步骤702f3，AMF在身份验证成功时，将AMF上的预配置的本地化服务信息发送给终端设备。
可选的，在本公开的一些实施例中，AMF接收终端设备发送的分组数据单元PDU会话建立请求。其中，PDU会话建立请求是由终端设备根据本地化服务信息发起的。SMF接收AMF转发的PDU会话建 立请求，并根据PDU会话建立请求创建终端设备的会话上下文。SMF从策略控制功能PCF获取策略相关信息，并选择用户面功能UPF以建立从无线接入网RAN到UPF的用户面隧道。SMF将会话相关配置参数和服务质量QoS参数发送给AMF。AMF将会话相关配置参数和服务质量QoS参数转发给终端设备，以建立本地化服务的PDU会话，以接入本地化服务。
通过实施本公开实施例，通过AMF将本地化服务信息发送给终端设备，通过终端设备根据该本地化服务信息选择目标托管网络，以便通过目标托管网络向终端设备提供本地化服务，可以解决终端设备如何获取本地化服务的问题，从而使得终端设备可以使用托管网络提供的本地化服务。
为了便于理解本公开，下面将结合图8对本公开实施例进行详细描述。
举例而言，如图8所示，本公开实施例的通过托管网络提供本地化服务的方法可包括但不限于如下步骤。
在步骤1中，UE通过当前第一网络中的(R)AN向当前第一网络中核心网的AMF发送注册请求，注册类型为“SNPN Onboarding”。为了允许UE接入SNPN，以便向UE提供来自订阅所有者SNPN(Subscribe-Owner-SNPN)的特定本地化服务信息。
在步骤2中，根据SNPN入网指示(Onboarding indication)，AMF选择AUSF进行身份验证/安全过程。
在步骤3中，UE和DCS之间通过AMF/AUSF执行认证/安全过程，当认证成功时，DCS通过AUSF向AMF发送本地化服务信息。
在步骤4中，AMF通过(R)AN向UE发送携带有本地化服务信息的注册接受消息。其中，在本实施例中，该本地化服务信息来源于DCS。
在步骤5中，UE/用户通过使用本地化服务信息来确定特定的本地化服务并选择相应的托管网络(即选择目标托管网络)。
在步骤6中，UE通过使用本地化服务信息(例如，本地化服务名称/FQDN等)来触发建立限制本地化服务的PDU会话。例如，UE根据本地化服务信息发起PDU会话建立请求。UE通过(R)AN/AMF向SMF(Session Management function，会话管理功能)发送该PDU会话建立请求，其中该请求中包含一些业务的需求。SMF创建UE的会话上下文，SMF从PCF(Policy Control function，策略控制功能)获取策略相关的信息。之后SMF选择一个合适的UPF(User plane function，用户面功能)以建立从RAN到UPF的用户面隧道。然后SMF通过AMF将会话相关的配置参数及QOS(Quality of Service，服务质量)参数等发送到RAN及UE。其中，AMF、AUSF、SMF、PCF和UPF均为该核心网中的网元。
值得注意的是，如果在步骤5中，UE选择另一网络作为托管网络，则UE将执行步骤1-4以进行注册。在成功认证之后，UE触发建立限制本地化服务的PDU会话。
在本公开中，在终端设备和DCS之间通过托管网络(SNPN)进行认证之后，AMF通过AUSF从DCS获得本地化服务信息并发送给终端设备。终端设备通过本地化服务信息触发经由托管网络为本地化服务建立受限PDU会话，可以增强UE入网操作期间的配置过程，解决终端设备如何获取本地化服务的问题，从而使得终端设备可以使用托管网络提供的本地化服务。
