碩士 === 國立臺灣科技大學 === 資訊工程系 === 106 === Radio access network virtualization, its main concept is to abstract and share infrastructure the radio resources. To implement the software radio technology, the base station is splitted into a hardware remote radio frequency RRH and a software base frequency component BBU, which can significantly reduce the cost of deployment and operation, save energy and improve resource efficiency. Therefore, it is a key technology to achieve the strict requirements of 5G mobile communication network with high efficiency and low latency. And in the 5G new radio, 3GPP further splits the eNB into two parts: CU (Centralized Unit) and DU (Distributed Unit), which hope to increase network traffic processing speed, network bandwidth and reduce network latency. Our paper addresses the virtualization of centralized radio access networks, use USRP hardware and combined with OpenAirInterface, which is the open source software, and use Docker, which is open source container technology, we also use Kubernetes for management, implement a portable, low-cost and energy-efficient 5G radio access network virtualization experiment platform, which is completely includes components such as the BBU resource pool and the core network. In our experiment platform, we manage lightweight Docker through Kubernetes, and dynamically switch containers to efficiently configure BBUs to RRHs, which will reduce deployment costs and increase efficiency. The overall plan will not only explore the key features needed to meet 5G mobile communication technologies, also experiment various possible solutions and feasibility on our experiment platform.
