Centralized unit and distributed unit fusion deployment system, related method and equipment

Abstract

The invention belongs to the technical field of 5G network security, and discloses a centralized unit and distributed unit fusion deployment system, a related method and equipment. The method comprises the following steps: deploying CU-DU server equipment and external CU server equipment in a network where core network equipment is located; when the resource utilization detection parameter detected in real time exceeds a preset upper limit threshold value, judging whether resource elegant switching needs to be carried out at present or not; if the CU-DU needs to be switched, switching the CU-DU from centralized deployment to distributed deployment; when the resource utilization detection parameter is lower than a preset lower limit threshold value, whether resource elegant switching needs to be carried out or not is judged; if the CU-DU needs to be switched, switching the CU-DU from distributed deployment to centralized deployment; otherwise, switching is not carried out. When the 5G resource utilization rate changes, elegant switching is carried out in real time according to the resource consumption condition, the performance bottleneck of the 5G base station with CU-DU centralized deployment is solved, and the resource expandability and the system reliability of the 5G base station are improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a centralized unit and distributed unit fusion deployment system, related methods and equipment. Background technique [0002] The BBU software of the 5G access network system is divided into two logical nodes: CU (Central Unit, centralized unit) and DU (Distributed Unit, distributed unit). The advantage of using the CU-DU architecture for the BBU software of the 5G access network system is that it can obtain inter-cell cooperation gains and realize centralized load management; efficiently realize centralized control under dense networking, such as multi-connection and intensive switching; obtain pooling gains , enabling NFV / SDN to meet the deployment requirements of operators in certain 5G scenarios. Among them, CU is a centralized node, including sublayer functions of the protocol stack RRC (air interface resource control), SDAP (service data application unit...

AI Technical Summary

Problems solved by technology

In this deployment mode, the hardware cost is saved, but the user access volume or user business volume may exceed the processing capacity of the hardware server, resulting in performance bottlenecks in the base stations deployed by CU-DU, thereby affecting user access or business to experience

[0006] Therefore, there are certain problems or limitations in the deployment of 5G base stations in places where the number of users and business volume are uncertain, and whether to choose centralized deployment or distributed deployment
