Abstract: An apparatus for controlling the states of a terminal, a method thereof, and an apparatus for transferring a paging message are provided to increase efficiency in using radio resources and to minimize the power consumption of a terminal by controlling state transition of the terminal according to QoS levels and applying different mobility management methods according to states of the terminal. A state control apparatus comprises a state control part(410), which exists in a network layer(III), and a sub-state control part(430), which exists in a data link layer(II). The state control part(410) sets a terminal to become a connected state or a disconnected state. Also the state control part(410) transits disconnected state of the terminal to an active state or an idle state. The sub-state control part(430) transits the active state of the terminal to an active sub-state or an idle sub-state. The state control part(410) allocates shared radio resources when the terminal is in the active state. The sub-state control part(430) measures the level of QoS through a measurement channel when the terminal is in the active sub-state, and allocates a part of shared radio resources dedicatedly to the terminal. The sub-state control part(430) inactivates the measurement channel when the terminal is in the idle sub-state. The sub-state control part(430), when the terminal is in the idle sub-state, operates a control channel and a data channel in a DTX(Discontinuous Transmission) or DRX(Discontinuous) method.

Abstract: A state control device of a cellular system and a controlling method are provided to control state transition of a terminal according to QoS(Quality of Service) and the type of a packet service, thus efficient use of radio resources is possible while power consumption is reduced. When the state of a terminal is set as an active state, a resource manager(410) allocates reverse and forward traffic channels to the terminal, and if the state is set as an idle state, the manager(410) enables the terminal to stop synchronous maintenance for the reverse traffic channel. When a sub state of the active-state terminal is set as a scheduling state, a scheduler(440) allocates resources of the reverse and forward traffic channels to the terminal according to QoS supported to the terminal, and when the sub state is set as a scheduling excluding state, the scheduler(440) enables the terminal to non-continuously transceive packet data through the reverse and forward traffic channels.

Abstract: Disclosed are a turbo code encoder and a code rate decreasing method thereof. The turbo code encoder includes: a first convolutional encoder for receiving a bit to be encoded, and generating a systematic bit and a first parity bit; an interleaver for receiving the bit to be encoded, in parallel with the first convolutional encoder, and interleaving the received bit; and a second convolutional encoder for receiving the interleaved bit from the interleaver and generating a second parity bit. The code rate decreasing method of the turbo code encoder having a code rate of 1/3 includes repeatedly outputting predefined bits among the bits output from the first and second convolutional encoders.
