Abstract

The invention discloses a video cross-layer scheduling method of a mobile communication system on the basis of QoE prediction. The method comprises the steps of: utilizing a clustering analysis method to divide videos into a slight motion, common scene switching and fast motion by content characteristics according to speed change parameter and brightness parameter of the videos; carrying out cross-layer analysis on a user application layer, network layer parameters and video content type information, and respectively establishing three user-received video quality prediction models by artificial nerve network studying method; and according to a model prediction result and a target function requirement for user-received video quality of the maximization system, adopting a PSO (Particle Swarm Optimization) algorithm to carry out the resource scheduling and distribution. Due to adoption of the technical scheme, the problem that the resource utilization ratio is low and the subjective perception effect of the user to the video quality is not fully considered in the existing mobile communication system video services can be solved, and the cross-layer resource scheduling of the video services based on a QoE evaluation method is realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, and is a technical scheme for implementing cross-layer resource scheduling of video transmission services based on a QoE evaluation method in a next-generation mobile communication system (IMT-Advanced) and realizing the optimization of subjective quality evaluation of system users. Background technique [0002] With the globalization of 3G network deployment and the gradual maturity of the operation mode, the standard formulation and key technology research of the next generation mobile communication system IMT-Advanced are increasingly concerned. ITU believes that the IMT-Advanced system (4G) has new capabilities beyond IMT-2000, and can provide users with fast data access, unified information and various broadband multimedia services in a more innovative and interactive service form, and the service pays more attention to participation , interactivity, and pay more attention to th...
