Description

一种事件上报的方法、装置及系统 技术领域
本申请涉及无线通信技术领域，特别涉及一种事件上报的方法、装置及系统。
背景技术
随着通信传输技术的飞速发展，尤其在引入第五代移动通信技术(5th generation mobile networks或5th generation wireless systems、5th-Generation，5G)后，越来越注重信息传递的速度以及信息传递的时效性。
其中，为了更好的提升信息传递的时效性，在5G网络中引入边缘计算技术，即在离网关较近的位置上设立边缘计算平台，使边缘计算平台与运营商的5G系统结合，通过所述边缘计算技术在移动网络的边缘提供云端计算能力，从而使得终端可以通过较短的物理距离与本地服务器进行交互，无需访问远端服务器，从而减少延迟获得更好的服务体验，达到服务效率最大化。同时远端服务器只需处理由边缘计算平台处理后的少量数据，减少网络负载。
但是，在通信传输过程中，下一代无线接入网络(Next Generation Radio Access Network，NG-RAN)经常需要将服务质量通知控制(QoS notification control，QNC)事件的上报消息发送至应用功能(Application Function，AF)。而在5G系统引入边缘计算技术的背景下，所述AF可能布置在边缘计算平台上，则所述NG-RAN在向所述AF发送所述事件上报消息时，一种方式可以如图1中实线路径所示，所述NG-RAN需要将所述事件的上报消息经由无线接入网络(Radio Access Network，RAN)、验证管理功能(Authentication Management Function，AMF)、会话管理网元(Session Management Function，SMF)、策略控制网元(Policy Control Function，PCF)、网络功能开放网元(Network Exposure Function，NEF)发送至应用功能(Application Function，AF)。而该种方式进行事件上报消息发送过程中，需要经由网络部署位置较高的PCF和NEF再回到边缘计算平台上的AF，引入额外的传输时延，降低事件上报消息的时效性。另一种方式可以如图1中虚线路径所示，所述NG-RAN将所述事件的上报消息使用用户面路径通过用户面网元(User Plane Function，UPF)向AF发送。但是，现有通过配置用户面路径发送事件对应的上报消息的方案无法防止攻击者向AF发送虚假消息或者攻击者对UPF与AF之间路径实施中间人攻击，例如，攻击者可向AF发送伪造的事件上报内容或重复其他UPF发送的事件上报消息来影响AF为用户服务。再例如，攻击者可以通过重放或篡改之前的事件上报消息来干扰AF为用户服务。
综上所述，目前并没有安全且时效性较强的事件上报方法。

具体实施方式
目前，通过用户面路径发送事件对应的上报消息的方案如图2所示，由应用侧AF将本地事件对应的上报需求(其中包含是否需要和/或支持用户面通知)通过AF请求(Request)流程，经由AF、NEF、UDR发送至PCF(也可直接发送至PCF)。PCF根据AF的请求生成策略控制和计费(Policy Control and Charging，PCC)规则，其中包含对某事件使用用户面上报的指示，PCF将该PCC规则告知SMF，SMF根据PCF通知配置用户面路径上的NG-RAN和UPF，使得NG-RAN和UPF可以使用用户面直接将需要进行上报的事件对应的上报消息发送给所述AF侧。
但是，上述通过用户面路径发送上报消息的方案无法防止攻击者向AF发送虚假消息或者攻击者对UPF与AF之间路径实施中间人攻击，例如，攻击者可向AF发送伪造的事件上报内容或重复其他UPF发送的事件上报消息来影响AF为用户服务。再例如，攻击者可以通过重放或篡改之前的事件上报消息来干扰AF为用户服务。
为解决该问题，本申请实施例提供一种事件上报的方法。本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，未来的第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，及未来的通信系统，如6G系统等。
以5G系统(也可以称为New Radio系统)为例，具体来说，5G系统中定义了新的通信场景：超高可靠低时延通信(Ultra-Reliable and Low-Latency Communication，URLLC)、增强移动宽带(Enhanced Mobile Broadband，eMBB)和海量机器连接通信(Massive Machine Type Communication，mMTC)，这些通信场景对通信信息传递的时效性以及安全性有更严苛的需求。因此在引入边缘计算技术的场景下，AF布置在离用户终端设备和本地用户面网元UPF更近的边缘计算平台上，而非集中化部署在网络中较高的位置，因此网络在向AF传输事件对应的上报消息的过程中，需要考虑所述AF接收到的上报消息的时效性以及安全性。
基于网络侧通过用户面网元UPF向AF发送上报消息，以此保证所述上报消息的时效性的前提下，为了更好的保证AF接收到的所述上报消息的安全性，本申请实施例提出了一种事件上报的方法，通过该方法，所述用户面网元UPF向所述AF发送的上报消息需要由所述AF进行权限验证，若通过所述权限验证，则所述AF才会获取所述上报消息，反之，所述核心网设备丢弃所述上报消息。
由于在该方法中所述AF对接收到的所述上报消息进行权限验证，且所述AF仅获取通过所述权限验证的上报消息，从而可以防止攻击者通过上报消息对所述AF进行安全攻击，保证所述用户面网元UPF与所述AF通信的安全性。
为便于理解本申请实施例，首先以图3中示出的通信系统为例详细说明本申请实施例适用的通信系统。如图1所示，该通信系统包括边缘计算平台300、核心网设备310和业务服务器320。
边缘计算平台300，是一种用于在移动网络的边缘提供云端计算能力的网络平台。其中，所述边缘计算平台被设立在离网关较近的位置上，使得用户端可以通过较短的物理距离与服务器进行交互，无需访问远端的服务器，从而减少延迟获得更好的服务体验。同时远端服务器只需处理由边缘计算平台处理后的少量数据，减少网络负载。
核心网设备310从协议上规定就是起到核心交换或者呼叫路由功能的网元，主要作用是提供用户连接、对用户管理以及整个呼叫信令控制和承载建立。
其中，本申请实施例中所述核心网设备可包括：
(1)验证管理功能(AuthenticationManagementFunction，AMF)网元；
(2)统一数据管理(Unified data management，UDM)网元，所述UDM网元用于存储所述核心网设备的信息；
(3)开放功能网元，所述开放功能网元用于在接收到所述业务服务器发送的获取事件的上报消息的请求后，通知SMF网元进行用户面路径配置。其中，在4G网络中，开放功能网元可以为业务能力开放网元(service capability exposure function，SCEF)，在5G网络中，开放功能网元可以为网络开放功能网元(network exposure function，NEF)，在未来通信如6G通信中，开放功能网元仍可以是NEF网元，或者有其它名称，本申请对此不作限定。
(4)策略控制网元(Policy Control Function，PCF)；
(5)会话管理网元(Session Management Function，SMF)；
(6)用户面网元(User Plane Function，UPF)；
(7)下一代无线接入网络(Next Generation Radio Access Network，NG-RAN)。
业务服务器320，可以根据业务需求向开放功能网元请求获取终端或终端群组的事件上报消息，并将终端或终端群组的发送的所述事件上报消息，上报给目标地址。其中，目标地址可以是业务服务器的地址，也可以是其它服务器的地址，还可以是3GPP网络中的其它网元的地址。目标地址可以根据终端或终端群组的发送的所述事件的上报消息确定终端状态，从而为终端提供业务服务。在4G网络中，业务服务器可以是业务能力服务器/应用服务器(service capability server/application server，SCS/AS)，在5G网络中，应用功能(application function，AF)。6G通信中，业务服务器仍可以是AF，或者有其它名称，本申请对此不作限定。
其中，所述业务服务器可将物理部分或者逻辑部分放置到所述边缘计算平台300中。
在本申请实施例中，终端群组包括多个终端，业务服务器可以通过终端群组标识请求对该终端群组中所有终端的监控，开放功能网元在向目标地址上报终端群组的事件上报消息时，可以以终端群组为单位，将终端群组中多个终端的事件上报消息统一上报给目标地址。在一种终端群组的具体实例中，终端可以为UE，终端群组可以为一组UE(a group of UEs)。
本申请实施例描述的网络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，随着网络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。应理解，图3仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他业务服务器以及其他终端设备等，图3中未予以画出。
以下再对本申请实施例中涉及的部分用语进行解释说明，以便于理解。
1)边缘计算，是指在靠近物或数据源头的一侧，采用网络、计算、存储、应用核心能力为一体的开放平台，就近提供最近端服务。其应用程序在边缘侧发起，产生更快的网络服务响应，满足行业在实时业务、应用智能、安全与隐私保护等方面的基本需求。边缘计算处于物理实体和工业连接之间，或处于物理实体的顶端。而云端计算，仍然可以访问边缘计算的历史数据。
对物联网而言，边缘计算技术取得突破，意味着许多控制将通过本地设备实现而无需交由云端，处理过程将在本地边缘计算层完成。这无疑将大大提升处理效率，减轻云端的负荷。由于更加靠近用户，还可为用户提供更快的响应，将需求在边缘端解决。
2)重放，是指攻击者发送一个目的主机已接收过的包，来达到欺骗系统的目的。重放攻击可以由发起者，也可以由拦截并重发该数据的敌方进行。
3)传输层安全性协议(Transport Layer Security，TLS)，及其前身安全套接层(Secure Sockets Layer，SSL)，是一种安全协议，目的是为互联网通信提供安全及数据完整性保障。目前已成为互联网上保密通信的工业标准。TLS协议采用主从式架构模型，用于在两个应用程序间透过网络创建起安全的连线，防止在交换数据时受到窃听及篡改。
另外，本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“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的情况，其中，A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种 “或”的关系。以下至少一项(个)下或其类似表达，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)，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。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
此外，本申请实施例和权利要求书及附图中的术语“包括”和“具有”不是排他的。例如，包括了一系列步骤或模块的过程、方法、系统、产品或设备，不限定于已列出的步骤或模块，还可以包括没有列出的步骤或模块。
