METHOD FOR PERFORMING A CHANGE OF MODE IN DEVICES DIRECTLY COMMUNICATING WITH EACH OTHER IN A WIRELESS CONNECTION SYSTEM, AND APPARATUS FOR SAME

摘要

The present invention relates to a method for performing a handover to a cellular network through which devices communicate with each other in a wireless connection system for supporting communication between the devices, and an apparatus for same. In an embodiment of the present invention, the method for performing a change of mode in a first device communicating with another device in the wireless connection system includes: a step of determining whether a mode change condition for performing a hand-over to a cellular network through which devices communicate with each other is satisfied; a step of transmitting a mode change instruction message to a base station when the mode change condition is satisfied; a step of receiving a mode change command message for starting a mode change from the base station; a step of transmitting a first data packet index with respect to a data packet transmitted to a second device at a final stage through the communication between the devices to the base station; a step of ending the communication with the second device when the inter-device communication end request message is received from the base station; and a step of transmitting data to the second device through the cellular network.
