Load balancing method and equipment

Abstract

The embodiment of the invention discloses a load balancing method, which comprises the following steps of: acquiring load information of a plurality of neighbor cells and the load information of the neighbor cells of the plurality of neighbor cells; determining target cells of the mobility load balancing (MLB) according to the load information of the plurality of neighbor cells and the load information of the neighbor cells of the plurality of neighbor cells; and performing load balancing according to the target cells of the MLB. In the embodiment of the invention, when the load difference among the plurality of neighbor cells is not large, the method considers the load information of the neighbor cells of the plurality of neighbor cells and determines the target cells of the MLB according to the load information of the neighbor cells of the plurality of neighbor cells so as to more comprehensively select the target cells of the MLB, guarantee the stable operation of the system and be beneficial for achieving the load balancing effect of the whole network.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a load balancing method and equipment. Background technique [0002] In the existing MLB (Mobility Load Balancing, mobile load balancing) scenario, when the load of a cell is too heavy, the cell needs to negotiate with neighboring cells to do MLB. Neighboring cells, thereby reducing the load of the cell. Among them, the cell needs to exchange load information with neighboring cells, and by adjusting the handover parameters, the heavy-load cell can distribute the traffic to the light-load cell, so as to realize load balancing. [0003] Such as figure 1 A schematic diagram of MLB in a multi-cell scenario is shown. Cell D and cell A are adjacent cells to each other, cell A and cell B are adjacent cells to each other, and cell B and cell C are adjacent cells to each other. Assuming that the load of cell A is too heavy, cell A needs to negotiate MLB with neighbori...

AI Technical Summary

Problems solved by technology

If the traffic distribution of cell A is completed, cell C may not be able to distribute the load to cell B evenly, thus affecting the MLB effect of cell C, making the effect of MLB between cell A and cell B, cell C and cell B not good, which may cause It will lead to unstable operation of the system, and even the phenomenon of ping-pong MLB, which cannot achieve the effect of load balancing optimized by the entire network
