QoS THE METHOD AND APPARATUS OF APPLICATION AWARE QOS DIFFERENTIATED DEVICE-TO-DEVICE DISCOVERY IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a device-to-device (D2D: device-to-device) communication method and a device thereof, wherein the terminal to device communication method according to an embodiment of the present invention includes identification information of a discovery service and Transmitting a discovery registration request message including interest information to a base station; receiving a discovery registration response message including discovery resource information allocated according to identification information of the discovery service from the base station; And transmitting a discovery signal using the allocated discovery resource. According to an embodiment of the present invention, it ensures differentiated QoS according to the service of an application used by various users, can perform an independent discovery process from data communication, and manages interference under simultaneous access with a cellular user. (interference management).
