具体而言，所述终端设备可以根据所述多个核心网支持的业务信息，以 及所述终端设备待接入业务的业务类型，确定需要跟哪些核心网建立连接，例如，所述终端设备待接入业务的业务类型为语音业务，若第一核心网支持语音业务，第二核心网支持视频业务，第三核心网支持短信业务，那么所述终端设备可以选择第一核心网为所述终端设备需要建立连接的核心网。
可选地，所述终端设备也可以根据所述终端设备的业务优先级信息以及所述多个核心网支持的业务信息确定需要建立连接的核心网，例如，若所述终端设备的语音业务的优先级高于视频业务的优先级，若第一核心网支持语音业务，第二核心网支持视频业务，那么在只能连接一个核心网的情况下，所述终端设备可以优先与第一核心网建立连接，即确定第一核心网为所述终端设备需要建立连接的核心网。
可选地，所述终端设备也可以根据接入网支持的核心网类型，以及所述多个核心网支持的业务信息确定需要建立连接的核心网，例如，若接入网支持第一核心网和第二核心网，所述终端设备可能传输的业务为第一业务和第二业务，若第一核心网和第三核心网支持第一业务和第二业务，那么所述终端设备可以确定第一核心网为所述终端设备需要建立连接的核心网。

所述终端设备根据所述多个核心网支持的业务信息，以及所述终端设备当前的业务需求、所述终端设备的业务优先级信息和接入网支持的核心网类型中的至少一项，确定需要建立连接的核心网。
例如，所述终端设备可以根据多个核心网支持的业务信息以及所述终端设备当前的业务需求确定需要跟哪些核心网建立连接，具体地，所述终端设备可以确定支持当前待接入业务的核心网为需要建立连接的核心网。
再例如，所述终端设备可以根据所述多个核心网支持的业务信息和所述终端设备的业务优先级信息确定需要跟哪些核心网建立连接，例如，所述终端设备可以根据所述终端设备的业务优先级信息，确定支持优先级最高的一个或多个业务的核心网为所述终端设备需要建立连接的核心网。
再例如，所述终端设备可以根据所述多个核心网支持的业务信息，所述终端设备当前的业务需求以及所述终端设备的业务优先级信息确定需要跟哪些核心网建立连接。例如，所述终端设备当前需要接入第一业务和第二业务，第一业务的优先级高于第二业务，其中，支持第一业务的核心网为第一核心网，支持第二业务的核心网为第二核心网，那么若只能连接一个核心网， 所述终端设备可以确定第一核心网为所述终端设备需要建立连接的核心网。
或者，所述终端设备也可以根据多个核心网支持的业务信息，所述接入网支持的核心网类型以及所述终端设备当前的业务需求，确定需要建立连接的核心网，例如，所述终端设备当前需要接入第一业务和第二业务，第一核心网支持第一业务，第二核心网支持第二业务，若接入网只支持第一核心网，也就是说，即使与第二核心网建立连接，也不能进行第二业务的传输，因此，所述终端设备可以确定第一核心网为所述终端需要建立连接的核心网。因此，本申请实施例的接入网络的方法，所述终端设备在确定需要跟哪些核心网建立连接时，可以综合考虑接入网支持的核心网类型，从而能够避免接入网设备不支持确定的需要建立连接的核心网，进而不能实现业务的有效接入的问题。

所述终端设备确定支持优先级最高的至少一个待接入业务的核心网为所述终端设备需要建立连接的核心网。
例如，所述终端设备当前需要接入第一业务和第二业务，所述第一业务的优先级高于所述第二业务，在只能接入一个核心网的情况下，所述终端设备优先确定支持所述第一业务的核心网为所述终端设备需要建立连接的核心网。
也就是说，所述终端设备可以根据终端设备当前的业务需求，业务优先级信息以及多个核心网支持的业务信息，确定需要跟哪些核心网建立连接。在需要接入的业务较多的情况下，根据需要接入的业务的优先级，确定支持优先级较高的业务的核心网为需要建立连接的核心网。

也就是说，所述终端设备可以根据终端设备当前的业务需求，接入网支持的核心网类型以及多个核心网支持的业务信息，确定需要跟哪些核心网建立连接。因此，所述终端设备在确定需要跟哪些核心网建立连接时，可以综合考虑接入网支持的核心网类型，从而能够避免接入网设备不支持确定的需要建立连接的核心网，进而导致业务不能有效接入的问题。
可选地，在本申请实施例中，所述终端设备也可以先根据接入网支持的核心网类型在所述多个核心网中确定至少一个核心网，然后在所述至少一个核心网中，确定支持当前的待接入业务的核心网，例如，所述多个核心网包括第一核心网、第二核心网和第三核心网，所述接入网支持第一核心网和第二核心网，若所述终端设备待接入第一业务和第二业务，其中，第一核心网支持第一业务，第三核心网支持第二业务，那么所述终端设备可以先根据接入网支持的核心网确定出第一核心网和第二核心网，然后在第一核心网和第二核心网中确定支持待接入业务的核心网，由于第一核心网支持第一业务，那么所述终端设备可以确定第一核心网为需要建立连接的核心网。
可选地，在一些实施例中，所述方法200还包括：
所述终端设备接收所述接入网设备发送的广播消息，所述广播消息用于通知所述终端设备所述接入网设备支持的核心网类型以及每个核心网是否允许所述终端设备接入的信息。
即所述终端设备可以通过接入网设备发送的广播消息获知所述接入网设备支持的核心网类型及每个核心网是否允许所述终端设备接入的信息，从而在进行核心网选择时，所述终端设备可以优先选择接入网支持的核心网类型，或允许所述终端设备接入的核心网。
可选地，所述广播消息可以只发送一次，例如，所述广播消息可以是基于终端设备的某个消息发送的，或者，也可以是周期性发送的。
可选地，在一些实施例中，所述方法200还包括：

可选地，作为一个具体的实现方式，所述终端设备获取所述终端设备的业务优先级信息，包括：
所述终端设备接收第一核心网发送的第二消息，所述第二消息包括所述终端设备的业务优先级信息，所述第一核心网为所述多个核心网中的任一核心网。
例如，所述终端设备可以从所述第一核心网获取终端设备的业务优先级信息，其中，所述第二消息和前述的第一消息可以为同一消息，或者也可以为不同的消息，即所述终端设备可以通过同一消息获取所述终端设备的业务优先级信息和所述第一核心网支持的业务信息，也可以通过不同的消息获知上述两种信息，本申请实施例对此不作限定。
跟所述第一消息类似，所述第二消息也可以为现有的用于核心网和终端设备之间进行通信的消息，例如，可以在现有的消息中新增属性字段，在新增属性字段中携带终端设备的业务优先级信息，或者所述第二消息也可以为新增的消息，本申请实施例对此不作限定。
可选地，在S220之后，所述方法200还包括：
所述终端设备向接入网设备发送第三消息，所述第三消息包括所述终端设备确定的需要建立连接的至少一个核心网的核心网类型信息和/或核心网标识信息。
作为示例而非限定，该核心网类型信息可以为公众陆地移动网(Public Land Mobile Network，PLMN)标识，所述核心网标识信息可以为唯一标识核心网的标识信息，由于一个核心网类型可能有多个核心网设备，因此，可以根据核心网标识信息唯一标识需要与哪个核心网设备建立连接。
可选地，所述第三消息可以为现有的用于终端设备和接入网设备之间进行通信的消息，例如，无线资源控制(Radio Resource Control，RRC)消息，具体的，可以在现有的消息中新增属性字段，在新增属性字段中携带所述至 少一个核心网的核心网类型信息和/或核心网标识信息，或者所述第三消息也可以为新增的消息，本申请实施例对此不作限定。
因此，本申请实施例的接入网络的方法，在确定需要建立连接的核心网时，所述终端设备可以根据多个核心网支持的业务信息，确定能够建立连接的核心网，从而能够实现终端设备对接入网的选择，并且，由于终端设备是基于多个核心网支持的业务信息进行选择的，因此，能够实现终端设备的业务的有效接入。
