Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] Such as figure 1 As shown, it is a flow chart of the steps of the load balancing method in the embodiment of the present invention.

[0024] Specifically, the load balancing method can be applied to devices provided at the X2 interface between base stations, so as to be able to receive cell information in real time through the X2 link.

Abstract

The embodiment of the invention provides a load balancing method and device. The method comprises the following steps: obtaining a candidate neighbor cell list of a serving cell when the reporting information, reported by a source base station, that a terminal serving cell meets a load balancing starting condition is received, and obtaining the state parameter of each candidate neighbor cell in the candidate neighbor cell list; selecting a target cell for cell switching from the candidate neighbor cell list according to the state parameter of each candidate neighbor cell; and sending switchinginformation carrying the cell identifier of the target cell to the source base station, so that the source base station sends a serving cell switching request to the target base station to which thetarget cell belongs according to the switching information, thereby switching the terminal from the serving cell to the target cell. According to the embodiment of the invention, the consumed time ofthe whole load balancing process is reduced, and the time delay is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a load balancing method and device. Background technique [0002] With the promotion of speed increase and fee reduction by operators, traffic charges continue to drop, which leads to explosive growth of indoor LTE traffic. With the increase of indoor LTE business volume, that is, the increase of user load, the indoor distribution system must carry out multi-frequency expansion again and again on the original basis, and in order to ensure that the huge user load can be evenly shared in each cell, it is necessary to Perform load balancing. [0003] At present, when performing room division and same coverage load balancing of terminals, the base station first needs to select the target cell for load balancing. At this time, the base station first screens candidate target cells from the configured inter-frequency adjacent cells, and then the ba...
