[0002] The current proposed digital twin network construction method generally builds a complete digital twin network, which includes collecting data from the physical network and storing the data, then modeling network objects and topology based on the collected data, and finally generating a complete network digital twin based on the model.

Among them, both the digital twin orchestration function and the digital twin control function can interact with the model library. The digital twin orchestration function can obtain the relevant information of the existing digital twin-related twin models through the model library, thereby generating the orchestration results; the digital twin control function can obtain the relevant twin models from the model library based on the orchestration results, so as to perform the relevant control of the subsequent digital twin network instance.

[0098] The digital twin network instance is the execution entity of the digital twin network, which may include the digital twin network function instance and the data acquisition and processing instance. The data acquisition and processing instance is used to collect data and transmit the collected data; the digital twin network function instance is mainly used to realize the corresponding network function. The digital twin network instances cooperate with each other to jointly realize the required digital twin network, that is, to realize the virtual network mirroring oriented to business needs.

[0099] The embodiment of the present invention proposes orchestration functions and control functions for the orchestration and control of digital twin network instances, supports dynamic generation of digital twin network instances that meet business needs based on consumer needs, runs digital twin network instances to provide digital twin network services, and thus provides digital twin network services for specific needs. It solves the data transmission overhead and latency problems brought by centralized digital twin networks in actual applications through distributed deployment of digital twin network instances. In addition, the technical solution of the embodiment of the present invention improves resource utilization while meeting business needs.

[0100] Figure 5 Schematic diagram of the interactive process of the method for constructing a digital twin network according to an embodiment of the present invention; Figure 5 As shown, the method includes:

[0101] Step 301: The digital twin consumer sends a digital twin network construction request to the orchestration function.

[0102] Here, the digital twin network construction request includes relevant information of the digital twin network. The relevant information of the digital twin network may include relevant information of the constructed digital twin network, for example, at least one of the following information: the target network identifier, target time period, target service identifier (ID), target service model and service volume of the digital twin, etc. Among them, the target network identifier is to determine the target network to be twinned, which can be an end-to-end network or a part of an end-to-end network; the target time period refers to a certain time period in the past, present and future of the target network to be digitally twinned; the target service ID is to identify the service or service combination running on the target network to be digitally twinned; the target service model and service volume refer to the traffic model and service volume of the service running on the target network of the digital twin. For example, the target service model can be reflected by the traffic model identifier of the service, and the service volume can be reflected by the specific value, value threshold or value range of the service volume. Optionally, the relevant information of the constructed digital twin network, for example, represents or indicates: building a digital twin network for XR service assurance. On the other hand, the relevant information of the digital twin network may also include relevant information of nodes or objects that have an interactive relationship with the constructed digital twin network; wherein the node or object that has an interactive relationship with the digital twin network refers to, for example, the consumer that issues the first request, or may refer to the user node or object of the digital twin network, and the source data node of the digital twin network, etc. Among them, the relevant information of the node or object that has an interactive relationship with the constructed digital twin network may refer to the location information (such as geographic location information) of the node or object that has an interactive relationship with the digital twin network.

[0103] Step 302: The orchestration function digital twin network construction request, the twin model of the existing digital twin network and the network networking information are analyzed to generate the orchestration result of the digital twin network instance.

[0104] Here, the orchestration function performs a comprehensive analysis based on the construction requirements of the digital twin network, the existing digital twin network related models and the networking information of the physical network, and generates the orchestration results of the digital twin network instance. Among them, the orchestration function can specifically determine the digital twin network instance required for the digital twin network according to the relevant information of the digital twin network in the construction requirements, as well as the connection relationship and interaction relationship of each digital twin network instance, and determine the deployment location of the digital twin network instance determined according to the network networking information. In other optional embodiments, after the orchestration function determines the digital twin network instance required for the digital twin network, it can also determine the deployment location according to the network networking information and the relevant information (such as location information) of the nodes or objects that have an interactive relationship with the constructed digital twin network, for example, the relevant digital twin network instance can be deployed in a position close to the nodes or objects that have an interactive relationship with the digital twin network, etc. Among them, the nodes that have an interactive relationship with the digital twin network, such as the source data nodes of the digital twin network, the consumer nodes of the digital twin network, etc.

[0105] Among them, the orchestration result may include: at least one digital twin network function instance, at least one data acquisition and processing instance, and at least one connection relationship and interaction relationship between digital twin network function instances, between data acquisition and processing instances, and between digital twin network function instances and data acquisition and processing instances. In other optional embodiments, the orchestration result may also include information such as the deployment location of each digital twin network instance. The digital twin network function instance, for example, is an AMF registration processing instance, an SMF session creation processing instance, a UPF flow processing instance, or a combination instance of multiple network functions, etc., and for example, a twin instance of a simulated network business flow model, a twin instance of a simulated terminal behavior model, and so on.

[0106] For example, taking the construction of a core network digital twin network for XR service assurance as an example, data collection and processing examples may include:

[0107] 1. Air interface service traffic collection instance, used to generate air interface service traffic consistent with the current network XR service; this instance can be deployed near the RAN side; 2. RAN load information collection and processing instance, used to generate a RAN background environment consistent with the current RAN performance status; this instance is deployed close to the RAN side node; 3. Core network load information collection and processing instance, used to generate a core network background environment consistent with the current network performance status; this instance can be deployed near the core network function node; 4. Core network service traffic collection and processing instance, used to generate core network service traffic consistent with the current network XR service; this instance is deployed near the UPF position.

[0108] Examples of digital twin network functions may include:

[0109] 5. RAN background environment instance generated based on collected RAN load information; 6. Air interface service flow instance constructed based on input of air interface service flow collection instance and service flow mapping model; 7. RAN scheduling processing behavior instance constructed based on air interface resource scheduling and forwarding model; 8. Wireless parameter adjustment instance constructed based on wireless parameter adjustment model; 9. Air interface service evaluation instance constructed based on air interface service evaluation model; 10.

Core network service evaluation instance constructed based on core network service evaluation model; 14. Core network parameter adjustment instance constructed based on core network parameter adjustment model. Examples of connections and interactions between instances are as follows: Figure 2 shown.

[0110] Step 303: The orchestration function sends the orchestration result to the control function. Based on the orchestration result, the control function can deploy, configure, start and manage the digital twin network function instance and data acquisition and processing instance throughout the life cycle.

[0111] Step 304: The control function obtains the twin model from the model library based on the orchestration result.

[0112] Here, the control function can obtain the required twin model from the model library, or it can obtain the required twin model through the online learning model in the running digital twin instance.

[0113] Step 305: Control function deployment and configuration of digital twin network function instances.

[0114] Here, the control function can be based on the orchestration results and data transmission costs and other factors, and the digital twin network function instance can be deployed close to the twin object, or it can be deployed in a centralized or hierarchical manner at a suitable location. After determining the deployment location, the twin model corresponding to the acquired digital twin network function instance is deployed through signaling or messages, and the association information between the digital twin network function instances, the operating environment and other information are configured.

[0115] Step 306: Control function deployment and data collection processing instance.

[0116] Here, the control function can determine the deployment location of the data acquisition and processing instance according to the orchestration result. Exemplarily, the data acquisition and processing instance is usually deployed near the data source. After determining the deployment location, the twin model corresponding to the acquired data acquisition and processing instance is deployed through signaling or messages, and the relevant information of the configuration data acquisition and processing instance and the association information between the configuration data acquisition and processing instance and the digital twin network function instance are configured. Among them, the relevant information of the configuration data acquisition and processing instance, for example, the relevant attributes of the configuration data acquisition and processing instance, including the collection scope, content, collection frequency, reporting frequency, output object, etc.

[0117] Optionally, when the existing data acquisition and processing instance can meet the data acquisition requirements, the control function can be updated based on the configuration of the existing data acquisition and processing instance, that is, a message or instruction is sent to the existing data acquisition and processing instance, and the message or instruction includes updated configuration information to meet the needs of the digital twin instance.

[0118] Step 307: The control function starts each digital twin network instance.

[0119] After the configuration and deployment preparations are completed, the control function starts all corresponding digital twin function instances.

[0120] Step 308: The control function monitors the status of each digital twin network instance.

[0121] Here, the control function can exchange information with each digital twin network instance. For example, the digital twin network instance can report information according to a specified strategy (such as periodicity, or reporting when an abnormality is detected). The control function receives the information reported by the digital twin network instance, thereby determining the status information of the digital twin network instance, and monitors the status of the digital twin network instance based on the status information, and performs timely processing and optimization when an abnormality is found.

[0122] Step 309: The digital twin consumer sends a digital twin network deletion request to the orchestration function, and the orchestration function sends the digital twin network deletion request to the control function.

[0123] Step 310: The control function sends instructions to each digital twin network instance to instruct it to stop running the digital twin network instance and recycle the resources of the digital twin network instance.
