具体实施方式
本申请实施例提供一种服务质量的处理方法和装置，其中，方法和装置是基于相同或相似技术构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
以下，首先对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、本申请实施例中涉及的会话管理网元，可以为通信系统架构中的SMF网元，用于负责隧道维护、IP地址分配和管理、UP功能选择、策略实施和QoS中的控制、计费数据采集、漫游等。
本申请实施例的执行主体可以为会话管理网元，或者会话管理网元对应的芯片，并且本申请实施例中的该会话管理网元可以为物理上的实体网元，也可以是虚拟的网元，本申请对该会话管理网元的具体形态不做限定。
2)、本申请实施例中涉及的接入网设备，可以为终端设备提供接入的设备，包含无线接入网(Radio Access Network，RAN)设备和AN设备。RAN设备主要是3GPP网络无线网络设备，AN可以是non-3GPP定义的接入网设备。RAN设备用于负责空口侧的无线资源管理、服务质量(quality of service，QoS)管理、数据压缩和加密等功能。该RAN设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如， 在第五代(5th generation，5G)系统中，称为RAN或者gNB(5G NodeB)；在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)；在第三代(3rd generation，3G)系统中，称为节点B(Node B)等。本申请对接入网设备的具体形态不做限定。
3)、本申请实施例中涉及的策略控制网元，可以为通信系统架构中的PCF网元，用于提供策略规则给网络实体实施，可支持统一的策略框架去管理网络行为，访问统一数据存储的订阅信息。例如，在本申请实施例中的策略控制网元用于向会话管理网元下发规则，并且还用于管理业务流，即修改或删除业务流的服务质量参数。
本申请实施例的执行主体可以为策略控制网元，或者策略控制网元对应的芯片，并且本申请中的该策略控制网元可以为物理上的实体网元，也可以是虚拟的网元，本申请对策略控制网元的具体形态不做限定。
4)、本申请实施例中涉及的服务质量(Quality of Service，QoS)，通常可以表示服务能够满足规定和潜在需求的特征和特性的总和，即服务工作可以满足被服务者需求的程度。
在本申请方案中，服务质量可以表示为一种有效管理网络资源的技术，针对各种业务的不同需求，可以为其提供端到端的服务质量保证。具体的，一个网络可以利用各种基础技术，为指定的网络通信提供更好的服务能力，从而可以避免网络延迟和阻塞等问题，而且针对容量有限的网络，特别是流多媒体应用，例如网络电话(Voice over Internet Protocol，VoIP)和交互式网络电视(Interactive Personality TV，IPTV)等，由于这种媒体应用需要有固定的传输率，并且对延时也比较敏感，因此，保证服务质量是十分重要的。
总之，QoS可以为指对网络用户体验到的服务的整体性能衡量，例如可以通过测量QoS分组丢包率，比特率，吞吐量，传输时延，可用性，抖动等服务的相关方面，以衡量网络的服务质量。
5)、本申请实施例中涉及的业务流的服务质量参数，可以为业务流的服务质量参数/属性信息，即通过一系列可度量的服务质量参数/属性来衡量业务流的服务质量，网络可以根据服务质量参数/属性信息，配置相应的业务流，从而使得业务流为指定的网络通信提供更好的服务质量。具体的，服务质量参数/属性可以包括但不限于包括：优先等级、包时延预算、最大数据突发量、服务质量的标识、通知控制信息，其中，服务质量的标识可以为5QI。
6)、本申请实施例中涉及的策略与计费控制规则(Policy and Charging Control Rule，PCC Rule)，可以表示为一系列相关信息与一系列相关操作的集合，相关信息主要可以包括该三类信息：1)、服务数据流检查信息，2)、策略控制信息、3)、计费相关信息。
PCC规则可以用于检测业务数据流(Service Data Flow，SDF)，以及对业务数据流进行策略控制和计费的规则集合。因此，PCC规则的作用具体可以包括但不限于检测数据包(如IP包)属于哪个业务数据流、标识业务数据流提供策略控制等。
另外，PCC规则通常可以分为动态PCC规则和静态预定义PCC规则，针对动态的PCC规则，由策略与计费规则功能(Policy and Charging Rules Function，PCRF)单元的接口Gx将该PCC规则下发给策略和计费执行功能(Policy and Charging Enforcement Function，PCEF)单元，然后由PCEF单元来执行，在该过程中，PCRF单元不仅可以建立该类规则，还可以修改、删除这类规则；需要注意的是，在5G通信中由策略控制(policy control function，PCF)单元通过N7接口将PCC规则下发给会话管理SMF单元，然后由SMF单元执行。针对静态预定义的PCC规则，由PCEF单元预配，并且PCRF单元只能引用这类规则。
需要注意的是，本申请中由于PCC规则是SDF粒度的，而5G的QoS模型是QoS flow粒度的，即接入设备RAN是基于QoS flow粒度来进行调度的，因此，需要将业务数据流SDF映射到QoS flow上，以实现QoS的控制或处理。
7)、本申请实施例中涉及的绑定处理，可以为将业务数据流(即通过SDF模板在PCC规则中定义)与作为传输业务数据流的业务流相关联的过程。绑定机制具体的可以包括三个步骤：第一步骤：会话绑定，将应用功能会话(AF Session)和PDU会话进行一一对应；第二步骤：由PCF网元对PCC规则进行授权，为PCC规则分配QoS参数；Step3：由SMF网元将PCC规则与业务流QoS flow进行绑定，使得该PCC规则与QoS flow对应，当PCF网元提供PCC规则时，SMF网元应评估是否存在QoS参数与绑定的PCC规则的参数相同的QoS flow。如果不存在此类QoS flow，SMF网元使用PCC规则中的参数导出新QoS flow的QoS参数，将PCC规则绑定到该QoS flow。当然，还有一些特殊情况需要SMF网元将PCC规则绑定至默认QoS flow(the QoS Flow associated with the default QoS rule)或者单独的QoS flow，例如当PCC规则中存在Alternative QoS parameter Set(s)时。需要额外说明的是，本申请中的业务流也可以理解为服务质量流，或者服务质量流中可以包括一个或者多个业务流，本申请并不限定。
另外，PCC规则与PDU会话内的QoS流进行绑定关联时，可以使用以下参数/属性执行：5QI、分配和预留优先级(Allocation and Retention Priority，ARP)、服务质量通知控制(QoS Notification Control，QNC)、优先级Priority Level、平均窗口Averaging Window、最大数据突发量Maximum Data Burst Volume。需要的注意的是，具备上述参数/属性的不同PCC规则可以绑定至不同的QoS flow。
本申请实施例提供的一种服务质量的处理方法可以适用于基于参考点的非漫游5G系统架构，如图1A和1B所示，展示了两种基于参考点的非漫游5G系统架构。另外，本申请实施例提供的一种服务质量的处理方法还可以适用于基于服务化的5G系统架构，本申请对此不做具体限定。
下面对5G系统架构中具体的网元/模块进行详细介绍。
该5G系统主要包括：网络切片选择功能(Network Slice Selection Function，NSSF)网元、网络开放功能(Network Exposure Function，NEF)网元、网络存储功能(NF Repository Function，NRF)网元、策略控制功能(Policy Control Function，PCF)网元、统一数据管理(Unified Data Management，UDM)网元、应用功能(Application Function，AF)网元、鉴权服务功能(Authentication Server Function，AUSF)网元、接入和移动性管理功能(Access and Mobility Management Function，AMF)网元、会话管理功能(Session Management Function，SMF)网元，终端(User Equipment，UE)设备、接入网((Radio)Access Network，(R)AN)设备、用户面功能(User plane Function，UPF)网元、数据网络(Data Network，DN)。为了便于描述，以策略控制功能为例，策略控制功能网元可以简称为PCF网元，其他网元同理，不再赘述。
参考图1A所示，Nnnsf、Nnef、Nausf、Nnrf、Namf、Npcf、Nsmf、Nudm、Naf分别是NSSF、NEF、AUSF、NRF、SMF、PCF、SMF、UDM、AF展现的基于服务的接口；参考图1B所示，N1是UE和AMF之间的参考点，N2是(R)AN和所述AMF之间的参考点，N3是(R)AN和所述UPF之间的参考点，N4是SMF和UPF之间的参考点，N6是UPF和所述DN之间的参考点，依次类推，N7、N8等均表示为对应连接的网元之间的 参考点，此处不再具体赘述。
PCF网元：用于提供策略规则给网络实体实施，可支持统一的策略框架去管理网络行为，访问统一数据存储(UDR)的订阅信息。
UDM网元：用于统一管理用户数据，存储鉴权证书/鉴权参数，以及存储和管理5G系统的永久性用户ID(或UE的永久性标识(SUbscription Permanent Identifier，SUPI))，用户的服务网元注册管理(比如当前为终端提供业务的AMF、SMF等)。
AF网元：为应用层的各种服务，可为运营商内部的应用、还可为第三方的AF网元(如视频服务器、游戏服务器)，如果是运营商内部的AF，与其他NF在一个可信域内，可与其他NF网元如PCF网元直接交互访问，而第三方的AF网元必须通过NEF访问其他NF。
AMF网元：用于执行注册、连接、可达性、移动性管理。为UE和SMF网元提供会话管理消息传输通道，为用户接入时提供认证、鉴权功能，终端和无线的核心网控制面接入点，可以类比于4G的移动性管理(Mobility Management Entity，MME)实体。
SMF网元：用于负责隧道维护、IP地址分配和管理、UP功能选择、策略实施和QoS中的控制、计费数据采集、漫游等。
UE：为手持终端、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)终端或是其他可以接入网络的设备。终端设备与接入网设备之间采用某种空口技术相互通信。
(R)AN设备：为终端设备提供接入的设备，包含RAN设备和AN设备。RAN设备主要是3GPP网络无线网络设备，AN可以是non-3GPP定义的接入网设备。无线接入网(Radio Access Network，RAN)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、数据压缩和加密等功能。所述RAN设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在第五代(5th generation，5G)系统中，称为RAN或者gNB(5G NodeB)；在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)；在第三代(3rd generation，3G)系统中，称为节点B(Node B)等。
UPF网元：用于用户数据包的路由和转发、与外部数据网DN的数据交互、用户平面的QoS处理、流控规则实施(例如门控、重定向、流量转向)等；数据网络DN：指的是为用户提供数据传输服务的服务网络，如IMS(IP Multi-media Service,IP多媒体业务)、Internet等。例如运营商业务，互联网或者第三方业务等；UE通过UE到DN之间建立的PDU(Packet Data Unit，分组数据单元)会话，来访问数据网络(DN，Data Network)。
需要注意的是，本申请方案不仅可以适用于上述的5G系统架构中，还可以适用于但不限于长期演进(long term evolution，LTE)通信系统，以及未来演进的各种无线通信系统中。
另外，在5G系统中，为了保证业务端到端的服务质量，本申请实施例提供的一种服务质量的处理方法所适用的一种5G QoS模型架构，可参考图2所示。通常一个终端设备UE可以与5G系统建立一个或者多个分组数据单元PDU会话(PDU Session)，并且每个PDU会话中可以建立一个或者多个服务质量流(QoS flow)，每个服务质量流(QoS flow) 可以通过一个服务质量流的标识(QFI)进行识别。
该5G QoS模型可以支持保证比特率的QoS flow(GBR QoS flow)和不保证比特率的QoS flow(Non-GBR QoS flow)两种，并且可以根据对应的QoS profile，即QoS配置文件，确定当前业务流QoS flow为GBR QoS flow还是Non-GBR QoS flow。
针对GBR QoS flow，其对应的QoS配置文件具体可以包括以下QoS参数：5QI、分配和预留优先级ARP、保证流比特率GFBR和最大流比特率(Maximum Flow Bit Rate，MFBR)。由于该QoS配置文件中还可能包括通知控制Notification control，因此，可以根据QoS配置文件中是否包括通知控制Notification control，进一步的还可以将GBR QoS flow分为使用Notification control的GRB QoS flow和不使用Notification control的GBR QoS flow。
需要注意的是，针对使用Notification control的GRB QoS flow，若无线接入网RAN设备检测到对应的QoS flow资源不能被满足或者重新满足时，RAN设备可以通知会话管理SMF网元，从而SMF网元可以发起QoS flow删除或者修改流程。
针对Non-GBR QoS flow，其对应的QoS配置文件可以包含以下QoS参数：5QI、分配和预留优先级ARP；还可能包括反转QoS属性(Reflective QoS Attribute，RQA)。
下面针对上述的QoS参数进行详细介绍：
(1)、5QI：为一个标量，可以用于索引到对应的5G QoS特征，5QI可以包括标准化的5QI、预配置的5QI和动态分配的5QI。其中，标准化的5QI可以与一组标准化的5G QoS特征值一一对应；预配置的5QI对应的5G QoS特征值预配置在接入网络节点(AN)；对于动态分配的5QI对应的5G QoS特征包含在QoS配置文件中并发送给接入网络节点(AN)。
(2)、分配和预留优先级ARP：可以包含优先等级、抢占能力和被抢占能力。
(3)、反转QoS属性RQA：用于指示使用对应QoS flow传输的业务使用反转QoS；
(4)、通知控制Notification control：用于指示RAN在QoS flow的使用期当GFBR不能满足时是否通知网络；
(5)、保证流比特率GFBR：可以表示期望提供给GBR QoS flow的比特率；
(6)、最大流比特率MFBR：用于限制提供给GBR QoS flow的比特率，即提供给GBR QoS flow的最大比特率。如超过该比特率时，数据包可以被丢弃。
下面对上述使用Notification control的GRB QoS flow的控制流程进行详细介绍，参考图3所示，具体可以包括以下步骤：
S300：终端UE与网络侧建立PDU会话。
S301：UE与网络侧建立使用Notification control的GRB QoS flow(PCF网元可以向SMF网元下发PCC规则，SMF网元可以根据该PCC规则向无线接入网RAN设备发送指示信息)。
S302：在建立完成一段时间之后，若RAN设备检测到GBR QoS flow的QoS目标不能被满足时，即实际的保证比特率的服务质量流的服务质量QoS没有达到目标的服务质量，且该GBR QoS flow的配置文件中包含通知控制Notification control。
S303：RAN设备向接入和移动管理AMF网元发送N2消息，N2消息中包含PDU会话的身份标识ID和N2SM信息，N2SM信息中包含服务质量流的标识QFI，并且该N2SM信息用于指示该QoS flow的QoS目标不能被满足。
S304：AMF网元向SMF网元发送更新会话管理上下文的请求 Nsmf_PDUSessionUpdateSMContext，该请求中包含服务质量流的标识QFI和通知notification。
S305：SMF网元接收到该请求后，当SMF网元确定动态的PCC规则可以用于该PDU会话，并且PCF网元订阅的GBR QoS flow不能满足时，需要向PCF网元指示该事件，SMF网元将执行会话管理策略修改流程，以上报该事件。当SMF网元确定动态的PCC规则不可以用于该DNN，SMF网元可以根据本地策略确定发起会话修改流程。
SMF网元执行会话管理策略修改流程可以包括如下：
S306：SMF网元向AMF网元发送Namf_Communication_N1N2MessageTransfer，消息中包含N2SM信息和N1SM容器。
当SMF网元确定删除GBR QoS flow时，N2SM信息中包含PDU会话ID和该服务质量流QoS flow的标识QFI，N1SM容器中包含PDU会话的ID和受影响的QoS规则以及对应的QoS规则操作(即删除)。
当SMF网元确定修改GBR QoS flow时，N2SM信息中包PDU会话ID、该服务质量流QoS flow的标识QFI和QoS的配置文件；N1SM容器中包含PDU会话ID和受影响的QoS规则以及对应的QoS规则操作(如删除或者修改)。
S307：AMF网元向RAN设备发送N2PDU会话请求，请求中包含从上述的N2SM信息，以及N2NAS消息；其中，NAS消息包含PDU会话ID和N1SM容器。
S308：RAN设备可以根据SMF网元发送的信息，与UE执行(R)AN特定的信令流程。若当前接入的是3GPP RAN，UE和AN之间将执行RRC连接重新配置修改对应的RAN设备资源。
S309：RAN设备向AMF网元发送N2会话的响应消息，该响应消息中包含N2SM信息。
S310a：AMF网元向SMF网元发送Nsmf_PDU Session_Update SM Context服务操作，服务中包含N2SM信息。
S310b：SMF网元向AMF网元返回Nsmf_PDU Session_Update SM Context响应。
S311：UE向RAN设备发送PDU会话修改命令的确认消息，该息中包含PDU会话ID和N1SM容器，其中，N1SM容器由PDU会话修改命令确定。
S312：RAN网元向网元AMF转发N2NAS消息。

S315：SMF网元与PCF网元执行会话管理策略修改流程，即SMF网元将通知PCF网元对应的PCC规则是否执行。
若在SMF网元已接收“GFBR不能再保证”的通知，并且NG-RAN设备确定当前又可以满足GFBR时，NG-RAN设备应向SMF网元发送通知，例如“可以再次保证GFBR”的通知。
需要注意的是，针对其他QoS flow的控制(即Non-GBR QoS flow和不需要Notification  control的GBR QoS flow)，当RAN设备检测到资源不能满足时，将直接向SMF网元发起删除该QoS flow的流程，而非上报指示信息，由SMF网元确定对该QoS flow的控制。
例如，上述流程中的服务质量流也可以称为业务流。
综上所述，针对使用通知控制信息的GBR QoS flow，当建立该GBR QoS flow之后，任意时刻，若RAN设备检测到对应的GBR QoS flow的QoS未达到目标服务质量时，向会话管理功能SMF网元发送指示信息，SMF网元可以根据该指示信息，发起修改或删除该GBR QoS flow的QoS参数/属性的处理流程，即处理QoS flow的服务质量参数的流程。
然而，在现有技术中，(R)AN设备对QoS flow的QoS参数/属性进行处理时，通常需要额外的信令交互，才能准确的处理QoS参数/属性，因而会导致处理QoS flow的QoS参数/属性的效率较低。
因此，亟待需要提出一种服务质量的处理方法，可以对业务流的服务质量进行准确的处理，既可以使得业务流的服务质量满足对应的目标服务质量，也可以减少处理过程所涉及的信令交互。
本申请实施例提供了一种服务质量的处理方法，该方法可适用于但不限于图1A-图1B的5G系统架构，并且该方法可以由本申请涉及到的网元执行，或者由涉及到的网元对应的芯片执行，本申请中的网元可以为物理上的实体网元，也可以是虚拟的网元，本申请对涉及的网元的形态不做具体限定。
参阅图4所示，该图示出了本申请实施例提供的一种具体实施方法的流程图，具体该方法可以包括如下步骤：
S401：会话管理网元从策略控制网元接收第一规则。
具体的，该第一规则中包括方向信息和服务质量的通知控制信息，该方向信息指示第一业务流的方向，该方向信息包括上行方向和/或下行方向，该服务质量的通知控制信息用于指示第一业务流的服务质量符合预设的上报条件时向策略控制网元发送通知信息，第一目标服务质量与第一业务流对应。
可选的，该预设的上报条件可以包括：第一业务流的服务质量不满足第一业务流的目标服务质量，或满足第一业务流的目标服务质量。例如，该满足第一业务流的目标服务质量可以为重新满足第一业务流的目标服务质量，也就是说，该第一业务流的状态从不满足第一业务流的目标服务质量，改变为满足第一业务流的目标服务质量。
需要注意的是，策略控制网元通过会话管理网元向接入网设备下发第一规则中的方向信息，既可以用于指示接入网设备上报对应方向的服务质量的通知信息，以使得网络侧调整对应方向业务流的服务质量参数，也可以作为会话管理网元将规则绑定至业务流的参数，例如会话管理网元对第一规则与业务流进行绑定时，需要考虑该业务流的方向信息与第一规则中的方向信息是否相同。
S402：会话管理网元向接入网设备发送方向信息和服务质量的通知控制信息。
可选的，会话管理网元向接入网设备发送方向信息和服务质量的通知控制信息之前，还包括：会话管理网元根据方向信息和服务质量的通知控制信息，将第一规则与第一业务流进行绑定。
具体的，会话管理网元根据方向信息和服务质量的通知控制信息，将第一规则与第一业务流进行绑定，可以包括但不限于包括以下两种实现方式：
第一种实现方式：第一业务流可以为当前已存在的业务流；会话管理网元确定该第一 业务流的方向信息与第一规则中的方向信息相同，且第一业务流的服务质量的通知控制信息与第一规则中的服务质量的通知控制信息相同；会话管理网元将第一规则与第一业务流进行绑定，绑定后的第一规则与第一业务流对应。
第二种实现方式：会话管理网元创建第一业务流，第一业务流的方向信息与第一规则中的方向信息相同，且第一业务流的服务质量的通知控制信息与第一规则中的服务质量的通知控制信息相同；会话管理网元将第一规则与第一业务流进行绑定，绑定后的第一规则与第一业务流对应。
基于该第二种实现方式之后，会话管理网元向接入网设备发送第一消息，第一消息包括第一业务流的标识信息和第一业务流对应的方向，通过该步骤，会话管理网元通过向接入网设备发送第一消息，用于告知接入网会话管理网元所创建的第一业务流的标识信息和方向。
需要注意的是，在执行上述两种绑定方式时，第一规则还可能包括其它的信息，例如设定参数/属性，那么该第一业务流的该类型参数/属性也要与第一规则中包括的对应参数/属性相同，本申请对该其它的信息不做具体限定。
另外，上述会话管理网元按照方向信息将第一规则与第一业务流进行绑定的步骤属于可选步骤，即该步骤可执行，也可不执行，若会话管理网元不执行该步骤时，会话管理网元按照背景技术所介绍方式将第一规则与第一业务流进行绑定。若会话管理网元执行该绑定步骤时，会话管理网元向接入网设备发送的第一业务流的信息所包括的方向信息与第一规则中包括的方向信息相同。若会话管理网元不执行该绑定步骤时，会话管理网元向接入网设备发送的第一业务流的信息中所包括的方向信息，可以为所有与该业务流绑定的PCC规则中的方向信息。例如，当有多个PCC规则绑定至同一个业务流，且该多个PCC规则包含的方向信息不同时，会话管理网元需要针对该业务流，下发多个不同的方向信息。
S403：接入网设备确定第一方向的第一业务流的服务质量符合上述预设的上报条件，该第一方向包括上述方向信息中的至少一个。
例如，接入网确定当前上行方向的流比特率不满足或重新满足上行方向的保证流比特率GFBR。
S404：接入网设备向会话管理网元发送第一方向的服务质量的通知信息。
第一方向的服务质量的通知信息用于通知第一方向的第一业务流的服务质量不满足第一目标服务质量或重新满足第一目标服务质量。
具体的，在执行该步骤S404时，可能包括以下几种情况：
第一种情况：会话管理网元只订阅了单方向的服务质量的通知控制信息，例如第一方向的服务质量的通知控制信息，则接入网设备从会话管理网元接收到该单方向信息，即上行方向或下行方向，以及服务质量的通知控制信息之后，接入网设备将只针对该方向的服务质量进行检测，当接入网设备确定该方向的服务质量不满足或重新满足对应方向的目标服务质量，可以只需向会话管理网元发送服务质量的通知信息，无需向会话管理网元发送方向信息，会话管理网元接收该服务质量的通知信息之后，可以确定为第一方向的服务质量的通知信息。
第二种情况：会话管理网元订阅双方向的服务质量的通知控制信息，即上行方向和下行方向的服务质量的通知控制信息，接入网设备从会话管理网元接收到方向信息以及服务质量的通知控制信息之后，若接入网设备检测某一个方向的服务质量，例如第一方向的服 务质量，不满足对应方向的目标服务质量，需要向会话管理网元发送第一方向和该方向的服务质量的通知信息，会话管理网元接收该第一方向和该方向的服务质量的通知信息。
S405：会话管理网元向策略控制网元发送第一方向和第一业务流的信息。
具体的，该第一业务流的信息可以包括服务数据流的ID，还可以包括“不满足或重新满足”的指示信息。由于第一业务流的信息可用于向策略控制网元告知第一业务流的信息对应的业务流的服务质量参数需要被调整，因此，本申请对第一业务流的信息可不做具体限定。
S406：会话管理网元从策略控制网元接收第二规则。
具体的，第二规则中包括第一方向和第一方向的业务流的第二服务质量参数，第二服务质量参数用于指示当前第一方向的业务流的服务质量，第二服务质量参数由策略控制网元在接收第一方向和第一业务流的信息之后对第一方向的业务流的第一服务质量参数进行更新得到的。
可选的，本申请方案中的服务质量参数包括但不限于包括以下一项或多项：优先等级、包时延预算、最大数据突发量、5G服务质量的标识5QI、通知控制信息。
应理解，在执行该步骤S406之前，由于策略控制网元侧已存在第一方向的业务流的服务质量参数，即第一服务质量参数，因此，策略控制网元在接收到由会话管理网元发送的第一方向和第一业务流的信息之后，确定该第一业务流的服务质量不满足或重新满足第一目标服务质量，则将该方向的第一业务流的第一服务质量参数修改为第二服务质量参数，以保证该第一业务流的服务质量满足第一目标服务质量。
在一种实施方式中，会话管理网元从策略控制网元接收第二规则之后，还包括：会话管理网元根据第一方向和第二服务质量参数，将第二规则与第二业务流进行绑定。
具体的，会话管理网元根据第一方向和第二服务质量参数，将第二规则与第二业务流进行绑定，包括但不限于以下两种实现方式：
第一种实现方式：第二业务流为会话管理网元中存在的业务流，会话管理网元确定第二业务流的方向为第一方向，且第二业务流的服务质量参数与第二规则中的第二服务质量参数相同；会话管理网元将第二规则与第二业务流进行绑定，绑定后的第二规则与第二业务流对应。
第二种实现方式：会话管理网元创建第二业务流，第二业务流的方向为第一方向，且第二业务流的服务质量参数与第二规则中的第二服务质量参数相同；会话管理网元将第二规则与第二业务流进行绑定，绑定后的第二规则与第二业务流对应。
基于该第二种实现方式之后，会话管理网元向接入网设备发送第二消息，该第二消息包括第二业务流的标识信息和第二业务流对应的方向。通过该步骤，会话管理网元通过向接入网设备发送第二消息，用于告知接入网会话管理网元所创建的第二业务流的标识信息和方向。
需要注意的是，在执行上述两种绑定方式时，还需要确定第二业务流的其它信息，例如参数/属性，与第二规则中包括的参数/属性也要相同，本申请对参数/属性不做具体限定。
可选的，上述涉及的规则可以为但不仅限为：PCC规则。
S407：会话管理网元向接入网设备发送第一方向和第二服务质量参数。
第二服务质量参数为第一业务流的第二服务质量参数。
在一种实施方式中，会话管理网元还需要向终端设备发送第一方向和第一业务流的第 二服务质量参数。
应理解，会话管理网元可以同时分别向接入网设备和终端发送第一方向和第一业务流的第二服务质量参数，也可以不同时分别向接入网设备和终端发送第一方向和第一业务流的第二服务质量参数。
需要注意的是，在本申请中执行上述服务质量处理的所有步骤之前，即终端设备与网络侧进行交互或通信之前，终端与网络侧已经建立会话连接，例如PDU会话。另外，由于PCF网元可以不根据QNC单独调整某个方向上的参数/属性值，因此，上述步骤S406-S407还可以与上述步骤S401-S405分开执行，即步骤S406-S407可以独立执行。
综上所述，图4示出的一种具体实施方法中，会话管理网元从策略控制网元接收第一规则，将第一规则中包括的方向信息和服务质量的通知控制信息发给接入网设备，该服务质量的通知控制信息用于指示第一业务流的服务质量不满足第一目标服务质量或重新满足所述第一目标服务质量时向该策略控制网元发送通知信息。当接入网设备检测到第一方向的第一业务流的服务质量不满足该第一目标服务质量或重新满足该第一目标服务质量，该接入网设备向会话管理网元发送第一方向的服务质量的通知信息，会话管理网元接收该第一方向的服务质量的通知信息之后，向策略控制网元发送第一方向和该第一业务流的信息，从而策略控制网元可以根据该第一方向和该第一业务流的信息，对该第一方向的第一业务流进行准确的处理，以使得该第一方向的第一业务流的服务质量可以满足第一目标服务质量，并且在服务质量处理过程中传输的信息携带方向信息，无需增加传输方向信息的交互，从而可减少服务质量处理过程中的额外信令交互。
基于上述实施例提供的一种具体实施方法，下面结合具体的一个具体的实施例，以详细说明本申请的方法。参考图5所示，该实施例中所涉及网络侧的执行对象为网元，该实施例中的PCF网元为上述图4中的策略控制网元，该实施例中的SMF网元为上述图4中的会话管理网元，该实施例中的AN设备为上述图4中的接入网设备，该实施例的具体实施流程如下：
S500：UE与网络侧建立PDU会话。
终端UE与网络侧建立PDU会话，具体可参考现有的技术方案，本申请不做具体介绍。
应理解，该网络侧主要涉及包括但不限于：接入网设备、SMF网元、PCF网元。
S501：PCF网元向SMF网元发送第一PCC规则。
例如，该第一PCC规则中包括方向信息和QNC信息。
相应的，SMF网元接收该第一PCC规则。
具体的，方向信息指示第一业务流的方向，方向信息包括上行方向和/或下行方向，QNC信息用于指示第一业务流的服务质量不满足第一目标服务质量或重新满足第一目标服务质量时向PCF网元发送通知信息，第一目标服务质量与第一业务流对应。
例如，若第一PCC规则中的方向信息包括上行方向，那么QNC信息可以用于指示当前上行方向的业务流的服务质量不满足或重新满足对应方向的目标服务质量时向PCF网元发送通知信息。若第一PCC规则中的方向信息包括下行方向，那么QNC信息用于指示当前下行方向的业务流的服务质量不满足或重新满足对应方向的目标服务质量时向PCF网元发送通知信息。
需要注意的是，该步骤S501与上述步骤S401相对应，可以互相参考。
另外，第一PCC规则中包括的QNC信息以及对应方向信息可以设置为QNC+方向信 息，还可以设置为一个单独的参数，即一个单独参数可以指示上行方向需要使用QNC信息，另一个单一参数可以指示下行方向需要使用QNC信息，具体如何设置参数，本申请不做具体限定。例如，若第一PCC规则中包括的QNC信息以及对应方向信息可以设置为A时，则可以指示上行方向的业务流的服务质量不满足或重新满足对应方向的目标服务质量时向PCF网元发送通知信息；若第一PCC规则中包括的QNC信息以及对应方向信息可以设置为B时，则可以指示下行方向的业务流的服务质量不满足或重新满足对应方向的目标服务质量时向PCF网元发送通知信息。
S502：SMF网元将第一PCC规则与第一业务流进行绑定。
例如，业务流可以为QoS flow。
具体的，SMF网元接收到第一PCC规则之后，SMF网元确定SMF中是否已存在第一业务流，该第一业务流的方向信息与第一PCC规则中包括的方向信息相同，且该第一业务流的服务质量的通知控制QNC信息与第一PCC规则中包括的服务质量的通知控制QNC信息相同。
应理解，第一业务流的其它参数也要与第一PCC规则中包括的对应参数相同，本申请对具体参数类型不作具体限定。
若SMF网元中已存在该第一业务流，SMF网元将第一PCC规则与该第一业务流绑定；若SMF网元中不存在该第一业务流，SMF网元创建该第一业务流，然后，将第一PCC规则与该创建的第一业务流绑定，并SMF网元向AN设备发送第一消息，该第一消息包括第一业务流的标识信息和第一业务流对应的方向。
应理解，SMF网元创建的第一业务流的方向信息与第一PCC规则中的方向信息相同，且创建的第一业务流的QNC信息与第一PCC规则中的QNC信息相同。另外，SMF网元创建的第一业务流的其它参数与第一PCC规则中包括的对应参数也均相同，本申请对具体的参数类型不作具体限定。

S503：SMF网元向AN设备发送方向信息和QNC信息。
相应的，AN设备接收该方向信息和QNC信息。
其中，该方向信息和QNC信息可以通过携带在第一服务质量的文件中，例如QoS Profile，由SMF网元向AN设备发送该第一服务质量的文件。
需要注意的是，该步骤S503与上述步骤S402相对应，可以互相参考。另外，若SMF网元已执行上述步骤S502中的绑定步骤之后，SMF网元向AN设备发送的方向信息包括第一业务流的方向。若SMF网元未执行上述步骤S502中的绑定步骤，SMF网元向AN设备发送的方向信息与第一PCC规则中包括的方向信息相同。
S504：AN设备向SMF网元发送第一方向的服务质量的通知信息，第一方向的服务质量的通知信息用于通知第一方向的第一业务流的服务质量不满足第一目标服务质量或重新满足第一目标服务质量，第一方向包括上述方向信息中的至少一个。
相应的，SMF网元接收该第一方向的服务质量的通知信息。
具体的，当AN设备接收携带方向信息和QNC信息的QoS Profile之后，根据QoS Profile中包括的方向信息，例如第一方向，AN设备若确定第一方向的业务流的服务质量不满足 或重新满足该方向的目标服务质量时，AN设备向SMF网元发送第一方向的服务质量的通知信息。
需要注意的是，若SMF网元只订阅了单方向的QNC信息，或者已执行上述步骤S502步骤中的绑定，即单方向的绑定，AN设备可以不向SMF网元发送方向信息，SMF网元在接收到服务质量的通知信息后，自身也可以确定相应的方向。若SMF网元订阅了双方向的QNC信息，且未执行上述步骤S502步骤中的绑定，那么AN设备向SMF网元发送服务质量的通知信息时，还需要发送相应的方向信息，即第一方向的信息，SMF网元才能确定相应方向的服务质量的参数/属性需要更新，进一步上报给PCF网元。
需要注意的是，该步骤S504与上述步骤S403和步骤S404相对应，可以互相参考。
S505：SMF网元向PCF网元发送第一方向的服务质量的通知信息。
相应的，PCF网元接收该第一方向的服务质量的通知信息。
具体的，该步骤S505中SMF网元向PCF网元发送的第一方向的服务质量的通知信息与上述步骤S504中SMF网元从AN设备接收到的第一方向的服务质量的通知信息相同，该第一方向的服务质量的通知信息用于通知第一方向的第一业务流的服务质量不满足第一目标服务质量或重新满足第一目标服务质量，从而也可指示PCF网元对第一方向的业务流的服务质量参数/属性，即服务质量的服务质量参数，进行调整。
可选的，服务质量参数/属性可以包括但不限于包括以下一项或多项：优先等级、包时延预算、最大数据突发量、服务质量的标识、通知控制信息。
需要注意的是，该步骤S505与上述步骤S405相对应，可以互相参考。
S506：PCF网元根据第一方向的服务质量的通知信息，更新第一PCC规则，得到第二PCC规则。
具体的，PCF网元接收到第一方向的服务质量的通知信息之后，针对第一方向的业务流的服务质量参数/属性进行更新或调整，得到更新的第一方向的业务流的服务质量参数/属性。其中，PCF网元更新或调整该方向的业务流的服务质量参数/属性所采用的方式，本申请不做具体限定。

若SMF网元中已存在该第二业务流，则SMF网元将第二PCC规则与该第二业务流进行绑定，绑定后的第二PCC规则与第二业务流对应。
若SMF网元中不存在该第二业务流，则SMF网元创建第二业务流，将第二PCC规则与该第二业务流进行绑定。另外，SMF网元还向AN设备发送第二消息，第二消息包括由SMF网元创建的第二业务流的标识信息和第二业务流对应的方向。
需要注意的是，该第二业务流与上述步骤S502中的第一业务流不相同。

可选的，SMF网元可以将第一方向和更新的第一方向的业务流的服务质量参数/属性可以携带在第二服务质量的文件中，例如QoS Profile，发送给AN设备。
需要注意的是，该步骤S509与上述步骤S407相对应，可以互相参考。
S510：SMF网元向UE发送第一方向信息和更新后的第一方向的QoS参数/属性。
可选的，SMF可以将第一方向信息和更新后的第一方向的QoS参数/属性携带在第一方向的服务质量的规则中，发送给UE。
应理解SMF网元可以同时执行上述步骤S509和S510，也可以不同时执行上述步骤S509和S510执行，本申请不做具体限定。
需要注意的是，由于PCF网元可以不只根据QNC单独调整某个方向业务流的服务质量参数/属性值，因此，上述步骤S507-S510还可以与上述步骤S501-S506分开执行，即S507-S510可以作为一个单独的实例执行。
综上所述，该图5所示的实施例中，网络侧可以向接入网设备发送上行方向和/或下行方向信息以及服务质量的通知控制信息，接入网设备可以对当前业务流的服务质量进行检测，若确定某个方向业务流的服务质量不满足对应方向的目标服务质量时，可以向SMF网元发送该方向的服务质量的通知信息，SMF网元进一步向PCF发送该方向的服务质量的通知信息，从而PCF网元侧可以对该方向业务流的服务质量参数/属性进行调整。因此，该方案既可以保证网络使用的业务流的服务质量可以满足对应的目标服务质量，同时也可以减少处理业务流的服务质量参数/属性过程中的信令开销。
参阅图6所示，该图示出了本申请实施例提供的另一种具体实施方法的流程图，具体该方法可以包括如下步骤：
S601：会话管理网元从策略控制网元接收第一规则。
具体的，第一规则中包括服务质量的通知控制信息，例如QNC，该服务质量的通知控制信息用于指示上行方向或下行方向的业务流的服务质量符合预设的上报条件时向策略控制网元发送通知信息。
可选的，该预设的上报条件包括：当前业务流的上行方向和下行方向的服务质量参数不同，且第一方向的服务质量不满足或重新满足该方向的目标质量。
需要注意的是，该第一规则中只包括服务质量的通知控制信息，不包括方向信息。
S602：会话管理网元向接入网设备发送服务质量的通知控制信息。
相应的，接入网设备接收该服务质量的通知控制信息。
该步骤S602可以参考上述步骤S402，此处不再具体赘述。

应理解，上述步骤S607与S608可以同时执行，也可以不同时执行，本申请对此不做具体限定。
需要注意的是，由于PCF网元可以不根据QNC单独调整某个方向上的参数/属性值，因此，上述步骤S606-S608还可以与上述步骤S601-S605分开执行，即步骤S606-S608可以独立执行。
综上所述，图6示出的另一种具体实施方法中，会话管理网元从策略控制网元接收第一规则，然后，将第一规则中包括的服务质量的通知控制信息发给接入网设备，该服务质量的通知控制信息用于指示第一业务流的服务质量不满足第一目标服务质量或重新满足第一目标服务质量时向该策略控制网元发送通知信息。当接入网设备检测到当前上行方向的业务流和下行方向的业务流不对称，并且第一方向的业务流的服务质量不满足或重新满足该方向的目标质量，该接入网设备向会话管理网元发送第一方向的服务质量的通知信息和第一方向，会话管理网元接收该第一方向的服务质量的通知信息和第一方向之后，向策略控制网元发送该第一方向的第一业务流的信息，从而策略控制网元可以对该第一方向的第一业务流进行准确的处理，以使得该第一方向的第一业务流的服务质量可以满足第一目标服务质量。
基于上述实施例提供的另一种具体实施方法，下面结合具体的一个具体的实施例，以详细说明本申请的方法。参考图7所示，该实施例中所涉及网络侧的执行对象为网元，该实施例中的PCF网元为上述图6中的策略控制网元，该实施例中的SMF网元为上述图6中的会话管理网元，该实施例中的AN设备为上述图6中的接入网设备，该实施例的具体实施流程如下：
S700：UE与网络侧建立PDU会话。
UE与网络侧建立PDU会话，具体可参考现有的技术方案，本申请不做具体介绍。
应理解，该网络侧主要涉及包括但不限于：接入网设备、SMF网元、PCF网元。
S701：PCF网元向SMF网元发送第一PCC规则，该第一PCC规则中包括QNC信息； 其中，QNC信息用于指示业务流的服务质量不满足或重新满足对应的目标服务质量时进行上报。
需要注意的是，该步骤S701与上述步骤S601相对应，可以互相参考。
S702：SMF网元将第一PCC规则与第一业务流进行绑定。
具体的，SMF网元接收到第一PCC规则之后，确定SMF网元中是否已存在第一业务流，该第一业务流的QNC信息与第一PCC规则中包括的QNC信息相同，并且第一业务流的其它参数也要与第一PCC规则中包括的对应参数相同，本申请对参数类型不作具体限定。
若SMF网元中已存在该第一业务流，则SMF网元将第一PCC规则与该第一业务流绑定；若SMF网元中不存在该第一业务流，则SMF网元创建第一业务流，将第一PCC规则与该第一业务流绑定，并向AN设备发送第一消息，第一消息包括由SMF网元创建的第一业务流的标识信息和第一业务流的标识信息对应的方向。
应理解，SMF网元创建的第一业务流的服务质量的QNC信息以及其它的参数与第一PCC规则中包括的服务质量的通知控制QNC信息以及其它的参数均相同。
需要注意的是，该步骤S702与上述步骤S602中的绑定过程相对应，可以互相参考。
S703：SMF网元向AN设备发送QNC信息。
相应的，AN设备接收该QNC信息。
可选的，SMF网元可以将QNC信息携带在第一服务质量的文件中，例如QoS Profile，发送给AN设备。
应理解，SMF网元向AN设备发送的QNC信息与第一PCC规则中的QNC信息相同。
需要注意的是，该步骤S703与上述步骤S602相对应，可以互相参考。
S704：AN设备向SMF网元发送第一方向信息和第一方向的服务质量的通知信息。
相应的，SMF网元接收第一方向信息和第一方向的服务质量的通知信息。
可选的，AN设备可以将第一方向信息和第一方向的服务质量的通知信息携带在N2信令中，发送给SMF网元。
具体的，AN设备接收到QNC信息之后，确定当前上行方向的服务质量参数/属性的值与下行方向的服务质量参数/属性的值不同，且第一方向的业务流的服务质量不满足或重新满足该方向的目标服务质量时，第一方向可以上行方向或下行方向，此时，AN设备可以根据服务质量的通知控制QNC信息，向SMF网元发送第一方向的信息和第一方向的服务质量的通知信息。
应理解，由于SMF网元不能确定方向信息，因此，AN设备在确定上行方向或下行方向的业务流的服务质量不满足或重新满足相应方向的目标服务质量时，AN设备向SMF网发送服务质量的通知信息时，还需要发送对应的方向信息，从而SMF网元可以根据服务质量的通知信息和对应的方向信息，确定具体哪个方向的业务流的服务质量参数/属性需要调整，进而上报给PCF网元执行。
可选的，服务质量参数/属性可以包括但不限于包括以下一项或多项：优先等级、包时延预算、最大数据突发量、服务质量的标识、通知控制信息。
需要注意的是，该步骤S704与上述步骤S603和S604相对应，可以互相参考。
S705：SMF网元向PCF网元发送第一方向的服务质量的通知信息。
需要注意的是，该步骤S705与上述步骤S605相对应，可以互相参考。
S706：PCF网元根据第一方向的服务质量的通知信息，更新第一PCC规则，得到第二PCC规则。
具体的，PCF网元接收到第一方向的服务质量的通知信息之后，根据该信息中包括的第一方向的信息，确定第一方向业务流的服务质量参数/属性，然后，对该服务质量QoS参数/属性进行更新或调整，得到更新后的第一方向业务流的服务质量参数/属性。
需要注意的是，PCF接收网元到SMF网元上报的第一方向的服务质量的通知信息之后，PCF网元还可以该信息进一步上报给AF网元。
S707：PCF网元向SMF网元发送第二PCC规则，该第二PCC规则中包括第一方向的信息和更新后的第一方向业务流的服务质量参数/属性。
相应的，SMF网元接收该第二PCC规则。
需要注意的是，该步骤S707与上述步骤S606相对应，可以互相参考。
S708：SMF网元将第二PCC规则与第二业务流进行绑定。
该步骤S708与上述步骤S607中的绑定过程相对应，可以互相参考。
S709：SMF网元向AN设备发送第一方向的信息和更新后的第一方向业务流的服务质量参数/属性。
需要注意的是，该步骤S709与上述步骤S607相对应，可以互相参考。
S710：SMF网元向UE发送第一方向的信息和更新后的第一方向业务流的服务质量参数/属性。
需要注意的是，该步骤S710与上述步骤S608相对应，可以互相参考。
应理解，SMF网元可以同时执行上述步骤S709和S710，也可以不同时执行上述步骤S709和S710执行，本申请不做具体限定。
需要注意的是，PCF网元可以不只根据QNC单独调整某个方向上的参数/属性值，因此，上述步骤S707-S710还可以与上述步骤S701-S706分开执行，即S707-S710可以作为一个单独的实例执行。
综上所述，该图7所示的实施中，AN设备在接收到网络侧发送的QNC信息之后，确定当前业务流的上行方向和下行方向的服务质量参数/属性值不同，且第一方向的业务流的服务质量不满足对应方向的目标服务质量时，需要向SMF网元发送第一方向的信息和服务质量的通知信息，进一步将第一方向的信息和服务质量的通知信息发送给PCF网元，从而PCF可以知晓哪个方向业务流的服务质量参数/属性需要调整，进而执行该调整。因此，该方案既可以使网络使用的业务流的服务质量可以满足对应的目标服务质量，也可以减少处理业务流的服务质量参数/属性过程中的信令开销。
参阅图8所示，示出了本申请实施例提供的又一种具体实施方法的流程图，具体可以包括如下步骤：
S801：会话管理网元从策略控制网元接收第一规则。
在一种实施方式中，会话管理网元从策略控制网元接收第一规则之前，还包括：策略控制网元在从应用功能网元接收业务流的需求信息，该需求信息用于指示策略控制网元向会话管理网元发送第一规则。
具体的，该第一规则中包括方向信息和业务流的服务质量参数集合；其中，方向信息包括上行方向和/或下行方向，该业务流的服务质量参数集合中包括第一服务质量参数集合和/或第二服务质量参数集合，第一服务质量参数集合包括上行方向的服务质量参数，第二 服务质量参数集合包括下行方向的服务质量参数。例如，该业务流的服务质量参数集合可以为可选择的服务质量的参数(Alternative QoS Parameter，AQP)。
在一种实施方式中，该第一服务质量参数集合中的一个或多个服务质量参数具有优先级，该第二服务质量参数集合中的一个或多个服务质量参数具有优先级。
示例性的，上述业务流的服务质量参数集合可以通过但不限于以下方式获得：
首先，将已获取的多个服务质量参数按照两个方向，即上行方向和下行方向，划分为两个服务质量参数集合：第一服务质量参数集合和第二服务质量参数集合，第一服务质量参数集合包括上行方向的服务质量参数，第二服务质量参数集合包括下行方向的服务质量参数。其次，针对每个服务质量参数集合，可以按照优先级的等级从高到低或者从低到高，对不同优先级所对应的服务质量的服务质量参数进行排列。
参考表1所示，服务质量的服务质量参数以分组时延预算PDB和保证流比特率GFBR为例，按照上行方向和下行方向，将不同优先等级的分组时延预算PDB和保证流比特率GFBR分成两组，即上行方向的第一服务质量参数集合和下行方向的第二服务质量参数集合，并且每组按照从高到低的优先等级进行排列，即优先级为数字1的等级比优先级为数字2的等级高，优先级为数字2的等级比优先级为数字3的等级高，以此类推。在实现时，也可以按照排列顺序表达优先级，不必有显示的优先级值。
表1
优先级 第一服务质量参数集合 第二服务质量参数集合
1 PDB1、GFBR1 PDB3、GFBR3
2 PDB2、GFBR1 PDB4、GFBR4
3 PDB2、GFBR2 PDB5、GFBR5
… … …
需要注意的是，可以由策略控制网元获得上述业务流的服务质量参数集合，然后将业务流的服务质量参数集合携带在第一规则中，发送给会话管理网元。因此，具体由哪个网元执行上述该划分，本申请不做具体限定。
S802：会话管理网元向接入网设备发送方向信息和服务质量的服务质量参数集合。
相应的，接入网设备接收该方向信息和服务质量的服务质量参数集合。
可选的，会话管理网元向接入网设备发送服务质量的服务质量参数集合之前，还包括：会话管理网元根据方向信息和业务流的服务质量参数集合，将第一规则与业务流进行绑定。
具体的，会话管理网元根据方向信息和业务流的服务质量参数集合，将第一规则与业务流进行绑定，可以包括但不限于包括以下两种实现方式：
第一种实现方式：会话管理网元确定会话管理网元中存在第一业务流，该第一业务流的方向信息与方向信息中的上行方向的信息相同，且第一服务质量参数集合包含第一业务流的服务质量参数，会话管理网元将第一规则与第一业务流进行绑定；或者会话管理网元确定第一业务流的方向信息与第一规则中下行方向的信息相同，且第二服务质量参数集合包含第一业务流的服务质量参数，会话管理网元将第一规则与第一业务流进行绑定。
例如，第一业务流的方向信息与第一规则中的方向信息相同，且均为上行方向信息，第一服务质量参数集合中包括第一业务流的服务质量参数。
第二种实现方式：会话管理网元创建第一业务流，该第一业务流的方向信息与方向信息中的上行方向的信息相同，且第一服务质量参数集合包含第一业务流的服务质量参数， 会话管理网元将第一规则与第一业务流进行绑定；或者该第一业务流的方向信息与第一规则中下行方向的信息相同，且第二服务质量参数集合包含第一业务流的服务质量参数，会话管理网元将第一规则与第一业务流进行绑定。
另外，会话管理网元还向接入网设备发送第一消息，第一消息包括由会话管理网元创建的第一业务流的标识信息和第一业务流对应的方向。
当然在实现时，会话管理网元还可以将包含服务质量的服务质量参数集合的第一规则绑定至单独的业务流，即该业务流中没有绑定其他规则。
S803：接入网设备确定第一方向的第一业务流的服务质量不满足第一方向的第一业务流的目标服务质量，第一方向包括上行方向和/或下行方向。
具体的，当接入网设备接收第一方向的第一业务流时，检测确定第一方向的第一业务流的第一服务质量参数不满足第一方向的第一业务流的目标服务质量参数。
例如，接入网确定当前上行方向的流比特率不满足上行方向的保证流比特率GFBR。
S804：接入网设备从服务质量参数集合，选择第二服务质量参数，该第二服务质量参数为该第一方向的第一业务流的更新后的服务质量参数。
在一种实施方式中，接入网设备根据第一方向和业务流的服务质量参数集合，选择第二服务质量参数，具体包括以下：首先，接入网设备从业务流的服务质量参数集合中，选择与该第一方向一致的服务质量参数集合；然后，接入网设备从该服务质量参数集合中选择优先级最高的服务质量参数为第二服务质量参数；或者，若第一服务质量参数为该服务质量参数集合中的一个，接入网设备从该服务质量参数集合中选择优先级低于所述第一服务质量参数的一个或多个服务质量参数，将该一个或多个服务质量参数中优先级最高的服务质量参数为第二服务质量参数。
应理解，该第一服务质量参数为第一方向的业务流的更新前的服务质量参数。
例如，接入网设备确定当前上行方向的服务质量不满足或重新满足上行方向的目标服务质量时，参考上述表1，接入网设备可以从第一服务质量参数集合中，将优先级最高的服务质量参数作为当前上行方向业务流的服务质量参数；或者若当前上行方向业务流的服务质量参数对应优先级3，那么接入网设备从第一服务质量参数集合中选择优先级低于3的一个或多个服务质量参数，然后，从优先级低于3的一个或多个服务质量参数中选择优先级最高的服务质量参数作为当前上行方向业务流的服务质量参数。
可选的，上述涉及的规则可以为但不限于：PCC规则。
应理解，在本申请中执行服务质量处理的所有步骤之前，即UE与网络侧进行交互或通信之前，终端与网络侧已经建立会话连接，例如PDU会话。
在执行该步骤S804之后，接入网设备将更新后第一方向的服务质量的第二服务质量参数发送给会话管理网元，以进行会话的修改，例如PDU会话的修改。
综上所述，图8示出的又一种具体实施方法中，接入网设备从会话管理网元接收业务流的服务质量参数集合，当接入网设备确定第一方向的业务流的服务质量不满足该第一方向的业务流的目标服务质量时，可以根据该第一方向和该业务流的服务质量参数集合，选择第二服务质量参数作为第一方向的业务流更新后的服务质量参数。该方法中接入网设备在检测某个方向的业务流不满足该方向的业务流的目标服务质量时，可以自行更新该方向的业务流的服务质量参数，从而不仅可以使得该方向的业务流的服务质量满足目标需求，并且减少了处理该方向的服务质量的系统开销。
基于上述实施例提供的一种具体实施方法，下面结合具体的一个具体的实施例，以详细说明本申请的方法。参考图9所示，该实施例中所涉及网络侧的执行对象为网元，该实施例中的PCF网元为上述图8中的策略控制网元，该实施例中的SMF网元为上述图8中的会话管理网元，该实施例中的AN设备为上述图8中的接入网设备，该实施例的具体实施流程如下：
S900：UE与网络侧建立PDU会话。
UE与网络侧建立PDU会话，具体可参考现有的技术方案，本申请不做具体介绍。
应理解，该网络侧主要涉及包括但不限于：接入网设备、SMF网元、PCF网元。
S901：PCF网元向SMF网元发送第一PCC规则。
具体的，该第一PCC规则中包括方向信息和AQP，即服务质量参数/属性集合。在执行该步骤S901时，当第一PCC规则中包括AQP时，可以通过以下方式获得业务流的服务质量参数/属性集合：
根据上行方向和下行方向，将对应的业务流的服务质量参数/属性分成两组，即包括上行方向的服务质量参数/属性的第一集合、包括下行方向的服务质量参数/属性第二集合，并且每个集合按照业务流的优先级值，以从小到大，或以从大到小方式进行排列，具体如表1所示(从小到大方式，优先级值越小，则等级越高)。但在实现时，也可以按照排列顺序表达优先级，不必有显示的优先级值。
需要注意的是，该步骤S901与上述步骤S801相对应，可以互相参考。
另外，在实现时可以执行步骤S901之前，PCF网元已执行上述的划分，以供后续步骤使用；其中，服务质量参数/属性包括但不限于上述表1中的包时延预算PDB和保证流比特率GFBR。另外，PCC规则中在AQP之外还可以存在其他的服务质量参数/属性。一般认为优先使用AQP之外的服务质量参数/属性，在不能满足的情况下再使用AQP中的服务质量参数/属性。
S902：SMF网元将第一PCC规则与业务流进行绑定。
该步骤S902为可选的步骤，具体可参考步骤S802中所述的绑定过程，此处不再具体赘述。
S903：SMF网元向AN设备发送方向信息和AQP。
例如，该AQP为服务质量参数/属性集合。
可选的，SMF将方向信息和AQP携带在第一服务质量的文件中，例如QoS Profile、Alternative QoS Profile，发送给AN设备。其中，Alternative QoS Profile可以有多个。
需要注意的是，该步骤S903与上述步骤S802相对应，可以互相参考。
S904：AN设备确定第一方向的业务流的服务质量不能满足对应方向的目标服务质量时，根据服务质量参数/属性集合，重新选择第一方向的服务质量参数/属性，第一方向为上行方向或下行方向。
需要注意的是，该步骤S904与上述步骤S803相对应，可以互相参考。
具体的，AN设备接收方向信息和AQP之后，若确定第一方向的业务流的服务质量不能满足对应方向的目标服务质量时，首先，AN设备从服务质量参数/属性集合中，确定与第一方向一致的集合，从该集合中，将优先级最高的服务质量参数/属性作为第一方向的业务流的服务质量参数/属性，或者，AN设备从该集合中，选择优先级大于第一方向的服务质量参数/属性的一个或多个服务质量参数/属性，然后从该一个或多个服务质量参数/属性 中选择优先级最高的服务质量参数/属性作为第一方向的业务流的服务质量参数/属性。
例如，AN设备确定当前上行方向的GFBR1不能满足上行方向的目标GFBR时，AN设备在上行方向对应的第一集合中，将当前上行方向的GFBR1更新为该第一集合中优先级最高的GFBR，或者若当前上行GFBR1对应的优先级为3，从第一集合中，选择优先级小于3的一个或多个GFBR，然后将当前上行方向的GFBR1更新为该一个或多个GFBR中优先级最高的GFBR。
根据上述步骤S904，若AN设备在确定第一方向的业务流的服务质量依然不能满足对应方向的目标服务质量时，可以参考上述步骤S904继续进行调整或更改，从而最终可保证当前第一方向的业务流的服务质量满足对应方向的目标服务质量。
在一种较具体的实现方法中，若AN设备确定第一方向业务流的服务质量无法满足服务质量的配置文件需求时，以GFBR为例，AN设备应向SMF网元发送“第一方向GFBR不能再得到保证”的通知。AN设备在向SMF网元发送“第一方向GFBR不能再保证”的通知之前，应(按第一方向的优先级顺序)检查Alternative QoS Profile是否存在有对应的GFBR可以满足的。如果存在，AN设备应指示使用具有最高优先级的匹配替代QoS配置文件，并通知SMF网元；如果不存在，AN设备向SMF网元发送“第一方向无法再保证GFBR”的通知，以指示无法满足优先级最低的Alternative QoS Profile(除非接入网侧的特定条件要求为此释放接入网资源QoS流，例如，由于无线链路故障或内部拥塞)。
如果AN设备已向SMF网元发送“第一方向GFBR不能再保证”的通知，并且AN设备确定该方向当前满足的QoS需求，例如GFBR、PDB或PER与上次通知中指示的情况不同，即变好或变坏，此时，AN设备应向SMF网元发送通知，即“第一方向可以再次保证GFBR”或“第一方向不能再保证GFBR”，以指示当前情况，除非接入网侧的特定条件要求为此释放接入网资源QoS流，例如，由于无线链路故障或内部拥塞。
AN设备应始终尝试满足服务质量的配置文件，例如QoS Profile，如果不可能，则从Alternative QoS Profile中使用具有更高优先级的匹配替代服务质量的配置文件，即从AQP中使用当前方向的更高优先级的服务质量参数/属性代替当前的服务质量参数/属性。
S905：AN设备向SMF网元发送第一方向的信息和更改后的第一方向的业务流的服务质量参数/属性，以进行PDU会话的修改。SMF网元可以进一步通知PCF网元。如果PCF网元没有其他指示，SMF网元更新UE上的服务质量参数/属性。需要注意的是，该步骤S905为可选步骤。
综上所述，该图9所示的实施例中，PCF网元将上行方向的服务质量参数/属性的第一集合和/或下行方向的服务质量参数/属性的第二集合通过SMF网元发送至AN设备，AN设备在获取第一集合或第二集合之后，当确定第一方向的服务质量不满足对应方向的目标服务质量时，可以根据优先级，从第一集合或第二集合中将其它优先级对应的服务质量参数/属性，作为当前方向的服务质量参数/属性，从而可以实现对当前第一方向的服务质量的调整，使得当前第一方向的服务质量尽可能达到对应的目标服务质量。而且由于本申请实施例中根据方向信息，对服务质量的属性/参数进行分组，相比不区分方向的方式，本申请中AN设备可以更高效的对当前方向的服务质量属性/参数进行调整。
