Load balancing algorithm and system of heterogeneous network

Abstract

The invention discloses a load balancing algorithm of a heterogeneous network. The load balancing algorithm comprises the following steps: computing a network load degree of each network in a network group, judging whether a difference value between the maximum network load degree and the minimum network load degree is less than a first threshold value; if not, determining the number S of user terminals needing to adjust in the network with the maximum network load degree, and selecting S to-be-adjusted user terminals according to a preset rule, wherein the network load degree of the located network of the to-be-adjusted user terminal is greater than that of a to-be-accessed network; switching S to-be-adjusted user terminals to the to-be-accessed network so as to realize the load balancing of each network in the network group. By using the load balancing algorithm disclosed by the invention, multiple user terminals can be switched to the to-be-accessed network through once adjusting to realize the load balancing of each network in the network group; the regulating rate is improved, and the user experience is enhanced. The invention further discloses a load balancing system of the heterogeneous network with the above-mentioned effects.

Description

technical field [0001] The invention relates to the field of wireless heterogeneous network fusion, in particular to a load balancing algorithm and system of a heterogeneous network. Background technique [0002] The ever-evolving network applications have produced huge business volume and various types of business requirements. Different wireless access technologies have their own characteristics. In a certain area, each network forms a network group to provide high-quality wireless access for user terminals. Therefore, the integration of wireless heterogeneous networks is an inevitable trend, but in communication hotspot areas, heterogeneous network loads may be uneven, causing problems such as network congestion and call blocking to user terminals. The load balance of the network in the whole area is realized by adjusting the number of user terminals served by each network. [0003] In the prior art, a certain user terminal in the network with the largest network load is...

Problems solved by technology

However, in large-scale user scenarios, heterogeneous network load balancing is achieved by adjusting the access of a single user terminal, and the adjustment rate is too slow, which will reduce user experience
