Method for load balancing between base stations and base station

Abstract

The invention discloses a method for load balancing between base stations and the base station. The method comprises the following steps that a first cell determines whether to carry out load balancing between the base stations at every first preset time based on an RRC connection user number of the cell; after the first cell determines to carry out load balancing between the base stations, the first cell determines whether a request message of the RRC connection user number is sent to each second cell, wherein the second cell is an adjacent cell which is in the same coverage as the first cellbetween the base stations; the first cell determines a target cell with the balanced load between the base stations based on the RRC connection user number fed back by each second cell at every second preset time; and the first cell determines target users which are balanced in the cell and triggers the target users to switch to the target cell, so that the load balancing between the base stations is achieved According to the method and the base station, the interaction of the RRC connection user number between the base stations is carried out through a private interface message, and a problem that the load balancing between the base stations cannot be realized due to the fact that the RRC connection user number of the adjacent cell between the base stations cannot be acquired in the prior art is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for load balancing between base stations and a base station. Background technique [0002] In hotspot areas where the number of users is concentrated, in order to solve the problem of Radio Resource Control (RRC) connection capacity, multi-layer networking is usually used to share the pressure, including multi-layer networking within the base station and co-coverage networking between base stations . How to make users evenly distributed in each co-coverage cell has become an important issue. For co-coverage cells in the base station, the number of users of each other can be known between the cells, and load balancing based on the number of RRC connected users can be used. However, for co-coverage cells between base stations, since each other does not know the number of users of the other party, the existing communication protocol does not specify how to obtain t...

Problems solved by technology

[0012] 31. Filter out users who do not support the frequency band of the target cell

[0019] It can be seen that the existing technology only considers the user balance between adjacent cells in the base station, and cannot solve the problem that the number of users in the adjacent cells with the same coverage varies greatly between base stations, which will cause some base stations to be crowded and other base stations with the same coverage to be idle
