Abstract
A method and device for a relay User Equipment (UE) are disclosed. The relay UE receives a first direct communication request message from a source end UE for establishing a UE-to-UE (U2U) relay communication with a target end UE. The relay UE also sends a second direct communication request message to the target end UE in a direct link establishment procedure used for establishing a direct link for supporting the U2U relay communication. The relay UE further receives a direct communication security request message from the target end UE for triggering the relay UE to perform a key request procedure with a network. In addition, the relay UE sends a direct communication security reject message to the target end UE if the key request procedure with the network fails. Furthermore, the relay UE aborts the direct link establishment procedure after sending the direct communication security reject message.
