摘要
A network node initiates a MBMS session providing a multimedia service through a RAN to UEs using a FEC operation providing an initial FEC level, where the multimedia service is concurrently provided through unicast sessions. Feedback reports received from the UEs identify UEs consuming the multimedia service through the MBMS session and identify UEs consuming the multimedia service through the unicast sessions. A ratio is determined of a number of the UEs identified as consuming the multimedia service through the MBMS session to a number of the UEs identified as consuming the multimedia service through the unicast sessions. Responsive to determining that the ratio is less than a target ratio, the FEC level provided by the FEC operation is increased. Responsive to determining that the ratio is greater than the target ratio by a defined margin value, the FEC level provided by the FEC operation is decreased.
