本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，图1是本发明实施例方案涉及的硬件运行环境的终端结构示意图。
本发明实施例提供一种终端，又叫NPN网络的远程签约装置，终端可以是由单独的NPN网络的远程签约装置构成，也可以是由其他装置与NPN网络的远程签约装置组合形成，本实施例中的终端可以以各种形式来实施。例如可以是PC，也可以是智能手机、平板电脑、电子书阅读器、导航装置、可穿戴设备、分布式***和网络侧设备（或网络侧设备集群）等。
如图1所示，该终端可以包括：处理器1001，例如CPU，通信总线1002，用户接口1003，网络接口1004，存储器1005。其中，通信总线1002用于实现这些组件之间的连接通信。用户接口1003可以包括显示屏（Display）、输入单元比如键盘（Keyboard），可选的用户接口1003还可以包括标准的有线接口、无线接口。网络接口1004可选的可以包括标准的有线接口、无线接口（如WI-FI接口）。存储器1005可以是高速RAM存储器，也可以是稳定的存储器（non-volatile memory），例如磁盘存储器。存储器1005可选的还可以是独立于前述处理器1001的存储装置。
本领域技术人员可以理解，图1中示出的终端结构并不构成对终端的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图1所示，作为一种计算机存储介质的存储器1005中可以包括操作***、网络通信模块、用户接口模块以及NPN网络的远程签约程序。
在图1所示的终端中，网络接口1004主要用于连接后台服务器，与后台服务器进行数据通信；用户接口1003主要用于连接客户端（用户端），与客户端进行数据通信；而处理器1001可以用于调用存储器1005中存储的NPN网络的远程签约程序，并执行下述NPN网络的远程签约方法中的操作，在此不作赘述。
本发明终端的具体实施例与下述NPN网络的远程签约方法各实施例基本相同，在此不作赘述。
本发明第一实施例提供一种NPN网络的远程签约方法，所述NPN网络的远程签约方法包括：
步骤S01，UE获取核心网分配的NPN网络的签约信息，其中所述签约信息包括UE在PLMN中的标识信息。
本实施例应用于5G（5th Generation Mobile Networks，第五代移动通信技术）通讯，由UE（User Equipment，用户终端）执行，后续简称终端或者UE。
相对应地，当方案应用于网络侧，即核心网时，UE进行NPN网络签约的过程可以包括：
步骤S02，向UE分配NPN网络的签约信息，所述NPN网络由公共陆地移动网络PLMN部署，其中所述签约信息包括终端在PLMN中的标识信息。
上述NPN（Non-Public Network，非公共网络）网络的设备实体可以由PLMN（Public Land Mobile Network，公共陆地移动网络）部署管理，这种NPN网络既可以是SNPN（Standalone NPN），即独立的非公共网络，也可以是CAG（Cell Access Group，闭合接入组）网络。在这种情况下的UE有PLMN中的签约信息，即UE在PLMN中的标识信息，例如SUPI（SUbscription Permanent Identifier）信息或者GUTI信息，其中SUPI信息为终端在5G中的真实身份信息，GUTI信息为临时身份信息，可以将该标识信息作为NPN网络签约用的签约授权信息。在核心网完成该UE对应NPN网络的签约授权时，可以分配NPN的签约信息至UE，其中的签约信息就包括有该UE设备在PLMN的标识信息。当然，核心网也可以仅用于签约信息的分配，不起是否允许授权验证的作用，即直接向终端分配NPN网络的签约信息。需要说明的是，对于终端设备其可以主动发起NPN网络的签约请求，也可以不发起请求，直接由核心网向其自发分配。
在本实施例中通过UE获取核心网分配的非公共网络NPN网络的签约信息，其中所述签约信息包括UE在公共陆地移动网络PLMN中的标识信息。其中借助终端设备在进行PLMN签约时的表示签约信息的标识信息作为NPN网络的签约信息，使NPN网络的核心网能够远程实现终端的接入签约授权，也不需要额外的SIM卡占据终端硬件空间，帮助解决了目前终端设备难以实现非公共网络的授权签约的技术问题。
需要说明的是，当UE以主动发起请求的方式向核心网申请签约信息，且核心网不做允许授权验证，NPN网络的授权签约过程可以是：UE发起NPN网络签约请求至核心网，以供所述核心网根据所述NPN网络签约请求分配签约信息；然后再由UE进行该签约信息的获取操作，最终完成授权签约。
这其中对于请求中包含的内容不同还存在以下细化方案：第一种是如果签约请求中携带有终端请求签约的NPN网络标识，即指定需要请求某个或某些NPN网络的授权签约，则核心网会分配NPN网络标识对应NPN网络的签约信息给到终端。第二种是终端在签约请求中标识未指定、指定所有或者直接不包括请求签约的NPN网络标识时，可以由核心网自主分配所有允许该UE签约的所有NPN网络的签约信息给到终端设备，由此一次性完成所有可行的非公网络签约。
进一步地，参见图2，基于本发明NPN网络的远程签约方法的第一实施例提出本发明的第二实施例，其中当由UE向核心网发起授权进而触发核心网对UE进行NPN网络的授权签约时，所述方法可以包括步骤：
步骤S10，UE发起NPN网络签约请求至核心网，以供所述核心网根据该签约请求确定是否允许所述UE获得NPN网络的授权签约；
步骤S20，所述UE获取核心网在确认允许授权签约后所反馈的所述NPN网络的签约信息，其中所述签约信息包括UE在PLMN中的标识信息。
终端可以通过多种途径将NPN网络签约请求发送给核心网，由核心网中具有接入授权功能的实体设备，例如AMF（Core Access and Mobility Management Function，接入管理功能）实体或UDM（Unified Data Management，统一数据管理）实体，根据UE发送的签约请求确定是否能够允许获得NPN网络的授权签约。
在核心网确定UE允许获得授权时，可以由具有接入授权功能的实体设备分配签约信息，最终反馈至UE处。其中所述签约信息除包括标识信息外，还可以包括获得授权的NPN网络的范围信息，例如包含的小区信息、注册区信息等，也可以包括签约的业务信息，以及终端在NPN网络中的标识信息，以方便在获得签约授权后，终端能够直接登入该NPN网络实现数据信息的传输。
而以网络侧的角度，当接收到请求时按照签约请求进行授权签约的过程可以包括：获取所述UE发起的NPN网络签约请求，并根据该签约请求确定是否允许所述UE获得NPN网络的授权签约；当确认允许所述授权签约时，向UE分配NPN网络的签约信息。其详细实现过程与前述实施例对应，在此不作赘述。
可选地，核心网对于NPN网络的授权可以按照终端的需求考虑，例如若终端的签约请求中包括有需要申请签约的NPN网络的标识，则核心网依据请求为终端确认是否允许NPN网络标识对应NPN网络的授权签约；相反，如果不包括NPN网络标识，则核心网会确认终端满足哪些NPN网络的授权签约要求，一旦完成授权签约，将完成允许授权的所有NPN网络与该UE的授权签约。
对应上述请求的内容不同，终端侧的实现过程如下：
步骤S11，所述UE发起NPN网络签约请求至核心网，以供所述核心网确定该签约请求中是否包括所述UE请求的NPN网络标识以及根据该签约请求确定是否允许所述UE获得NPN网络的授权签约；
步骤S21，所述UE获取核心网在确认该签约请求中包括所述NPN网络标识且允许所述授权签约后所反馈的所述NPN网络标识对应的NPN网络的签约信息；
步骤S22，所述UE获取核心网在确认该签约请求中不包括所述NPN网络标识且允许所述授权签约后所反馈的对应所有NPN网络的签约信息。
网络侧时，前述步骤中根据该签约请求确定是否允许所述UE获得NPN网络的授权签约的步骤可以分成两种情况：其一是当该签约请求中包括所述UE请求的NPN网络标识时，根据该签约请求确定是否允许所述UE获得所述NPN网络标识对应的NPN网络的授权签约；其二当该签约请求中不包括所述UE请求的NPN网络标识时，根据该签约请求确定是否允许所述UE获得对应所有NPN网络的授权签约。
通过终端发起NPN网络签约请求中是否包含有请求签约的NPN网络标识，对应有单独针对性地或者全面覆盖的网络签约授权方式，灵活多样。此外，覆盖性的授权方式，也防止UE需要多次进行授权签约，能单次完成所有授权签约操作，节省了不必要的授权签约流程。
进一步地，基于本发明NPN网络的远程签约方法第二实施例提出一种NPN网络的远程签约方法的第四实施例，在该实施例中，所述步骤S10包括：
步骤S12，所述UE发起NPN网络签约请求至核心网的AMF实体，其中签约请求包括其在PLMN中的标识信息，以供所述核心网通过所述AMF实体获取签约请求后根据该签约请求中的所述标识信息确定是否允许所述UE获得NPN网络的授权签约。
在本实施例中，是将AMF实体作为核心网接收标识信息的媒介，其可以直接接收由UE发送的包括标识信息的签约请求，例如接收的方式可以通过NAS（Non Access Stratum，非接入层）消息接收，也可以经由NPN网络的基站中转。需要说明的是，对于AMF实体在本实施例中可以起到接入身份验证的作用，可以验证申请签约的终端的合法性，也起到了终端与核心网之间数据传输的功能。
可选地，当通过NPN网络的基站中转再通过AMF实体设备接收时，其实现过程可以包括如下步骤：
步骤S121，所述UE发起NPN网络签约请求至NPN网络的基站，其中签约请求包括标识信息以及请求签约的NPN网络标识，以供所述基站将该签约请求发送给所述AMF实体，使所述核心网通过所述AMF实体获取该签约请求后根据该签约请求中的所述标识信息确定是否允许所述UE获得所述NPN网络标识对应的NPN网络的授权签约。
其中UE可以通过RRC（Radio Resource Control，无线资源控制）消息发送签约请求给NPN网络的基站，以供所述基站将签约请求发送给所述AMF实体，使所述核心网通过所述AMF实体获取请求。
请参看图3的1.1、2至3的传输过程，终端UE在上行的RRC消息以请求的形式携带需要请求签约信息的NPN网络标识信息，例如在该图示中的NPN网络为PNI-NPN（Public network integrated NPN），即携带的NPN网络标识为PNI-NPN ID，同时携带有UE在PLMN中的用作签约信息的标识信息，例如SUPI信息或GUTI信息。基站接收到终端的消息后，根据终端在消息中提供的信息选择核心网，并且将终端的请求提供给选择的核心网中的AMF实体，在图3中是通过NG-AP消息发送。
当直接通过AMF实体进行信息获取时，其实现过程可以包括两种方式，其一是由终端基于请求的方式提供标识信息进行NPN网络的授权签约，其二是不基于终端请求的方式，直接以消息携带的方式进行传输。其中需要额外说明的是，针对其二的实现方式可以参考第一实施例，实质对于核心网或者终端来说，当不由终端发送签约请求，核心网也可以直接分配签约信息给终端，可以是在整个方案之前由终端在发送消息时携带标识信息给到核心网，其可选地实现方式可以参照下述“其二”的实现方式。
其一的实现过程可以包括以下步骤：
步骤S122，所述UE发起NPN网络签约请求至AMF实体，其中签约请求包括标识信息以及请求签约的NPN网络标识，以供核心网通过AMF实体接收该签约请求并根据该签约请求中的所述标识信息确定是否允许所述UE获得所述NPN网络标识对应的NPN网络的授权签约。
其中所述UE可以将生成的请求通过NAS（Non-Access Stratum，非接入层）消息发送给核心网的AMF实体，以供核心网通过AMF实体接收所述NAS消息，并从所述NAS消息中获得的所述标识信息。
请继续参看图3，其中的1.2过程为终端通过NAS消息传递签约请求至核心网的过程，终端将生成的请求消息通过NAS消息发送给核心网的AMF实体，其中请求携带有需要请求的签约信息的NPN网络标识，此处仍以PNI-NPN网络为例，即NPN网络标识为PNI-NPN ID，同时携带终端在PLMN中的标识信息。可选地，此处的NAS消息可以是注册请求消息。
还需要说明的是，其中对于签约请求中是否包括NPN网络标识是可供选择的，即对应核心网在确认允许授权签约时反馈的是特定的目标NPN网络的签约信息还是所有可允许的，若不包括NPN网络标识可能之前终端也没有进行过NPN网络的签约申请，可以使该终端一次性获取所有允许加入的NPN网络的签约信息，即与所有可以进行签约的NPN网络完成远程签约，签约覆盖范围广。具体在前述方案中也已有过陈述，在此不过多赘述。
不论是通过基站中转还是直接发送给核心网的AMF实体，基于请求的方式所进行的NPN网络远程签约针对性强，帮助解决了目前终端设备难以实现非公共网络的授权签约的技术问题。
其二不基于终端请求的方式，直接以消息携带的方式进行传输至核心网的过程可以包括：所述UE发送携带所述标识信息的NAS消息至所述核心网的AMF实体，以供所述核心网通过所述AMF实体从所述NAS消息中获取所述标识信息并根据所述标识信息确定是否允许所述UE获得对应的所有NPN网络的授权签约。在不基于请求的方式进行PLMN中标识信息的发送时，可以不携带NPN网络标识，此时的NAS消息参照前述实现方式，也可以是注册请求消息。
还需要说明的是，前述仅说明了核心网对于终端申请签约所需信息的接收过程，其完成授权验证的实体设备则可以按需进行选择，在可选的其他实施例中，可以是单独由例如AMF实体或者UDM实体的签约设备管理实体进行授权验证，可以理解的是这其中UDM实体具有基于用户数据的接入授权功能，也可以是由AMF实体和UDM实体共同允许授权验证后反馈签约信息给终端。
以AMF实体和UDM实体共同完成允许授权验证的过程可以包括：AMF实体验证终端是否授权获取其所请求的NPN网络的签约信息，在AMF实体完成验证后，可以将终端请求签约所使用的信息发送给签约设备管理实体，例如UDM实体，由UDM实体验证终端是否允许获得NPN网络的签约信息，如果允许，则分配给终端相应的NPN网络的签约信息。可选地，UDM实体可以验证终端是否有管理NPN网络的PLMN的标识信息，若是，则可以允许获得授权。
即基于终端侧可以发现其实现过程包括：所述UE发起包括标识信息的NPN网络签约请求至核心网的AMF实体，以供核心网中的AMF实体根据所述标识信息验证所述UE允许获得所述NPN网络的授权签约后将所述标识信息发送给UDM实体以触发UDM实体根据所述标识信息确定是否允许所述UE获得NPN网络的授权签约。
本方案通过多种可选实体设备进行授权验证，能够帮助多终端设备快速进行NPN网络的远程授权，快捷方便。
进一步地，基于NPN网络的远程签约方法的第二实施例提出本发明NPN网络的远程签约方法的第五实施例，在本实施例中，所述步骤S10可以包括：
步骤S26，所述UE通过应用层发起包括申请信息的NPN网络签约请求至核心网的AF（Application Function，应用功能）实体，其中所述申请信息中至少包括其在PLMN中的标识信息，以供所述AF实体将所述申请信息发送给所述核心网的UDM实体使所述UDM实体根据所述标识信息确定是否允许所述UE获得NPN网络的授权签约。
本实施例与前述实施例通过核心网的AMF实体接收申请所需的签约信息的区别在于，是通过应用层发起的NPN网络签约申请，由核心网的AF层接收，其中包括申请信息，该申请信息至少包括标识信息，AF实体接收终端申请签约所需的信息后将其发送给UDM实体进行授权验证。还需要说明的是，采用应用层发送签约申请时，申请所需的信息还可以包括终端的相对外部标识，即通用公共用户标识符GPSI标识、PLMN信息、申请签约信息的NPN网络的信息或者UDM实体可以授权的所有NPN网络的信息等。
进一步地，基于本发明NPN网络的远程签约方法的第一实施例至第五实施例中任一实施例提出本发明NPN网络的远程签约方法的第六实施例，在本实施例中，所述步骤S20包括：
步骤S21，所述UE获取核心网经核心网的AMF实体、AF实体或者核心网的AMF实体以及NPN网络的基站所分配的所述NPN网络的签约信息。
在本实施例中，UE获取核心网反馈的签约信息的途径至少包括三种，分别是直接通过AMF实体反馈签约信息给终端，直接通过AF实体反馈签约信息给终端以及顺序经过AMF实体和NPN网络的基站反馈签约信息给终端。
以签约信息由UDM实体为例进行举例说明，当采用顺序经过AMF实体和NPN网络的基站反馈签约信息时其过程可以包括：AMF实体接收UDM实体分配的签约信息，并将分配的签约信息通过NG-AP消息发送给基站，基站通过RRC消息发送签约信息给终端。当单独采用AMF分配时，则由AMF实体直接通过NAS消息将分配的签约信息传递给终端，以完成终端相对NPN网络的远程签约。当单独采用AF实体进行消息分配时，分为两种情况，第一种是核心网途径基站和AMF实体或单独通过AMF实体获得终端的申请签约所需的信息，UDM实体审核授权后经AF反馈，此时终端需要额外提供AF信息，例如AF标识信息，DNN信息，用于使UDM能够提供签约信息给对应的AF，此外，DNN信息还能够区分对应的运营商；第二种是核心网直接通过AF层接收终端申请签约所需的信息，在UDM实体允许授权签约后，再由AF实体反馈签约信息，整个远程签约的过程传播仅依靠AF实体，对于终端来说就还需要额外指示PLMN信息，该PLMN信息与前述采用AF层进行发送时PLMN信息的一致，均为PLMN的ID信息，用于区分多个PLMN使用同一UDM实体时，确认具体PLMN的归属。由AF获取到终端申请NPN网络的标识信息后，将标识信息连同PLMN信息，申请签约的NPN信息或者能够签约的所有NPN网络的信息一同发送给UDM实体，UDM实体允许终端签约后，将分配的签约信息提供给相应的AF实体，以使AF实体将获得的签约信息提供给终端。
本实施例提供了多种可供选择的签约信息反馈方式，使多终端设备请求NPN网络签约时不会造成传输拥堵，最终完成了终端设备基于PLMN的NPN网络远程签约过程。
还需要说明的是，前述涉及AF实体和UDM实体之间的所有传输所采用的接口均可以通过间接接口传输，例如通过NEF（Network Element Function,网元功能）实体转接。此外本申请中NPN的远程签约方法还可以适用于LTE***，需要将AMF实体更换为MME实体（Mobility Management Entity，移动性管理实体），将UDM实体更换为HSS（Home Subscriber Server，归属用户服务器）实体，具体实现过程在此不再赘述。
