1. A method performed by a first terminal in a wireless communication system, the method comprising:
establishing a unicast link with a second terminal, wherein each of the first terminal and the second terminal has a plurality of application layer identifiers (IDs), and the unicast link supports a plurality of service types associated with a first pair between an application layer ID of the first terminal and an application layer ID of the second terminal;
identifying whether a second pair of application layer IDs associated with a service type for which a data transfer is to be initiated is identical to the first pair of application layer IDs; and
reusing the established unicast link with the second terminal to initiate the data transfer, based on the second pair of application layer IDs being identical to the first pair of application layer IDs.
