Patent ID: 8386900

Claim:
A method for controlling a point-to-multipoint (PTM) transmission of content data in a PTM-enabled mobile network, comprising the following steps: receiving redundancy data at a dedicated redundancy data storage in a radio access network of the PTM-enabled mobile network over which the PTM transmission of the content data is performed, 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 defining cells of the radio access network; storing the received redundancy data in the redundancy data storage; 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; wherein the step of receiving the redundancy data includes receiving at least one of: a storage time value indicating a time span for storing the redundancy data in the redundancy data storage, and a duration time value indicating duration of the reception of the redundancy data.
