本申请主张在2022年03月29日在中国提交的中国专利申请No.202210323989.4及在2022年05月06日在中国提交的中国专利申请No.202210488188.3的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种策略控制方法、设备及存储介质。
背景技术
策略控制功能(Policy Control Function，PCF)在用户设备(User Equipment，UE)的会话建立时，下发PCC规则(PCC rules；PCC：策略与计费控制，Policy and Charging Control)。当下一代无线接入网(NG-RAN；NG：下一代，Next Generation；RAN：无线接入网，Radio Access Network)判断保证流比特率(Guaranteed Flow Bit Rate，GFBR)、分组包延迟预算(Packet Delay Budget，PDB)、分组包错误率(Packet Error Rate，PER)不能得到满足时，NG-RAN会向会话管理功能(Session Management Function，SMF)发送"GFBR无法再保证(GFBR can no longer be guaranteed)"通知。NG-RAN在发送通知前会检查当前能满足的GFBR、PDB、PER是否能够匹配上备选QoS配置文件(Alternative QoS Profile；QoS：服务质量，Quality of Service)列表中的某一个(按照每个Alternative QoS Profile的优先级逐个匹配)。如果有匹配上的Alternative QoS Profile，NG-RAN会在发送给SMF的通知中携带该匹配上的Alternative QoS Profile的引用(只发送第一个匹配上的，即：最高优先级的Alternative QoS Profile)。

一种计算机可读存储介质，其中，所述计算机可读存储介质存储有计算 机程序，所述计算机程序被处理器执行时实现上述第一网络功能侧、第二网络功能侧或第三网络功能侧的服务质量调整方法。
本公开有益效果如下：
本公开实施例提供的技术方案中，由于第一网络功能根据第一参数决定第一策略，克服了相关方案仅考虑了单流的服务质量调整情况的不足。
进一步的，由于第一网络功能根据第一参数决定策略和计费控制规则，而第一参数包括相关流的参数，因此不是对单独调整单一的服务质量流，克服了相关方案仅考虑了单流的服务质量调整情况的不足。
进一步的，由于引入关联QFI组的概念，第一网络功能在收到第三网络功能经第二网络功能提供的服务质量调整请求后，调整的对象是关联服务质量流组中各服务质量流的参数，而不是对单独调整单一的服务质量流，组内的服务质量流不会单独变化，因此克服了相关方案仅考虑了单流的服务质量调整情况的不足。
进一步的，在触感通信及多媒体增强通信中，往往会有多种业务流类型，如视频、音频、触感、动觉信号等，这些业务流不是单独存在，而需要互相配合才能给用户完整良好的体验。在当前方案中，如果NG-RAN无法满足某一个业务流的服务质量要求，则会对其进行服务质量降级。在多媒体及触感通信中，如果某一业务质量下降过大，可能会影响整个业务。比如动觉信号传输正常，但是视频流降级严重，则可能出现画面过于模糊，难以凭借双眼准确判断出该如何操作设备的情况。因此，通过本公开实施例提供的技术方案，能够在服务质量调整中综合考虑同一业务其他QoS flow的情况后来进行业务调整，从而能够保证用户的整体业务体验。

具体实施方式
发明人在发明过程中注意到：
相关方案仅考虑了单流的服务质量调整情况。在触感通信及多媒体增强通信中，往往会有多种业务流类型，如视频、音频、触感、动觉信号等，这些业务流不是单独存在，而需要互相配合才能给用户完整良好的体验。在当前方案中，如果NG-RAN无法满足某一个业务流的服务质量要求，则会对其进行服务质量降级。在多媒体及触感通信中，如果某一业务质量下降过大，可能会影响整个业务。比如动觉信号传输正常，但是视频流降级严重，则可能出现画面过于模糊，难以凭借双眼准确判断出该如何操作设备的情况。因此，在服务质量调整中需要综合考虑同一业务其他服务质量流(QoS flow)的情况来进行业务调整，这样才能保证用户的整体业务体验。
本公开实施例中，相关流可以为：具有一定相关性的流(Flow)。这里的相关性可以根据实际的情况进行相应的设定。例如，若干个流的QoS调整存在一定的关联，彼此QoS的变化是不独立的，也即一个流的QoS变化了可能会影响其他的相关流的QoS变化。本文中有时候也将相关流称为关联流，将相关性称为关联性或相关关系或关联关系等。
基于此，本公开实施例提供的技术方案针对触感及多媒体增强通信这类需要多流协同的业务，给出了不同类型服务质量流的协同服务质量调整方案， 保证多业务流之间的服务质量可以保证整体业务效果，不会出现某一个QoS flow被降级严重以至于无法保证整体用户体验的情况。
下面结合附图对本公开的具体实施方式进行说明。
在说明过程中，将分别从第一网络功能、第二网络功能与第一实体侧的实施进行说明，然后还将给出它们配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着它们必须配合实施、或者必须单独实施，实际上，当它们分开实施时，其也各自解决自身一侧的问题，而它们结合使用时，会获得更好的技术效果。
为便于理解，具体实例中将主要以以下网络功能的实施来进行说明：
策略控制功能(Policy Control Function，PCF)：第一网络功能，也可以是网络能力开放功能(Network Exposure Function，NEF)、无线接入网(Radio Access Network，RAN)、基站；
应用功能(Application Function，AF)：第二网络功能，也可以是网络开放功能、第三方服务器、会话管理功能；
PCF，AMF，SMF，或AF：第三网络功能；
无线接入网络(Radio Access Network，RAN)：第一实体，也可以是RAN(Radio access network)，用户设备(User Equipment，UE)，基站，AMF；
SMF、或UPF：第二实体。
图1为第一网络功能侧的策略控制方法实施流程示意图，如图所示，可以包括：
步骤101、第一网络功能根据第一参数，决定第一策略。
实施中的决定可以理解为determine，在具体实施时，可以分为以下两种情况，一种可以为：目前还没有策略和计费控制规则，第一网络功能根据第一参数生成(generate、create)了策略和计费控制规则；另一种情况为：目前已有策略和计费控制规则，第一网络功能根据第一参数更新(update)了策略和计费控制规则。
该方式用以实现多流协同的传输，例如同时到达终端/应用服务器(server)/RAN，或保持时延差不变到达终端/应用server/RAN，保证在规定时延差内到达终端/应用server/RAN。
实施中，所述第一策略用于多流协同传输或多流协同处理。
多流协同传输或多流协同处理用于说明策略名称。

指示流关联关系的信息可以是流关联关系。
指示时延差的信息可以是延迟差(delay difference)，可以通过以下方式获得：一、第五代移动通信(the 5th Generation，5G)系统通过QoS监控(QoS monitoring)的机制测量端到端的时延，获得各流的单独传输时延，并上报给PCF，由PCF计算得出目标流的时延差；二、针对下行报文，一个或者多个应用服务器或者用户面功能在发送报文时，在报文头(基于IPv6的源路由技术(Segment Routing IPv6，SRv6)扩展头或者网际互联协议(Internet Protocol，IP)扩展头或者GTP-用户面(GPRS Tunnelling Protocol for User Plane，GTP-U；GTP：GPRS隧道协议，GPRS Tunnelling Protocol；GPRS：通用分组无线业务，General Packet Radio Service)扩展头)添加标签或者时间戳。终端收到报文后，通过读取时间戳，或者识别两个流的标签，可计算出两个流之间的 传输时延差值。由终端报给5G核心网。对于上行报文，终端在发送报文时，在报文头(SRv6扩展头或者IP扩展头)添加标签和时间戳。用户面功能收到报文后，通过读取时间戳，或者识别两个流的标签，可计算出两个流之间的传输时延差值。UPF或者RAN可以根据标签或者时间戳实现报文缓存，以实现报文对齐。
具体实施中，所述用于指示流关联关系的信息，用于指示该业务流属于多模态流，和/或该业务流是多模态流中的流，和/或该业务流是多流组中的流。
具体实施中，所述时延差用于指示多流之间的端到端时延差，或者多流之间的空口时延差，或者多流之间的网络时延差。
具体的，用于指示时延差的信息可以是时延差。
实施中，所述第一策略是第一网络功能根据第二网络功能提供的第一参数决定的。
具体的，决定可以理解为determine，在具体实施时，可以分为以下两种情况，一种可以为：目前还没有策略和计费控制规则，第一网络功能根据第一参数生成(generate、create)了策略和计费控制规则；另一种情况为：目前已有策略和计费控制规则，第一网络功能根据第一参数更新(update)了策略和计费控制规则。
实施中，所述第一参数包括以下一项或多项：
应用需求，策略需求，终端标识，终端地址，应用功能标识符，流描述，服务质量需求，候选服务质量Alternative QoS，流时延需求，流时延，多流间的时延差，业务流速率，最大数据突发量(Maximum Data Burst Volume)，关联ID，带宽，延迟(Delay)差。
关联ID可以是相关ID(correlation ID)、多通道流量相关ID(multi-modality flow correlation ID)、多通道交通流量相关ID(multi-modality traffic flow correlation ID)、流量相关ID(flow correlation ID)。
所述第一网络功能可能是以下一项或多项：

实施中，所述多流协同传输或多流协同处理，用于支持多个业务流同时 到达终端和/或应用服务器和/或基站和/或UPF，或保持时延差不变的到达终端和/或应用服务器和/或基站和/或UPF，或保证在规定时延差内到达终端或应用服务器或基站和/或UPF。
实施中，所述第二网络功能是以下一个或者多个网络功能的组合：应用功能、网络开放功能、第三方服务器、会话管理功能。
当时指示延差的信息不满足流时延需求时，第一网络功能发送第一通知给第四网络功能，第四网络功能做应用层调整。
实施中，当时指示延差的信息不满足流时延需求时，第一网络功能做第一规则调整。
实施中，第一规则是PCC rules。
具体的，这里的不满足，可以是指示延差的信息大于流时延需求，也可以是关联流中的某一个流不满足时延要求，即过大或者过小。当指示延差的信息小于流时延需求时，PCF为关联流中的每个流调整PCC规则(PCC rules；PCC：策略与计费控制，Policy and Charging Control)，例如使用可选QoS配置文件(alternative QoS profile)，或者调整QoS参数(PDB，优先级，Priority level)。对于时延过大的流，PCF调整QoS参数，如使用更小的端对端(End to End，E2E)PDB或是更高优先级(High Priority Level)；对于时延过小的流，PCF调整QoS参数，可以将QoS参数中的E2E PDB调大，或是使用更低的优先级(Low Priority Level)。
实施中，第四网络功能至少是以下网络功能之一：应用功能AF、边缘应用、边缘应用服务器、边缘应用平台、网络能力开放功能NEF。
实施中，第一通知至少包含以下信息之一：
流时延、时延差、delay difference、流间时延差、时延差策略。
具体的，这个调整，可以是适应(adaptation)，可以是适配，或者可以是策略调整。
本公开实施例中，第一网络功能还可以接收第一实体的第二通知，更新第一策略。这里，第二通知可以是用于指示第一流的以下一项或多项：
(1)当前无法保障第一流的传输；
(2)当前无法保障第一流的QoS；
(3)当前支持的第一流的最大保证比特速率(Guaranteed Bit Rate，GBR)；
(4)当前支持的第一流的最大非保证比特速率Non-GBR；
(5)当前支持的第一流的时延；
(6)当前支持的第一流的带宽。
具体的，第一流可以是一个或多个流。
这样，第一网络功能可以根据第二通知，更新第一策略。本公开实施例中，所述更新第一策略，可以指对策略进行调整，如更新(update)、调整(adjust)等。
例如，PCF接收RAN发送的第二通知(notification)，然后根据第二通知更新第一策略。
具体的，更新第一策略，可以包括以下至少一项：
(1)降低或升高全部相关流的QoS优先级；
(2)降低或升高部分相关流的QoS优先级；
(3)释放全部相关流；
(4)释放部分相关流；

(6)解除部分相关流的相关性。
这里，所述的全部相关流，可以是具有相关性的全部流，例如，第一流和第一流的所有相关流。部分相关流，可以是具有相关性的全部流中的部分流。
本公开实施例中，在对多个流更新所述第一策略时，所述多个流可能有多种更新方案，以升级/降级为例，如表1所示，存在着多种组合，表1中的升级和降级，可能是升一级，也可能是升多级。

表1

实施中，所述第二实体包括以下一项或多项：SMF、UPF。
下面为第一网络功能侧的服务质量调整方法实施，可以包括：
第一网络功能根据第一参数，决定策略和计费控制规则；其中，所述第一参数包括相关流的参数。
具体的，第一参数可以由其他网元如第二网络功能直接或间接发送，也 可以由其他设备(例如网管系统)直接配置给第一网络功能，或可以通过其他可行的方式将第一参数预配置给第一网络功能。
实施中的决定可以理解为determine，在具体实施时，可以分为以下两种情况，一种可以为：目前还没有策略和计费控制规则，第一网络功能根据第一参数生成(generate、create)了策略和计费控制规则；另一种情况为：目前已有策略和计费控制规则，第一网络功能根据第一参数更新(update)了策略和计费控制规则。
第一参数包括相关流的参数至少可以有以下两种实施方式：
第一种：第一参数除了包含相关流的参数还可以包括其他参数，其他参数可以用于供第一网络功能决定策略和计费控制规则，也可以不用于决定策略和计费控制规则。
第二种：第一参数仅包括相关流的参数，也即第一参数与相关流的参数是等同的概念。
相关流可以为：具有一定相关性的流(Flow)。这里的相关性可以根据实际的情况进行相应的设定。例如，若干个流的QoS调整存在一定的关联，彼此QoS的变化是不独立的，也即一个流的QoS变化了可能会影响其他的相关流的QoS变化。本文中有时候也将相关流称为关联流，将相关性称为关联性或相关关系或关联关系等。具体例如，一个音频流的时延指标设定需要考虑对应的视频流的时延指标，两者相差不能大于一个固定值，从而保证用户的业务体验。
不难理解的是，第一网络功能决定、生成或更新得到的策略和计费控制规则PCC规则(PCC rule；PCC：策略与计费控制，Policy and Charging Control)是为了后续能够用于进行某一个或多个指定流的调整。因为在决定、生成或更新的策略和计费控制规则PCC rule的过程中参考了相关流的参数，所以根据得到的PCC rule来进行该一个或多个指定流的调整，可以充分考虑到与该一个或多个指定流相关的流的一个情况(例如可以考虑相关流的QoS)，从而保证用户的整体业务体验。
实施中，所述第一参数还包括以下参数之一或者其组合：
终端地址、应用功能标识符、流描述、服务质量参考、候选服务质量。
实施中，所述相关流为属于同一个组的流。
具体的，相关的流一定属于同一组，但同一组中的流也可能都相关，也可能存在与指定的流不相关的流。但方案中第一参数中包含的相关流的参数是在同一组中具有一定相关性的流的参数信息。
实施中，所述相关流的参数包括相关服务质量流ID和/或候选服务质量。
具体的，例如，一组中流1、流2、流3、流4是相关的，那么相关流的参数可以包括相关服务质量流ID，也即QFI1(QoS flow ID 1，QFI1)、QFI2、QFI3、QFI4。进而第一网络功能就能够根据这些ID获知流之间的关联关系。
第一候选服务质量的一种可选的实施方式为：相关流之间的调整限制。例如，流1和流2之间的时延不能超过xx。第一候选服务质量可以描述所有相关流之间的调整限制，也可以描述相关流中部分流之间的调整限制。
实施时候选服务质量可以属于相关流参数中的一种参数，也可以属于第一参数中的一种参数。
当然，方案中的“候选服务质量”的这一名称仅仅是本公开中所举的一个实施例，在实际情况下，本领域技术人员也可以用其他的称呼命名这一内容，例如，称为“第一信息”，也即所述相关流的参数包括相关服务质量流ID和/或第一信息。
实施中，所述策略和计费控制规则中包括：相关流的服务质量和候选服务质量。
具体的，例如，若流1、流2、流3、流4相关，则PCC rule中包含流1的候选服务质量Alternative QoS，以及流2、流3、流4的服务质量QoS。
实施中，所述策略和计费控制规则中包括：相关流的服务质量和候选服务质量的关联关系。
具体的，进一步地，PCC rule除了可以包含相关流的服务质量和候选服务质量，还可以进步包含二者之间的关联关系。例如是相关流的服务质量和候选服务质量的对应关系。

具体可以新增表(table)，表明QFI之间的关系，当进行一个流的服务质量调整的时候，可以考虑AF请求、网络状态、关联QFI当前的服务质量状态，然后做出判断，该服务质量流是升级/降级/维持现状。
这里的第一实体可以为RAN。NG-RAN在资源无法保证时，服务质量调整需考虑当前关联QFI的情况，也即PCF发送的PCC rule中相关流的QoS以及alternative QoS(或二者的关联关系)，然后选择合适的alternative QoS(候选QoS)来进行资源升降级。

具体实施可以参见第一网络功能侧、第二网络功能侧或第一实体侧的服务质量调整方法的实施。
综上所述，本公开实施例提供的技术方案中，引入关联QFI组的概念，组内的服务质量流不会单独变化，需要当前组的情况然后进行服务质量调整。
通过在PCF中新增table，表明QFI之间的关系，当PCF进行一个流的服务质量调整的时候，需要考虑AF请求，网络状态，关联QFI当前的服务质量状态，然后做出判断，该服务质量流是升级/降级/维持现状。
NG-RAN在资源无法保证时，服务质量调整需考虑当前关联QFI的情况，然后选择合适的alternative QoS来进行资源升降级。
相关方案仅考虑了单流的服务质量调整情况。在触感通信及多媒体增强通信中，往往会有多种业务流类型，如视频、音频、触感、动觉信号等，这些业务流不是单独存在，而需要互相配合才能给用户完整良好的体验。在当前方案中，如果NG-RAN无法满足某一个业务流的服务质量要求，则会对其进行服务质量降级。在多媒体及触感通信中，如果某一业务质量下降过大，可能会影响整个业务。比如动觉信号传输正常，但是视频流降级严重，则可能出现画面过于模糊，难以凭借双眼准确判断出该如何操作设备的情况。因此，在服务质量调整中需要综合考虑同一业务其他QoS flow的情况来进行业务调整，这样才能保证用户的整体业务体验。
