Abstract
A user equipment node, upon determining that the data loss in a requested file is above, or likely to be above a threshold value, transmits a delivery missing report to a server node indicating that the data loss in the requested file is above the threshold value. The delivery missing report is used by the server node for determining whether or not a multicast file repair procedure should be enabled, based on the number of delivery missing reports it has received from other user equipment nodes. This enables a point-to-multipoint file repair procedure to be enabled sooner, and prevent a flood of point-to-point file repairs.
