Embodiment Construction

[0019] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, it is a schematic diagram of a scene where the method of the present invention is applied, in which a mobile user moves within the coverage areas of several base stations. The method of the invention establishes a decision tree model in the process of predicting user mobility, studies and compares the influence of the user's previous state on future position prediction, selects the best input attribute characteristics of the decision tree, and improves the accuracy of mobility prediction. The present invention can predict the position of the user at the next moment by analyzing the mobility of the user and mining the rules therein. Secondly, in order to optimize the load balancing of the entire network by allocating reasonable resources to users, it is necessary to understand the load status of the target base statio...

Abstract

The invention provides a mobility prediction-based load balance optimization method applied to a heterogeneous network and belongs to the communication technical field. According to the method of thepresent invention, the influence of the previous state of a user on future position prediction is researched and compared; optimal decision tree input attribute features are selected, so that a decision tree model can be established to predict the position of the user at the next moment; a time series analysis method is adopted to predict the load status of a base station when the user arrives; and a resource allocation strategy is formulated in advance to optimize the load balance of a network. With the method of the invention adopted, the accuracy of mobility prediction can be improved; thepossible impact of each potential user in adjacent areas on the base station does not need to be monitored; and therefore, the burden of the network is reduced, the network performance of hot spot areas can be improved, and user service experience can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a load balancing optimization method based on mobility prediction in a heterogeneous network. Background technique [0002] With the rapid growth of mobile data traffic in communication networks, a large number of small base stations are widely deployed to increase network capacity. Some hotspots tend to gather more users than others. Due to the uneven distribution of users in the communication network, some base stations are overloaded due to too many users, and at the same time, other base stations are relatively idle with light loads. Users in hotspots may experience poor service experience because base stations cannot provide sufficient resources in a timely manner. In order to improve the service quality of users and make full use of the idle resources of base stations with lighter loads, it is necessary to use load balancing technology to adjust user connections and i...
