Description

多播业务、专用业务发送、接收方法和装置 技术领域
本发明涉及通信技术领域，尤其涉及一种多播业务、专用业务发送、接收方法和装置。
背景技术
目前，为了实现对一组用户设备(User Equipment，UE)的调度，3GPP标准提出了单小区点到多点(Single cell point to multipoint，SC-PTM)技术，在该技术中，小区基站通过G-RNTI来同时向多个UE调度业务数据，每个G-RNTI可以关联一个多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)。SC-PTM的信道包含单小区MBMS点到多点控制信道(Single cell MBMS point-to-multipoint Control Channel，SC-MCCH)和单小区MBMS业务信道(Single cell MBMS traffic Control Channel，SC-MTCH)。其中SC-MCCH信道用于传输控制消息，SC-MTCH信道用于传输业务信息。如图1所示，SC-MCCH信道以周期方式发送控制消息。考虑到UE省电原因，SC-MTCH也可以按照周期方式调度业务数据，如果对应的调度时间有多播业务的业务数据需要传输，则在对应的调度时间进行业务调度。
在UE设计中为了考虑成本因素，一般同一个子帧能够处理的数据块的个数是受限的。对于低等级的UE而言，不能同时处理一个MCCH数据块加一个MTCH数据块，或者一个MTCH数据块加一个DTCH数据块。但由于MCCH数据块和MTCH数据块是周期出现的，有可能部分MTCH数据块和MCCH数据块会出现在同一子帧，这样，UE就需要无法同时接收MTCH和MCCH，影响了多播业务的业务数据的发送效率和接收效率。

图2为本发明提供的多播业务发送方法一个实施例的流程图，如图2所 示，具体包括以下步骤：
201、基站获取单小区多媒体广播多播业务的点到多点控制信道(Single cell MBMS point-to-multipoint Control Channel，SC-MCCH)的配置信息，配置信息中包括：SC-MCCH信道对应的无线网络临时标识(MCCH-Radio Network Temporary Identity，MCCH-RNTI)，以及SC-MCCH控制消息的预定发送时间信息。
本发明提供的多播业务发送方法的执行主体为多播业务发送装置，多播业务发送装置具体可以为发送多播业务的业务数据的基站或者其他服务器。多播业务的业务数据的接收方可以为订阅多播业务的用户设备。其中，点到多点控制信道SC-MCCH用于传输配置信息或SC-MCCH控制消息等。配置信息可以由基站预先配置并通过SC-MCCH信道发送给订阅多播业务的UE。
本实施例中，基站可以为控制信道SC-MCCH分配无线网络临时标识MCCH-RNTI，使得UE可以根据MCCH-RNTI从SC-MCCH信道获取SC-MCCH控制消息。
202、基站获取多播业务的业务数据的预定发送时间信息。
本实施例中，基站针对每种多播业务分配一个单小区MBMS业务信道(Single cell MBMS traffic Control Channel，SC-MTCH)，及其相应的G-RNTI，并为此业务配置发送时间信息。
203、基站判断SC-MCCH控制消息的预定发送时间信息和多播业务的业务数据的预定发送时间信息是否重叠。
本实施例中，基站可以将多播业务的业务数据的预定发送时间信息与SC-MCCH控制消息的预定发送时间信息进行比较，判断是否有重叠。其中，由于多播业务的业务数据一般需要采用SC-MTCH信道的多个周期才能完成传输，也就是说，多播业务的业务数据的预定发送时间信息可能为多个时间段，对应SC-MTCH信道的多个周期，此时基站需要将多播业务的业务数据的多个时间段分别与SC-MCCH控制消息的预定发送时间信息进行比较，判断是否重叠。
本实施例中，SC-MCCH控制消息的预定发送时间信息可以包括：SC-MCCH控制消息的重复周期和偏移参数；多播业务的业务数据的预定发 送时间信息包括：多播业务的业务数据的重复周期和偏移参数。对应的，步骤203具体可以为：根据SC-MCCH控制消息的重复周期和偏移参数，确定SC-MCCH控制消息在SC-MCCH信道中的子帧位置；根据多播业务的业务数据的重复周期和偏移参数，确定多播业务的业务数据在SC-MTCH信道中的子帧位置；判断SC-MCCH控制消息在SC-MCCH信道中的子帧位置和多播业务的业务数据在SC-MTCH信道中的子帧位置是否重叠。其中，SC-MCCH控制消息的重复周期具体可以标示传输SC-MCCH控制消息所采用的周期的序列号或者序数，偏移参数可以标示传输SC-MCCH控制消息所采用的是相应周期内的具体时间段。
204、若SC-MCCH控制消息的预定发送时间信息和多播业务的业务数据的预定发送时间信息重叠，则基站根据预设的偏置参数对多播业务的业务数据的预定发送时间信息进行调整，以使SC-MCCH控制消息的预定发送时间信息和多播业务的业务数据的预定发送时间信息不重叠；或者，对SC-MCCH控制消息和多播业务的业务数据进行复用处理，并根据多播业务对应的G-RNTI将复用后的数据块发送给UE。
本实施例中，在第一种实施场景下，预设的偏置参数为正/负N个子帧，N为正整数。对应的，根据预设的偏置参数对多播业务的业务数据的预定发送时间信息进行调整的过程具体可以为，将多播业务的业务数据的预定发送时间信息推后N个子帧或者提前N个子帧。如图3所示，为将多播业务的业务数据的预定发送时间信息推后2个子帧的示意图。
在第二种实施场景下，预设的偏置参数为预设时间窗口。对应的，根据预设的偏置参数对多播业务的业务数据的预定发送时间信息进行调整的过程具体可以为，在预定发送时间信息对应的预设时间窗口内对多播业务的业务数据的预定发送时间信息进行推后或提前。如图4所示，为在预定发送时间信息对应的预设时间窗口内对多播业务的业务数据的预定发送时间信息进行推后的示意图。
本实施例中，预设的偏置参数可以为基站和各个UE预先设定好的偏置参数，或者UE接收的基站预先设置的偏置参数。
进一步的，在上述实施例的基础上，多播业务的配置信息中还可以包括：基站为多媒体广播多播业务信道SC-MTCH分配的的无线网络临时标识 G-RNTI或者多播业务的临时多播组标示TMGI。
对应的，对SC-MCCH控制消息和多播业务的业务数据进行复用处理的过程具体可以为：将多播业务的TMGI标示或者基站为SC-MTCH信道分配的无线网络临时标识G-RNTI，以及多播业务的业务数据和SC-MCCH控制消息复用在同一数据块中，得到复用后的数据块，复用后的数据块中包括：SC-MCCH控制消息，TMGI标示或者G-RNTI，以及TMGI标示或者G-RNTI对应的多播业务的业务数据。
其中，多播业务的临时多播组标示(Temporary multicast Group Identifier，TMGI)为唯一标示多播业务的标识，与多播业务一一对应。
