具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例提供的业务请求方法进行详细说明之前，先对公共网络和非公共网络进行简要说明。
在长期演进(Long Term Evolution，LTE)网络和新无线(New Radio，NR)网络中，通常部署公共网络，即公共陆地移动网络(Public Land Mobile Network，PLMN)。但是，在一些场景中，如办公场景、家庭场景、工厂等，为了能够更加有效的进行网络安全管理，通常会部署本地网络或私有网络；本地网络和私有网络也称为非公共网络。
终端设备的部分业务仅能够在公共网络中实现，如IP多媒体(IP Multimedia Subsystem，IMS)业务。因此，在实现IMS业务时，驻留在非公共网络中的终端设备需要接入到公共网络中。驻留在非公共网络中的终端设备接入到公共网络的示意图，如图1所示，终端设备通过NPN接入到PLMN网络的过程为，终端设备通过NPN网络中的用户面功能(User Plane Function，UPF)实体建立与PLMN中非3GPP互通功能(Non-3GPP InterWorking Function，N3IWF)实体之间的数据传输通道，使得终端设备能够与PLMN中的接入和移动管理功能(Access and Mobility Management Function，AMF)实体、UPF实体等PLMN实体进行交互。但是，在某些场景下，PLMN网络的NR系统肯不支持终端设备待传输的业务，但是PLMN网络的LTE系统能够支持终端设备待传输的业务，如IMS语音业务。在该场景下，驻留在非公共网络中的终端设备需要接入到LTE系统。
终端设备可通过非3GPP网络接入LTE系统，终端设备通过非3GPP网络接入LTE系统的一种示意图，如图2所示，终端设备首先建立与ePDG之间的数据传输链路，ePDG也建立与PDN GW之间的数据传输链路，终端设备发送的数据通过ePDG发送到PDN GW，通过PDN GW发送到运营商的业务域。终端设备通过非3GPP网络接入LTE系统的另一种示意图，如图3所示，终端设备建立与PDN GW之间的数据传输链路，，终端设备发送的数据首先发送到PDN GW，再由PDN GW发送到运营商的业务域。
本申请提供一种业务请求方法，本申请实施例的业务请求方法可通过3GPP非公共网络接入到公共网络，，本申请实施例的业务请求方法可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、LTE系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
