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

摘要

A method and apparatus for establishing, by a first device, a device-to-device (D2D) connection with a second device in a wireless communication system is provided. When the D2D connection is initiated by a network, the first device receives a D2D broadcast configuration message including information on the second device, from the network, and determines whether to establish the D2D connection with the second device or not. Or, when the D2D connection is initiated by the first device, the first device determines 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.

1. 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:
receiving a D2D broadcast configuration message including information on the second device, from a network; 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, a presence of data to be transmitted between the first device and the second device, and a preference for the D2D connection of the first device; and transmitting a connection establishment setup report message including information on the second device to the network, if it is determined to establish the D2D connection with the second device, wherein the D2D broadcast configuration message further includes a D2D identifier, and wherein the D2D identifier is a link level D2D identifier allocated to a physical link between the first device and the second device.
