摘要
为了实现LTE系统中RRC连接建立的需求,提出了一种对RRC层连接过程进行设计的方案,并完成系统的软件设计。该系统将RRC层的空闲状态和连接状态均细分为两个子状态,有效降低了系统设计的复杂度。软件采用Xilinx SDK工具集进行开发,通过在PC上分别模拟终端和基站进行测试,终端和基站能够成功接收到正确的RRC消息。实验结果表明,该系统能够成功的建立RRC连接,达到了设计的要求。
Oriented at the RRC connection establishment in LTE system, one scheme has been proposed by this paper. Both idle state and connection state in RRC layer are divided into two sub-states. In this way, the complexity of the system design has been reduced considerably. The simulation software is developed with the Xilinx SDK suits. Both UE and eNodeB can successfully receive the correct RRC messages in the simulation environment running in the PC. Experimental results show that the system is able to establish the RRC connection successfully, which achieve the design requirements.
