具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，并不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在LTE中，MBMS业务可以通过多播或者单播的方式传输，核心网统一控制核心网和接入网(如各种基站)之间接口上的传输方式和空口传输方式，核心网和接入网之间的接口上的传输方式和空口传输方式总是保持一致，即二者均是PTP方式或者二者均是PTM方式，核心网可以控制 MBMS在PTP或者PTM两种传输模式之间切换。此外，为了帮助终端识别当前小区有哪些MBMS业务在以PTM方式传输，接入网侧会通知终端哪些业务在以PTM方式传输，以单小区点对多点(SC-PTM)技术为例，接入网会在单小区-多播控制信道(single cell-Multicast Control Channel，SC-MCCH)上传输的无线资源控制(Radio Resource Control，RRC)消息SCPTMConfiguration中指示当前小区通过多播方式传输的业务列表，然后终端根据读取到的RRC消息SCPTMConfiguration进而判断希望接收的MBMS业务是否在通过多播模式传输；对于不在RRC消息SCPTMConfiguration中指示的MBMS业务，终端需要通过建立PDU会话的方式接收此MBMS业务。
在5G系统中MBMS在核心网和接入网之间的传输方式(PTP/PTM)，可能通过核心网或者接入网控制。而MBMS在空口的传输方式(PTP/PTM)是由接入网自己独立控制，即在网络侧的核心网和接入网之间通过PTM方式传输MBMS的前提下，接入网可以根据策略，选择在空口通过PTM发送MBMS，或者在满足一定条件下在空口停止使用共享无线资源发送，并为覆盖内的所有需要接收MBMS的终端分别配置专用无线资源以PTP的方式接收MBMS业务。基于上述机制，5G MBMS业务有三种传输方式，包括MBMS在核心网和接入网之间以PTM方式传输且空口通过PTM方式传输、MBMS在核心网和接入网之间以PTM方式传输且空口通过PTP方式传输、MBMS在核心网和接入网之间以PTP方式传输且空口通过PTP方式传输。
根据5G MBMS上接入网的新增功能，如接入网(NG-RAN)可以独立控制空口的传输模式。MBMS业务可以在核心网和接入网之间PTM方式传输，同时在空口通过PTP方式传输。这种传输方式下，终端不需要发起建立单播PDU会话的过程，只需要在NG-RAN的控制下接收相应数据无线承载(Data Radio Bearer，DRB)上的数据即可。但是如果采用现有MBMS业务通知机制，那么以这种方式传输的MBMS不会出现在接入网通知的MBMS列表中，终端在这种场景下依然会触发PDU会话的建立；如果小区覆盖内存在多个需要接收这个MBMS业务的终端，则每个终端均会发起不必要的PDU会话建立的过程，因而浪费了网络资源，增加了 核心网的负担。
因此，本申请实施例提供一种MBMS业务的传输模式指示方法、装置及存储介质，以解决采用现有方式进行MBMS业务的传输时会造成网络资源浪费的问题。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。

即接入网设备(如各种基站)可以向终端通知在核心网设备与接入网设备的接口间通过共享通道传输的所有MBMS业务，同时指示每个MBMS业务在空口的传输模式，实现了接入网设备对每个MBMS业务在空口的传输方式的指示，从而使得在MBMS业务在空口中以PTP模式进行传输时，终端不用再触发PDU会话建立过程，只需要在接入网设备的控制下接收相应DRB上的数据即可，解决了接入网设备在空口停止在共享无线资源上发送MBMS业务，并为覆盖内的所有需要接收MBMS的终端分别配置专用无线资源接收MBMS业务的场景下，终端还触发不必要的单播PDU会话建立流程以进行MBMS业务接收的问题，避免了网络资源的浪费，减轻了核心网的负担。

具体的，当接入网络设备对终端待接收的目标MBMS业务的传输模式进行指示，即当目标MBMS业务存在于传输模式指示信息所指示的在接口间通过共享通道传输的所有MBMS业务中，且指示目标MBMS业务在空口的传输模式为PTM模式时，终端可以在开始接收目标MBMS业务时直接通过PTM资源接收该目标MBMS业务。
具体的，目标MBMS业务可以存在于第一MBMS业务列表中，或者存在于第三MBMS业务列表中。
其二，当传输模式指示信息所指示的在接口间通过共享通道传输的所 有MBMS业务中存在终端待接收的目标MBMS业务，且目标MBMS业务在空口的传输模式为PTP模式时，则终端在开始接收目标MBMS业务时通过PTP资源接收目标MBMS业务。

具体的，终端通过PTP资源接收目标MBMS业务时，处于连接态的终端在开始接收目标MBMS业务时通过网络分配的PTP资源接收目标MBMS业务；处于空闲态或非激活态的终端在开始接收目标MBMS业务时，发起申请进入连接态，并在连接态下根据网络分配的PTP资源接收目标MBMS业务。

其四，当终端正在通过PTP资源接收目标MBMS业务，且根据传输模式指示信息确定目标MBMS业务在空口的传输模式由PTP模式转换为PTM模式时，则切换为通过PTM资源接收目标MBMS业务。
具体的，当终端已经开始通过PTP资源接收目标MBMS业务，即目标MBMS业务在空口中开始传输时的模式为PTP时，若终端接收到传输 模式指示信息且根据该传输模式指示信息确定该目标MBMS业务从空口PTP转换为PTM，则终端开始通过PTM资源接收该目标MBMS业务，从而实现了在空口的传输模式切换时，终端进行相对应的专用无线资源和多播共享无线资源之间的接收切换。
其五，当终端正在通过PTM资源接收目标MBMS业务，且根据传输模式指示信息确定目标MBMS业务在空口的传输模式由PTM模式转换为PTP模式时，则切换为通过PTP资源接收目标MBMS业务。
具体的，当终端已经开始通过PTM资源接收目标MBMS业务，即目标MBMS业务在空口中开始传输时的模式为PTM时，若终端接收到传输模式指示信息且根据该传输模式指示信息确定该目标MBMS业务从空口PTM转换为PTP，则终端开始通过PTP资源接收该目标MBMS业务，从而实现了在空口的传输模式切换时，终端进行相对应的专用无线资源和多播共享无线资源之间的接收切换。
具体的，终端在切换为通过PTP资源接收目标MBMS业务时，处于连接态的终端可以直接转为通过网络分配的PTP资源继续接收目标MBMS业务；处于空闲态或非激活态的终端则发起申请进入连接态，并在连接态下根据网络分配的PTP资源继续接收目标MBMS业务。
其六，当确定正在接收的目标MBMS业务从传输模式指示信息所指示的所有MBMS业务中删除时，发起PDU会话建立过程并在单播的PDU会话上继续接收目标MBMS业务。
具体的，若终端正在接收的目标MBMS业务存在于未更新的传输模式指示信息，且该目标MBMS业务从最新接收的传输模式指示信息所指示的所有MBMS业务中删除时，终端发起PDU会话建立过程并继续在单播的PDU会话上接收该目标MBMS业务，即对于核心网与接入网之间接口传输模式切换为PTP传输模式的MBMS业务，终端发起PDU会话建立过程，从而保证MBMS业务的连续性。
其七，当终端正在通过单播的PDU会话接收目标MBMS业务，且确定所述目标MBMS业务被添加至所述传输模式指示信息所指示的所有MBMS业务中时，释放所述PDU会话，并根据所述目标MBMS业务在空口的传输模式通过所述传输模式所对应的资源接收所述目标MBMS业务。
具体的，当终端正在通过单播的PDU会话接收目标MBMS业务时，若终端接收到传输模式指示信息且根据该传输模式指示信息确定该目标MBMS业务被添加至所述传输模式指示信息所指示的所有MBMS业务中时，则释放该PDU会话，并根据目标MBMS业务在空口的传输模式通过传输模式所对应的资源接收目标MBMS业务，从而避免了不必要的PDU会话过程所造成的网络资源浪费。
具体的，若目标MBMS业务在空口的传输模式为PTP模式，则终端通过PTP资源接收该目标MBMS业务，若目标MBMS业务在空口的传输模式为PTM模式，则终端通过PTM资源接收该目标MBMS业务。
这样，通过上述不同方式，实现了目标MBMS业务在不同情况下的接收过程，实现了终端不会触发不必要的PDU会话过程进行MBMS业务接收，避免了网络资源的浪费。
本实施例中的MBMS业务的传输模式指示方法，通过对核心网设备与接入网设备的接口间通过共享通道传输的所有MBMS业务进行指示，同时指示每个MBMS业务在空口的传输模式，使得在MBMS业务在空口中以PTP模式进行传输时，终端不用再触发PDU会话建立过程，只需要在接入网设备的控制下接收相应DRB上的数据即可，避免了网络资源的浪费，减轻了核心网的负担。
