摘要:
An efficient uplink timing synchronization procedure performed with a target cell upon handover of a User Equipment (UE) in active mode in a mobile communication system is provided, in which a cell transmitter signals to the UE that the uplink timing synchronization procedure is not required in the target cell, and the UE carries out uplink transmission to the target cell at an uplink timing used in a source cell without the uplink timing synchronization procedure.

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:
Disclosed is an apparatus and a method for radio connection setup in a mobile communication system. In the method, a UE reports mobility information to a network, and the network performs according to the mobility information of the UE. Therefore, it is possible to reduce complexity of the UE and reduce the waste in power consumption thereof, and reduce the signaling overhead of the network, thereby achieving efficient use of resources.

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:
Disclosed is a method and apparatus for transmitting/receiving a packet in a mobile communication system. When upper layer packets are multiplexed into a packet whose overall size is informed via a separate path, the size of the upper layer packet is not signaled if it can be calculated from the overall size of the packet, so that the size a packet transmitted/received over a radio channel can be reduced.
