Embodiment Construction

[0016] The embodiment of the present invention realizes setting the resource state of the abnormal state cell according to the abnormal state type of the abnormal state cell, and returning it to the second base station, so that the second base station can adjust the load balance according to the returned resource state of the cell , improving the effectiveness of load balancing adjustments.

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

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...
