Abstract:
In a WCDMA mobile communication system, when the amount of packet traffic transmitted to or received from a UE decreases during a predetermined time in a CELL_DCH state in which a WCDMA packet data connection has been established, the UE transitions to a CELL_FACH state by a radio network controller (RNC). Thereafter, it is determined if there is no transmitted or received packet traffic during a certain time in the CELL_FACH state (which is an RRC state in which an RRC connection has been connected, and the dedicated physical channel has been released). When it is determined that there is no transmitted or received packet traffic during the certain time, the UE requests a network to release the RRC connection by utilizing a Signaling Connection Release Indication (SCRI) message. The invention enables a UE to check a packet transmission or reception flow, and to directly transmit the SCRI message to the network.

Claim (Index 1):
A modem chip comprising:\n memory to store a radio resource control (RRC) state including a cell dedicated channel (CELL_DCH) state, a cell forward access channel (CELL_FACH) state, a cell paging channel (CELL_PCH) state, and an idle state; and processing circuitry adapted to: obtain information indicating whether packet data is communicated between the modem chip and a network; determine, based at least in part on the information, that the packet data has not been communicated between the modern chip and the network for a specified period of time; transmit, based at least in part on the determining, a signaling connection release indication (SCRI) message to a radio network controller (RNC) corresponding to the network while a packet data protocol (PDP) connection is maintained between the modem chip and a serving general packet radio service support node (SGSN) corresponding to the network; receive an RRC connection release message from the RNC based at least in part on the transmitting of the SCRI message; and transition the RRC state from the CELL_DCH state or the CELL_FACH state to the idle state in response to the RRC connection release message received from the RNC.
