Description

一种报告信息的发送方法、装置及系统
本申请要求于2020年01月06日提交国家知识产权局、申请号为202010011703.X、申请名称为“一种报告信息的发送方法、装置及系统”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
本发明涉及通信技术领域，尤其是涉及一种报告信息的发送方法、设备及系统。
背景技术
在第五代(Fifth Generation，5G)通信网络中，用户设备接入网络后建立协议数据单元(protocol data unit，PDU)会话，通过PDU会话访问数据网络(data network，DN)，与部署在DN中的应用服务器，如：应用功能(application function，AF)网元进行交互。例如，PDU会话包括多条服务质量流(QoS flow)，针对不同的应用，通过不同的QoS flow传输该应用对应的业务数据流。在用户设备通过QoS Flow与AF网元交互的过程中，对于AF网元，AF网元需要感知用于传输应用的业务数据流的QoS Flow提供的服务质量能否保障应用的服务质量(quality of service，QoS)需求，以便AF网元根据QoS flow的服务质量执行相应的调整措施，使调整后的QoS Flow保障应用的QoS需求。
现有技术中，AF网元通过下述方式获取QoS Flow能否保障应用的QoS需求：AF网元向网络开放(network exposure function，NEF)网元发送订阅请求，该订阅请求包括QoS控制通知信息；NEF网元将该订阅请求发送给策略控制功能(policy control function，PCF)网元；PCF网元根据QoS控制通知信息制定相应的策略与计费控制规则(policy and charging control rule，PCC)规则，并将该PCC规则发送给会话管理功能(session management function，SMF)网元；SMF网元根据PCC规则生成PDU会话，并为该应用配置相应的QoS Flow，并将QoS Flow对应的QoS通知控制信息通过接入和移动性管理(access and mobility management function，AMF)网元发送给接入网网元。接入网网元根据QoS通知控制信息对QoS Flow进行检测，当接入网网元判断QoS Flow当前的比特率低于的保障比特率(guaranteed bit rate，GBR)时，确定QoS Flow不能保障应用的QoS需求，接入网网元通过AMF网元向SMF网元发送QoS Flow无法保障应用的QoS需求的指示信息，SMF网元进一步通过PCF网元、NEF网元将指示信息上报给AF网元。
由上可知，接入网网元生成的指示信息依次经过AMF网元、SMF网元、PCF网元、NEF网元上报给AF网元。由于接入网网元生成的指示信息经过多个核心网网元上报给AF网元，上报路径较长，会降低指示信息上报的时效性，不利于AF网元根据指示信息及时对应用的业务数据流进行调整，对于时间敏感性较高的应用，无法及时满足应用的QoS需求。
发明内容
有鉴于此，本发明的目的在于提供一种报告信息的发送方法、装置及系统，能够解决 现有技术中接入网网元上报用于指示QoS flow的QoS需求是否能够保障的指示信息的路径较长，时效性较差，不利于应用功能网元及时调整应用的业务数据流，无法满足应用的QoS需求的技术问题。

具体实施方式
本申请实施例提供的报告信息的发送方法可用于任一通信系统，该通信系统可以为第三代合作伙伴计划(3rd generation partnership project，3GPP)通信系统，例如，长期演进(long term evolution，LTE)系统，又可以为第五代(5th generation，5G)移动通信系统、新空口(new radio，NR)系统、NR V2X系统以及其他下一代通信系统，也可以为非3GPP通信系统，不予限制。下面以图1为例，对本申请实施例提供的报告信息的发送方法进行描述。
图1是本申请实施例提供的一种通信系统的示意图，如图1所示，该通信系统可以包括至少一个用户设备、接入网网元、接入和移动性管理(access and mobility management function，AMF)网元、会话管理(session management，SMF)网元、策略控制(policy control function，PCF)网元、用户面(user plane function，UPF)网元、网络开放(network exposure function，NEF)网元、应用功能(application function，AF)网元和数据网络(data network，DN)。如图1所示，应用功能网元可以部署在DN中，也可以部署在DN之外，与核心网网元的策略控制网元或者网络开放网元连接。该应用功能网元可以是第三方的应用控制平台也可以是运营商自己的设备，应用功能网元可以为多个应用服务器提供服务。
其中，图1中用户设备可以位于接入网网元的小区覆盖范围内，也可以位于接入网网 元的小区覆盖范围外。其中，用户设备可以通过上行链路(uplink，UL)与接入网网元进行空口通信，用户设备在UL上向接入网网元发送数据，接入网网元将接收到的数据转发给核心网网元，由核心网网元对该数据进行处理，并将处理后的数据通过接入网网元下发给用户设备。如：用户设备在UL上通过上行链路物理层共享信道(physical sidelink share channel，PUSCH)向接入网网元发送上行数据，接入网网元将接收到的上行数据转发给核心网网元，核心网网元对该上行数据进行处理，将处理后的上行数据通过接入网网元下发给核心网网元；其中，转发用户设备至核心网网元的上行数据的接入网网元与转发核心网网元至用户设备的下行数据的接入网网元可以是同一个接入网网元，也可以是不同的接入网网元。
用户设备也可以通过特定接口与核心网网元进行通信，如：用户设备可以通过N1接口与核心网网元中的接入和移动性管理网元进行通信。
用户设备在接入网络后可以建立协议数据单元(protocol data unit，PDU)会话，通过PDU会话访问外部数据网络DN，与部署在DN中的应用功能网元进行交互，如图1所示，根据用户访问的DN不同，网络可以根据网络策略选择接入DN的用户面网元作为PDU会话的锚点，即协议数据单元锚点(PDU session anchor，PSA)，通过PSA的N6接口访问应用功能网元，同一个应用的应用功能网元可以部署在多个位置，网络可以根据用户设备的接入位置，选择靠近用户设备同时又能支持用户设备访问DN的PSA，以减少路由迂回，降低网络延迟，通常，应用功能网元部署在移动边缘计算(mobile edge compute，MEC)环境中，对于应用，需要感知到业务数据流传输路径的QoS信息，以便在应用层执行相应的调整。
其中，图1中的用户设备(user equipment，UE)可以称为终端(terminal)或者移动台(mobile station，MS)或者移动终端(mobile terminal，MT)等。具体的，图1中的用户设备可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。用户设备还可以是虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、车载终端、具有车对车(vehicle-to-vehicle，V2V)通信能力的车辆、智能网联车、有无人机对无人机(UAV to UAV，U2U)通信能力的无人机等等，不予限制。

图1中的接入和移动性管理网元，主要负责用户设备的接入认证、移动性管理、各个功能网元间的信令交互等工作，如：对用户的注册状态、用户的连接状态、用户注册入网、跟踪区更新、小区切换用户认证和密钥安全等进行管理。
图1中的会话管理网元，可以称为会话管理功能或者多播/组播业务管理功能 (multicast/broadcast-service management function，MB-SMF)或者多播会话管理网元等，不予限制。会话管理网元主要用于实现用户面传输逻辑通道，如：分组数据单元(packet data unit，PDU)会话的建立、释放和更改等会话管理功能。在一些场景下，SMF可能无法直接管理一些区域的UPF，如图1所示，可以插入中间会话管理(intermediate SMF，I-SMF)网元，来对这些UPF进行管理。
图1中的策略控制网元，用于根据应用的业务数据流的QoS需求，确定应用的业务数据流对应的QoS参数集，根据QoS参数集制定策略与计费控制规则(policy and charging control rule，PCC规则)，并将PCC规则发送给会话管理网元。
图1中的用户面网元，可以称为PDU会话锚点(PSF)、用户面功能或者多播/组播用户面功能(multicast/broadcast user plane fuction，MB-UPF)。用户面网元可以作为用户面传输逻辑通道上的锚点，主要用于完成用户面数据的路由转发等功能，如：与终端之间建立通道(即用户面传输逻辑通道)，在该通道上转发终端和DN之间的数据包以及负责对终端的数据报文过滤、数据转发、速率控制、生成计费信息等。多播/组播(multicast/broadcast，MB)业务控制器(MB service controller)，具有群组管理、安全管理以及业务公告等业务管理功能。
图1中的应用功能网元，主要是提供应用服务器和核心网中的网元交互的中间功能实体，应用服务器可以通过它实现对网络服务质量和计费的动态控制、保障SLA需求、获取核心网中某个网元的运行信息等。在本申请实施例中，应用功能网元可以为运营商部署的功能实体，也可以为服务提供商部署的功能实体，该服务提供商可以为第三方服务提供商，还可以为运营商内部的服务提供商，不予限制；当应用功能网元为运营商部署的功能实体时，应用功能网元可以直接与核心网中的网元交互，当应用功能网元为第三方服务提供商部署的功能实体时，应用功能网元可以通过图1中的网络开放网元与核心网中的网元交互。
需要说明的是，本申请实施例的多个终端、接入网网元以及核心网网元都可以为一个或多个芯片，也可以为片上系统(system on chip，SOC)等。图1仅为示例性附图，其包括的设备数量不受限制。此外，除图1所示设备之外，该通信系统还可以包括其他设备。图1中各个设备的名称、各个链路的命名不受限制，除图1所示名称之外，各个设备、各个链路还可以命名为其他名称。除图1所示网元外，图1所示网络还可以包括网络切片选择(Network Slice Selection Function，NSSF)网元、网络仓库(Network Repository Function，NRF)网元、认证服务(authentication server function，AUSF)网元、统一数据存储库(unified data repository，UDR)网元、网络数据分析(network data analytics function，NWDAF)网元等，不予限制。
目前，现有技术中，如图1所示，接入网网元生成的QoS Flow的QoS需求能否得到保障的指示信息依次经过中央数据中心的接入和移动性管理网元、会话管理网元、策略控制网元、网络开放网元上报给本地数据中心的应用功能网元，由于接入网网元生成的指示信息需要经过多个核心网网元上报给应用功能网元，上报路径较长，会降低指示信息上报的时效性，不利于应用功能网元根据指示信息及时对应用的业务数据流进行调整，对于时间敏感性较高的应用，无法及时满足应用的QoS需求。
为解决该问题，如图1所示，本申请实施例提供一种报告信息的发送方法，通过将接入网网元生成的指示信息通过本地数据中心的用户面网元向应用功能网元进行上报，与现 有技术相比，可以缩短上报路径，提高指示信息上报的时效性，便于应用功能网元根据指示信息及时对应用的业务数据流进行调整，对于时间敏感性较高的应用，可以及时满足应用的QoS需求。具体的，该实现方法可以参照下述图3-图10所示方法对应的实施例。
具体实现时，图1所示，如：各个终端、接入网网元和核心网网元均可以采用图2所示的组成结构，或者包括图2所示的部件。图2为本申请实施例提供的一种通信装置200的组成示意图，该通信装置200可以为终端或者终端中的芯片或者片上系统；也可以为接入网网元或者接入网网元中的芯片或者片上系统；也可以为核心网网元或者核心网网元中的芯片或者片上系统。如图2所示，该通信装置200包括处理器201，收发器202以及通信线路203。

通信线路203，用于在通信装置200所包括的各部件之间传送信息。
存储器204，用于存储指令。其中，指令可以是计算机程序。
其中，存储器204可以是只读存储器(read-only memory，ROM)或可存储静态信息和/或指令的其他类型的静态存储设备，也可以是随机存取存储器(random access memory，RAM)或可存储信息和/或指令的其他类型的动态存储设备，还可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或其他磁存储设备等，不予限制。
需要指出的是，存储器204可以独立于处理器201存在，也可以和处理器201集成在一起。存储器204可以用于存储指令或者程序代码或者一些数据等。存储器204可以位于通信装置200内，也可以位于通信装置200外，不予限制。处理器201，用于执行存储器204中存储的指令，以实现本申请下述实施例提供的报告信息的发送方法。

此外，本申请的各实施例之间涉及的动作、术语等均可以相互参考，不予限制。本申请的实施例中各个设备之间交互的消息名称或消息中的参数名称等只是一个示例，具体实现中也可以采用其他的名称，不予限制。
下面结合图1所示通信系统，以第一接入网网元将用于指示第一QoS Flow的QoS需求能否得到保障的第一指示信息上报给用户面网元，用户面网元对第一指示信息进行处理得到第一报告信息并上报给应用功能网元为例，对本申请实施例提供的报告信息的发送方法进行描述，其中，第一接入网网元可以为通信系统中的任一接入网网元，第一QoS Flow可以为网络中任一QoS Flow，下述实施例所述的接入网网元、用户面网元、应用功能网元可以具备图2所示部件。
图3为本申请实施例提供的一种报告信息的发送方法的流程图，在执行图3之前，会话管理网元已采用现有技术为应用对应的业务数据流确定对应的QoS Flow。如图3所示，该方法可以包括：
步骤301、第一接入网网元检测第一QoS Flow的QoS需求能否得到保障。
其中，第一QoS Flow可以用于传输某个应用对应的业务数据流或者可以描述为第一QoS Flow可以用于从第一接入网设备向用户设备传输某个应用对应的业务数据流。策略控制网元根据该应用的业务数据流的QoS需求确定对应的PCC规则的QoS参数。会话管理网元进一步根据QoS参数确定第一QoS Flow的QoS参数(即第一QoS Flow的QoS需求)，最终第一QoS Flow的QoS需求满足与该应用对应的业务数据流的QoS需求，即通过第一QoS Flow传输该应用对应的业务数据流可以满足业务数据流的QoS需求。
其中，第一QoS Flow的QoS需求可以包括最大带宽(即最大传输比特率，max bitrate)、保障带宽(即保障比特率,guaranteed bitrate)、包延迟预计(packet delay budget)和包错误率(packet error rate)中的一种或多种等等；业务数据流的QoS需求可以包括媒体类型、最大请求带宽、最小请求带宽、最大支持带宽、最小期望带宽、最大丢包率和QoS参考标识中的一种或多种。
示例性的，第一接入网网元检测第一QoS Flow的QoS需求能否得到保障可以包括：第一接入网网元检测第一QoS Flow当前实际的服务质量，若第一QoS Flow当前实际的服务质量满足第一QoS Flow的QoS需求，则确定第一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，以检测第一QoS Flow的保障带宽是否得到保障为例，第一接入网设备可以检测一段时间内第一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等于保障传输速率，则确定第一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。
步骤302、第一接入网网元向用户面网元发送第一消息。
其中，第一消息可以包括第一QoS Flow的标识和第一指示信息；或者，第一消息可以包括第一指示信息。示例性的，第一接入网设备可以根据第六指示信息，第一QoS Flow的标识和第一指示信息封装在第一消息中。
其中，第六指示信息可以用于指示将第一QoS Flow的标识和第一指示信息通过同一消息发送给用户面网元，第六指示信息可以由会话管理网元发送给第一接入网网元。
其中，第一QoS Flow的标识可以用于标识第一QoS Flow，第一QoS Flow的标识可以为QFI或者5QI等，不予限制。第一QoS Flow的标识可以由会话管理网元在确定第一QoS Flow时发送给第一接入网设备。
其中，当第一消息包括第一QoS Flow的标识和第一指示信息时，第一QoS Flow的标识和第一指示信息对应，第一指示信息可以用于指示第一QoS Flow的QoS需求能否得到保障或者用于指示某个QoS Flow的QoS需求能否得到保障。例如，若第一接入网网元检测第一QoS Flow的QoS需求不能得到保障，则第一指示信息用于指示第一QoS Flow的QoS需求不能得到保障；若第一接入网网元检测第一QoS Flow的QoS需求能够得到保障(通常是再次检测，确定能够得到保障)，则第一指示信息用于指示第一QoS Flow的QoS需求能够得到保障。
当第一消息包括第一指示信息时，第一指示信息可以用于显式指示第一QoS Flow的QoS需求能否得到保障，如：当第一消息包括第一指示信息时，第一指示信息可以包括第一QoS Flow的标识；或者，当第一消息包括第一指示信息时，第一指示信息用于指示某个QoS Flow的QoS需求能否得到保障，此时，第一指示信息与第一QoS Flow对应或者具有绑定关系，如：可以预配置QoS Flow与消息类型的对应关系，第一指示信息的消息类型与第一QoS Flow对应的消息类型相同，通过第一指示信息的消息类型以及QoS Flow与消息类型的对应关系可以确定第一指示信息用于指示第一QoS Flow的QoS需求能否得到保障。
示例性的，第一接入网网元向用户面网元发送第一消息可以包括：第一接入网设备根据用于指示通过优化路径发送QoS需求能否得到保障的通知的指示信息，向用户面网元发送第一消息。
其中，优化路径可以指向应用功能网元上报QoS需求能否得到保障的最短/最优路径，本申请实施例中，优化路径可以包括从接入网网元→本地数据中心的用户面网元→应用功能网元的路径。从第一接入网网元角度看，优化路径可以认为是通过用户面上报QoS需求能否得到保障。
具体的，优化路径的相关描述以及用于指示通过优化路径发送QoS需求能否得到保障的通知的指示信息的配置方式可参照图4对应的实施例中所述。
步骤303、用户面网元接收第一消息，根据第一消息向应用功能网元发送第一报告信息。
其中，第一报告信息中可以包括第二指示信息。第二指示信息可以用于指示应用的业务数据流的QoS需求能否得到保障。若第一指示信息用于指示第一QoS Flow的QoS需求不能得到保障，则确定第二指示信息用于指示第一QoS Flow对应的应用的业务数据流的QoS需求不能得到保障；或者，若第一指示信息用于指示第一QoS Flow的QoS需求能够得到保障，第二指示信息用于指示第一QoS Flow对应的应用的业务 数据流的QoS需求能够得到保障。
可选的，除包括第二指示信息之外，第一报告信息还包括业务数据流的标识，业务数据流的标识可以用于标识业务数据流。
具体的，当第一消息包括第一QoS Flow的标识和第一指示信息，且第一QoS Flow的标识和第一指示信息对应时，用户面网元接收到第一消息后，可以根据第一消息中的第一QoS Flow的标识、以及QoS Flow的标识与应用的业务数据流的标识间的对应关系，确定与第一QoS Flow对应的应用的业务数据流，并根据第一指示信息生成用于指示该应用的业务数据流的QoS需求能否得到保障的第二指示信息，将第二指示信息携带在第一报告信息中上报给应用功能网元。
当第一消息包括第一指示信息，第一指示信息包括第一QoS Flow的标识时，用户面网元可以根据第一指示信息包括的第一QoS Flow的标识、以及QoS Flow的标识与应用的业务数据流的标识间的对应关系，确定与第一QoS Flow对应的应用的业务数据流，并根据第一指示信息生成用于指示该应用的业务数据流的QoS需求能否得到保障的第二指示信息，将第二指示信息携带在第一报告信息中上报给应用功能网元。
当第一消息包括第一指示信息，且第一指示信息与第一QoS Flow对应时，用户面网元可以根据第一指示信息确定第一QoS Flow，如：通过第一指示信息的消息类型以及QoS Flow与消息类型的对应关系确定第一QoS Flow，根据第一QoS Flow的标识、以及QoS Flow的标识与应用的业务数据流的标识间的对应关系，确定与第一QoS Flow对应的应用的业务数据流，并根据第一指示信息生成用于指示该应用的业务数据流的QoS需求能否得到保障的第二指示信息，将第二指示信息携带在第一报告信息中上报给应用功能网元。
其中，QoS Flow的标识与应用的业务数据流的标识间的对应关系可以由会话管理网元在采用现有技术确定应用的业务数据流对应的QoS Flow后发送给用户面网元。
一种示例中，用户面网元向应用功能网元发送第一报告信息可以包括：用户面网元根据用于指示通过优化路径发送QoS需求能否得到保障的通知的指示信息，向应用功能网元发送第一报告信息。
其中，用于指示通过优化路径发送QoS需求能否得到保障的通知的指示信息可以由会话管理网元发送给用户面网元。具体的，该过程可参照图4对应的实施例中所述。
又一种示例中，用户面网元向应用功能网元发送第一报告信息可以包括：户面网元根据用于指示用户面网元向应用功能网元发送第一报告信息的第五指示信息，向应用功能网元发送第一报告信息。
其中，第五指示信息可以由会话管理网元发送给用户面网元。具体的，该过程可参照图4对应的实施例中所述。
具体的，用户面网元向应用功能网元发送第一报告信息可以包括：

具体的，第四策略的相关描述以及实现过程可参照图4对应的实施例中所述。
进一步的，应用功能网元接收到第一报告信息后，可以根据第一报告信息对应用的业务数据流进行调整，满足应用的QoS需求。
需要说明的是，图3以一个QoS Flow的QoS需求是否得到保障为例进行了说明，类似的，可以参照图3所示，检测两个或者两个以上的QoS Flow的QoS需求是否得到保障，并根据每个QoS Flow的QoS需求是否得到保障向应用功能网元发送每个QoS Flow对应的业务数据流的QoS需求是否得到保障。其中，一个应用可以包括多个业务数据流，不同的业务数据流对应不同的QoS Flow，不同的QoS Flow可以对应不同的接入网网元。

另一种可能的设计中，当用户面网元接收到会话管理网元发送的第四策略时，用户面网元向会话管理网元发送第一报告信息，会话管理网元确定本地网络开放网元或应用功能网元的通知端点，进一步发送第一报告信息。
可选的，当会话管理网元向用户面网元发送第五指示信息时，用户面网元根据会话管理网元发送的第五指示信息，将第一报告信息发送给应用功能网元；或者，当会话管理网元向用户面网元发送第八指示信息时，用户面网元根据会话管理网元发送的第八指示信息，将第一报告信息发送给应用功能网元。
其中，第五指示信息、第八指示信息的相关描述可参照上述，不予赘述。

进一步可选的，第一接入网网元还通过接入和移动性管理网元向会话管理网元发送第一消息，以使会话管理网元根据第一消息确定第一QoS Flow的QoS需求能否得到保障，根据第一QoS Flow的QoS需求情况调整/修改第一QoS Flow，使得调整后的第一QoS Flow满足应用的业务数据流的传输需求。
进一步的，由于用户设备具有移动性，用户设备可能会从第一接入网网元的覆盖区域移动到第二接入网网元的覆盖区域。当用户设备从第一接入网网元的覆盖区域移动到第二接入网网元的覆盖区域时，用于传输应用的业务数据流的QoS Flow发生切换，用于传输应用的业务数据流的QoS Flow的QoS需求能否得到保障可能会发生变化，进而导致应用的业务数据流的QoS需求是否能够保障会发生变化，如：原本用于传输应用的业务数据流的QoS Flow为QoS Flow1，QoS Flow1的QoS需求能够保障，应用的业务数据流的QoS需求能够保障，而用户设备移动到新的接入网网元的覆盖区域时，用于传输应用的业务数据流的QoS Flow切换为QoS Flow2，QoS Flow2的QoS需求不 能够保障，应用的业务数据流的QoS需求不能够保障。此时，在QoS Flow的QoS需求的保障情况发生变化，应用的业务数据流的QoS需求发生变化的情况下，若不及时将应用的业务数据流的QoS需求情况通知应用功能网元，则会导致应用功能网元对应用的业务数据流的QoS需求情况理解错误，影响应用的业务数据流的传输。
为解决上述问题，本申请实施例中，可以在用户设备从第一接入网设备的覆盖区域移动到第二接入网设备的覆盖区域时，由第二接入网设备结合第一接入网设备检测到QoS Flow的QoS需求情况以及第一接入网设备检测到QoS Flow的QoS需求情况，向应用功能网元上报应用的业务数据流的QoS需求情况。具体的，第二接入网设备可以采用下述图5-图9所示方法中任一方法，通过用户面网元向应用功能网元发送应用的业务数据流的QoS需求是否能够保障的第二报告信息。
