所述终端检测到所述广播业务对应的广播信道上的接收误块率大于预设的第二门限值的情况下，确定所述终端移出所述广播业务的覆盖区域；
所述终端进入不支持所述广播业务的第一小区的覆盖区域。
也就是说，如果终端检测到广播信道的信号强度低于预配置的第一门限值或者终端在广播信道上的接收误块率大于与配置的第二门限值，那么终端可以认为终端检测到移出所述广播业务的覆盖区域，也就是满足预设条件。
另外，前述第一小区是否支持所述广播信息，可以通过所述第一小区的系统消息来确定；其中，所述第一小区的系统消息可以为SIB(系统信息块)、MIB(主信息块)中携带。
进一步来说，所述终端进入第一小区的覆盖范围内，接收所述第一小区的基站(或其他网络设备发来的系统消息；所述终端从所述系统消息中提取所述第一小区支持的业务的相关信息；所述终端基于所述第一小区支持的业务的相关信息，判断所述第一小区是否支持原所述广播业务；若判断结果为支持，则不作处理，若判断结果为不支持，则可以确定为终端检测到移出所述广播业务的覆盖区域，也就是满足前述预设条件。
其中，所述业务的相关信息中可以包括有：业务的标识、业务的类型等内容。进而，终端可以通过业务的标识来判断第一小区所支持的业务是否为当前使用的所述广播业务；和/或，终端可以通过业务的类型判断第一小区支持的业务是否为广播业务，进而可以确定所述第一小区是否支持原广播业务。
所述终端检测到在第一时长之后，移出所述广播业务的覆盖区域的方式可以包括：
所述终端接收到当前所在小区的系统信息，确定终端在第一时长之后所要进入的相邻小区不支持所述广播业务。
也就是说，终端在当前小区内接收系统消息，可以通过其MIB或SIB获取至少一个相邻小区所对应的业务的相关信息；
所述终端根据自身移动信息确定在第一时长内所要进入的相邻小区；
结合所述终端所要进入的相邻小区对应的业务的相关信息，判断所述所要进入的相邻小区是否支持当前的广播业务，若支持，则不满足预设条件，不进行处理；若不支持，则所述终端检测到在第一时长之后，移出所述广播业务的覆盖区域，也就是说满足前述预设条件。
其中，所述第一时长可以为根据实际情况进行设置，可以设置的比较短，也就是说终端仅判断即将发生的情况，不会对未来较长时间之后的情况进行判断，比如第一时长可以为5s，或者10s又或者可以更短，比如50ms等等，这里不做穷举。
业务的相关信息的说明与前述相同，不做赘述。相应的，终端的自身移动信息可以为终端根据当前的移动速度、移动方向等预判出来在第一时长内所要接入的相邻小区。
所述终端接收到用于指示所述广播业务在第二时长内停止的通知信息，具体可以为：
所述终端接收到无线接入网(RAN，Radio Access Network)节点发来的用于指示在第二时长内停止的通知信息。相应的，所述网络设备向所述终端设备发送用于指示所述广播业务停止的通知信息。所述网络设备可以为RAN节点。
其中，所述RAN节点发来的所述通知信息可以包含有所述广播业务在第二时长内停止；所述通知信息在广播控制信道发送，或者，由寻呼消息携带、或者由专用信令携带。
需要指出的是，所述第二时长可以设置较短，也就是说RAN仅在广播业务即将停止之前一个较短的时间内为终端发起该通知信息。
还需要理解的是，上述预设条件同样适应于多播业务的检测，即终端检测所述的组中多播业务条件。
基于前述检测，则所述终端可以确定由接收第一业务(本示例中为广播业务)的数据切换至接收第二业务(本示例中为单播业务)的数据；相应的，如图中所示步骤32，终端会基于所要建立的针对所述单播业务的PDU会话的相关信息，发起PDU会话的建立。
具体来说，所述终端确定所要建立的针对单播业务的PDU会话的相关信息，可以包括以下几种方式：
方式1：所述终端的非接入层NAS根据AS的第一指示信息、以及预配置的URSP的信息，确定所要建立的PDU会话的相关信息；其中，所述PDU会话为单播业务的PDU会话。
具体来说，
终端的NAS层根据AS的第一指示信息确定建立的PDU会话连接。
其中，所述第一指示信息中包含以下至少之一：所述单播业务对应的业务信息，所述单播业务所属的组信息，所述单播业务对应的切片信息。也就是说，所述AS的第一指示信息包含至少一种：广播业务信息，所属的组信息，切片信息。
相应的，终端的NAS层根据AS的第一指示信息以及预配置的URSP的信息，确定所需建立的针对单播业务的PDU会话的相关信息。
其中，所述PDU会话的相关信息中包括以下至少之一：DNN信息，组信息，切片信息等。
方式2：所述终端的非接入层NAS根据应用层的第二指示信息、以及预配置的URSP的信息，确定所要建立的PDU会话的相关信息；其中，所述PDU会话为单播业务的PDU会话。所述第二指示信息用于触发NAS建立所述PDU会话。
所述终端的应用层根据AS的第三指示信息；
所述第三指示信息，用于指示所述广播业务已经停止或即将停止。
比如可以为较短的时间，10ms等等。也就是说，终端的AS层向应用层指示广播业务即将停止或者当前特定组的业务即将停止。
终端的应用层根据AS的指示信息触发NAS层建立PDU会话。然后，终端的应用层将需要建立PDU会话的业务信息发送给NAS层，其中，可以包括例如业务信息，IP信息，组信息等。相应的，终端的NAS层根据URSP信息确定所需要建立的PDU会话的相关信息。
需要指出的是，图中示出发起PDU会话的建立需要网络侧设备的配合处理，比如图中的RAN、AMF、SMF以及UPF等实体。当然，图中仅为示例，本示例中不对具体建立单播业务的PDU会话的流程进行限定。
进一步地，基于前述说明，步骤33：当终端接收到此PDU会话的DRB配置，则终端停止广播业务的接收；相应的，所述网络设备收到所述终端设备发送的停止所述广 播业务的接收的信息。
另外，所述终端还会基于所述PDU会话的相关信息建立单播业务的连接，所述终端由广播业务切换至单播业务，通过单播业务进行后续单播业务的处理。
单播的传输方式，简单说明如下：
5GC支持PDU连接业务，PDU连接业务就是UE和DN之间交换PDU数据包的业务；PDU连接业务通过UE发起PDU会话的建立来实现。一个PDU会话建立后，也就是建立了一条UE和DN的数据传输通道。
每个S-NSSAI的订阅信息可能会包含一个默认DNN和多个DNN，当UE发起PDU Session Establishment Request(PDU会话建立请求)时没有提供S-NSSAI的DNN，那么服务AMF就会为其S-NSSA选择默认DNN，如果UE的订阅信息有默认DNN的话；如果没有默认DNN，那么服务AMF会选择本地配置的DNN给S-NSSAI。如果UE在PDU会话建立请求消息里携带的DNN不被网络支持，并且AMF也没能通过查询NRF选择到一个合适SMF，则AMF就会拒绝这个PDU连接请求，携带原因值“DNN is not supported”。
每个PDU会话支持一个PDU会话类型，也就是IPv4、IPv6、IPv4v6、Ethenet(以太网)、Unstructured中的一种。
PDU会话在终端和SMF实体之间通过NAS SM信令进行建立、修改、释放。
示例2：
本示例与上述示例1不同在于，本示例中第一业务为单播业务、第二业务为广播业务；进一步地，本示例中广播业务可以为正在采用单播承载进行传输的广播业务。也就是说，本示例针对了单播到广播的切换过程-终端移动到广播覆盖范围的业务切换的处理。
在本实施例中，终端在没有广播覆盖的区域通过单播传输业务，当终端检测到存在广播业务时，通知网络释放所对应的单播连接。下面结合图4对本示例进行详细说明：
步骤41：终端检测到广播业务则确定满足预设条件，又或者，终端进一步确定检测到的所述广播业务正在采用单播承载进行传输，则为满足预设条件，进而，所述终端确定由单播业务切换为广播业务。也就是说，本示例中，所述预设条件，包括：所述终端检测到存在广播业务。

方式2：终端的接入层根据前述预设条件中包含的至少之一检测到任一广播业务。
步骤42：终端检测到相关的广播业务之后，指示网络释放或去激活所述单播业务。
具体的，

关于前述停止所述单播业务的指示，可以理解为包括有释放或去激活所述单播业务对应的PDU会话连接的指示，或者，可以包括有删除所述单播业务对应的QoS数据流(Flow)的指示。
根据步骤41中的方式2：第四指示信息为：所监测到的广播业务的相关信息；其中，所述广播业务的相关信息包括以下至少之一：所属的组信息，切片信息。
相应的，所述终端的NAS层根据所属信息和URSP中的信息确定需要释放或者去激活的PDU会话。
具体来说，NAS向核心网发起PDU会话释放或者去激活过程，相应的，所述核心网设备根据终端的NAS发起的释放或去激活所述单播业务对应的PDU会话连接的处理，或者，请求删除所述单播业务对应的服务质量QoS数据流，所述核心网设备通知RAN节点释放或去激活所述单播业务对应的PDU会话连接、或者删除所述单播业务对应的服务质量QoS数据流。
其中，所述核心网设备通知RAN节点释放或去激活所述单播业务对应的PDU会话连接，包括：
所述核心网设备通知RAN节点释放或去激活单播业务对应的PDU会话连接的AN资源以及上下文信息。
需要指出的是，所述终端的AS根据NAS的指示进行单播业务所对应的广播业务的相关信息进行监测。具体的，所述单播业务主要针对了所述单播业务的PDU会话。也就是在单播业务承载建立过程中，所述终端的AS根据NAS的指示对单播业务对应的广 播业务进行检测，得到广播业务对应的相关信息。
方式B:所述终端的NAS根据应用层的第五指示信息，向核心网发起释放或去激活所述单播业务对应的PDU会话连接的处理；其中，所述第五指示信息用于指示广播业务的相关信息。

相应的，所述核心网设备根据终端的NAS发起的释放或去激活所述单播业务对应的PDU会话连接的处理，所述核心网设备通知RAN节点释放所述单播业务对应的PDU会话连接。
其中，所述核心网设备通知RAN节点释放所述单播业务对应的PDU会话连接，包括：

方式C：所述终端的AS向无线接入网RAN节点发送第六指示信息；
其中，所述第六指示信息包括：请求释放的单播业务对应的DRB信息、或者请求释放或去激活的单播业务对应的PDU会话信息、或者请求删除所述单播业务对应的QoS数据流信息。
可以为：终端的AS层向RAN发送第六指示信息，具体的可以为请求释放的DRB信息或者PDU会话信息或者监测到的广播信道的业务信息。RAN接受到终端的第六指示信息之后，释放所请求的DRB或PDU会话对应的DRB和相关配置。可以包括有RAN节点根据第六指示信息释放或去激活单播业务对应的PDU会话信息，或者，根据第六指示信息删除单播业务对应的QoS数据流的信息。
具体来说，所述网络设备为RAN节点的情况下，所述方法还包括：
所述RAN节点接收所述终端发来的第六指示信息。

和/或，所述第六指示信息中，包括：检测到的广播业务对应的广播信道的测量结果时，所述方法还包括：所述RAN节点根据所述测量结果判断是否释放单播承载。也就是说，终端可以上报给RAN所检测到的广播信道的结果；相应的，RAN根据此结果判断是否释放单播承载。比如，测量结果表示当前单播业务质量超过预设质量门限值(比如SIRN高于对应的门限值等等)，那么可以不释放单播业务对应的承载，否则，可以确定释放单播业务对应的承载，然后建立单播业务对应的广播业务的承载。
另外，所述RAN节点在单播业务的承载建立过程中，还会接收来自核心网指示对应的广播业务信息。
步骤43：所述终端由单播业务切换至广播业务。进而所述终端进行广播业务的建立。
如图5所示，网络侧在广播业务的区域内采用点到多点的传输方式发送下行数据。在这个区域中的终端可以采用广播信道接收广播数据。比如，图中广播业务由AF的业务层发起，通知给PCF实体，然后PCF实体选取对应的SMF或AMF实体；通过N7通道向SMF实体发送对应的业务建立请求(或者业务修改请求)；SMF实体进行RAN和/或UPF的选择之后，通过AMF实体与RAN节点进行广播业务的发送。
可见，通过采用上述方案，就能够结合终端设备的情况确定将终端的业务由当前的第一业务切换至第二业务。如此，能够使得终端在满足一定条件的情况下，实现业务之间的切换，从而保证了终端侧业务的连续性。
