5G distributed and centralized hybrid networking method and 5G network system

Abstract

The invention provides a 5G distributed and centralized hybrid networking method and a 5G network system, and relates to the technical field of mobile communication and wireless broadband access, the method comprises the following steps: fusing a first target network function NF of a 5G core network with a base station function software code to obtain a fused distributed system; deploying the fusion distributed system on a base station side; deploying the second target NF of the 5G core network to the center in a centralized manner; the second target NF comprises a basic NF, and the basic NF comprises an element management system EMS, a unified data management UDM, an authentication service function AUSF, a policy control function PCF, a network storage function NRF and a network slice selection function NSSF; and setting an EMS (Energy Management System) to uniformly manage and fuse a distributed system and centrally deploy network elements. According to the invention, some NFs of the 5G core network can be deployed at the base station side according to actual demands, and the NFs can be arranged as required, so that the method can be applied to various mobility application scenarios such as a high mobile communication scenario, a low mobility scenario and a fixed wireless broadband access scenario, and the application scenarios are wide.
