A method for supporting Device-to-Device (D2D) communications by a Mobile Station (MS) in a communication system is provided. The method includes performing a network entry procedure with a Base Station (BS) and receiving, from the BS, a BS prefix, a temporary Identifier (ID), and a valid period timer value for the temporary ID, generating a device ID using the BS prefix and the temporary ID, and performing, upon detecting data to be transmitted, communication with a peer MS using the device ID for a time indicated by the valid period timer value. The BS prefix is information unique within the communication system, and the temporary ID is information unique within a coverage area of the BS. 1. A method for supporting Device-to-Device (D2D) communications by a Mobile Station (MS) in a communication system , the method comprising:performing a network entry procedure with a Base Station (BS) and receiving, from the BS, a BS prefix, a temporary Identifier (ID), and a valid period timer value for the temporary ID;generating a device ID using the BS prefix and the temporary ID; andperforming, upon detecting data to be transmitted, communication with a peer MS using the device ID for a time indicated by the valid period timer value,wherein the BS prefix is information unique within the communication system, and the temporary ID is information unique within a coverage area of the BS.2. The method of claim 1 , further comprising:upon request for handover from the BS to a neighbor BS, transmitting the device ID to the neighbor BS;receiving, from the neighbor BS, a neighbor BS's prefix, a neighbor BS's temporary ID, and a valid period timer value for the neighbor BS's temporary ID;generating a new device ID using the neighbor BS's prefix and the neighbor BS's temporary ID; andperforming, upon detecting data to be transmitted, communication with a peer MS using the new device ID for a time indicated by the valid period timer value for the neighbor BS's temporary ID.3.
