背景技术
随着移动网络新业务出现和网络规模持续扩大，网络运营和维护复杂度高，创新技术面临研发周期长和落地部署困难的问题。因此，数字孪生被认为是6G网络的重要方向之一，为移动网络提供全生命周期的规划、研发验证、智慧运维和智能自治。
移动网络端到端包括核心网、传输网、无线接入网和终端等功能，建立端到端的数字孪生体复杂度高。一方面网络级数字孪生体的建模难度随着网络规模和场景丰富度而增大，另一方面移动网络的空口信道、业务特征和用户移动性具有时变性，因此可以预知移动网络数字孪生的难度之高，以及对计算等基础设施资源的需求极高。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long  Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
数字孪生是充分利用物理模型、传感器更新、运行历史等数据，集成多学科、多物理量、多尺度、多概率的仿真过程，在虚拟空间中完成映射，从而反映相对应的实体装备的全生命周期过程。早期被提出用于实现战斗机维护工作的数字化，后在工业制造和智慧城市等领域应用。随着移动网络新业务出现和网络规模持续扩大，网络运营和维护复杂度高，创新技术落地部署困难。因此，数字孪生被认为是6G网络的重要方向之一，为移动网络提供全生命周期的智慧运维和智能自治。
在网络管理系统中各个网络功能被定义为管理功能(managed funciton)或管理单元(managed element)，并对各个管理功能/单元(managed funciton/element)进行模型定义。基于网络资源模型(Network resource model，NRM)进行FCAPS(fault，configuration，accounting，performance，security，错误、配置、计帐、性能和安全)管理。
网络功能虚拟化(Network Function Virtulization，NFV)基于通用的硬件资源构建网络功能虚拟化基础设施，通过软硬分离的方式实现电信网络部署。因此基于NFV技术，可灵活地对硬件资源进行分配，为不同网络功能硬件资 源之间的共享或隔离提供了基础。基于5G核心网服务化架构，5G核心网功能同样可以根据业务场景需要实现某个网络功能的共享或某个网络功能的隔离。
数字孪生目前主要应用于工业制造领域和智慧城市，侧重于通过物理模型和传感器等获得数据，并进行数字域的镜像构建，为新产品设计和城市发展提供全生命周期更准确和高效的预先验证。而对于移动网络如何进行数字孪生，对应的网络架构和方案还在探索中。
现有网络网管系统的管理功能或管理单元并不包括用户设备(User Equipment，UE)，因此网管系统并未涉及UE级FCAPS管理。而数字孪生网络中UE级的信息和建模是非常重要的一部分，因此移动网络数据孪生方案需要解决UE级数据采集和/或建模方案。
移动网络现网部署通常按照网络峰值容量设计和部署，因此在非高负荷的时段，移动网络资源存在一定富余。由于非高负荷时移动网络资源富余，为减少无意义的功耗，通常会通过服务器节电或载波关断等技术降低网络功耗。同时，为保证电信级99.999％的可靠性要求，移动网络中关键设备在运行中均有备份。因此，数字孪生网络和物理网络可作为一个整体考虑，复用资源，从而提升效率。
本申请实施例提出了一种资源复用的移动网络数字孪生方案，引入了数字孪生管理功能(Digital Twin Management Function，DTMF)。DTMF负责接收移动网络数字孪生模板；基于移动网络数字孪生模板信息，与物理网络功能(包括核心网(Core Network，CN)、无线接入网(Radio Access Network，RAN)、UE和/或网管系统功能/服务)和/或基础设施管理功能交互获得现有物理网络部署情况、状态信息和/或基础设施状态；进而分析和决策支持该数字孪生网络的地理位置区域和/或用户和/或网络功能；负责对数字孪生网络功能进行数字孪生相关的配置(C)、错误(F)和安全(S)等管理，以及与物理网络功能交互数字孪生的信息。如果数字孪生涉及UE级数据采集和/或需 UE参与，那么DTMF需要触发和/或获得用户授权。当涉及UE级信息时，用户授权结果是DTMF分析和决策本次数字孪生网络的影响因素之一。如果需要，DTMF还可向需求方反馈其决策的数字孪生网络参数。
本申请实施例提供一种数字孪生方法，由数字孪生管理功能实体执行，如图1所示，包括：
步骤101：接收移动网络数字孪生模板；
步骤102：根据所述移动网络数字孪生模板的信息，与物理网络功能和/或基础设施管理功能交互获得物理网络部署情况、状态信息和/或基础设施状态；
步骤103：根据交互获得的信息确定支持数字孪生网络的地理位置区域和/或用户终端和/或网络功能。
在本申请实施例中，数字孪生管理功能，基于移动网络数字孪生模板，决策在何时和以何种方式复用现有网络的哪些资源形成数字孪生网络，一方面提高了现网资源利用率，另一方面降低了数字孪生网络的开销。
如图2所示，DTMF通过移动网络数字孪生模板获得数字孪生网络需求，根据移动网络数字孪生模板信息与网络管理服务和/或物理网络功能和/或网络功能虚拟化编排器(Network Functions Virtualization Orchestrator，NFVO)交互获得现网部署情况、网络状态信息、和/或UE授权信息、和/或计费信息、和/或网络功能虚拟化基础设施状态，从而决策支持该数字孪生网络服务的地理位置区域和/或UE、网络功能虚拟基础设施资源。基于决策对数字孪生网络功能进行配置，与物理网络功能交互数字孪生信息。本实施例的技术方案适用于5G或者6G系统。
一些实施例中，所述方法还包括：对数字孪生网络功能进行配置管理、错误管理和安全管理，配置管理的信息包括以下至少一项：
所述数字孪生网络功能和所述物理网络功能的协作策略；
所述数字孪生网络功能和所述物理网络功能的同步策略；
所述数字孪生网络功能的配置信息，包括数字孪生的核心网功能配置，数字孪生的无线接入网功能配置，和/或，数字孪生用户的终端配置，例如对数字孪生的核心网功能配置数字孪生用户的授权信息、上下文信息等；对数字孪生的无线接入网功能配置小区频段、功率、邻区信息等；对数字孪生用户终端配置用户配置文件标识符(subscriber profile Identity，subscriber profile ID)等以实现数字孪生服务的专用配置。
一些实施例中，若数字孪生涉及用户终端级数据采集和/或需用户终端参与，所述方法还包括：
触发和/或获得用户终端授权，授权的交互方式可以是短信、网上营业厅/应用程序(Application，APP)、物理营业厅面对面或上述方式的组合。DTMF考虑数字孪生移动网络生命周期特点，除数字孪生需使用的数据或服务外，数字孪生的UE授权过程中交互的信息包括以下至少一项：
数字孪生服务的时间信息，如果需要UE长期提供数字孪生服务，那么是授权生效到截止的时间区间；如果不需要UE长期提供数字孪生服务时，则需要向用户提供数字孪生服务的具体时间，可以是开始时间，和/或结束时间，和/或时间长度。例如开始时间3：00AM(GMT+8)，结束时间5：00AM(GMT+8)；
数字孪生服务的计费方式和价格，当涉及计费时，需要交互此信息。计费方式可以是流量计费或价格计费等，计费价格可以是按次一次性定价(如*G/M流量/次，*话费/次)，或基于时间的单价(如*G/M流量/15分钟，*话费/15分钟)等；
用户终端的数字孪生模式，可以是纯数字孪生模式，或者数字孪生和物理网络共存模式；
数字孪生所需的用户终端资源信息，例如多大内存、哪些用户注册信息、电池电量等。
如果数字孪生移动网络涉及计费，根据用户授权的结果，那么DTMF需 要与计费功能交互授权的UE信息(如UE标识)、计费方案和/或价格，所述方法还包括：
与计费功能交互授权的用户终端信息、计费方案和/或价格。
根据需求，DTMF向需求方反馈数字孪生网络参数，数字孪生网络参数是指基于移动网络数字孪生模板信息，DTMF最终决策的可实例化的数字孪生网络的具体参数信息。该参数信息不涉及网络和用户敏感信息，所述数字孪生网络参数包括以下至少一项：
场景参数，例如室内楼宇场景，可提供楼层数、建筑物材质等；
网络拓扑参数，所述网络拓扑参数包括以下至少一项：核心网功能、无线接入网功能和传输网的拓扑关系；蜂窝网络小区拓扑；邻区关系配置信息；波束参数配置信息；
用户终端参数，所述用户终端参数包括以下至少一项：用户终端的数量；用户终端的分布；用户终端的移动性特征分布；用户终端的型号；用户终端在数字孪生网络中的终端能力。例如此次数字孪生网络实例中UE总数，UE分布(如和各小区归属关系)，UE的终端型号或终端能力信息等。终端的能力信息是指UE在数字孪生网络中的终端能力，可与物理网络中的终端能力不同，该终端能力与上述数字孪生网络授权信息和UE数字孪生模式相关。
本实施例的应用场景是运营商像提供流量和话音一样提供数字孪生服务，所以一些行业客户可以向运营商定制数字孪生服务，可以将数字孪生的需求以移动网络数字孪生模板的方式提供给运营商的数字孪生管理功能，然后数字孪生管理功能在决策建立满足需求的数字孪生实例后可以将上述数字孪生实例的网络参数反馈给需求方。
移动网络数字孪生模板是对数字孪生移动网络的描述，包括以下至少一项：
数字孪生目标，可以是方案验证或数据采集等；
数字孪生类型，可以是静态或动态等，静态是指数字孪生网络模型不变， 例如相关小区、相关UE、空口带宽和覆盖范围等不变，改变数字孪生目标问题中相关参数形成多个快照的结果达到数字孪生目标；动态是指在连续时间上数字孪生，例如以某个时间(如某年某月某时某分某秒形式)为起点，到某个时间为止；或者以事件驱动方式，例如终端进行切换，那么从终端发起切换开始进行一段时间上的数字孪生；
数字孪生网络功能集及各功能的数字孪生模式，数字孪生功能集指示数字孪生网络由哪些数字孪生网络功能组成，如核心网、传输网、无线接入网、UE等。对于所包含的数字孪生网络功能指示其数字孪生模式，可以是纯数字孪生模式、数字孪生和物理网络共存模式；
场景，可以是室内/室外，也可以是高校、居民区、商场、办公楼等，也可以通过面积等维度对场景进行描述；
孪生体和物理实体协作策略，当孪生体和物理实体复用资源时有效，可以是物理实体优先或孪生体优先，如果孪生体和物理实体内部均支持服务质量分级，也可通过服务质量分级来细化定义二者之间的协作策略；
孪生体和物理实体同步策略，可以是指定时间一次性同步或周期性同步等；
计费策略，数字孪生涉及的计费最多包括如下两个部分，当不涉及网络数字孪生客户和移动用户的UE时，可以不提供这一信息：针对向运营商提出网络数字孪生需求的客户的计费，可以是按数字孪生网络规格(网络功能和/或流量)计费、包月等方式；针对参与数字孪生网络的用户终端的移动用户的计费，可以是按流量计费或按支持数字孪生次数等方式。特别需要说明的是，因为在数字孪生情况下的服务提供方和消费方与正常情况下相反，即用户属于服务提供方，因此这里的计费的作用是对用户支付的费用。考虑与现有计费系统融合，按流量计费时，可按照一定折算方法，在用户套餐流量基础上额外加入支持数字孪生获得的流量；按次数计费时，可按照定价方法，在用户帐户中以话费方式支付；
移动用户要求，包括移动用户数量，用户移动性要求(例如近似静止、步行、车速等，或者不同移动用户占比)，用户的终端型号要求，用户消费特征(如月话费小于100元)等。如果数字孪生网络不涉及移动用户时，则无需包含此信息；
数字孪生功能软件包和对应的描述文件，当数字孪生网络包括数字孪生客户特有的功能时，需要通过预先约定方式提供该特有功能的软件包和对应的描述文件。描述文件包括部署资源需求，与其他功能的连接关系等。例如，包含定制资源分配算法的中央单元-控制平面(Central Unit-Control Plane，CU-CP)功能，那么通过模板提供CU-CP软件包，并描述CU-CP通过下一代(Next Generation，NG)接口x版本与认证管理功能(Authentication Management Function，AMF)连接，通过E1接口y版本与CU-UP连接，通过F1接口z版本与分布单元(Distribute Unit，DU)连接。DTMF将根据描述文件信息将所需功能的软件包进行实例化，部署到合适位置和完成相关接口的连接，并进行F、C和S管理。
本实施例中，DTMF根据移动网络数字孪生模板信息，与物理网络功能和/或基础设施管理功能交互。具体可与网管系统功能/服务(如MDAS，management data analytics service)和/或物理核心网功能(如NWDAF，Network Data Analytics Function)和/或基础设施管理功能(如NFVO，网络功能虚拟化编排器)交互获得现有物理网络部署情况、状态信息和/或网络功能虚拟化基础设施状态，分析和决策支持该数字孪生网络的地理位置区域和/或用户和/或网络功能。DTMF也可基于与网络管理系统和/或网络功能交互的历史网络状态信息，通过人工智能(Artificial Intelligence，AI)等方法预测在何时、以何种方式可以复用现有网络的哪些资源/功能支持该数字孪生网络，进而确定数字孪生网络的地理位置区域和/或用户、网络功能虚拟基础设施资源。
DTMF和网络管理系统功能协同完成数字孪生网络部署后，根据移动网络数字孪生模板信息对数字孪生网络功能和/或物理网络功能进行配置。从而 数字孪生网络功能和物理网络功能进行同步和协同，完成数字孪生。例如数字孪生网络功能与物理网络功能复用基站硬件资源和UE硬件资源时，DTMF配置复用的具体参数，包括数字孪生网络功能和物理网络功能所对应的时间，及各自的网络配置信息等。
通过移动网络数字孪生模板定义，DTMF可支持与模板适配的动态用户授权、计费策略和数字孪生网络实例功能，达到复用现有网络部署资源和提升数字孪生精确度的效果。
