architecture and the C language implementation based on Vx Works operating system are designed in this paper, and the RRC layer processes the control messages, requests and other events from each layer very well. The process control of RRC process under the primary resource allocation is realized. Through the joint test with the terminal and the core network, the RRC layer can complete all the functions specified in the protocol during the terminal access to the network and the call process.
