A user equipment (UE) supporting proximity services (ProSe) starts a D2D operation if at least one of conditions is satisfied. For example, when the UE detects radio link failure or handover failure, when a radio resource control (RRC) connection re-establishment procedure fails, when any cell is not detected, when neither an acceptable cell or suitable cell is found, when RRC connection release is received, or when the UE enters an idle mode, the UE may start the D2D operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for starting device-to-device operation in wireless communication system","description":"A method and apparatus for starting a device-to-device (D2D) operation in a wireless communication system is provided.
