Abstract
In response to a radio link failure between given user equipment and a source access node of a communication system during a data transfer operation over a control plane, a method is provided for recovering the radio link for the given user equipment through a target access node of the communication system. The radio link recovery is enabled via a mobility management node of the communication system using a non-access stratum security context previously established between the given user equipment and the mobility management node.
