为了使得本公开的目的、技术方案和优点更为明显,下面将参照附图详细描述根据本公开的示例实施例。显然,所描述的实施例仅仅是本公开的一部分实施例,而不是本公开的全部实施例,应理解,本公开不受这里描述的示例实施例的限制。
首先,参照图1描述应用根据本公开实施例的网络数字孪生构建方法的场景。
根据本公开实施例的网络数字孪生构建方法用于在通信网络管理系统中引入数字孪生体,以模拟端到端网络整体的运行环境和运行状态,同时与各网络实体之间进行实时交互。网络实体的各类运行信息可以实时输入给数字孪生体,构建网络数字孪生服务。构建网络数字孪生需要与网络管理系统互通,将物理实体中对应的相关网络业务及网元配置下发给孪生网络中的各个网元,虽然沿用原有网络资源模型,但同样需要创建网络功能管理对象实例(Managed Object Instance,MOI)。网络数字孪生可以模拟真实物理通信网络中的所有操作,并且具有分析和预测未来通信网络状况和性能的能力。例如,可以将深度学习和机器学习等一些人工智能模型引入到整个网络数字孪生系统中,以辅助网络管理优化、网络预测、容量规划等。通过对网络数字孪生中的网络服务进行建模,训练数据可以通过物理实体的输入信息不断补充和更新到模型中,在网络数字孪生模型内部形成自适应机制,实现更精确的闭环网络运行和维护。
如图1所示,根据本公开实施例的网络数字孪生构建方法生成的网络数字孪生功能管理对象实例10可以是响应于管理数据分析(Management Data Analytics,MDA)管理服务(Management Services,MnS)消费方20的请求而构建的。管理数据分析(MDA)管理服务(MnS)生产方30则可以提供用于构建网络数字孪生功能管理对象实例10所对应的网元的相关信息。此外,网络数字孪生功能管理对象实例10还可以与其他MnS生产方40和非3GPP管理系统50等实体进行交互。
以下,将进一步参照图2到图4描述根据本公开实施例的网络数字孪生构建方法。
图2是图示根据本公开实施例的网络数字孪生构建方法的流程图。如图2所示,在步骤S201中,向第一网元发送查询请求。
在本公开的实施例中,由网络数字孪生管理功能(NDT_MF)网元向第一网元发送查询请求。第一网元可以是管理数据分析系统(MDAS)网元或者网络功能管理功能(Network FunctionManagement Function,NFMF)网元。
在第一网元是管理数据分析系统(MDAS)网元的情况下,查询请求用于查询管理数据分析系统(MDAS)网元的管理对象的信息,所述管理对象即目标网元。查询请求可以包括该目标网元的网元标识,或者目标网元所属网络切片的网络切片标识。
在第一网元是网络功能管理功能(NFMF)网元的情况下,查询请求用于查询网络功能管理功能(NFMF)网元的管理对象的信息,所述管理对象即目标网元。查询请求可以包括该目标网元的网元标识,或者目标网元所属网络切片的网络切片标识。
查询请求用于获取公共陆地移动网(PLMN)、单个网络切片选择辅助信息(SNSSAI)、数据网络名称(DNN)或者虚拟网络内网组粒度的用户信息。
在步骤S202中,从第一网元接收目标网元的相关信息。
在本公开的实施例中,从第一网元接收的目标网元的相关信息包括目标网元的网络模型信息、网络模型信息所对应的网络参数信息等。网络模型信息例如包括服务配置信息、网络切片配置信息。网络参数信息例如包括网络功能对应的管理对象实例的参数及其取值。
更具体地,网络模型包括基础模型和功能模型两个类别。基础模型是指基于网元基本配置、环境信息、运行状态、链路拓扑等信息,建立的对应于物理实体网络的孪生网络体的网元模型和拓扑模型,实现对物理网络的实时精确描述。功能模型是指针对特定的应用场景,充分利用数据仓库中的网络数据,建立的为提供网络分析、仿真、诊断、预测、保障等各种模型。
功能模型可按网络类型构建,可以有服务于单网络域(如移动接入网、传输网、核心网、承载网等)的模型或者服务于多网络域的模型。
功能模型可以按照功能类型构建,可构建状态监测、流量分析、安全演练、故障诊断、质量保障等模型。
功能模型可以按照适用范围构建,可以分为通用模型和专用模型。
功能模型可以按照网络生命周期管理构建,可分为规划、建设、维护、优化和运营等模型。
各功能模型可互相结合,可以构建为服务更为具体业务场景的数据模型,如基于数字孪生的信令风暴控制、基于数字孪生的网络服务服务级别协议保障、网络云跨层透视子场景、高危操作仿真子场景、网络云资源部署优化自场景。
在步骤S203中,基于目标网元的相关信息,生成对应于目标网元的网络数字孪生功能管理对象实例。
在本公开的实施例中,对应于目标网元的网络数字孪生功能管理对象实例的配置与目标网元的实际配置相同。也就是说,通过网络数字孪生功能管理对象实例可以实时与实际网络进行交互。
根据本公开实施例的网络数字孪生构建方法能够实现通过数字孪生技术根据不同需求场景,进行网络数字孪生构建,以实现网络数字孪生对于实际网络的全生命周期管理、全网可视化、仿真预测、闭环控制以及服务级别协议保障等能力。根据本公开实施例的网络数字孪生构建方法支持构建由各种物理设备(如主机、路由器、交换机等)和介质(光纤电缆、电缆、双绞线等)连接在一起形成的5G网络/网络切片。根据本公开实施例的网络数字孪生构建方法可以集成网络管理系统中的所有现有数据,基于实时数据和离线历史数据创建一个准确的网络数字孪生模型,该模型可以数字显示网络基础设施的运行状态和健康状态,包括物理网络设备、逻辑网络设备、端口、链路等。更具体地,根据本公开实施例的网络数字孪生构建方法以模拟全规模的物理网络或仅模拟其中的一部分。
图3是图示根据本公开实施例的一种网络数字孪生构建方法的示意图。图4是图示根据本公开实施例的一种网络数字孪生构建方法的流程图。
如图3所示,MDAMnS消费方301在S1中向NDT_MF 302发出网络功能管理对象实例(MOI)请求。图3中的S1对应于图4所示的步骤S401,即接收网络数字孪生功能管理对象实例的创建或调整请求。也就是说,在该网络数字孪生功能管理对象实例不存在的情况下,网络功能管理对象实例(MOI)请求用于创建网络数字孪生功能管理对象实例。在该网络数字孪生功能管理对象实例存在的情况下,网
络功能管理对象实例(MOI)请求用于调整网络数字孪生功能管理对象实例。
进一步地,如图3所示,NDT_MF 302在S2中向MDAS 303或NFMF 304发起与网络功能管理对象实例(MOI)请求对应的查询请求。图3中的S2对应于图4所示的步骤S402,即向第一网元发送查询请求。第一网元可以为MDAS 303或NFMF 304。查询请求用于查询MDAS 303或NFMF 304的管理对象的信息,所述管理对象即目标网元。查询请求可以包括该目标网元的网元标识,或者目标网元所属网络切片的网络切片标识。
进一步地,如图3所示,MDAS 303或NFMF 304在S3中向NDT_MF 302返回响应于S2中查询请求的查询结果。图3中的S3对应于图4所示的步骤S403,即从第一网元接收目标网元的相关信息。从第一网元接收的目标网元的相关信息包括目标网元的网络模型信息、网络模型信息所对应的网络参数信息等。网络模型信息例如包括服务配置信息、网络切片配置信息。网络参数信息例如包括网络功能对应的管理对象实例的参数及其取值。
进一步地,如图3所示,NDT_MF 302在S4中向MDAMnS消费方301返回响应于S1中网络功能管理对象实例(MOI)请求的结果。图3中的S4对应于图4所示的步骤S404到S406。在步骤S404中,基于目标网元的相关信息,生成网络数字孪生功能管理对象实例的配置参数。在步骤S405中,进行配置验证判断,即判断基于步骤S404中生成的配置参数是否可以实现对应的功能。例如,输入参数列表中的各参数值,基于网络数字孪生的内部逻辑,获取预期结果。如果在步骤S405中确定网络功能不可行(即,例如网络数字孪生输出的预期结果与真实网络对应的实际结果相差大于预定阈值),则返回步骤S404以调整生成网络数字孪生功能管理对象实例的配置参数。如果在步骤S405中确定网络功能可行,则在步骤S406中生成对应于目标网元的网络数字孪生功能管理对象实例。
