Abstract: One embodiment of the present specification provides a method for selecting or reselecting a relay for a proximity service. The method comprises the steps of: receiving, by user equipment (UE) which is to receive a relay service, synchronization signals from a plurality of other UEs capable of operating as relays; and receiving, by the UE, announce messages from the plurality of other UEs capable of operating as the relays. Here, the announce messages from each of the other UEs can contain relay type information on whether to support a UE-to-network relay service, packet data network (PDN)/access point name (APN) information, and service/group information. The method further comprises the steps of: generating, by the UE, a candidate relay list on the basis of the relay type information, the PDN/APN information, and the service/group information within the announce messages received from the plurality of other UEs; and selecting or reselecting, by the UE, one of the other UEs within the candidate relay list in consideration of relay type, PDN/APN, and service/group information necessary for a service of the UE.
