D2D communication method according to D2D service type as well as D2D application type, and apparatus for same
First Claim
1. A method of performing a communication by a first device-to-device (D2D) user equipment (UE) 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;
finding neighbor D2D UEs which are sharing a first ID with the first D2D UE 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 using the first ID, wherein the first ID is corresponding to the first D2D service type or the first D2D application type;
establishing a first connection with a second D2D UE using the first ID by selecting the second D2D UE from the found at least one or more neighbor D2D UEs;
performing a D2D communication corresponding to the first D2D service type or the first D2D application type with the second D2D UE in accordance with the first connection;
checking whether the second D2D UE is sharing a second ID with the first D2D UE; and
establishing a second connection corresponding to a second D2D service type or a second D2D application type with the second D2D UE using the second ID without finding another D2D UE while maintaining the first connection, if the second D2D UE is sharing the second ID with the first D2D UE,wherein the second ID is corresponding to the second D2D service type or the second D2D application type.

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 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 D2D service type or a first D2D application type to be executed on the basis of 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.

6. A first device-to-device (D2D) user equipment (UE) of performing a communication in a wireless communication system supportive of a D2D (device-to-device) communication, the first D2D UE 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 find neighbor D2D UEs which are sharing a first ID 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 using the first ID, wherein the first ID is corresponding to the first D2D service type or the first D2D application type, the processor configured to establish a first connection with a second D2 UE using the first ID by selecting the second D2D UE from the found at least one or more neighbor D2D UEs, the processor configured to perform a D2D communication corresponding to the first D2D service type or the first D2D application type to be performed with the second D2D UE in accordance with the first connection, the processor configured to check whether the second D2D UE is sharing a second ID with the first D2D UE, the processor configured to establish a second connection corresponding to a second D2D service type or a second D2D application type with the second D2D UE using second ID without finding another D2D UE while maintaining the first connection, wherein the second ID is corresponding to the second D2D service type or the second D2D application type.
