Data scheduling method and access network equipment

Abstract

The invention provides a data scheduling method and access network equipment and aims to correct the scheduling information of a present grid according to the historical grid information and predict a grid path and a channel state so as to select a reasonable air interface resource distribution strategy to send the data to a user so that the user is made to acquire enough data to improve network experience of the user. The method comprises steps that a wireless grid is established, and the grid path information of the wireless grid and the historical grid information of each wireless grid are acquired; a present grid of a target user is determined, and the scheduling information of the present grid is acquired; the scheduling information of the present grid is corrected according to the historical grid information of the present grid and preset optimization rules; a grid path and the target data volume are predicted; a channel state of each wireless grid of the grid path is predicted according to the grid path and the historical grid information; the air interface resource distribution strategy is determined according to the target data volume and the channel state of each wireless grid of the grid path.

Description

technical field [0001] The present application relates to the communication field, in particular to a data scheduling method and access network equipment. Background technique [0002] In high-speed scenarios such as high-speed rail, it has become a rigid demand for users to use the user's Internet service and video service. For example, the current mainstream video service uses a video data download mechanism that is broadcast while downloading, that is, downloading part of the video data first, and then waiting for the part of the video When the data is gradually consumed, the subsequent video data will be downloaded to ensure the smoothness of the video. However, in the wireless communication network under the high-speed rail scenario, because the high-speed rail has the characteristics of fast speed, the user's movement speed is also very fast. Compared with other scenarios, the user's wireless channel quality changes faster, and the user The frequency of switching also...

Problems solved by technology

[0004] However, in prior art 1, since the channel quality changes rapidly in high-speed motion scenarios, the channel quality measurement reported by the user during scheduling can no longer represent the channel quality at the scheduling time, and the MCS order selection does not match the current channel quality. Severely slows down the data sending rate

If the selected MCS order is low and the data transmission rate is low when the channel condition is good, air interface resources will be wasted to a certain extent.

If the selected MCS order is high when the channel condition is poor, the error rate of data transmission will increase, resulting in a low data transmission rate; while existing technology 2 effectively considers the fairness among users, but in the high-speed motion scene In this case, when the video user is in a position with a good channel, since this policy limits the maximum air interface resource share that the video user can allocate, the video user cannot use the good channel conditions to cache as much data as possible to cope with the subsequent deterioration. channel, it may still cause playback freezes due to insufficient cached video data when the channel becomes poor, which affects the user's network experience
