Abstract

A plurality of telecommunication terminal (TD1, TD2, TDN) in a same coverage zone (CL) are served by at least one serving node (BS) in a telecommunication network infrastructure. Each telecommunication terminal (TD1, TD2, TDN) requests a specific data content (VC1, VC2, VCN). A scheduling method for data streaming in the telecommunication network infrastructure comprises: - estimating a capacity (C n,j ) of the at least one serving node (BS) with respect to each telecommunication terminal (n, TD1, TD2, TDN), - estimating a state of a plurality of data transmission buffer (B n,j , B1, B2, BN), - calculating at least one parameter (QP n,j , ± n,j ) based on said estimated capacity (C n,j ) and said data transmission buffer state (B n,j , B1, B2, BN) that minimize a data distortion (D n,j ) of each data stream (VS1, VS2, VSN) received by each telecommunication terminal (TD1, TD2, TDN) and maintain a number of data frames stored in each data transmission buffer (B n,j , B1, B2, BN) at a reference number of frames ( 0 ), - transcoding or filtering each data content at an output rate (R S n,j ) based on said parameter (QP n,j , ± n,j ), and storing each transcoded or filtered data content (VC1, VC2, VCN) as data frames into each data transmission buffer (B n,j , B1, B2, BN), - allocating an amount of bandwidth (W n,j ) to each telecommunication terminal (n, TD1, TD2, TDN) based on said parameter (QP n,j , ± n,j ), and - scheduling and transmitting each data frames as data streams (VS1, VS2, VSN) to each telecommunication terminal (n, TD1, TD2, TDN).
