The application relates to a UE, which is the initiator, that needs to communicate with another UE, which is the target, and which is not in proximity. Then the initiator tries to communicate with the target via a UE-to-UE Relay. Solutions for this problem are discussed e.g. in 3GPP TR 23.713, passage 7.3 and corresponding submissions to work items ProSe/Rel-12 and ProSe/Rel-13.The application in particular proposes that Layer-3 relaying is being used, whereby IP addresses of the respective UEs are assigned and exchanged (312, 314) such that IP communication between the initiator (102) and the target (106) can be performed (320) via the UE-to-UE Relay (104). |
