Abstract

The embodiment of the invention discloses an inter-cell mobility load balance method and the embodiment of the invention also discloses a mobility load balance device. The method includes the following steps: a service base station measuring a user number occupation ratio and a resource occupation ratio of a service cell and when the user number occupation ratio b1 of the service cell exceeds a corresponding threshold t1 or the resource occupation ratio b2 exceeds a corresponding threshold t2, obtaining user number occupation ratios and resource occupation ratios of all adjacent cells of the service cell; and according to user number occupation ratio difference values and resource occupation ratio difference values of the service cell and the adjacent cells of the service cell, selecting a first adjacent cell from all the adjacent cells to carry out load balance processing with the service cell, wherein the load balance processing includes at least one of user number balancing and resource load balancing. Compared with the prior balance methods, the inter-cell mobility load balance method is lower in complexity and capable of better maintaining system balance and stability and ensuring service quality to all users and providing a flexible load balance processing method to operators.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a mobile load balancing device for inter-cell mobile load balancing. Background technique [0002] Self-Organization Network (SON) mainly includes three parts, self-configuration, self-optimization and self-healing. The relevant protocols and white papers in the self-optimization part mainly include Mobility Robust Optimization (MRO) and Mobility Load Balance (MLB). MRO realizes the optimization of handover threshold parameters, reducing premature, too late, and ping-pong handovers; MLB also adjusts user-level handover parameters to allow specific users to handover to target cells based on load reasons, achieving network load balance, stabilizing network services, and improving The user's overall perception of purpose. [0003] The existing MLB only considers resource occupancy, including physical resource block (Physical Resource Block, PRB) occupancy, hard...
