Method and apparatus for establishing device-to-device connection in wireless communication system

A method for establishing, by a first device, a device-to-device (D2D) connection with a second device in a wireless communication system, the method comprising:

• determining whether to establish the D2D connection with the second device or not, based on at least one of a proximity between the first device and the second device based on a profile of the second device obtained through a neighbor discovery procedure, a presence of data to be transmitted to the second device, and a preference for the D2D connection of the first device;
• transmitting a connection establishment request message to request of the D2D connection establishment to the second device if it is determined to establish the D2D connection with the second device;
• receiving a connection establishment response message indicating whether the request of the D2D connection establishment is accepted or rejected, from the second device;
• transmitting a connection establishment confirm message to the second device if the request of the D2D connection establishment is accepted by the second device;
• and
• transmitting a connection establishment setup report message to a network.
