A Resource Scheduling Method Based on Content Awareness

Abstract

The invention discloses a resource scheduling method based on content awareness, which includes the steps of: the transmitting end counts the content ID and related channel state information requested by each receiving end; The number of users who can satisfy the current service request with different coding and modulation methods under the request content; the transmitting end calculates the number of users currently scheduling a certain content with a certain coding and modulation method according to the predicted future popularity of the content, the user cache status and the number of connections within the coverage area The number of potential service users in the future, and the number of potential service users is added to the scheduling weight; the content is sorted according to the scheduling weight, and the content is sent from high to low according to the scheduling weight according to the preset coding and modulation method; the receiving end receives and decodes For air interface data, for users with good channels who have not sent requests, high-interest content on the air interface can be selectively cached. The present invention realizes the maximum expected return under resource consumption per unit when scheduling resources. Since users with good channels can cache, repeated transmission of hot content is avoided, the transmission efficiency of content is improved, and a better experience is brought to users.

Description

technical field [0001] The invention relates to the field of resource scheduling in wireless communication, in particular to a resource scheduling method based on content awareness. Background technique [0002] With the ubiquity of mobile devices and the continuous enrichment of mobile applications, users' demand for mobile data is showing explosive growth, which has brought great challenges to network operators. The demand for massive data is mainly concentrated on multimedia content. It is predicted that multimedia content transmission will account for 72% of data traffic in 2019. Unlike voice calls or peer-to-peer SMS services, multimedia content has distinct popularity attributes, that is, the same multimedia content can be requested by multiple users. According to statistics, although the traffic of multimedia content requested by users is huge, most of the user requests are actually concentrated on a small part of high-interest content, and this part of content can b...

[0004] In the prior art, it has been considered to use the content popularity attribute for scheduling in the broadcast push service, but because it is a broadcast push service rather than a real-time scheduling service, it cannot use the physical layer channel information requested by the user in real time to associate with the content attribute.
