    Abstract: 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.

    Abstract: A method and an apparatus for performing direct communication with at least one other user equipment are provided. The method and apparatus comprises upon generation of an event requiring the direct communication, transmitting a floor request, monitoring whether a response to the floor request is received from at least one adjacent UE, if a response to the floor request is not received until the floor request is transmitted a predetermined number of times at a predetermined interval, determining that a transmission right for the direct communication is granted, and if it is determined that the transmission right is granted, transmitting a signal to the at least one other UE by the direct communication.

    Abstract: The present disclosure relates to technologies for sensor networks, machine-to-machine (M2M) communications, machine-type communications (MTC), and the Internet of Things (IoT). The present disclosure may be applied to intelligent services such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, and security and safety related services, on the basis of said technologies. More specifically, the present disclosure relates to a method for performing a group communication by a terminal, the method comprising the steps of: setting a condition for selecting target terminals which will perform a group communication on the basis of the position of the terminal, and transmitting, to a server for providing the group communication, configuration information including the set selection condition; transmitting, to the server, a request for the group communication; receiving, from the server, a talk burst control message for a group communication with terminals which satisfy the selection condition and are selected from adjacent terminals positioned in the near field of the terminal; and relaying and transmitting media data to the selected terminals via the server.

    Abstract: A method and an apparatus for performing direct communication with at least one other user equipment are provided. A method performed by a UE includes transmitting, to at least one other UE included in a group call with the UE, a first message requesting permission for transmission; starting a timer upon transmitting the first message; restarting the timer in response to the timer expiring before a second message in response to the first message has been received; stopping the timer in response to receiving the second message before the timer expires; retransmitting the first message each time the timer expires before receiving the second message until a total number of transmissions of the first message reaches a predetermined number of times; transmitting, to the at least one other UE, a third message indicating that the permission for transmission is granted to the UE after the first message is transmitted the predetermined number of times and the timer expires before receiving the second message; and transmitting media data to the at least one other UE after transmitting the third message.
