Intelligent controller and distributed indoor distribution 5G system multi-cell load balancing method

Abstract

The invention discloses an intelligent controller and a distributed indoor distribution 5G system multi-cell load balancing method. The intelligent controller comprises a decision-making module, and aservice monitoring module, a cell spectrum utilization rate monitoring module and a cell configuration module which are in communication connection with the decision-making module. The method comprises the following steps: 1, uniformly configuring remote units for cells according to initial conditions; 2, monitoring and determining the traffic load condition of each remote unit; 3, monitoring anddetermining the spectrum utilization rates of all cells; 4, determining whether the cells need to be reconfigured or not to obtain reconfiguration information; and 5, adjusting the membership relationship between the current remote unit and the cells, and reconfiguring the cells. According to the method, the problem of non-uniform load of multiple cells is solved, and the frequency spectrum of the system and the utilization rate of the processing capability are greatly improved.

Description

technical field [0001] The invention belongs to the field of 5G communication, and specifically refers to an intelligent controller and a method for multi-cell load balancing of a distributed indoor 5G system. Background technique [0002] Distributed small base stations are the main form of equipment for indoor coverage in the 5G era. Due to the high frequency and high penetration loss of 5G, it is difficult to cover indoors through outdoor macro base stations. Only indoor small base stations can provide excellent indoor coverage and throughput. 5G distributed small base stations have become the mainstream indoor coverage solution due to their low cost, good coverage, and strong scalability. Such as figure 1 As shown, a distributed small base station system is composed of the following units, the central unit (Central Unit), the extended unit (Extended Unit) and the remote unit (Remote Unit), wherein the central unit is responsible for the centralized processing of data, ...
