Abstract: This specification discloses a relay communication method and an apparatus, and relates to the field of communication technologies, to ensure security in a relay user equipment (relay UE) discovery process. The method includes: Second user equipment broadcasts a layer 2 (L2) identifier, and first user equipment receives the L2 identifier of the second user equipment, and reports the L2 identifier of the second user equipment and signal quality of the second user equipment to a first access network device. Alternatively, a radio network temporary identifier (RNTI) of second user equipment is sent to first user equipment through a unicast connection. In a relay UE discovery process, leakage of a UE RNTI is avoided, and security of relay UE is ensured.
