具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
在Rel-13ProSe中,3GPP引入了基于层3中继的终端设备到网络的中继功能,即remote终端设备可以通过relay终端设备接入网络,relay终端设备可以承担互联网协议(internet protocol,IP)层中继的功能,从而在remote终端设备和网络设备间传递数据。应理解,在Rel-13中,ProSe主要是针对公共安全类业务的。
比如,终端设备A在无网络服务区,终端设备B在有网络的服务区,终端设备A和终端设备B距离较近,则终端设备A可以通过终端设备B进行中继从而与网络进行通信。在这种情况下,终端设备A为remote终端设备,终端设备B为relay终端设备。
Relay的一种网络结构可以如图1所示。remote终端设备通过PC5接口与relay终端设备相连,remote终端设备通过relay终端设备接入到网络,relay终端设备通过Uu接口与网络设备连接,演进型分组核心网(Evolved Packet Core,EPC)通过SGi接口与公共安全应用服务器(AS)连接。其中,EPC主要由移动管理实体(Mobile Management Entity,MME)、信令网关(Signaling Gateway,SGW)、分组数据网网关(Packet Data Network GateWay,PGW)和策略与计费规则功能(Policy and Charging Rules Function,PCRF)等网元构成。
其中,remote终端设备和/或relay终端设备可以包括但不限于经由有线线路连接,如经由公共交换电话网络(Public Switched Telephone Networks,PSTN)、数字用户线路(Digital Subscriber Line,DSL)、数字电缆、直接电缆连接;和/或另一数据连接/网络;和/或经由无线接口,如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一终端设备的被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例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网络中的网络侧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。
在remote终端设备和relay终端设备进行relay功能之前,remote终端设备和relay终端设备需要被 授权。
在LTE系统中,对remote终端设备和relay终端设备的授权是ProSe功能(ProSe Function)实体通过PC3接口进行的。ProSe的一种可能的网络架构可以如图2所示。图2的网络架构中包括两个终端设备,即UE A和UE B,UE A和UE B之间通过PC5接口连接。UE A可以为remote UE且UE B可以为relay UE,或者,UE A可以为relay UE且UE B可以为remote UE。UE A和UE B可以属于一个公用陆地移动网络(Public Land Mobile Network,PLMN),也可以分属于两个PLMN。
图2的网络架构中还包括接入网设备,即演进的通用路基无线接入网(Evolved Universal Terrestrial Radio Access Network,E-UTRAN),UE A和UE B分别通过LTE-Uu接口连接到E-UTRAN。此外,图2的网络架构中还包括MME、SGW/PGW、归属签约用户服务器(Home Subscriber Server,HSS)、服务定位协议(Service Location Protocol,SLP)、ProSe Function实体以及ProSe应用服务器(ProSe Application Server)。其中,E-UTRAN通过S1接口连接到MME和SGW/PGW。UE A和UE B可以提供相关ProSe应用(ProSe Application),其和ProSe Application Server的接口为PC1接口,提供相关认证功能。ProSe Function实体与UE A和UE B之间通过PC3接口进行连接,用于ProSe Function实体对UE A和UE B进行relay授权。ProSe Function实体与HSS和SLP之间的接口分别为PC4a和PC4b,ProSe Function实体与ProSe Application Server的接口为PC2,用于ProSe业务的应用实现。
5G系统采用了如图3所示的服务化架构。该通信系统可以包括UE、接入网设备(Access Network,AN或Radio Access Network,RAN)、用户平面功能(User Plane Function,UPF)、数据网络(Data Network,DN)、鉴权服务功能(Authentication Server Function,AUSF)、接入和移动性管理功能(Access and Mobility Management Function,AMF)、会话管理功能(Session Management Function,SMF)、业务控制点(Service Control Point,SCP)、网络切片选择功能(Network Slice Selection Function,NSSF)、网络开放功能(Network Exposure Function,NEF)、网络存储功能(Network Function Repository Function,NRF)、策略控制功能(Policy Control Function,PCF)、统一数据管理(Unified Data Management,UDM)和应用层功能(Application Function,AF)。
其中,AMF负责用户的移动性和接入管理,SMF负责用户会话管理功能,UDM负责前台数据的统一处理,包括用户标识、用户签约数据、鉴权数据等。AUSF配合UDM专门负责用户鉴权数据相关的处理。NEF负责对外开放网络数据,NRF负责对网络功能(Network Function,NF)进行登记和管理,NSSF用于管理网络切片相关的信息。
各个设备之间可以具有不同的接口,例如,N1是连接UE和AMF之间的接口,N2是连接AMF和RAN之间的接口,N3是连接RAN和UPF之间的接口,N4是连接SMF和UPF之间的接口等。图3中的Nnnsf、Nnef、Nnrf、Npcf、Nudm、Nausf、Namf、Nsmf为服务化接口,所有的服务化接口都可以在同一总线(即图3中的长横线)上进行传输,因此,该通讯方式又可以理解为总线通讯方式。
从图3中可以看到,5G系统中不存在LTE系统中的ProSe Function实体和PC3接口,因此,如何对终端设备(如图3中的UE)进行relay授权是一项亟需解决的问题。另外,5G系统引入了更细粒度的relay功能,对于这些relay功能也需要分别进行授权。
鉴于此,本申请实施例提出了一种通信方法,可以实现5G系统中对终端设备的relay授权。
图4是根据本申请实施例的通信方法100的示意性图。图4所述的方法可以由终端设备执行,该终端设备例如可以为图3中所示的UE。如图4所示,该方法100可以包括以下内容中的至少部分内容。
在110中,终端设备接收核心网设备发送的第一授权信息,该第一授权信息用于指示是否授权该终端设备作为remote终端设备和/或relay终端设备。

下面结合两个实施例分别介绍本申请实施例的技术方案。
实施例1:网络设备主动向终端设备提供第一授权信息。
AF获得授权辅助信息后,可以将授权辅助信息提供给UDM。具体而言,如果AF与UDM之间有直接接口,则AF可以通过与UDM之间的接口直接将授权辅助信息发送给UDM。或者,若AF与UDM之间没有直接接口,则可以通过NEF进行授权辅助信息的中转,即AF将授权辅助信息发送给NEF,NEF再将授权辅助信息发送给UDM。
其中,授权辅助信息可以包括但不限于以下信息中的至少一项信息:
终端设备的标识信息;
终端设备是否被授权作为remote终端设备和/或relay终端设备;
针对特定业务,终端设备是否被授权作为remote终端设备和/或relay终端设备;
针对特定组,终端设备是否被授权作为remote终端设备和/或relay终端设备;
针对特定组中的特定业务,终端设备是否被授权作为remote终端设备和/或relay终端设备;
针对特定外部网络服务器DNN或特定网络切片,终端设备是否被授权作为remote终端设备和/或relay终端设备;
针对终端设备支持或者运行的通信制式,终端设备是否被授权作为remote终端设备和/或relay终端设备;
授权辅助信息适用的PLMN信息;
授权辅助信息适用的通信区域;
授权辅助信息适用的时间。
应理解,关于授权辅助信息的说明可以参考第一授权信息的描述,这里,为了避免赘述,省略其详细说明。
UDM接收到授权辅助信息后,可以保存授权辅助信息,并将授权辅助信息发送给PCF。
UDM保存授权辅助信息,如此,如果UDM之后需要使用授权辅助信息的话,可以直接获取保存的授权辅助信息,从而可以节省通信时间。
在UDM向PCF发送授权辅助信息时,可选地,UDM可以将授权辅助信息作为透明容器发送给PCF。
PCF接收到授权辅助信息后,确定是否对授权辅助信息进行更改,以得到最终提供给终端设备的第一授权信息。
其中,PCF是否对授权辅助信息进行更改可以理解为:PCF是否对授权辅助信息中的至少部分信息进行修改或删除,和/或,PCF是否添加部分信息至授权辅助信息。
作为一种示例,PCF可以在接收到授权辅助信息后,一律不对授权辅助进行更改。在该情况下,授权辅助信息与第一授权信息相同。
作为另一种示例,PCF可以在接收到授权辅助信息后,一律对授权辅助信息进行更改。可选地,协议可以规定PCF接收到授权辅助信息后一律对授权辅助信息进行更改。
作为另一种示例,PCF可以根据运营商的策略和/或本地配置信息,确定是否更改授权辅助信息。
作为另一种示例,PCF可以根据上一次接收到授权辅助信息后是否更改授权辅助信息的情况,确定本次是否更改授权辅助信息。比如,若上一次PCF未更改授权辅助信息,则PCF可以确定本次不更改授权辅助信息。或者,若上一次PCF未更改授权辅助信息,则PCF可以确定本次更改授权辅助信息。
作为另一种示例,PCF可以根据当前时刻的网络状况,确定是否更改授权辅助信息。比如,若当前时刻网络状况较好,则PCF可以更改授权辅助信息;若当前时刻网络状况较差,则PCF可以不更改授权辅助信息。
在PCF确定更改授权辅助信息的情况下,可选地,PCF可以根据运营商的策略和/或本地配置信息,更改授权辅助信息,得到第一授权信息。
之后,在一种实现方式中,PCF可以将第一授权信息发送给AMF。可选地,PCF可以将第一授权信息封装在透明容器中,发送给AMF。
在AMF接收到第一授权信息后,AMF可以确定是否将第一授权信息发送给终端设备。
作为一种示例,AMF可以在任何情况下都将第一授权信息发送给终端设备。
作为另一种示例,AMF可以根据终端设备是否支持中继功能的能力信息确定是否将第一授权信息发送给终端设备。也就是说,若终端设备不支持中继功能,则AMF可以不将第一授权信息发送给终端设备;若终端设备支持中继功能,则AMF可以将第一授权信息发送给终端设备。
作为另一种示例,AMF可以根据终端设备当前是否在进行中继功能的情况,确定是否将第一授权 信息发送给终端设备。比如,若终端设备当前时刻正在使用中继功能,则AMF可以不将第一授权信息发送给终端设备;若当前时刻终端设备未进行中继功能,则AMF确定将第一授权信息发送给终端设备。
作为另一种示例,AMF可以根据终端设备的优先级,确定是否将第一授权信息发送给终端设备。比如,若终端设备的优先级较低,则AMF可以将第一授权信息发送给高优先级的终端设备,而不发送给该终端设备;若终端设备的优先级较高,则AMF可以将第一授权信息发送给该终端设备。
作为另一种示例,AMF可以根据终端设备当前与网络设备之间的距离,确定是否将第一授权信息发送给终端设备。比如,若第一授权信息指示允许终端设备作为relay终端设备,当终端设备当前与网络设备之间的距离较远时,则AMF可以不将第一授权信息发送给终端设备。再比如,若第一授权信息指示允许终端设备作为remote终端设备,当终端设备当前与网络设备之间的距离较近时,则AMF可以不将第一授权信息发送给终端设备。
若AMF未将第一授权信息发送给终端设备,则AMF可以向PCF发送第二反馈信息,第二反馈信息用于反馈AMF未将第一授权信息发送给终端设备。进一步地,第一反馈信息中还可以包括AMF未将第一授权信息发送给终端设备的原因。比如,第一反馈信息可以包括终端设备不支持relay功能。
若AMF确定将第一授权信息发送给终端设备,则AMF可以将第一授权信息封装在NAS协议数据单元(Protocol Data Unit,PDU)中传递给终端设备。即AMF不解析第一授权信息,只是将第一授权信息封装在NAS消息中。此时,可选地,AMF可以向终端设备指示NAS消息承载第一授权信息。
或者,AMF可以在解析第一授权信息后,将第一授权信息发送给终端设备。
在另一种实现方式中,PCF可以将第一授权信息发送给SMF。可选地,PCF可以将第一授权信息封装在透明容器中,发送给SMF。之后,SMF可以将第一授权信息发送给终端设备。
应理解,SMF接收到第一授权信息后的后续行为可以参考AMF的行为,此处不再赘述。
终端设备接收到NAS消息后,可以确定是否应用第一授权信息。
在一种实现方式中,终端设备可以在任何情况下都确定应用第一授权信息。
在另一种实现方式中,终端设备可以根据自己支持的能力信息和/或用户的偏好信息,确定是否应用第一授权信息。
其中,终端设备的能力例如可以包括基带能力,射频能力,测量能力,终端等级(category),资源分配能力、通信模式能力以及载波聚合(Carrier Aggregation,CA)能力等。
例如,第一授权信息适用的通信模式为组播通信模式,终端设备不支持组播通信模式能力,则终端设备可以确定不应用第一授权信息。
例如,第一授权信息是针对业务的业务为微信,用户使用微信A概率特别高,因此,终端设备确定应用第一授权信息。
在终端设备确定是否应用第一授权信息后,终端设备可以向AMF发送第一反馈信息,第一反馈信息包括终端设备确定的是否应用第一授权信息的结果。AMF接收到第一反馈信息后,可以将第一反馈信息发送给PCF。
其中,终端设备向AMF发送的第一反馈信息承载于NAS消息中。
应理解,在本申请实施例中,“第一”和“第二”仅仅为了区分不同的对象,但并不对本申请实施例的范围构成限制。
下面结合图5对实施例1的通信方法的具体实现方式进行示例性说明。
S210:AF向UDM发送授权辅助信息。
S220:UDM保存授权辅助信息:
S230:UDM将授权辅助信息作为透明容器发送给PCF。
S240:PCF接收到授权辅助信息后,对授权辅助信息进行更改,得到第一授权信息,并将第一授权信息封装在透明容器中发送给AMF。
S250:AMF将接收到的第一授权信息封装在NAS PDU中传递给终端设备。
S260:终端设备接收到NAS消息后,根据自身的能力信息判断应用第一授权信息,并向AMF发送第一反馈信息,第一反馈信息用于反馈终端设备应用第一授权信息。
S270:AMF接收到第一反馈信息后,将第一反馈信息发送给PCF。
实施例2:网络设备基于终端设备的请求提供第一授权信息。
当终端设备需要发起relay业务时,终端设备可以向AMF或SMF发送授权请求信息,该授权请求信息用于请求作为relay终端设备和/或remote终端设备。
可选地,授权请求信息可以承载于NAS消息中。
其中,在以下情况中,可以认为终端设备需要发起relay业务:
情况1:应用层发送relay相关业务的请求;
情况2:该终端设备接收到其他终端设备作为remote的relay请求,此时,该终端设备可以请求作为relay终端设备;
情况3:该终端设备与网络设备之间的距离较远,可能无法被网络设备服务到,此时,该终端设备可以请求作为remote终端设备。
为了描述方便,下述实施例将以终端设备向AMF发送授权请求信息为例进行说明,但本申请并不限于此。
AMF接收到授权请求信息后,可以将授权请求信息发送给PCF。PCF可以基于授权请求信息和授权辅助信息,判断是否允许终端设备的授权请求。PCF确定是否允许终端设备的授权请求后,可以向AMF发送授权请求响应信息,该授权请求响应信息用于指示是否允许终端设备的授权请求。
若PCF没有授权辅助信息,则PCF可以从UDM获取。作为一种示例,UDM可以将保存的授权辅助信息封装在透明容器中,发送给AMF。作为另一种示例,若UDM没有保存授权辅助信息,则UDM可以向AF请求提供授权辅助信息,从而AF可以将授权辅助信息提供给UDM,UDM再将授权辅助信息发送给AMF。
PCF接收到授权辅助信息后,确定是否更改授权辅助信息,以得到第一授权信息。PCF确定是否更改授权辅助信息的实现方式可以参考实施例1,此处不做过多描述。
可选地,授权请求信息中还可以包括以下信息中的至少一项信息(为了描述方便,称为relay授权的对应信息):终端设备的标识信息、授权请求信息针对的特定业务、授权请求信息针对的特定组、授权请求信息针对的特定组中的特定业务、授权请求信息针对的特定DNN或网络切片、授权请求信息针对的通信制式、授权信息针对的PLMN信息、授权信息针对的通信区域、授权信息针对的适用时间。
应理解,关于relay授权的对应信息的具体描述可以参考第一授权信息的描述,为了内容的简洁,此处不再进行过多描述。
在这种情况下,若PCF允许终端设备的授权请求,则PCF可以针对relay授权的对应信息,向AMF提供目标对象为终端设备的第一授权信息。如此,可以节省信令开销,提高通信效率。
可选地,若授权请求信息中不包括relay授权的对应信息,则PCF可以将所有的第一授权信息提供给终端设备。
需要说明的是,终端设备接收到第一授权信息后想后续行为,实施例1已有详细阐述,此处不再赘述。
下面结合图6对实施例2的通信方法的具体实现方式进行示例性说明。
