Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0032] refer to figure 1 , the application scenario of the present invention is long-term evolution LTE network downlink resource allocation, assuming that the spectrum bandwidth of the cell is 10MHz, and the number of schedulable resource blocks RB is N, at a certain scheduling time, there are U online video users in the cell to receive services, Each user only generates one kind of business. By adding a video service QoE information collection module to the user equipment UE, the user sends its own buffer status level information and video QoE benefit function model coefficients to the base station, and the base station calculates user resource allocation priorities based on this. Since the network environment and video service content change in real time, when the channel quality is poor, the video is prone to freezing, affecting user experience. The user's b...

Abstract

The present invention relates to an LTE network video service QoE guarantee resource allocation method, which is characterized in that: comprising the following steps: 1) the base station eNodeB receives the feedback information of each video user from the user equipment UE; 2) the base station eNodeB monitors its radio link control RLC cache queue 3) The scheduler in the base station eNodeB calculates the QoE benefit function value based on the satisfaction Q(R) obtained when the video user rate requirement R is reached; 4) The scheduler combines Construct the video QoE benefit function and the terminal buffer state level to allocate the user's priority on N resource blocks at time t , where u and n represent user and resource block RB indexes respectively; 5) The resource allocation priority constructed according to step (4) Size, prioritize users, and allocate time-frequency resource blocks to users in round robin. The method of the present invention guarantees the user's service experience quality from two aspects of the video picture quality and the fluency of the playing process.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method for allocating downlink resources in a long-term evolution (LTE) network aiming at guaranteeing the quality of experience (QoE) of online video services, specifically a method for allocating resources for guaranteeing QoE of video services on an LTE network. Background technique [0002] Compared with 2G / 3G technology, 3G Long Term Evolution (LTE) system can provide higher data rate and better network performance, and has received extensive attention in recent years. The growth of mobile communication network bandwidth is not synchronous with the increase of business demand, so business characteristics and user expectations should be fully considered when allocating resources. Video services will occupy the largest proportion in mobile multimedia services, and it is very necessary to ensure the quality of service experience of video streaming users. [00...
