METHOD AND APPARATUS FOR ESTABLISHING DEVICE-TO-DEVICE CONNECTION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for establishing a device-to-device (D2D) connection in a wireless communication system is provided. A first device may establish the D2D connection with a second device. The first device only knows information on neighbor devices of the first device, and a network does not know the information on neighbor devices of 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, a presence of data to be transmitted to the second device, and a preference for the D2D connection of the first device.

主权项

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:
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 first connection establishment request message to request of the D2D connection establishment to a network if it is determined to establish the D2D connection with the second device; receiving a first connection establishment response message indicating whether the request of the D2D connection establishment is accepted or rejected, from the network; and requesting the D2D connection establishment to the second device if the request of the D2D connection establishment is accepted by the network.
