摘要:
A call setup method and apparatus for minimizing call setup delay by a UE in a mobile telecommunications system are provided. The method includes the steps of: if call setup for a packet call service is requested, determining by the UE if the requested service is a predetermined service sensitive to call setup delay; if the requested packet call service is the predetermined service sensitive to the call setup delay, establishing control information representing that the packet call service is sensitive to the call setup delay; and transmitting a request message requesting the call setup to a network, the request message including the control information. In the method, a network causes a UE using a packet call service sensitive to call setup delay to maintain a connected state, so that restart delay of the packet call service can be minimized.

A method and apparatus for performing Automatic Retransmission reQuest (ARQ) on packet data in a mobile communication system. The method includes receiving from a transmission entity performing ARQ, by a reception entity, a status report message including a Non-Acknowledged (NACK) signal for the packet data transmitted to the reception entity, and generating time information of the NACK signal; comparing, by the transmission entity, the generation time information with transmission complete time information for the packet data; and determining whether to retransmit the packet data depending on the comparison result, and performing retransmission of the packet data according to the determination step.
摘要:
A method and an apparatus for performing Hybrid Automatic Repeat reQuest (HARQ) of a packet in a mobile communication system. A User Equipment (UE) receives transmission resource allocation information indicating a transmission resource for uplink packet transmission and indicating a valid duration of the transmission resource, from a Node B over a downlink control channel, and transmits an HARQ packet using the transmission resource through an HARQ operation for the valid duration. The Node B transmits the transmission resource allocation information to the UE over the downlink control channel, and receives the HARQ packet through the HARQ operation using the transmission resource for the valid duration.
摘要:
A method and apparatus for controlling measuring the frequency of a new cell within a forbidden registration area when a User Equipment (UE) enters into the new cell in a mobile communication system are provided. If the UE recognizes the new registration area as forbidden, the UE does not measure the frequency of the current cell for a predetermined reference time, and searches for a suitable cell for a normal service by measuring other frequencies. If no suitable cell in the other frequencies is found, the UE removes a measuring limitation and searches for an acceptable cell for a limited service by measuring frequencies including frequency of the current cell.
摘要:
A method and terminal apparatus for transmitting a status report comprising a received status of packet data in a mobile communication system are provided, in which whether transmission of an implicit Negative Acknowledge (NACK) signal is required for requesting retransmission of at least one non-received data packet whose sequence number is unidentified is determined, if transmission of the implicit NACK signal is required, the implicit NACK signal including a sequence number of the last packet is generated among successfully received data packets, and a status report including the implicit NACK signal is transmitted to the transmitter, and if transmission of the implicit NACK signal is not required, a status report is transmitted to the transmitter including at least one of an ACK signal comprising a sequence number of a successfully received data packet and an explicit NACK signal comprising a sequence number of a non-received data packet whose sequence number is identified.
摘要:
A method for controlling a rate of a voice service in a mobile communication system supporting the voice service via a packet network. The method includes the steps of receiving a control message at a terminal from a radio network controller (RNC); if the control message indicates control of a downlink rate, determining a downlink rate according to the control message; setting a Change Mode Request (CMR) field of an uplink Voice over Internet Protocol (VoIP) packet according to the downlink rate, and transmitting the uplink VoIP packet from the terminal to the RNC; if the received control message indicates control of an uplink rate, determining an uplink rate according to the control message; and generating an uplink VoIP packet including uplink voice data generated according to the determined uplink rate and frame type (FT) information indicating the determined uplink rate, and transmitting the uplink VoIP packet from the terminal to the RNC.
摘要:
A method and apparatus for transmitting and receiving CQI in a wireless communication system are provided, in which when a UE transitions from a continuous reception state to a DRX state, CQI report resources are reallocated to the UE according to a CQI report resource reallocation rule agreed between the UE and an E-RAN, which obviates the need for signaling information about allocated new CQI report resources.
摘要:
A method is provided for transmitting an uplink scheduling request in a mobile communication system. A terminal compares a lowest priority for permitting transmission of the scheduling request notified from a radio resource controlling node with a highest priority among service priorities corresponding to generated data or control signals, if data or control signals to be transmitted in the uplink are generated from an upper layer. The terminal transmits the scheduling request to the radio resource controlling node to thereby request the radio resource controlling node to allocate radio resources for transmitting the data or control signals, when the highest priority is greater than or equal to the lowest priority.
摘要:
Disclosed is a method and apparatus for transmitting an uplink scheduling request in a mobile communication system. A radio resource controlling node sets a priority for scheduling request retransmission, and cyclically notifies the priority in downlink. A terminal does not retransmit a scheduling request when the highest priority included in the scheduling request to be retransmitted is lower than the lowest priority for scheduling request retransmission. Alternatively, the radio resource controlling node sets scheduling request retransmission cycles (timers) according to priorities, and transmits the cycles in the downlink. The terminal does not retransmit a scheduling request before a cycle (timer) corresponding to the highest priority included in the scheduling request expires after the scheduling request is initially transmitted or retransmitted.
