Abstract: PURPOSE: A node synchronization and data transmission control method on MBSFN(Multimedia Broadcast multicast Single Frequency Network) is provided to synchronize a node through a control message between an MCE(Multi-Cell/Multicast Coordinate Entity) and an eNB(Evolved Node Bs). CONSTITUTION: A node is synchronized as an SFN(Subframe Number) value in an MBSFN area(S201-S203). The eNB and a UE transmit initial base time to the eNB and the UE for data traffic process. An MCE confirms scheduling starting time of the eNB to a BM-SC for session starting.

Abstract: PURPOSE: An MBMS(Multimedia Broadcast Multicast Service) broadcasting service receiving system and a method thereof are provided to receive an MBMS by a unicast bearer using synchronization information which is the same as a multicast bearer according to wireless quality or performance of a terminal. CONSTITUTION: When a selected broadcast service is not transmitted to a first bearer, a transmission channel setting unit(130) sets a second bearer by a transmission channel. When the selected broadcast service is transmitted to both the first bearer and the second bearer, the transmission channel setting unit sets the first bearer about a portion of the selected broadcast service as a transmission channel. The transmission channel setting unit sets the second bearer about the other portions of the selected broadcast service as a transmission channel. A broadcast service receiving unit(140) receives an MBMS broadcast service which is selected according to the setup transmission channel.

Abstract translation: 目的：提供MBMS（Multimedia Broadcast Multicast Service，多媒体广播多播业务）广播业务接收系统及其方法，根据无线质量或终端性能，使用与多播承载相同的同步信息，通过单播承载接收MBMS。 构成：当所选择的广播业务不发送到第一承载时，传输信道设置单元（130）通过传输信道设置第二承载。 当所选择的广播服务被发送到第一承载和第二承载时，传输信道设置单元将关于所选广播服务的一部分的第一承载设置为传输信道。 传输信道设置单元将关于所选广播服务的其他部分的第二承载设置为传输信道。 广播服务接收单元（140）接收根据建立传输信道选择的MBMS广播服务。
