| 中文摘要 | 地面通信虽然很发达，但很难实现全球无盲区通信，如海洋、沙漠中存在许多通信盲区。而卫星通信能够实现全球全覆盖通信。卫星通信系统主要由卫星、地面站和用户终端组成。本文重点描述了卫星通信系统中，终端RRC子系统的设计、实现和测试。第二章详细描述了RRC子系统具有的功能及RRC的状态机。如RRC连接管理、RB连接管理、小区更新、安全模式等功能，其中重点突出了对小区更新，安全模式的论述。本章节详细描述了RRC的每一个功能，并且给出了MES同GERAN之间的信令交互图；详细描述了RRC的每一个状态，描述了RRC在各个状态下所具有的资源及功能，以及RRC如何在各个状态之间转换。第三章详细描述了RRC子系统的设计。描述了RRC子系统的架构设计、状态机设计、同上下层交互的队列设计以及RRC的功能设计。同时突出了本文的重点与创新点是状态机设计、小区更新和安全模式。本文分别描述了四种场景下的小区更新过程。第四章描述了RRC子系统的实现，提供了实现各个功能的流程图，还对一些核心的代码做了描述。本章节还描述了RRC子系统的测试过程，单元测试、集成测试和系统测试。提供了明确的测试目标、详细的测试案例及测试结果。本文详细描述了RRC子系统的设计、实现、测试的各个环节，通过本文，您可以看到一个完整的RRC子系统。 |
| 英文摘要 | Although terrestrial communication is significantly developed, it is still difficult to realize global communication with blind regions, such as in ocean and desert. However, the satellite communication has the ability to achieve the full coverage on global communication, which mainly consists of satellite, ground station and user terminal. In this paper, we focused on the design, realization and test of terminal RRC subsystem in the satellite communication system. The second chapter discusses the functions of RRC subsystem including RRC connection management, RB connection management, cell update, security mode, and other functions, in which cell update and security model were given prominence. The second chapter illustrates each function of RRC in detail, such as the signaling interaction diagram between MES and GERAN. Moreover, this chapter also demonstrates each RRC state in detail, including the resources and functions in each RRC state and RRC conversion between various RRC states. The third chapter discusses the design of RRC subsystem, involving architecture design, state machine design, queue design for communications between up and down layers and function design. Besides, the third chapter highlights the focus and innovation of this paper, that is, state machine design, cell update and security model. Furthermore, this paper explores the cell update process under four different settings. The fourth chapter discusses the realization of RRC subsystem via providing flowcharts to realize each function and some core codes. Besides, the fourth chapter describes the testing process of RRC subsystem, including unit test, integration test and system test, which provides clear test objectives, detailed test cases and test results. This paper discusses the design, realization and test of RRC subsystem, which provides a full picture of a complete RRC subsystem. |
