Description

无线通信的方法、用户设备及网络设备 技术领域
本申请涉及通信技术领域,并且更为具体地,涉及无线通信的方法、用户设备及网络设备。
背景技术
为了指示在不同的公共陆地移动网络(public land mobile network,PLMN)适用的用户设备(user equipment,UE)策略规则,网络设备在为UE配置UE策略规则时,会指示不同的UE策略规则对应的PLMN ID。然而,对于一些传统的UE(例如,支持R17或之前协议的UE)而言,可能只支持HPLMN来配置UE策略规则,也就是说,当UE策略规则中仅包含本地PLMN的PLMN ID时,UE不会报错。当UE策略规则中包含除本地PLMN之外的其他PLMN(例如,访问PLMN)的PLMN ID时,UE会报错。因此,若直接下发带有其他PLMN的PLMN ID的UE策略规则,那么此类UE可能无法再使用UE策略规则。

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。为了便于理解本申请,下文先介绍本申请实施例适用的架构、涉及的通信过程及术语。
图1为本申请实施例适用的无线通信系统的示意图。如图1所示,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)标准组发布的第五代(5th generation,5G)系统或新无线(new radio,NR)网络架构,包括:终端设备(又称“用户设备(user equipment,UE)”101、支持3GPP技术的接入网设备102(包括无线接入网(radio access network,RAN)或接入网(access network,AN))、用户面功能(user plane function,UPF)网元105、接入和移动性管理功能(access and mobility management function,AMF)网元103、会话管理功能(session management function,SMF)网元104、策略控制功能(policy control function,PCF)网元106、应用功能(application function,AF)网元109、数据网络(data  network,DN)108、网络切片选择功能(Network Slice Selection Function,NSSF)111、鉴权服务功能(Authentication Server Function,AUSF)110、统一数据管理功能(Unified Data Management,UDM)107。
需要说明的是,图1中示出的网络架构并不构成对该5G网络架构的限定,具体实现时,该5G网络架构可以包括比图示更多或更少的网元,或者组合某些网元等。另外,图1中以(R)AN的方式表征AN或RAN。
终端设备101可以是用户设备(user equipment,UE)、终端、手持终端、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant,PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop,WLL)台、机器类型通信(machine type communication,MTC)终端、具有无线通信功能的手持设备、计算设备、连接到无线调制解调器的处理设备、无人机、车载设备、可穿戴设备、物联网中的终端、虚拟现实设备、未来通信系统(例如,6G)网络中的终端设备、未来演进的公共陆地移动网络(public land mobile network,PLMN)中的终端等。
接入网设备102是终端设备通过无线方式接入到该网络架构中的接入设备,主要负责空口侧的无线资源管理、服务质量(quality of service,QoS)管理、数据压缩和加密等。例如:基站NodeB、演进型基站eNodeB、5G移动通信系统或新无线(new radio,NR)通信系统中的基站、未来移动通信系统中的基站等。
UPF网元105、AMF网元103、SMF网元104、PCF网元106为3GPP核心网络的网元(简称:核心网网元)。UPF网元105可以称为用户面功能网元,主要负责用户数据的传输,其他网元可以称为控制面功能网元,主要负责认证、鉴权、注册管理、会话管理、移动性管理以及策略控制等,以保障用户数据可靠稳定的传输。
UPF网元105(或者简称“UPF”)可以用于转发和接收终端的数据。例如,UPF网元可以从数据网络接收业务的数据,通过接入网设备传输给终端;UPF网元还可以通过接入网设备从终端接收用户数据,转发到数据网络。其中,UPF网元为终端分配和调度的传输资源是由SMF网元管理控制的。终端与UPF网元之间的承载可以包括:UPF网元和接入网设备之间的用户面连接,以及在接入网设备和终端之间建立信道。其中,用户面连接为可以在UPF网元和接入网设备之间建立传输数据的服务质量(quality of service,QoS)流(flow)。
AMF网元103(或者简称“AMF”)可以用于对终端接入核心网络进行管理,例如:终 端的位置更新、注册网络、接入控制、终端的移动性管理、终端的附着与去附着等。AMF网元还可以在为终端的会话提供服务的情况下,为该会话提供控制面的存储资源,以存储会话标识、与会话标识关联的SMF网元标识等。
SMF网元104(或者简称“SMF”)可以用于为终端选择用户面网元、为终端重定向用户面网元、为终端分配因特网协议(internet protocol,IP)地址,建立终端与UPF网元之间的承载(也可以称为会话)、会话的修改、释放以及QoS控制。
PCF网元106(或者简称“PCF”)用于向AMF网元103、SMF网元104提供策略,如QoS策略、切片选择策略、UE策略等。在一些实现方式中,PCF可以管控策略的下发、更新等。
AF网元109(或者简称“AF”)用于与3GPP核心网网元交互支持应用影响数据的路由,访问网络暴露功能,与PCF网元之间交互以进行策略控制等。
DN 108可以为如IP多媒体服务(IP multi-media service,IMS)网络、互联网等为用户提供数据服务。在DN 108中可以有多种应用服务器(application server,AS),提供不同的应用业务,比如运营商业务,互联网接入或者第三方业务等,AS可以实现AF网元的功能。
NSSF 111用于网络切片的选择,支持的功能有:选择为UE服务的网络切片实例集;确定允许的网络切片选择辅助信息(network slice selection assistance information,NSSAI),以及在需要时确定到签约的单一网络切片选择辅助信息(single-network slice selection assistance information,S-NSSAI)的映射;确定已配置的NSSAI,以及在需要时确定到签约的S-NSSAI的映射;确定可能用于查询UE的AMF集,或基于配置确定候选AMF的列表。
AUSF 110用于接收AMF 103对终端进行身份验证的请求,通过向UDM 107请求密钥,再将下发的密钥转发给AMF 103进行鉴权处理。
UDM 107包括用户签约数据的产生和存储、鉴权数据的管理等功能,支持与外部第三方服务器交互。
应理解,图1中的各网元既可以是硬件设备中的网络元件,也可以是在专用硬件上运行的软件功能,或者是平台(例如,云平台)上实例化的虚拟化功能。需要说明的是,在上述图所示的网络架构中,仅仅是示例性说明整个网络架构中所包括的网元。在本申请实施例中,并不限定整个网络架构中所包括的网元。
如上文介绍,在上述通信系统中与UE策略相关的网元可以包括PCF、AMF等,下文结合图2介绍本申请实施例适用的UE策略配置过程。
UE策略配置过程
图2是本申请实施例适用的UE策略配置过程的流程图。图2所示的方法包括步骤S210至步骤S260。
在步骤S210中,PCF确定是否更新UE策略。
需要说明的是,若PCF并没有要更新UE策略,则图2所示的流程中可以不包含步骤S210。若PCF确定要更新UE策略,图2所示的流程中会包含步骤S210。另外,若PCF确定要更新UE策略,图2所示的流程又称为“UE配置更新(UE configuration update,UCU)”流程。
在步骤S220中,PCF向AMF发送通信服务请求。
在一些实现方式中,上信服务请求可以携带容器(container),该容器中包含UE策略的相关信息。例如,UE策略的内容或UE策略标识等等。
上述通信服务请求可以通过N1、N2消息传输。因此,通信服务请求又可以表示为“Namf_通信_N1N2消息传输(Namf_Communication_N1N2 Message Transfer)”。
在步骤S230中,网络侧触发服务请求(network triggered service request),以便网络可以与UE进行通信。
在步骤S240中,AMF向UE发送UE策略。
在一些实现方式中,上述UE策略可以封装在容器中,该容器可以是PCF发送给AMF的容器,相应地,AMF在接收该容器之后,可以直接将容器透传给UE。其中,透传可以理解为AMF不感知或不修改容器。
在另一些实现方式中,上述UE策略或者容器,可以由AMF通过NAS消息(或者说下行NAS消息)发送给UE。
在步骤S250中,UE向AMF发送UE策略传输结果。
在一些实现方式中,上述UE策略传输结果用于指示UE是否成功接收UE策略。
在步骤S260中,AMF向PCF发送N1消息通知(表示为“Namf_N1MessageNotify”),来告知PCF上述UE策略传输结果。
在一些实现方式中,上述N1消息通知可以称为“管理UE策略完成消息(Manage UE policy complete)”。
需要说明的是,上述步骤S220和步骤S260可以包含两个消息即请求和针对请求的响应。图2所示的方法中仅示出了两个步骤的请求,并未示出两个针对上述两个请求的响应。
另外,如上文介绍的PCF可以将容器发送给UE,以传输UE策略之外,相反地,UE也可以通过容器向PCF发送容器,此时,容器可以通过NAS消息(或者说上行NAS消 息),由UE发送给AMF,并由AMF透传给PCF。
在图2所示的过程中,为了传输UE策略,在下行NAS和上行NAS消息中引入“UE策略容器(UE policy container)”的原因值,例如,可以在有效载荷容器(payload container)中增加UE策略容器原因值。相应地,AMF在获取到UE策略容器原因值之后,可以执行透传功能,以将容器透传给UE或PCF。
UE策略
UE策略可以包括UE路由选择策略(UE route selection policy,URSP)以及接入网发现和选择策略(access network discovery and selection policy,ANDSP)等,下文以URSP为例介绍。
URSP可以指示应用数据与PDU会话的绑定关系,另外,URSP还可以指示UE需要建立什么样的PDU会话来传输应用数据。通常,URSP可以包括一条或多条URSP规则。下文结合表1介绍URSP规则。
表1:URSP规则的结构
Figure PCTCN2022093691-appb-000001
参见表1可知,URSP规则可以包括以下信息中的一种或多种:规则优先级(rule precedence)、业务描述符(traffic descriptor,TD)、应用描述符(application descriptors)、IP描述符(IP descriptors)、域描述符(domain descriptors)、非IP描述符(Non-IP descriptors)、 数据网络名称(data network name,DNN)、连接能力(connection capabilities)、路由选择描述符(route selection descriptor,RSD)列表。
需要说明的是,URSP中的每个URSP规则的规则优先级不同。或者说,URSP中不同的URSP规则对应不同的规则优先级。
通常,当应用数据的特征与URSP规则中的业务描述符匹配后,基于URSP规则中RSD建立的PDU会话便可以用来传输该应用数据,即上文介绍的应用数据与PDU会话绑定。下文结合表2介绍URSP规则中的RSD列表。通常,RSD列表中可以包括一个或多个RSD。
表2:RSD的结构
Figure PCTCN2022093691-appb-000002
参见表2可知,RSD可以包括以下信息中的一种或多种:RSD优先级(route selection descriptor precedence)、路由选择组件(route selection components)、会话和服务连续模式选择(session and service continuity mode selection,SSC mode selection)、网络切片选择(network slice selection)、DNN选择(DNN selection)、PDU会话类型选择(PDU session type selection)、无缝卸载指示(Non-Seamless offload indication)、接入类型优先级(access  type preference)、路由选择验证标准(route selection validation criteria)、时间窗(time window)、位置标准(location criteria)。
需要说明的是,一个RSD中的各个信息可能是一个单一值,也可能包含多个值。例如,S-NSSAI和DNN的值可以是一个或多个。因此,每个RSD可以对应一个或多个参数组合,每个参数组合为一套PDU会话的特征,业务描述符对应的业务数据可以在RSD的某一个参数值组合对应的PDU会话中进行传输。当有业务描述符描述的应用数据流出现时,UE可以根据对应的RSD选取一个参数组合,发起PDU会话建立请求。
下文以表1表2所示的URSP规则为例结合图3,介绍UE为应用数据1绑定PDU会话的方法。图3所示的方法包括步骤S310至步骤S324。
在步骤S310中,UE检测到应用数据1。
参见表1,URSP规则中的业务描述符可以用于描述一种应用数据的特征。通常,应用数据1的特征与业务描述符匹配时,该业务描述符所在的URSP规则与应用数据1匹配,也就是说,UE传输应用数据1时可以使用该URSP规则。相反地,应用数据1的特征与业务描述符不匹配时,该业务描述符所在的URSP规则与应用数据1不匹配,也就是说,UE传输应用数据1时不可以使用该URSP规则。
以微博的应用数据为例,假如微博的的应用服务器的IP地址为IP@1~9的范围,因此URSP规则中配置范围为IP@1-9的业务描述符以及对应的RSD可以用于微博业务的数据传输。当UE有应用数据需要传输且携带其应用数据的IP数据包的目的IP地址落在IP@1-9范围时,即认为该应用数据与微博的业务描述符匹配。UE可以根据该业务描述符对应的URSP规则中的RSD,将匹配的应用数据包绑定到对应的PDU会话进行传输。
以IMS业务为例,与IMS的应用数据匹配的业务描述符为IMS DNN。也就是说,业务描述符为IMS DNN的URSP规则可以用其RSD对应的PDU会话传输IMS的应用数据。
在步骤S311中,UE考察URSP中规则优先级最高的URSP规则。
当应用层出现数据(或者说,UE检测到新的应用数据)时,UE可以使用URSP中的URSP规则来查看该应用数据的特征是否与某一URSP规则中的某一个业务描述符匹配。在一些实现方式中,UE的查看的顺序可以按照URSP规则中规则优先级来决定,即UE基于规则优先级的从高到低的顺序依次查看匹配情况,当匹配到一个URSP规则时,就可以使用URSP规则下的RSD列表进行PDU会话的绑定。因此,在步骤S311中,通常从规则优先级最高的URSP规则开始考察。
在步骤S312中,UE确定考察的URSP规则中的TD是否与应用数据1的特征匹配。
若应用数据1的特征与考察的URSP规则中的TD匹配,则执行步骤S313。若应用数据1的特征与考察的URSP规则中的TD不匹配,则执行步骤S314。
在步骤S313中,UE确定使用考察的URSP规则中的RSD,并执行步骤S315。
在步骤S314中,UE确定考察的URSP规则(或者说当前URSP规则)是否为URSP中规则优先级最低的URSP规则。
若考察的URSP规则不是规则优先级最低的URSP规则,则UE执行步骤S316。若考察的URSP规则是规则优先级最低的URSP规则,则UE执行步骤S317。
在步骤S316中,UE从URSP中选择次优先级的URSP规则作为考察URSP规则,并重新执行步骤S313。
上述次优先级的URSP规则可以理解为是低于最高优先级的URSP规则的下一个优先级的URSP规则。
在步骤S317中,UE确定不使用URSP规则。
在步骤S315中,UE确定考察的URSP规则中的RSD与已经建立的PDU会话参数是否匹配。
若考察的URSP规则中的RSD与已经建立的PDU会话参数不匹配,执行步骤S318。若考察的URSP规则中的RSD与已经建立的PDU会话参数不匹配,执行步骤S319。
在步骤S318中,UE使用考察的URSP规则中优先级最高的RSD建立PDU会话,并执行步骤S320。
在步骤S319中,UE将应用数据1与PDU会话绑定。
需要说明的是,上述PDU会话可以是步骤S319中匹配成功的PDU会话,也可以是步骤S320中成功建立的PDU会话。
在步骤S320中,UE确定PDU会话是否建立成功。
若PDU会话建立成功,则UE执行步骤S319。相反地,若PDU会话未建立成功,则UE执行步骤S321。
在步骤S321中,UE根据拒绝原因值,确定RSD内是否有其他可选内的参数组合。
若RSD内有其他可选的参数组合,则执行步骤S322。相反地,若RSD内没有其他可选的参数组合,则执行步骤S323。
在步骤S322中,UE使用RSD内其他可选的参数组合,建立PDU会话,并执行步骤S320。
在步骤S323中,UE确定当前RSD是否为优先级最低的RSD。
若当前RSD不是优先级最低的RSD,则执行步骤S324。若当前RSD是优先级最低的 RSD,则执行步骤S314。
在步骤S324中,UE使用次优先级的RSD建立PDU会话,并执行步骤S320。
基于上文结合图3介绍的过程可以看出,当有URSP规则与应用数据1的特征匹配时,UE可以先查找当前已经建立的PDU会话是否满足在该匹配的URSP规则下的有效RSD参数,如果有PDU会话满足有效RSD参数(或者说,有PDU会话是使用匹配的URSP规则下的有效RSD参数建立的),则可以应用数据1与该PDU会话绑定。
相反地,如果没有PDU会话满足有效RSD参数,UE可以按照有效RSD中的优先级从高到低的顺序来建立PDU会话,或者说,优先使用优先级高的RSD参数建立PDU会话。需要说明的是,如果有效RSD中的某个参数为一个或多个取值,则UE可以选用其中一个与其他参数一起组合建立PDU会话。
相应地,如果PDU会话建立成功,则UE将该应用数据1绑定到该PDU会话进行传输。相反地,若PDU会话建立不成功,则UE可以使用有效RSD中的其他参数组合,或者使用有效RSD中次优先级的RSD中的参数组合再次尝试PDU会话建立。
通常,上述为应用数据寻找合适的PDU会话的过程可以称之为“评估(evaluation)过程”。通过评估过程可以为应用数据寻找或建立合适的PDU会话,来传输应用数据。在上文介绍的过程中,当匹配的URSP规则中的RSD为“有效RSD”时,UE才能基于该RSD建立PDU会话。
在一些实现方式中,满足以下条件的PDU会话可以称为“有效RSD”。
条件1:如果RSD中有S-NSSAI,S-NSSAI必须属于Allowed NSSAI(非漫游)或者Mapping of Allowed NSSAI(漫游)中的一个。
条件2:如果RSD中有DNN且为本地数据网络(local area data network,LADN)DNN,则UE必须在该LADN对应的有效区域内。
条件3:如果RSD中有接入类型优先级并且设置成了多址接入,则UE必须支持接入流量导向、转换、拆分(access traffic steering,switching,splitting,ATSSS)功能。
条件4:如果RSD中有时间窗和位置标准,则UE匹配应用数据时必须满足时间窗以及位置标准的要求。
相反地,若不满足上述条件中的一条或多条,可以视为无效RSD。在图3所示的流程中可以仅考虑有效的RSD并忽略无效的RSD。
PDU会话的建立过程
图4示出了本申请实施例适用的PDU会话的建立过程,图4所示的方法包括步骤S410至步骤S430。
在步骤S410中,UE向SMF发送PDU会话建立请求。
上述PDU会话建立请求中可以携带PDU会话参数,其中,PDU会话参数可以包括以下信息中的一个或多个:DNN、S-NSSAI、PDU会话类型、SSC模式、PDU会话ID。
在步骤S420中,SMF向UE发送PDU会话建立请求回复。
上述PDU会话建立请求回复用于指示PDU会话是否建立成功。在一些实现方式中,若网络侧拒绝PDU会话建立请求,可以在建立请求回复中携带拒绝原因值。
在步骤S430中,若PDU会话建立请求被拒绝,UE基于URSP规则的RSD参数调整参数组合,并重新发起PDU会话建立过程。
相应地,UE可以基于原因值以及URSP规则的RSD参数调整参数组合,并重新发起PDU会话建立过程。
传统的UE策略规则是由UE的本地PLMN(home PLMN,HPLMN)统一配置的,当UE策略规则被成功配置给UE后,UE策略规则可以适用于各类型的PLMN(例如,访问PLMN(visited PLMN,VPLMN))。然而,这种UE策略规则适用于各个PLMN的方案,可能导致UE策略规则的配置并不灵活。因此,为了提高配置UE策略规则的灵活性,希望UE在接入不同的PLMN后可以使用不同的UE策略规则。
以URSP规则为例,后续可能希望VPLMN也参与URSP规则的制定,在一些实现方式中,VPLMN可以独立确定URSP规则的内容。在另一些实现方式中,VPLMN可以与HPLMN协商确定URSP的内容。在这种场景下,不同的PLMN下UE使用的RSD可能不同。
因此,为了确定RSD适用的PLMN,可以在URSP规则中的RSD内添加一个或多个PLMN ID,来指示该RSD适用的PLMN。在一种实现方式中,上述PLMN ID可以添加在RSD的校验标准中。在另一些实现方式中,上述PLMN ID可以作为专用参数添加在RSD内,以限制使用RSD时UE所接入的PLMN。
这样,若UE当前注册的PLMN(又称“注册PLMN(registered PLMN,RPLMN)”)的PLMN ID与RSD中包括的PLMN ID匹配,则该RSD为有效RSD,该RSD适用于RPLMN。相反地,若RPLMN的PLMN ID与RSD中包括的PLMN ID不匹配,则RSD为无效RSD,该RSD不适用于RPLMN。相应地,UE可以忽略该RSD。
需要说明的是,为了便于描述,下文将上述“RSD适用的PLMN”称为“RSD对应的PLMN”。也就是说,当RSD与PLMN对应时,可以理解为RSD适用于该PLMN,或者,RSD的限制条件(又称“校验标准”)中包含该PLMN的PLMN ID。
上述在RSD的校验标准中添加适用的PLMN ID的方案,可以较大程度的重用现有的 UE行为,也即是说,类似于现有的UE行为(例如,支持R17或之前协议的UE),可以基于RSD中的校验标准,来确定对应的RSD是无效RSD还是有效RSD。
如上文所述,为了指示不同的PLMN适用的UE策略规则,网络设备在为UE配置UE策略规则时,会指示不同的UE策略规则对应的PLMN ID。然而,对于一些传统的UE(例如,支持R17或之前协议的UE)而言,可能只支持HPLMN来配置UE策略规则,也就是说,当UE策略规则中仅包含HPLMN的PLMN ID时,UE不会报错。当UE策略规则中包含除HPLMN之外的其他PLMN(例如,VPLMN)的PLMN ID时,UE会报错。因此,若直接下发带有其他PLMN的PLMN ID的UE策略规则,那么此类UE可能无法再使用UE策略规则。
因此,为了提高UE策略规则的使用成功率,本申请实施例提供了一种无线通信的方法。下文结合图5介绍本申请实施例的方法。图5所示的方法包括步骤S510。
在步骤S510中,UE向网络设备发送第一信息。
其中,第一信息用于指示UE是否支持第一能力,第一能力包括以下的一项或多项:接收非HPLMN对应的UE策略规则;以及接收对应多个PLMN的UE策略规则。
若第一能力包括接收非HPLMN对应的UE策略规则,其中HPLMN又称为“归属PLMN”。通常,UE的全球用户识别卡(universal subscriber identity module,USIM)卡上的国际移动用户识别码(international mobile subscriber identity,IMSI)号中包含的移动国家码(mobile country code,MCC)和移动网络号码(mobile network code,MNC)与HPLMN上的MCC和MNC是一致的。在一些情况下,对于某一UE而言其归属的PLMN只有一个。
相应地,上述非HPLMN可以包含除HPLMN之外的其他PLMN。例如,可以是VPLMN。其中,VPLMN为UE访问的PLMN。VPLMN的MCC、MNC与UE的IMSI的MCC,MNC是不完全相同的。通常,当UE丢失覆盖后,会选择一个VPLMN来接入。
若第一能力包括接收对应多个PLMN的UE策略规则,其中,多个PLMN可以包括HPLMN和/或非HPLMN。
在一些实现方式中,UE可以以隐示的方式通过第一信息来指示是否支持第一能力。也就是说,UE可以通过“发送第一信息”这一动作,来指示是否支持第一能力。例如,当UE发送第一信息时,可以理解为UE支持第一能力。相反地,当UE未发送第一信息,则可以理解为UE不支持第一能力。
在另一些实现方式中,UE可以以显示的方式通过第一信息来指示是否支持第一能力。也就是说,第一信息中可以携带指示(例如,第一信息中可以通过某一比特位的取值)来 指示UE是否支持第一能力。
在本申请实施例中,UE通过向网络设备发送第一信息,来指示UE是否支持第一能力,使得网络设备可以基于第一信息来为UE配置UE策略规则,有利于避免网络设备直接为UE配置非PLMN适用的UE策略规则时,导致UE报错无法使用UE策略规则。
图6示出了本申请另一实施例的无线通信方法的流程图。参见图6,在一些实现方式中,上述网络设备可以是PCF,此时,第一信息由UE通过AMF发送给PCF。在另一些实现方式中,上述网络设备还可以是AMF,相应地,AMF在接收到第一信息后,可以将第一信息转发给PCF。
另外,参见步骤S610,当UE向AMF发送第一信息时,第一信息可以承载于注册请求消息(registration request)中。在一些情况下,注册请求消息中会包含UE策略规则容器(UE policy container),此时,第一信息可以承载于UE策略规则容器中。当然,在本申请实施例中,第一信息还可以是单独传输的信令,本申请实施例对此不作限定。
参见步骤S620,当AMF接收到UE发送的第一信息后,AMF可以将第一信息发送给PCF。在一些实现方式中,第一信息可以承载于UE策略规则控制创建请求(又称“Npcf_UE policy control create request”)中。在一些情况下,UE策略规则控制创建请求中会包含UE策略规则容器,此时,第一信息可以承载于UE策略规则容器中。当然,在本申请实施例中,第一信息还可以是单独传输的信令,本申请实施例对此不作限定。
如上文所述,目前在为UE配置URSP时,为了指示不同的PLMN适用的RSD,会在RSD中添加适用的PLMN的PLMN ID。然而,URSP策略中通常会包含多条URSP规则,并且每条URSP规则中会包含多个RSD。按照上述在RSD中添加使用的PLMN ID的方式,来指示RSD与PLMN ID之间的对应关系,UE需要遍历全部的RSD才能获知某一PLMN使用的RSD有哪些,导致UE的操作较为复杂。
因此,为了降低UE操作的复杂度,本申请实施例还提供了一种无线通信的方法。下文结合图7介绍本申请另一实施例的无线通信方法的流程。图7所示的方法包括步骤S710。
在步骤S710中,网络设备向UE发送第一指示。
上述第一指示用于指示一个或多个PLMN ID与一个或多个UE策略规则(例如,URSP规则)的对应关系。当PLMN ID与UE策略规则具有对应关系时,可以理解为,UE策略规则适用于PLMN ID指示的PLMN。相反地,当PLMN ID与UE策略规则不具有对应关系时,可以理解为,UE策略规则不适用于PLMN ID指示的PLMN。
在本申请实施例中,UE策略规则可以是URSP规则,如此UE可以通过第一指示,来确定PLMN ID与URSP规则的对应关系,避免了UE遍历URSP规则中的全部RSD才能 获知RSD与PLMN ID之间的对应关系,以降低UE操作的复杂度。
在一些实现方式中,上述第一指示可以承载于所述URSP规则所在的URSP中。这样,网络设备在为终端设备配置URSP的过程中,也可以同时向UE发送第一指示。当然,在本申请实施例中,上述第一指示也可以作为单独的信令传输。
下文结合图8以第一指示承载于URSP为例,介绍本申请实施例的无线通信方法。图8所示的方法包括步骤S810至步骤S860。需要说明的是,图8所示的信令发送过程与图2所介绍的信令传输过程类似,区别在于图8所示的方法中UE策略容器中会携带第一指示。为了简洁,图8与图2相似的部分不再赘述。
在步骤S810中,PCF确定是否更新UE策略。
在步骤S820中,PCF向AMF发送通信服务请求。
在一些实现方式中,上信服务请求可以携带UE策略容器,该UE策略容器中包含第一指示。
上述通信服务请求可以通过N1、N2消息传输。因此,通信服务请求又可以表示为“Namf_Communication_N1N2消息发送”。
在步骤S830中,网络侧触发服务请求(network triggered service request),以便网络可以与UE进行通信。
在步骤S840中,AMF向UE发送UE策略。
在一些实现方式中,上述UE策略可以封装在UE策略容器中,该UE策略容器可以是PCF发送给AMF的UE策略容器,相应地,AMF在接收UE策略容器之后,可以直接将UE策略容器透传给UE。其中,UE策略容器中携带第一指示。
在步骤S850中,UE向AMF发送UE策略传输结果。
在步骤S860中,AMF向PCF发送N1消息通知,来告知PCF上述UE策略传输结果。
需要说明的是,在本申请实施例中传输第一信息方法(例如,图5和图6所示的方法)与传输第一指示的方法(例如,图7和图8)可以结合使用,也可以单独使用,本申请实施例对此不作限定。
若上述两个方法结合使用时,UE可以先向网络设备发送第一信息,相应地,网络设备可以基于第一信息来确定是否向UE发送第一指示。即,上述步骤S710包括:若第一信息指示UE支持第一能力,网络设备向UE发送第一指示。若第一信息指示UE不支持第一能力,网络设备不向UE发送第一指示。
其中,若网络设备不向UE发送第一指示,则网络设备可以为UE配置HPLMN对应 的URSP。当然,在本申请实施例中,若网络设备不向UE发送第一指示,网络设备也可以不为UE配置URSP,本申请实施例对此不作限定。
如上文所述,上述传输第一信息的方法还可以单独使用,若第一信息指示UE支持第一能力,网络设备可以为UE配置传统的URSP,即在该URSP中RSD对应的PLMN ID是承载于RSD中的。若第一信息指示UE不支持第一能力,网络设备不向UE发送传统的URSP。
如上文所述,PLMN可以划分为多种类型的PLMN,除了上文介绍的HPLMN和VPLMN之外,还包括注册PLMN(registered PLMN,RPLMN)和等效PLMN(equivalent PLMN,EPLMN)。其中,注册PLMN,可以理解为UE在上次关机或脱网前注册的PLMN。等效PLMN可以理解为与注册PLMN处于同等地位的PLMN,其优先级相同。
对于匹配的URSP规则(下文又称“第一URSP规则”)而言,URSP规则中可能包含适用于等效PLMN的RSD以及适用于注册PLMN的RSD,若UE接入注册PLMN,此时,UE与网络设备之间可能存在使用等效PLMN的RSD建立的PDU会话(下文又称“第一PDU会话”)。目前协议并没有规定在上述场景下,UE能否使用第一PDU会话,导致UE和网络设备的理解可能不一致,无法进行通信。
为了避免上述问题,本申请实施例还提供了一种无线通信方法,以统一UE和网络设备的理解,有利于UE与网络设备之间进行正常通信。下文结合图9介绍本申请实施例的线通信方法的流程。图9所示的无线通信方法包括步骤S910和步骤S920。
在步骤S910中,UE确定匹配的第一URSP规则。
其中,第一URSP规则包括第一RSD,第一RSD对应的PLMN包括UE的注册PLMN的等效PLMN,且UE与网络设备之间有使用第一RSD建立的第一PDU会话。
上述匹配的第一URSP规则可以理解为,第一数据流(例如可以是上文介绍的应用数据的数据流)的特征与第一URSP规则中的TD匹配。
上述第一RSD对应的PLMN包括等效PLMN,可以理解为,第一RSD适用于等效PLMN或者说,第一RSD中包括的PLMN ID为等效PLMN的PLMN ID。其中,PLMN ID在第一RSD中的承载方式已在上文介绍,为了简洁,在此不再赘述。
在步骤S920中,UE确定使用或不使用第一PDU会话。
在一些实现方式中,上述S920可以理解为,UE确定使用或不使用第一PDU会话来传输第一业务的数据流。
在本申请实施例中,UE可以确定使用第一PDU会话,相应地,网络设备也可以确定使用第一PDU会话,有利于统一UE与网络设备的理解,以提高UE与网络设备之间通信 的成功率。
另一方面,若UE确定不使用第一PDU会话,相应地,网络设备也可以确定不使用第一PDU会话,有利于统一UE与网络设备的理解,以提高UE与网络设备之间通信的成功率。
本申请实施例还提供了确定使用第一PDU会话的几种情况,以及不使用第一PDU会话的几种情况,使得第一PDU会话的使用更加合理,下文分别结合第一条件与第二条件进行介绍。
上述步骤S910包括:若满足第一条件,UE确定使用第一PDU会话。
在一些实现方式中,第一条件可以是基于第一URSP规则中是否包括注册PLMN对应的RSD设置的。在另一些实现方式中,第一条件还可以是基于UE和网络设备之间是否有使用注册PLMN对应的RSD建立的PDU会话设置的。下文介绍第一条件的几种实现方式。
第一条件实现方式1,第一条件可以包括第一URSP规则中不包括注册PLMN对应的RSD。
也就是说,第一URSP规则中不包括注册PLMN对应的RSD,且已经使用第一URSP规则中等效的PLMN对应的第一RSD建立了PDU会话(即上述第一PDU会话),此时,UE可以使用第一PDU会话传输第一业务的数据流。
在本申请实施例中,若满足上述第一条件,UE可以确定使用第一PDU会话,以避免UE接入注册PLMN后,UE无法使用URSP规则,导致UE无法与网络设备通信。
第一条件实现方式2,第一条件可以包括第一URSP规则中包括注册PLMN对应的RSD,且UE与网络设备之间未使用注册PLMN对应的RSD建立PDU会话。
也就是说,第一URSP规则中包括注册PLMN对应的RSD以及等效PLMN对应的RSD,且UE与网络设备之间未使用注册PLMN对应的RSD建立PDU会话,但是,UE与网络设备之间有使用等效PLMN对应的RSD建立的PDU会话,此时,UE可以使用第一PDU会话传输第一业务的数据流。
在本申请实施例中,若满足上述第一条件,UE可以确定使用第一PDU会话,以避免基于PLMN对应的RSD重新建立PDU会话,有利于节约建立PDU会话占用的资源。
第一条件实现方式3,第一条件可以包括第一URSP规则中包括注册PLMN对应的RSD,且UE与网络设备之间使用注册PLMN对应的RSD建立PDU会话失败。
也就是说,第一URSP规则中包括注册PLMN对应的RSD以及等效PLMN对应的RSD,且UE与网络设备之间使用注册PLMN对应的RSD建立PDU会话失败,但是,UE 与网络设备之间有使用等效PLMN对应的RSD建立的PDU会话,此时,UE可以使用第一PDU会话传输第一业务的数据流。
在本申请实施例中,若满足上述第一条件,UE可以确定使用第一PDU会话,以避免基于PLMN对应的RSD重新建立PDU会话,有利于节约建立PDU会话占用的资源。
上述步骤S910包括:若满足第二条件,UE确定不使用第一PDU会话。
在一些实现方式中,第二条件可以是基于第一URSP规则中是否包括注册PLMN对应的RSD设置的。在另一些实现方式中,第二条件还可以是基于UE和网络设备之间是否有使用注册PLMN对应的RSD建立的PDU会话设置的。下文介绍第二条件的几种实现方式。
第二条件实现方式1,第二条件可以包括第一URSP规则中包括注册PLMN对应的RSD。
也就是说,第一URSP规则中包括注册PLMN对应的RSD,且已经使用第一URSP规则中等效的PLMN对应的第一RSD建立了PDU会话(即上述第一PDU会话),此时,UE可以不使用第一PDU会话传输第一业务的数据流。
第二条件实现方式2,第二条件可以包括第一URSP规则中包括注册PLMN对应的RSD,且UE与网络设备之间未使用注册PLMN对应的RSD建立PDU会话。
也就是说,第一URSP规则中包括注册PLMN对应的RSD以及等效PLMN对应的RSD,且UE与网络设备之间未使用注册PLMN对应的RSD建立PDU会话,但是,UE与网络设备之间有使用等效PLMN对应的RSD建立的PDU会话,此时,UE可以不使用第一PDU会话传输第一业务的数据流。
第二条件实现方式3,第二条件可以包括第一URSP规则中包括注册PLMN对应的RSD,且UE与网络设备之间有使用注册PLMN对应的RSD建立的PDU会话。
也就是说,第一URSP规则中包括注册PLMN对应的RSD以及等效PLMN对应的RSD,且UE与网络设备之间使用注册PLMN对应的RSD建立了PDU会话,另外,UE与网络设备之间也有使用等效PLMN对应的RSD建立的PDU会话,此时,UE可以不使用第一PDU会话传输第一业务的数据流。
为了便于理解,下文结合图10介绍本申请实施例的无线通信方法。
参见图10,假设URSP中的TD与第一业务匹配,URSP中的每个URSP规则可以携带RSD-1到RSD-3,其中,RSD-1与PLMN-1对应,RSD-2与PLMN-2对应,RSD-3与PLMN-3对应,并且RSD-1到RSD-3的优先级从高到低。
另外,UE的注册PLMN为PLMN-3,且UE接收到的注册回复(Registration Accept) 消息中指示等效PLMN为PLMN-1,即注册PLMN(PLMN-3)的等效PLMN为PLMN-1。并且,UE和网络设备之间有使用RSD-1建立的PDU会话1。
相应地,若满足第一条件,可以将第一业务的数据流绑定在PDU会话1中,而不需要尝试使用该URSP规则下的其他RSD建立新的PDU会话。
若满足第二条件,可以使用RSD-3来建立PDU会话2,并将第一业务的数据流绑定在PDU会话2上进行传输。
需要说明的是,网络设备也可以基于相同的条件确定是否使用第一PDU,判断条件与上文介绍的UE的判断条件相同,为了简洁,在此不再赘述。
本申请实施例还提供一种无线通信方法,以限制在建立PDU会话的过程中,等效PLMN对应的RSD与注册PLMN对应的RSD之间的使用顺序,以统一UE和网络设备的理解。
在本申请实施例中,上述无线通信方法,包括以下两个步骤:UE确定匹配的第一URSP规则,第一URSP规则包括UE的注册PLMN对应的RSD以及注册PLMN的等效PLMN对应的RSD。以及
在使用注册PLMN对应的RSD建立PDU会话失败后,UE使用等效PLMN对应的RSD与网络设备建立PDU会话。
需要说明的是,在本申请实施例中与上文介绍的各种实施例中,功能相同的术语使用的名称相同,请参见上文介绍,为了简洁,在此不再赘述。
