Inter-cell load balancing method and device

Abstract

The embodiment of the invention discloses an inter-cell load balancing method and device. The inter-cell load balancing method comprises the following steps that a first base station receives a first resource state request message which comprises a cell identifier of a cell to be measured; judging whether the cell to be measured is in an abnormal state, if so, the resource state of the cell in the abnormal state is set according to the type of the abnormal state of the cell in the abnormal state; if not, the cell in the non-abnormal state is measured to obtain the resource state of the cell in the non-abnormal state; the first base station sends a resource-state updating message to the second base station. The inter-cell load balancing method and device disclosed by the embodiment of the invention have the advantages that the setting of the resource state of the cell in the abnormal state according to the type of the abnormal state of the cell in the abnormal state and the returning of the resource state to the second base station are realized, so that the adjustment of load balance can be carried out by the second base station according to the returned resource state of the cell, and the effectiveness of the load-balance adjustment is provided.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for balancing loads between cells. Background technique [0002] Mobility Load Balancing (MLB) in LTE SON (Self-Organized Network, self-organizing network) means that the wireless cellular system can detect overloaded cells without manual intervention, and automatically execute the load balancing algorithm to reduce the overloaded cells A part of the business is transferred to the adjacent cell with relatively light load. The load transfer is mainly realized through the specific means of switching. In actual engineering, the A3 event is generally used to trigger the measurement report of LTE co-frequency handover, and the coverage of the cell is indirectly changed by adaptively modifying the relative offset of the cell (Cell Individual Offset, CIO) and hysteresis parameters, so that the channel condition at the edge of the hot spot cell Poor...

Problems solved by technology

[0004] The embodiment of the present invention provides a method and device for inter-cell load balancing, which is used to solve the resource status returned by the management base station of the adjacent cell of the overloaded cell when an abnormal cause occurs in the adjacent cell of the overloaded cell during the inter-cell load balancing process The update message failed to accurately reflect the load situation of the adjacent cells of the overloaded cell, and caused the management base station of the overloaded cell to fail to switch the edge UE of the overloaded cell to a suitable adjacent cell, thereby reducing the effectiveness of load balancing adjustment.
