下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的多播业务传输、传输指示方法、装置、终端及网络侧设备进行详细地说明。
如图2所示，本申请实施例提供一种多播业务传输指示方法，包括：
步骤201，网络侧设备发送状态指示信息给终端；
其中，所述状态指示信息用于辅助终端确定在接收多播业务时的状态。
需要说明的是，该状态指的是终端的RRC状态，即连接状态、空闲状态或非激活状态。
可选地，在步骤201之前，所述方法还可以包括网络侧设备确定当前的业务类型或一段时间后的业务类型，在确定该业务类型为多播业务的情况下，网络侧设备再执行步骤201。
需要说明的是，本申请是实施例中的状态指示信息主要用于终端进行接收状态信息的确定，其可以显式进行指示，也可以隐式进行指示，下面分别对这两种方式进行详细说明如下。
一、显式指示
需要说明的是，在此种情况下，该状态指示信息包括：接收状态信息。
进一步还需要说明的是，网络侧设备可以根据第一参数，确定终端与多播业务对应的接收状态信息，然后再发送给终端；
可选地，该第一参数包括：多播业务的服务质量(QoS)和/或网络负荷。
具体地，所述接收状态信息可以包括以下至少一项：
A11、终端在连接(Connected)状态接收多播业务；
需要说明的是，此种情况指的是，终端仅可以在Connected状态进行多播业务的接收，也就是说，所有感兴趣多播业务的终端，在接收到业务激活通知(activation notification)时，都需要进入连接态才能接收指定的多播业务。
例如，若网络侧设备通过网络负荷的方式进行A11确定时，若网络侧设备确定当前的负荷较小，则为了保证业务的接收准确率，可以直接给终端指示A11。
A12、终端能够保持在当前状态接收多播业务；
需要说明的是，此种情况指的是，终端可以不用进行状态转换直接在当前状态进行多播业务的接收，例如，当终端处于空闲(Idle)状态时，若需要接收多播业务，则终端在获取能够保持在当前状态接收多播业务的指示后，可以直接在Idle状态进行多播业务的接收；当终端处于非激活(inactive，也可以称为非活跃)状态时，若需要接收多播业务，则终端在获取能够保持在当前状态接收多播业务的指示后，可以直接在inactive状态进行多播业务的接收；当终端处于Connected状态时，若需要接收多播业务，则终端在获取终端能够保持在当前状态接收多播业务的指示后，可以直接在Connected状态进行多播业务的接收。
需要说明的是，此种情况尤其适用于非连接(Non-connected)状态的终端，也就是说，所有感兴趣多播业务的新版本终端，在接收到业务activation notification时，可以保持在自己当前状态进行指定业务的接收，不需要触发进入连接状态。
A13、终端能够在连接状态和非连接状态接收多播业务；
需要说明的是，此种情况指的是，终端既可以在连接状态进行多播业务的接收，也可以在非连接状态(即Idle状态或inactive状态)进行多播业务的接收，当终端接收到能够在连接状态和非连接状态接收多播业务的指示后，需要再进行判断，具体使用何种状态接收多播业务。
也就是说，网络侧设备可以允许部分终端进入连接状态进行多播业务接收，而另一些终端留在Idle状态或Inactive状态进行多播业务接收，如何决定可以参考多播业务的QoS需求、终端偏好、网络侧设备给定的比例等信息。
A14、能够进入连接状态接收多播业务的终端的比例参数；
需要说明的是，此种情况下网络侧设备给出一个0-1之间的数值，代表终端需要进入连接状态的比例，例如，0.4指代40％，0.6指代60％。当网络侧设备给出的是0.6时，即表示能够允许60％的终端进入连接状态接收多播 业务。
A15、允许不进入连接状态接收多播业务的终端的比例参数；
需要说明的是，此种情况下网络侧设备给出一个0-1之间的数值，代表终端不需要进入连接状态的比例，例如，0.4指代40％，0.6指代60％。当网络侧设备给出的是0.4时，即表示允许40％的终端不进入连接状态接收多播业务。
进一步需要说明的是，网络侧还可以通知终端该接收状态信息所对应的多播业务的范围，可选地，该接收状态信息适用于以下至少一项：
A21、发送所述状态指示信息的小区；
需要说明的是，此种情况指的是，该接收状态信息是小区粒度的，意味着对该小区下所有的多播业务都使用相同的一组接收状态信息，一般针对的是小区(cell)负荷较高无法容纳任何多播业务进入连接态的情况，或者是cell负荷较低推荐所有多播业务都进入连接态接收，或者对所有业务都采取按比例或者按需求决定是否进入连接态接收的情况；此种方式的控制粒度较粗。
A22、第一多播业务；
需要说明的是，该第一多播业务指的至少一个多播业务，即任一多播业务或任一组多播业务，也就是说，此种情况指的是该接收状态信息是多播业务粒度的，意味着该小区下，对每一个多播业务或者一组多播业务分别配置接收状态信息；此种方式的控制粒度更细。
A23、第一区域；
需要说明的是，该第一区域指的是任一区域，即接收状态信息是针对指定区域下的多播业务的，也就是说，终端在指定区域接收多播业务时，都是使用同一种状态，该指定区域可以为多个小区所覆盖的区域，也就是说，在此种情况下，通过小区列表来指示第一区域。
对于终端来说，当其获取到接收状态信息后，便可以在接收到多播业务激活通知时，依据该接收状态信息的指示，直接在对应的状态进行多播业务的接收。
需要说明的是，因A21和A22是明确的状态信息，而A23为终端提供了两种选择，在终端接收到的接收状态信息里包括的是A23的情况下，终端还 需要进行状态的进一步判断，具体地实现方式可以为：
根据所述网络侧设备确定所述状态指示信息的方式，所述终端确定接收多播业务所处的目标状态；
在所述目标状态下，所述终端进行多播业务的接收。
需要说明的是，所述根据所述网络侧设备确定所述状态指示信息的方式，所述终端确定接收多播业务所处的目标状态可以采用的实现方式，包括以下至少一项：
A31、在所述接收状态信息是由网络侧设备根据多播业务的第一特征确定的情况下，终端将多播业务的第一特征与特征门限值进行比较，根据所述比较结果，确定接收多播业务所处的目标状态；
需要说明的是，本申请中所提到的第一特征属于QoS条件，即此种情况指的是终端需要将感兴趣业务的QoS条件与网络侧配置或者标准规定的QoS条件门限进行比较，如果满足connected状态接收的条件，例如业务误块率要求较高，此时终端需要进入连接状态接收，如果不满足connected状态条件或者满足non-connected状态的条件，例如业务误块率要求较低，此时终端可以待在当前状态进行接收。
进一步需要说明的是，本申请实施例优选采用误块率进行比较，也就是说，在此种情况下，所述特征为误块率，特征门限值为误块率门限值，具体地，根据所述比较结果，确定接收多播业务所处的目标状态的实现方式包括以下一项：
A311、若目标业务的误块率大于或等于误块率门限值，则确定所述目标状态为非连接状态；
需要说明的是，当一个多播业务的误块率大于或等于给定的误块率门限值时，表明该多播业务对于业务误块率要求较低，则终端可以直接在非连接状态进行该多播业务的接收。
A312、若目标业务的误块率小于误块率门限值，则确定所述目标状态为连接状态；
需要说明的是，当一个多播业务的误块率小于给定的误块率门限值时，表明该多播业务对于业务误块率要求较高，则终端需要在连接状态进行该多 播业务的接收。
A32、在所述接收状态信息是由网络侧设备基于第二参数确定的情况下，终端生成一个随机数，根据所述随机数与第二参数的比较结果，确定接收多播业务所处的目标状态，所述第二参数包括：能够进入连接状态接收多播业务的终端的比例参数或允许不进入连接状态接收多播业务的终端的比例参数；
进一步需要说明的是，可选地，在所述第二参数为能够进入连接状态接收多播业务的终端的比例参数的情况下，所述根据所述随机数与第二参数的比较结果，确定接收多播业务所处的目标状态，包括以下一项：
A321、若所述随机数小于第二参数，则确定所述目标状态为连接状态；
也就是说，若终端生成的随机数小于能够进入连接状态接收多播业务的终端的比例参数，则终端需要在连接态下接收多播业务。
A322、若所述随机数大于或等于第二参数，则确定所述目标状态为非连接状态；
也就是说，若终端生成的随机数大于或等于能够进入连接状态接收多播业务的终端的比例参数，则终端可以在非连接态下接收多播业务。
可选地，在所述第二参数为允许不进入连接状态接收多播业务的终端的比例参数的情况下，所述根据所述随机数与第二参数的比较结果，确定接收多播业务所处的目标状态，包括以下一项：
A323、若所述随机数小于第二参数，则确定所述目标状态为非连接状态；
也就是说，若终端生成的随机数小于允许不进入连接状态接收多播业务的终端的比例参数，则终端可以在非连接态下接收多播业务。
A324、若所述随机数大于或等于第二参数，则确定所述目标状态为连接状态；
也就是说，若终端生成的随机数大于或等于允许不进入连接状态接收多播业务的终端的比例参数，则终端需要非连接态下接收多播业务。
进一步还需要说明的是，当确定目标状态的方式同时包括A31和A32时，可以规定采取如下其中一种方式：
A41、对于误块率高于误块率门限值的多播业务，这种情况对应于误块率要求低，终端按照比例判断进入Connected状态的概率；对其它多播业务， 终端默认留在non-connected状态；
A42、对于误块率低于误块率门限值的多播业务，这种情况下对应于误块率要求高，终端按照比例判断不进入connected状态的概率；对于其它多播业务，终端默认进入connected接收。
A33、根据终端需求，确定接收多播业务所处的状态；
需要说明的是，此种情况是终端依据自身的需求，来确定接收多播业务的所处的状态，例如，如果终端更期望省电，则可以直接确定在非连接状态进行多播业务的接收。
还需要说明的是，当确定目标状态的方式同时包括A32和A33时，由于A32的随机数的方式是为了控制进入连接态的终端比例，对于某个终端来说，如果它更期望省电，或者对业务性能要求不高，则可以不采用随机数的方式，直接选择留在当前状态，即不进入连接状态接收，这种情况不会给网络负荷加重负担，因此可以允许不采用随机数的方式；但是反过来，如果一个终端特别希望能有高质量的接收效果，不能允许它不经过随机数控制而直接进入连接状态接收，主要原因是如果所有终端都如此不受控，网络负荷将十分严重。
二、隐式指示
需要说明的是，在此种情况下，该状态指示信息包括：需要所述终端进入连接态进行接收的多播业务的特征门限值和/或需要所述终端保持在当前状态进行接收的多播业务的特征门限值。
优选地，所述特征门限值包括：误块率门限值。
需要说明的是，网络侧设备可以通过显式或者隐式的方式给出该状态指示信息，例如，对于需要进入连接态进行接收的多播业务的误块率门限值为10-4，所谓显式是指明确指出条件，误块率小于10-4，同时是否有优先级条件，时延条件等；隐式方式是指将这些条件作为默认参数写在标准中，网络指需要1bit表明是否需要使用这些条件判断即可，例如，对于需要使用需要进入连接态进行接收的多播业务的误块率门限值为10-4这一条件时，只需将该比特为设置为1，即表明状态指示信息中包括：需要进入连接态进行接收的多播业务的特征门限值这一特征。
需要说明的是，当终端接收到该状态指示信息后，需要确定接收多播业务所处的目标状态，然后在所述目标状态下，进行目标多播业务的接收。
可选地，在此种情况下，终端的具体实现方式为：
根据所述误块率门限值对应的目标多播业务的误块率与所述误块率门限值的关系，终端确定接收多播业务所处的目标状态；
在所述目标状态下，进行目标多播业务的接收。
可选地，所述根据所述误块率门限值对应的目标多播业务的误块率与所述误块率门限值的关系，终端确定接收多播业务所处的目标状态，包括以下至少一项：
B11、在目标多播业务的误块率小于误块率门限值的情况下，则确定所述目标状态为连接态；
需要说明的是，此种情况对应的是所述状态指示信息为需要进入连接态进行接收的多播业务的特征门限值；也就是说，当一个多播业务的误块率小于给定的误块率门限值时，也就是说，对于业务误块率要求较高，则终端需要在连接状态进行该多播业务的接收。
B12、在目标多播业务的误块率大于或等于误块率门限值的情况下，则确定所述目标状态为非连接态；
需要说明的是，此种情况对应的是所述状态指示信息为需要保持在当前状态进行接收的多播业务的特征门限值；也就是说，当一个多播业务的误块率大于或等于给定的误块率门限值时，也就是说，对于业务误块率要求较低，则终端可以直接在非连接状态进行该多播业务的接收。
进一步还需要说明的是，所述状态指示信息还可以包括以下至少一项：
B31、能够进入连接状态接收多播业务的终端的比例参数；
B33、允许不进入连接状态接收多播业务的终端的比例参数。
具体地，在此种情况下，终端需要先生成一个随机数；根据所述随机数与第二参数的比较结果，确定接收多播业务所处的目标状态；并在所述目标状态下，进行多播业务的接收；
其中，所述第二参数包括：能够进入连接状态接收多播业务的终端的比例参数或允许不进入连接状态接收多播业务的终端的比例参数。
可选地，在所述第二参数为能够进入连接状态接收多播业务的终端的比例参数的情况下，终端的具体实现方式包括以下一项：
B41、若所述随机数小于第二参数，则确定所述目标状态为连接状态；
也就是说，若终端生成的随机数小于能够进入连接状态接收多播业务的终端的比例参数，则终端需要在连接态下接收多播业务。
B42、若所述随机数大于或等于第二参数，则确定所述目标状态为非连接状态；
也就是说，若终端生成的随机数大于或等于能够进入连接状态接收多播业务的终端的比例参数，则终端可以在非连接态下接收多播业务。
可选地，在所述第二参数为允许不进入连接状态接收多播业务的终端的比例参数的情况下，终端的具体实现方式包括以下一项：
B51、若所述随机数小于第二参数，则确定所述目标状态为非连接状态；
也就是说，若终端生成的随机数小于允许不进入连接状态接收多播业务的终端的比例参数，则终端可以在非连接态下接收多播业务。
B52、若所述随机数大于或等于第二参数，则确定所述目标状态为连接状态；
也就是说，若终端生成的随机数大于或等于允许不进入连接状态接收多播业务的终端的比例参数，则终端需要非连接态下接收多播业务。
可选地，步骤201的一种可选地实现方式为：
发送目标信息给终端，所述目标信息中携带所述状态指示信息；
其中，所述目标信息包括以下至少一项：
C11、系统信息块(System Information Block，SIB)；
此种情况指的是，状态指示信息可以在SIB中，作用于所有的多播业务。
C12、用于多播业务激活通知的寻呼消息；
需要说明的是，该寻呼消息用于携带多播业务激活通知(multicast service activation notification)，也就是说，此时状态指示信息是伴随每个multicast service activation notification的，只针对特定的多播业务。
需要说明的是，C11可以认为是通用配置，仅在common signaling里出现，也就是说，SIB包含一组或者多组状态指示信息，如果是只有一组，则 意味着这个小区内的所有multicast service都使用该组状态指示信息，或者根据默认的规则使用该组状态指示信息；而C12可以认为是特殊配置，仅针对每个具体的业务或者一组具体业务出现，例如，伴随业务的activation notification一起携带，则状态指示信息只对这个业务或者这组业务起效。
进一步需要说明的是，当C11和C12两种情况同时存在时，当有针对业务的状态指示信息时，使用该状态指示信息，当没有针对业务的状态指示信息时，使用SIB中推荐的状态指示信息，如果两者都没有，采取默认方式，例如，该预先设置在接收状态，例如，设置在连接态进行多播业务的接收。
还需要说明的是，前面所提到的方式均代表的是网络侧设备的期望和推荐，可选地，终端还可以向网络侧设备上报辅助信息，以辅助网络侧设备进行状态指示信息的确定时考虑用户的倾向。
可选地，所述辅助信息包括以下至少一项：
D11、省电需求指示信息；
需要说明的是，该省电需求指示信息可以为是否省电的指示信息。
例如，在终端需要省电优先的情况下，所述省电需求指示信息用于指示终端需要省电。
D12、接收效果指示信息；
需要说明的是，该接收效果指示信息可以为是否采用低性能接收的指示信息。
例如，在终端需要采用低性能接收的情况下，接收效果指示信息用于指示终端采用低性能接收。
D13、接收状态指示信息；
需要说明的是，该接收状态指示信息可以为是否在非连接态下接收的指示信息。
例如，在终端倾向于在non-connected接收的情况下，接收状态指示信息用于指示终端在non-connected状态接收。
一般来说，由于终端要上报辅助信息，必须是Connected状态通过上行专用无线资源控制(UL dedicated RRC)信令进行，因此网络侧设备指示终端进入Connected状态而终端自己期望在non-connected状态接收，此时可以进 行辅助信息的上报。即终端根据网络侧设备的指示进入连接态以专用信令接收了多播业务配置和数据之后，向网络侧设备上报自己的倾向，例如省电优先，性能低优先级，倾向于non-connected接收等。网络侧设备接收到该终端上报的辅助信息，可以将该终端释放到Inactive状态甚至是Idle状态继续进行该多播业务的接收。
反方向，如果是网络侧设备控制终端在non-connected状态进行多播业务接收，可以采用如下实现方式之一：
实现方式一：如果该终端目前确实处于Idle状态，则不建议进行上报进而进入到Connected状态进行接收，否则的话如果希望请求的终端数目众多，网络负荷承担不了，状态转换和辅助信息上报的信令开销是白白浪费掉的。
实现方式二：如果终端目前处于Connected状态，例如有其它单播(unicast)业务正在发送，则可以考虑顺道上报一下辅助信息，向网络侧设备上报自己的倾向，例如电量充足，性能更看重，倾向于connected状态和点对点路径(Point To Point leg，PTP leg)接收等，看看网络侧是否能够有资源对该终端进行专门的配置。
实现方式三：如果终端目前处于Inactive状态，也可以回到连接态进行上报，类似上述实现方式二的过程；
还需要说明的是，网络侧设备还可以显式或者隐式指示上述三种实现方式是否允许，终端根据指示允许，才能进行相应的上报过程。
需要说明的是，本申请实施例给出了idle状态和inactive状态下终端能够接收多播业务的方式，网络侧设备可以灵活地根据需求控制终端在哪些状态进行接收，使得网络侧设备在兼顾终端多播业务接收效果的基础上，可以更灵活的提升系统整体效率。
需要说明的是，本申请实施例提供的多播业务传输指示方法，执行主体可以为多播业务传输指示装置，或者，该多播业务传输指示装置中的用于执行多播业务传输指示方法的控制模块。本申请实施例中以多播业务传输指示装置执行多播业务传输指示方法为例，说明本申请实施例提供的多播业务传输指示装置。
