摘　　要：模块化设计思想是支持超级基站协议软件多制式共平台的核心,而PDCP作为协议软件不可或缺的一层,也应当能支持多制式协议流程。现有的PDCP层实现方式,未能充分考虑超级基站协议栈多制式共平台的特点,支持协议流程切换灵活度低。针对该问题,PDCP层设计提出组件化的设计方法,定义了组件间通信方式,采用动态库的形式,通过相应功能库的添加、删除和扩展,能自组织、自生成相应的协议流程。仿真结果表明,通过读取配置文件,进行相应功能库的替换,提出的组件式设计方案能在满足功能和性能的基础上,灵活替换功能库,自生成相应协议流程,符合超级基站协议软件的特点。本研究能够为自定义网络和协议栈其余各层的实现提供参考。The modular design idea is the core of the multi-system common platform supporting the super base station protocol software. As an integral part of protocol software, PDCP should also be able to support multi-standard protocol processes. The existing implementation of the PDCP layer hardly switches the protocol process flexibly, thus fails to support the characteristics of the multi-standard common platform of the super base station protocol stack. In order to solve this problem, a componentized design method is proposed in the PDCP layer design. Firstly, the way of communication between components is defined. Then, in the form of a dynamic library, through the addition, deletion and expansion of the corresponding function library, the corresponding protocol flow can be self-organized and self-generated. The simulation results show that by reading the configuration file and replacing the corresponding function library, the proposed component design solution can flexibly replace the function library on the basis of satisfying the function and performance, and generate the corresponding protocol flow, which meets the features of the super base station protocol software. This study can provide a reference for the implementation of the custom network and the rest of the protocol stack.
