    Patent number: 10285076
    Abstract: The present disclosure relates to a method and device for controlling a Downlink Data Notification (DDN) message, which can reduce the DDN messages that occur while a user equipment transits from an active (ECM-active) state to an inactive (ECM-idle) state. During a bearer activation procedure according to a request from a user equipment, the DDN message control apparatus of the present disclosure sets a DDN flag value to a predetermined value when uplink data is received. When a DDN message is received from outside, the apparatus identifies the DDN flag value and stores the DDN message in case that the DDN flag value is identical with the predetermined value.
