一种信息处理方法及装置
相关申请的交叉引用
本申请要求在2019年11月30日提交中国专利局、申请号为201911209035.5、申请名称为“一种信息处理方法及装置”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，尤其涉及一种信息处理方法及装置。
背景技术
网络切片(network slice)是在运营商的通信网络中划分出来的一个具备特定网络特性的逻辑网络，是满足第三代合作伙伴项目(3rd generation partnership project，3GPP)提出的第五代(5th generation，5G)移动通信技术关于网络差异化需求的关键技术。一张物理网络可以被抽象划分成多个网络切片，每个网络切片构成一个端到端的逻辑网络，彼此之间逻辑上是隔离的。每个网络切片可以按照需求方的要求灵活地提供一种或多种网络服务，并且和网络中的其它网络切片互不影响。
通常情况下，不同网络切片的网络性能要求并不相同，如增强实现(augmented reality，AR)或虚拟实现(virtual reality，VR)业务的网络切片要求大带宽、低时延业务；物联网(internet of things，IOT)业务的网络切片要求支持海量终端接入，但带宽小且对时延没要求。运营商将通信网络划分成一系列的网络切片后，各个网络切片彼此之间是逻辑隔离，同时又具备不同的网络特征，一个客户可以在运营商订购多个网络切片，从而使得运营商的一张物理网络就能满足不同应用对网络的差异化需求。
运营商可以根据客户订单为客户创建网络切片，在为客户创建网络切片时，运营商和客户通常会根据业务需求签署网络切片的服务等级协议(service level agreement，SLA)。运营商在网络切片的运行过程中需要确保网络切片提供的服务和性能能够达到所签署的SLA的要求。然而，如何确定服务等级，以确保在网络切片运行时保障服务等级，目前尚未较好的解决方案。
发明内容
本申请实施例提供一种信息处理方法及装置，用于确定网络切片的服务等级，以确保在网络切片运行时保障服务等级。
第一方面，提供一种信息处理方法，该方法的执行主体可以是第一网元，例如为网络数据分析功能(network data analytics function，NWDAF)或者管理数据分析系统(management data analytics system，MDAS)，也可以是应用于第一网元中的芯片。下面以执行主体是第一网元为例进行描述。该方法包括：
针对提供的至少一个网络性能场景中的每一个网络性能场景，第一网元获取一组网络数据，每一组网络数据至少包括来自终端设备的第一信息或来自应用服务器的第二信息， 所述第一信息用于指示所述终端设备的业务体验质量和/或网络性能指标，所述第二信息至少用于指示所述应用服务器的业务体验质量；其中，所述网络性能场景为终端设备进行业务的网络环境，每个网络性能场景对应至少一种网络性能指标；
第一网元根据获得的多组网络数据确定服务等级模型，所述服务等级模型指示至少一个组合与业务体验质量的等级的对应关系，所述服务等级模型用于确定当前的网络切片的服务等级，其中，每个组合对应至少一种网络性能指标。
在本申请实施例中，提供了用于测试业务体验质量的多个网络性能场景，从而可以基于这多个网络性能场景测试多种业务，相较于目前典型的几种业务来说，适用范围更广。同时，由于网络性能场景也就是模拟终端设备进行业务的网络环境，可以模拟各种各样的网络环境，基于此得出的业务测试结果，例如终端设备的业务体验质量和/或网络连接的网络性能指标更为合理，根据业务测试结果得到的服务等级模型确定的网络切片的服务等级也更为合理。采用该方案，根据网络的实际运行情况，基于上述的服务等级模型可以确定较为合理的服务等级，既能够保证较好的应用体验，又可以避免出现过量的性能保证，尽量节约无线覆盖成本和资源。
在一种可能的设计中，所述方法还包括：
所述第一网元将所述服务等级模型发送给第二网元。
在本申请实施例中，第一网元获得的服务等级模型可以存储于网络中的其它网元，这样其它网元可以基于该服务等级模型确定当前的网络切片的服务等级，使用范围更广。
在本申请实施例中，第一网元可以基于服务等级模型确定当前的网络切片的服务等级，进而根据确定的服务等级对网络切片进行后续处理，至少包括如下的处理：
示例性的，所述第一网元在确定所述服务等级不满足预设条件时，对所述当前的网络切片或者使用所述当前网络切片的终端设备的资源进行管理，其中，所述预设条件至少包括可接受等级。采用该方案，可以根据网络运行的实际情况，管理当前的网络切片或者使用当前网络切片的终端设备的资源，以改变当前网络切片的网络性能，尽量保障合理的服务等级。
示例性的，所述第一网元根据所述服务等级对使用所述当前的网络切片的终端设备进行计费。采用该方案，可以支持变化的服务等级的计费，相较于目前不支持按照变化的服务等级进行计费，更为合理。
在一种可能的设计中，所述第一网元基于所述服务等级模型确定当前的网络切片的服务等级，包括：
所述第一网元获取至少一个所述第一信息，并基于所述至少一个所述第一信息中的终端设备的网络性能指标和所述服务等级模型确定所述网络切片的服务等级；和/或，
所述第一网元获取网络中的功能网元的网络性能指标数据，并基于所述功能网元的网络性能指标和所述服务等级模型确定所述网络切片的服务等级。
在本申请实施例中，第一网元可以根据使用当前的网络切片的终端设备的网络性能指标数据，和/或网络中的功能网元的网络性能指标数据确定服务等级，也就是根据网络实际运行情况，较为及时地确定服务等级，从而可以及时地调整网络切片，尽量保证网络切片的服务等级。
在一种可能的设计中，所述第一网元获取至少一个所述第一信息，并基于所述至少一个所述第一信息中的终端设备的网络性能指标和所述服务等级模型确定所述网络切片的 服务等级，包括：
若使用所述当前的网络切片的终端设备为多个终端设备，则所述第一网元根据各个终端设备的网络性能指标和所述服务等级模型确定所述网络切片的第一服务等级；
所述第一网元根据与各个业务体验质量的等级分别对应的终端设备的数量，或根据与各个业务体验质量的等级分别对应的终端设备在所述多个终端设备中的占比，对所述第一服务等级进行修正，获得所述当前的网络切片的第二服务等级。
考虑到一个终端设备可能接入多个网络切片，多个终端设备也可能接入一个网络切片，在本申请实施例中，基于多个终端设备的网络性能指标数据和服务等级模型确定出对应的第一服务等级后，可以进一步根据各个业务体验质量的等级对应的终端设备的数量对第一服务等级进行修改，或者根据或者各个业务体验质量的等级对应的终端设备在多个终端设备中的占比对第一服务等级进行修改，以得到更为准确的第二服务等级。
在一种可能的设计中，第一网元获取一组网络数据，包括：
所述第一网元从区块链系统中的至少一条数据链获取所述一组网络数据，其中，所述至少一条数据链至少用于存储来自所述终端设备的第一信息或来自所述应用服务器的第二信息。
在本申请实施例中，提供了前述各个实施例的另一种实现手段，例如通过区块链技术实现前述各个实施例。一方面可以保证系统中数据交互的安全性，另一方面系统中各个网元可以从区块链中的数据链直接获取需要的数据，提高网元获取数据的便利性。

在本申请实施例中，基于区块链的应用场景，支持按照服务等级的计费功能。由于本申请实施例可以当前确定的服务等级进行计费，也就是可以按照变化的服务等级进行计费，相较于目前不支持按照变化的服务等级进行计费，更为合理。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
运营商基于客户的请求为客户创建或部署网络切片，具体的，订购网络切片的客户通过通信业务管理功能(communication service management function，CSMF)向运营商的网络切片管理功能(network slice management function，NSMF)发送创建网络切片的请求消息，该请求消息可以携带切片类型和业务需求，其中业务需求包括业务特征、网络切片覆盖范围，以及同时接入网络切片的最大用户数量等信息。NSMF收到该请求消息，根据该请求消息完成网络切片的创建和部署。
为了实现网络切片的创建和部署，目前3GPP标准中给出的一些典型应用场景下的业务特征和性能需求，例如包括业务的性能需求(各种关键性能指标需求)、终端设备的移动速度、单位面积内终端设备的数量(即终端密度)和需要提供服务的范围中的至少一种性能需求，或者其他可能的性能需求等等。
示例性的，表1示出了高数据速率和高流量密度的业务特征和性能需求，表2示出了低时延高可靠的业务特征和性能需求。运营商根据表1和/或表2可以将客户的行业应用需求转换成网络切片需要支持的性能需求，也可以理解为网络切片需要满足的关键性能指标(key performance indicator，KPI)，然后根据这些KPI确定所需的网络资源，为用户分配网络资源创建网络切片。
表1-高数据速率和高流量密度的业务特征和性能需求
Figure PCTCN2020107931-appb-000001
Figure PCTCN2020107931-appb-000002
表2低时延高可靠的业务特征和性能需求
Figure PCTCN2020107931-appb-000003
在生成网络切片订单的阶段，运营商和客户根据表1或表2确定网络切片需要满足的KPI需求作为服务等级，并签署网络切片的SLA。在网络切片的运行阶段，NSMF可以监 控CPU、内存和存储等网络资源的使用率，如果网络资源的使用率超过门限就触发资源扩容，为网络切片分配更多的网络资源，确保网络切片提供的通信服务能够满足签署的SLA。
表1和表2只是列举了一部分典型应用的场景，但是，行业应用的业务种类繁多，如果按照表1和表2的业务特征和性能需求来为客户创建网络切片，那么所创建的网络切片提供的网络服务不一定能够保证较好的应用体验。例如，针对某个业务，运营商按照表1和表2的业务特征和性能需求为客户创建的网络切片可能无法保证较好的业务体验质量。又例如，针对某个业务，运营商按照表1和表2的业务特征和性能需求为客户创建的网络切片可能出现过量的性能保证，这就导致较高的无线覆盖成本和资源浪费。出现过量的性能保证，这就导致较高的无线覆盖成本和资源浪费。
另外，一些行业应用并不需要SLA刚性保障，在一种可能的应用场景，某些应用只需要对SLA进行弹性保障即可，即在一定范围内的SLA保证服务质量即可。而目前按照表1和表2的业务特征和性能需求为客户创建的网络切片满足的SLA是固定的，即目前不支持调整SLA，灵活性较差。
鉴于此，本申请实施例提供了一种信息处理方法及装置，可以根据业务实际的性能来确定合理的SLA，并根据确定的SLA调整网络切片，以尽量保证较好的业务体验质量的同时，避免过量的性能保证。
本申请实施例提供的信息处理方法可以适用于如图1所示的系统。请参见图1，示出了本申请实施例适用的一种系统架构示意图，该系统架构包括应用客户端、网络性能模拟器、应用服务器以及连接应用服务器、应用客户端和网络性能模拟器的网络数据分析网元。应用客户端也可以理解为是终端设备。
其中，终端设备：是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。终端设备有时也可以称为用户设备(user equipment，UE)、移动台和远方站等，本申请的实施例对终端设备所采用的具体技术、设备形态以及名称不做限定。
应用服务器：可以向运营商的通信网络的控制面网元提供各类应用的服务数据，或者从通信网络的控制面网元获得网络的数据信息和控制信息。在一些实施例中，应用服务器也可以称为应用功能网元，例如在5G通信系统中，应用服务器可以是应用功能(application function，AF)。
网络性能模拟器，网络性能模拟器可以提供多个网络性能场景。一个网络性能场景对应至少一种网络性能指标，网络性能指标参数可以包括带宽、时延、丢包率、误码率、可靠性等参数。不同的网络性能场景的部分或全部网络性能指标参数可能不同。应用客户端可以使用网络性能模拟器提供的网络性能场景下的网络连接，实现进行业务。应理解，应用客户端的网络连接的性能指标与设定的网络性能场景的网络性能指标匹配。
应用客户端在某个网络性能场景下的网络连接，除了进行业务，还可以对进行的业务 进行测试。也就是测试在该网络性能场景提供的网络连接下，该业务的体验质量、网络连接的性能指标等。为了便于描述，下文中将业务的体验质量称为业务体验质量。
在本申请实施例中，可以为业务体验质量划分等级，示例性的，例如包括“不可接受等级”和“可接受等级”，其中，“不可接受等级”表示用户体验较差；可接受等级”表示用户体验较好。在一些实施例中，“可接受等级”又可以按照用户体验的好坏依次划分为“优”、“良”、“中”等多个等级。应理解，在一些实施例中，业务体验质量的等级可以包括“不可接受等级”、“可接受等级”、“优”、“良”和“中”等。需要说明的是，上述业务体验质量的等级划分仅是举例，本申请实施例对业务体验质量的等级的数量不作限制。应用客户端在不同的网络性能场景的网络连接进行业务，业务体验质量的等级可能也所有不同，从这个角度而言，网络性能模拟器也可以认为能够模拟各种服务等级的网络性能场景。
应理解，网络性能模拟器可以是软件功能，可以部署在用户内部网络中，从而应用客户端和应用服务器都可以在用户内部网络中部署网络性能模拟器。网络性能模拟器也可以是运营商提供的公有云中的组件，从而应用服务器可以部署在公有云，应用客户端可以通过接入公有云访问应用服务器，并使用网络性能模拟器。应用客户端可以使用网络性能模拟器模拟的网络性能场景，其中应用客户端到应用服务器，或者应用客户端之间通过网络性能模拟器实现网络连接，网络连接的带宽、时延、丢包率、误码率和可靠性等性能指标遵照网络性能模拟器模拟的网络性能场景。图1以网络模拟器部署在运营商提供的公有云中的组件，也就是独立于应用客户端和应用服务器为例。
网络数据分析网元：可以从应用客户端、网络性能模拟器和应用服务器收集数据，并进行分析和预测。例如网络数据分析网元可以是网络数据分析功能(network data analytics function，NWDAF)或者管理数据分析系统(management data analytics system，MDAS)或其它具有大数据分析功能或人工智能处理功能的单元等。其中，NWDAF可以从各个网络功能(network function，NF)、AF以及运行管理和维护(operation,administration,and maintenance，OAM)系统，例如策略控制网元、会话管理网元、用户面网元、接入管理网元、应用功能网元(通过网络能力开放功能(network exposure function，NEF)网元)收集数据，并进行分析和预测。MDAS可以在网络管理系统中负责收集性能统计和告警等网络管理数据并进行分析，输出分析结果或推荐的性能指标。应理解网络数据分析网元可以是软件功能模块，部署在某个实体设备，也可以是实体设备。图1以网络数据分析网元是独立于应用客户端和应用服务器的实体设备为例。当然，应理解，网络性能模拟器作为软件功能，也可以部署在网络数据分析网元。
其中，网络数据可以认为是应用客户端在网络性能场景下的网络环境中进行某个业务，对该业务进行测试的数据，例如可以包括用于表征业务体验质量的数据(也称为业务体验质量数据或者业务体验质量)和/或用于表征网络连接到网络性能指标的数据(也称为网络性能指标数据或者网络性能指标)。由于某个应用客户端在网络性能场景下的网络环境中进行某个业务，可能涉及到该应用客户端和应用服务器的交互，或者也可能涉及到该应用客户端与其他功能网元的交互。所以业务体验质量数据可以来自应用客户端，也可以来自应用服务器；网络性能指标数据可以来自应用客户端，也可以来自网络中的功能网元，例如网络性能模拟器。为了便于描述，在下文中，将来自应用客户端的网络数据称为第一信息，那么第一信息至少包括来自应用客户端的业务体验质量数据和/或网络性能指标数据。同理，将来自应用服务器的网络数据称为第二信息，那么第二信息至少包括应用服务器的 业务体验质量数据。应理解，如果网络性能模拟器部署在应用服务器，那么第二信息还可以包括网络性能模拟器的网络性能指标数据。如果网络性能模拟器独立于应用客户端和应用服务器，可以将来自网络性能模拟器的网络数据称为第三信息，那么第三信息至少包括来自网络性能模拟器的网络性能指标数据。
网络数据分析网元可以根据第一信息和第二信息评估应用客户端在某个网络性能场景下进行业务的业务体验质量的等级(也称为业务体验质量等级)。如果存在多个网络性能场景和多个业务，那么网络数据分析网元针对每个网络性能场景的多个业务，分别评估业务体验质量等级，也就是网络性能场景能够提供的业务服务等级。从这个角度来说，网络数据分析网元可以确定适合不同业务的服务等级。
需要说明的是：(1)本申请实施例中所述的网元或者模拟器可以是硬件，或者也可以是从功能上划分的软件或者以上二者结合后的结构。本申请实施例中所述的网元也可以称为功能实体，比如网络数据分析网元也可以称为网络数据分析功能实体。各个网元的名称在本申请实施例中不做限定，本领域技术人员可以将上述网元的名称更换为其它名称而执行相同的功能。
(2)上述所示意的系统架构可以适用于各种无线接入技术的通信系统中，例如，长期演进(long term evolution，LTE)通信系统、第五代(5th generation，5G)通信系统以及其它可能的通信系统中。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
(3)本申请实施例中涉及的第一、第二等各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围，也不表示先后顺序。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。“至少一个”是指一个或者多个。至少两个是指两个或者多个。“至少一个”、“任意一个”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个、种)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
图1所示的系统架构是本申请实施例能够适用的一种示例性的架构，本申请实施例提供的方法还可以应用于其他系统架构中。本领域技术人员可以将图1所示的系统架构中的各个逻辑功能节点的名称更换为其它名称，当执行相同的功能时，属于本申请保护的范围。
基于图1所示意的系统架构，请参见图2，本申请实施例提供的信息处理方法的流程描述如下所述。
S201、针对提供的至少一个网络性能场景中的每一个网络性能场景，第一网元获取一组网络数据，获得多组网络数据。
在一种应用场景中，网络性能模拟器提供至少一个网络性能场景。终端设备可以在至少一个网络性能场景中的每一个网络性能场景的网络连接进行业务。以针对某个网络性能场景为例，终端设备可以基于该网络性能场景进行业务测试，也就是终端设备进行业务体验测试或者网络性能测试。终端设备可以将测试结果，也就是业务体验质量数据和网络性能指标数据发送给第一网元，例如为NWDAF。应理解，业务体验质量数据包括用于指示 业务体验质量等级的数据。网络性能指标数据包括网络连接的带宽、时延、丢包率和误码率等。同理，进行该业务所涉及的其他执行主体，也可以进行业务测试，将测试结果发送给第一网元。例如应用服务器将业务体验质量数据发送给第一网元。网络性能模拟器将网络性能指标数据，例如网络连接的带宽、时延、丢包率、误码率和可靠性等发送给第一网元。由于测试结果包括来自多个执行主体的网络数据，所以针对每个网络性能场景，第一网元获取的网络数据可以称为一组网络数据。应理解，针对多个网络性能场景，第一网元获取的是多组网络数据。
示例性的，请参见图3，为一个网络性能场景下，第一网元收集网络数据的示意图，包括以下步骤：
S301、网络性能模拟器提供第一网络性能场景。
S302、终端设备在第一网络性能场景下的网络连接，进行业务测试。
第一网络性能场景设定至少一种网络性能指标参数，终端设备到应用服务器，或者两个终端设备之间，使用第一网络性能场景下的网络连接进行业务。终端设备进行业务时，可以对进行的业务进行测试，获得测试结果，例如进行该业务的业务体验质量数据，该网络连接的网络性能指标数据等。应理解，终端设备在第一网络性能场景下的网络连接进行业务，可以通过网络性能模拟器与应用服务器进行交互，所以图3中S302以在网络性能模拟器与应用服务器之间的多个箭头进行示意。
S303、终端设备将业务体验质量数据发送给第一网元。
终端设备可以将在第一网络性能场景下进行业务测试的测试结果，例如业务体验质量数据发给第一网元。其中，业务体验质量数据可以包括业务体验质量等级，例如“不可接受等级”、“可接受等级”、“优”、“良”和“中”等的哪一个等级。
S304、应用服务器将业务体验质量数据发送给第一网元。
终端设备使用第一网络性能场景下的网络连接进行业务，可能涉及到与网络中的应用服务器进行交互。如果终端设备与应用服务器进行交互，那么应用服务器也可以获得对该业务的测试结果，例如业务体验质量数据，可以将业务体验质量数据发给第一网元。同样，这里的业务体验质量数据可以包括业务体验质量等级，例如“不可接受等级”、“可接受等级”、“优”、“良”和“中”等的哪一个等级。
S305、终端设备将网络性能指标数据发送给第一网元。
终端设备可以将在第一网络性能场景下进行业务测试的测试结果，例如网络连接的网络性能指标数据发给第一网元。其中，网络性能指标数据可以包括例如终端设备到应用服务器或终端设备之间网络连接的通信带宽、时延、丢包率、误码率等网络性能指标数据。
S306、网络性能模拟器将网络性能指标数据发送给第一网元。
终端设备在网络性能模拟器提供的第一网络性能场景下的网络连接进行业务，那么网络性能模拟器可以获得业务测试结果，例如网络连接的网络性能指标数据，可以将获得的网络性能指标数据发给第一网元。
需要说明的是，S303-S306的执行顺序不作限制。在一些实施例中，可以依次执行S305、S303、S306和S305；或者在另一些实施例中，可以依次执行S306、S303、S305和S304；等等。在一些实施例中，S304和S304只需要执行其中的一个步骤即可，S305和S306只需要执行其中的一个步骤即可，图3以执行S303和S306为例，所以S304和S305用虚线进行示意。
在本申请实施例中，终端设备和应用服务器，设置网络性能模拟器均可以提供与网络性能场景对应的网络数据，对于第一网元而言，可以从终端设备和应用服务器，设置网络性能模拟器获取需要的网络数据。即使例如第一网元从终端设备获取网络数据失败，还可以向应用服务器或网络性能模拟器获取网络数据，可靠性更高。
S202、第一网元根据获得的多组网络数据确定服务等级模型，该服务等级模型用于指示至少一个组合与业务体验质量的等级的对应关系，每个组合对应至少一种网络性能指标。
第一网元针对每个网络性能场景收集一组网络数据，那么针对多个网络性能场景，第一网元收集多组网络数据。第一网元获得多组网络数据中的每一组网络数据中的至少一种网络性能指标数据和对应的业务体验质量等级，可以确定各个网络性能场景下的网络性能指标和业务体验质量等级的关联关系，也可以理解为确定各个网络性能场景下的服务等级。例如该关联关系包括至少一个网络性能指标组合与业务体验质量等级的对应关系。
应理解，每个网络性能指标组合包括至少一种网络性能指标。至少一个网络性能指标组合可以包括网络侧和/或终端设备的网络性能指标组合。例如，存在M个网络性能指标，其中，M为正整数，每个网络性能指标的不同取值，可能对应不同的业务体验质量等级。对于某个网络性能场景来说，可能对应M个网络性能指标中的一个或多个网络性能指标所对应的业务体验质量等级。
在一个示例中，第一网元可以基于深度学习方法，训练预设的模型，该模型的输入为针对每个网络性能场景收集的多组网络数据和业务体验质量等级评估结果。其中每组网络数据包含一到多种网络性能指标的数值，这些网络性能指标数值来自终端设备和/或网元设备在网络性能场景下对网络性能进行测量的结果。业务体验质量等级评估结果为在网络性能场景下终端或应用服务器对业务体验质量评定的结果。第一网元使用网络性能场景下网络数据和业务体验质量等级评估结果，执行聚合算法或回归算法，拟合出至少一个网络性能指标组合与业务体验质量等级的对应关系。聚合算法或回归算法输出至少一个网络性能指标组合与业务体验质量等级的对应关系，从而获得服务等级模型。
该服务等级模型可以指示网络性能指标各种组合与业务体验质量等级的对应关系，基于该服务等级模型，获得当前的网络数据就可以确定当前的网络切片提供的服务等级，从而可以基于该服务等级可以实现多种功能。例如基于该服务等级对当前的网络切片进行管理，或者基于该服务等级对使用当前的网络切片的终端设备的资源进行管理，又或者基于该服务等级对使用当前的网络切片的终端设备进行计费等，下面分别以具体的示例进行说明。
请参见图4，为本申请实施例能够适用的一种示例性的架构，本申请实施例提供的方法还可以应用于其他系统架构中。本领域技术人员可以将图4所示的系统架构中的各个逻辑功能节点的名称更换为其它名称，当执行相同的功能时，属于本申请保护的范围。
图4所示的系统在图1所示的系统的基础上，新增加了服务等级分析单元、服务等级保障单元、服务等级计费单元，其中，服务等级分析单元可以与网络数据分析网元、服务等级保障单元、服务等级计费单元分别连接。服务等级分析网元还可以与网络切片连接，用于收集来自网络切片的网络性能指标数据。服务等级保障单元也可以与网络切片连接，用来调整网络切片，也可以理解为用来管理分配网络切片的资源。
应理解，服务等级分析单元、服务等级保障单元和服务等级计费单元均可以是软件功能，可以部署在某个实体设备，例如部署在网络数据分析网元所在实体设备。服务等级分 析单元、服务等级保障单元和服务等级计费单元也可以是实体设备，实现对应的功能。服务等级分析单元、服务等级保障单元和服务等级计费单元可以对应一个实体设备，也可以对应多个实体设备。例如如果服务等级分析单元、服务等级保障单元和服务等级计费单元对应一个实体设备，那么服务等级分析单元、服务等级保障单元和服务等级计费单元可以认为是该实体设备的三个软件功能模块。下文中，以服务等级分析单元、服务等级保障单元和服务等级计费单元部署在第一网元为例。
基于图4所示的系统架构，在一种应用场景中，第一网元可以基于上述的服务等级模型确定当前的网络切片提供的服务等级，并根据确定的服务等级对分配网络切片的资源进行管理，以尽量保障网络切片的满足KPI。
由于保障网络切片的服务等级实际上是用户使用网络切片的过程中实现的，下面在介绍保障网络切片的服务等级的流程之前，下面介绍用户订购网络切片的流程。
S203、终端设备对服务等级模型进行验证。
例如，终端设备可以发送第一信息，该第一信息例如为终端设备在某个网络性能场景下的网络连接进行业务测试的结果，例如为用于指示终端设备的业务体验质量和/或网络性能指标的网络数据。终端设备可以确认服务等级模型指示的各个网络性能场景和对应的业务体验质量等级是否符合之前对业务测试的测试结果，例如第一信息，如何符合，那么可以确定服务等级模型是正确的。
S204、终端设备确定服务等级模型通过验证，签署该服务等级模型对应的服务等级协议。
服务等级协议可以包括用户使用网络切片时在各个网络性能场景对应的计费标准和/或出现不可接受服务等级对应的网络情况时的赔偿标准等。或者服务等级协议也可以包括违反服务等级协议的责任认定方案。例如当用户终端的业务体验质量等级为不可接受等级时，通过分析用户终端的网络连接的网络性能测量结果、网络侧的网络连接的网络性能测量结果和应用服务器的网络性能测量结果，来确定导致用户终端的业务体验质量等级为不可接受等级的因素是运营商提供的网络切片造成的，还是由用户终端造成的。
在一些实施例中，服务等级协议还可以包括责任认定后，关于服务等级保障的方案。例如如果责任认定的结果是运营商的网络切片造成的，服务等级保障的方案可以包括改变网络切片性能的相关操作。应理解，服务等级协议也可以认为是协议条款。
终端设备确定该服务等级模型是正确的，可以查看该服务等级模型对应的服务等级协议。终端设备如果同意服务等级协议中的某些协议条款，可以选择并同意相应的协议条款后，签署服务等级协议。应理解，签署服务等级协议也可以是签署服务等级模型以及对应的协议条款。
S205、终端设备按照签署的服务等级协议向运营商提交网络切片订单。
运营商的网络切片管理系统根据用户签署的服务等级协议中业务体验质量可接受的业务性能场景，综合当前网络资源的可用数量，其它网络切片订单需求，为当前网络切片订单分配网络资源，生成网络切片。
请参见图5，为保障网络切片的服务等级的流程示意图，该流程的描述如下：
S501、第一网元确定当前的网络切片的服务等级。
当前的网络切片的服务等级可以是当前某个网络切片的服务等级，也可以是终端设备接入的多个网络切片中的部分网络切片的服务等级。第一网元可以根据确定的服务等级模 型确定当前的网络切片的服务等级；或者，第一网元确定了服务等级模型，可以将服务等级模型迁移至第二网元，该第二网元可以根据确定的服务等级模型确定当前的网络切片的服务等级，并将确定的服务等级告知第一网元。应理解，第二网元可以是软件功能，可以部署在网络中的硬件设备，也可以是网络中的硬件设备或者网络之外的硬件设备。
在一个示例中，服务等级分析单元部署在第一网元或第二网元，下面以服务等级分析单元部署在第一网元为例。服务等级分析单元可以根据服务等级模型确定当前网络切片提供的服务等级。具体的，第一网元可以将确定的服务等级模型发送给服务等级分析单元，或者，服务等级分析单元可以从第一网元获取服务等级模型。应理解，服务等级分析单元保存服务等级模型，即服务等级分析单元可以知道网络性能指标各种组合对应的业务体验质量等级，从而可以根据网络切片的网络性能指标确定网络切片提供的服务等级。进一步地，服务等级分析单元可以根据用户的业务体验需求确定网络应该满足的性能指标，以尽量保障网络切片能够提供合理的服务等级。
服务等级分析单元可以根据获取的终端设备的网络性能指标数据和/或网络中的功能网元的网络性能指标数据，结合服务等级模型确定当前网络切片提供的服务等级。例如，第一网元可以获取终端设备的第一信息，根据第一信息中的终端设备的网络性能指标数据和服务等级模型确定当前的网络切片的服务等级；或者第一网元可以获取网络中的功能网元的网络性能指标数据，根据该网络性能指标数据和服务等级模型确定当前的网络切片的服务等级；或者，第一网元根据终端设备的第一信息中的终端设备的网络性能指标数据、网络中的功能网元的网络性能指标数据和服务等级模型确定当前的网络切片的服务等级。
在一个示例中，S501a、应用服务器可以获取多个终端设备的第一信息，并发送给服务等级分析单元。
例如应用服务器可以对获取的多个终端设备的第一信息进行处理，例如汇总第一信息中的网络性能指标数据对应的各个业务体验质量等级中，同一业务体验质量等级的终端设备的数量或者在这个多个终端设备中的占比，并将对应的业务体验质量等级以及各个业务体验质量等级的终端设备的数量或者占比发送给服务等级分析单元。
作为S501a可替换的一种方式，S501b、服务等级分析单元从各个终端设备获取第一信息。
这种方式下，服务等级分析单元可以直接从各个终端设备获取第一信息，并进行处理，即第一信息中的网络性能指标数据对应的各个业务体验质量等级中，同一业务体验质量等级的终端设备的数量或者在这个多个终端设备中的占比。应理解，S501a和S501b可以只执行其中的一个步骤，图5以执行S501b为例，所以S501a在图5中以虚线进行示意。
S501c、服务等级分析单元从网络中的各个网络功能网元获取网络性能指标数据。
网络性能指标数据例如包括带宽、时延、丢包率、误码率、可靠性等网络性能指标数据。示例性的，请参见表3，为网络性能指标(KPI)数据的一种示例。应理解，本申请实施例的KPI数据包括但不限于表3所示的类别和具体样例。目前KPI落到哪个类型范围，对应一种性能场景，对应一种服务等级。本申请实施例中，每个KPI组合均对应特定的服务等级。示例性的，网络性能模拟器存储有网络性能场景与服务等级的对应关系，例如该对应关系以表的形式实现。
表3-网络性能指标数据的一种示例

Figure PCTCN2020107931-appb-000005
服务等级分析单元对获取的终端设备的网络性能指标数据和/或网络中的功能网元的网络性能指标数据进行处理，结合服务等级模型确定当前网络切片提供的服务等级。
例如，如果服务等级分析单元获取的是终端设备的业务体验质量数据，服务等级分析单元可以按照用户或终端设备的位置信息，例如小区(cell)标识(identity，ID)或跟踪区标识(tracking area identity，TAI)将业务体验质量数据分成几组。如果服务等级分析单元获取的是网络性能指标数据，服务等级分析网元可以按照这些网络性能指标数据归属的用户或终端设备的位置信息或这些网络性能指标数据归属的网络功能的区域信息，例如这些网络性能指标数据归属接入和移动性管理功能(access and mobility management function，AMF)区域，会话管理功能(session management function，SMF)服务区域或(user plane function，UPF)服务区域等分成几组。服务等级分析单元将同一位置区域的业务体验质量数据、网络性能指标数据进行关联分别对各个位置区域的数据进行处理，获得当前网络性能指标的组合。进而根据当前网络性能指标的组合以及服务等级模型确定当前的网络切片的服务等级。
例如，如果使用当前的网络切片的终端设备为一个终端设备，例如第一终端设备，那么服务等级分析单元根据第一终端设备的网络性能指标或功能网元的网络性能指标、以及服务等级模型确定当前的网络切片提供的服务等级，例如第一服务等级。
如果使用当前的网络切片的终端设备为多个终端设备，那么服务等级分析网元可以根据这多个终端设备的网络性能指标或功能网元的网络性能指标、以及服务等级模型确定第一服务等级。再根据各个业务体验质量等级的终端设备的数量或者根据各个业务体验质量等级的终端设备在这多个终端设备中的占比对第一服务等级进行修正，获得当前的网络切片提供的第二服务等级。
S502、服务等级分析单元确定当前的服务等级不满足预设条件时，对当前的网络切片或者使用当前的网络切片的部分终端设备的资源进行管理。
预设条件至少包括“可接受等级”，例如预设条件为“可接受等级”，或者接近“可接受等级”。在一个示例中，终端设备可以上报当前的服务等级是否满足的信息，以便服务等级分析单元确定当前的服务等级是否满足预设条件。
例如，S502a、终端设备向应用服务器发送第一事件，该第一事件用于指示当前的服务等级不可接受。
在一些实施例中，终端设备的业务体验质量的等级低于某个等级时，可以向应用服务器发送第一事件，用于表示当前的服务等级不可接受。该第一事件也可以称为体验劣化事件。该第一事件可以包括终端设备的位置信息，应用服务器接收该第一事件，将该第一事件发送给服务等级分析单元。
作为S502a可替换的方案，S502b、终端设备向服务等级分析单元发送第一事件，该第一事件用于指示当前的服务等级不可接受。应理解，S502a和S502b可以只执行其中的一个步骤，图5以执行S502b为例，所以S502a在图5中以虚线进行示意。
服务等级分析单元根据接收的第一事件，确定位于某网络位置的网络切片的服务等级接近或达到不可接受级别，或者确定使用位于某网络位置的网络切片的部分终端设备的服务等级接近或达到不可接受级别，则确定当前的服务等级不满足预设条件。
服务等级分析单元在确定当前的服务等级不满足预设条件时，可以根据当前可用的网 络资源、当前的各个网络切片的优先级，以及其它网络切片的资源需求信息，对当前的网络切片进行管理，或者对使用当前的网络切片的部分终端设备的资源进行管理。
示例性的，S502c、服务等级分析单元可以向服务等级保障单元发送第一请求消息，该第一请求消息用于请求保障服务等级。该第一请求消息可以包括网络切片的标识信息、网络位置以及部分终端设备的标识信息，其中网络位置可以是网络切片所在网络的位置，也可以是终端设备所在的位置。服务等级保障单元接收该第一请求消息，根据当前可用的网络资源、当前的各个网络切片的优先级，以及其它网络切片的资源需求信息，确定为当前的网络切片分配更多的网络资源，或者确定为使用当前的网络切片的部分终端设备分配更多的网络资源，以改变当前网络切片的网络性能，尽量保障合理的服务等级。由于本申请实施例根据网络运行情况可以适应性调整为当前的网络切片或者部分终端设备分配更多的网络资源，相较于目前不支持服务等级不可调，可以弹性保障服务等级。
在另一个示例中，第一网元可以基于确定的当前的网络切片的服务等级，通知服务等级计费单元对使用网络切片的终端设备进行计费。
S503、服务等级分析单元向服务等级计费单元发送第二请求消息，该第二请求消息包括当前的服务等级，用于请求对使用当前的网络切片的终端设备进行计费。
服务等级计费单元接收第二请求消息，根据第二请求消息包括的当前的服务等级，对使用当前的网络切片的终端设备进行计费。如果使用当前的网络切片的终端设备为一个，也就是使用当前的网络切片的用户为个人用户，那么服务等级计费单元根据例如前述的第一服务等级对个人用户进行计费。如果使用当前的网络切片的终端设备为多个，也就是使用网络切片的用户为企业或组织，那么服务等级计费单元根据例如前述的第二服务等级对企业或组织进行计费。
在一种可能的应用场景，例如用户观看视频时，由于网络较差，视频可以从高清模式切换到流畅模式，目前针对高清模式的计费和流畅模式的计费是一致的。而高清模式的计费更贵才比较合理，由于本申请实施例可以弹性保障服务等级，相较于目前不支持按照变化的服务等级进行计费，更为合理。
作为如上各个实施例的一种可替换的方案，在另一种可能的应用场景中，本申请实施例基于区块链实现上述各个实施例，以尽量保证数据的安全性。为了便于理解本申请实施例提供的技术方案，下面首先介绍区块链的相关技术。
区块链(blockchain)是一种以区块(block)为单位产生和存储数据，并按照时间顺序将数据区块以顺序相连的方式组合成的一种链式数据结构，并以密码学方式保证的不可篡改和不可伪造的分布式账本。区块链系统包括多个节点，每个节点都可以创建区块，多个节点所创建的区块按照时间戳顺序形成数据链，每个区块链上的数据具有关联性。每个区块的创建需要得到大多数节点的共识确认，并向区块链系统中的各节点广播以实现全网同步。区块链系统中的所有节点共同参与区块链系统中的数据的验证、存储和维护。某些参与节点在数据源节点授权允许的条件下，可以从数据链获得区块存储的数据，从而实现数据有控制的共享，保障数据不被篡改。区块链具有多方共识和透明可追溯的特点，本申请实施例使用区块链技术可以实现网络服务和计费的公正和透明。
智能合约技术是运行在区块链基础上的一种特殊协议，当区块链的数据满足约定条件后，就会执行协议包含的代码，能够自动处理数据信息或者接受、存储或发送价值(即区块链技术的数字货币)。
合约链是基于数字货币系统开发的支持智能合约的应用级区块链。本申请实施例将合约链用于网络的服务等级协议的签署、针对使用网络切片的终端设备的计费以及违反服务等级协议的违约赔偿。
预言机(oracle)，为将区块链外的信息写入区块链内的机制，可以将外界信息写入到区块链内，完成区块链与现实世界的数据互通。预言机允许确定的智能合约对不确定的外部事件作出反应，是智能合约与外部进行数据交互的唯一途径，也是区块链与现实世界进行数据交互的接口。
在本申请实施例中，数据链和合约链可以以公有云形式提供区块链公共服务。请参见图6，为本申请实施例适用的一种区块链场景下的系统架构。图6也可以认为是图1以区块链实现的一种形式，图1包括的网络性能模拟器、应用服务器和网络数据分析网元为区块链系统中的节点，也就是网络性能模拟器、应用服务器和网络数据分析网元是使用区块链服务的节点。在一个示例中，应用客户端(终端设备)可以安装网络测量插件，该网络测量插件能够使得应用客户端使用区块链服务，也就是使得应用客户端也能够成为区块链系统的节点。同时，该网络测量插件还可以测量应用客户端的网络连接的网络性能。其中网络测量插件可以是运营商或者区块链公有云服务的第三方提供的。
在区块链的应用场景下，公有云服务可以是第三方提供的，可以以公有云为平台提供数据链服务和合约链服务。应理解，这里的第三方可以提供网络切片服务的运营商，也可以是独立该运营商的第三方。
网络性能模拟器可以是运营商提供的，例如网络性能模拟器可以是运营商提供的公有云中的组件。这种情况下，应用服务器可以部署在公有云，应用客户端可以通过接入公有云访问应用服务器，并使用网络性能模拟器。
与前述实施例类似，应用客户端可以使用网络性能模拟器提供的网络性能场景实现应用客户端到应用服务器或者应用客户端之间的网络连接，其中网络连接的带宽、时延、丢包率、误码率、可靠性等网络性能指标参数匹配要接入的网络性能场景。应用客户端在设定的网络性能场景下进行业务测试。
针对每一个网络性能场景，应用客户端、网络模拟器和网络数据分析网元可以将交互的信息发布到区块链系统中的数据链，这样该区块链系统中的参与节点需要获取对应的信息可以从数据链直接获取。
例如，应用客户端在某个网络性能场景下的网络连接进行业务，利用网络测量插件可以获得该业务的测试结果，例如前述的第一信息。应用客户端可以将第一信息发布到区块链系统的数据链，例如第一数据链。同理，网络性能模拟器可以收集某个网络性能场景下的多个终端设备和应用服务器之间的网络连接的网络性能指标数据发布到区块链系统中的例如第二数据链。同理，应用服务器可以将获得的业务的测试结果，例如前述的第二信息发布到区块链系统中的例如第三数据链。应理解，针对每个网络性能场景对应的业务测试结果，也就是前述的网络数据(第一信息和/或第二信息)均存储在区块链系统中的数据链，也就是区块链系统中的至少一条数据链至少用于存储来自终端设备的第一信息或来自应用服务器的第二信息。其中，应用客户端、应用服务器和网络性能模拟器获取某个网络性能场景下的某个业务的测试结果可以参考前述实施例的相关介绍，这里不作赘述。
针对每个网络性能场景，网络数据分析网元可以从区块链系统中的至少一条数据链获取一组网络数据，从而网络数据分析网元获得多组网络数据。网络数据分析网元基于获得 的多组网络数据可以获得服务等级模型，具体的可以参见前述实施例的相关介绍，这里不再赘述。
在一个示例中，网络数据分析网元可以将服务等级模型发布到区块链系统包括的数据链，从而其他网元也可以使用该服务等级模型。例如，应用客户端、运营商或者公有云服务的提供商，又或者行业用户等都可以从数据链上获取该服务等级模型。
由于区块链具有多方共识和透明可追溯的特点，所以前述终端设备验证服务等级模型可以获取各个网络性能场景下的网络连接的终端设备的网络性能、网络侧的网络性能和终端设备的业务体验质量等级，确定各个网络性能场景下的网络连接的终端设备的网络性能、网络侧的网络性能和终端设备的业务体验质量等级的关联关系是否是正确的。例如如果参与节点对上述的关联关系达成共识，那么可以认为该服务等级模型是正确的。
作为上述终端设备确定服务等级模型通过，签署该服务等级模型对应的服务等级协议的一个可替换方案，前述的服务等级协议均可以有对应的智能和合约的执行代码。从而终端设备可以根据服务等级协议的执行代码和服务等级模型生成智能合约，并将智能合约发布到区块链系统中的合约链。
请参见图7，为生成智能合约的一种示例。在本申请实施例中，网络数据分析网元可以作为预言机，收集网络内各个功能网元，例如终端设备、应用服务器和网络性能模拟器中的一种或多种的组合的网络性能测量数据，导入合约链。
在一个示例中，合约链中存在第一智能合约，该第一智能合约用于指示按照第二服务等级对使用当前的网络切片的终端设备进行计费。网络数据分析网元可以从数据链获取至少一个第一信息或第二信息，也就是来自至少一个终端设备的网络数据或至少来自应用服务器的网络数据，以及使用在数据链中发布的服务等级模型，确定的当前的网络切片的服务等级，例如第二服务等级，然后将确定的结果导入合约链。其中当前的网络切片的服务等级可以认为是计费事件的数据，传递到合约链，触发第一智能合约，实现对使用当前的网络切片的终端设备进行计费。
在另一个示例中，合约链中存在第二智能合约，该第二智能合约用于指示确定终端设备的网络连接是否正常。网络数据分析网元可以从数据链获取至少一个第一信息或第二信息，也就是来自至少一个终端设备的业务体验质量等级或至少来自应用服务器的业务体验质量等级，在确定终端设备相关的业务体验质量等级低于某个等级，例如第一等级，向第二智能合约注入第一事件，该第一事件包括至少一个第一信息。应理解，第二智能合约的执行代码和至少一个第一信息可以确定终端设备的网络连接是否正常。其中网络数据分析网元将第一事件传递到合约链，触发第二智能合约，实现根据当前的网络性能数据以及第一事件确定终端设备的网络连接是否正常。网络数据分析网元还可以根据确定结果生成第二事件，该第二事件用于指示网络异常或者终端设备异常。网络数据分析网元还可以将该第二事件注入第二智能合约。或者，在一些实施例中，网络数据分析网元还可以将该第二事件注入例如第三智能合约，该第三智能合约用于指示执行责任认定。应理解，该第二事件也可以认为是责任认定事件，用于触发责任认定方案。
下面就基于图6所示的系统架构，本申请实施例所涉及的一些子方案分别进行举例介绍。
请参见图8，为系统中功能网元与数据链、合约链之间的关系示意图。
在应用客户端使用网络切片的过程中，网络数据分析网元作为预言机，可以将获取的 网络内的各个功能网元的网络性能测量数据，例如前述的第一信息和/或第二信息，导入到合约链中。另外，当应用客户端或应用服务器不具备预言机功能时，网络数据分析网元还可以获取应用客户端或应用服务器的业务体验质量数据，承担预言机的角色，将获取的业务体验质量数据导入到合约链中。服务等级分析单元可以根据各个功能网元的网络性能测量数据，例如应用客户端或应用服务器的业务体验质量数据，以及服务等级模型，评估当前的网络切片的服务等级，并将服务等级导入到合约链中。在一些实施例中，应用客户端的网络测量插件也可以承担预言机角色，将单个应用客户端的网络连接的网络性能测量数据导入到合约链中。
图9所示，为确定网络切片服务等级并进行计费的流程，具体流程描述如下：
S901、应用服务器获取各个终端设备的业务体验质量数据，并发布到数据链。
应用服务器可以获取各个终端设备的业务体验质量数据，将业务体验质量数据发布到数据链。或者可以将获取的业务体验质量数据进行处理，例如将属于同一业务体验质量等级的业务体验质量数据汇总，再发布到数据链。如果应用服务管理器没有区块链功能，也可以发给网络数据分析单元，由具备预言机功能的网络数据分析单元将各个终端设备的业务体验质量数据发布到数据链。由于各个终端设备的业务体验质量数据存储在数据链，服务等级分析单元可以从数据链获得需要的业务体验质量数据。
S902、网络数据分析网元从网络中的各个功能网元获取网络性能指标数据，发布到数据链。
由于各个功能网元的网络性能指标数据存储在数据链，服务等级分析单元可以从数据链获得需要的网络性能指标数据。
S903、终端设备安装的网络测量插件测量各个终端的网络连接的网络性能指标，并将测量的网络性能指标数据发布到数据链。
网络测量插件可以测量各个终端设备的网络连接的网络性能指标，如果网络测量插件不具备区块链功能，也可以将测量的网络性能指标数据发送给网络数据分析单元，由具备预言机功能的网络数据分析单元将该网络性能指标数据发布到数据链。网络数据分析单元或服务等级分析单元可以从数据链获得各个终端设备的网络连接的网络性能指标数据。图9以虚线示意服务等级分析单元可以从数据链获得各个终端设备的网络连接的网络性能指标数据。
S904、服务等级分析单元根据确定当前的网络切片的服务等级。
服务等级分析单元可以根据上述S901-S903获得的例如业务体验质量数据和/或网络性能指标数据确定各个业务体验质量等级的终端设备的数量或者占比，按照服务等级模型确定当前的网络切片的服务等级。
S905、服务等级分析单元计费事件传递给合约链，触发第一智能合约，该计费事件包括确定的服务等级。
服务等级分析单元作为预言机功能，可以将确定的服务等级作为例如计费事件的数据，传递到合约链，触发智能合约。
S906、第一智能合约的执行代码根据计费事件和当前的网络切片的服务等级进行计费。
第一智能合约会自动触发应用客户端的区块链价值转移给提供网络切片服务的运营商，完成计费交易。不同的服务等级的费率可能不同，本申请实施例可以根据当前的网络切片的服务等级对应的费率，进行计费，更为合理。
应理解，每当用户的业务体验质量变化，或网络性能变化时，网络切片的服务等级会相应改变，在本申请实施例中，第一智能合约会自动触发，即自动按照新的服务等级以及对应的费率进行计费。
关于图9所示的流程中的步骤的一些具体实施细节，均可参考图5所示的实施例的相关描述，这里不再赘述。
图10所示，为网络切片的服务等级的保障流程和服务等级的违约赔偿流程，具体流程描述如下：
S1001、网络数据分析网元从网络中的各个功能网元获取网络性能指标数据，发布到数据链。
由于各个功能网元的网络性能指标数据存储在数据链，服务等级分析单元可以从数据链获得需要的网络性能指标数据。
S1002、网络数据分析网元获取各个终端设备的业务体验质量数据，并发布到数据链。
应理解，各个终端设备的业务体验质量数据也可以由网络测量插件直接发布到数据链。网络数据分析网元和服务等级分析单元都可以从数据链获得各个终端设备的业务体验质量数据。当然，各个终端设备的业务体验质量数据也可以由网络测量插件发送给网络数据分析网元和服务等级分析单元(图10以虚线进行示意)。
S1003、应用服务器或网络数据分析网元作为预言机，向智能合约注入第一事件。
应理解，应用服务器或网络数据分析网元当确定业务体验质量等级低于某个等级，也就是业务体验质量劣化时，可以给智能合约注入第一事件，该第一事件可以包括业务体验质量数据。图10分别以实线和虚线示意应用服务器或网络数据分析网元给智能合约注入第一事件。
S1004、第一事件触发智能合约，启动责任认定分析动作，并将认定结果，例如第二事件通知网络数据分析网元进行责任认定。
S1005、网络数据分析网元根据第二事件确定终端设备的网络连接是否正常，获得责任认定结果。
应理解，网络数据分析网元根据S1001中的网络性能指标数据、S1001中的业务体验质量数据，以及结合其他同样位置的终端设备的网络性能测量结果，确定终端设备的网络连接是否正常。如果异常，那么可以确认终端设备的体验劣化是由网络连接造成的；相反，如果正常，那么可以认为终端设备的体验劣化是由终端设备或应用服务器造成的。
S1006、网络数据分析根据责任认定结果产生责任认定事件，将责任认定事件注入智能合约。
S1006a、智能合约的代码确定责任认定结果为应用服务器问题，则通知应用服务器，应用异常。
智能合约的代码判断责任认定事件，如果责任认定结果为应用服务器问题，则通知应用服务器，用户的业务异常。之后可以停止后续步骤。
S1006b、智能合约的代码确定责任认定结果为网络连接问题，则通知服务等级分析单元发生网络异常，继续执行后续步骤。
S1007、如果发生网络异常，服务等级分析单元确定当前网络切片的服务等级。
