Description

报告信息的发送方法和通信装置以及通信系统
本申请要求于2020年1月23日提交中国专利局、申请号为2020010077131.5、发明名称为“报告信息的发送方法和通信装置以及通信系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及报告信息的发送方法和通信装置以及通信系统。
背景技术
在第五代移动通信系统(5th generation wireless systems，5G)中，用户设备(user equipment，UE)接入网络后建立协议数据单元(protocol data unit，PDU)会话，并通过PDU会话访问外部的数据网络(data network，DN)，与部署在DN中的应用服务器交互。根据用户访问的DN不同，会话管理功能(session management function，SMF)可以选择接入DN的用户面功能(user plane function，UPF)，并通过UPF访问应用服务器。同一个应用的应用服务器可以部署在多个位置，SMF能够根据UE的接入位置选择靠近UE同时又能支持UE访问DN的UPF，以便减少路由迂回，降低网络延迟。通常，这些应用服务器可部署在移动边缘计算(mobile edge compute，MEC)环境中。应用需要感知到业务数据流传输路径的服务质量(quality of service，QoS)信息，以便在应用层执行相应的调整。
目前，应用可以通过如下方式获取QoS信息：应用功能(application function，AF)向网络能力开放功能(network exposure function，NEF)发送QoS控制通知(control notification)请求，Qos控制通知请求用于请求获取业务数据流传输的QoS信息，NEF将Qos控制通知请求发送给策略控制功能(policy control function，PCF)。PCF接收到Qos控制通知请求之后，制定相应的QoS策略并将该QoS策略发送给SMF。SMF执行QoS策略并生成执行结果，SMF通过接入和移动性管理功能(access and mobility management function，AMF)向无线接入网(radio access network，RAN)发送执行结果。RAN可以根据该执行结果对QoS流(flow)进行判断以生成QoS信息，例如RAN判断QoS流的保障流比特速率(guaranteed flow bit rate，GFBR)不能保证时，RAN通过如下路径发送GFBR无法保证的通知：RAN->AMF->SMF->PCF->NEF->AF，最终才能使得AF接收到GFBR无法保证的通知，AF接收到该通知后可以在应用层执行相应的调整。
通过对QoS信息的获取方式的说明可知，需要通过“RAN->AMF->SMF->PCF->NEF->AF”复杂路径才能完成RAN与AF的通信，该路径太长，对于时间敏感性较高的业务，QoS信息的时效性差，使得AF在应用层做出调整时存在较大时延。
发明内容

在一种可能的实现方式中，所述方法还包括：所述第一会话管理网元接收来自所述第二接入网网元的所述第一QoS Flow对应的第二候选QoS文档的标识；其中，所述第三报告信息还包括第二候选业务需求的标识，所述第二候选业务需求的标识对应所述第二候选QoS文档的标识。在上述方案中，第一QoS Flow的QoS需求不能得到保障时，第二接入网网元还可以向第一会话管理网元发送第一QoS Flow对应的第二候选QoS文档的标识，第二候选QoS文档也是满足第一Qos Flow的QoS需求的候选QoS文档。此时，第一会话管理网元还可以确定出满足第一Qos Flow的QoS需求的第二候选QoS文档，第一会话管理网元根据候选QoS文档和候选业务需求的对应关系可以确定出第二候选QoS文档的标识对应的第二候选业务需求的标识。第一会话管理网元向应用功能网元发送第三报告信息，第三报告信息除了包括第三指示信息，第三报告信息还包括第二候选业务需求的标识，从而使得应用功能网元可以获取到满足第一Qos Flow的QoS需求的第二候选QoS文档，解决了存在多个候选QoS文档时的报告指示问题。
在一种可能的实现方式中，所述第二报告信息还包括所述第一业务数据流的标识信息。在上述方案中，应用功能网元可以从第一会话管理网元接收到第二报告信息，若应用功能网元提供多个业务数据流的描述信息，例如存在第一业务数据流和第二业务数据流的QoS需求能否得到保障的指示时，在第一会话管理网元发送的第二报告信息中需要携带第一业务数据流的标识信息和第二业务数据流的标识信息，本申请实施例中第一会话管理网元向应用功能网元发送的报告信息中携带业务数据流的标识信息，解决了存在多个业务数据流时指示每个业务流的QoS需求能否得到保障的指示问题。
在一种可能的实现方式中，所述第三报告信息还包括所述第一业务数据流的标识信息。在上述方案中，应用功能网元可以从第一会话管理网元接收到第三报告信息，若应用功能网元提供多个业务数据流的描述信息，例如存在第一业务数据流和第二业务数据流的QoS需求能否得到保障的指示时，在第一会话管理网元发送的第三报告信息中需要携带第一业务数据流的标识信息和第二业务数据流的标识信息，本申请实施例中第一会话管理网元向应用功能网元发送的报告信息中携带业务数据流的标识信息，解决了存在多个业务数据流时指示每个业务流的QoS需求能否得到保障的指示问题。

在一种可能的实现方式中，所述第二指示信息根据所述第一指示信息确定。在上述方案中，第二指示信息是根据第一指示信息携带的指示内容生成的，第一指示信息指示第一QoS Flow的QoS需求不能得到保障，第一会话管理网元根据第一QoS Flow的QoS需求不能得到保障确定第一QoS Flow传输的第一业务数据流的QoS需求不能得到保障，在第二指示信息中携带第一业务数据流的QoS需求不能得到保障。

在一种可能的实现方式中，当所述第一会话管理网元为中间会话管理网元时，所述第 一会话管理网元接收来自用户面网元的第一报告信息之前，所述方法还包括：第二会话管理网元向所述第一会话管理网元发送第一策略，所述第一策略包括所述第一QoS Flow的标识、第一QoS通知控制指示信息、至少一个候选QoS文档、所述应用功能网元的通知端点的信息以及所述至少一个候选QoS文档的标识对应的至少一个候选业务需求的标识，其中，所述至少一个候选QoS文档包括所述第一候选QoS文档，所述至少一个候选业务需求的标识包括所述第一候选业务需求的标识，所述第一QoS通知控制指示信息用于指示发送所述第一QoS Flow的QoS需求能否得到保障的指示信息；所述第一会话管理网元接收来自所述第二会话管理网元的所述第一策略；所述第一会话管理网元根据所述第一策略确定第三策略，并向所述用户面网元发送所述第三策略，所述第三策略用于指示所述用户面网元发送所述第一QoS Flow的QoS需求能否得到保障的指示信息；所述用户面网元接收所述第三策略。在上述方案中，用户面网元可以和第一会话管理网元进行通信，从第一会话管理网元接收到第三策略，用户面网元解析该第三策略，用户面网元按照第三策略的指示，需要发送第一QoS Flow的QoS需求能否得到保障的指示信息，例如用户面网元在确定第一QoS Flow的QoS需求不能得到保障时，发送前述的携带第一指示信息的第一报告信息，实现了第一报告信息的快速上报。
在一种可能的实现方式中，所述第一会话管理网元根据所述第一报告信息向应用功能网元发送第二报告信息，包括：当所述第一指示信息包括所述第一QoS Flow的标识时，所述第一会话管理网元根据所述第一QoS Flow的标识确定所述应用功能网元的通知端点，并通过所述应用功能网元的通知端点向所述应用功能网元发送所述第二报告信息。在上述方案中，第一会话管理网元接收到第一策略之后，第一会话管理网元解析该第一策略，可以获取到第一QoS Flow的标识和应用功能网元的通知端点的信息，第一会话管理网元根据第一指示信息中携带的第一QoS Flow的标识确定第一策略中携带的应用功能网元的通知端点，并向该通知端点发送第二报告信息，从而应用功能网元可以接收到来自第一会话管理网元的第二报告信息。本申请实施例中，第一会话管理网元可以通过应用功能网元的通知端点向应用功能网元发送第二报告信息，从而实现了第一会话管理网元和应用功能网元之间的通信，使得应用功能网元可以快速的接收到第二报告信息，并根据第二报告信息进行应用层的调整，降低了第二报告信息的传输时延。

基于图1所示的通信系统可知，应用功能网元可以和第一会话管理网元进行通信，例如应用功能网元可以从第一会话管理网元接收到第二报告信息，应用功能网元解析该第二报告信息，通过该第二报告信息获取到第二指示信息和第一候选业务需求的标识，应用功能网元进一步的解析第二指示信息，应用功能网元可以获取到第一业务数据流的QoS需求不能得到保障。应用功能网元还从第二报告信息中获取到了第一候选业务需求的标识，从而使得应用功能网元还可以确定出候选业务需求，以便于应用功能网元在确定第一业务数据流的QoS需求不能得到保障时根据第一候选业务需求在应用层快速调整。因此极大地缩短了指示第一业务数据流的QoS需求不能得到保障的路径，对于时间敏感性较高的业务，第二报告信息的时效性高，降低了应用功能网元在应用层做出调整时的时延。
在前述的实施例中，第一会话管理网元接收来自第二会话管理网元的第一策略，该第一策略中包括有应用功能网元的通知端点的信息。具体的，步骤304第一会话管理网元根据第一报告信息向应用功能网元发送第二报告信息，包括：

当第一指示信息包括第一QoS Flow的标识时，第一会话管理网元根据第一QoS Flow的标识确定本地网络能力开放网元的通知端点，并通过本地网络能力开放网元的通知端点向本地网络能力开放网元发送第二报告信息，第二报告信息由本地网络能力开放网元向应用功能网元发送。
其中，第一会话管理网元接收到第一策略之后，第一会话管理网元解析该第一策略，可以获取到第一QoS Flow的标识和本地网络能力开放网元的通知端点的信息，第一会话管理网元根据第一指示信息中携带的第一QoS Flow的标识确定第一策略中携带的本地网络能力开放网元的通知端点，并向该通知端点发送第二报告信息，从而本地网络能力开放网元可以接收到来自第一会话管理网元的第二报告信息，本地网络能力开放网元向应用功能网元发送该第二报告信息。本申请实施例中，第一会话管理网元可以通过本地网络能力开放网元的通知端点向本地网络能力开放网元发送第二报告信息，再由本地网络能力开放网元 向应用功能网元发送该第二报告信息，从而实现了第一会话管理网元和应用功能网元之间的通信，使得应用功能网元可以快速的接收到第二报告信息，并根据第二报告信息进行应用层的调整，降低了第二报告信息的传输时延。
在本申请的一些实施例中，终端设备还可以进行切换，例如终端设备从第一接入网网元切换至第二接入网网元，其中，第一接入网网元可以是终端设备切换之前所在的无线接入网，第二接入网网元可以是终端设备切换之后所在的无线接入网。步骤304第一会话管理网元向应用功能网元发送第二报告信息之后，本申请实施例提供的报告信息的发送方法还包括如下步骤：
当终端设备从第一接入网网元切换至第二接入网网元时，第一会话管理网元接收来自第二接入网网元的QoS Flow的标识信息，QoS Flow的标识信息包括第一QoS Flow的标识；
第一会话管理网元向应用功能网元发送第三报告信息，其中，第三报告信息包括第三指示信息，第三指示信息用于指示第一业务数据流的QoS需求不能得到保障。
其中，终端设备从第一接入网网元切换至第二接入网网元时，第二接入网网元还可以向第一会话管理网元发送QoS Flow的标识信息，例如第二接入网网元和AMF之间建立有N2接口，AMF和第一会话管理网元之间建立有N11接口，第一会话管理网元接收来自第二接入网网元的QoS Flow的标识信息，QoS Flow的标识信息包括第一QoS Flow的标识，第一QoS Flow用于传输第一业务数据流。第一会话管理网元可以向应用功能网元发送第三报告信息，其中，第三报告信息包括第三指示信息，第三指示信息用于指示第一业务数据流的QoS需求不能得到保障。本申请实施例中在终端设备发生切换时，应用功能网元也可以从第一会话管理网元接收到第三报告信息，并根据第三报告信息进行应用层的调整，降低了第三报告信息的传输时延。
在本申请的一些实施例中，终端设备还可以进行切换，例如终端设备从第一接入网网元切换至第二接入网网元，其中，第一接入网网元可以是终端设备切换之前所在的无线接入网，第二接入网网元可以是终端设备切换之后所在的无线接入网。本申请实施例提供的报告信息的发送方法还包括如下步骤：
第一会话管理网元接收来自第二接入网网元的第一QoS Flow对应的第二候选QoS文档的标识；
其中，第三报告信息还包括第二候选业务需求的标识，第二候选业务需求的标识对应第二候选QoS文档的标识。
具体的，第一QoS Flow的QoS需求不能得到保障时，第二接入网网元还可以向第一会话管理网元发送第一QoS Flow对应的第二候选QoS文档的标识，第二候选QoS文档也是满足第一Qos Flow的QoS需求的候选QoS文档。此时，第一会话管理网元还可以确定出满足第一Qos Flow的QoS需求的第二候选QoS文档，第一会话管理网元根据候选QoS文档和候选业务需求的对应关系可以确定出第二候选QoS文档的标识对应的第二候选业务需求的标识。第一会话管理网元向应用功能网元发送第三报告信息，第三报告信息除了包括第三指示信息，第三报告信息还包括第二候选业务需求的标识，从而使得应用功能网元可以获取到满足第一Qos Flow的QoS需求的第二候选QoS文档，解决了存在多个候选QoS文档时的报告指示问题。
在本申请的一些实施例中，第二报告信息还包括第一业务数据流的标识信息。
在本申请的一些实施例中，第三报告信息还包括第一业务数据流的标识信息。
其中，应用功能网元可以从第一会话管理网元接收到第二报告信息，或者接收到第三报告信息，若应用功能网元提供多个业务数据流的描述信息，例如存在第一业务数据流和第二业务数据流的QoS需求能否得到保障的指示时，在第一会话管理网元发送的第二报告信息和第三报告信息中需要携带第一业务数据流的标识信息和第二业务数据流的标识信息，本申请实施例中第一会话管理网元向应用功能网元发送的报告信息中携带业务数据流的标识信息，解决了存在多个业务数据流时指示每个业务流的QoS需求能否得到保障的指示问题。
通过前述实施例对本申请的举例说明可知，第一会话管理网元接收来自用户面网元的第一报告信息，第一报告信息包括第一指示信息和第一候选QoS文档的标识，第一指示信息用于指示第一QoS Flow的QoS需求不能得到保障；第一会话管理网元向应用功能网元发送第二报告信息，其中，第二报告信息包括第二指示信息和第一候选业务需求的标识，第一候选业务需求的标识对应第一候选QoS文档的标识，第二指示信息用于指示第一业务数据流的QoS需求不能得到保障,第一QoS Flow用于传输第一业务数据流，业务数据流是应用功能网元对应的应用的业务数据流。由于第一会话管理网元可以从用户面网元接收到第一报告信息，该第一报告信息中携带第一指示信息和第一QoS文档的标识，因此第一会话管理网元可以根据第一指示信息获取第二指示信息，还可以根据第一候选QoS文档的标识确定第一候选业务需求的标识，因此第一会话管理网元可以生成第二报告信息，第一会话管理网元向应用功能管理网元发送的第二报告信息，通过该第二报告信息中的第二指示信息指示第一业务数据流的QoS需求不能得到保障。本申请实施例中基于“用户面网元-第一会话管理网元-应用功能网元”路径可以使得应用功能网元确定第一业务数据流的QoS需求不能得到保障，另外第二报告信息中还携带第一候选业务需求的标识，从而使得应用功能网元还可以确定出候选业务需求，以便于应用功能网元在确定第一业务数据流的QoS需求不能得到保障时根据第一候选业务需求在应用层快速调整。因此极大地缩短了指示第一业务数据流的QoS需求不能得到保障的路径，对于时间敏感性较高的业务，第二报告信息的时效性高，降低了应用功能网元在应用层做出调整时的时延。
为便于更好的理解和实施本申请实施例的上述方案，下面举例相应的应用场景来进行具体说明。
基于图1所示的通信系统，接下来对通信系统的不同应用场景进行举例说明，例如图4a至图4c为图1所示的通信系统的三种具体应用场景。后续实施例中以第一会话管理网元为I-SMF、用户面网元为Local PSA、应用功能网元为AF进行示例说明。

图4a至图4c为本申请实施例提供的下一代移动网络的架构示意图，本申请实施例可用于下一代移动网络架构，接下来对本申请实施例涉及的主要网元进行如下说明：
RAN用于实现无线有关的功能；
接入和移动性管理功能(access and mobility management function，AMF)负责用户的移动性管理，包括移动状态管理，分配用户临时身份标识，认证和授权用户。
SMF负责UPF网元选择，UPF网元重选，IP地址分配，负责承载的建立、修改和释放，QoS控制。具体可以在核心数据中心中部署SMF，在本地数据中心中部署I-SMF。
UPF可以部署在本地数据中心，例如UPF可以是Local PSA。UPF支持以下全部或者部分功能：将PDU会话与数据网络互连；分组路由和转发；数据包检测。
策略控制功能(policy control function，PCF)包含策略控制决策和基于流计费控制的功能，包含用户签约数据管理功能，策略控制功能，计费策略控制功能，QoS控制等等。
应用服务(application function，AF)向UE提供某种应用层服务，AF在向UE提供服务时，对服务质量QoS策略(Policy)和计费策略(Charging)有要求，且需要通知网络。同时，AF也需要核心网反馈的应用相关的信息。例如AF可以部署在EAS中。
网络能力开放功能(network exposure function，NEF)主要支持网络能力开放功能，对外开放网络能力和服务，3GPP网络功能(Network Function，NF)通过NEF向其他NF发布功能和事件。NF开放的能力和事件可以安全地开放给第三方应用。具体可以在核心数据中心中部署NEF，在本地数据中心中部署Local NEF。
如下以图5和图6所示的实施例分别介绍本申请实施例提供的技术方案。本申请实施例中，PCF根据应用功能网元标识(AF Id)、通知端点或本地报告指示确定在PCC规则中 携带通知端点、QoS Notification Control信息、Alternative QoS参数集(Parameter Set)以及AltQosId和AltSerId对应关系，其中，每个Alternative QoS参数集包括一个AltQosId和对应的候选参数。QoS Notification Control信息用于指示需要RAN发送QoS需求能否保障的通知。SMF向I-SMF发送通知端点对应的QoS Notification Control信息、本地报告指示、Alternative QoS Profile以及AltProId和AltSerId对应关系。SMF向Local PSA发送QoS Notification Control事件检测信息，用于检测事件报告的数据包信息进行延迟测量。当gNodeB检测到QoS Notification Control事件，向PSA发送用户面数据包，数据包中携带服务质量流标识(QFI)和QoS Notification Control事件、AltProId。Local PSA再通知I-SMF。I-SMF执行AltProId到AltSerId的映射。在跨gNodeB切换过程中，I-SMF根据接受的QoS Flow列表，判断之前不能保障QoS需求的QoS Flow在这个列表中，则I-SMF判断这个QoS Flow的QoS需求能够再次得到保障，于是向Local NEF或AF发送QoS需求能够得到保障的通知。通过上述交互方式，能够将QoS通知控制(Notification Control)事件高效的发送给应用功能网元，降低了传输时延。
本申请实施例基于图4a至图4c所述的通信系统架构，AF通过Local NEF或直接通过NEF请求事件检测，例如事件可以是QoS Notificaiton control事件。针对QoS Notification Control事件，RAN通过用户面将检测到的QoS Notification Control事件报告发送给Local PSA，Local PSA再发送给I-SMF，而I-SMF直接发送给AF或Local NEF。如图5所示，主要包括如下交互流程：
S501、UE和Local建立PDU会话。
gNodeB保存Local PSA由于接受上行数据包的核心网隧道信息(CN Tunnel Info)，其中，CN Tunnel Info通常包括接收上行数据的IP地址和隧道标识(TEID)。
S502、若本地没有部署Local NEF，则AF向NEF发送服务质量创建请求消息，例如该服务质量创建请求消息可以是Nnef_AFsessionWithQoS_Create request消息，Nnef_AFsessionWithQoS_Create request消息中包括应用功能网元标识(AF Id)、UE地址、请求的业务信息(例如业务信息包括业务数据流描述信息、业务的QoS需求)、事件标识(例如事件标识可以是QoS Notification Control事件的标识)和通知端点(Notification Endpoint1a)。Notification Endpoint1a包括接收事件通知的目标通知地址Notification Target Address1a或是Notification Target Address1a和Notification Correlation Id1a。AF可以提供多个业务数据流的描述信息，并用数据流标识进行标识。
若本地部署Local NEF，则AF向Local NEF发送Nnef_AFsessionWithQoS_Create request消息，Nnef_AFsessionWithQoS_Create request消息中包括AF Id、UE地址、事件标识(例如事件标识可以是QoS Notification Control事件的标识)和通知端点Notification Endpoint1a。Notification Endpoint1a包括接收事件通知的目标通知地址Notification Target Address1a，或是Notification Target Address1a和Notification Correlation Id1a。Local NEF确定Notification Endpoint1b，保持与Notification Endpoint1a的对应关系。Local NEF可能还需要向NEF发送Nnef_AFsessionWithQoS_Create request消息，Nnef_AFsessionWithQoS_Create request消息中要携带步骤S502中收到的信息，该Nnef_AFsessionWithQoS_Create request中需要携带Notification Endpoint1b。
对于QoS Notification Control事件，AF请求的业务信息中还可能包括候选业务请求(Alternative Service Requirements)，每一个Alternative Service Requirement用一个Alternative Service Requirement Id(简称AltSerId)。
S503、Local NEF或NEF向PCF发送策略授权创建消息，例如策略授权创建消息可以是Npcf_PolicyAuthorization_Create消息，Npcf_PolicyAuthorization_Create消息中包括AF Id、UE地址、请求的业务信息、事件标识(例如事件标识可以是QoS Notification Control事件的标识)，和通知端点的信息，若没有部署Local NEF，通知端点的信息可以是Notification Endpoint1a，或若部署Local NEF，通知端点的信息可以是Notification Endpoint1b。
对于QoS Notification Control事件，AF请求的业务信息中还可能包括Alternative Service Requirements，每一个Alternative Service Requirement用一个Alternative Service Requirement Id(简称AltSerId)。
Npcf_PolicyAuthorization_Create消息中还携带本地报告指示信息，用于指示需要进行本地事件报告。
S504、PCF保存接收到的策略授权创建消息之后，向Local NEF或NEF返回确认消息。
S505、Local NEF或者NEF向AF返回确认消息。
S506、PCF根据接收到的信息进行策略决策，以生成PCC规则。例如为步骤S501建立的PDU会话制定PCC规则。PCC规则中包括业务信息，该业务信息可以包括业务数据流模板和QoS参数。PCF根据AF ID、Notification Endpiont1a/Notification Endpiont1b或本地报告指示，确定在PCC规则中包括Notification Endpiont1a或Notification Endpoint1b。可选地，PCF在PCC规则中还可以携带显式的本地报告指示。在本实施例中，还可以在PCC规则携带Notification Endpiont1a/Notification Endpoint1b以及显式的本地报告指示，用于指示SMF需要本地报告事件，不限定的是，SMF仍然可以通过控制面向PCF进行事件报告。PCF可以根据多个业务数据流描述信息制定不同的PCC规则，此时PCF还在PCC规则中携带对应的业务数据流标识。
针对QoS Notification Control事件，若请求消息中携带Alternative Service Requirements，则PCF还会根据Alternative Service Requirements在PCC规则中包括Alternative QoS Parameter Sets。每个Alternative QoS Parameter Set用一个Alternative QoS Parameter Set Id(简称AltQosId)标识。同时PCC规则中包括AltQosId和AltSerId的对应关系。
S507、PCF向PDU会话对应的SMF发送PCC规则。
S508、SMF安装PCC规则后，向PCF返回确认消息。
S509、SMF执行PCC规则，根据PCC规则中携带的QoS参数执行QoS Flow绑定后，决定创建或修改QoS Flow，SMF向I-SMF发送协议数据单元会话更新请求消息，例如协议数据单元会话更新请求消息可以是Nsmf_PDU Session_Update Request消息。若创建新的QoS Flow，SMF可以为QoS Flow分配QoS flow的标识和根据PCC规则的QoS参数制定对应的QoS文档(profile)，并将QoS flow的标识和对应的QoS文档发送给I-SMF。若修改已有的QoS Flow，则SMF无需为修改后的QoS Flow分配标识但要修改已经创建的QoS文档， SMF向I-SMF发送QFI和修改后的QoS文档。SMF还可以向I-SMF发送通知端点的消息。若PCF提供了多个PCC规则，则SMF可能将不同的PCC规则绑定到不同的QoS Flow，则SMF根据绑定结果向I-SMF发送QoS Flow的标识、通知端点和业务数据流标识的对应关系。
针对QoS Notification Control事件，协议数据单元会话更新请求消息中包括QoS Notification Control指示和本地报告指示信息，用于指示需要进行本地事件报告或通过用户面进行事件报告。在本实施例中，在协议数据单元会话更新请求消息中携带本地报告指示信息，用于指示gNodeB通过用户面进行事件报告，并不排除gNodeB通过控制面进行事件报告。此外若PCC规则中携带Alternative QoS Parameter Sets，则SMF根据Alternative QoS Parameter Sets确定Alternative QoS Profiles，每个Alternative QoS Profile用Alternative QoS Profile Id(简称AltProId)标识。SMF在消息中携带AltProId和AltSerId的对应关系。
S510、I-SMF向AMF发送通信消息传输请求。
例如，该通信消息传输请求可以是Namf_Communication_N1N2MessageTransfer Request消息，Namf_Communication_N1N2MessageTransfer Request消息中携带QFI。
针对QoS Notification Control事件，Namf_Communication_N1N2MessageTransfer Request消息中包括QoS Notification Control指示和本地报告指示信息。若步骤S509的消息中携带Alternative QoS Profile，在Namf_Communication_N1N2MessageTransfer Request消息中还携带Alternative QoS Profile。
I-SMF保存QFI和通知端点的对应关系，或者I-SMF保存QFI、通知端点和业务数据里的对应关系。进一步地，I-SMF保存AltProId和AltSerId的对应关系。
S511、AMF与gNodeB交互，AMF将步骤S509接收到的信息发送给gNodeB。gNodeB进一步跟UE交互。
S512、AMF向I-SMF返回确认消息。
S513、I-SMF向SMF返回确认消息。
S514、I-SMF向Local PSA发送会话修改消息，会话修改消息中携带QFI。
针对QoS Notification Control事件，会话修改消息中携带QoS Notification Control信息用于指示Local PSA检测RAN发送的用于上报QoS Notification Control事件的数据包，并向I-SMF上报。
S515、Local PSA向I-SMF返回确认消息。
S516、针对QoS Notification Control事件,若gNodeB检测到QoS Flow的QoS Profile的QoS需求不能保障时，则gNodeB检测到事件。此时若gNodeB之前接收到了Alternative QoS Profile,则gNodeB判断当前能够保障的Alternative QoS Profile。若gNodeB正在执行的一个Alternative QoS Profile的QoS不能保障，则gNodeB检测到事件。gNodeB判断当前能够保障的其他Alternative QoS Profile。若gNodeB之前发送了QoS Flow的QoS需求不能保障的通知后，又检测到了QoS Flow的GBR能够保障，则gNodeB检测到事件。
可选的，gNodeB检测QoS Flow的QoS需求能否得到保障可以包括：gNodeB检测QoS Flow当前实际的服务质量，若QoS Flow当前实际的服务质量满足QoS Flow的QoS需求，则确 定QoS Flow的QoS需求能够得到保障，反之，则确定QoS Flow的QoS需求不能得到保障。
例如，以检测QoS Flow的保障带宽是否得到保障为例，gNodeB可以检测一段时间内QoS Flow上传输的业务数据流的最小传输速率，确定该业务数据流的最小传输速率是否满足保障传输的传输速率，若该业务数据流的最小传输速率大于或等于保障传输速率，则确定QoS Flow的QoS需求能够得到保障，反之，若该业务数据流的最小传输速率小于保障传输的传输速率，则确定QoS Flow的QoS需求不能得到保障。
S517、gNodeB向Local PSA发送数据包，数据包中携带QFI和不能保障QoS需求的指示信息或能够保障QoS需求的指示信息。针对不能保障QoS需求的指示信息，gNodeB还可能携带能够保证的Alternative QoS Profile的AltProId。gNodeB可以在一个数据包里包括多个QFI和对应的指示信息。
S518、Local PSA接收到携带QoS Notification Control事件报告的数据包，检测到事件。
S519、Local PSA向I-SMF发送事件报告。
Local PSA向I-SMF发送QFI和不能保障QoS需求的指示信息或能够保障QoS需求的指示信息。针对不能保障QoS需求的指示信息，事件报告中还包括的AltProId。I-SMF根据QFI确定Notification Endpoint1a或Notification Endpoint1b。根据AltProId确定AltSerId。若I-SMF还保存了QFI和业务数据流标识的对应关系，则I-SMF进一步确定业务数据流的标识。
S520a、若没有部署Local NEF，则I-SMF向AF发送事件报告，事件报告中携带Notification Endpoint1a。
事件报告中包括不能保障QoS需求的指示信息或能够保障QoS需求的指示信息。针对不能保障GBR的指示信息，事件报告中还包括的AltSerId。还可以在事件报告中包括业务数据流的标识。
S520b、若部署Local NEF，则I-SMF向Local NEF发送事件报告，事件报告中携带Notification Endpoint1b。
针对QoS Notification Control,事件报告中包括不能保障QoS需求的指示信息或能够保障QoS需求的指示信息。针对不能保障QoS需求的指示信息，事件报告中还包括的AltSerId。还可以在事件报告中包括业务数据流的标识。
S520c、Local NEF进一步向AF发送事件报告，事件报告中携带Notification Endpoint1a。
针对QoS Notification Control,事件报告中包括不能保障QoS需求的指示信息或能够保障QoS需求的指示信息。针对不能保障QoS需求的指示信息，事件报告中还包括的AltSerId。还可以在事件报告中包括业务数据流的标识。
对于图4b架构下的执行流程与图a架构下的流程类似，不同之处在于Local NEF向核心数据中心中的NEF发送消息，而核心数据中心中的NEF进一步向PCF发送消息。
对于图4c的架构，省略I-SMF和SMF之间的交互，由Local PSA向SMF发送通知消息，而SMF向Local NEF/AF发送通知消息。
如图6所示，当发生跨gNodeB切换时，I-SMF根据接受到的QoS flow list判断之前 发送不能保障QoS需求指示信息对应的QoS Flow是否则这个QoS flow list中，若存在QoS flow list中，则Local PSA向Local NEF或AF发送能够保障QoS需求的指示信息。具体的，主要包括如下流程：
S601、UE发生移动后，网络执行跨gNodeB的切换，例如通过Xn-based inter NG-RAN handover或Inter NG-RAN node N2 based handover完成从源gNodeB到目标(Target)gNodeB的切换。
S602、在切换过程中，目标gNodeB向AF发送QoS Flow列表，例如目标gNodeB发送路径切换请求或者切换请求确认消息，例如路径切换请求可以是N2 Path Switch Request，切换请求确认消息可以是handover request Acknowledge消息，路径切换请求或者切换请求确认消息中包括Target gNodeB接受的QoS Flow列表(List)，其中包括接受的QFI列表。QoS flow list还可能包括接受的一个或多个QoS flow的Alternative QoS Profile Id(简称AltProId)。
S603、AMF向SMF发送会话管理上下文请求消息，例如会话管理上下文请求消息可以是Nsmf_PDUSession_UpdateSMContext Request消息，Nsmf_PDUSession_UpdateSMContext Request消息中包括接受的QoS flow list。QoS flow list还可能包括接受的一个或多个QoS flow的Alternative QoS Profile Id(简称AltProId)。
S604、SMF向AMF返回确认消息。
S605a、若没有部署Local NEF，若I-SMF判断之前发送不能保障QoS需求指示信息对应的QoS Flow在这个QoS flow list中，则I-SMF根据这个QoS Flow的QFI确定Notification Endpoint1a并向AF发送事件报告，事件报告中包括能够保障QoS需求的指示信息和Notification Endpoint1b。若这个QFI有对应的AltProId，则I-SMF还在事件报告中携带对应的AltSerId。若I-SMF还保存了QFI和业务数据流标识的对应关系，则I-SMF进一步确定业务数据流的标识，在事件报告中包括业务数据流的标识。
S605b、若部署了Local NEF，若I-SMF判断之前发送不能保障QoS需求指示信息对应的QoS Flow在这个QoS flow list中，则I-SMF根据这个QoS Flow的QFI确定Notification Endpoint1b并向Local NEF发送事件报告，事件报告中包括能够保障QoS需求的指示信息和Notification Endpoint1b。若这个QFI有对应的AltProId，则I-SMF还在事件报告中携带对应的AltSerId。若I-SMF还保存了QFI和业务数据流标识的对应关系，则I-SMF进一步确定业务数据流的标识，在事件报告中包括业务数据流的标识。
S605c、若部署了Local NEF，LocalNEF根据Notification Endpoint1b确定Notification Endpoint1a并向AF发送事件报告，事件报告中包括能够保障QoS需求的指示信息和Notification Endpoint1b。针对能够保障GBR的指示信息，事件报告中还可能携带AltSerId。事件报告中还可能携带业务数据流的标识。
通过前述的举例说明可知，针对QoS Notification Control事件，gNodeB通过用户面向Local PSA报告QoS Notification Control事件，Local PSA向I-SMF报告QoS Notification Control事件。若之前下发的Alternative QoS Profile还携带AltProId，I-SMF根据AltProId确定AltSerId。I-SMF向AF或Local AF报告事件。在跨gNodeB切换过程中，I-SMF判断之前不能保障GBR的QoS Flow在这个列表中，则I-SMF向Local NEF 或AF发送能够保证GBR的事件和AltSerId。本申请实施例中，I-SMF直接向本地应用发送检测到的QoS Notification Control，减少了网络时延，还能解决切换时的事件报告问题。UPF可以向本地应用直接发送事件报告，减少路由迂回。
在本申请的前述实施例中，对于图4c的架构，AMF可以直接与SMF交互，而SMF向Local NEF/AF发送通知消息。减少了网络时延，还能解决切换时的事件报告问题。UPF可以向本地应用直接发送事件报告，减少路由迂回。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
