摘要
从3GPP协议出发,分析了近年来LTE系统中提出的无线资源控制(RRC)连接建立消息传输过程中消息数据及控制信息的交互,设计定义层间接口原语及参数描述,提出一种在层间进行通信的优化方案,简化了当前系统设计中的接口原语量,并给出了相应设计的消息序列图。采用该方案能有效简化系统实现复杂度和提高资源利用率。
According to the 3GPP protocol, this paper analyses the message data and control information in the interaction of the RRC (Radio Resource Control) connection setup message transmission process, which is proposed by LTE system in recent years. The interfaces primitives between layers and parameters description are defined, and a communication optimization scheme between the layers is proposed in order to simplify the amount of interfaces primitives in the current system design and the corresponding design of message sequence chart. The scheme can effectively simplify the system implementation complexity and improve resource utilization.
