NETWORK NODE AND METHOD FOR HANDLING A PROCESS OF CONTROLLING A DATA TRANSFER RELATED TO VIDEO DATA OF A VIDEO STREAMING SERVICE

摘要

A method in a network node relating to a process of controlling a data transfer related to video data of a video streaming service from a server to a wireless device is provided. The network node and wireless device operates in a wireless communications network. The network node determines (403) a scheduling weight value for the wireless device to be used in the data transfer, based on a target rate scheduling weight value and a proportional rate fair weight value. The network node then determines (404) a size of data segment to be used in the data transfer based on at least part of the scheduling weight value. The network node further determines (405)a pending data volume for the transferring of the video data to a play back buffer of the wireless device based on at least part of the scheduling weight value.
