Method and device for load balancing based on RRC connection

Abstract

The invention discloses a method and device for load balancing based on an RRC connection, used for realizing the load balancing timely in a multi-layer network. The method for load balancing based on the RRC connection comprises the following steps: when a preset balancing period is reached, determining whether the states of all terminals in a first cell that successfully establish the RRC connection satisfy the predetermined balancing condition or not; if the predetermined balancing condition is satisfied, screening out the terminals to be balanced according to the preset filter conditions; and cutting into the balancing target cell successively according to the preset priority order. According to the invention, the balancing process is performed periodically according to the preset balancing period, therefore, the timeliness of the load balancing is ensured; whether the cell needs load balancing or not is determined based on the number of the terminals that successfully establish the RRC connection, therefore, the high load cell can be found and handled timely; the terminal to be balanced is selected specially by means of the filter conditions, and the balancing is performed successively according to the preset priority order, therefore, the business experience of the balanced terminal is guaranteed, and the impact on non-balanced terminals is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for load balancing based on RRC connections. Background technique [0002] The Long Term Evolution (LTE) system of the fourth-generation communication technology has become a research hotspot in the field of mobile communication due to its advantages of small network delay, high data rate and low operating cost. The LTE system adopts multi-layer networking technology for network construction. In the actual networking process, the number of Radio Resource Control (RRC) connection terminals often occurs unevenly among multi-layer networks. This is not only in To a certain extent, it will cause waste of multi-layer network resources, and it will also lead to increased network delay, lower main performance indicators, and even lead to failure of RRC establishment and system downtime. Therefore, the problem of uneven distribution of the number of RRC connection t...

Problems solved by technology

[0039] For the above load balancing solution, when calculating the PRB utilization rate of a cell, it is necessary to calculate the accurate PRB utilization rate after the UE accesses the LTE system and processes services for a period of time, that is, the PRB utilization rate can only be calculated when the cell is in a high load state. The number of terminals in the cell is balanced, so the number of terminals in the high-loaded cell cannot be balanced in time, and the above-mentioned equalization scheme does not solve the problem of large differences between terminals in different layers of the multi-layer network

[0040] Based on the above analysis, the load balancing method in the prior art still has the problem that the number of terminals in different layers of the multi-layer network differs greatly, and the load cannot be balanced in time
