摘要

Methods for D2D connection re-establishment and related user equipments and radio access node are disclosed, wherein the D2D connection is established between a first user equipment and a second user equipment under the control of a radio access node. In one embodiment, the method comprises: receiving, by the first user equipments, a first message from the second user equipments, the first message comprising a first credential which is calculated by the second user equipment; verifying the first credential by the first user equipment; and sending a second message indicating acknowledgement of the D2D connection re-establishment from the first user equipment to the second user equipment upon successful verification of the first credential.
