附图说明
为了更清楚地说明本申请实施例的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
在本发明实施例中，MBS业务如果没有MBS业务数据需要接收，终端设备会被释放到INACTIVE/IDLE(非激活/空闲)态；当有MBS业务数据需要接收时，终端设备会转换到连接态并继续接收MBS业务数据。可见，在MBS业务中终端设备需要根据MBS业务数据的数据状态进行连接状态的切换。由此，如何合理有效地通知终端设备MBS业务数据的数据状态是一个需要解决的问题。
图1是本发明实施例提供的一种通信系统的场景示意图。如图1所示，该通信系统100可以包括至少一个网络设备101和至少一个终端设备102，网络设备101与终端设备102、终端设备102和终端设备102、网络设备101和网络设备101之间通过有线或无线通信技术连接。需要说明的是，图1所示的终端设备102和网络设备101的数量和形态并不构成对本发明实施例的限定。在不同的实施例中，网络设备101还可以连接到核心网设备，核心网设备未在图1中示出。
需要说明的是，本发明实施例提及的无线通信系统包括但不限于：窄带物联网系统(Narrow Band-internet of Things，NB-IoT)、全球移动通信系统100(Global  System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data Rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Timedivision-Synchronization Code Division Multiple Access，TDSCDMA)，长期演进系统(Long Termevolution，LTE)、第五代移动通信系统或者可能的第六代、第七移动通信系统、车载无线短距通信系统以及未来移动通信系统。
本发明实施例中，上述网络设备101是一种部署在无线接入网中，为终端设备102提供无线通信功能的装置。网络设备101可以包括但不限于基站(Base Station，BS)、站点(Station，STA，包括接入点(Access Point,AP)和非AP站点STA)、网络控制器、传输接收点(Transmission and Reception Point，TRP)、移动交换中心或者wifi中的无线接入点等，示例性地，通过无线信道与终端设备102进行直接通信的装置通常是基站。所述基站可以包括各种形式的宏基站、微基站、中继站、接入点或射频拉远单元(Remote Radio Unit，RRU)等。当然，与终端设备102进行无线通信的也可以是其他具有无线通信功能的网络设备101，本申请对此不做唯一限定。
终端设备102可以包括例如用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通信的设备，例如，具有无线连接功能的手持式设备、车载设备、可穿戴设备、计算设备或链接到无线调制解调器的其他处理设备。目前，一些终端的举例为：手机(Mobile Phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(Mobile Internet Device，MID)、可穿戴设备，虚拟现实(Virtual Reality，VR)设备、增强现实(Augmented Reality，AR)设备、工业控制(Industrial Control)中的无线终端、无人驾驶(Self Driving)中的无线终端、远程手术(Remote Medical Surgery)中的无线终端、智能电网(Smart Grid)中的无线终端、运输安全(Transportation Safety) 中的无线终端、智慧城市(Smart City)中的无线终端、智慧家庭(Smart Home)中的无线终端等。
需要说明的是，在不同系统中，设备的名称可能会有所不同，例如在LTE网络中，将基站称为演进的节点B(Evolved Node B，eNB或eNodeB)，在第三代(the3rd Generation，3G)网络中，称为节点B(Node B)等，在5G网络中，称为5G基站(NR Node B，gNB)。
在无线通信系统中，MBS业务数据从数据网络传输到核心网络(图1中未示出)，核心网络以共享MBS流量分发方法(shared MBS traffic dilivery method)或个人MBS流量分发方法(individual MBS traffic delivery method)传输到基站，最后由基站将MBS业务数据传输给单个或者一组终端设备。终端设备接收上述MBS业务数据，并且可以根据MBS业务数据的数据状态进行非激活/空闲态，以及连接态的切换。
图2-a是本发明实施例提供的一种MBS业务数据接收方法的流程图。该方法的执行主体为图1所示系统中的终端设备。如图2-a所示，该方法包括：
201，终端设备接收网络设备发送的第一信息。该第一信息包括至少一个MBS业务的数据状态信息。可选的，MBS业务的数据状态信息用于表示MBS业务是否有数据传输。可选的，MBS业务的数据状态信息可以表示MBS业务数据终止传输，或者，可以表示MBS业务数据进行传输等状态。
202，终端设备从各个MBS业务的数据状态中获取目标MBS业务的数据状态信息。其中，目标MBS业务为终端设备感兴趣的MBS业务。
203，当所述目标MBS业务的数据状态信息用于指示所述目标MBS业务的业务数据为传输态时，对所述目标MBS业务的业务数据进行接收；否则，不对所述目标MBS业务的业务数据进行接收。
其中，在MBS场景中，终端设备可以接收网络设备发送的各个MBS业务的数据状态信息。当该各个MBS业务中包含目标MBS业务，并且目标MBS业务 的业务数据为传输态时，终端设备对目标MBS业务的业务数据进行接收。可选的，目标MBS业务可以是一个或者多个MBS业务。
在一些实施例中，终端设备确定目标MBS业务的业务数据为传输态时，终端设备通过RRC连接从非激活/空闲态切换到连接态之后，接收目标MBS业务的业务数据。在一些实施例中，如果终端设备根据接收到的各个MBS业务的数据状态信息，确定目标MBS业务的业务数据终止传输时，终端设备可以从连接态释放到空闲态/非激活态。
在一些实施例中，不限制终端设备在接收MBS业务时的RRC连接状态，因此终端设备确定目标MBS业务的业务数据为传输态时，可以保持在当前的状态，直接从网络设备进行目标MBS业务数据的接收。当终端设备确定目标MBS业务的业务数据为终止传输时，停止目标MBS业务数据的接收即可，无需切换到非激活/空闲态。由此提高终端设备接收MBS业务数据的灵敏性。
进一步，对于上述第一信息，网络设备可以采用不同的方式发送给终端设备。在一些实施例中，第一信息可以承载于以下一种或多种信息中：MBS控制信息、系统信息、DCI以及短消息。其中，MBS控制信息可以承载于MBS控制信道或者广播信道中。短消息可以用DCI format 1_0的短消息域来传输。
具体的，对于第一信息中各MBS业务的数据状态信息其可以采用不同的实现方式。如图2-b所示，第一信息包括各个MBS业务的业务字段。每个MBS业务的业务字段中包括第一字段，第一字段用于指示对应MBS业务的数据状态信息。如图2-b所示，MBS业务的业务字段可以包括MBS业务标识和第一字段。当第一字段取值为1时，表示第一MBS业务的业务数据再次到来或者正在传输，即第一MBS业务的业务数据为传输态。当第一字段的取值为0时，表示第一MBS业务的业务数据停止传输。需要说明的是，MBS业务标识和第一字段在MBS业务字段中的位置可以根据实际需要设置，图2-b中第一字段位于MBS业务标识之后仅是一个示例。例如，将第一字段设置于MBS业务字段的最后位置处等。
可选的，第一信息中各MBS业务的数据状态信息的实现方式还可以是：第一信息包括状态位图，状态位图的比特位可以用于指示各个MBS业务的数据状态信息。如图2-c所示，状态位图包括n个比特位，MBS业务可以映射到一个比特位，映射的该比特位的取值可以表示相应MBS业务的数据状态信息。如图2-c所示，比特位0可以映射MBS业务1，比特位0的取值表示MBS业务1的数据状态信息。例如，比特位0的取值为1时，表示MBS业务1的业务数据再次到来或者正在传输，即MBS业务1的业务数据为传输态。当比特位0的取值为01时第一字段的取值为0，表示MBS业务1的业务数据停止传输。当然，比特位0也可以映射其它的MBS业务标识。
可选的，MBS业务与状态位图比特位的映射关系可以称为第一映射关系。网络设备可以将第一映射关系包含于第二信息发送给终端设备。其中，第二信息也可以承载于以下一种或多种信息的组合中：MBS控制信息、系统信息、DCI和短消息。需要说明的是，第一信息和第二信息可以承载于相同的信息中，也可以承载于不同的信息中。当第一信息和第二信息承载于不同的信息时，对第一信息和第二信息发送的先后顺序不作限定。在一些示例中，状态位图可以通过DCI或者短消息发送给终端设备，第一映射关系可以通过MBS控制信息或者系统信息发送给终端设备。又例如，状态位图可以通过MBS控制信息发送给终端设备，第一映射关系可以通过系统信息发送给终端设备。又例如，状态位图可以通过系统信息送给终端设备，第一映射关系可以通过MBS控制信息发送给终端。以上仅是对状态位图和第一映射关系承载方式的示例，对于其它可能的信息承载方式此处不再一一举例说明。终端设备根据第一映射关系，可以在状态位图中定位到目标MBS对应的目标比特位，并根据目标比特位的取值确定目标MBS业务的数据状态信息。例如，状态位图中的一个比特位对应一个MBS业务。终端设备基于第一映射关系定位到目标比特位，如果目标比特位取值为1，表示目标MBS业务的业务数据再次到来或者正在传输，即目标MBS业务的业务数据为传输态。 如果目标比特位取值为0，表示目标MBS业务的业务数据停止传输。
进一步，上述第一映射关系其可以采用显式方式表示，也可以采用隐式方式表示。可选的，第一映射关系采用显式方式表示包括：所述第二信息包括各个MBS业务与状态位图的各个比特位的对应关系。例如：网络设备提供三种MBS业务，MBS业务1、MBS业务2和MBS业务3。第二信息中包括该三个MBS业务分别对应的状态位图比特位。例如，MBS业务1对应比特位2；MBS业务2对应比特位0，MBS业务3对应比特位1。对于MBS业务与状态位图各比特位的映射关系，此处不再一一列举。
第一映射关系采用隐式方式表示，包括：所述第二信息包括MBS业务列表；各个MBS业务在所述MBS业务列表中的位置与所述状态位图的各个比特位具有对应关系。在一个示例中，各个MBS业务的排列序号与状态位图的各比特位具有对应关系。例如，MBS业务1、MBS业务2和MBS业务3的排列序号分别为1，2，3；该排列序号1，2，3分别对应状态位图的比特位0，1，2或者其它可能的对应方式。
进一步，第一信息中的数据状态信息除了采用第一字段、状态位图表示之外，还可以采用状态恢复索引表示。可选的，第一信息包括状态恢复索引，状态恢复索引与MBS业务具有对应关系，用于指示相应MBS业务的业务数据转换为传输态。例如，当某一MBS业务的数据状态发生变化时，网络设备将该MBS业务对应的状态恢复索引发送给终端设备。例如，状态恢复索引为4个比特，0010表示其所对应的MBS业务的数据状态发生了变更。如果在接收0010索引之前，该MBS业务数据为传输态，则接收到0010索引之后，该MBS业务数据状态变为停止传输。当然，如果在接收0010索引之前，该MBS业务数据为停止传输，则接收到0010索引之后，该MBS业务数据状态变更为传输态。在一些实施例中，网络设备在MBS业务数据转换为传输态时向终端设备发送该MBS业务对应的状态恢复索引。终端设备接收到状态恢复索引之后确定对应的MBS业务的业务 数据为传输态。
可选的，MBS业务与状态恢复索引的映射关系可以称为第二映射关系。网络设备可以将第二映射关系包含于第二信息发送给终端设备。其中，第二信息也可以承载于以下一种或多种信息的组合中：MBS控制信息、系统信息、DCI和短消息。需要说明的是，第一信息和第二信息可以承载于相同的信息中，也可以承载于不同的信息中。当第一信息和第二信息承载于不同的信息时，对第一信息和第二信息发送的先后顺序不作限定。在一些示例中，状态恢复索引可以通过DCI或者短消息发送给终端设备，第二映射关系可以通过MBS控制信息或者系统信息发送给终端设备。又例如，状态恢复索引可以通过MBS控制信息发送给终端设备，第二映射关系可以通过系统信息发送给终端设备。又例如，状态恢复索引可以通过系统信息送给终端设备，第二映射关系可以通过MBS控制信息发送给终端。以上仅是对状态恢复索引和第二映射关系承载方式的示例，对于其它可能的信息承载方式此处不再一一举例说明。终端设备根据第二映射关系可以对接收到的状态恢复索引对应的MBS业务进行定位，得知目标MBS业务的数据恢复传输。
进一步，上述第二映射关系其可以采用显式方式表示，也可以采用隐式方式表示。可选的，第二映射关系采用显式方式表示包括：所述第二信息包括各个MBS业务与状态恢复索引的对应关系。例如：网络设备提供三种MBS业务，MBS业务1、MBS业务2和MBS业务3。第二信息中包括该三个MBS业务分别对应的状态恢复索引。例如，MBS业务1对应状态恢复索引1；MBS业务2对应状态恢复索引2，MBS业务3对应状态恢复索引3。对于MBS业务与状态恢复索引的映射关系，此处不再一一列举。
第二映射关系采用隐式方式表示，包括：所述第二信息包括MBS业务列表；各个MBS业务在所述MBS业务列表中的位置与所述状态恢复索引具有对应关系。在一个示例中，各个MBS业务的排列序号与状态恢复索引具有对应关系。 例如，MBS业务1、MBS业务2和MBS业务3的排列序号分别为1，2，3；该排列序号1，2，3分别与状态恢复索引3，状态恢复索引2，状态恢复索引1一一对应。
结合第一信息承载方式以及第一信息实现方式的不同，以下将结合具体示例对数据状态信息的传输过程进行详细说明。
实施例一：网络设备基于多播控制信道(MultiCast Control Channel，MCCH)向网络设备发送MBS控制信息。用MBS控制信息承载各个MBS业务的数据状态信息。可选的，在MBS控制信息中各个MBS业务的数据状态信息的实现方式可以是为MBS业务配置第一字段，通过第一字段指示MBS业务的数据状态信息。可选的，在MBS控制信息中还可以通过状态位图或状态恢复索引指示MBS业务的数据状态信息。
其中，在MBS控制信息中为MBS业务配置第一字段，通过第一字段指示MBS业务的数据状态信息包括：在MBS控制信息中，配置有MBS业务的业务字段。所述业务字段包括第一字段，该第一字段用于表示MBS业务的数据状态信息。例如，第一MBS业务的第一字段取值为1时，表示第一MBS业务的业务数据再次到来或者正在传输，即第一MBS业务的业务数据为传输态。第一MBS业务的第一字段取值为0时，表示第一MBS业务的业务数据停止传输。
其中，在MBS控制信息中通过状态位图指示各个MBS的业务的数据状态信息包括：状态位图包括多个比特位，一个比特位映射一个MBS业务标识，比特位的取值表示对应MBS业务的数据状态信息。例如，比特位取值为1表示MBS业务的业务数据为传输态，比特位取值为0表示MBS业务的业务数据为停止传输。可选的，MBS业务标识与状态位图比特位的映射关系也可以通过MBS控制信息发送给终端设备。可选的，该映射关系也可以通过其它信息，如系统信息发送给终端设备。
在一个具体示例中，假设网络设备提供了三种MBS业务，MBS业务1、MBS 业务2和MBS业务3。网络设备可以将该三个MBS业务的业务标识和数据状态信息通过MBS控制信息发送给终端设备。可选的，该三个MBS业务的业务标识和数据状态信息可以通过MBS业务字段方式实现，也可以通过上述的状态位图或状态恢复索引的方式实现。终端设备接收到上述MBS控制信息之后，可以定位到其需要接收的MBS业务的业务标识和数据状态信息。例如，终端设备只需要接收MBS业务1，则终端设备在MBS控制信息中定位到MBS业务1的业务标识和数据状态信息。如果MBS业务1的数据状态信息指示MBS业务1的业务数据为传输状态，终端设备处于非激活/空闲态，终端设备发起RRC连接并在切换到连接态之后接收MBS业务1的业务数据。如果MBS业务1的数据状态信息指示MBS业务1的业务数据为停止传输时，终端设备从连接态切换到非激活/空闲态。
本发明实施例中，终端设备在暂时没有MBS业务数据需要接收时，可以释放到非激活/空闲态；当有MBS业务数据需要接收时，终端设备切换到连接态继续接收数据。而且本发明实施例可以通过状态位图方式通知终端设备所有MBS业务的数据状态信息，在MBS业务较多的情况下节省比特资源。
实施例二：网络设备基于广播控制信道(Broadcast Control Channel，BCCH)向终端设备发送系统信息。用系统信息承载各个MBS业务的数据状态信息。可选的，系统信息中各个MBS业务的数据状态信息的实现方式可以是为MBS业务配置第一字段，通过第一字段指示MBS业务的数据状态信息。可选的，在广播系统信息中还可以通过状态位图指示各个MBS业务的数据状态信息。可选的，在广播系统信息中还可以通过状态恢复索引指示各个MBS业务的数据状态信息。具体的，系统信息承载的各个MBS业务的数据状态信息的实现方式可以参见实施例一，此处不再赘述。
实施例三：网络设备基于物理下行控制信道(Physical Downlink Control Channel，PDCCH)向网络设备发送DCI或者短消息。用DCI或者短消息承载各 个MBS业务的数据状态信息。其中，考虑到DCI和短消息比特位有限，在DCI或者短消息中采用状态位图或者状态恢复索引的方式表示MBS业务的数据状态信息。
其中，在DCI或者短消息中采用状态位图表示MBS业务的数据状态信息包括：状态位图包括多个比特位，一个比特位映射一个MBS业务标识，比特位的取值表示对应MBS业务的数据状态信息。例如，比特位取值为1表示MBS业务的业务数据为传输态，比特位取值为0表示MBS业务的业务数据为停止传输。可选的，MBS业务标识与状态位图比特位的映射关系(第一映射关系)可以通过MBS控制信息或者系统信息发送给终端设备。终端设备接收到状态位图之后，可以根据第一映射关系在状态位图中定位目标MBS业务对应的目标比特位，并根据目标比特位的取值确定目标MBS业务的数据状态。
可选的，在DCI或者短消息中还可以采用状态恢复索引表示MBS业务的数据状态信息包括：一条状态恢复索引表示一个MBS业务的业务。当一个MBS业务的数据恢复传输时，网络设备可以将该MBS业务对应的状态恢复索引发送给终端设备。进一步，网络设备也可以将MBS业务与状态恢复索引的映射关系(第二映射关系)发送给终端设备。其中，由于DCI或者短消息比特位受限，该映射关系可以通过MBS控制信息或者系统信息发送给终端设备。终端设备接收到状态恢复索引之后，可以根据第二映射关系确定状态恢复索引指示的MBS业务的数据恢复了传输。
本实施例中，通过DCI或者短消息传输MBS业务的数据状态信息，也可以提高数据状态信息的传输时效，加快终端设备的反应速度。而且本实施例将MBS业务的数据状态信息映射到状态位图或者状态恢复索引上，可以节省比特资源。
图3是本发明实施例提供的另一种MBS业务数据接收方法。该方法的执行主体为图1所示系统中的网络设备。如图3所示，该方法包括：
301，网络设备向终端设备发送第一信息，所述第一信息包括至少一个MBS 业务的数据状态信息。其中，所述第一信息承载于以下一种或多种信息的组合中：MBS控制信息、广播系统信息、DCI及短消息。
其中，在不同的承载方式中，第一信息的实现方式可以是：第一信息包括各个MBS业务的业务字段，每个业务字段包括第一字段，所述第一字段用于指示对应MBS业务的数据状态信息。
可选的，所述第一信息包括：状态位图，所述状态位图的比特位用于指示各个MBS业务的数据状态信息。可选的，网络设备还向终端设备发送第二信息，第二信息包括：MBS业务与状态位图比特位的第一映射关系。。
可选的，所述第一信息包括：状态恢复索引，所述状态恢复索引与MBS具有对应关系，用于指示相应MBS业务的业务数据转换为传输态。可选的，网络设备还向终端设备发送第二信息，第二信息包括MBS业务与状态恢复索引的第二映射关系。
302，网络设备确定所述至少一个MBS业务中的部分或者全部MBS业务为传输态时，网络设备向终端设备发送所述部分或者全部MBS业务的业务数据。
上述第二信息也可以承载于以下一种或多种信息的组合中：MBS控制信息、广播系统信息、DCI及短消息。其中，第一信息和第二信息可以承载于相同的信息也可以承载于不同的信息中。
所述第一映射关系采用显式方式表示，包括：所述第二信息包括各个MBS业务与状态位图的各个比特位的对应关系；或者，所述第一映射关系采用隐式方式表示，包括：所述第二信息包括MBS业务列表；各个MBS业务在所述MBS业务列表中的位置与所述状态位图的各个比特位具有对应关系。
所述第二映射关系采用显式方式表示，包括：所述第二信息包括各个MBS业务与各个状态恢复索引的对应关系；或者，所述第二映射关系采用隐式方式表示，包括：所述第二信息包括MBS业务列表；各个MBS业务在所述MBS业务列表中的位置与所述状态恢复索引具有对应关系。
本发明实施例中，网络设备发送各MBS业务的数据状态信息的方式可以参见图2实施例的相关说明，此处不再赘述。
