具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施方式使得本公开将更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施方式中。
此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
相关技术中，URSP一般是由运营商在部署PCF时进行预配置，URSP的配置调整不太灵活。
发明人发现，目前的标准中，没有对PCF如何动态选择URSP规则的描述，无法根据实际的网络状况和UE的个体情况实时调整URSP。同一应用，使用不同接入方式或者切片等，业务体验可能也会不同。NWDAF可以通过分析用户的业务使用习惯和不同接入方式、不同切片下的业务体验，辅助PCF配置合理路由策略，即配置更合适用户的URSP规则，从而提升用户体验并合理利用网络资源，然而标准中缺少相应规范。
基于发明人的上述发现，本公开提供了一种路由选择策略配置方法、装置、设备及存储介质，利用NWDAF提供针对UE应用的URSP相关数据分析，辅助PCF对URSP进行动态调整，解决因PCF配置URSP不够灵活而导致UE匹配URSP规则时 效率较低的问题，并提高UE的业务体验和网络资源利用率。
本公开实施例提供的方法可以用于4G(4th Generation Mobile Communication Technology，第四代移动通信技术)、5G(5th Generation Mobile Communication Technology，第五代移动通信技术)、6G(6th Generation Mobile Communication Technology，第六代移动通信技术)甚至进一步演进的通信系统，本公开实施例对此不作限定。下文以本公开实施例应用于5G场景为例，说明本公开实施例提供的技术方案。
在一些实施例中，本公开实施例提供的方案可以应用于5G场景。图1示出了一种5G通信系统的网络架构示意图。
如图1所示，5G通信系统控制面引入了基于服务的架构(Service-Based Architecture，简称：SBA)。在SBA中，每个网元并非一对一(点对点)连接，而是所有网元共享一条通信通道，每个网元都可以与任何网元通信。
本公开实施例中URSP相关数据分析过程，可以通过图1中的NWDAF 101实现。NWDAF 101是提供网络分析的网元，用于实现网络自动化。
NWDAF 101定义了收集什么样的数据，怎样将分析结果反馈到网络等内容。NWDAF 101从整网收集数据，并与AI结合，可在5G网络中实现从数据收集，到数据分析，再到结果反馈的闭环自动化流程。
本公开实施例中的URSP，可以由图1中的PCF 102进行配置。当漫游时，HPLMN中的PCF 102可以更新UE 103中的URSP规则。如TS 24.501所述，UE 103应支持HPLMN中PCF 102对于URSP规则的规定。另外，UE 103也可以被预配置有URSP规则(例如，由运营商进行预配置)。
如果同时存在由PCF 102提供的URSP规则和预配置的URSP规则，则UE 103仅使用PCF 102提供的URSP规则。如果PCF 102未提供URSP规则，并且UE 103在USIM(Universal Subscriber Identity Module，全球用户识别卡)和ME(用户设备)中都配置了预配置的规则，则仅使用在USIM中配置的预配置的URSP规则。
本公开实施例中，PCF 102可以在此基础上，利用NWDAF 101提供针对UE 103应用的URSP相关数据分析，进而，对URSP进行动态调整。
与相关技术中不同，本公开实施例中，不需要在PCF中进行URSP规则的预配置，减少运营商在部署时产生的开销，易于运营商在实际网络中的部署和维护。
UE 103接入5G网络，并与网络建立会话，然后UE 103可以通过AN(Access  Network，接入网络)或RAN(Radio Access Network，无线接入网络)104设备与为UE 103服务的功能网元通信，例如UPF(User Plane Function，用户面功能网元)105、AMF(Access And Mobility Management Function，接入移动性管理功能网元)106等。
此外，图1所示的5G通信系统中还可以包括SMF(Session Management Function，会话管理功能网元)107、AUSF(Authentication Server Function，认证服务器功能网元)108、AF(Application Function，应用功能网元)109、NEF(Network Exposure Function，能力开放功能网元)110、NRF(Network Function Repository Function，网络功能存储功能网元)111、以及NSSF(Network Slice Selection Function，网络切片选择功能网元)112等。
通常，在实际应用中上述各个设备或服务功能之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。
结合上述图1所示的通信系统，下面从通信系统中各个设备交互的角度完整地描述本公开实施例提供的路由选择策略配置方法。
图2示出本公开实施例中一种路由选择策略配置方法流程图，如图2所示，本公开实施例中提供的路由选择策略配置方法包括如下步骤：
S202，NWDAF收集UE在不同情况下使用的URSP规则和URSP规则对应的应用的相关数据；
S204，NWDAF根据UE在不同情况下使用的URSP规则和URSP规则对应的应用的相关数据，分析得到指定时间段内不同网络环境下使用不同URSP的网络性能或用户体验中的至少一个的分析结果；
S206，NWDAF将分析结果发送至PCF；
S208，PCF根据分析结果，配置URSP中的URSP规则及URSP规则的优先级。
在一些实施例中，上述分析结果包括如下数据中的至少一种：
适合预设时长后网络环境的应用的URSP规则预测、用于确定URSP规则的相关数据预测、某段指定时间段网络环境的应用的URSP规则统计、或用于确定URSP规则的相关数据统计。
在一些实施例中，PCF根据所述分析结果，配置URSP中的URSP规则中的一个或多个路由选择组成部分(Route Selection Components，简称：RSC)、及URSP规则的优先级。RSC例如为终端路由选择策略(UE Route Selection Policy，简称：URSP) 的组成部分，其可以进一步包括会话和服务连续模式选择策略(Session and Service Continuity Mode Selection Policy，简称：SSCMSP)、网络切片选择策略(Network Slice Selection Policy，简称：NSSP)、数据网络名称选择策略(DNN Selection Policy)、协议数据单元会话类型策略(PDU Session Type Policy)、非无缝卸载策略(Non-Seamless Offload Policy)、接入类型偏好(Access Type preference)、接近服务层3终端到网络的中继卸载策略(ProSe Layer-3UE-to-Network Relay Offload Policy)、协议数据单元会话对标识(PDU Session Pair ID)、冗余序列号(Redundancy Sequence Number，简称：RSN)。
在一些实施例中，指定时间段内不同网络环境下使用相应URSP规则的网络性能或用户体验中的至少一个的分析结果，是根据所述UE在不同情况下使用的URSP规则中的一个或多个RSC和所述RSC对应的应用的相关数据分析得到的。
作为一个示例，PCF发送至NWDAF的数据订阅请求中可以包括该指定时间段的值。
本公开实施例，可以利用NWDAF对URSP进行灵活部署，帮助运营商合理利用网络资源，提升网络资源利用率。
下面对上述步骤进行详细说明，具体如下所示：
上述步骤中NWDAF是TS 23.501中规定的体系结构的一部分，并使用为5G核心网和OAM指定的机制和接口。
NWDAF可以为不同目的与不同功能网元进行交互，也就是说，上述S202中NWDAF可以通过不同的功能网元获取各类数据，进而可以收集UE在不同情况下使用的URSP规则和URSP规则对应的应用的相关数据。
在一些实施例中，NWDAF收集数据可以包括基于事件订阅的数据收集、从数据存储库中检索信息、或检索有关NF的信息中的至少一种。
作为一个示例，基于事件订阅的数据收集，可以由AMF，SMF，PCF，UDM，AF(直接或通过NEF)或OAM提供。
作为一个示例，从数据存储库中检索信息，UDR通过UDM获取与订阅用户相关的信息。
作为一个示例，检索有关NF的信息，例如，NF相关信息的NRF和切片相关信息的NSSF。
在一些实施例中，S202收集的数据可以包括OAM的全局NF数据，与每个UE 或UE组相关的行为数据(例如，UE可达性)，以及覆盖UE群的预先计算的度量(例如，存在于地理区域中的UE的数量)，每个空间和时间维度(例如，每个区域一段时间)，还可以包括在5GC中的其他NF数据(如NRF)。
作为一个示例，NWDAF可以使用由NF提供的TS 28.532中定义的通用管理服务，用于收集OAM全球NF数据。
作为另一个示例，NWDAF可以使用NF/AF提供的曝光服务，以便检索行为数据和其他非OAM预先计算的指标。
本公开实施例中，将NWDAF的数据分析统计预测功能应用于URSP规则的配置，在NWDAF功能中，引入用户URSP规则使用习惯的分析，对设备改造很小，容易实现。
前文中的URSP可以由多条URSP规则组成，每条规则针对特定的应用，有可能是具体的某个应用，也可能是某些使用相同网络资源的应用，例如都使用某个DNN的全部应用。
每一条URSP规则对应着一种特定的PDU会话，当对应会话存在时，应用使用该会话，当会话不存在时，则建立新的符合要求的会话。
在一些实施例中，NWDAF可以按需向消费者提供分析。上述S204-S206中，NWDAF可以统计分析前文收集的数据，并将分析后预测得到的应用的URSP规则发送至PCF。
TS 23.501中定义的NWDAF为5GC NF，AF和OAM提供分析服务。
这里，分析既可以是过去的统计信息，也可以是未来的预测信息。
NWDAF可用于分析一个或多个网络片。
5GCN(5G Core Network，5G核心网)中可能存在不同的NWDAF实例，每种类别的分析可能具有特殊性。NWDAF实例的容量在存储在NRF中的NWDAF配置文件中描述。
为了支持分析用户发现能够提供某种特定类型分析的NWDAF实例，每个NWDAF实例应提供其在注册NRF时支持的Analytics-ID列表，以及NF配置文件的其他NRF注册元素。
5GS网络功能和OAM决定如何使用NWDAF提供的数据分析来提高网络性能。NWDAF利用现有的基于服务的接口与其他5GC网络功能和OAM进行通信。NWDAF可以使用基于服务的界面将数据分析的结果暴露给任何消费NF。
下面结合附图1，说明上文S204-S206中数据分析和传递的过程。
AF可以通过调用TS 23.502中定义的Nnef_AnalyticsExposure_Fetch服务操作，请求通过NEF接收分析信息。如果分析信息请求由NEF授权，则NEF记录分析触发器和请求者身份的关联。
基于来自AF的请求，NEF通过调用Nnwdaf_AnalyticsInfo_Request服务操作来请求分析信息。NEF可以基于运营商配置对NWDAF的请求施加限制。
作为一个示例，NEF可以对来自Nnwdaf_AnalyticsInfo_Request服务操作的参数或参数值进行限制。
NEF可以使用TS 23.501中定义的NWDAF发现过程选择支持AF请求的分析信息的NWDAF。
本公开实施例中，利用NWDAF的数据分析功能，预测的结果能够辅助PCF了解UE的URSP规则使用习惯，从而提升用户体验。
NWDAF和PCF之间可以互通，如图3所示，NWDAF 301和PCF 302之间互通。
在一些实施例中，NWDAF和PCF之间可以通过Nnwdaf互通。
Nnwdaf使PCF能够订阅切片级别分析数据并得到通知。
作为一个示例，NWDAF通知以下信息：
网络切片实例的标识符；网络切片实例的负载级别信息。
Nnwdaf使PCF能够请求或订阅观测到的服务体验，例如平均观测到的服务MoS(Mean Opinion Score，平均主观意见分)。
Nnwdaf使PCF能够请求或订阅网络性能，并得到通知。
Nnwdaf使PCF能够请求或订阅UE相关分析，并得到通知。
如图3所示，NWDAF 301还可以与NSSF(Network Slice Selection Function，网络切片选择功能网元)303、AMF(Access And Mobility Management Function，接入移动性管理功能网元)304、SMF(Session Management Function，会话管理功能网元)305、NEF(Network Exposure Function，网络功能开放功能网元)306、UDM(Unified Data Management，统一数据管理网元)307互通。
此外，NWDAF 301还可以与AF、OAM、CEF互通，图3未示出。
在一些实施例中，前文S208中的URSP可以是一张包含一个或多个URSP规则的列表。
URSP的每个URSP规则由该规则的规则优先级，流量描述符和路由选择描述符 (Route Selection Descriptor，简称：RSD)列表组成。前文S208中配置URSP规则的优先级，便可以是这里的优先级。
每个规则的优先级各不相同，且各个规则按照优先级从高到低排序。优先级决定了UE使用URSP规则的顺序。
流量描述符由一个或多个组件组成，这些组件可以包括应用描述符、IP描述符(目的IP)、域描述符(目的FQDN)、非IP描述符和连接能力中的一个或多个。其中流量描述符供UE使用进行应用匹配。
RSD列表包含一个或多个RSD，每个RSD由各自的RSD优先级，路由选择组件和路由选择校验标准组成。
RSD优先级决定了使用RSD的顺序，当优先级高的RSD无法使用时，才使用其它RSD。
路由选择组件描述了应用可以使用的各种网络资源，它由一个或多个组件组成，包括SSC(Session and Service Continuity，会话和服务连续性)模式选择、网络切片选择、DNN选择、PDU会话类型选择、有缝卸载指示、接入类型优先级。
下面对各组件的含义进行说明：
SSC模式选择策略(SSCMSP)：UE用来将匹配的应用与SSC模式相关联；
网络切片选择策略(NSSP)：UE用来将匹配的应用与S-NSSAI相关联；
DNN选择策略：UE用来将匹配的应用与DNN相关联；
PDU会话类型策略：UE用来将匹配的应用与PDU会话类型相匹配。
有缝卸载策略：UE用来决定匹配的应用应该有缝地卸载到(例如PDU会话之外的)非3GPP接入；
接入类型优先级：如果UE需要为匹配的应用建立一个PDU会话，它将表明优先的接入类型(3GPP或非3GPP或多接入)。
路由选择校验标准描述了对应的生效条件。它包括时间窗口和位置标准。如果当前时间不在时间窗口内或者UE位置不匹配位置标准，则认为RSD无效。
本公开实施例是网络智能化在URSP策略中的应用，为UE提供专属的数据分析，令PCF中的URSP规则能够根据UE情况和网络状态动态配置，使其能够更灵活的适用于不同的场景，提升URSP匹配效率和网络资源利用率。
针对目前3GPP标准中，核心网决策网元PCF无法针对用户使用习惯及网络状态等动态配置URSP规则，从而导致UE业务体验不佳、网络资源利用不合理等问题。
本公开实施例提出利用NWDAF的数据统计预测分析功能，从5GC NF、AF、OAM等网元收集和UE应用的相关数据，并进行大数据分析，得到UE在不同时间地点的URSP规则使用习惯和不同接入情况及网络资源下UE使用URSP的用户体验等统计和预测结果。PCF参考NWDAF提供的结果动态配置URSP规则和优先级，从而提升UE的业务体验、URSP规则匹配的效率、以及网络资源优化效果等。
图4示出了一种路由选择策略URSP配置方法流程示意图，如图4所示，该方法可以包括如下步骤。
S402，UE提供PSI(Public Service Identify，公共业务标识)，使PCF确定UE是否需要请求新的URSP。
S404，请求建立或更新UE的URSP策略连接。
S406，请求为UE的URSP提供相关的数据分析，并提供UE ID等信息。
这里，PCF请求NWDAF提供UE的URSP相关数据分析时，可以同时提供NWDAF返回订阅通知的触发条件，可以包括周期性返回订阅信息、超过或/和低于某个门限值返回订阅信息等，以便当UE情况或网络状况发生改变时，PCF能够及时被通知，从而进行URSP的动态配置。
S408，NWDAF从相关网元收集数据，对UE使用的URSP规则情况和服务体验进行统计和预测。
这里，NWDAF从各个网元收集UE的URSP相关信息，例如，应用ID、切片信息、DNN、应用使用时间、地点、用户业务体验等。通过数据分析，对UE在特定时间、特定地点使用的URSP规则(应用ID、接入的切片、接入DNN等)以及在不同接入方式下使用不同规则的用户体验进行统计和预测。
S410，向PCF提供分析结果。
这里，NWDAF将统计和预测结果发给PCF，如果S406中PCF订阅了UE的URSP相关数据分析，NWDAF可以根据订阅信息中的触发条件主动触发流程，发送更新的统计和预测结果给PCF。
在一些实施例中，在UE情况不同或网络环境不同中的至少一种的情况下，可以将所述分析结果发送至策略控制功能网元PCF。
在网络性能参数不符合预设性能条件或用户体验值低于预设报告阈值中的至少一种的情况下，网络环境不同。
在一些实施例中，在网络性能参数不符合预设性能条件或用户体验值低于预设报 告阈值中的至少一种情况下，将所述分析结果发送至策略控制功能网元PCF。
作为一个示例，当UE的情况或网络状态发生改变导致NWDAF分析结果更新时，NWDAF可以主动触发流程，发送更新的统计和预测结果给PCF。
需要说明的是，分析结果可以是指定时间段内不同网络环境下使用不同URSP的网络性能和/或用户体验的分析结果。
在一些实施例中，分析结果可以包括如下数据中的至少一种：
适合预设时长后网络环境的应用的URSP规则预测、用于确定URSP规则的相关数据预测、某段指定时间段网络环境的应用的URSP规则统计、或用于确定URSP规则的相关数据统计。
S412，PCF根据分析统计和预测结果配置URSP内容及优先级。
这里，决策网元PCF参考NWDAF提供的统计和预测结果对URSP规则的内容和优先级进行灵活配置。
S414，将UE的URSP信息传给AMF。
S416，将UE的URSP下发给UE。
作为一个示例，上述步骤中NWDAF分析的输入和输出可以如表1所示：
表1
Figure PCTCN2022135737-appb-000001
Figure PCTCN2022135737-appb-000002
需要说明的是，如果PCF向NWDAF订阅了URSP数据分析服务，则上述步骤也可能从S408开始，可由NWDAF触发。
在一个实施例中，当用户进入室内使用语音业务时，根据大数据分析，可以调整相应的URSP策略，利用Wifi来补充室内移动信号覆盖，实现VoWifi与VoLTE/VoNR的无缝切换。

在一些实施例中，上述方法还可以包括：
接收PCF发送的数据订阅请求，数据订阅请求用于指示NWDAF将预测和/或统计得到的应用的URSP规则、或者用于确定URSP规则的相关数据中的至少一种发送至策略控制功能网元PCF。
