Device for Controlling Terminal State, Method Thereof, and Device for Transmitting Paging Message
First Claim
1. A method for controlling a state of a terminal, the method comprising:
- setting the terminal to be in an active state; and
setting the terminal to be in an idle state when a quality of service (QoS) required by the terminal in the active state is lower than a predetermined level,wherein the terminal updates location information for each cell in the active state, and the terminal in the idle state updates the location information for each radio access network registration area (RRA) including a plurality of cells.

Abstract
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.

13. A method for controlling a state of a terminal, the method comprising:
-
setting the terminal to be in an active sub-state; setting the terminal to be in a standby sub-state when a quality of service (QoS) required by the terminal in the active sub-state is lower than a predetermined level; setting the terminal to be in an idle state when the QoS required by the terminal in the standby sub-state is lower than the predetermined level, wherein, in the active sub-state, the terminal performs a handover when the terminal leaves a current cell, in the standby sub-state, the terminal determines a QoS of the packet data and performs a handover when the determined QoS is greater than the predetermined level, and is set to be in the idle state when the determined QoS is lower than the predetermined level, and in the idle state, the terminal updates location information for each radio access network registration area having a plurality of cells. - View Dependent Claims (14, 15, 16)

17. A device for controlling a state of a terminal, the device comprising:
-
a state controller for controlling the terminal to update location information for each cell when setting the terminal to be in an active state, and controlling the terminal to update the location information for each radio access network registration area having a plurality of cells when setting the terminal to be in an idle state; and a sub-state controller for setting the terminal in the active state to be in an active sub-state or in a standby sub-state, wherein, in the active sub-state, the terminal performs a handover when the terminal leaves a current cell, and in the standby sub-state, the terminal determines a quality of service (QoS) of packet data and performs the handover when the determined QoS is greater than a predetermined level, and is set to be in the idle state when the determined QoS is lower than the predetermined level. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A device for transmitting a paging message to a first terminal in a first radio access network registration area, the device comprising:
-
a terminal location management unit for managing location information of a terminal in a plurality of radio access network registration areas having the first radio access network registration area; and a controller for transmitting the paging message to the terminal location management unit when receiving the paging message from an external network, wherein the terminal location management unit manages a location of the terminal in an active state for each cell and manages the location of the terminal in an idle state for each radio access network registration area having a plurality of cells, and when receiving the paging message for the first terminal in the idle state, the terminal location management unit transmits the paging message along with information on the first radio access network registration area to a plurality of base stations corresponding to the plurality of radio access network registration areas managed by the terminal location management unit so that the plurality of base stations corresponding to the first radio access network registration area transmit the paging message to a radio link. - View Dependent Claims (29)
