Abstract
The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting a more increased rate beyond a 4th-Generation (4G) system and a technology for Internet of Things (IoT). The disclosure can be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, networked car, health care, digital education, smart retail, security and safety services. A method of a first terminal in a wireless communication system is provided. The method includes establishing a unicast link with a second terminal; determining to change a first old identifier of the first terminal related to the unicast link to a first new identifier of the first terminal; transmitting, to the second terminal, a link identifier (ID) update request message including the first new identifier by using the first old identifier and a second old identifier of the second terminal; receiving, from the second terminal, a link ID update accept message including a second new identifier of the second terminal changed from the second old identifier and the first new identifier by using the first old identifier and the second old identifier in response to the link ID update request message; and transmitting, to the second terminal, a link ID update confirmation message including the second new identifier.
