Abstract

A device-to-device (D2D) terminal for communicating in a wireless communication system supporting D2D communication includes: a receiver configured to receive information for setting the D2D searching interval corresponding to a D2D service type or a D2D application type from a base station; and a processor configured to search an neighbor D2D terminal in a D2D searching interval corresponding to a first D2D service type or a first D2D application type to be executed based on the information for setting the D2D searching interval, to select any one D2D terminal from among the one or more searched neighbor D2D terminals in order to set a connection corresponding to the first D2D service type or the first D2D application type, and to control the D2D communication corresponding to the first D2D service type or the first D2D application type with the selected D2D terminal according to the connection.

Claims

1. A method of performing a communication by a device-to-device (D2D) user equipment in a wireless communication system supportive of a D2D communication, the method comprising:

receiving a D2D discovery interval configuration information corresponding to a D2D service type or a D2D application type each from a base station;

searching for neighbor D2D user equipments in a D2D discovery interval corresponding to a first D2D service type or a first D2D application type to enable based on the D2D discovery interval configuration information;

establishing a connection corresponding to the first D2D service type or the first D2D application type by selecting a prescribed D2D user equipment from the found at least one or more neighbor D2D user equipments; and

performing the D2D communication corresponding to the first D2D service type or the first D2D application type with the selected D2D user equipment in accordance with the connection.

2. The method of claim 1, further comprising establishing a connection corresponding to a second D2D service type or a second D2D application type with the selected D2D user equipment, wherein when the connection corresponding to the second D2D service type or the second D2D application type with the selected D2D user equipment is configured, a discovery of the D2D discovery interval is skipped.

3. The method of claim 1, further comprising the step of establishing a connection corresponding to a second D2D service type or a second D2D application type with the selected D2D user equipment, wherein an identifier in accordance with the connection established for the second D2D service type or the second D2D application type is set to be identifiable from an identifier in accordance with the connection established for the first D2D service type or the first D2D application type.

4. The method of claim 1, wherein a period or length of the D2D discovery interval is different per the D2D service type or the D2D application type.

5. The method of claim 1, wherein the D2D discovery interval includes a discovery region corresponding to a plurality of D2D service types or a plurality of D2D application type and wherein a D2D discovery region corresponding to the first D2D service type or the first D2D application type in the D2D discovery interval is searched.

6. The method of claim 1, wherein the D2D discovery interval corresponding to the first D2D service type or the first D2D application type is located across at least two D2D discovery intervals.

7. The method of claim 1, further comprising transmitting a D2D discovery signal in the D2D discovery interval corresponding to the D2D service type or the D2D application type supported by the D2D user equipment.

8. A device-to-device (D2D) user equipment of performing a communication in a wireless communication system supportive of a D2D (device-to-device) communication, the D2D user equipment comprising:

a receiver configured to receive a D2D discovery interval configuration information corresponding to a D2D service type or a D2D application type each from a base station;

a processor configured to search for neighbor D2D user equipments in a D2D discovery interval corresponding to a first D2D service type or a first D2D application type to enable based on the D2D discovery interval configuration information, the processor configured to establish a connection corresponding to the first D2D service type or the first D2D application type by selecting a prescribed D2D user equipment from the found at least one or more neighbor D2D user equipments, the processor configured to control the D2D communication corresponding to the first D2D service type or the first D2D application type to be performed with the selected D2D user equipment in accordance with the connection.

9. The D2D user equipment of claim 8, wherein the processor is configured to establish a connection corresponding to a second D2D service type or a second D2D application type with the selected D2D user equipment and wherein when the connection corresponding to the second D2D service type or the second D2D application type with the selected D2D user equipment is configured, the processor controls a discovery of the D2D discovery interval to be skipped.

10. The D2D user equipment of claim 8, wherein the processor is configured to establish a connection corresponding to a second D2D service type or a second D2D application type with the selected D2D user equipment and wherein an identifier in accordance with the connection established for the second D2D service type or the second D2D application type is set by the processor to be identifiable from an identifier in accordance with the connection established for the first D2D service type or the first D2D application type.
