The invention relates to error control for point-to-multipoint (PTM) transmissions of content data over a radio interface. A method embodiment for controlling a PTM transmission in a PTM-enabled network comprises the steps of receiving and storing redundancy data at a dedicated redundancy data storage in a radio access network, wherein the redundancy data are provided for a correction of transmission errors in the content data resulting from the transmission of the content data without the redundancy data over one or more radio interfaces; receiving a request for redundancy data from a redundancy data control node; and responding to the redundancy data request by providing at least a portion of the redundancy data.
