【摘要】：在實現(xiàn)下一道移動通信網(wǎng)絡(5G)的愿景過程中,華為公司提出了面向SDN技術的SONAC和MyNet,根據(jù)不同網(wǎng)絡部署和業(yè)務需求的需要,利用軟件定義無線網(wǎng)絡控制和數(shù)據(jù)分離的特點,構建與之相匹配的定制化網(wǎng)絡服務切片,為用戶提供按需的網(wǎng)絡服務。在基于網(wǎng)絡切片的無線定制網(wǎng)絡中,為了實現(xiàn)網(wǎng)絡服務切片的靈活配置和管理以及定制化的數(shù)據(jù)傳輸,我們可以采用軟件定義協(xié)議棧(SDP)的方式,將傳統(tǒng)移動通信網(wǎng)絡中的網(wǎng)絡功能和數(shù)據(jù)傳輸協(xié)議棧,看作多個獨立的邏輯功能單元組成。因此,基于SDN技術的網(wǎng)絡切片實現(xiàn)將是值得研究的一個方向。本文首先分析了華為公司提出的MyNet網(wǎng)絡以及SONAC技術,重點分析了SDP平臺在MyNet網(wǎng)絡架構中的功能。為實現(xiàn)SDP服務定制化的功能,本文提出將LTE協(xié)議中數(shù)據(jù)鏈路層進行解耦,使其模塊化成為單獨的功能模塊。其次,重點分析研究了數(shù)據(jù)鏈路層中MAC、RLC和PDCP三個子層的協(xié)議、功能等,為后續(xù)解耦操作做好技術基礎。最后并從代碼層次分析,分別重構每個子層的功能設計,包括輸入輸出的重設計。通過設計測試方案分析,本論文提出的解耦方案能夠達到預期目標。
[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.
