Description

QoS规则的优先级处理方法、设备及存储介质 技术领域
本申请实施例涉及通信技术，尤其涉及一种服务质量(Quality of Service，简称QoS)规则的优先级的处理方法、设备及存储介质。
背景技术
在第五代移动通信(5 Generation，5G)网络中，提出了基于QoS流(QoS flow)的QoS模型。
5G网络中，用户设备(User Equipment，简称UE)可以与5G网络建立一个或者多个分组数据单元(Packet Data Unit，简称PDU)会话(session)，建立PDU Session时或之后，网络设备会为UE建立QoS flow用来承载上、下行数据，网络设备给每个QoS flow配置一个或者多个QoS规则(QoS rule)，每个QoS rule具有一个优先级(Precedence)，每个QoS rule包含一个或多个包过滤器(packet filter)。当UE需要发送上行数据时，UE用数据包的传输层地址，按照QoS rule的优先级的顺序，逐个过滤QoS rule的packet filter，直至找到匹配的packet filter。匹配的packet filter所属的QoS flow就是该上行数据使用的承载，并提供该QoS flow可以保证的服务质量。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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清楚、完整地描述，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。
本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例提供一种QoS规则的优先级的处理方法，本申请实施例的方法可以应用在第五代移动通信(5 Generation，简称5G)网络中，但不限于5G网络中，随着通信系统的演进，本申请的方法还可能应用在未来通信系统中或者下一代移动通信系统中。
5G网络也称为新无线通信系统、新接入技术(New Radio，简称NR)。5G网络包括接入网(access network，简称AN)和核心网。
图1为5G网络架构的一种示意图，如图1所示，5G系统中的接入网可以是无线接入网(radio access  network，简称(R)AN)，5G系统中的(R)AN设备可以由多个5G-(R)AN节点组成，该5G-(R)AN节点可以包括：新空口基站(NR nodeB，简称gNB)、新一代演进型基站(NG-eNB)、中心单元(central unit，简称CU)和分布式单元(distributed unit，简称DU)分离形态的gNB等)、收发点(transmission receive point，简称TRP)、传输点(transmission point，简称TP)、无线保真(WIreless-Fidelity，简称WiFi)网络的接入点(access point，简称AP)或其它节点。
5G网络的核心网包括接入和移动性管理功能(Access and Mobility Management Function，简称AMF)网元、会话管理功能(Session Management Function，简称SMF)网元、用户面功能(User Plane Function，简称UPF)网元、策略控制功能(Policy Control Function，简称PCF)网元、应用功能(Application Function，简称AF)网元、统一数据管理(unified data management，简称UDM)、鉴权服务器功能(Authentication Server Function，简称AUSF)网元、网络切片选择功能(Network Slice Selection Function，进程NSSF)网元等多个功能单元。
AMF网元主要负责移动性管理、接入管理等服务。SMF网元主要负责会话管理、终端设备的地址管理和分配、动态主机配置协议功能、用户面功能的选择和控制等。UPF网元主要负责对外连接到数据网络(data network，简称DN)以及用户面的数据包路由转发、报文过滤、执行QoS控制相关功能等。PCF网元主要负责为网络行为管理提供统一的策略框架、提供控制面功能的策略规则、获取与策略决策相关的注册信息等。AUSF主要负责对终端设备的认证功能等。
需要说明的是，这些功能单元可以独立工作，也可以组合在一起实现某些控制功能，如对终端设备的接入鉴权、安全加密、位置注册等接入控制和移动性管理功能，以及用户面传输路径的建立、释放和更改等会话管理功能。
5G网络中各功能单元之间可以通过下一代网络(next generation，简称NG)接口进行通信，如：终端设备可以通过NG接口1(简称N1)与AMF网元进行控制面消息的传输，(R)AN设备可以通过NG接口3(简称N3)与UPF网元建立用户面数据传输通道，(R)AN设备可以通过NG接口2(简称N2)与AMF网元建立控制面信令连接，UPF网元可以通过NG接口4(简称N4)与SMF网元进行信息交互，AMF网元可以通过NG接口11(简称N11)与SMF网元进行信息交互，SMF网元可以通过NG接口7(简称N7)与PCF网元进行信息交互，UDM网元通过接口8(简称N8)与AMF网元交互，UDM网元通过接口10(简称N10)与SMF网元交互。
需要说明的是，5G网络的核心网的网元除了图1中所示功能单元之外，还可以包括其他功能单元。
本申请实施例涉及到终端设备可以是：手机、电脑，还可以为蜂窝电话、无绳电话、会话发起协议(session initiation protocol，简称SIP)电话、智能电话、个人数字助理(personal digital assistant，简称PDA)、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(set top box，简称STB)、车载设备、可穿戴设备(例如智能手表、智能手环、智能眼镜)、智能家居设备、用于在无线系统上进行通信的其它设备等。
现有技术中，终端设备与网络设备建立QoS流(flow)后，由多个PCF网元为同一个终端设备分配QoS规则(QoS rule)的优先级，各PCF独立为终端设备分配QoS规则的优先级，会导致多个QoS规则的优先级一样，后续，在终端设备根据QoS规则的优先级的顺序确定使用的QoS时，可能会匹配到多个QoS flow，终端设备不知道使用哪个QoS flow，从而导致上行数据无法正常传输。
为了解决现有技术的问题，本申请实施例提供一种QoS规则的优先级的处理方法，由一个网元对终端设备的QoS规则的优先级进行分配，从而能够保证为同一个终端设备的不同QoS规则分配的优先级不重复。或者，为终端设备分配第二QoS规则的优先级的网元，获取终端设备具有的第一QoS规则的优先级信息，在分配第二QoS规则的优先级时，不使用终端设备具有的第一QoS规则的优先级，从而能够保证为同一个终端设备的不同QoS规则分配的优先级不重复。
基于图1所示的网络架构，本申请实施例一提供一种QoS规则的优先级的处理方法，图2为本申请实施例一提供的QoS规则的优先级的处理方法的信令流程图，如图2所示，本实施例提供的方法包括以下步骤：
S101、终端设备向AMF网元发送NAS消息。
第一会话管理请求可以携带在终端设备发送给AMF网元的非接入层(Non-access stratum，简称NAS)消息(message)中。该第一会话管理请求用于请求建立或修改会话，不同于现有技术，本实施例中，该第一会话管理请求消息中包括终端设备具有的第一QoS规则的优先级(precedence)。本申请实施例中，终端设备具有的第一QoS规则的优先级是指：在本次建立或者修改回话之前，终端设备已经具有的QoS规则的优先级，第一QoS规则的优先级可以是终端设备自己或者其他设备为终端设备已分配的QoS规则，优先级信息可以为优先级的索引或者ID。
当第一会话管理请求用于请求建立会话时，该第一会话管理请求也称为第一会话建立请求，当第一 会话管理请求用于请求修改会话时，该第一会话管理请求用于请求修改会话时，该第一会话管理请求也称为第一会话修改请求。
该NAS消息由AN转发给AMF网元，可以理解，由终端设备发送给核心网网元的消息都会经过AN转发，同样，核心网网元发送给终端设备的消息也会经过AN转发。
该NAS消息中还包括待管理的PDU会话的标识(identity，简称ID)和终端设备的ID。当第一会话管理请求用于请求建立会话时，第一会话管理请求例如为PDU Session Establishment Request消息。
其中，第一QoS规则的优先级可以是PCF网元分配的，也可以是终端设备分配。或者，第一QoS规则的优先级中的一部分优先级是PCF网元分配的，另一部分优先级是终端设备分配的。不同于现有技术中，本实施例中，终端设备可以自己为QoS规则分配优先级。
S102、AMF网元向SMF网元发送第二会话管理请求。
AMF网元向SMF网元发送第二会话管理请求可以是调用SMF的UE Context服务，例如：创建，修改等，也可以是一条信令。
第一会话管理请求可以携带在第二会话管理请求中。
AMF网元和SMF网元之间传输的第二会话管理请求可以为Create Session Request消息，本实施例中，AMF网元只是对终端设备发送的第一会话管理请求进行了转发，没有对第一会话管理请求的内容进行处理。
AMF网元向SMF网元发送的第二会话管理请求中包括终端设备的ID。
S103、SMF网元向PCF网元发送第三会话管理请求。
SMF网元接收到第二会话管理请求后，根据第一会话管理请求，向PCF网元发送第三会话管理请求，第三会话管理请求中包括终端设备的ID和第一QoS规则的优先级信息。可选的，第三会话管理请求中还可以包括PDU会话的ID。
其中，第一会话管理请求、第二会话管理请求和第三会话管理请求携带的内容可以相同，但是传输各个消息使用的协议或者接口可能不同，因此，通过第一、第二和第三进行区分。
S104、PCF网元根据第一QoS规则的优先级信息，确定策略控制和计费(Policy Control and Charging，PCC)规则(rule)对应的优先级。
PCF网元在确定PCC规则对应的优先级时，不使用第一QoS规则的优先级，通常情况下，每个PCC规则对应一个优先级。
PCC规则对应的优先级用于确定QoS规则的优先级，因此，通过保证PCC规则对应的优先级在终端设备内的唯一性，可以保证QoS规则的优先级在终端设备内的唯一性。
S105、PCF网元向SMF网元发送第三会话管理请求的响应消息。
该第一会话管理请求的响应消息中包括PCC规则及其对应的优先级，还可以包括QoS参数和服务数据流描述符(Service Data Flow Descriptor)等。
SMF网元接收到PCC规则后，将PCC规则对应的优先级作为第二QoS规则的优先级，第二QoS规则的优先级不同于第一QoS规则的优先级，将PCC规则中的Service Data Flow Descriptor作为QoS规则的包过滤器(Packet Filter)，将PCC规则中的QoS参数作为QoS流描述符(QoS Flow Descriptor)。
如果SMF网元为终端设备新建QoS流，则为该新建的QoS分配QoS流标识(QoS Flow Identifier，简称QFI)，QFI用于该会话内唯一标识一个QoS流。如果SMF网元为终端设备修改QoS流，则不需要分配QFI。
S106、SMF网元向终端设备发送第一会话管理请求的响应消息。
SMF网元通过AMF网元向终端设备发送第一会话管理请求的响应消息，例如，SMF网元向AMF网元发送第二会话管理请求的响应消息，第二会话管理请求的响应消息中包括第一会话管理请求的响应消息，AMF网元将第一会话管理请求的响应消息发送给终端设备。
该第一会话管理请求的响应消息例如为PDU Session Establishment Accept，该第一会话管理请求的响应消息中包括QFI、QoS Flow Descriptor和第二QoS规则，QoS规则中包括第二QoS规则的优先级。
由于本次分配的第二QoS规则的优先级终端设备具有的第一QoS规则的优先级，从而能够保证为同一个终端设备的不同QoS规则分配的优先级不重复。终端设备在进行上行数据发送时，不会匹配到多个优先级相同的QoS规则，从而能够保证上行数据的正常传输。
S107、SMF网元向UPF网元发送第四会话管理请求。
SMF网元将PCC规则转换为包检测规则(Packet Detection Rule)，将Packet Detection Rule携带在第三会话管理请求中发送给UPF网元，以便于UPF网元根据Packet Detection Rule发送下行数据。
可选的，UPF网元可以向SMF网元返回第四会话管理请求的响应消息。
本实施例中，终端设备在会话管理过程中通过向PCF网元上报终端设备具有的第一QoS规则的优 先级，使得PCF网元根据第一QoS规则的优先级信息，确定PCC规则对应的优先级，将PCC规则对应的优先级发送给SMF网元，PCC规则对应的优先级用于确定第二QoS规则的优先级，通过保证PCC规则对应的优先级在终端设备内的唯一性，可以保证QoS规则的优先级在终端设备内的唯一性。因此，即使有多个PCF网元为终端设备分配QoS规则的优先级，也能够保证为同一个终端设备分配的优先级不重复，从而能够保证上行数据的正常传输。
图3为本申请实施例二提供的QoS规则的优先级的处理方法的信令流程图，如图3所示，本实施例提供的方法包括以下步骤：
S201、终端设备向AMF网元发送NAS消息。
NAS消息中包括第一会话管理请求，该第一会话管理请求用于请求建立或者修改会话。该NAS消息中还可以包括待管理的PDU会话的ID、终端设备的ID。
不同于实施例一的方案，该第一会话管理请求中不包括终端设备具有的第一QoS规则的优先级信息。
S202、AMF网元向SMF网元发送第二会话管理请求。
第一会话管理请求可以携带在第二会话管理请求中，该第二会话管理请求中包括终端设备的ID。
S203、SMF网元向PCF网元发送第三会话管理请求。
SMF网元接收到第二会话管理请求后，向PCF网元发送第三会话管理请求，该第三会话管理请求中包括终端设备的ID。
S204、PCF网元向SMF网元发送第三会话管理请求的响应消息。
第三会话管理请求的响应消息中包括PCC规则，该PCC规则中包括QoS参数和Service Data Flow Descriptor。
不同于实施例一，该PCC规则中不包括PCC规则对应的优先级，或者SMF忽略PCC规则中的优先级。
S205、SMF网元向AMF网元发送优先级分配请求。
优先级分配请求用于请求AMF网元为终端设备分配第二QoS规则的优先级，该优先级分配请求包括终端设备的ID和请求分配的优先级个数，请求分配的优先级个数与QoS规则的个数相同。
S206、AMF网元向SMF网元发送优先级分配请求的响应消息。
AMF网元接收到优先级分配请求后，根据优先级分配请求为终端设备分配第二QoS规则的优先级，对于一个终端设备来说，只关联一个AMF网元，即终端设备和AMF网元是一一对应关系。
因此，该终端设备的所有QoS规则的优先级都由该AMF网元分配，该AMF网元上存储有该终端设备的第一QoS规则的优先级信息，从而能够在为该终端设备分配第二QoS规则的优先级时，不使用第一QoS规则的优先级，从而保证第二QoS规则的优先级不同于第一QoS规则的优先级。
或者，该AMF网元的分配规则能够保证分配给同一个终端设备的QoS规则的优先级不重复。
AMF网元将为终端设备分配的第二QoS规则的优先级信息携带在优先级分配请求的响应消息中发送给SMF网元。
S207、SMF网元向终端设备发送第一会话管理请求的响应消息。
SMF网元将优先级分配响应中包括的优先级作为第二QoS规则的优先级，将PCC规则中的Service Data Flow Descriptor作为QoS规则的Packet Filter，将PCC规则中的QoS参数作为QoS Flow Descriptor。如果SMF网元为终端设备新建了QoS流，则为该新建的QoS分配QFI。
SMF网元通过AMF网元向终端设备发送第一会话管理请求的响应消息，该第一会话管理请求的响应消息例如为PDU Session Establishment Accept，该第一会话管理请求的响应消息中包括QFI、QoS Flow Descriptor和第二QoS规则，第二QoS规则中包括第二QoS规则的优先级。
S208、SMF网元向UPF网元发送第四会话管理请求。
SMF网元将QoS规则转换为Packet Detection Rule，将Packet Detection Rule携带在第四会话管理请求中发送给UPF网元，以便于UPF网元根据Packet Detection Rule发送下行数据。
本实施例中，SMF网元接收到终端设备发送的第一会话管理请求后，从PCF网元获取PCC规则，在获取到PCC规则后向AMF网元发送优先级分配请求，AMF网元为终端设备分配第二QoS规则的优先级，并将第二QoS规则的优先级信息携带在优先级分配请求的响应消息中发送给SMF网元，其中，第二QoS规则的优先级不同于终端设备具有的第一QoS规则的优先级。该方式中，由AMF网元统一为终端设备的QoS规则分配优先级，使得分配给同一个终端设备的QoS规则的优先级不重复，从而能够保证上行数据的正常传输。
图4为本申请实施例三提供的QoS规则的优先级的处理方法的信令流程图，如图4所示，本实施例提供的方法包括以下步骤：
S301、终端设备向AMF网元发送NAS消息。
NAS消息中包括第一会话管理请求。
S302、AMF网元向SMF网元发送第二会话管理请求。
S303、SMF网元向PCF网元发送第三会话管理请求。
步骤S301-S303的实现方式与实施例二中步骤S201-S203相同，这里不再赘述。
S304、PCF网元向用户数据存储(User Data Repository，简称UDR)网元发送查询请求(query request)。
UDR网元用于存储终端设备的用户数据，该用户数据包括终端设备具有的第一QoS规则的优先级，UDR网元可以将终端设备的ID作为QoS规则的优先级的索引，建立二者的对应关系。
该查询请求用于向UDR网元请求第一QoS规则的优先级信息，该查询请求中包括终端设备的ID，UDR网元根据终端设备的ID查询得到终端设备的第一QoS规则的优先级。
S305、UDR网元向PCF网元发送查询请求的响应消息，该查询请求的响应消息中包括终端设备具有的第一QoS规则的优先级信息。
UDR网元接收到查询请求后，根据终端设备的标识查询第一QoS规则的优先级信息，将第一QoS规则的优先级信息携带在查询请求的响应消息中发送给UDR网元。
S306、PCF网元根据第一QoS规则的优先级信息，确定PCC规则对应的优先级。
PCF网元在确定PCC规则对应的优先级时，不使用第一QoS规则的优先级，PCC规则对应的优先级用于确定QoS规则的优先级性。
S307、PCF网元向SMF网元发送第三会话管理请求的响应消息。
该第三会话管理请求的响应消息中包括PCC规则及其对应的优先级，还可以包括QoS参数和Service Data Flow Descriptor等。
SMF网元接收到PCC规则后，将PCC规则对应的优先级作为第二QoS规则的优先级，第二QoS规则的优先级不同于第一QoS规则的优先级，将PCC规则中的Service Data Flow Descriptor作为QoS规则的Packet Filter，将PCC规则中的QoS参数作为QoS Flow Descriptor。
如果SMF网元为终端设备新建QoS流，则为该新建的QoS分配QFI。如果SMF网元为终端设备修改QoS流，则不需要分配QFI。
S308、SMF网元向终端设备发送第一会话管理请求的响应消息。
SMF网元通过AMF网元向终端设备发送第一会话管理请求的响应消息，该第一会话管理请求的响应消息例如为PDU Session Establishment Accept，该第一会话管理请求的响应消息中包括QFI、QoS Flow Descriptor和第二QoS规则，第二QoS规则中包括第二QoS规则的优先级。
由于每次终端设备分配的第二QoS规则的优先级不同于终端设备具有的第一QoS规则的优先级，从而能够保证为同一个终端设备的不同QoS规则分配的优先级不重复。终端设备在进行上行数据发送时，不会匹配到多个优先级相同的QoS规则，从而能够保证上行数据的正常传输。
S309、SMF网元向UPF网元发送第四会话管理请求。
SMF网元将QoS规则转换为Packet Detection Rule，将Packet Detection Rule携带在第四会话管理请求中发送给UPF网元，以便于UPF网元根据Packet Detection Rule发送下行数据。
S310、PCF网元向UDR网元发送更新请求。
该更新请求用于请求更新UDR网元上存储的终端设备具有的第一QoS规则的优先级，该更新请求中包括终端设备的ID以及PCC规则对应的优先级信息。
S311、UDR网元根据更新请求，更新第一QoS规则的优先级。
UDR网元接收到该更新请求后，将该更新请求中包括的PCC规则对应的优先级作为待更新的QoS规则的优先级，更新本地保存的第一QoS规则的优先级。从而能够保证该PCF网元或者终端设备对应的其他PCF网元，每次从UDR网元请求到的数据为最新数据。
本实施例中，PCF网元接收到SMF网元发送的第三会话管理请求后，向UDR网元发送查询请求，查询请求用于请求查询终端设备具有的第一QoS规则的优先级信息，PCF网元根据第一QoS规则的优先级信息，确定PCC规则对应的优先级，将PCC规则对应的优先级发送给SMF网元，PCC规则对应的优先级用于确定第二QoS规则的优先级，通过保证PCC规则对应的优先级在终端设备内的唯一性，可以保证QoS规则的优先级在终端设备内的唯一性。因此，即使有多个PCF网元，也能够保证为同一个终端设备分配的优先级不重复，从而能够保证上行数据的正常传输。
实施例三中，由PCF网元向UDR网元请求第一QoS规则的优先级。在本申请其他实施例中，S302之后，也可以由SMF网元根据第一会话管理请求，向UDR网元发送查询请求，查询请求中包括终端设备的标识，SMF网元接收UDR网元发送的查询请求的响应消息，查询请求的响应消息中包括第一QoS规则的优先级信息。
SMF网元在从UDR网元获取到第一QoS规则的优先级信息后，向PCF网元发送第三会话管理请求消息，该第三会话管理请求中包括第一QoS规则的优先级信息，后续步骤参照步骤S306-S311，这里不再赘述。
图5为本申请实施例四提供的QoS规则的优先级的处理方法的信令流程图，如图5所示，本实施例提供的方法包括以下步骤：
S401、终端设备向AMF网元发送NAS消息。
NAS消息中包括第一会话管理请求。
S402、AMF网元向SMF网元发送第二会话管理请求。
S403、SMF网元向第一PCF网元发送第三会话管理请求。
步骤S401-S403的实现方式与实施例二中步骤S201-S203相同，这里不再赘述。
S404、第一PCF网元根据终端设备具有的QoS规则的优先级信息，确定PCC规则对应的优先级。
其中，该第一QoS规则的优先级信息是UDR网元，在终端设备的QoS规则的优先级被更新后向第一PCF网元发送的。
第一PCF网元在确定PCC规则对应的优先级时，不使用第一QoS规则的优先级，PCC规则对应的优先级用于确定QoS规则的优先级性。
S405、第一PCF网元向SMF网元发送第三会话管理请求的响应消息。
S406、SMF网元向终端设备发送第一会话管理请求的响应消息。
S407、SMF网元向UPF网元发送第四会话管理请求。
S408、第一PCF网元向UDR网元发送第一更新请求。
该第一更新请求用于请求更新UDR网元上存储的终端设备的第一QoS规则的优先级，该第一更新请求中包括终端设备的ID以及PCC规则对应的优先级信息。
S409、UDR网元根据第一更新请求，更新第一QoS规则的优先级。
UDR网元接收到该第一更新请求后，将第一更新请求中包括的PCC规则对应的优先级作为待更新的QoS规则的优先级，更新本地保存的终端设备具有的第一QoS规则的优先级。
例如，为终端设备新分配了三个QoS规则的优先级，则UDR网元将新分配的三个QoS规则的优先级与本地保存的终端设备的第一QoS规则的优先级进行合并。
S410、UDR网元向第二PCF网元发送第二更新请求，该第二更新请求中包括待更新的QoS规则的优先级信息。
本实施例中，第一PCF网元和第二PCF网元都是终端设备对应的PCF网元，一个终端设备通常对应多个PCF网元，当第一PCF网元为终端设备分配了优先级时，将分配的优先级更新到UDR网元，UDR网元将分配的优先级同步给终端设备对应的其他PCF网元。从而保证终端设备对应的所有PCF上存储的为终端设备已分配的QoS规则的优先级为最新数据。
UDR网元可以只将待更新的QoS规则的优先级信息发送给第二PCF网元，例如，新增了三个优先级，则至将该三个优先级信息发送给第二PCF。
UDR网元也可以将第一QoS规则的优先级都发送给第二PCF网元，第二PCF网元接收到第二更新请求后，将第二更新请求中包括的第一QoS规则的优先级，替换本地保存的第一QoS规则的优先级。
本实施例与实施例三的区别点为：第一PCF网元接收到第二会话管理请求后，不需要向UDR网元查询为第一QoS规则的优先级。本实施例中，第一QoS规则的优先级由UDR网元预先发送给第一PCF网元，从而节省了PCF网元向UDR网元查询第一QoS规则的优先级的时间和信令开销，加快了优先级的分配效率。
本实施例中，UDR网元上的终端设备的优先级信息被更新后，UDR网元会同步给终端设备对应的所有PCF网元，从而保证终端设备对应的所有PCF上存储的第一QoS规则的优先级为最新数据，各PCF网元都不需要向UDR网元请求第一QoS规则的优先级，节省了时间和信令开销。
需要说明的是，在本发明其他实施例中，UDR网元也可以为一个PCF网元，该PCF网元用于对终端设备的QoS规则的优先级进行统一管理，该PCF网元上存储有终端设备具有的第一QoS规则的优先级，具体分配流程与实施例三和实施例四相同，这里不再赘述。该用于对终端设备的QoS规则的优先级进行统一管理的PCF网元也称为高位PCF网元、管理PCF网元或者第二PCF网元。
上述实施例中，由终端设备向SMF发送第一会话管理请求，以触发SMF网元从第一网元获取终端设备的第二QoS规则的优先级。在本申请可能的实现方式中，也可以由其他核心网网元触发SMF网元从第一网元获取终端设备的第二QoS规则的优先级。
一种示例性的方式中，该第一网元为PCF网元，PCF网元向SMF网元发送PCC规则的更新消息，SMF网元将更新后的PCC规则的优先级作为第二QoS规则的优先级，并将第二QoS规则的优先级信 息发送给终端设备。
另一种示例性的方式中，SMF网元接收核心网网元发送的指示消息，该指示消息用于指示为终端设备修改或者分配QoS规则的优先级，SMF网元根据该指示消息，从第一网元获取第二QoS规则的优先级。
当第一网元为AMF网元时，SMF网元根据该指示消息，向AMF网元请求为终端设备分配第二QoS规则的优先级，分配流程参照实施例二的描述，这里不再赘述。
当第一网元为PCF网元时，SMF网元请求PCF网元为终端设备分配第二QoS规则的优先级，分配流程参照实施例一、实施例三和实施例四的描述，这里不再赘述。
图6为本申请实施例五提供的QoS规则的优先级的处理方法的信令流程图，如图6所示，本实施例提供的方法包括以下步骤：
S501、终端设备向AMF网元发送NAS消息。
NAS消息中包括第一会话管理请求。
S502、AMF网元向SMF网元发送第二会话管理请求。
S503、SMF网元向PCF网元发送第三会话管理请求。
SMF网元接收到第二会话管理请求后，向PCF网元发送第三会话管理请求，该第三会话管理请求中包括终端设备的ID。
S501-S503参照实施例二中步骤S201-203的描述，这里不再赘述。
S504、PCF网元向UDR网元发送优先级分配请求。
该优先级分配请求用于请求AMF网元为终端设备分配第二QoS规则的优先级，该优先级分配请求中包括终端设备的标识和请求分配的优先级个数。
S505、UDR网元根据优先级分配请求，为终端设备分配第二QoS规则的优先级。
该方式中由UDR网元统一为网络中的终端设备分配QoS规则的优先级，UDR网元根据优先级分配请求中包括的请求分配的优先级个数，为终端设备分配相应个数的第二QoS规则的优先级。
该UDR网元上存储有该终端设备具有的第一QoS规则的优先级信息，能够在为该终端设备分配第二QoS规则的优先级时，不使用第一QoS规则的优先级，从而保证分配的第二QoS规则的优先级不同于终端设备具有的第一QoS规则的优先级。或者，该UDR网元的分配规则能够保证分配给同一个终端设备的QoS规则的优先级不重复。
S506、UDR网元向PCF网元发送优先级分配请求的响应消息。
优先级分配请求的响应消息中包括为终端设备分配的第二QoS规则的优先级信息。
S507、PCF网元向SMF网元发送第三会话管理请求的响应消息。
第三会话管理请求的响应消息中包括PCC规则和第二QoS规则的优先级信息，该PCC规则中包括QoS参数和Service Data Flow Descriptor。该PCC规则中不包括PCC规则对应的优先级，或者SMF忽略PCC规则中的优先级。
S508、SMF网元向终端设备发送第一会话管理请求的响应消息。
SMF网元将第三会话管理请求的响应消息中包括的QoS优先级作为第二QoS规则的优先级，将PCC规则中的Service Data Flow Descriptor作为QoS规则的Packet Filter，将PCC规则中的QoS参数作为QoS Flow Descriptor。如果SMF网元为终端设备新建了QoS流，则为该新建的QoS分配QFI。
S509、SMF网元向UPF网元发送第四会话管理请求。
SMF网元将QoS规则转换为Packet Detection Rule，将Packet Detection Rule携带在第四会话管理请求中发送给UPF网元，以便于UPF网元根据Packet Detection Rule发送下行数据。
本实施例中，PCF网元接收到第三会话管理请求之后，向UDR网元发送优先级分配请求，UDR网元根据优先级分配请求，为终端设备分配第二QoS规则的优先级，UDR网元将为终端设备分配的第二QoS规则的优先级信息携带在优先级分配请求的响应消息发送给PCF网元，第二QoS规则的优先级不同于终端设备具有的第一QoS规则的优先级。该方式中，由UDR网元统一为终端设备的QoS规则分配优先级，使得分配给同一个终端设备的QoS规则的优先级不重复，从而能够保证上行数据的正常传输。
