A method for transferring a flow of data from a first base station to a mobile terminal in a wireless cellular telecommunication network, the first base station and the mobile terminal being linked through a radio channel, the method comprising: - splitting the flow of data in at least two splits, - transferring a first split from the first base station to the mobile terminal through the radio channel, - transferring at least a second split (FL2a,FL2b;FL3a,FL3b) from the first base station to the mobile terminal via at least a second base station (BS2;BS3) of the wireless cellular telecommunication network, - receiving, from the mobile terminal, a measurement report on signals transferred by plural base stations of the wireless cellular telecommunication network, - determining (S601,S620), from the measurement report, if the flow of data has to be split in a more important or less important number of splits, characterized in that the method is executed by the first base station and in that the method further comprises, when the first base station has determined that the flow of data has to be split in a less important number of splits: - splitting the flow of data into a reduced number of splits; - stopping transmitting data of said flow to one second base station which transferred signals for which the measurement report indicates a measurement quality lower than a given threshold; - transmitting to said one second base station a message representative of a request to release a link between the first base station and said one second base station, - receiving from said one second base station data, if any, transferred through a radio channel between said one second base station and the mobile terminal and which have not been acknowledged by the mobile terminal, and - transferring the received data to the mobile terminal. - splitting the flow of data in at least two splits, - transferring a first split from the first base station to the mobile terminal through the radio channel, - transferring at least a second split (FL2a,FL2b;FL3a,FL3b) from the first base station to the mobile terminal via at least a second base station (BS2;BS3) of the wireless cellular telecommunication network, - receiving, from the mobile terminal, a measurement report on signals transferred by plural base stations of the wireless cellular telecommunication network, - determining (S601,S620), from the measurement report, if the flow of data has to be split in a more important or less important number of splits, - splitting the flow of data into a reduced number of splits; - stopping transmitting data of said flow to one second base station which transferred signals for which the measurement report indicates a measurement quality lower than a given threshold; - transmitting to said one second base station a message representative of a request to release a link between the first base station and said one second base station, - receiving from said one second base station data, if any, transferred through a radio channel between said one second base station and the mobile terminal and which have not been acknowledged by the mobile terminal, and - transferring the received data to the mobile terminal.
