【摘要】：在实现下一道移动通信网络(5G)的愿景过程中,华为公司提出了面向SDN技术的SONAC和MyNet,根据不同网络部署和业务需求的需要,利用软件定义无线网络控制和数据分离的特点,构建与之相匹配的定制化网络服务切片,为用户提供按需的网络服务。在基于网络切片的无线定制网络中,为了实现网络服务切片的灵活配置和管理以及定制化的数据传输,我们可以采用软件定义协议栈(SDP)的方式,将传统移动通信网络中的网络功能和数据传输协议栈,看作多个独立的逻辑功能单元组成。因此,基于SDN技术的网络切片实现将是值得研究的一个方向。本文首先分析了华为公司提出的MyNet网络以及SONAC技术,重点分析了SDP平台在MyNet网络架构中的功能。为实现SDP服务定制化的功能,本文提出将LTE协议中数据链路层进行解耦,使其模块化成为单独的功能模块。其次,重点分析研究了数据链路层中MAC、RLC和PDCP三个子层的协议、功能等,为后续解耦操作做好技术基础。最后并从代码层次分析,分别重构每个子层的功能设计,包括输入输出的重设计。通过设计测试方案分析,本论文提出的解耦方案能够达到预期目标。
[Abstract]:In the process of realizing the vision of the next mobile communication network, Huawei puts forward SONAC and MyNet, which are oriented to SDN technology. According to the needs of different network deployment and business requirements, Huawei uses software to define the characteristics of wireless network control and data separation. In order to realize the flexible configuration and management of the network service slice and the customized data transmission in the wireless customized network based on the network slice, a customized network service slice is constructed to provide the users with on-demand network service slice. We can use the software definition protocol stack (SDP) to regard the network function and data transfer protocol stack in the traditional mobile communication network as several independent logical function units. The realization of network slicing based on SDN technology will be a research direction. Firstly, this paper analyzes the MyNet network and SONAC technology proposed by Huawei. The function of SDP platform in MyNet network architecture is analyzed emphatically. In order to realize the function of SDP service customization, this paper proposes to decouple the data link layer in LTE protocol and make it modularized into a separate functional module. The protocol and function of MAC RLC and PDCP in the data link layer are analyzed and studied in order to lay a good technical foundation for the subsequent decoupling operation. Finally, the function design of each sub-layer is reconstructed from the code level analysis. Through the analysis of the design and test scheme, the decoupling scheme proposed in this paper can achieve the expected goal.
