Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Technical scheme of the present invention is as follows:

[0028] ● Case 1: The base station schedules users accessing the wireless mobile network.

[0029] Step 1: The base station obtains the current status information of the channel where each user accessing the network is located, and calculates the time that the data in the buffer of the receiving end of each user can still be played (see the calculation of the playback buffer time of the user for specific steps), using These two pieces of information calculate the priority of each user, and the priority calculation is shown in formula (1), where R i (t) is the instantaneous data rate currently available to user i, t Bi (t) is the playback time supported by the data in the playback cache of the user i terminal. Go to step 2;

[0030] P i = ...

Abstract

The invention provides a scheduling method ensuring user quality of experience (QoE) performance in an HSPDA system. A scheduling device located in a base station utilizes detected information channel transmission quality of current users and surplus data quantity stored in buffer mode after playing in a user terminal to calculate priority of the current users and accordingly schedule the user with highest priority. The scheduling method ensures that the priority of a real-time business user is higher than the priority of a non-real-time business user in a network where real-time business and non-real-time business coexist, ensures requirements of the real-time business for delay and throughput capacity, and ensures the QoE of the users when the users watch videos.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for transmitting real-time services. Background technique [0002] In the third generation of mobile communication services, streaming media services are receiving more and more attention. In a large-scale streaming media system, most of the user's on-demand programs are concentrated in a few popular streaming media programs, which makes it imperative to merge user services, share streaming media servers and network bandwidth resources. While satisfying users' viewing requests, operators are also constantly considering improving users' comprehensive subjective experience of service quality and performance, that is, user experience (Quality of Experience, QoE) defined from the perspective of service application comfort. Through QoE scoring, operators can integrate users' video service quality and performance to optimize network services. WCDMA (Wideband Code Division...
