为了便于理解本申请实施例，首先说明以下内容。
通信网络比如5G网络提供多播业务时，通过在RAN节点和CN节点间建立共享通道来传送一份数据，然后由RAN节点将接收到的这一份数据发送给多个终端。共享通道只发送下行数据，没有上行数据，因此只需要RAN节点和CN节点间协商共享通道信息，比如下行(Downlink，DL)通道信息(Tunnel Information)，包括传输地址和隧道标识等。
可选的，如图2所示，CN节点可以分别通过与各个RAN节点(图2中以3个RAN节点为例，但不以此为限)间的共享通道向各个RAN节点分别分发数据，这样的共享通道采用的是单播传输方式，共享通道信息中的传输地址为单播地址。
可选的，如图3所示，CN节点可以使用多播传输方式通过一个共享通道向多个RAN节点(图3中以3个RAN节点为例，但不以此为限)发送数据，即多个RAN节点加入一个多播组，CN节点通过该共享通道向该多播组发送一份数据，传输网络将这一份数据分发给多播组内的多个RAN节点，共享通 道信息中的传输地址为多播地址。
目前共享通道建立时，RAN节点需要通过AMF和MB-SMF间协商共享通道信息，比如DL Tunnel information。如果共享通道采用单播传输方式，RAN节点需要向MB-SMF提供共享通道信息，从而使得CN节点可以分别和各个RAN节点建立共享通道。而如果共享通道采用多播传输方式，则RAN节点需要从MB-SMF处获取共享通道信息，从而可以加入相应的多播组，并接收来自该多播组的相应共享通道数据。这种情况下，当共享通道采用多播传输方式时，由于RAN节点中可能存储有共享通道信息，因此无需从MB-SMF处获取共享通道信息，也即在建立共享通道时，无需AMF和MB-SMF间协商共享通道信息，无需AMF和MB-SMF间的信令交互过程。故，现有的共享通道建立过程中的不同核心网功能间的信令交互过程可以被优化。
为了优化不同核心网功能间的交互操作，本申请实施例提出了由RAN节点向第一核心网功能发送交互辅助信息，该交互辅助信息用于辅助第一核心网功能与第二核心网功能交互多播广播业务或会话管理相关的信息，或者辅助第一核心网功能拒绝与第二核心网功能交互多播广播业务或会话管理相关的信息。由此，借助RAN节点发送的交互辅助信息，可以使得第一核心网功能与或拒绝与第二核心网功能交互多播广播业务或会话管理相关的信息，从而减少第一核心网功能和第二核心网功能间的不必要的信令交互过程，优化不同核心网功能间的交互操作。
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信息控制方法、装置、网络功能及可读存储介质进行详细地说明。
需要说明的是，本申请中的网络功能，也可以称为网络单元或网元。
请参见图4，图4是本申请实施例提供的一种信息控制方法的流程图，该方法由RAN节点执行，如图4所示，该方法包括如下步骤：
步骤41：RAN节点向第一核心网功能发送交互辅助信息。
本实施例中，交互辅助信息用于辅助第一核心网功能与第二核心网功能 交互多播广播业务或会话管理相关的信息，或者，交互辅助信息用于辅助第一核心网功能拒绝与第二核心网功能交互多播广播业务或会话管理相关的信息。也就是说，交互辅助信息用于辅助第一核心网功能调用或拒绝调用第二核心网功能的服务化操作。
一些实施例中，交互辅助信息用于辅助第一核心网功能与第二核心网功能交互多播广播业务管理相关的信息。
一些实施例中，交互辅助信息用于辅助第一核心网功能与第二核心网功能交互多播广播会话管理相关的信息。
一些实施例中，交互辅助信息用于辅助第一核心网功能拒绝与第二核心网功能交互多播广播业务管理相关的信息。
一些实施例中，交互辅助信息用于辅助第一核心网功能拒绝与第二核心网功能交互多播广播会话管理相关的信息。
一些实施例中，第一核心网功能可选为AMF，相应的，第二核心网功能为MB-SMF。
本申请实施例的信息控制方法，RAN节点可以向第一核心网功能发送交互辅助信息，该交互辅助信息用于辅助第一核心网功能与第二核心网功能交互多播广播业务或会话管理相关的信息，或者辅助第一核心网功能拒绝与第二核心网功能交互多播广播业务或会话管理相关的信息。由此，借助RAN节点发送的交互辅助信息，可以使得第一核心网功能与或拒绝与第二核心网功能交互多播广播业务或会话管理相关的信息，从而减少第一核心网功能和第二核心网功能间的不必要的信令交互过程，优化不同核心网功能间的交互操作。
本申请实施例中，RAN节点可以在共享通道建立或共享通道释放的过程中，向第一核心网功能发送交互辅助信息。可选的，RAN节点可以通过以下任意一项，向第一核心网功能发送交互辅助信息：
共享通道建立请求、共享通道释放请求。
一些实施例中，RAN节点可以在向AMF发送的共享通道建立请求中携 带交互辅助信息，以辅助AMF判断是否需要与MB-SMF交互信息，从而在判断出可以不与MB-SMF交互时，减少AMF和MB-SMF间的共享通道建立请求/响应，从而减少AMF和MB-SMF间的不必要的信令交互过程，优化AMF与MB-SMF间的交互操作。
另一些实施例中，RAN节点可以在向AMF发送的共享通道释放请求中携带交互辅助信息，以辅助AMF判断是否需要与MB-SMF交互信息，从而在判断出可以不与MB-SMF交互时，减少AMF和MB-SMF间的共享通道释放请求/响应，从而减少AMF和MB-SMF间的不必要的信令交互过程，优化AMF与MB-SMF间的交互操作。
可选的，上述交互辅助信息可以满足以下至少一项：
包括需要发送给第二核心网功能的信息；比如，包括需要发送给第二核心网功能的N2会话管理(Session Management，SM)信息、位置信息等；

请参见图5，图5是本申请实施例提供的另一种信息控制方法的流程图，该方法由第一核心网功能比如AMF等执行，如图5所示，该方法包括如下步骤：
步骤51：第一核心网功能从RAN节点接收交互辅助信息。
本实施例中，交互辅助信息用于辅助第一核心网功能与第二核心网功能交互多播广播业务或会话管理相关的信息，或者，交互辅助信息用于辅助第一核心网功能拒绝与第二核心网功能交互多播广播业务或会话管理相关的信息。也就是说，交互辅助信息用于辅助第一核心网功能调用或拒绝调用第二核心网功能的服务化操作。

另一些实施例中，RAN节点可以在向AMF发送的共享通道释放请求中携带交互辅助信息，以辅助AMF判断是否需要与MB-SMF交互信息，从而在判断出可以不与MB-SMF交互时，减少AMF和MB-SMF间的共享通道释放请求/响应，从而减少AMF和MB-SMF间的不必要的信令交互过程，优化AMF与MB-SMF间的交互操作。
