There is proposed a mechanism for controlling a radio link failure recovery procedure in a communication network having relay nodes, wherein a network control node, such as a DeNB, forwards cached UE context information to a target network node which is contacted by an UE for re-establishment after radio link failure and requests, since it does not have the context information, the context information for the UE in question. Context information can also be proactively forwarded from the network control node to candidate neighboring network nodes when it is detected that a radio link failure between a relay node and the network control node, or between the relay node and a UE is possible.
