摘要： A method and apparatus for initiating communications on a shared channel in a mobile communication system are provided. A user equipment transmits an uplink signal for requesting communications on the shared channel to a Node B, and waits for a delay duration without monitoring a downlink after transmitting the uplink signal. When the delay duration has elapsed, the user equipment monitors the downlink during a valid period and determines whether a downlink signal responding to the uplink signal is received in a transmission time interval within the valid period. When the downlink signal is received in the valid period, the user equipment transmits and receives data on the shared channel.

摘要： A method and apparatus performs handover from an OFDM-based E-UMTS system to a CDMA-based UMTS system. A UE in communication with a PDN via the E-UMTS system, measures signal strength of the UMTS system, and sends a measurement report message indicating the measured signal strength to the E-UMTS system. A radio access network (E-RAN) of the E-UMTS system, determines whether to perform handover from the E-UMTS system to the UMTS system based on the measured signal strength. If the handover is to be performed, a core network (E-CN) of the E-UMTS system generates a PDP context and an MM context for the UE in response to a handover request from the E-RAN. The E-CN sets up a data tunnel for the UE to a GGSN of the UMTS system using the PDP/MM context. After setting up the data tunnel, the E-CN sends to the UE a handover command message including information on a radio bearer (RB) to be used by the UE to access the UMTS system. The UE accesses the UMTS system using the RB information. After accessing the UMTS system, the UE forwards user data for the UE via a data transmission path composed of the E-CN, the data tunnel, a SGSN, and a RAN of the UMTS system, between the PDN and the UE.

摘要： A method for efficiently utilizing radio resources by reducing a size of a PDU of an RLC layer in a mobile communication system supporting a VoIP service. In the method, an RLC PDU is framed without inserting information regarding a start point and an end point of a voice packet, or existence or absence of padding, such that a size of overhead according to transmission of the voice packet can be reduced. Consequently, restricted radio resources can be efficiently used.

摘要： Disclosed are an apparatus and method for providing packet data service from a radio network controller (RNC) to user equipment (UE) in a mobile communication system. A radio bearer (RB) of a predetermined channel type is configured to compress and de-compress headers of packets passed between the RNC and the UE. The packet data service is provided from the RNC to the UE via the RB. When the channel type is changed, configuration information associated with an RB of the changed channel type is determined. Header compression (HC) context used in the RB of a previous channel type is acquired according to the configuration information and the RB of the changed channel type including the acquired HC context is configured. The packet data service is continuously provided via the RB of the changed channel type. Therefore, the invention reduces waste of radio resources that is due to a channel type change and delay that is due to system reset.

摘要： A method for selecting a cell by a user equipment (UE) to receive a Multimedia Broadcast/Multicast Service (MBMS) service in a mobile communication system which supports the MBMS service with different frequency allocations (FAs) in the same area. In the method, a radio network controller (RNC) transmits information on an MBMS cell to the UE, and the MBMS cell information includes an MBMS offset for guaranteeing priority for cell reselection to the MBMS cell. The UE performs cell reselection using the MBMS cell information and receives the MBMS service from the reselected cell.
