Abstract: A channel synchronization method, system and device in the multicast broadcast single frequency network are disclosed, which relate to wireless communication filed and are used to solve the problem of unable to ensure the base station to synchronously send the multi-points control channel (MCCH) message in the multicast broadcast single frequency network (MBSFN) region in the prior art. The specific scheme is: the network device in the MBSFN obtains multimedia broadcast multicast service (MBMS) service information and confirms the time resource and the frequency resource that bears MBMS service information. The network device sends the MBMS service information, the time resource and the frequency resource information to the base station in the MBSFN. The base station utilizing the time resource and the frequency resource sends the MBMS service information to the terminal via MBMS point to MCCH. Consequently the purpose that the base station synchronously sends the MBMS service message in the MBSFN is achieved.
Abstract translation: 公开了一种组播广播单频网络中的信道同步方法，系统和装置，涉及无线通信领域，用于解决无法确保基站同步发送多点控制信道（MCCH）的问题， 消息在现有技术中的组播广播单频网（MBSFN）区域中。 具体方案是：MBSFN中的网络设备获取多媒体广播组播服务（MBMS）业务信息，确认承载MBMS业务信息的时间资源和频率资源。 网络设备在MBSFN中向基站发送MBMS服务信息，时间资源和频率资源信息。 利用时间资源的基站和频率资源通过MBMS点向MCCH向终端发送MBMS服务信息。 因此，实现基站在MBSFN中同步发送MBMS服务消息的目的。
