Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] Such as figure 1 As shown, the load balancing method based on business prediction in this embodiment includes:

[0035] In step S101 , using a preset time period as a unit, different business forecasting models are used to predict the traffic volume in different time periods. In this embodiment, the horizontal division of 24 hours a day is divided into 24 time periods. Each time period adopts different business forecasting models to predict the business volume in the time period, that is, there are 24 business forecasting models. Before prediction, collect the data reported by all base stations in a cell, and extract the traffic volume of voice and data correspon...

Abstract

The invention discloses a service prediction based load balancing method which relates to the technical field of wireless communication. The service prediction based load balancing method includes the following steps of firstly, presetting a time range as a unit, predicting service quantity in different time ranges by different service prediction models; secondly, predicting service quantity of the next load balancing processing period according to the different service prediction models, configuring service request dispatch results in advance so as to balance load. In the service prediction based load balancing method, service prediction models are built in each time range, the advantages of building models for service quantity in different time ranges include that a great quantity of iterative computations is reduced due to the fact that varying trends of the time ranges are basically same, design complexity is reduced, and convergence speed of the prediction models is increased. Besides, the service prediction based load balancing method is easy to realize.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a load balancing method based on service prediction. Background technique [0002] The purpose of the load balancing algorithm is to realize the uniform distribution of business in the system, reduce the congestion caused by excessive local load, and improve the system capacity. However, most of the current load balancing algorithms are based on the current load situation of the network, that is, they operate after knowing that the network load is congested. This situation is called the hysteresis effect. The hysteresis effect of load balancing will reduce the efficiency of the load balancing algorithm and cause localized congestion for a certain period of time. Therefore, a load balancing algorithm based on business forecasting emerges as the times require. Its core idea is to know the business volume of the system at the next moment in advance through business ...
