相关申请的交叉引用
本申请主张在2018年6月22日在中国提交的中国专利申请号No.201810655001.8的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信技术领域，尤其涉及一种处理方法、终端及网元
背景技术
相关技术中，许多垂直行业都有通信的需求，比如铁路调度、自动化控制等。第五代移动通信技术(5th-Generation，5G)通信网络可以为垂直行业提供一种局域网(Local Area Network，LAN)类型的私有通信服务，满足垂直行业的通信需求。其中，LAN类型服务可以是指在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)网络系统上提供的IP类型或非IP类型的私有通信服务。
私有虚拟网络(Private Virtual Network，PVN)可以是一个支持LAN类型服务的私有虚拟网络。PVN和LAN的概念可能会混用，可以泛指私有通信网络或私有通信服务。
私有通信网络可以分为类型A网络和类型B网络。类型A网络可以是一个不用于公众的通信网络(比如3GPP网络)，但是该网络可以与运营商网络进行服务连续性或漫游。类型B网络可以是一个不与运营商网络比如公共陆地移动网络(Public Land Mobile Network，PLMN)交互的隔离的通信网络(比如3GPP网络)。
私有通信网络作为垂直行业的私有通信网络传输网络，可以支持私有通信网络内的终端私有通信网络中业务或实现私有通信网络的终端之间的通信。
当通过运营商网络为垂直业务提供私有通信网络时，垂直业务的终端可以接入私有通信网络进行相互通信或者访问垂直业务的服务器。垂直行业的终端还可能同时访问运营商的公众通信网络，进行公众通信业务。但相关技 术中，对于终端如何分别接入私有通信网络和公众通信网络尚不明确。

具体实施方式
首先指出，本公开实施例可以解决的问题如下：
(一)标识的问题
运营商的网络通过公共陆地移动网络ID(Public Land Mobile Network ID，PLMN ID)标识。PLMN ID个数是有限的。一个运营商网络上可以具有支持多个垂直业务的多个私有通信网络(PVN)，一个垂直业务可以跨多个运营商网络。所以不能将PLMN ID作为私有通信网络的标识。一个垂直业务的私有通信网络可以包含多个网络切片，不能将网络切片相关标识作为私有通信网络的标识。所以，如何标识一个垂直业务在运营商中的私有通信网络还不清楚。
(二)上层应用的网络类型许可
当通过运营商网络为垂直业务提供私有通信网络时，垂直业务的终端可以接入私有通信网络进行相互通信或者访问垂直业务的服务器。垂直行业的终端还可能同时访问运营商的公众通信网络，进行公众通信业务。相关技术中，终端上没有信息能够限制哪些上层应用接入私有通信网络，哪些应用接入公众通信网络。
其中，对于类型B网络的终端，只能接入私有通信网络；对于类型A网络的终端，可以接入私有通信网络和公众通信网络。
(三)移动和漫游范围许可
私有通信网络的服务范围可能是有限区域，而不是全网覆盖。对一个垂直业务的终端，还不清楚哪些网络区域支持该垂直业务的私有通信网络，即在哪可以接入私有通信网络。对运营商的网络，可能划分了多个私有虚拟网络支持私有通信服务。如何为终端选择私有通信网络中的网元还不清楚。
其中，对于类型B网络，只具有私有通信网络的移动范围；对于类型A网络，具有私有通信网络的移动范围、漫游的移动范围、是否允许漫游到公众通信网络。
另外，对于类型A网络，需要在进行私有通信网络注册时告知是否允许接入公众通信网络，在进行公众通信网络注册时告知是否允许接入私有通信网络。
(四)总体架构
如果当前小区同时支持私有通信网络和公众通信网络，优先注册到哪种通信网络还不清楚，无线接入网(Radio Access Network，RAN)网元如何选择接入移动管理功能(Access Management Function，AMF)还不清楚。
UE向RAN发送无线资源控制(Radio Resource Control，RRC)请求，用于请求指示私有通信网络ID。网络还需要结合RAN是否支持私有通信网络ID来决定注册的类型。
本公开实施例提出以下几种总体架构，其中，总体架构示意图请一并参阅图1a至图1c。需要说明的是，图1a至图1c中所示的切片表示网络切片。
总体架构一：如图1a所示，无线接入网是各个私有通信网络和公众通信网络共享的；AMF和切片是各个私有通信网络和公众通信网络独有的，也就是说，各私有通信网络和公众通信网络都具有专享的AMF。
总体架构二：如图1b所示，无线接入网和AMF是各个私有通信网络和公众通信网络共享的；切片是各个私有通信网络和公众通信网络独有的。
总体架构三：如图1c所示，无线接入网、AMF和切片都是各个私有通信网络和公众通信网络。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。

根据所述第一信息，选择第一网络，所述第一网络为支持私有通信服务 的网络；
向所述第一网络发送所述终端支持的私有通信服务的能力和所述终端请求接入的私有通信网络的信息中的至少一项。
一种实施方式下，终端向第一网络发起注册请求，在注册请求中包含第一信息。如图1b所示的总体架构，当AMF是私有通信网络和公众通信网络共有的设备时，AMF可以为终端选择私有通信网络。
另一种实施方式下，终端向第一网络的无线接入网发起RRC消息，在RRC消息中包含第一信息。图1a所示的总体架构，当私有通信网络的AMF和公众通信网络的AMF是独立设备，且终端请求接入私有通信网络时，无线接入网节点可以为终端选择私有通信网络下的AMF。
需要说明的是，本实施例中介绍的多种可选的实施方式，彼此可以相互结合实现，也可以单独实现，对此本公开实施例不作限定。
本实施例的处理方法至少具有以下有益效果：
支持私有通信网络的运营商网络信息。不难理解，一个垂直业务的私有通信网络可能会部署在多个运营商的网络中。对私有通信网络P的用户V，私有通信网络部署在运营商A和运营商B。用户V是运营商A的发卡用户，漫游的情况下，用户V可以支持接入运营商B的私有通信网络。所以支持私有通信网络的运营商网络信息也可以成为私有通信网络相关的漫游网络信息。终端可能同时支持接入私有通信网络和接入公众通信网络，所以私有通信网络相关的漫游网络信息和公众通信网络的漫游网络信息可以是不同的。
不难理解，终端可能同时支持接入私有通信网络和接入公众通信网络。私有通信网络可能和公众通信网络共享无线接入网。一种实施方式，根据私有通信网络区域范围信息，终端知道哪些区域提供私有通信网络。当终端移动到这些支持私有通信网络的区域时，就可以发起私有通信服务。另一种实施方式，支持私有通信网络的小区广播的私有通信网络的标识，终端根据从第一信息中获取的私有通信网络的标识进行对比，也可以知道小区是否支持配置的私有通信网络，是否可以发起私有通信服务。
对于允许接入私有通信网络(或者称为允许采用私有通信服务)的应用信息、禁止接入私有通信网络(或者称为禁止采用私有通信服务)的应用信 息。不难理解，终端可能同时支持接入私有通信网络和公众通信网络。终端上有些应用只允许在私有通信网络下运行。终端上有些应用只允许在公众通信网络下运行。通过配置允许接入私有通信网络的应用信息，可以帮助终端在应用产生数据时，是触发接入私有通信网络还是触发接入公众通信网络。另一种实施方式中，通过配置应用的接入网络的类型也可以达到同样的目的。
参见图3，图3是本公开实施例提供的处理方法的流程图之二。本实施例的处理方法应用于第一网元，所述第一网元可以包含RAN网元，用于帮助终端决定接入网络的操作。如图3所示，本实施例的处理方法包括以下步骤：

其中，所述第一目标端可以包括终端、RAN网元和CN网元中的至少一项。RAN网元可以包括至少以下之一、gNB、eNB。
应理解的是，具体实现时，第一网元可以通过广播的方式向第一目标端发送上述信息，也可以通过其他下行消息，如RRC消息发送上述信息，具体可根据实际需要决定，本公开实施例对此不作限定。
需要说明的是，私有通信网络的重定向信息可以用于指示支持私有通信网络的网络。这样，即使当前网络不支持私有通信网络，但当前网络可以广播私有通信网络的重定向信息，从而终端在获取到私有通信网络的重定向信息后，可以快速找到支持私有通信网络的网络，从而可以缩小终端查找支持私有通信网络的网络范围，进而提高终端查找支持私有通信网络的网络的效率。
进一步地，所述支持的私有通信网络的信息，可以包括至少以下之一：
支持的私有通信网络的标识、支持的私有通信网络的频点、支持的私有通信网络的重定向的频点信息。
