    Abstract: A method and apparatus for traffic safety are provided using vehicle driving-related information obtained on the basis of a transmission/reception beam pair of a road side unit (RSU) and a vehicle on-board unit (OBU), thereby reducing a probability that vehicle collisions occur where visual fields may be obscured. The method includes setting a path from a current location of the electronic device to a destination, and transmitting a message indicating an emergency situation to other devices located on the path while moving to the destination. The method further includes determining a transmission/reception beam pair of the electronic device and a road apparatus, using a reference signal received from the road apparatus, transmitting a signal including information for the transmission/reception beam pair to the road apparatus, and receiving, from the road apparatus, a message warning that the electronic device and another neighboring electronic device are approaching each other.

    Abstract: A method and apparatus for performing a state transition for Device to Device (D2D) communication are provided. The method includes determining whether D2D initiation is required, while a terminal is operating in a first or a second state defined by EPS (Enhanced Packet System) Mobility Management (EMM)-Deregistered and EPS Connection Management (ECM)-IDLE at a Non-Access Stratum (NAS) layer and Radio Resource Control (RRC)-IDLE. If the D2D initiation is required, the method includes transitioning to a third state defined by EMM-Registered and ECM/RRC-Connected and performing the D2D initiation through a mobile communication network. If a deactivation condition is satisfied or a D2D state update is completed in the third state, the method includes transitioning to a fourth state defined by EMM-Registered and ECM/RRC-IDLE, and if a state update or scheduling for D2D communication is required in the fourth state, the method includes transitioning to the third state.
