5g network slicing method for smart power grid

Abstract

The invention discloses a 5g network slicing method for a smart power grid. The method comprises the following steps: S1, firstly accessing and transmitting, and performing network slicing on a network of an external terminal by a core network domain slicing enabling system; S2, mapping a network slice instance and a terminal service type by a network slice identifier and an access system, and registering a terminal to a correct network slice instance. The method has the beneficial effects that the network slice instance of the access, transmission and core network is realized by taking an access, transmission and core network domain slice enabling system as a basic support technology; mapping between the network slice instance and the terminal service type is realized through the network slice identifier and the access system, and the terminal is registered to the correct network slice instance; arrangement and management of end-to-end network slices are realized through a network slice end-to-end management system; through the network slice end-to-end SLA guarantee system, acquisition analysis and quasi-real-time processing can be carried out on network performance indexes of each domain, and it is guaranteed that the performance of the system meets the SLA requirement of a user.

Description

technical field [0001] The invention relates to the technical field of network slicing, in particular to a 5G network slicing method of a smart grid. Background technique [0002] Network slicing is an on-demand networking method that allows operators to separate multiple virtual end-to-end networks on a unified infrastructure. Each network slice performs logic from the radio access network bearer network to the core network. isolation to suit a wide variety of applications. A network slice can be divided into at least three parts: wireless network sub-slice, bearer network sub-slice and core network sub-slice. With the development of 5G network, the existing network slicing method is not particularly mature for 5G network, the supporting technical conditions are insufficient, the network is difficult to access, and the terminal is difficult to connect with the network slicing system, and the end-to-end network slicing Arrangement and management are cluttered and difficult...
