摘要:
The present invention relates to a device for controlling a state of a terminal with respect to mobility management, and a method thereof. The state of the terminal includes a disconnected state and a connected state, the connected state includes an active state and an idle state, and the active state includes an active sub-state and a standby sub-state. The terminal in the active state updates location information for each cell, and the terminal in the idle state updates the location information for each radio access network registration area including a plurality of cells. The terminal in the active sub-state performs a handover when leaving a current cell. The terminal in the standby sub-state determines a quality of service (QoS) of packet data, and performs the handover or is set to be in the idle state according to the determined QoS.
