本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。本申请实施例中以提供的方法应用于NR系统或第五代移动通信技术(5th generation mobile networks或5th generation wireless systems、5th-Generation，5G)网络中为例进行说明。
在介绍本申请实施例之前首先对本申请实施例涉及到的相关名词作如下释义：
1)、公共网络，指为公众提供陆地移动通信业务目的而建立和经营的网络，即传统的运营商网络，包括但不限于手机通信。例如，公共网络可以为公共陆地移动网络(public land mobile network，PLMN)。
2)、非公共网络(Non-public network，NPN)，是一种非公用的5G网络，指可以供部分私 有用户使用的通信网络。例如，非公共网络可以包括工业通信网络、企业私有网络等，其中典型的工业通信网络服务范围通常为一个或者多个工业园区，企业私有网络服务范围通常为一个企业内部的所有用户。换言之，非公共网络只服务于某工业通信网络、企业私有网络所管理或拥有的设备，为这些设备提供数据连接等网络通信服务。
举例说明，非公共网络为某个工业园区提供通信服务，则该非公共网络可以为位于该工业园区，且为具有接入该非公共网络的能力和权限的终端提供通信服务。
本申请实施例中的非公共网络也可以称为：私网或者专用网络，此处统一说明，后续不再赘述。
非公共网络可以包括：公网集成NPN(public network integrated NPN，PNI-NPN)以及独立部署NPN(standalone NPN，SNPN)。其中，公网集成NPN可以依赖PLMN的支持实现，SNPN不依赖与PLMN的网络功能实现。
公网集成NPN可以使用PLMN中的网络切片实现，为了阻止非授权终端尝试接入和选择PNI-NPN，额外使用封闭访问组(closed access group，CAG)功能。CAG用于识别一组终端。能够被CAG识别的一组终端允许接入与CAG关联的小区(CAG小区)。为了防止不允许接入CAG小区的终端自动选择和接入CAG小区，CAG小区广播一个或者多个CAG标识，终端上配置可用的CAG列表(list)和指示(该指示用于指示终端是否只允许通过CAG小区接入5G系统(5G System，5GS))。统一数据管理网元中具有该终端的签约数据，该终端的签约数据中包括该终端可用的CAG list和指示。
如图1中的(a)图所示：图1中的(a)图以公网集成NPN为例，其中，基站1发送系统信息块(system information block，SIB)1，该SIB1中包括：PLMN ID＝A，CAG标识＝X。基站2发送SIB2，该SIB2包括：PLMN ID＝A。终端1上具有的PLMN ID＝A，CAG标识＝X；终端2上具有的PLMN ID＝A，CAG标识＝X，以及只能通过CAG小区接入5G系统的指示；终端3上具有的PLMN ID＝A，则终端1既可以接入基站1也可以接入基站2，而终端2虽然能接入基站1，但不能接入基站2。终端3可以接入基站2，但是终端3不能接入基站1。
如图1中的(b)图所示：图1中的(b)图以独立部署NPN为例，SNPN(5G网络)独立部署，不依赖PLMN，SNPN使用PLMN ID+NID来标识，其中PLMN ID可以为第三方运营商预留的固有值，也可以是部署此SNPN的PLMN运营商的特定值。在SNPN中，SNPN中的基站3发送SIB3，该SIB3包括该SNPN的标识N(例如，PLMN ID+NID1)。终端4根据广播信息和配置的选网信息选择接入的NPN网络。如果终端4发现配置的选网信息(PLMN ID+NID2)与基站3广播的PLMN ID或者PLMN ID+NID1不相同，终端4不会选择接入该SNPN。如果终端4发现配置的选网信息(PLMN ID+NID1)与基站3广播的PLMN ID或者PLMN ID+NID1相同，终端4选择接入该SNPN。
图1中的(a)图描述的架构和图1中的(b)图描述的架构不支持切换。基站1、基站2以及基站3可以为5G网络中的基站。例如，基站1、基站2以及基站3可以为下一代节点B(next Generation Node B，gNB)。图1中的(a)图以基站1和基站2接入相同的5G核心网(5G Core，5GC)为例。基站2接入非公共网络对应的5GC。
如图2所示，图2示出了公共网络或者非公共网络的构成，无论公共网络或者非公共网络均包括终端、接入网(acess network，AN)、核心网(core)和数据网络(data network，DN)，其中，终端，AN，Core是构成架构的主要成分，逻辑上终端，AN，Core可以分为用户面和控制面 两部分，控制面负责移动网络的管理，用户面负责业务数据的传输。图2中，NG2参考点位于AN的控制面和Core的控制面之间，NG3参考点位于AN的用户面和Core的用户面之间，NG6参考点位于Core的用户面和数据网络之间。
终端：是移动用户与网络交互的入口，能够提供基本的计算能力，存储能力，向用户显示业务窗口，接受用户操作输入。5G网络中的终端可以采用新空口技术，与AN建立信号连接，数据连接，从而传输控制信号和业务数据到移动网络。
AN：类似于传统网络里面的基站，部署在靠近终端的位置，为特定区域的授权终端提供入网功能。AN能够根据终端的级别，业务的需求等确定不同质量的传输隧道来传输终端的数据。AN能够管理自身的资源，合理利用，按需为终端提供接入服务，以及负责在终端和核心网之间转发控制信号和终端数据。
Core：负责维护移动网络的签约数据，管理移动网络的网元，为终端提供会话管理，移动性管理，策略管理，安全认证等功能。在终端附着的时候，该Core为终端提供入网认证。在终端有业务请求时，该Core为终端分配网络资源；在终端移动的时候，Core为终端更新网络资源。在终端空闲的时候，Core为终端提供快恢复机制；在终端去附着的时候，Core为终端释放网络资源；在终端有业务数据时，Core为终端提供数据路由功能，如转发上行数据到data network。或者Core从Data Network接收针对终端的下行数据。Core向AN发送接收到的针对终端的下行数据，以由AN向终端发送针对该终端的下行数据。
data network：是为用户提供业务服务的数据网络，一般客户端位于终端，服务端位于数据网络。数据网络可以是私有网络，如局域网，也可以是不受运营商管控的外部网络，如因特网(internet)，还可以是运营商共同部署的专有网络，如提供IP多媒体网络子系统(IP multimedia core network subsystem，IMS)服务的网络。
综上，图2描述了非公共网络和公共网络的主要构成部分，如图3所示，图3示出了本申请的一种网络的接入方法适用的通信系统，该通信系统包括：终端10、以及接入管理网元20。该接入管理网元20属于非公共网络100中的网元。
其中，终端10可以通过非公共网络100中的接入网设备30以及接入管理网元20接入非公共网络100。
在本申请实施例中，终端10可以分布于无线网络中，每个终端可以是静态的或移动的。
在一种可能的实现方式中，该通信系统还可以包括：统一数据管理网元40。该统一数据管理网元40属于公共网络200中的网元。该公共网络200与非公共网络100之间互通。待终端10成功接入非公共网络100后。终端10可以通过非公共网络100接入该公共网络200。
本申请实施例中如图3所示的通信系统可以应用于目前的5G网络架构以及未来出现的其他网络架构，本申请实施例对此不做限定。
下述以图3所示的通信系统适用于5G网络为例，即非公共网络100和公共网络200均为5G网络为例，该接入管理网元20对应的网元或者实体可以为如图3所示的：接入与移动管理功能(access and mobility management function，AMF)网元。统一数据管理网元40对应的网元或者实体可以为统一数据管理(unified data management，UDM)网元。接入网设备30对应的网元或者实体可以为(无线)接入网((radio)access network，(R)AN)设备。
如图4所示，图4示出了非公共网络100或公共网络200中还可以包括：会话管理功能(session management function，SMF)网元、策略控制功能(policy control function，PCF)网元、网络切 片选择功能(network slice selection function，NSSF)网元、认证服务器功能(authentication server function，AUSF)网元、网络能力开放功能(network exposure function，NEF)网元、网络仓库贮存功能(network repository function，NRF)网元、以及应用功能(application function，AF)网元等，本申请实施例对此不作具体限定。
如图5a所示，该非公共网络100或公共网络200还可以与数据网络(data network，DN)通信，该DN可以由AF网元管理。
其中，终端通过(R)AN设备接入网络(非公共网络或者公共网络)，终端通过N1接口(简称N1)与AMF网元通信。SMF网元通过N4接口(简称N4)与一个或者多个UPF网元通信。UPF网元通过N6接口(简称N6)与DN通信。(R)AN设备与AMF网元之间通过N2接口(简称N2)通信。(R)AN设备通过N3接口(简称N3)与UPF网元通信。其中，控制面网元也可以采用服务化接口进行交互。例如，如图4所示，AMF网元、SMF网元、UDM网元、或者PCF网元采用服务化接口进行交互。比如，AMF网元对外提供的服务化接口可以为Namf。SMF网元对外提供的服务化接口可以为Nsmf。UDM网元对外提供的服务化接口可以为Nudm。PCF网元对外提供的服务化接口可以为Npcf。NSSF网元对外提供的服务化接口可以为Nnssf。NEF网元对外提供的服务化接口可以为Nnef。AF网元对外提供的服务化接口可以为Naf。应理解，各种服务化接口的名称的相关描述可以参考现有技术中的5G系统架构(5G system architecture)图，在此不予赘述。
如图4所示的网络架构中，以控制面网元采用服务化接口进行交互为例，当然控制面网元也可以采用如下方式进行通信：AMF实体通过N11接口(简称N11)与SMF网元通信。一个或多个UPF网元中任意两个UPF网元通过N9接口(简称N9)通信。SMF网元通过N7接口(简称N7)与PCF网元通信，PCF网元通过N5接口与AF网元通信。任意两个AMF网元之间通过N14接口(简称N14)通信。SMF网元通过N10接口(简称N10)与UDM通信。AMF网元通过N12接口(简称N12)与AUSF通信。AUSF网元通过N13接口(简称N13)与UDM网元通信。AMF网元通过N8接口(简称N8)与UDM网元通信。
需要说明的是，图4仅是示例性的给出一个UPF网元、SMF网元。当然，该中可能包括多个UPF网元、SMF网元，如包括SMF网元1和SMF网元2，本申请实施例对此不作具体限定。
需要说明的是，图4的(R)AN设备、AMF网元、SMF网元、UDM网元、UPF网元和PCF网元等仅是一个名字，名字对设备本身不构成限定。在5G网络以及未来其它的网络中，(R)AN设备、AMF网元、SMF网元、UDM网元、UPF网元和PCF网元所对应的网元或实体也可以是其他的名字，本申请实施例对此不作具体限定。例如，该UDM网元还有可能被替换为用户归属服务器(home subscriber server，HSS)或者用户签约数据库(user subscription database，USD)或者数据库实体，等等，在此进行统一说明，后续不再赘述。
由于在第三代合作伙伴计划(3rd generation partnership project，3GPP)的不同版本中，非公共网络与公共网络互通的方式存在差异，因此下述将结合图5a和图5b分别介绍：
在3GPP的第一版本中，如图5a所示，非公共网络100与公共网络200采用基于非3GPP互通功能(Non-3GPP interworking function，N3IWF)的架构进行互通，这时终端10具有双签约信息，即终端10不仅具有与非公共网络100之间的私网签约信息还具有与公共网络200之间的第一公网签约信息。其中，私网签约信息用于终端10接入非公共网络100。第一公网签约信息用于指定10接入公共网络200。应理解，终端10与非公共网络100之间的私网签约信息中包括该终端 10的标识1，该终端10的标识1中包括非公共网络100的标识。终端10与公共网络200之间的第一公网签约信息中包括该终端10的标识2，该终端10的标识2中包括公共网络200的标识。
例如，第一版本可以为版本(Release，R)16。
如图5a所示：终端10使用与非公共网络100之间的私网签约信息确定非公共网络100的标识。然后终端10接入非公共网络100中部署的接入网设备，终端10通过接入网设备在非公共网络100中进行3GPP注册。终端10使用与公共网络200之间的第一公网签约信息确定公共网络200的标识。之后，终端10选择公共网络200中的N3IWF，终端10在非公共网络100建立PDU会话接入公共网络200中的N3IWF，在公共网络200网络进行N3GPP注册。
具体的，如图5a所示，非公共网络100中包括AMF网元1、SMF网元1、以及UPF网元1，公共网络200中包括AMF网元2、SMF网元2、UPF网元2以及N3IWF。其中，N3IWF用于实现非公共网络100与公共网络200之间的互通。
终端10通过NPN的3GPP接入技术(access technology)接入非公共网络100，之后终端10与非公共网络100网络中的UPF网元1之间建立PDU会话。后续待终端10需要通过非公共网络100网络在公共网络200网络进行非3GPP(non 3GPP，N3GPP)注册时，终端10可以利用与UPF网元1之间建立的PDU会话向UPF网元1发送公网的注册请求消息，该公网的注册请求消息用于请求在公共网络200中注册该终端10。之后，UPF网元1利用如图5a所示的DN1向N3IWF发送公网的注册请求消息。在N3IWF接收到公网的注册请求消息之后，可以将公网的注册请求消息转发给公共网络200中的AMF网元2，以由AMF网元2根据公网的注册请求消息判断是否允许该终端10在公共网络200中注册。如果AMF网元2允许该终端10在公共网络200中注册，则向N3IWF发送注册接受消息，以由N3IWF将该注册接受消息通过DN1发送给非公共网络100中的UPF网元1。UPF网元1接收到该注册接受消息之后可以利用与该终端10之间的PDU会话向该终端10发送该注册接受消息。可以理解的是，该DN1用于为非公共网络100提供服务，而DN2用于为公共网络200提供服务。即终端10可以通过非公共网络100访问DN1上部署的业务。即终端10可以通过公共网络200访问DN2上部署的业务。
需要说明的是，图5a所示的非公共网络100以及公共网络200中涉及到的各个网元之间的通信接口可以参考图4处的描述，此处不再赘述。如图5a所示，N3IWF与DN之间通过N6接口通信。N3IWF与AMF网元2之间通过公共网络的N2接口通信。
在3GPP的第二版本(第二版本为第一版本的升级版本)中，如图5所示，非公共网络100与公共网络200采用漫游架构互通，这时终端10具有与公共网络200之间的第二公网签约信息。如图5b所示：终端10使用与公共网络200之间的第二公网签约信息确定非公共网络100的标识。待终端10确定非公共网络100的标识之后，终端10可以选择利用该非公共网络中部署的(R)AN设备实现在非公共网络100中的注册。随后，终端10可以在非公共网络100中建立会话(例如，PDU会话)，非公共网络100根据第二公网签约信息确定会话的模式为归属路由(home routed，HR)模式或者为本地疏导(local breakout)模式。例如，第二版本可以为R17。
应理解，第二公网签约信息中包括允许该终端10接入的一个或多个非公共网络的信息。当该终端10位于某个非公共网络a的覆盖范围时，终端10可以接收到该非公共网络a的广播信息(包括该非公共网络a的标识)。如果广播信息中包括的非公共网络a的标识与一个或多个非公共网络的标识中的某个非公共网络的标识相同，则该终端10便可以确定能够选择该非公共网络a接入。
图5b以非公共网络100与公共网络200支持互通的漫游架构为归属路由模式为例，图5b中 该终端10的非公共网络100(又可以称为该终端的拜访地网络(visited network))包括：AMF网元1、拜访地SMF(visited SMF，V-SMF)网元、拜访地(visited PCF，V-PCF)网元、(R)AN设备、拜访地UPF(visited UPF，V-UPF)网元以及拜访地NSSF(visited NSSF，V-NSSF)网元。该终端10的公共网络200(又可以称为该终端的归属地网络(home network))包括：归属地SMF(home SMF，H-SMF)网元、归属地PCF(home PCF，H-PCF)网元、归属地UPF(home UPF，H-UPF)网元、UDM网元、AUSF网元以及归属地NSSF(home NSSF，H-NSSF)网元。
其中，H-SMF网元与V-SMF网元通过N16接口通信，AUSF网元与AMF网元1通过N12接口通信。H-PCF网元与V-PCF网元通过N24接口通信。AMF网元1与V-NSSF网元通过N22接口通信。V-NSSF网元与H-NSSF网元通过N31接口通信。H-UPF网元与V-UPF网元通过N9接口通信。
其中，公共网络200中还可以包括：归属地-安全边缘保护代理(home Security edge protection proxy，H-SEPP)。非公共网络100中还可以包括：拜访地-安全边缘保护代理(visited Security edge protection proxy，V-SEPP)。公共网络200和非公共网络100之间通过拜访地的SEPP和归属地的SEPP通信。归属地的SEPP和拜访地的SEPP之间具有N32接口。
本申请实施例中涉及到的公共网络可以为PLMN，非公共网络可以为SNPN，此处统一说明，后续不再赘述。

如图6所示，图6示出了本申请实施例提供的一种网络的接入方法的交互实施例，该方法包括：
步骤601、第一终端向第一非公共网络中的接入管理网元发送第一消息，相应的，第一非公共网络中的接入管理网元接收来自第一终端的第一消息。该第一消息用于请求在第一非公共网络中注册第一终端。
应理解，该第一终端位于该第一非公共网络的覆盖范围内。应理解，第一终端可以检测到一个或多个候选非公共网络，该第一非公共网络可以为一个或多个候选非公共网络中的任一个非公共网络。当然第一非公共网络可以为一个或多个候选非公共网络中的信号质量最强的候选非公共网络。
例如，接入管理网元可以为图2所示的接入管理网元20。第一非公共网络可以为图2中的非 公共网络100。
本申请实施例中的第一终端不具有接入非公共网络的权限或能力。当然该第一终端可以具有接入公共网络的权限或能力，本申请实施例对此不作限定。
需要说明的是，一方面，第一终端为不具有接入非公共网络的权限中的“非公共网络”可以为泛指，即该第一终端不具有接入任何非公共网络的权限。例如，无论非公共网络是非公共网络1还是非公共网络2，第一终端均不能接入。另一方面，第一终端为不具有接入非公共网络的权限中的“非公共网络”可以为特指，即该第一终端只是不能接入特定的非公共网络(例如，特定的非公共网络为第一非公共网络)，但是该第一终端可以接入除第一非公共网络以外的非公共网络。例如，以第一非公共网络为非公共网络1为例，第一终端虽然不具有接入非公共网络1的功能，但是第一终端具有接入非公共网络2的功能。
举例说明，第一终端专门用于接入为工厂1服务的非公共网络2，当第一终端位于为工厂2服务的非公共网络1的覆盖范围内时，该第一终端不具有接入该非公共网络1的权限。
作为一种可能的实现方式，该第一消息中还可以携带该第一终端的标识。该第一终端的标识用于识别该第一终端。例如，第一终端的标识可以为以下一个或者多个：签约永久标识(subscription permanent identifier，SUPI)、用户隐藏标识符(subscriber concealed identifier，SUCI)。下述实施例中但凡涉及到终端的标识均可以参考此处的描述，后续不再赘述。
作为一种具体实现，本申请实施例中的步骤601可以通过以下方式实现：第一终端通过第一非公共网络中的接入网设备向第一非公共网络中的接入管理网元发送第一消息。相应的，第一非公共网络中的接入管理网元通过第一非公共网络中的接入网设备接收来自第一终端的第一消息。可以理解的是，接入管理网元还可以从第一非公共网络中的接入网设备处获取该第一非公共网络的信息。例如，该第一非公共网络的信息用于识别该非公共网络。例如，该第一非公共网络的信息可以为该第一非公共网络的标识。以第一非公共网络的信息为第一非公共网络的标识为例，则第一非公共网络的标识由目标公共网络的标识和NID确定。
本申请实施例中的目标公共网络为与该第一非公共网络对应的公共网络。例如，以目标公共网络为A运营商的公共网络，如果A运营商为目标公共网络分配的目标公共网络的标识为“00000”，NID为“0001”，则第一非公共网络的标识包括“000000001”。换言之，目标公共网络的标识为部署第一非公共网络的运营商为该目标公共网络分配的特定值。或者，该目标公共网络的标识为第三方运营商为该目标公共网络预留的固有值，本申请实施例对此不做限定。
例如，第一消息可以为注册请求消息。
步骤602、接入管理网元向第一公共网络中的统一数据管理网元发送查询消息，相应的，第一公共网络中的统一数据管理网元接收来自非公共网络中的接入管理网元的查询消息。该查询消息用于查询第一终端的签约数据。
其中，第一公共网络与第一非公共网络互通，换言之，步骤601～步骤605中描述的第一非公共网络为与第一公共网络互通的非公共网络。
例如，查询消息中可以携带第一终端的标识以及该第一非公共网络的信息。
例如，第一公共网络可以为图2所示的公共网络200。统一数据管理网元可以为图2中的统一数据管理网元40。
步骤603、统一数据管理网元向接入管理网元发送第三消息，相应的，接入管理网元从第一公共网络中的统一数据管理网元处获取第三消息。该第三消息包括以下一项或多项：第一终端的 签约数据、原因值。
其中，签约数据中包括第二指示信息。一方面，该第二指示信息用于指示第一终端只能通过公共网络接入。或者，另一方面，第二指示信息用于指示第一终端不能通过非公共网络接入。该原因值表示不允许第一终端在第一非公共网络中接入。
需要说明的是，如果统一数据管理网元可以主动向接入管理网元发送第三消息，则步骤602可以省略。
应理解，上述第一终端只能通过公共网络接入中的“公共网络”为泛指，即该第一终端用于通过除非公共网络外的任何公共网络接入，并不局限于只能通过第一公共网络接入。上述第一终端不能通过非公共网络接入中的“非公共网络”可以为泛指，即该第一终端不能够通过任何非公共网络接入。上述第一终端不能通过非公共网络接入中的“非公共网络”为特指，即该第一终端不能够通过该第一非公共网络接入。本申请实施例对此不做限定。
步骤604、接入管理网元根据第三消息向第一终端发送第二消息，相应的，第一终端接收来自接入管理网元的第二消息。该第二消息用于表示拒绝第一终端在第一非公共网络进行注册。其中，第二消息包括第一指示信息，该第一指示信息表示禁止第一终端在第一非公共网络中接入。
步骤605、第一终端根据第一指示信息更新第一终端的网络禁选列表。其中，该更新后的网络禁选列表中包括第一非公共网络的信息。
当然该更新后的网络禁选列表可以看作为第一网络禁选列表。
作为一种可替代的方式，本申请实施例中的步骤605可以通过以下方式实现：第一终端根据第一指示信息将第一非公共网络的信息加入第一终端的网络禁选列表中。
可以理解的是，一方面，该第一终端的网络禁选列表中可能本身具有一个或多个网络的信息，该一个或多个网络中包括第一非公共网络，换言之，第一终端的网络禁止列表中可能包括该第一非公共网络。该一个或多个网络中每个网络具有一个记录项，该记录项用于表示该网络是被禁止接入的还是允许接入的。在这种情况下，该更新后的网络禁选列表中包括第一非公共网络的信息可以理解为：第一终端将第一非公共网络对应的记录项设置为被禁止接入状态。
所谓的第一终端更新第一终端的网络禁选列表可以指：第一终端更新网络禁选列表中第一非公共网络对应的记录项。
举例说明，第一非公共网络的记录项为指示符a，表示该第一非公共网络是被禁止接入的。第一非公共网络的记录项为指示符b，表示该第一非公共网络是被允许接入的。该网络禁选列表中包括第一非公共网络对应的记录项为指示符b，然后第一终端执行上述步骤601～步骤603以请求接入该第一非公共网络。但是第一终端在请求接入第一非公共网络的过程中接收到第二消息。第二终端根据第二消息确定被拒绝接入该第一非公共网络。之后第一终端可以将第一非公共网络对应的记录项设置为指示符a。
当然指示符a也可以使用去激活状态表示，指示符b也可以使用激活状态表示，本申请实施例对此不做限定。
当然，另一方面，该第一终端的网络禁选列表中可能本身具有一个或多个网络的信息，该一个或多个网络中不包括第一非公共网络，则该更新后的网络禁选列表中包括第一非公共网络的信息可以理解为：第一终端将第一非公共网络的信息加入该网络禁选列表，且设置该第一非公共网络对应的记录项为指示符a。
举例说明，以第一非公共网络为非公共网络1，第一终端不具有接入非公共网络1的权限为 例，当第一终端位于非公共网络1的覆盖范围时，第一终端可以利用非公共网络1中的接入网设备向非公共网络1中的接入管理网元发送第一消息，以请求在非公共网络1中注册，之后如果第一终端接收到来自接入管理网元的第二消息，如果第二消息表示拒绝该第一终端在非公共网络1中进行注册，则第一终端可以确定非公共网络1为第一终端禁止接入的非公共网络。
本申请实施例中第一非公共网络的信息用于识别第一非公共网络。例如，该第一非公共网络的信息可以为第一非公共网络的标识。当然，该第一非公共网络的信息还可以是其他可以标识该第一非公共网络的参数，本申请实施例对此不做限定。
本申请实施例提供一种网络的接入方法，该方法中第一终端通过向第一非公共网络中的接入管理网元发送第一消息，以请求在第一非公共网络中注册该第一终端。之后，第一终端接收来自接入管理网元的第二消息，该第二消息表示拒绝第一终端在第一非公共网络进行注册，且第一指示信息表示禁止第一终端在第一非公共网络中接入。以便于第一终端根据第一指示信息更新第一终端的网络禁选列表，使得更新后的网络禁选列表中包括第一非公共网络的信息，后续第一终端在选择网络注册时便可以避免选择被禁止接入的第一非公共网络。该方案可以解决不具有接入非公共网络的权限的第一终端尝试接入第一非公共网络的问题。
在一种可能的实施例中，本申请实施例提供的方法在步骤605之后还可以包括：第一终端根据更新后的网络禁选列表选择除第一非公共网络以外的网络进行注册。
作为一种具体实现，第一终端根据更新后的网络禁选列表选择除第一非公共网络以外的网络进行注册可以通过以下方式实现：第一终端根据更新后的网络禁选列表选择除更新后的网络禁选列表记载的网络进行注册。
举例说明，以第一非公共网络为非公共网络1为例，如果更新后的网络禁选列表中包括非公共网络1的信息，则第一终端可以选择非公共网络1以外的非公共网络2进行注册。如果更新后的网络禁选列表中包括非公共网络1的信息以及非公共网络2的信息，则第一终端可以选择除非公共网络1和非公共网络2以外的非公共网络3进行注册，该更新后的网络禁选列表中未包括非公共网络3的信息。
在一种可能的实施例中，本申请实施例提供的方法在步骤605之后还可以包括：第一终端根据第一指示信息启动定时器，在定时器超时的情况下，第一终端从更新后的网络禁选列表中删除第一非公共网络的信息。这样可以使得在定时器超时的情况下，第一非公共网络依然可以作为该第一终端能够选择接入的非公共网络。
应理解，定时器超时可以指达到该定时器对应的定时器时间值。
在一种可替代的实现方式中，上述第一终端从更新后的网络禁选列表中删除第一非公共网络的信息还可以通过以下方式替换：第一终端更新第一网络禁选列表，得到第二网络禁选列表。该第二网络禁选列表中不包括第一非公共网络的信息，或者该第二网络禁选列表中包括的第一公共网络对应的记录项表示该第一非公共网络为可接入的网络，本申请实施例对此不做限定。
结合上例，在定时器超时的情况下，第一终端将第一非公共网络对应的记录项从指示符a更新为指示符b。
可以理解的是，当第一终端从更新后的网络禁选列表中删除第一非公共网络的信息，则后续第一终端便可以继续请求在该第一非公共网络中注册。举例说明，针对不具有接入非公共网络的权限的第一终端，若该第一终端经过配置后具有接入非公共网络的权限，则在达到定时器对应的定时器时间值时，由于第一终端从网络禁选列表中删除第一非公共网络的信息，则后续第一终端 便可以在该第一非公共网络中注册。
需要说明的是，本申请实施例中从某个网络禁选列表中删除某个非公共网络的信息也可以表达为：第二终端将该非公共网络对应的记录项设置为指示符a。
本申请实施例中上述定时器对应的定时器时间值可以由协议预定义，或者该定时器对应的定时器时间值可以由第一终端自己配置，或者该定时器对应的定时器时间值可以由接入管理网元为该第一终端配置。
在由接入管理网元为该第一终端配置定时器对应的定时器时间值的情况下，第二消息包括定时器时间值，相应的，第一终端根据定时器时间值设置定时器。当然，该接入管理网元还可以通过除第二消息以外的其他消息向第一终端发送定时器对应的定时器时间值，本申请实施例对此不做限定。
如图6所描述的实施例可以适用于如下场景：
场景1、第一非公共网络和第一公共网络均为第一版本中定义的网络，例如，第一非公共网络为R16非公共网络，第一公共网络为R16公共网络。
场景2、第一非公共网络和第一公共网络均为第二版本中定义的网络，例如，第一非公共网络为R17非公共网络，第一公共网络为R17公共网络。此时，接入管理网元可以为如图5b中的AMF网元1。
在场景1和场景2中当第一非公共网络和第一公共网络之间不支持互通的情况下，步骤605可以省略。此时，第二消息中的第一指示信息可以由指示信息x替换，其中，指示信息x用于指示禁止该第一终端在第一非公共网络中接入的原因为：该第一终端为非法终端。第一终端为非法终端表示该第一非公共网络无法识别该第一终端的身份。
在场景2中当第一非公共网络和第一公共网络之间支持互通的情况下，步骤605为必选步骤。
需要说明的是，如果第一非公共网络为R17非公共网络，第一公共网络为R17公共网络，则第一非公共网络与第一公共网络采用漫游架构互通。
如图7所示，图7示出了本申请实施例提供的一种网络的接入方法的交互实施例，该方法包括：
步骤701、第一非公共网络中的接入网设备发送广播信息，相应的，第二终端接收来自第一非公共网络中的接入网设备的广播信息。该广播信息包括第一指示信息，该第一指示信息用于指示第一非公共网络与公共网络互通。
本申请实施例中的第二终端为具有接入非公共网络功能的权限。当然该第二终端可以具有接入公共网络的权限，或者该第二终端也可以不具有接入公共网络的权限，本申请实施例对此不作限定。
需要说明的是，一方面，第二终端为具有接入非公共网络的权限中的“非公共网络”可以为泛指，即该第二终端具有接入任何非公共网络的权限。例如，无论非公共网络是非公共网络1还是非公共网络2，第二终端均能够接入。另一方面，第二终端为具有接入非公共网络的权限中的“非公共网络”可以为特指，即该第二终端只能够接入特定的非公共网络(例如，特定的非公共网络为第一非公共网络)。
可以理解的是，第一非公共网络与公共网络互通中的“公共网络”可以为泛指的任何公共网络。
应理解，该第二终端位于第一非公共网络的覆盖范围内，且该第二终端能够接收到来自第一 非公共网络中的接入网设备发送的广播信息。
示例性的，第一指示信息可以为第一指示符，该第一指示符用于表示第一非公共网络与公共网络互通。例如，第一指示信息可以为“1”。
作为一种具体实现，该第一指示信息用于指示第一非公共网络与公共网络使用漫游架构互通。以便于第二终端使用漫游架构接入该第一非公共网络。所谓第二终端使用漫游架构接入该第一非公共网络可以指：第二终端使用该第二终端在公共网络中的签约信息(例如，下述第一签约信息)接入该第一非公共网络。
在一种可能的实现方式中，本申请实施例中的方法在步骤701之前还可以包括：第一非公共网络中的接入网设备确定第一非公共网络与公共网络互通。例如，第一非公共网络中的接入网设备确定第一非公共网络与公共网络互通可以通过以下方式实现：接入网设备根据运营商配置信息确定非公共网络与公共网络互通。
步骤702、第二终端根据广播信息，确定使用第一签约信息接入该第一非公共网络。其中，第一签约信息为第二终端在第一公共网络中的签约信息。
在一种可能的实现方式中，第一签约信息中携带的该第二终端的第一标识与第一公共网络相关。例如，该第二终端的第一标识中携带第一公共网络的信息，如网络标识PLMN ID。
可以理解的是，第一公共网络为与该第一非公共网络互通的一个或多个公共网络中的一个。
举例说明，第一公共网络可以为如图5b中的公共网络200。第一非公共网络可以为如图5b中的非公共网络100。接入管理网元可以为如图5b中的AMF网元1。
本申请实施例提供一种网络的接入方法，该方法中第二终端通过接收来自接入网设备广播的广播信息，这样便于第二终端根据广播信息中携带的第一指示信息确定第一非公共网络支持与公共网络之间的互通。然后第二终端可以确定使用第一签约信息接入该第一非公共网络。待后续第二终端需要接入该第一非公共网络时，便可以使用该第一签约信息请求在该第一非公共网络中注册，避免了第二终端在不知道公共网络和第一非公共网络之间互通的情况下，盲目向第一非公共网络发起注册请求，而导致的注册失败。
在一种可能的实施例中，本申请实施例提供的方法在步骤702之后还可以包括：第二终端使用第一签约信息接入该第一非公共网络。
在一种可能的实现方式中，第二终端使用第一签约信息接入该第一非公共网络可以通过以下方式实现：第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息，该第一消息用于表示在第一非公共网络中注册该第二终端。该第一消息中携带该第二终端的第一标识。
作为一种示例，该第一消息中可以携带注册指示，该注册指示用于表示在第一非公共网络中注册该第二终端。
在一种可能的实施例中，广播信息还包括与第一非公共网络互通的一个或多个公共网络的信息，第一公共网络属于该一个或多个公共网络。接入网设备通过广播一个或多个公共网络的信息，以便于第二终端确定该第二终端可以接入的一个或多个公共网络。
在一种可能的实现方式中，广播信息还可以包括手选接入指示，第二终端根据手选接入指示提示用户使用手动选择方式接入该第一非公共网络，防止第二终端自动选择到该第一非公共网络。
举例说明，如果该第一非公共网络属于A国家，则该一个或多个公共网络也属于A国家。
在一种可能的实现方式中，第一公共网络可以为该一个或多个公共网络中的任一个。即第二终端可以在一个或多个公共网络中任选一个公共网络作为第一公共网络。在另一种可能的实现方 式中，第一公共网络的网络选择优先级在一个或多个公共网络的网络选择优先级中为最高的。或者第一公共网络为该第二终端支持的公共网络。
应理解，第二终端中具有一个或多个公共网络中每个公共网络的网络选择优先级。
在一种可能的实现方式中，第二终端中具有与公共网络之间的签约信息。
图7所描述的实施例中涉及到的第一非公共网络可以为R17非公共网络。公共网络可以为R17公共网络。换言之，图7所描述的实施例中的第一非公共网络和公共网络之间采用漫游架构互通。
如图8所示，图8示出了本申请实施例提供的一种网络的接入方法的交互实施例，该方法包括：
步骤801、第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息，相应的，第一非公共网络中的接入管理网元接收来自第二终端的第一消息，该第一消息用于表示第二终端请求使用第一签约信息在第一非公共网络中注册。
作为一种示例，本申请实施例中的第二终端为支持第一版本网络的第二终端，所谓支持第一版本网络的第二终端是指：该第二终端中具有与第一版本的第一非公共网络之间的非公网签约信息，以及具有与第一版本的第一公共网络之间的公网签约信息。此时，步骤801中第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息中的“第一非公共网络”指第二版本的第一非公共网络。
当第二终端为支持第一版本网络的第二终端时，第一非公共网络中的接入管理网元可以为第二版本的第一非公共网络中的接入管理网元。此时，第一签约信息为第二终端在第一非公共网络中的签约信息，换言之，第一签约信息为第二终端在第一版本的第一非公共网络中的非公网签约信息。
作为另一种示例，本申请实施例中的第二终端为支持第二版本网络的第二终端，所谓支持第二版本网络的第二终端是指：该第二终端中具有与第二版本的第一公共网络之间的公网签约信息。此时，步骤801中第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息中的“第一非公共网络”指第一版本的第一非公共网络。
当第二终端为支持第二版本网络的第二终端时，第一非公共网络中的接入管理网元可以为第一版本的第一非公共网络中的接入管理网元。此时，第一签约信息为第二终端在第一公共网络中的签约信息。换言之，第一签约信息为第二终端与第二版本的第一公共网络之间的公网签约信息。
上述第一版本可以为R16版本，第二版本可以为R17版本。
在一种可能的实现方式中，第二版本的第一公共网络与第二版本的第一非公共网络采用漫游架构互通的情况下，该第一签约信息为第二终端在第一版本的第一非公共网络中的签约信息。此时，第一签约信息中携带的第二终端的第二标识与第一非公共网络相关，例如，第二终端的第二标识中包括第一非公共网络的标识。
在一种可能的实现方式中，第一版本的第一公共网络与第一版本的第一非公共网络采用N3IWF互通的情况下，该第一签约信息为第二终端在第二版本的第一公共网络中的签约信息。此时，第一签约信息中携带的第二终端的第三标识与第一公共网络相关。例如，第二终端的第三标识中包括第一公共网络的信息。例如，第一公共网络的信息用于识别第一公共网络。
应理解，本申请实施例中第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息可以理解为：第二终端向第一非公共网络中的接入管理网元发送第一消息，该第一消息中包括的第二终端的标识可以从第一签约信息中得到。
例如，如果第一非公共网络为第二版本的第一非公共网络，则第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送的第一消息中携带第二终端的第二标识。例如，如果第一非公共网络为第一版本的第一非公共网络，则第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送的第一消息中携带第二终端的第三标识。
步骤802、接入管理网元向第二终端发送第二消息，相应的，该第二终端接收来自接入管理网元的第二消息。
其中，第二消息用于拒绝第二终端在非公共网络中注册，该第二消息中包括第四指示信息，第四指示信息用于指示拒绝第二终端在非公共网络中进行注册的原因。
综上描述，图8所描述的实施例可以适用于：第二终端所签约的非公共网络或公共网络与第二终端进行注册的非公共网络的版本不同。即情况1、第二终端使用第二终端在第一版本的第一非公共网络中的私网签约信息请求在第二版本的第一非公共网络中注册时，第二版本的第一非公共网络中的接入管理网元拒绝该第二终端在第二版本的第一非公共网络中注册。情况2、第二终端使用第二终端在第二版本的第一公共网络中的公网签约信息请求在第一版本的第一非公共网络中注册时，第一版本的第一非公共网络中的接入管理网元拒绝该第二终端在第一版本的第一非公共网络中注册。
由于第一签约信息可以为第二终端在第一非公共网络中的签约信息，也可以为第二终端在第一公共网络中的签约信息，但是不同情况下，第二终端接收到第二消息之后的处理动作存在差异，下述将分别介绍：
示例1，第一签约信息为第二终端在第一非公共网络中的签约信息，是指第一签约信息为第二终端在第一版本的第一非公共网络中的签约信息。但是第二终端要注册的第一非公共网络为第二版本的第一非公共网络，第一公共网络为第二版本的第一公共网络。
本申请实施例提供一种网络的接入方法，该方法中第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息，该第一签约信息为第二终端在第一非公共网络中的签约信息或者该第一签约信息为第二终端在第一公共网络中的签约信息。之后第二终端接收来自接入管理网元的第二消息，这样便于后续第二终端根据第二消息确定第一非公共网络中的接入网管理网元拒绝第二终端在非公共网络中注册，以及根据第四指示信息确定接入管理网元拒绝第二终端在非公共网络中进行注册的原因。该方案可以解决第二终端使用第二终端在第一非公共网络中的签约信息在第一非公共网络中注册的问题，或者解决第二终端使用第二终端在第一公共网络中的签约信息在第一非公共网络中注册的问题。
如图9所示，图9示出了本申请实施例的另一种网络的接入方法，该方法包括：
步骤901、同步骤801，此处不再赘述。
步骤902、接入管理网元确定拒绝第二终端在该第一非公共网络中注册。
具体的，步骤902可以通过以下方式实现：接入管理网元根据配置信息或者第二终端在第一非公共网络中的签约信息确定拒绝第二终端在第一非公共网络中注册。
例如，配置信息指示该第一非公共网络不支持采用N3IWF模式与第一公共网络之间的互通，则接入管理网元确定拒绝第二终端在第一非公共网络中注册。
例如，第二终端在第一非公共网络中的签约信息指示第二终端不能再使用此签约信息接入该第一非公共网络，则接入管理网元确定拒绝第二终端在第一非公共网络中注册。
步骤903、同步骤802，此处不再赘述。
在一种可能的实施例中，如图9所示本申请实施例提供的方法在步骤903之后还可以包括步骤904，或者本申请实施例提供的方法在步骤904之后还可以包括步骤905和步骤906：
步骤904、接入管理网元向第二终端发送第四消息，相应的，第二终端接收来自接入管理网元的第四消息，该第四消息包括第二终端的网络候选列表。网络候选列表包括第一非公共网络的信息。
本申请实施例中网络候选列表包括第一非公共网络的信息时，表示第二终端可以在该第一公共网络中进行注册。该网络候选列表包括第一非公共网络的信息也可以替换为：网络候选列表中包括的第一公共网络对应的记录项处于激活状态。
应理解，第二终端的网络候选列表中包括第二终端可选择接入的一个或多个候选非公共网络。该第一非公共网络属于该一个或多个候选非公共网络。
可以理解的是，通过执行步骤904第二终端能够确定虽然第二终端使用第二终端在第一版本的第一非公共网络中的签约信息在第一非公共网络中注册被拒绝，但是第二终端能够在该第一非公共网络中注册。
步骤905、接入管理网元向第二终端发送第五消息，相应的，第二终端接收来自接入管理网元的第五消息，第五消息用于表示接受第二终端在第一非公共网络中注册。
例如，第五消息中包括接受指示，该接受指示用于表示接受第二终端在第一非公共网络中注册。
步骤906、第二终端根据第五消息，将第一非公共网络的信息添加到第二终端的网络候选列表中。
作为一种可替代的实现方式，本申请实施例中的步骤906也可以描述为：第二终端根据第五消息更新第二终端的网络禁选列表。其中，该更新后的网络禁选列表中包括第一非公共网络的信息。
关于第二终端更新第二终端的网络禁选列表的方式可以具体参考上述第一终端更新第一终端的网络禁止列表的过程，此处不再赘述。
可以理解的是，通过执行步骤905和步骤906第二终端能够确定虽然第二终端使用第二终端在第一版本的第一非公共网络中的签约信息在第一非公共网络中注册被拒绝，但是第二终端能够在第一非公共网络中注册。
在一种可能的实施例中，如图9所示本申请实施例提供的方法在第二终端确定可以在第一非公共网络中注册的情况下，还可以包括：
步骤907、第二终端根据第四指示信息，使用第二终端的第二签约信息在第一非公共网络中进行注册，第二签约信息为第二终端在第一公共网络中的签约信息。
该第二签约信息中包括第一公共网络的标识，该第二签约信息中包括第二终端的第五标识，该第五标识与第一公共网络的标识相关。
可以理解的是，当第一签约信息为第二终端在第一非公共网络中的签约信息时，第四指示信息还可以用于指示第二终端采用漫游架构在第一非公共网络中进行注册，换言之，第四指示信息还可以用于指示第二终端使用第二终端的第二签约信息在第一非公共网络中进行注册，本申请实施例对此不做限定。
本申请实施例提供一种网络的接入方法，该方法中第二终端使用第一签约信息向第一非公共网络中的接入管理网元发送第一消息，该第一签约信息为第二终端在第一非公共网络中的签约信 息。之后第二终端接收来自接入管理网元的第二消息，这样便于后续第二终端根据第二消息确定第一非公共网络中的接入网管理网元拒绝第二终端在非公共网络中注册，以及根据第四指示信息确定接入管理网元拒绝第二终端在非公共网络中进行注册的原因。后续如果该第二终端要继续在第一非公共网络注册，则第二终端可以根据该原因采用第二终端的第二签约信息在第一非公共网络中进行注册。该方案可以实现第二终端使用第二终端在第一非公共网络中的签约信息在第一非公共网络中注册被拒绝之后，使用第二签约信息在第一非公共网络中进行注册。
示例2，第一签约信息为第二终端在第一公共网络中的签约信息，是指第一签约信息为第二终端在第二版本的第一公共网络中的签约信息。但是第二终端将要注册的第一非公共网络为第一版本的第一非公共网络。与该第一版本的第一非公共网络互通的第一公共网络为第一版本的第一公共网络。
在这种情况下，第四指示信息用于指示第二终端为非法终端，换言之第四指示信息用于指示非公共网络不能识别该第二终端的身份。
如图10所示，图10示出了本申请实施例的另一种网络的接入方法，该方法包括：
步骤1001、同步骤801，此处不再赘述。
步骤1002、接入管理网元确定拒绝第二终端在该第一非公共网络中注册。
具体的，步骤1002可以通过以下方式实现：接入管理网元获取不到该第二终端的签约信息或者不能识别该第二终端的身份，即第二终端认证失败，则确定拒绝第二终端在第一非公共网络中注册。
步骤1003、同步骤802，此处不再赘述。
应理解，第二消息还用于指示该第二终端使用第三签约信息请求在第一非公共网络中进行注册。
在一种可能的实施例中，第二终端中还具有该第二终端在第一非公共网络中的第三签约信息的情况下，如图10所示，本申请实施例提供的方法在步骤1003之后还可以包括：
步骤1004、第二终端使用第三签约信息请求在第一非公共网络中进行注册。
应理解，该第三签约信息为第二终端与第一版本的第一非公共网络之间的签约信息。第三签约信息中包括第二终端的第四标识，该第四标识与第一非公共网络相关。例如，该第四标识中包括第一非公共网络的信息。如第一非公共网络的标识，关于第一非公共网络的标识的内容可以参考本申请实施例其他地方的描述，此处不再赘述。
作为一种可能的实现方式，本申请实施例中的步骤1004可以通过以下方式实现：第二终端向第一版本的非公共网络中的接入管理网元发送注册请求消息，该注册请求消息用于请求在该第一版本的非公共网络中注册该第二终端。该注册请求消息中包括该第二终端的第四标识。该第二终端的第四标识由第三签约信息确定，换言之，该第二终端的第四标识中包括第一非公共网络的信息。
作为一种可能的实现方式，当第二终端成功在该第一版本的第一非公共网络中注册之后，本申请实施例提供的方法还可以包括：第二终端使用该第二终端在第一公共网络中的签约信息请求在第一版本的第一公共网络中进行注册。
可以理解的是，在示例2中步骤1003中的第二消息中还可以包括用于指示第二终端使用第三签约信息请求在第一非公共网络中进行注册的指示信息。
本申请实施例提供一种网络的接入方法，该方法中第二终端使用第一签约信息向第一非公共 网络中的接入管理网元发送第一消息，该第一签约信息为第二终端在第一公共网络中的签约信息。之后第二终端接收来自接入管理网元的第二消息，这样便于后续第二终端根据第二消息确定第一非公共网络中的接入网管理网元拒绝第二终端在非公共网络中注册，以及根据第四指示信息确定接入管理网元拒绝第二终端在非公共网络中进行注册的原因为第二终端为非法终端。后续如果该第二终端要继续在第一非公共网络注册，则第二终端可以根据该原因采用第二终端的第三签约信息在第一非公共网络中进行注册。该方案可以实现第二终端使用第二终端在第一公共网络中的签约信息在第一非公共网络中注册被拒绝之后，使用第三签约信息在第一非公共网络中进行注册。
结合图5b所示的架构，如图11所示，图11以第一终端为非SNPN设备，第一非公共网络为R17版本的SNPN(下述简称：R17 SNPN，对应图5b中的非公共网络100)，接入管理网元为R17 SNPN中的SNPN AMF网元(对应图5b中的AMF网元1)，接入网设备为SNPN RAN，公共网络为R17版本的PLMN(下述简称：R17 PLMN，对应图5b中的公共网络200)，统一数据管理网元为图5b中的UDM网元为例，该方法包括：
步骤1101、非SNPN设备向SNPN AMF网元发送注册请求消息，相应的，SNPN AMF网元接收来自非SNPN设备的注册请求消息。该注册请求消息用于请求在R17 SNPN中注册非SNPN设备。
例如，注册请求消息中携带非SNPN设备的标识。例如，非SNPN设备的标识可以为SUPI或SUCI。
作为一种具体实现：步骤1101可以通过以下方式实现：非SNPN设备通过R17 SNPN中的SNPN RAN向SNPN AMF网元发送注册请求消息。此外，SNPN AMF网元还可以从SNPN RAN处接收R17 SNPN的标识，该R17 SNPN的标识用于识别R17 SNPN。其中，非SNPN设备的SUPI或SUCI中包含非SNPN设备的HPLMN ID。该HPLMN ID用于确定该非SNPN设备对应的归属地公共网络。
步骤1102、如果R17 SNPN与R17 PLMN之间不支持漫游互通，则SNPN AMF网元向非SNPN设备发送注册拒绝消息1，相应的，非SNPN设备接收来自SNPN AMF网元的注册拒绝消息1。
其中，注册拒绝消息1用于表示拒绝非SNPN设备在R17 SNPN中注册，该注册拒绝消息1中还可以携带表示拒绝非SNPN设备在R17 SNPN中注册的原因为：该非SNPN设备为非法终端(Illegal UE)。
步骤1103、如果R17 SNPN与R17 PLMN之间支持漫游互通，则SNPN AMF网元向R17 PLMN中的UDM网元发送签约获取请求消息，相应的，UDM网元接收来自SNPN AMF网元的签约获取请求消息。其中，签约获取请求消息用于请求非SNPN设备的签约数据。
例如，签约获取请求消息中携带R17 SNPN的标识以及非SNPN设备的标识。通过在签约获取请求消息中携带R17 SNPN的标识便于UDM网元确定该非SNPN设备要接入的非公共网络。
如图11所示，步骤1103可以通过以下方式实现：SNPN AMF网元向R17 SNPN中的V-SEPP发送签约获取请求消息。之后V-SEPP向R17 PLMN中的H-SEPP发送获取到的签约获取请求消息，以由H-SEPP向UDM网元转发该签约获取请求消息。
步骤1104、UDM网元向SNPN AMF网元发送签约获取响应消息，相应的，SNPN AMF网元接收来自UDM网元的签约获取响应消息，该签约获取响应消息用于SNPN AMF网元确定拒绝非SNPN设备在R17 SNPN中注册。
如图11所示，步骤1104可以通过以下方式实现：UDM网元向R17 PLMN中的H-SEPP发送 签约获取响应消息。之后H-SEPP向R17 SNPN中的V-SEPP发送获取到的签约获取响应消息，以由V-SEPP向R17 SNPN中的SNPN AMF网元发送该签约获取响应消息。
例如，一方面，签约获取响应消息中携带非SNPN设备的签约数据，该签约数据中包括第二指示信息，该第二指示信息用于指示非SNPN设备只能通过公共网络接入。或者，第二指示信息用于指示非SNPN设备不能通过非公共网络接入。例如，第二指示信息包括该非SNPN设备支持的网络列表。其中，该非SNPN设备支持的网络列表中不包括该R17 SNPN的信息。或者该非SNPN设备支持的网络列表中该R17 SNPN对应的记录项用于表示该R17 SNPN是被禁止接入的。
另一方面，签约获取响应消息中包括第三指示信息，该第三指示信息用于指示未成功获取该非SNPN设备的签约数据。
再一方面，签约获取响应消息中包括原因值，原因值用于表示不允许该非SNPN设备在R17SNPN中接入。
又一方面，签约获取响应消息中未包括非SNPN设备的签约数据。
步骤1105、SNPN AMF网元根据签约获取响应消息确定拒绝非SNPN设备在R17 SNPN中注册。
步骤1106、SNPN AMF网元向非SNPN设备发送注册拒绝消息2，相应的，非SNPN设备接收来自SNPN AMF网元的注册拒绝消息2。该注册拒绝消息2用于表示拒绝非SNPN设备在R17 SNPN中注册。该注册拒绝消息2中还可以携带拒绝非SNPN设备在R17 SNPN中注册的原因。例如，拒绝非SNPN设备在R17 SNPN中注册的原因为不允许该非SNPN设备接入该R17 SNPN。
步骤1107、非SNPN设备将R17 SNPN的信息加入该非SNPN设备的网络禁选列表。
应理解，步骤1107还可以通过以下方式实现：非SNPN设备更新该非SNPN设备的网络禁选列表。其中，更新后的非SNPN设备的网络禁选列表中包括R17 SNPN的信息。R17 SNPN的信息用于识别R17 SNPN。例如，R17 SNPN的信息可以为R17 SNPN的标识。
应理解，网络禁选列表中包括该非SNPN设备禁止接入的一个或多个网络，该一个或多个网络包括上述R17 SNPN。
在一种可能的实施例中，本申请实施例提供的方法在步骤1107之后还可以包括：
步骤1108、非SNPN设备根据网络禁选列表执行网络选择，以选择除该网络禁选列表中的网络进行注册。
需要说明的是，在图11所示的实施例中，步骤1101和步骤1102可以形成一个单独的实施例，用以解决在R17 SNPN与R17 PLMN之间不支持漫游架构互通的情况下，非SNPN设备接入R17 SNPN的问题。步骤1101、步骤1103～步骤1108可以形成一个单独的实施例，用以解决在R17 SNPN与R17 PLMN之间支持漫游架构互通的情况下，非SNPN设备接入R17 SNPN的问题。
需要说明的是，在图11所示的实施例中的注册请求消息可以对应上述图6所示的实施例中的第一消息。签约获取响应消息可以对应上述图6所示的实施例中的第三消息。注册拒绝消息2可以对应上述图6所示的实施例中的第二消息。签约获取请求消息可以对应上述图6所示的实施例中的查询消息。拒绝非SNPN设备在R17 SNPN中注册的原因可以对应上述图6所示的实施例中的第一指示信息。
结合图5b，如图12所示，图12示出了本申请的另一种网络的接入方法的具体实施例，该实施例以第一非公共网络为R17 SNPN，接入网设备为SNPN RAN，第二终端为SNPN设备为例，该方法包括：

可以理解的是，该SNPN设备位于R17 SNPN的覆盖范围内，且该SNPN设备能够接收到来自SNPN RAN的广播信息。
步骤1202、该SNPN设备根据广播信息中的互通指示，确定使用该SNPN设备与R17 PLMN之间的签约信息接入该R17 SNPN与R17 PLMN。
在一种可能的实现方式中，如果该广播信息中还包括与R17 SNPN互通的一个或多个R17 PLMN的标识，则步骤1202可以通过以下方式实现：该SNPN设备根据广播信息中的互通指示，确定使用该SNPN设备与目标R17 PLMN之间的目标签约信息接入该R17 SNPN与R17 PLMN。其中，目标R17 PLMN属于该一个或多个R17 PLMN。
