Problems solved by technology

[0005] The load of the target cell selected by the serving cell may also be relatively large. If the serving cell switches part of its own load to the target cell, it may cause the target cell to initiate a load switch, thus causing ping-pong switching.

Embodiment Construction

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0077] figure 1 It is the networking scenario applied in the embodiment of the present invention, see figure 1 , the networking scenario is a network scenario in which the macro base station and the micro base station are jointly networked. When the normalized load on the serving cell of the micro base station is relatively large, a load balancing method on the macro base station is obtained through the implementation of the present invention. The cell is the target cell, and part of the load on the serving cell is switched to the target cell, and the detailed process of the load balancing method provided by the embodiment of the present invention will be described in detail later.

[0078] see figure 2 , the embodiment of the prese...

Abstract

The invention provides a load balancing method and an apparatus, which relate to the communication field. The method comprises: obtaining an object zone, wherein the object zone is the different frequency neighborhood zone of a service zone, the normalized load difference between the service zone and the object zone proceeds a preset load threshold; and obtaining one or more user switching devices UE, wherein the sum of the normalized load is less than 1 / 2 of the normalized load difference between the service zone and the object zone, and the obtained switching device UE is switched from the service zone to the object zone. The apparatus comprises a first obtaining module, a second obtaining module and a switching module. According to the invention, 'ping pong' switching phenomenon is prevented.

Description

technical field [0001] The invention relates to the communication field, in particular to a load balancing method and equipment. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, macro base stations and micro base stations are used to jointly network to improve cell coverage in areas with high traffic volume. When the load of cells on micro base stations is large, micro base stations can use load balancing The method switches part of the load of the cell to the cell of the macro base station, so as to realize the load balance between the two cells. [0003] At present, the existing technology provides a method of load balancing, which can be specifically as follows: the serving cell on the micro base station detects its current load size, and if the current load size exceeds the preset threshold, the serving cell selects a macro base station. The cell is the target cell, and a part of the load is selected from its own current load, ...
