Embodiment Construction

[0040] Embodiments herein relate to the process of controlling the transfer of data related to video data for a video streaming service from a server to a wireless device. Embodiments herein provide solutions that combine characteristics of the HAS service (e.g., client behavior) with the RAN, and may include four control elements: outer and inner rate control loops, segment size control, and pending video control, which Both can be connected to existing RAN control functions.

[0041] image 3 A wireless communication network 100 is shown in which embodiments herein may be implemented. The wireless communication network 100 is a radio network such as LTE, WCDMA, Wimax, WiFi, Wireless Local Area Network (WLAN) or any radio network or system.

[0042] A number of network nodes operate in the wireless communication network 100, for simplicity, image 3 Only one network node 110 is shown in . A network node 110 may be referred to as a transmission point, and in some embodimen...

Abstract

A method in a network node involved in controlling a process of data transfer related to video data of a video streaming service from a server to a wireless device is provided. Network nodes and wireless devices operate in a wireless communication network. The network node determines (403) a scheduling weight value for the wireless device to use in data transmission based on the target rate scheduling weight value and the proportional rate fair weight value. The network node then determines (404) the size of the data segment to use in the data transfer based on at least a portion of the scheduling weight value. The network node also determines (405) an amount of data pending for transmitting video data to a playback buffer of the wireless device based on at least a portion of the scheduling weight value.

Description

technical field [0001] Embodiments herein relate to network nodes and methods therein. In particular, it relates to the process of handling control of data transfer related to video data for a video streaming service from a server to a wireless device. Background technique [0002] A wireless device for communication such as a terminal is also referred to as eg User Equipment (UE), mobile terminal, wireless terminal and / or mobile station. A wireless device is enabled to communicate wirelessly in a cellular communication network or wireless communication system (sometimes also called a cellular radio system or cellular network). The communication may be via the radio access network (RAN) and possibly one or more core networks comprised in the cellular communication network, for example between two wireless devices, between a wireless device and a conventional telephone and / or between a wireless device Execute with a server (such as a server that provides video streaming ser...
