当前,普通的终端用户会通过公共网络进行数据业务,但在办公、家庭等场景中,为了能够更加有效安全的管理,会有当地的用户或者管理者布局本地网络或者私有网络等非公共网络(Non-public Network,NPN)。NPN可以包含多种部署方式,例如可以为独立部署非公共网络(Stand-alone Non-public Network,SNPN)。
其中,公共网络可以为公共陆地移动网络(Public Land Mobile Network,PLMN)。
应理解,NPN中的网元可以独立于PLMN存在,即自己拥有策略控制功能网元(Policy Control Function,PCF)、会话管理网元(Session Management Function,SMF)、接入与移动性管理网元(Access and Mobility Management Function,AMF)、接收统一数据网元(Unified Data Management,UDM)等网元,并且有自己的根秘钥、安全算法、签约信息、策略信息等实现与PLMN的隔离。在终端设备初始接入时,由终端设备进行SNPN选择,并将选择的 SNPN通知给网络设备。
示例性的,图1为现有的一种终端设备选择SNPN的流程示意图。如图1所示,该终端设备选择SNPN的流程包括步骤S101至步骤S111。
S101、接入网设备发送广播消息,该消息中包括支持的SNPN标识。
其中,SNPN标识的格式可以为PLMN ID+NPN ID。
S102、终端设备根据广播消息中支持的SNPN标识选择SNPN标识作为被选中的SNPN标识。
S103、终端设备向接入网设备发送无线资源控制(Radio Resource Control,RRC)连接建立请求(RRC Connection Setup Request)消息。
其中,RRC连接建立请求消息种携带有临时移动用户标识(Serving-Temporary Mobile Subscriber Identity,S-TMSI)和RRC建立原因值。
S104、接入网设备向终端设备返回RRC连接建立(RRC Connection Setup)消息。
S105、终端设备向接入网设备发送RRC连接建立完成(RRC Connection Setup Complete)消息。
其中,RRC连接建立完成消息中携带有被选中的SNPN标识以及非接入层(NAS)信息单元(container)。NAS container中包括NAS消息-注册请求(Registration Request)消息,注册请求消息中携带有终端设备的标识,该终端设备的标识可以包括5G全局唯一临时终端标识(5G Globally Unique Temporary UE Identity,5G GUTI)、用户隐藏标识(Subscription Concealed Identifier,SUCI)(当终端设备不存在5G GUTI时)、终端设备的安全能力、请求的网络切片(Network Slice Selection Assistance Information,NSSAI)以及上次注册的跟踪区标识(Tracking Area Identity,TAI)等信息。
S106、接入网设备根据RRC连接建立完成消息中携带的被选中的SNPN标识选择AMF。
S107、接入网设备向选中的AMF发送初始终端消息(Initial UE message)。
其中,该Initial UE message中携带NAS container、RRC建立原因值、终端设备的位置信息和被选中的SNPN标识。该终端设备的位置信息由PLMN ID、小区标识和跟踪区域代码(Tracking Area Code,TAC)组成。
S108、AMF触发身份认证(authentication)过程。
应理解,在authentication过程中,终端设备和网络设备所使用的服务网络名(serving network name)都是被选中的SNPN标识。在authentication过程,终端设备和网络设备需要使用serving network name来推导出安全参数(例如,K AUSF、RES*等)。
S109、AMF向接入网设备返回终端上下文建立请求(UE context Setup Request)消息,该消息中包括承载于NAS container中的注册接受(Registration Accept)消息、安全参数、允许的NSSAI和5G截短的临时一点用户标识(5G Short Temporary Mobile Subscriber Identity,5G-S-TMSI)。Registration Accept 消息中携带允许的NSSAI、TAI列表、5G GUTI等参数。
S110、接入网设备向AMF返回终端上下文建立响应(UE context Setup Response)消息。
S111、接入网设备向终端设备发送RRC消息,该RRC消息包含上述NAS container。
S112、终端设备向接入网设备发送RRC消息,用于发送NAS container,该NAS container中包括注册完成(Registration Complete)消息,该Registration Complete消息用于确认5G GUTI生效。
S113、接入网设备向AMF发送上行非接入层传输(Uplink NAS Transport)消息,该消息中携带NAS container。
相关技术中,当网络切换只发生在当前的SNPN网络时,服务网络名(serving network name)不会发生变化,终端设备和网络设备仍然使用终端设备在初始接入时选择的SNPN的标识进行身份认证。
示例性的,当发生网络切换时,源接入网设备可以向源AMF发送切换请求,该切换请求中包含有目的标识,该目的标识中包含有切换后的目的PLMN的标识。
示例性的,当发生网络切换时,终端设备在完成切换后,可以在目标小区想AMF发送注册消息,该注册消息中包含5G GUTI等参数,AMF向终端设备返回新的5G GUTI。
应理解,若终端设备使用了PLMN网络,并发生了切换过程后,终端设备及网络设备在Authentication过程中所使用的serving network name进行推导安全参数的时包括以下两种方式:
在第一种方式中,若目的小区不是共享网络小区,终端设备使用系统广播消息中的PLMN ID作为serving network name。
在第二种方式中,若目的小区是共享网络小区并且终端设备存在有效的5G GUTI,终端设备使用5G GUTI中的PLMN ID部分作为serving network name。
基于此,在相关技术中,接入网设备即使选择了新的PLMN ID为终端设备服务,终端设备也能即时获知,并且也能使用其作为serving network name。
需要说明的是,SNPN可以使用PLMN ID及网络标识(network identifier,NID)的组合来标识,不同的SNPN可以具有相同的PLMN ID,不同的NID。因此,通过5G GUTI(格式为<5G GUTI>=<MCC><MNC><AMF Identifier><5G-TMSI>,其中<AMF Identifier>=<AMF Region ID><AMF Set ID><AMF Pointer>)中的PLMN ID并不能准确的表征当前的注册的SNPN ID。
然而,当发生SNPN之间的切换时,若仍旧使用终端设备在初始接入时选择的SNPN的标识进行身份认证,会导致身份认证失败。
为解决上述问题,本申请实施例提供一种通信方法及装置,网络设备通过向终端设备发送第一信息来指示终端设备切换SNPN后的第一SNPN的标 识。通过该方式,在SNPN切换过程中或者SNPN切换后,将网络设备侧选择的第一SNPN的标识通知终端设备,使得终端设备和网络设备均使用第一SNPN的标识作为服务网络名,从而避免了服务网络名不一致而导致的推导出的安全参数不同造成的身份认证失败,防止网络设备释放终端设备的连接,提高了用户体验。
下面对于本申请的应用场景进行举例说明。
图2为本申请实施例提供的一种通信方法的场景示意图。如图2所示,终端设备101和网络设备102之间通信。在终端设备101切换SNPN的过程中或切换SNPN后,网络设备102向终端设备发送第一消息,来指示终端设备切换SNPN后或要切换到的第一SNPN的标识。
其中,终端设备101包括但不限于卫星或蜂窝电话、可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
网络设备102可以为接入网设备,也可以为核心网设备。若网络设备102为接入网设备,其可以在特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。可选地,该网络设备102可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。若网络设备102为核心网设备,其可以包括各种类型的网络,例如AMF、PCF、SMF等。
下面以终端设备或网络设备等通信设备为例,以具体地实施例对本申请实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图3为本申请实施例提供的一种通信方法的信令交互图,本实施例涉及 的是终端设备如何确定切换SNPN后的第一SNPN的标识的过程。如图3所示,该方法包括:
S201、网络设备向终端设备发送第一信息,第一信息用于指示终端设备切换独立部署非公共网络SNPN后或要切换到的第一SNPN的标识。
在本申请中,当终端设备切换SNPN时或切换SNPN后,网络设备可以向终端设备发送第一信息,来指示终端设备切换SNPN后或要切换到的第一SNPN的标识。
应理解,在本申请中,第二SNPN可以为切换前的SNPN,第一SNPN可以为切换后或要切换到的SNPN。
在一些实施例中,第一SNPN的标识可以包括公共陆地移动网(Public Land Mobile Network,PLMN)的标识和网络标识(NID)。
应理解,本申请实施例对于第一信息如何指示第一SNPN的标识不做限制,在一些实施例中,第一信息中可以直接包含有第一SNPN的标识。在另一些实施例中,若终端设备切换SNPN前的第二SNPN的标识对应的PLMN和第一SNPN的标识对应的PLMN的标识相同,则第一信息中包含有第一SNPN对应的NID。
其中,第二SNPN的标识对应的PLMN的标识用于和第二SNPN对应的PLMN的标识组成第一SNPN的标识。相应的,终端设备在接收到第一信息后,可以根据第一SNPN的标识对应的NID和第二SNPN的标识对应的PLMN的标识,确定第一SNPN的标识。
示例性的,当终端设备接收到第一信息后,可以采用PLMN ID+NID的方式,组合成第一SNPN的标识。
应理解,本申请实施例对于网络设备如何向终端设备发送第一信息也不做限制。下面提供两种可用的网络设备发送第一信息的方式。
在第一种方式中,第一信息承载于SNPN的切换指令(Handover Command)中,该SNPN的切换指令用于指示将第二SNPN切换为第一SNPN。
示例性的,接入网设备(source NG-RAN)可以将选中的第一SNPN的标识通过切换指令发送给终端设备,该第一SNPN的标识可以包括在现有的目的标识(target ID)中。可选的,上述第一信息可以也可以通过新增信息单元的方式承载于切换指令中。
在第二种方式中,第一信息承载于切换SNPN后的注册接受消息或配置更新消息中。
在一些实施例中,终端设备可以通过接入网设备向核心网设备(AMF)发送注册请求消息,该注册请求消息中包括有5G GUTI、终端设备的安全能力和请求的NSSAI等参数。随后,核心网设备(AMF)向终端设备返回注册接受消息,该注册接受消息中包含有新的5G GUTI和上述第一信息。随后,终端设备可以向核心网设备(AMF)返回注册完成消息,该注册完成消息或配置更新确认消息用于确认5G GUTI有效。
在另一些实施例中,在完成切换后,核心网设备(AMF)可以向终端设备发送配置更新(UE configuration Update Command)消息,该配置更新消息中可以包括新的5G GUTI、注册的SNPN ID或NID(即,第一信息)。随后,终端设备向核心网设备(AMF)返回配置更新确认(UE configuration update ACK)消息,该配置更新确认消息中包含有第一SNPN的标识。
其中,第一信息具体可以承载于5G GUTI或第一SNPN的标识对应的独立信息单元中。5G GUTI中包含有目标八位字节,该目标八位字节用于承载第一信息。
示例性的,表1为增加八位字节以携带第一信息的示意表。如表1所示,可以在原5G GUTI格式的末尾增加一个八位字节(Octet)15,从而在Octet15中添加NID或第一SNPN的标识。

S202、终端设备根据第一信息,确定第一SNPN的标识。
在本步骤中,当终端设备接收到网络设备发送的第一信息后,可以根据第一信息,确定第一SNPN的标识。
应理解,本申请实施例对于如何确定第一SNPN的标识不做限制,在一些实施例中,若第一消息中直接包括第一SNPN的标识,相应的,终端设备可以直接从第一信息中获取出第一SNPN的标识。在另一些实施例中,当终端设备切换SNPN前的第二SNPN的标识对应的PLMN的标识和第一SNPN的标识对应的PLMN的标识相同时,第一信息中可以只包括第一SNPN的标识对应的NID。相应的,终端设备可以将第二SNPN对应的的PLMN的标识和第一信息中的第一SNPN的标识对应的NID组合成第一SNPN的标识。
在一些实施例中,第一SNPN的标识由终端设备的接入层转发至终端设备的非接入层,终端设备的非接入层用于将服务网络名由第二SNPN的标识替换为第一SNPN的标识。
示例性的,当终端设备的接入层(AS)接收到第一SNPN的标识后,可以将第一SNPN的标识转发给终端设备的NAS,终端设备的NAS可以将第一SNPN的标识作为注册的SNPN的标识,即,将服务网络名由第二SNPN的 标识替换为第一SNPN的标识。相应的,若AS只转发了NID,则AS将NID转发给NAS后,NAS可以将NID组合成第一SNPN的标识,再将第一SNPN的标识作为注册的SNPN的标识。
在一些实施例中,终端设备接收到第一信息后,还可以使用第一SNPN的标识作为服务网络名进行身份认证。
本申请实施例提供的通信方法,终端设备接收网络设备发送的第一信息,该第一信息用于指示终端设备切换独立部署非公共网络SNPN后的第一SNPN的标识。通过该方式,在SNPN切换过程中或者SNPN切换后,将网络设备侧选择的第一SNPN的标识通知终端设备,使得终端设备和网络设备均使用第一SNPN的标识作为服务网络名,从而避免了服务网络名不一致而导致的推导出的安全参数不同造成的身份认证失败,防止网络设备释放终端设备的连接,提高了用户体验。

在一些实施例中,终端设备的AS接收到第一SNPN的标识或NID后,可以将第一SNPN的标识或NID转发给NAS。对于第一SNPN的标识,NAS直接将其注册为SNPN ID。对于NID,NAS可以将NID构建成SNPN ID(SNPN ID为PLMN ID与NID的组合),再将其注册为SNPN ID,即,将服务网络名由第二SNPN的标识替换为第一SNPN的标识。
图7为本申请实施例提供的再一种通信方法的信令交互图。本申请实施例涉及的是第一信息承载于切换完成后的注册接受消息的情况。如图7所示,该方法包括:
S601、终端设备向AMF发送注册请求消息。

S602、AMF向终端设备发送注册接受消息。
其中,该注册接受消息中包含有5G GUTI和第一信息(可以为第一SNPN,也可以为NID)。
应理解,上述第一信息可以单独存储在信息单元中,也可以存储在5G GUTI中,5G GUTI中包含有目标八位字节,目标八位字节用于承载第一信息。
S603、终端设备向AMF返回注册完成消息,该注册完成消息用于确定5G GUTI有效。
需要说明的是,本实施例涉及的AMF和接入网设备等网络设备,可以为切换后或要切换的第一SNPN对应的网络设备,即图6所涉及的第一AMF和 第一接入网设备。
图8为本申请实施例提供的又一种通信方法的信令交互图。本申请实施例涉及的是第一信息承载于切换完成后的配置更新消息的情况。如图8所示,该方法包括:
