    摘要: Provided is a method performed by a terminal of performing communication, the method including generating a private call setup request message including a call identifier information element (IE), a caller IE, a callee IE, and a call type IE set to an emergency private call, based on receiving a user indication to upgrade a call to emergency call, wherein the terminal is in an in-progress private call state; setting a proximity-based services (ProSe) per-packet priority corresponding to the emergency private call; transmitting, to another terminal, the private call setup request message; starting a timer relating to private call request retransmission based on the emergency call setup request message; and entering an in-progress emergency private call state from the in-progress private call state.
