具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信***,例如:全球移动通讯(Global System of Mobile Communication,GSM)***、码分多址(Code Division Multiple Access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***、长期演进(Long Term Evolution,LTE)***、LTE频分双工(Frequency Division Duplex,FDD)***、LTE时分双工(Time Division Duplex,TDD)***、先进的长期演进(Advanced long term evolution,LTE-A)***、新无线(New Radio,NR)***、NR***的演进***、非授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)***、非授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)***、通用移动通信***(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、5G***或其他通信***等。
通常,传统的通信***支持的连接数有限,也易于实现。然而,随着通信技术的发展,移动通信***不仅支持传统的通信,还将支持例如设备到设备(Device to Device,D2D)通信、机器到机器(Machine to Machine,M2M)通信、机器类型通信(Machine Type Communication,MTC)、以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可应用于这些通信***。
另外,本申请实施例的通信***可以应用于载波聚合(Carrier Aggregation,CA)场景、双连接(Dual Connectivity,DC)场景、独立(Standalone,SA)布网场景等。
示例性的,本申请实施例应用的通信***100如图1所示。通信***100包括网络设备110。网络设备110可以是与终端设备120进行通信的设备。网络设备110可以为特定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。
本申请实施例中,网络设备110例如可以是GSM***或CDMA***中的基站(Base Transceiver Station,BTS);WCDMA***中的基站(NodeB,NB);LTE***中的演进型基站(Evolutional Node B,eNB或eNodeB);云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器。或者,网络设备110可以是移动交换中心、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。或者,网络设备110也可以是NTN***中的卫星。
通信***100还包括位于网络设备110覆盖范围内的至少一个终端设备120。终端设备120可以是移动的或固定的。终端设备120例如可以是用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、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。终端设备还可以是蜂窝电话、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、未来5G网络中的终端设备、未来演进的PLMN中的终端设备等,本申请实施例对此并不限定。此外,终端设备120之间可以进行终端直连(Device to Device,D2D)通信。
网络设备110可以为小区提供服务,终端设备120通过该小区对应的传输资源与网络设备110进行通信。该小区可以是网络设备110对应的小区。小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站。这里的小小区可以包括城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等。这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备,但本申请并不限于此。通信***100可以包括多个网络设备,并且每个网络设备的覆盖范围内可以包括其它数量的终端设备。此外,通信***100还可以包括网络控制器、移动性管理实体等其他网络实体。
目前,终端设备可以通过PLMN网络进行数据业务。但在一些场景中,例如办公场景、家庭场景、工厂场景中,为了能够更加有效地实现安全管理,会有当地的用户或者管理者布局本地网络或者私有网络。
对于上述垂直行业,一种可能的部署形式就是非公共网络(Non-Public Network,NPN),即通过运营商的专有网络或第三方自己的组网,以服务部分特定用户。与PLMN网络不同,在NPN网络中,将限定特定用户的接入,并且限定NPN网络与PLMN网络之间的互操作行为,例如终端设备从NPN网络不能够切换或小区重选到PLMN网络。尤其是独立NPN网络(Stand-along NPN,SNPN),其本身具有较强的独立性,使其有可能在不同的NPN 网络上需要使用不同的终端策略。
图2示出了支持NPN网络的5G网络架构。
其中,无线接入网(Radio Access Network,RAN)可以是3GPP的接入网例如基站;也可以是非3GPP的接入网。其主要用于无线资源管理、上下行数据分类和服务质量(Quality of Service,QoS)应用、与控制面网元配合完成信令处理、与用户面网元配合完成数据转发等功能。
接入和移动性管理功能(Access and Mobility Management Function,AMF)用于无线接入网络控制平面的终结点、非接入信令的终结点、移动性管理、合法监听、接入授权\鉴权等功能。
会话管理功能(Session Management Function,SMF)用于会话管理、UE的网络互连协议(Internet Protocol,IP)地址分配和管理、选择可管理用户平面功能、策略控制和收费功能接口的终结点、下行数据通知等功能。
用户平面功能(User Plane Function,UPF)用于分组路由和转发、用户面数据的QoS处理等功能。
统一数据管理(Unified Data Management,UDM)用于产生3GPP鉴权证书/鉴权参数、存储和管理5G***的永久性用户标识、订阅信息管理等功能。
策略控制功能(Policy Control Function,PCF)主要用于向终端设备、AMF和SMF,分别提供终端策略、接入和移动性管理策略、以及会话管理策略相关的参数。
应用功能(Application Function,AF)相当于第三方应用服务器,用于发起多播数据的传输。
数据网络(Data Network,DN)用于向因特网等网络传输数据、以及从因特网等网络接收数据。
身份验证服务器功能(AUthenticationServer Function,AUSF)支持3GPP接入和不受信任的非3GPP接入的认证。
其中,Ni表示通信接口,i为正整数。例如,N2为RAN与AMF之间的通信接口,N3为RAN与UPF之间的通信接口,N4为SMF与UPF之间的通信接口,N6为UPF与DN之间的通信接口。
NPN网络包括SNPN网络和CAG网络。其中,SNPN网络的封闭性更强,一般不支持SNPN网络与PLMN网络之间的互操作,例如终端设备不能从SNPN网络切换或小区重选到PLMN网络;而CAG网络在某些情况下可以支持与PLMN网络之间的互操作。
SNPN网络的标识由PLMN网络的标识和网络标识(Network Identifier,NID)组成,即SNPN ID=PLMN ID+NID。也就是说,SNPN网络的标识通过PLMN ID和NID来区分。
对于PLMN网络和NPN网络来说,PLMN ID可能是一样的,例如PLMN ID的移动设备国家代码(Mobile Country Code,MCC)都设置为999。因此,终端设备无法区分其接收到的标识信息适用于PLMN网络还是NPN网络。
在SNPN网络中,各个网元可以独立于PLMN网络而存在,即SNPN网络自己拥有例如PCF、SMF、AMF、UDM等网元,并且可以拥有自己的根秘钥、安全算法、签约信息、策略信息等,实现与PLMN网络的隔离。
由于SNPN网络的工作机制与PLMN网络的工作机制一致,这就意味着,AMF也需要向终端设备分配标识信息,例如全球唯一临时UE标识(Globally Unique Temporary Identifier,GUTI)、跟踪区标识(Tracking Area Identifier,TAI)列表(TAI list)等,以 进行接入和移动性管理。然而,由于SNPN ID=PLMN ID+NID,NPN网络下分配的GUTI和PLMN网络下的GUTI可能发生重合。终端设备接收到GUTI后,无法确定其中的标识信息用于PLMN网络还是NPN网络。
PLMN ID承载于GUTI中,例如图3所示的实施例。GUTI是网络侧为终端设备分配的临时标识,具有全球唯一性,可以定期或在一定条件下更换。该临时标识可以有效避免终端设备永久标识例如用户永久标识(SUbscription Permanent Identifier,SUPI)、国际移动用户识别码(International Mobile Subscriber Identity,IMSI)的交互,从而提高安全等级。
图3示出了5G***(5GS)中下发的5G-GUTI和演进分组核心网***(Evolved Packet System,EPS)中下发的GUTI中所包括的各个字段。上一行所示为5G核心网(5GC)对应的各个字段,下一行所示为EPC核心网对应的各个字段。
其中,在5G-GUTI中,包括PLMN ID、AMF区域编码(AMF RegionID)、AMF设置编码(AMF Set ID)、AMF指针(AMF Pointer)和5G临时移动用户识别码(5G-Temporary Mobile Subscriber Identity,5G-TMSI)。PLMN ID、AMF RegionID、和AMF Set ID可称为全球唯一AMF标识(Globally Unique AMF Identity,GUAMF)。AMF RegionID、AMF Set ID和5G-TMSI可称为5G-S-TMSI。
EPS对应的GUTI中包括PLMN ID、移动性管理实体(Mobility Management Entity,MME)组标识(MME Group ID)、MME编码(MME Code)和M-TMSI。其中,PLMN ID、MME Group ID和MME Code和称为全球唯一MME标识(Globally Unique MME Identity,GUMMEI)。MME Group ID、MME Code和M-TMSI可称为S-TMSI。
如图3所示,PLMN ID包括移动设备国家代码(Mobile Country Code,MCC)和移动设备网络代码(Mobile Network Code,MNC)。PLMN ID可以通过GUTI下发给终端设备。但是由于NPN网络和PLMN网络中GUTI是相同的,因此终端设备无法有效区分其接收到的GUTI适用于NPN网络还是用于PLMN网络。
同样的问题也存在于TAI列表和终端策略分段标识(UE Policy Section Identifier,UPSI)中。
其中,TAI包括PLMN ID和跟踪区编码(Tracking Area Code,TAC),即TAI=PLMN ID+TAC。因此,终端设备无法区分AMF下发的TAI列表用于NPN网络还是用于PLMN网络。
而对于UPSI,其部分取值在NPN网络和PLMN网络中是重叠的,如果终端设备接收到这些取值中的一个,则无法区分该UPSI对应的终端策略分段内容适用于NPN网络还是用于PLMN网络中使用的终端策略(UE policy)。
核心网网元例如PCF可以通过容器(Container)的方式,将终端策略发送给终端设备。当核心网网元没有发送终端策略,或者基于终端设备的配置,终端设备也可以选择使用本地配置的终端策略。
终端策略的下发可以通过UE配置更新(UE Configuration Update,UCU)流程来实现,PCF可以将要更新的策略(Policy)放在一个容器(Container)里,发送给AMF。AMF通过NAS消息直接转发给终端设备。
网络侧可以将终端策略分为一个或多个部分(Section),其中每一部分对应一个标识即UPSI,从而向终端设备指示相应的终端策略分段的内容。UPSI由PLMN ID和策略分段编码(Policy Section Code,PSC)组成,即UPSI=PLMN ID+PSC。PSC可以是网络中唯一的,也可以称为UPSC。但是终端设备无法根据PLMN ID区分UPSI对应的终端策略分段内容适用于NPN网络还是用于PLMN网络中使用的终端策略。
为此,本申请提供一种信息传输的方法,能够使终端设备有效地区分其接收到的标识信息所适用的网络,解决了公共网络和非公共网络中标识信息冲突的问题。
图4是本申请实施例的信息传输的方法的示意性流程图。该方法400可以应用于5G中的非公共网络,也可以应用于4G中的非公共网络。
如图4所示的实施例中,该方法400包括以下步骤中的部分或全部。
在410中,终端设备接收网络设备发送的标识信息。
在420中,终端设备根据网络设备的指示、所述标识信息的接收环境、或者所述标识信息的内容,确定所述标识信息是否用于非公共网络。
其中,该标识信息例如可以包括以下中的至少一种:GUTI、TAI和UPSI。
对于UPSI,终端设备确定所述UPSI用于非公共网络时,可以将该UPSI对应的终端策略分段的内容用于具有相同PLMN ID的非公共网络。即,该非公共网络的标识中的PLMN ID与该UE策略分段的内容对应的PLMN ID相同。其中,终端设备可以通过NAS消息或终端策略容器,接收该UPSI。
应理解,本申请实施例中,UPSI对应的终端策略分段可以指,与网络设备下发的终端策略中的某个PLMN ID对应的终端策略分段。
其中,网络设备下发的终端策略的内容中可以包括一个或者多个PLMN ID,且每个PLMN ID下包括一个或多个UPSC及其对应的策略分段内容。终端设备可以将一个PLMN ID及其对应的一个UPSC的组合,作为一个UPSI。
该非公共网络例如可以包括SNPN网络或者CAG网络。
该实施例中,终端设备可以基于网络设备的指示、其接收到的标识信息的接收环境、或者该标识信息的内容,确定该标识信息用于非公共网络还是公共网络,从而实现在相应网络中的有效通信。
如果确定该标识信息用于非公共网络,则该标识信息不再用于公共网络例如PLMN网络。也即,该标识信息仅用于非公共网络。
本申请实施例中,网络设备可以向终端设备发送标识信息,并向终端设备指示该标识信息是否用于非公共网络。或者,终端设备也可以基于自身行为,确定该标识信息是否用于非公共网络。
本申请提供三种方式,用于终端设备确定其接收到的标识信息是否用于非公共网络。下面分别进行描述。
方式1
终端设备可以基于网络设备的指示,确定其接收到的标识信息是否用于非公共网络。
该网络设备例如可以是核心网设备,比如AMF、PCF等。
例如如图5所示的实施例,该方法包括以下步骤中的部分或全部。其中,步骤520对应于上述步骤410,步骤550对应于上述步骤420。
在510中,网络设备向终端设备发送标识信息。
在520中,终端设备接收网络设备发送的该标识信息。
在530中,网络设备向终端设备发送第一指示信息。
其中,该第一指示信息用于指示该标识信息是否用于非公共网络。
在540中,终端设备接收网络设备发送的第一指示信息。
在550中,终端设备根据该第一指示信息,确定该标识信息是否用于非公共网络。
该方式中,网络设备通过第一指示信息,向终端设备指示该标识信息是否用于非公共网络。进一步地,可选地,第一指示信息中可以包括网络识别码,该标识信息用于该网络 识别码对应的非公共网络。如果第一指示信息中不包括网络识别码,则可以默认为该标识信息适用于终端设备当前所处的非公共网络。
其中,该网络识别码用于标识不同的非公共网络。该非公共网络为SNPN网络时,该网络识别码为NID;该非公共网络为CAG网络时,该网络识别码为CAG标识。
举例来说,AMF可以在下行非接入层(Non-Access Stratum,NAS)消息中携带该第一指示信息。其中,该第一指示信息用于指示NAS消息中包括的标识信息,比如GUTI、TAI或者UPSI等标识信息,是否用于非公共网络。进一步地,如果该第一指示信息中携带NID或CAG标识,则表示终端设备接收到的该标识信息用于该NID或CAG标识对应的非公共网络;如果该第一指示信息中没有携带任何NID或CAG标识,则表示该标识信息用于终端设备当前所在的非公共网络。
方式2
终端设备根据其接收到的标识信息的内容,确定该标识信息是否用于非公共网络。
在一种实现方式中,网络设备可以通过该标识信息中的第一字段的取值,向终端设备指示该标识信息是否用于非公共网络。
相应地,终端设备根据该标识信息中的第一字段的取值,确定该标识信息是否用于非公共网络。
也就是说,可以将标识信息中的第一字段的一些特定取值,默认让非公共网络来使用。网络设备向终端设备指示该标识信息用于非公共网络时,设置该第一字段的取值为该特定值。终端设备接收到该标识信息后,若其中的第一字段的取值为该特定值,则确定该标识信息用于非公共网络。
其中,该第一字段例如可以包括以下中的至少一种:承载AMF区域标识(AMF RegionID)的字段、承载AMF设置标识(AMF Set ID)的字段、承载PLMN标识的字段。
举例来说,假设第一字段为承载AMF RegionID的字段,或者为承载AMF Set ID的字段。将非公共网络看作一个网络切片,如果终端设备接收到标识信息中的AMF RegionID字段或者AMF Set ID字段的取值,是为该网络切片分配的取值,则该标识信息用于该取值对应的非公共网络。
又例如,假设第一字段为承载PLMN ID的字段。如果终端设备接收到标识信息中的PLMN ID中的MCC的取值是特定值,比如MCC=999,则该标识信息用于非公共网络。
又例如,如果终端设备接收到标识信息中的第一字段的取值,是非公共网络的网络识别码例如NID,则该标识信息用于非公共网络。
该实施例中,终端设备根据其接收到的GUTI、TAI或UPSI等标识信息中的第一字段的取值,确定这些标识信息是否适用于非公共网络。
在另一种实现方式中,网络设备可以通过是否在该标识信息中携带第二字段,向终端设备指示该标识信息是否用于非公共网络。
相应地,终端设备根据该标识信息中是否携带第二字段,确定该标识信息是否用于非公共网络。
也就是说,公共网络和非公共网络中下发的该标识信息中所包括的字段的数量不同。
该第二字段例如可以为承载网络识别码的专用字段。
这时,网络设备向终端设备指示该标识信息用于非公共网络时,可以设置该标识信息中携带该第二字段。终端设备接收到该标识信息后,若该标识信息中携带该第二字段,则确定该标识信息用于非公共网络。
例如,可以在标识信息比如GUTI、TAI或UPSI中,增加一个新字段用于承载非公共 网络的网络识别码。以SNPN网络为例,如图6所示的实施例中,用于SNPN网络的GUTI中的MNC字段和AMF Region ID字段之间增加了第二字段用来承载NID。如果终端设备接收到的GUTI中没有NID字段,则表明该GUTI用于PLMN网络;如果终端设备接收到的GUTI中有NID字段,则表明该GUTI用于SNPN网络。又如图7所示的实施例,用于SNPN网络的TAI中的MNC字段和TAC字段之间增加了第二字段用来承载NID。如果终端设备接收到的GUTI中没有NID字段,则表明该GUTI用于PLMN网络;如果终端设备接收到的GUTI中有NID字段,则表明该GUTI用于SNPN网络。
该第二字段例如可以为承载PLMN标识的字段。
这时,网络设备向终端设备指示该标识信息用于非公共网络时,可以设置该标识信息中不携带该第二字段。终端设备接收到该标识信息后,若该标识信息中不携带该第二字段,则确定该标识信息用于非公共网络。
例如,网络设备在下发GUTI时,如果GUTI中携带PLMN ID字段,则表示该GUTI用于公共网络;如果GUTI中不携带PLMN ID字段,即网络设备不下发MCC字段和MNC字段,则表示该GUTI用于非公共网络。
又例如,网络设备在下发TAI时,如果TAI中携带PLMN ID字段,则表示该GUTI用于公共网络;如果TAI中不携带PLMN ID字段,即网络设备不下发MCC字段和MNC字段,则表示该TAI用于非公共网络。
又例如,网络设备在下发UE策略例如UE策略分段管理子列表(UE policy section management sublist)时,每个UE策略下对应多个PLMN ID,每个PLMN ID又对应多个UE策略分段,其中每个UE策略分段的内容通过一个PSC来进行标识。其中,如果下发的该UE策略中携带PLMN ID字段,则其中的UE策略分段的内容用于公共网络;如果该UE策略中不携带PLMN ID字段,即网络设备不下发MCC字段和MNC字段,或者PLMN ID字段的取值为空或者为无效值,则其中的UE策略分段的内容用于具有相同PLMN ID的非公共网络,即,该非公共网络的标识中的PLMN ID与该UE策略分段的内容对应的PLMN ID相同。
该实施例中,终端设备根据其接收到的GUTI、TAI或UPSI中是否携带第二字段,确定这些标识信息是否适用于非公共网络。
方式3
终端设备可以根据该标识信息的接收环境,确定该标识信息是否用于非公共网络。
可选地,若终端设备在当前所处的非公共网络中接收到该标识信息,则终端设备确定该标识信息用于当前的该非公共网络。
例如,终端设备在当前所处的非公共网络中,接收到GUTI或TAI,则该GUTI或TAI仅在接入当前的该非公共网络时使用。
又例如,终端设备在当前所处的非公共网络中,接收到UPSI,则将该UPSI对应的终端策略分段的内容用于具有相同PLMN ID的非公共网络。
另外,可选地,若终端设备在公共网络中接收到该标识信息,则终端设备可以确定该标识信息用于公共网络。
进一步地,可选地,终端设备在当前的非公共网络中接收到该标识信息后,可以将该标识信息与该非公共网络之间进行关联,并将该关联关系进行存储。终端设备离开该非公共网络时,可以删除该标识信息及该关联关系。
基于上述方式,终端设备能够确定其接收到的标识信息用于非公共网络还是公共网络,从而实现终端设备在相应网络中的有效通信。其中,在方式1中,网络设备通过发送第一 指示信息,对该标识信息所适用的网络进行指示;方式2中,通过改变标识信息本身的结构,对该标识信息所适用的网络进行指示。而在方式3中,终端设备可以不依赖于网络设备的指示,无需改变标识信息的结构,也无需增加新的消息,而是基于自身行为,确定该标识信息所适用的网络。
可选地,该方法还可以包括:终端设备向网络设备发送第二指示信息。
其中,该第二指示信息用于指示终端设备接入非公共网络。
相应地,网络设备接收该第二指示信息。
网络设备可以根据第二指示信息,确定终端设备是否注册到该非公共网络,已确保终端设备处于正常状态。
