Method for proximity-based notification in wireless communication system, and device for same
The present invention discloses a proximity based notification method in a wireless communication system and a device for the same. In detail, a proximity based notification method in a wireless communication system supporting device to device communication (D2D) may include the steps of: configuring, by a first terminal, a list of terminals which participate in an notification service and a notification time; broadcasting, by the first terminal, a discovery signal including a first D2D ID on a physical sidelink discovery channel (PSDCH) when the notification time arrives; and outputting, by the first terminal, a notification for notifying that a second terminal is proximate when the first terminal receives a second discovery signal including a second D2D ID from the second terminal included in the terminal list on the PSDCH.
1. A proximity based notification method in a wireless communication system supporting device to device (D2D) communication, the method comprising:
configuring, by a first terminal, a list of terminals which participate in a notification service and a notification time;
broadcasting, by the first terminal, a discovery signal including a first D2D ID on a physical sidelink discovery channel (PSDCH) when the notification time arrives;
outputting, by the first terminal, a notification for notifying that a second terminal is proximate when the first terminal receives a second discovery signal including a second D2D ID from the second terminal included in the terminal list on the PSDCH;
transmitting, by the first terminal, a notification service use agreement request message for requesting participation in the notification service to the second terminal;
receiving, by the first terminal, the first D2D ID and the second D2D ID from a D2D ID management server; and
returning, by the first terminal, the first D2D ID to the D2D ID management server.
