1. A terminal state controlling method, comprising:
- transiting a terminal into a dormant state when packet data are not received from the terminal in an active state for a predetermined time; and
transiting the terminal into an idle state when packet data to be transmitted to the terminal in the dormant state are not received for a predetermined time,wherein the active state and the dormant state are states in which the uplink and downlink traffic channels are allocated to the terminal,the active state being a state in which the terminal maintains a synchronization to the uplink and downlink traffic channels,the dormant state being a state in which the terminal breaks the synchronization to the uplink and downlink traffic channels, and whereinthe idle state is a state In which the uplink and downlink traffic channels are not allocated to the terminal.

Abstract
A terminal state controlling method and apparatus are provided. The terminal state includes a connected state and an idle state, and the connected state includes an active state and a dormant state. The active state includes a scheduling-ON state and a scheduling-OFF state. In the state controlling apparatus, a radio resource control (RRC) layer controls a transition between the active state and the dormant state, and a media access control (MAC) layer controls a transition between the scheduling-ON state and the scheduling-OFF state.

16. A terminal state controlling method, comprising:
-
transiting a terminal into a scheduling-OFF state when packet data are not received from the terminal in a scheduling-ON state for a predetermined time; and transiting the terminal into a dormant state when packet data are not received from the terminal in the scheduling-OFF state for a predetermined time, wherein the scheduling-ON state, the scheduling-OFF state, and the dormant state are states in which uplink and downlink traffic channels are allocated to the terminal, the scheduling-ON state being a state in which the uplink and downlink traffic channel resources are allocated to the terminal according to the terminal-supportable QoS, the scheduling-OFF state being a state in which the terminal discontinuously transmits/receives the packet data through the uplink and downlink traffic channels, and the dormant state being a state in which the terminal breaks a synchronization to the uplink and downlink traffic channels. - View Dependent Claims (17, 18, 19, 20)

21. A terminal state controlling apparatus comprising:
-
a resource manager for allocating uplink and downlink traffic channels to a terminal on the establishment of the terminal in an active state, and the terminal breaking a synchronization to the uplink traffic channel on the establishment of the terminal in a dormant state; and a scheduler for allocating a uplink traffic channel and a downlink traffic channel resource to the terminal according to the terminal-supportable QoS when the sub-state of the terminal in the active state is established as a scheduling-ON state, and for allowing the terminal to discontinuously receive and transmit packet data through the uplink and downlink traffic channels when the terminal in the active state has a sub-state established as a scheduling-OFF state. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
