    • A mobile communication system supporting an MBMS service includes a Node B having a plurality of transport channels and at least one UE communicating with the Node B. The Node B selects a transport channel for MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel; transmits a system information block indicating the selected transport channel to a cell area where UEs are located, using a primary common control physical channel; and transmits the MBMS control information to the cell area using the selected transport channel. The UE receives a system information block indicating a transport channel selected to transmit MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel, over a primary common control physical channel; receives the MBMS control information over the selected transport channel among the plurality of the transport channels, using the system information block; and receives the MBMS service using the MBMS control information.

    • 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.
    • 方法和装置执行从基于OFDM的E-UMTS系统到基于CDMA的UMTS系统的切换。 经由E-UMTS系统与PDN通信的UE测量UMTS系统的信号强度,并向E-UMTS系统发送指示测量信号强度的测量报告消息。 E-UMTS系统的无线接入网络(E-RAN)基于测量的信号强度来确定是否执行从E-UMTS系统到UMTS系统的切换。 如果要执行切换,E-UMTS系统的核心网络(E-CN)响应于来自E-RAN的切换请求,为UE生成PDP上下文和MM上下文。 E-CN使用PDP / MM上下文为UE建立到UMTS系统的GGSN的数据隧道。 在建立数据隧道之后,E-CN向UE发送切换命令消息,该切换命令消息包括要被UE用于接入UMTS系统的无线承载(RB)信息。 UE使用RB信息访问UMTS系统。 在接入UMTS系统之后,UE经由PDN与UE之间的E-CN,数据隧道,SGSN和RAN的RAN组成的数据传输路径转发UE的用户数据。

    • Disclosed is a method for resuming header decompression by receiving multimedia broadcast/multicast service (MBMS) packet data having compressed headers in a mobile communication system providing the MBMS. The method includes the steps of detecting a moving of user equipment (UE) receiving the MBMS into a new cell from an old cell, copying and storing old header decompression context information used in the old cell, initializing a dynamic part to decompress headers of packet data for the MBMS and waiting for an IR-DYN packet until the IR-DYN packet has been received in the UE, in order to update the old header decompression information, creating a new header decompression context through updating the old header decompression information by using the IR-DYN packet when the IR-DYN packet has been received in the UE, and decompressing the headers of the packet data for the MBMS transmitted from the new cell by using the new header decompression context.
    • 公开了一种通过在提供MBMS的移动通信系统中接收具有压缩报头的多媒体广播/组播服务(MBMS)分组数据来恢复报头解压缩的方法。 该方法包括以下步骤:从旧单元检测接收MBMS的用户设备(UE)移动到新小区中的步骤,复制和存储在旧小区中使用的旧报头解压缩上下文信息,初始化动态部分以解压缩报文的报头 用于MBMS并等待IR-DYN分组的数据,直到在UE中已经接收到IR-DYN分组为了更新旧的报头解压缩信息,通过使用更新旧的报头解压缩信息来创建新的报头解压缩上下文 当在UE中接收到IR-DYN分组时,IR-DYN分组,并且通过使用新的报头解压缩上下文解压缩从新小区发送的MBMS的分组数据的报头。
