下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
为了方便理解，以下对本公开实施例涉及的一些内容进行说明：
1、数字孪生
数字孪生是一种数字化理念和技术手段，它以数据与模型的集成融合为基础与核心，通过在数字空间实时构建物理对象的精准数字化映射，基于数据整合与分析预测来模拟、验证、预测、控制物理实体全生命周期过程，最终形成智能决策的优化闭环。其中，面向的物理对象包括实物、行为、过程，构建孪生体涉及到的数据包括实时传感数据和运行历史数据，集成的模型涵盖物理模型、机理模型和流程模型等。
数字孪生的概念始于航天军工领域，经历了“技术探索、概念提出、应用萌芽、行业渗透”四个发展阶段。数字孪生技术最早在1969年被美国国家航空航天局(National Aeronautics and Space Administration，NASA)应用于阿波罗计划中，用于构建航天飞行器的孪生体，反映航天器在轨工作状态，辅助紧急事件的处置。2003年，数字孪生概念正式被密歇根大学的Grieves教授提出，并强调全生命周期交互映射的特征。经历了几年的概念演进发展后，自2010年开始，数字孪生技术在各行业呈现应用价值，美国军方基于数字孪生实现F35战机的数字伴飞，降低战机维护成本和使用风险；通用电器为客机航空发动机建立孪生模型，实现实时监控和预测性维护；欧洲工控巨头西门子、达索、ABB在工业装备企业中推广数字孪生技术，进一步促进了技术向工业领域的推广。近年来，数字孪生技术在工业、城市管理领域持续渗透，并向交通、健康医疗等垂直行业拓展，实现机理描述、异常诊断、风险预测、决策辅助等应用价值，有望在未来成为经济社会产业数字化转型的通用技术。
数字孪生体构建了网络的数字空间，实现了虚实映射。随着数字孪生技术的发展以及整个网络运维越来越复杂，并考虑到网络故障的高代价以及昂贵的试验成本，需要在传统物理网络进行外部抽象映射，建立一个新的发展体系，构建全新的数字孪生体，通过虚实结合的闭环控制，来改变现有网络规、建、维、优的既定规则，有效保障网络运维，实时优化网络，实现未来网络自治。
2、数据面
6G架构的三层四体五面，五面中的一面为数据面。数据面是6G网络架构中新增的一个平面，其目的是实现庞大用户数据的高效安全迭代、网络状态的可靠迁移、以及通过可信的方式引入数据服务。该平面将构建高效、统一的数据管理功能，支持精细化的数据采集、高效的数据传输、灵活的数据存储、分布式数据协同，兼顾考虑数据的可靠性、数据隐私和安全，实现对数据全生命周期的闭环管理，同时将数据作为一种服务产品，构建基于数据提供者和消费者的业务逻辑，提供多样化的数据增值服务。主要具有数据融合、数据连续性、数据服务等能力。所以，数据面收集并存储来自移动用户 和智能网络元件的全部数据，这些数据可以由人工智能平面出于特定目的来订阅。
本公开实施例提供了一种信息交互方法及装置。其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1所示，为本公开实施例提供的一种信息交互方法，包括：
步骤101，第一设备获取物理网络体的第一信息，所述第一信息包括以下至少一项：控制面信息，用户面信息，终端相关信息；
步骤102，所述第一设备向数字孪生网络体的网元发送所述第一信息和/或所述第一信息对应的指令；
其中，所述第一设备包括以下至少之一：
管理所述物理网络体的第一管理系统和管理所述数字孪生网络体的第二管理系统，其中，所述第一管理系统和所述第二管理系统之间设置有第一接口；
信息交互设备，其中，所述信息交互设备与所述数字孪生网络体之间设置有第二接口，所述信息交互设备与所述物理网络体之间设置有第三接口；
所述数字孪生网络体的第一网元和第二网元，其中，所述第一网元具备对所述物理网络体的网元进行网元服务发现的能力，所述第二网元具备对所述物理网络体的网元进行事件暴露服务订阅的能力；
所述物理网络体的第三网元和所述数字孪生网络体的第四网元，其中，所述第三网元具备向所述物理网络体的网元调用服务发现的能力以及订阅事件暴露服务的能力，且所述第三网元和所述第四网元之间支持信息交互。
这样，如上所述的第一设备建立起物理网络体和数字孪生网络体之间的信息交换桥梁，实现物理网络体和数字孪生网络体之间的信息交互。
可选地，所述第一设备获取物理网络体的第一信息，包括：
所述第一设备向第一目标网元发送第一请求，并接收所述第一目标网元基于所述第一请求反馈的第一响应，其中，所述第一响应包括所述第一信息；或者，
所述第一设备接收第一目标网元发送的第二请求，其中，所述第二请求 包括所述第一信息；
其中，所述第一目标网元为所述物理网络体的网元。
也就是说，第一设备能够向所述第一目标网元发送第一请求，来请求获取所述第一信息，而所述第一目标网元在接收所述第一请求后，反馈包括所述第一信息的第一响应；或者，所述第一目标网元主动发送包括所述第一信息的第二请求，第一设备通过接收所述第二请求获取到所述第一信息。
作为一种实施方式，所述第一设备接收所述第二请求后，反馈第二响应。该第二响应用于指示是否成功接收所述第二请求。
当然，该实施例中，第一设备向数字孪生网络体的网元发送所述第一信息和/或所述第一信息对应的指令，也可以采用请求-响应机制。
需要说明的是，本公开实施例中，所述第一信息对应的指令是基于所述第一信息所指示的具体内容确定的。例如，第一信息指示会话管理功能网元的状态(上线或下线)，则所述第一信息对应的指令可以为注册指令或去注册指令。此外，所述第一信息对应的指令还可以是更新用户面信息的动作指令，如链路断开、端口启动/关闭等。
可选地，所述第一响应或所述第二请求用于发送所述第一目标网元存储的所有网元对应的所述第一信息。
故，所述第一目标网元可以通过第一响应或第二请求，在一次传输中将其存储的所有网元对应的所述第一信息告知第一设备，提高传输效率，减少信令开销。此时，第一目标网元可以是网络存储功能网元、会话管理功能网元，通过对网络存储功能网元、会话管理功能网元在存储多个网元对应的第一信息的情况下，将其存储的所有网元对应的第一信息告知第一设备。
作为一种实施方式，第一请求用于请求第一目标网元反馈存储的所有网元对应的所述第一信息。
当然，若第一目标网元(如用户面功能网元)仅能够存储自身对应的第一信息，用户面功能网元发送的也仅能是自身对应的第一信息，不包括其它网元对应的第一信息。
可选地，所述第一目标网元为会话管理功能网元，且所述第一信息包括用户面信息的情况下，所述会话管理功能网元具备获取用户面拓扑信息的能 力。
即，会话管理功能网元能够获取用户面拓扑信息，当会话管理功能网元通过第一响应或第二请求发送用户面信息的情况下，用户面信息包括用户面拓扑信息，如此，数字孪生网络体的网元获得的用户面信息也能够包括用户面拓扑信息，以实现数字孪生网络体的用户面功能网元的建立、更新和维护。
该实施例中，对于第一设备包括所述第一管理系统和所述第二管理系统的情况，所实现的是物理网络本体与数字孪生网络体通过各自的管理系统完成信息交互。其中，第一管理系统作为管理物理网络体的管理系统，向第一目标网元发送第一请求，从而通过反馈的第一响应获取到第一信息；或者，直接接收第一目标网元发送的第二请求，获取第一目标网元主动上报的第一信息。之后，第一管理系统由与所述第二管理系统之间设置的第一接口，将第一信息发送给第二管理系统。所以，可选地，所述第一设备包括所述第一管理系统和所述第二管理系统的情况下，
所述第一设备向数字孪生网络体的网元发送所述第一信息，包括：
所述第二管理系统在接收到所述第一管理系统通过所述第一接口发送的所述第一信息后，向所述数字孪生网络体的网元发送所述第一信息和/或所述第一信息对应的指令。

可选地，所述第一请求为查询请求。
即，所述第一设备包括所述第一管理系统和所述第二管理系统，或者所述第一设备包括所述信息交互设备时，所述第一设备发送的第一请求为查询请求。
该实施例中，对于第一设备包括所述第一网元和所述第二网元的情况，所实现的是物理网络本体与数字孪生网络体之间通过数字孪生网络体的网元进行信息交互。其中，所述第一网元和所述第二网元进行了功能增强，使得第一网元和第二网元能够获取到第一信息。所以，可选地，所述第一设备包括所述第一网元和所述第二网元的情况下，所述第一请求包括网元服务发现请求和/或事件暴露服务订阅请求；
所述第一设备向第一目标网元发送第一请求，并接收所述第一目标网元基于所述第一请求反馈的第一响应，包括以下至少一项：
所述第一网元向第五网元发送网元服务发现请求，并接收所述第五网元反馈的网元服务发现响应，所述网元服务发现响应携带所述控制面信息；
所述第二网元向第六网元发送事件暴露服务订阅请求，并接收所述第六网元反馈的事件暴露服务订阅响应，所述事件暴露服务订阅响应携带所述用户面信息；
其中，所述第五网元和所述第六网元属于所述第一目标网元，且所述第六网元允许订阅事件暴露服务。
作为一种实施方式，所述第一网元可以是网络存储功能网元，所述第二网元可以是会话管理功能网元。其中，数字孪生网络体的会话管理功能网元 除通过向第六网元订阅事件暴露服务来获得用户面信息之外，还能够直接向物理网络体的网元如用户面网元直接查询用户面信息。
另由于所述第一网元和所述第二网元均为数字孪生网络体的网元，在获取第一信息，将第一信息或第一信息对应的指令发送给数字孪生网络体的其它网元的过程，可采用请求-响应机制，在此不再赘述。
可选地，所述第一网元为网络存储功能网元的情况下，所述网络存储功能网元能够向所述数字孪生网络体的第二目标网元主动下发信息和/或指令。
以第五网元为物理网络体的网络存储功能网元为例，数字孪生网络体的网络存储功能网元作为第一网元，从物理网络本体的网络存储功能网元通过服务化操作获得控制面信息(如网络功能网元的上下线状态信息)时，能够将该控制面信息和/或该控制面信息对应的指令发送给对应的第二目标网元，即数字孪生网络体的网络功能网元，从而使该网络功能进行注册或去注册，完成控制面之间的信息交互和更新。此时，增加了数字孪生网络体的网络存储功能网元向数字孪生网络体的网络功能网元主动发送注册/去注册指令(也可是请求)的能力。当然，为适用不同场景，数字孪生网络体的网络存储功能网元增加的能力不限于主动发送注册/去注册指令，还能够主动发送其它信息和/或指令。如此，网络存储功能网元通过能力增强，不再仅能够被动获取信息和/或指令，还能够向所述数字孪生网络体的第二目标网元主动下发信息和/或指令，建立起物理网络体和数字孪生网络体之间的信息交换桥梁。
应该知道的是，若数字孪生网络体的网络存储功能网元向未注册的网元发送注册请求时，可能存在网络存储功能网元找不到这个未注册网元的情况，即指令发送不到对应的网元。此种情况下，可由网络存储功能网元把相关指令发送给其它网元或实体(如：网络功能虚拟化管理和编排器(Management and Network Orchestration，MANO)等)，进而实现相关网元的注册。
数字孪生网络体的会话管理功能网元作为第二网元，可参照接入及移动性管理功能网元的事件暴露服务，增加数字孪生网络体的会话管理功能网元对物理网络体的网元进行事件暴露服务订阅的能力，数字孪生网络体的会话管理功能网元可订阅物理网络体会话管理功能网元的事件暴露服务，进而完成用户面的信息交互；或数字孪生网络体的会话管理功能网元直接向用户面 网元查询用户面信息。
例如，第一网元(如V-网络存储功能网元)从第五网元(如网络存储功能网元)获取控制面信息；第二网元(如V-会话管理功能网元)从第六网元(如会话管理功能网元)获取用户面信息，如图12所示的步骤1-10：
步骤1：V-网络存储功能网元向第五网元(如物理网络体的网络存储功能网元)发送第一请求，如网元服务发现请求。具体地，网元服务发现请求能够发现的网络存储功能网元中的控制面信息(即控制面网元的信息)，如网元状态、网元标识等信息。
步骤2：网络存储功能网元向V-网络存储功能网元发送第一响应，如网元服务发现响应。具体地，第一响应主要携带的信息为网元的状态、网元的标识等信息。
步骤3：V-会话管理功能网元向第六网元(如物理网络体的会话管理功能网元)发送第一请求，如事件暴露服务订阅请求，简称事件暴露订阅请求。具体的，事件暴露订阅请求主要订阅物理网络体的会话管理功能网元的用户面信息，如转发设备标识、链路信息、端口号、端口状态等信息。
步骤4：当物理网络体内的会话管理功能网元收集到用户面信息及信息更新时，向V-会话管理功能网元发送第一响应，如事件暴露服务订阅响应，简称事件暴露订阅响应。具体地，第一响应主要携带的有转发设备标识、链路信息、端口号、端口状态等信息。
步骤5：V-会话管理功能网元把最新的用户面信息通过用户面信息更新请求更新到V-用户面网元，并对V-用户面网元下发针对最新用户面信息的动作指令(如：链路断开、端口启动/关闭等)。
步骤6：V-用户面网元收到用户面信息更新请求后，向V-会话管理功能网元发送用户面信息更新响应。
步骤7：V-用户面网元根据最新用户面信息和动作指令做出调整更新，如用户面信息更新。
步骤8：V-网络存储功能网元根据服务发现到的控制面网元信息，通过控制面信息更新请求下发指令到对应的V-网络功能网元，比如查询到会话管理功能网元的状态为下线，则V-网络存储功能网元向本体内的会话管理功能
网元发送去注册指令。
步骤9：数字孪生网络体内的V-网络功能网元收到V-网络存储功能网元发送的控制面信息更新请求后，向V-网络存储功能网元发送更新响应。
步骤10：数字孪生网络体内的V-网络功能网元根据收到的指令做出状态等信息的更新，如注册或去注册。
又或者，如图13所示的步骤1-10，相较于图12所示步骤1-10，把物理网络体的会话管理功能网元换成了用户面网元，步骤3-4换成了用户面信息查询请求和响应，由V-会话管理功能直接向用户面网元查询用户面信息，但查询的用户面信息无差别，其它步骤无变化。
需要说明的是，在图12和图13中，步骤1-2和3-4没有先后之分，可以先执行步骤1-2和后执行步骤3-4，也可以先执行步骤3-4和后执行步骤1-2，也可以同时执行。类似的，步骤5-6和步骤8-9也没有先后之分，在此不再赘述。
该实施例中，对于第一设备包括所述第三网元和所述第四网元的情况，所实现的是物理网络体与数字孪生网络体之间通过各自的网元进行信息交互。所以，可选地，所述第一设备包括所述第三网元和所述第四网元的情况下，所述第一请求包括网元服务发现请求和/或事件暴露服务订阅请求；

其中，所述第二目标网元为所述数字孪生网络体的网元。
这里，第四网元向第二目标网元发送所述第一信息和/或所述第一信息对应的指令可采用请求-响应机制，在此不再赘述。
这里，所述第三网元可以为所述物理网络体的常规网元，通过增加所述第三网元向所述物理网络体的网元调用服务发现的能力以及订阅事件暴露服务的能力，以及与所述第四网元交互信息的能力。
或者，所述第三网元为所述物理网络体新增加的网元，具备向所述物理网络体的网元调用服务发现的能力以及订阅事件暴露服务的能力，以及与所述第四网元交互信息的能力。
同样的，所述第四网元可以为所述数字孪生网络体的常规网元或者所述数字孪生网络体新增加的网元。
作为一种实施方式，第三网元、第四网元是各自网络体在原有控制面网元的基础上添加一个新的数据存储功能网元，用来存储终端、无线、核心网等的数据信息。
例如，物理网络体的数据存储功能网元作为第三网元，调用第七网元如网络存储功能网元服务发现功能，进而发现网络存储功能中的网元信息；同时数据存储功能网元可向会话管理功能网元调用事件暴露功能，进而获取用户面的信息，如图14所示的步骤1-14：
步骤1：物理网络体的数据存储功能网元向第七网元(如网络存储功能网元)发送第一请求，如网元服务发现请求。具体地，网元服务发现请求主要发现网络存储功能网元的控制面信息(即控制面网元的信息)为网元状态、网元标识等信息。
步骤2：网络存储功能网元向数据存储功能网元发送第一响应，如网元服务发现响应。具体地，第一响应主要携带的信息为网元的状态、网元的标识等信息。
步骤3：数据存储功能网元向第八网元(如会话管理功能网元)发送第一请求，如事件暴露服务订阅请求，简称事件暴露订阅请求。具体的，事件暴露订阅请求订阅物理网络体内会话管理功能网元中用户面的信息，转发设 备标识、链路信息、端口号、端口状态等信息，该事件暴露订阅请求可携带转发设备标识、链路信息、端口号、端口状态等信息表明查询目标。
步骤4：会话管理功能网元向数据存储功能网元发送第一响应，如事件暴露服务订阅响应，简称事件暴露订阅响应。具体地，第一响应主要携带的有转发设备标识、链路信息、端口号、端口状态等信息。
步骤5：数据存储功能网元把收集到的控制面信息和用户面信息通过信息更新请求发送到V-数据存储功能网元。
步骤6：V-数据存储功能网元收到信息更新请求后，向数据存储功能网元发送信息更新响应。
步骤7：V-数据存储功能网元把查询到的用户面信息通过用户面信息更新请求更新到V-会话管理功能网元，携带的主要有转发设备标识、链路信息、端口号、端口状态等信息。
步骤8：数字孪生网络体内的V-会话管理功能网元收到用户面信息更新请求后，对其做出更新响应。
步骤9：V-会话管理功能网元向V-用户面网元发送信息更新请求，把最新的用户面信息更新到本体内的V-用户面网元；并下发针对最新用户面信息的动作指令(如：链路断开、端口启动/关闭等)。
步骤10：V-用户面网元收到信息更新请求后，向V-会话管理功能网元发送信息更新响应。
步骤11：V-用户面网元根据最新用户面信息和动作指令做出调整更新，如用户面信息更新。
步骤12：V-数据存储功能网元根据查询到的控制面网元信息，通过控制面信息更新请求下发指令到对应的V-网络功能网元，比如查询到会话管理功能网元的状态为下线，则V-数据存储功能网元向本体内的会话管理功能网元发送去注册指令。
步骤13：数字孪生网络体内的V-网络功能网元收到V-数据存储功能网元发送的控制面信息更新请求后，向V-数据存储功能网元发送更新响应。
步骤14：数字孪生网络体内的V-网络功能网元根据收到的指令做出状态等信息的更新，如注册或去注册。
需要说明的是，在图14中，步骤1-2和3-4没有先后之分，可以先执行步骤1-2和后执行步骤3-4，也可以先执行步骤3-4和后执行步骤1-2，也可以同时执行。类似的，步骤7-8和步骤12-13也没有先后之分，在此不再赘述。
另外，上述示例中主要说明了物理网络体和数字孪生网络体中控制面网元和用户面网元的相关信息交互；但物理网络体和数字孪生网络体还能够进行终端相关信息的交互。以第一设备为第三管理系统或数据存储设备为例，第三管理系统或数据存储设备也可通过向接入及移动性管理功能网元查询终端的上下文信息和会话管理功能网元查询终端的相关会话信息来获取终端相关信息，进而把此信息更新到数字孪生网络体的V-接入及移动性管理功能网元和V-会话管理功能网元，最后V-接入及移动性管理功能网元和V-会话管理功能网元再通过相关模块实现数字孪生网络体中终端的去注册/注册，以及会话建立/会话释放。如图15所示的步骤1-8：
步骤1：第三管理系统或数据存储设备向接入及移动性管理功能网元发送终端(UE)上下文信息查询请求，向其查询终端上下文消息为终端的状态、终端标识、终端数量等信息。
步骤2：接入及移动性管理功能网元收到终端上下文消息后，接入及移动性管理功能网元向第三管理系统或数据存储设备发送UE上下文信息查询响应。

步骤7：第三管理系统或数据存储设备把查询到的终端上下文信息通过UE上下文信息更新请求更新到V-接入及移动性管理功能网元，携带的主要 有终端的状态、终端标识、终端数量等消息。
步骤8：数字孪生网络体内的V-接入及移动性管理功能网元收到UE上下文信息更新请求后，对其做出更新响应。
需要说明的是，在图15中，步骤1-2和3-4没有先后之分，可以先执行步骤1-2和后执行步骤3-4，也可以先执行步骤3-4和后执行步骤1-2，也可以同时执行。类似的，步骤5-6和步骤7-8也没有先后之分，在此不再赘述。
此外，在图2-图15中，请求的接收端返回响应的步骤和继续执行的步骤可以没有先后之分。以图2为例，步骤8和步骤9的执行顺序可以是先执行步骤8和后执行步骤9，也可以先执行步骤9和后执行步骤8，还可以两者同时执行。
此外，可选地，所述第一信息为所述物理网络体发生变化时的信息。
