Network slice resource arrangement and mapping method based on 5G

Abstract

The invention discloses a 5G-based network slice resource arrangement and mapping method, and aims to solve the problem that in a smart power grid scene, 5G network slice resource arrangement cannot give consideration to QoS requirements of a power terminal on time delay, rate, reliability and the like. According to the method, an end-to-end network slice arrangement and mapping model oriented to power business is divided into a bottom physical infrastructure layer, a slice instance layer and an application service layer, and then an end-to-end global time delay minimization function is provided on the premise of ensuring the minimum transmission rate and reliability of the slice; and finally, dividing priorities according to three aspects of a power slice service function chain, a virtual network function unit and physical node resources, screening and pruning each candidate node matching pair, and iteratively solving to ensure the time delay, rate and reliability requirements of the power business, thereby greatly reducing the end-to-end global time delay, and improving the reliability of the power business. And the satisfaction degree of users of the bottom physical infrastructure layer is improved.

Description

technical field [0001] The present invention relates to the field of electric power wireless communication, in particular to a 5G-based network slicing resource arrangement and mapping method. Background technique [0002] In recent years, with the continuous development of the smart grid, the demand for power terminals in the smart grid has exploded, and the control business has put forward higher requirements for delay and reliability. 5G network slicing based on virtualization is considered to be a promising and future technology. It realizes the abstraction of underlying physical resources and the virtualization of upper-layer functions, which can achieve the purpose of future network programmability and resource sharing, so as to more flexibly meet Fragmented, customized, and differentiated vertical industry needs. At present, most domestic and foreign research on network slice resource orchestration only considers the core network side or the access network side, and ...
