A method and apparatus for transmitting and receiving control information in a mobile communication system. A User Equipment (UE) receives an UpLink Grant (ULG) signal from a BS, and transmits to the BS control information including state information indicating the absence of user data to be transmitted on a Physical Uplink Control CHannel (PUCCH).

Method and apparatus for transmitting/receiving control information in a mobile communication system

Provided are a method and an apparatus for extracting QoS parameters in a mobile device. In the method, all packets received from a terminal device are monitored, and SIP packets are filtered. When a real-time service application is executed on the terminal device, and an SIP request packet or an SIP response packet is filtered and input, QoS parameters are extracted from the SIP request packet or the SIP response packet. The extracted QoS parameters are incorporated into a wireless link data resource request and transmitted to a wireless network device. When a response to the wireless link data resource request is received, an uplink filter value for a new resource is extracted and added to a packet monitoring list.

Method and apparatus for extracting QoS parameters in mobile device

An apparatus and method for setting a default gateway address of a mobile terminal (MT). In the method, address configuration information is received from a network device. An address different from a Packet Data Protocol (PDP) included in the address configuration information is configured as a network address of the default gateway. Filtering is performed on a packet received by the mobile terminal.

Apparatus and method for setting a default gateway address in a mobile communication system

An apparatus and a method for addressing inefficiency of radio resources in processing response messages of a multi-message transmitted are provided. The apparatus includes a controller for transmitting consecutive message data to a message server and controlling the sending of a message to the message server indicating reception of response messages after receiving the response messages in reply to the transmitted message data.

Apparatus and method for transmitting message in a mobile communication system

Provided is a method and an apparatus for processing data at a high speed by a UE for data communication. In the method, received data is divided into a header and payload information, which are then stored in different memories. In the method, header processing and payload data processing can be performed in parallel, and two memory devices can perform parallel processing without sharing a bus.

Method and apparatus for data processing in mobile communication system

A method for retransmitting high-speed packet data in a transmission apparatus of a mobile communication system that simultaneously performs Automatic Retransmission reQuest (ARQ) that retransmits an ARQ packet reconfigured by allocating a sequence number to data delivered from an upper layer, and Hybrid Automatic Retransmission reQuest (HARQ) that multiplexes a plurality of ARQ packets into one HARQ packet and performs repeated retransmission on the HARQ packet within a maximum retransmission limit value. A transmitting HARQ entity checks a missing ARQ packet and sends a Negative Acknowledgement (NACK) for the missing ARQ packet to a transmitting ARQ entity. The transmitting ARQ entity receives an Acknowledged (ACK) for ARQ packets from a receiving ARQ entity, detects at least one missing ARQ packet according to the NACK and the ACK, configures a retransmission packet with the detected ARQ packet, and retransmits the retransmission packet.

Retransmission apparatus and method for high-speed data processing

A method and apparatus for setting up a Point-to-Point Protocol (PPP) link between a Terminal Equipment (TE) and a Mobile Terminal (MT), and between the MT and a Base Station Interworking Function (IWF). A method for setting up a PPP link for transmitting a packet between a TE and an IWF, which connects the TE and a packet network to each other, includes determining first option information to be used for a PPP link on a Um interface between an MT and the IWF, determining second option information to be used for a PPP link on an Rm interface between the MT and the TE, to make the second option information identical to the first option information; and transmitting, by the MT, frames transmitted/received through the PPP links between the TE and the IWF in a pseudo network mode, when the first and second option information have been determined.

A data flow control apparatus of a mobile terminal that performs reverse communication from a high speed communication device to a wireless network. An Rm interface unit receives data from the high speed communication device and buffers the received data in a byte stream format. An Operating System (OS) device driver includes a first packet buffer queue for reading and storing data buffered in the Rm interface unit upon receipt of an interrupt from the Rm interface unit. The OS device driver manages a first linked list for managing data stored in the first packet buffer queue. A Um interface unit includes a second packet buffer queue having the same buffer structure as that of the first packet buffer queue. The Um interface unit manages a second linked list for managing data stored in the second packet buffer queue, converts the data stored in the second packet buffer queue into a frame format, and transmits the frame-format data to a wireless network. A packet processor de-links an address of the data stored in the first packet buffer queue from the first linked list, and links an address of the de-linked data to the second linked list, to deliver the data from the first packet buffer queue to the second packet buffer queue. A controller controls data flow of the first packet buffer queue.
