1. A method performed by a first terminal in a communication system, the method comprising:
performing data communication with a second terminal over a proximity service (ProSe) path;
identifying a signal strength of the ProSe path;
determining a path switching from the ProSe path to a 5th generation core network (5GC) path based on the signal strength of the ProSe path;
determining first 5GC path quality of service (Qos) parameters of the first terminal and second 5GC path QoS parameters of the second terminal;
transmitting, to the second terminal, a path switching request message including the second 5GC path QoS parameters;
performing modification of a packet data unit (PDU) session based on the first 5GC path QoS parameters; and
performing the data communication with the second terminal over the 5GC path.
