A load balancing adjustment method and device for a serving cell

Abstract

The embodiment of the invention discloses a method and a device for adjusting load balance of a serving cell. The method comprises the following steps: obtaining resource block demands of a single user terminal in a preset time period according to XDR data of a service cell within a historical preset number of days, and determining the number of stable user terminals, occurrence probability of thestable user terminals, the number of unstable user terminals and the occurrence probability of the unstable user terminals; according to the resource block demand quantity, the stable user terminal quantity, the stable user terminal occurrence probability, the unstable user terminal quantity and the unstable user terminal occurrence probability of a single user terminal, predicting the maximum resource block demand quantity within a preset time period; and if it is judged that the maximum demand of the resource block is greater than a threshold value, adjusting the load balancing parameter ina preset time period. The device is used for executing the method. According to the load balancing adjustment method and device for the serving cell provided by the embodiment of the invention, the stability of the wireless service provided by the serving cell is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular to a method and device for adjusting load balance of a serving cell. Background technique [0002] In order to provide corresponding wireless resources for various services of mobile communication users, the Long Term Evolution (LTE) network realizes seamless network coverage in the form of serving cells through outdoor base stations and indoor micro cells. During the user's movement, the user terminal selects a serving cell according to the level of the primary serving cell occupied by the user and the level of adjacent serving cells. In the same serving cell, if there are a large number of users and the user services are focused on high-speed services, there will be a problem that the wireless resources of the serving cell cannot meet the user access requirements, that is, user access congestion will occur. [0003] In view of the proble...

AI Technical Summary

Problems solved by technology

This equalization method determines the configuration of parameters in the future period from the perspective of the historical data of the serving cell, and cannot fine-tune the serving cell, and fails to effectively solve the problem of high load in the serving cell

This method also has the problem that the load balancing of global resources cannot be achieved after adjustment
