An operating method of a Mobile Station (MS) for providing connectivity of Peer-to-Peer (P2P) communications in a mobile communication system, the method comprising: establishing, by the MS, a direct P2P communication with a correspondent MS in a service coverage area of a first Base Station (BS); maintaining, by the MS, the established direct P2P communication with the correspondent MS without an intervention of the first BS; determining, by the MS, whether the established direct P2P communication is no longer feasible with the correspondent MS during the established direct P2P communication; when the direct P2P communication is no longer feasible, transmitting, by the MS, a P2P connection request message for requesting a relay of the established direct P2P communication, directly to the first BS; receiving, by the MS, a P2P connection response message in response to the P2P connection request message, directly from the first BS; and maintaining, by the MS, a P2P data communication of the established direct P2P communication with the correspondent MS via the first BS based on the receipt of the P2P connection response message, wherein the P2P connection request message comprises at least one of a P2P network identifier, P2P resource information, or a P2P service type.
