Embodiment Construction

[0021] As mentioned in the background, the current load balancing technology only considers the load conditions of the local cell and neighboring cells, but does not take into account the channel conditions of users who are forced to switch due to load balancing. After these users are forcibly handed over from the serving cell to the target cell, the wireless signal is bound to drop, which in turn leads to a drop in user service perception. If the power of the two cells is adjusted by the base station so that the coverage range changes with the change of the serving cell where the edge user is located, the wireless channel environment of the edge user will be further improved without changing the load condition.

[0022] In order to overcome such defects, the embodiment of the present invention proposes a load balancing method based on automatic adjustment of cell coverage. In the existing load balancing technology, the function of automatic adjustment of cell power is added to...

Abstract

An embodiment of the invention discloses a load balancing method and equipment based on automatic cell coverage adjustment. By application of the technical scheme, the cell reference signal power of an origin cell is decreased after edge users are switched out, and the cell reference signal power of a target cell is increased, so that signals of the origin cell can be weakened with switching out of the edge users, signals of the target cell can be strengthened with switching in of new edge users, and further respective coverage areas of the two cells are adjusted automatically with load of the two cells unchanged. Therefore, the edge users switching from the origin cell to the target cell due to load balancing requirement can receive stronger signals of the target cell under the circumstance of position invariance, undesired signal strength of the origin signal is reduced, wireless channel environment of the users switched out is optimized, and user service awareness is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a load balancing method and equipment for automatically adjusting coverage based on cells. Background technique [0002] The current load balancing technology mainly uses measures such as handover, modification of cell selection reselection parameters, or redirection when the base station determines that a cell has a high load, so that some users leave the cell and transfer to neighboring cells with lighter loads. In this way, the load can be redistributed from high cells to low cells. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The current load balancing technology only considers the load conditions of the local cell and neighboring cells, but does not take into account the channel conditions of users who are forced to switch due to load balancing. After these us...
