METHOD AND APPARATUS FOR STARTING THE DEVICE TO DEVICE COMMUNICATION, METHOD AND APPARATUS FOR STOPPING THE DEVICE TO DEVICE COMMUNICATION |
摘要 |
PURPOSE: A D2D(Device to Device) communication starting and terminating method and a device thereof are provided to offer a detailed procedure between the devices by activating and setting a D2D bearer according to an RRC(Radio Resource Control) connection reconfiguration message of a base station. CONSTITUTION: When a D2D link is able to be set, a first and a second device(110,120) transmit a D2D connection inspection response message to a base station(210). The first and the second device sets a D2D bearer based on an RRC connection reconfiguration request message of the base station and transmits the RRC connection reconfiguration response message to the base station. The first and the second device activate a D2D bearer based on a D2D bearer activation request message of the base station and transmit the D2D bearer response message to the base station. [Reference numerals] (110) First device; (120) Second device; (210) First base station; (AA,S311) Response to D2D connection inspection; (BB) Send a message of D2D communication availability; (S301) Determine the availability of D2D communication; (S303) Request to check the availability of D2D communication; (S305) Request D2D connection inspection; (S307) Check the availability of D2D link setting and check the intention for D2D communication; (S315) Request generation of a D2D bearer; (S317) Request D2D bearer configuration and session management; (S319) Request RRC connection reconfiguration; (S321) Set a D2D bearer; (S323,S325) Response to RRC connection reconfiguration
