Load balancing method between base stations in heterogeneous network, and load balancing device between base stations in heterogeneous network

Abstract

Embodiments of the present invention provide a load balancing method, a device and a computer storage medium among base stations in a heterogeneous network. The load balancing method can be applied to a target base station in a first type of base stations and a second type of base stations in the heterogeneous network. The transmission power of the first type of base stations is larger than that of the second type of base stations, and at least one second-type base station is located in the coverage range of the first-type base station. The method comprises: judging whether overloading occurs or not, and if the overloading occurs, implementing a control operation associated with a cell individual offset (CIO), where the control operation associated with the CIO is used to cause at least one user terminal currently served by the target base station to select one base station as a service base station, and the base station selected by the user terminal is a base station except the target base station in the first type of base stations and the second type of base stations.

Description

technical field [0001] The present invention relates to the communication field, in particular to a load balancing method and device among base stations in a heterogeneous network. Background technique [0002] HetNet (Heterogeneous Network, heterogeneous network) refers to adding LNB (Low Power NodeB, micro base station) to the macro cellular network formed by the original MNB (Macro NodeB, macro base station) and its service users. The power and other parameters of the two base stations are adaptively selected among the accessing MNB and LNB. Both MNB and LNB can serve as the user's service base station, and because LNB can serve as a supplement to MNB, share the burden of MNB, and fill the coverage blind area of ​​MNB, therefore, heterogeneous networks often have higher capacity and better coverage effect. [0003] In a traditional homogeneous network, the transmission power of each base station is the same, and the user selects the serving base station according to the ...

AI Technical Summary

Problems solved by technology

[0012] In order to solve the above problems, the present invention provides a method and device for load balancing between base stations in a heterogeneous network, by adjusting the CIO of a low-power base station in a heterogeneous network, to achieve load balancing between base stations in a heterogeneous network, Therefore, the problem that the load control technology in the prior art affects service performance or increases the unbalanced uplink and downlink in the heterogeneous network is avoided
