具体实施方式
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，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本公开及其应用或使用的任何限制。基于本公开中的实施例，本领域普通技术人员在没有做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。
针对目前标准中没有提供5G独立组网场景中如何为终端提供非公共网络服务的具体方案的问题，提出本方案。
本公开中在终端侧添加新的标识。例如，添加独立组网下非公共网络的终端注册并通过授权的一个或多个SNPN对应的NID(Network identifier，网络标识)。上述标识可以在终端签约注册时确定，核心网和终端可以各保留一份。在终端接入和切换过程中，基站可以通过核心网获取上述标识，后续将进行具体描述。
在网络侧添加新的标识，例如，添加基站支持的一个或多个SNPN对应的NID，通过NID和相应的PLMN标识可以唯一确定一个SNPN网络。
下面结合图1进行描述本公开通信方法的一些实施例。
图1为本公开通信方法一些实施例的流程图。如图1所示，该实施例的方法包括：步骤S102～S112。
在步骤S102中，第一基站发送广播消息，相应的，终端监听第一基站发送的广播消息。
广播消息包括：第一基站支持的一个或多个SNPN对应的NID和PLMN标识。广播消息包括：第一基站支持的NID，第一基站支持的NID可以有一个或多个，如果有多个可以形成NID列表，可以在SIB(系统消息块)，例如，SIB1中包含第一基站支持的NID。广播消息还可以包括现有标准中已经确定的各种信息，例如，PLMN(Public Land Mobile Network，公共陆地移动网络)标识等。
在步骤S104中，终端根据接收到的广播消息，确定第一基站是否支持终端签约的一个或多个SNPN；
在一些实施例中，终端接收到广播消息后解析广播消息获取第一基站支持的SNPN对应的NID和PLMN标识。终端根据自身签约的SNPN对应的NID和PLMN标识，以及第一基站支持的SNPN对应的NID和PLMN标识的比对结果，确定第一 基站是否支持终端签约的SNPN。如果第一基站支持的SNPN对应的NID和PLMN标识包括终端签约的SNPN对应的NID和PLMN标识，则第一基站支持终端签约的SNPN，否则，第一基站不支持终端签约的SNPN。
在步骤S106中，在第一基站支持终端签约的SNPN且终端选择第一基站的情况下，终端向第一基站发送连接请求，相应的，第一基站接收终端发送的连接请求。
支持终端签约的SNPN的基站除了第一基站可能还会有其他一个或多个基站，上述过程可以作为对现有小区选择或小区重选的流程的改进。即在终端当前处于小区选择场景的情况下，采用小区选择流程中的规则选取第一基站或其他基站，或者，在终端当前处于小区重选场景的情况下，采用小区重选流程中的规则选取第一基站或其他基站。
针对现有小区选择和小区重选的信令流程做出以下改进，未改进的部分可以参考现有标准。终端周期性的监听广播信息中的NID和PLMN，通过签约的SNPN对应的NID和PLMN标识，判断自己是否属于广播信息中的NID和PLMN对应小区的SNPN签约终端，如果属于，则根据小区选择或小区重选的规则选取广播信息中的NID和PLMN对应的小区进行接入。
终端向第一基站发送连接请求例如为RRC Setup Request(无线资源控制建立请求)，该信息可以参考现有技术。
第一基站根据连接请求，可以将终端接入相应的SNPN，具体如下。
在步骤S108中，第一基站根据连接请求，与终端建立RRC连接。
在步骤S110中，终端向第一基站发送RRC建立完成消息，相应的，第一基站接收终端发送的RRC建立完成消息。RRC建立完成消息中可以携带终端选择接入的SNPN。
在步骤S112中，第一基站根据RRC建立完成消息将终端接入终端选择接入的SNPN。
在一些实施例中，如图2所示，基站与终端建立RRC连接，并将终端接入终端选择接入的SNPN的过程包括：步骤S202～S210。
在步骤S202中，第一基站向终端发送连接控制建立指示，例如RRC Setup(无线资源控制建立)，该步骤可以参考现有技术，例如基站可以根据负载情况等信息判断是否允许终端接入，允许的情况下，执行步骤S204。
在步骤S204中，终端向第一基站发送无线资源控制建立完成消息，例如，RRC  Setup Complete(无线资源控制建立完成)。该步骤可以参考现有技术。
无线资源控制建立完成消息中可以包括：终端选择接入的SNPN对应的NID和PLMN标识。在第一基站支持多个SNPN的情况下，终端会选择与自己的签约的SNPN匹配的一个SNPN进行接入。在步骤S206中，第一基站向核心网网元发送初始用户设备消息。
初始用户设备消息例如为INITIAL UE MESSAGE，初始用户设备消息中包括：终端选择接入的SNPN的NID和PLMN标识。该步骤在现有信令中增加终端选择接入的NID。
在步骤S208中，核心网网元根据初始用户设备消息确定终端本次接入是否合法。
核心网网元例如为AMF(Access and Mobility Management Function，接入移动管理功能)。在一些实施例中，核心网网元是根据终端选择接入的SNPN的NID和PLMN标识与终端的签约的SNPN对应的NID和PLMN标识的比对结果确定终端本次接入是否合法的。在终端选择接入的SNPN对应的NID和PLMN标识在签约的SNPN对应的NID和PLMN标识范围内的情况下，确定终端本次接入合法，否则，不合法。核心网网元通过上述过程对终端进行鉴权。
在步骤S210中，在终端本次接入合法的情况下，核心网网元向第一基站发送下行非接入层传输信息。相应的，第一基站接收核心网网元发送的下行非接入层传输信息。
下行非接入层传输信息例如为DOWNLINK NAS TRANSPORT，可以在DOWNLINK NAS TRANSPORT中的Mobility Restriction List(移动性限制列表)信元中添加终端选择接入的SNPN对应的NID，作为Serving NID(服务NID)。该消息可以参考现有技术。上述实施例在终端初始接入的过程中，INITIAL UE MESSAGE中增加终端选择接入的SNPN对应的NID，增加核心网网元对终端的鉴权过程。
上述实施例的方法中第一基站通过广播消息将本基站支持的一个或多个SNPN对应的NID和PLMN标识进行广播，终端根据自身签约的SNPN和监听到的广播消息，选取第一基站进行初始接入，从而接入相应的SNPN。上述实施例的方案提供了一种独立组网下终端接入非公共网络的方案，通过对现有信令流程的改进实现利用非公共网络为终端提供服务。
本公开还提供一种实现终端在不同基站下的SNPN之间切换的过程，在独立组网场景中，切换过程为基于NG(Next Generation，下一代)的切换，下面分别结合图 3进行描述。
下面结合图3描述基于NG的切换过程。
图3为本公开通信方法又一些实施例的流程图。如图3所示，该实施例的方法包括：步骤S302～S310。
在步骤S302中，终端向第一基站发送测量报告，相应的，第一基站接收终端发送的测量报告。
测量报告包括：终端申请接入的SNPN对应的NID、PLMN标识和对应小区的信号质量信息，还可以参考现有技术包括其他信息。在独立组网中，不支持不同SNPN间的切换，即目标基站与源基站(第一基站)的NID和PLMN标识要相同。在测量报告中添加终端申请接入的SNPN对应的NID，以使终端切换到相同的SNPN。
在步骤S304中，第一基站根据测量报告进行切换门限值的判断并确定目标小区为第二基站对应的小区，如果符合切换条件则向核心网网元发送切换需求信息。
核心网网元例如为AMF。切换需求信息例如为Handover Required，包括：终端申请接入的SNPN对应的NID和PLMN标识以及目标小区的标识。第一基站进行切换门限值的判断，确定第二基站对应的小区作为目标小区可以参考现有技术，在此不再赘述。
在独立组网的情况下，不同的核心网网元也可以支持不同的SNPN。核心网网元对应的NID是通过NG接口建立响应信息或者核心网网元对应的更新的NID信息是通过核心网网元配置更新信令发送至第一基站的。核心网网元配置更新信令例如为AMF CONFIGRATION UPDATE，NG接口建立响应信息例如为NG SETUP REQUEST，这些信息中可以包含核心网网元对应的NID列表。
在一些实施例中，第一基站将终端申请接入的SNPN对应的NID和PLMN标识与终端在第一基站接入的SNPN对应的NID和PLMN标识进行匹配；在相匹配的情况下，第一基站将终端在第一基站接入的SNPN对应的NID和PLMN标识和各个核心网网元对应的NID和PLMN标识进行比对，确定与终端在第一基站接入的SNPN对应的NID和PLMN标识具有相同NID和PLMN标识的核心网网元，并向该核心网网元发送切换需求信息。第一基站对终端申请接入的SNPN的NID进行验证，保证终端申请接入的SNPN与当前接入的SNPN一致。进而选择合适的核心网网元发送切换需求信息。
在步骤S306中，核心网网元根据切换需求信息向第二基站发送切换请求。
在一些实施例中，核心网网元根据终端申请接入的SNPN对应的NID和PLMN标识与终端签约的SNPN对应的NID和PLMN标识的比对结果确定终端本次切换是否合法，在本次切换合法情况下，向第二基站发送切换请求。在终端申请接入的SNPN对应的NID和PLMN标识与终端签约的SNPN对应的NID和PLMN标识一致的情况下，确定终端本次切换合法。核心网通过对终端的鉴权，对终端的切换进行控制。
在一些实施例中，基站通过NG接口建立请求(例如，NG SETUP REQEST)将基站支持的一个或多个SNPN对应的NID发送至核心网网元；核心网网元可以向基站返回NG接口建立响应(NG SETUP RESPONSE)。或者，基站是通过无线接口配置更新信息(例如，RAN CONFIGURATION UPDATE)将基站支持的一个或多个SNPN对应的NID发送至核心网网元，核心网网元可以向基站返回无线接口配置更新确认消息(例如，RAN CONFIGURATION UPDATE)。基站将自身支持的一个或多个SNPN对应的NID发送至核心网，便于核心网对终端的切换进行控制。基站还可以将各个小区支持的SNPN对应的NID通过上述方法发送至核心网网元。
在一些实施例中，核心网网元将终端签约的一个或多个SNPN对应的NID和PLMN标识与第二基站支持的一个或多个SNPN对应的NID和PLMN标识进行匹配，匹配成功的情况下，向第二基站发送切换请求。或者，核心网网元将终端申请接入的SNPN对应的NID和PLMN标识与目标小区支持的SNPN对应的NID和PLMN标识进行匹配，匹配成功的情况下，向第二基站发送切换请求
切换请求例如为Handover Request，可以添加终端申请接入的SNPN对应的NID。可以在Mobility Restriction List(移动性限制列表)信元中添加终端申请接入的SNPN对应的NID。由于目前独立组网场景下，不支持终端跨SNPN切换，即终端申请接入的SNPN对应的NID和终端当前连接的SNPN对应的NID一致，终端申请接入的SNPN对应的NID为Serving NID。
在步骤S308中，第二基站向核心网网元发送切换请求确认信息，相应的，核心网网元接收第二基站发送的切换请求确认信息。
在一些实施例中，第二基站根据终端申请接入的SNPN对应的NID和PLMN标识与第二基站支持的一个或多个SNPN对应的NID和PLMN标识，确定是否允许终端切换，在允许终端切换的情况下，向核心网网元发送切换请求确认信息。在第二基站支持的一个或多个SNPN的NID和PLMN标识与终端申请接入的SNPN对应的NID和PLMN标识有交集的情况下，确定允许终端切换。或者，第二基站根据终端申请接 入的SNPN对应的NID和PLMN标识与目标小区支持的SNPN对应的NID和PLMN标识，确定是否允许终端切换，在允许终端切换的情况下，向核心网网元发送切换请求确认信息。第二基站可以对终端进行鉴权，从而对终端进行切换控制。
在步骤S310中，核心网网元根据切换请求确认信息向第一基站返回切换指令，相应的，第一基站接收核心网网元根据切换请求确认信息返回的切换指令，以便将终端切换到第二基站支持的SNPN中。
切换指令例如为Handover Command，后续切换过程可以参考现有技术。
上述基于NG接口的切换实施例中，源基站(第一基站)向核心网发送切换需求消息，核心网可以根据终端的测量报告对目标基站(第二基站)或目标小区的选择做出控制。目标基站可以对终端进行鉴权，确定是否允许接入。通过在现有切换信令中增加终端申请接入的SNPN对应的NID，实现终端在不同基站下的SNPN之间进行切换的过程。
