Zhou Tong, Tiankui Zhang, Yutao Zhu, Rong Huang · 2020
In the mobile network, to better meet various vertical industries applications, network slicing is required in both the mobile core network and the access network to achieve end-to-end network slicing. This paper proposes a framework of end-to-end mobile network slicing. We model an end-to-end delay minimization problem based on the proposed framework. Then we propose a communication and computation resource joint allocation algorithm in end-to-end network slicing for ultra-reliable low-latency communication (URLLC). In the process of network slice orchestration and deployment, the virtual network function (VNF) mapping in the core network and the wireless resource allocation in the access network are jointly considered to minimize the end-to-end delay that ensures the reliability of the network slice. The simulation results show that the proposed algorithm can effectively reduce the end-to-end latency of network slicing, and guarantee the reliability requirements of network slicing as well.
