METHOD AND APPARATUS FOR ESTABLISHING DEVICE-TO-DEVICE CONNECTION IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for establishing, by a network, a device-to-device (D2D) connection in a wireless communication system, the method comprising:
- determining whether to establish the D2D connection between devices based on at least one of a proximity between the devices, a presence of data to be transmitted by the devices, and a preference for the D2D connection of the devices;
transmitting a connection establishment request message to request of the D2D connection establishment to a first device and a second device, the connection establishment request message including at least one of a connection establishment type, a quality of service (QoS) parameter for the D2D connection, and security information;
receiving a connection establishment response message indicating whether to accept the request of the D2D connection establishment from the first device and the second device; and
transmitting a connection establishment confirm message to confirm the D2D connection establishment to a first device and a second device.

Abstract
A method and apparatus for establishing a device-to-device (D2D) connection in a wireless communication system is provided. A network transmits a connection establishment request message to request of the D2D connection establishment to a first device and a second device, receives a connection establishment response message indicating whether to accept the request of the D2D connection establishment from the first device and the second device, and transmits a connection establishment confirm message to confirm the D2D connection establishment to a first device and a second device. The connection establishment request message includes at least one of a connection establishment type, a quality of (QoS) parameter for the D2D connection, and security information.

11. A method for transmitting, by a first device, data in a wireless communication system, the method comprising:
-
receiving a connection establishment request message to request of a device-to-device (D2D) connection establishment from a network, the connection establishment request message including at least one of a connection establishment type, a quality of service (QoS) parameter for the D2D connection, and security information; transmitting a connection establishment response message indicating whether to accept the request of the D2D connection establishment to the network; receiving a connection establishment confirm message to confirm the D2D connection establishment from the network; allocating resources for transmission of data to the second device; and transmitting the data to the second device.

12. A method for establishing, by a network, a device-to-device (D2D) connection in a wireless communication system, the method comprising:
-
determining whether to establish the D2D connection between devices based on at least one of a proximity between the devices, a presence of data to be transmitted by the devices, and a preference for the D2D connection of the devices; transmitting a D2D broadcast configuration message to request of the D2D connection establishment to a plurality of source devices, the D2D broadcast configuration message including at least one of information on the plurality of source devices and a target device, D2D connection information pre-established for the target device, a quality of service (QoS) parameter for the D2D connection, security information, and a D2D identifier; and receiving a connection establishment setup report message including information on the plurality of source devices and the target device from the plurality of source devices. - View Dependent Claims (13, 14)
