[0001] The present application relates to the field of communication networks, and specifically to a network management service architecture, service method and storage medium for implementing digital twin services. Background Art

[0002] Digital Twins (DTs) are a technology that is gaining increasing attention in relation to system automation. A digital twin object is a virtual replica of a real-world system—a “physical” system—on which operations can be performed.

[0003] In the field of telecommunications standards research, the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) has defined a digital twin network reference architecture and related requirements that can be used for physical network simulation. However, there is currently no solution for how to build a network digital twin instance consisting of available components, topologies, and capabilities as a flexible virtual mirror of the physical network.

[0004] In the communications industry, digital twin-based technologies are used for data collection and element model creation. Fixed network digital twin platforms can be designed to meet digital twin applications, such as simulation. However, these platforms have fixed network elements, topologies, and functions, making them difficult to orchestrate and manage, making them difficult to adapt to 3rd Generation Partnership Project (3GPP) network management technologies.

[0005] Based on the above problems, how the 3GPP network management system can apply digital twin services so that digital twin services can better support network operation and maintenance is an urgent issue to be solved.

DETAILED DESCRIPTION

[0028] In order to make the application purpose, technical solutions and beneficial effects of this application clearer, the embodiments of this application are described below in conjunction with the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0029] Digital Twin Network (DTN) is a network system that creates virtual twins of physical network entities in a digital way and can interact with physical network entities in real time. Digital Twin Network can be designed as follows: Figure 1 The architecture shown, Figure 1 This is a schematic diagram of the "three-layer, three-domain, dual closed-loop" architecture of the digital twin network: the three layers refer to the physical network layer, twin network layer, and network application layer that constitute the digital twin network system; the three domains refer to the twin network layer data domain, model domain, and management domain, which correspond to the three subsystems of data sharing warehouse, service mapping model, and network twin management respectively; "dual closed loop" refers to the "inner closed loop" simulation and optimization based on the service mapping model within the twin network layer, and the "outer closed loop" based on the three-layer architecture for control, feedback, and optimization of network applications.

[0030] The following three types of interfaces are required to build a DTN system:

[0031] (1) Twin Southbound Interface: This includes the data acquisition interface and control delivery interface between the twin network layer and the physical network layer. The data acquisition interface is responsible for completing data acquisition in the twin network layer data sharing warehouse, and the control delivery interface is responsible for delivering control instructions after service mapping model simulation verification to the network elements of the physical network layer.

[0032] (2) Twin northbound interface: This includes the intent translation interface and capability call interface between the network application layer and the twin network layer. The network application layer can pass the application layer intent to the twin network layer through the intent translation interface, providing abstract demand input for the functional model.

[0033] (3) Twin internal interface: including a cluster of interfaces such as the interface between the internal data warehouse and the functional model of the twin network layer, the interface between the functional model and the digital twin management, and the interface between functional models.

[0034] To perform virtual mapping between physical network and digital twin network, it is necessary to first define the digital twin network model for physical network mapping. DTN service mapping model includes two categories: basic model and functional model. Figure 2 As shown, Figure 2 Schematic diagram of digital twin network model classification.

[0035] (1) Basic model

[0036] The foundational model is a virtual twin of the physical network, built based on information such as network element functional configuration, operating status, network topology, network traffic, and network performance. It is used to accurately describe the physical network. The foundational model includes the network element model and the network topology model.

[0037] The network element model is a model of physical network devices, such as server models, switch models, and firewall models, to achieve twinning of physical network elements. The network topology model is used to represent the physical network topology and the network traffic and performance status based on the topology.

[0038] (2) Functional model

[0039] A functional model is a model that implements specific functions for a specific application scenario. Functional models can be constructed and extended across multiple dimensions. Combining these dimensions creates data models tailored to specific scenarios. For example, a traffic balancing optimization model can be built on core switches in a data center network. Functional models are instantiated and applied to the base model.

[0040] Figure 3Schematic diagram of the classification of digital twin network functional models.

[0041] Figure 4 A schematic diagram of the structure of a network management service architecture for implementing digital twin services provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the network management service architecture for implementing digital twin services provided in this embodiment includes: a communication network management system 41 and a digital twin control system 42.

[0042] The communication network management system 41 is configured to obtain network management service demand information and manage the digital twin objects of the physical communication network 43 through the digital twin management service provided by the digital twin control system 42; the digital twin control system 42 is configured to perform management of the digital twin object instances of the physical communication network 43 based on the digital twin management service requirements of the communication network management system 41 for the digital twin objects.

[0043] Communication network management system 41 can obtain network management service demand information from communication service provider (or operator) 44. Physical communication network 43 is deployed and operated by communication service provider 44, so communication service provider 44 manages physical communication network 43 through communication network management system 41. Communication network management system 41 can be, for example, a 3GPP management system. Digital twin control system 42 is the management entity of the digital twin object and is responsible for executing management of the digital twin object of physical communication network 43 under the control of communication network management system 41.

[0044] Alternatively, the communication service provider 44, the communication network management system 41, the digital twin control system 42, and the physical communication network 43 can be used as functional modules of the network management service architecture for implementing the digital twin service. Among them, the communication network management system 41 serves as the management service consumer (Management Service Consumer, Mns Consumer) of the digital twin service architecture, and the digital twin control system 42 serves as the management service producer (Management Service Producer, Mns Producer) of the digital twin service architecture. The interface between the communication network management system 41 and the digital twin control system 42 is the digital twin management service interface (DT MnS), the interface between the digital twin control system 42 and the physical communication network is the digital twin virtual-reality interaction interface, and the interface between the communication network management system 41 and the physical communication network 43 is the operation administration and maintenance (OAM) interface.

[0045] As a user of digital twin services, communications service provider 44 can, based on the simulation, prediction, and decision-making capabilities of the digital twin network, propose digital twin service requirements for scenarios such as network planning, network design, network maintenance, network optimization, and business operations. These requirements can be used for applications such as network optimization, new business deployment, network fault and risk prediction, and root cause analysis of network faults.

[0046] The communication network management system 41 is used to parse the requirements from the communication service provider 44 into digital twin capability service task descriptions and digital twin object instance requirements. As a consumer of the digital twin management service, the communication network management system 41 calls the digital twin management service interface to perform lifecycle management of digital twin object instances and provides services such as digital twin-related simulation evaluation. Digital twin management services include twin object instance lifecycle management services, digital twin object instance selection services, digital twin capability services (including network visualization, network optimization, fault and risk prediction, fault location and avoidance, new business deployment and other simulation evaluation tasks), virtual-reality interactive optimization services, etc.

[0047] The digital twin control system 43 creates and configures a digital twin object instance according to the digital twin network object management requirements and configuration description, and then runs the digital twin capability service task on the instance, performs simulation and evaluation operations, and outputs the simulation and evaluation results, which are not limited to simulation and evaluation reports, network optimization strategies, promoted network solutions, etc.

[0048] In one embodiment, the digital twin control system 42 is specifically configured to perform management of the digital twin objects of the physical communication network on the digital twin object instances of the physical communication network 43 according to the digital twin management service requirements, and to feedback the management results to the communication network management system 41.

[0049] The network management service architecture for implementing digital twin services can also include a digital twin platform 45, which is used to carry digital twin object instances, a digital twin control system 42, which is specifically configured to describe the digital twin object instances based on the physical communication network 43, and instantiate digital twin objects on the digital twin platform 45 to obtain digital twin object instances.

[0050] In one embodiment, the digital twin control system 42 is further configured to collect network data of the physical communication network 43 before creating a digital twin object instance of the physical communication network 43, create a digital twin entity model of the physical communication network 43, and create a digital twin object instance of the physical communication network 43 based on the digital twin entity model of the physical communication network 43.

[0051] In one embodiment, the communication network management system 41 is specifically configured to parse the acquired digital twin service demand information into a digital twin capability service task description, a digital twin object instance demand description, or a digital twin object instance configuration description.

[0052] In one embodiment, the communication network management system 41 is specifically configured to perform simulation evaluation operations of digital twin object instances according to the digital twin capability service task description, or to perform creation and update operations of digital twin object instances according to the digital twin object instance requirement description or the digital twin object instance configuration description.

[0053] In one embodiment, the communication network management system 41 is further configured to query the digital twin object instance created by the digital twin control system 42, and select the created digital twin object instance to perform management of the digital twin object.

[0054] The communication network management system 41 is also configured to issue network operation and maintenance strategies to the physical communication network 43 and receive network operation and maintenance feedback from the physical communication network 43. If the network operation and maintenance feedback fails to meet the expected goals, the digital twin management system 42 interacts with the physical communication network 43 to simulate and iterate the network operation and maintenance strategies until the expected goals are met.

[0055] The communication network management system 41 is also configured to issue network operation and maintenance strategies to the digital twin management system 42; the digital twin management system 42 is also configured to request the physical communication network 43 to execute the network operation and maintenance strategies, and receive network operation and maintenance feedback from the physical communication network 43. If the network operation and maintenance feedback does not meet the expected goals, it interacts with the physical communication network 43, simulates and iterates the network operation and maintenance strategies until the expected goals are met, and sends the updated network operation and maintenance strategies to the communication network management system 41.

[0056] The digital twin management service for the digital twin object of the physical communication network 43 includes any of the following management services for the digital twin object: creating a digital twin object instance, updating a digital twin object instance, activating a digital twin object instance, deactivating a digital twin object instance, deleting a digital twin object instance, and performing simulation evaluation operations on a digital twin object instance.

[0057] The network management service architecture for implementing digital twin services provided in the embodiments of the present application, by configuring a network management service architecture composed of a communication network management system and a digital twin control system, enables communication service providers to implement digital twin management services through the communication network management system, realize the virtual-reality interaction between digital twin services and physical communication networks, and better meet the management needs of verifying network operation and maintenance solutions for digital twin technology.

[0058] Figure 5A flowchart of a network management service method for implementing a digital twin service is provided in an embodiment of the present application, such as Figure 5 As shown, the network management service method for implementing the digital twin service provided in this embodiment includes:

[0059] Step S110: The communication network management system obtains network management service demand information.

[0060] The network management service method for implementing digital twin services provided in this embodiment is applied to Figure 4 The network management service architecture for implementing digital twin services is shown in Figure 4 The network management service architecture shown here implements digital twin services, providing digital twin services for physical communication networks. The communication network management system can obtain network management service demand information from communication service providers. Without the introduction of digital twin services, the communication network management system would manage the physical communication network based on network management service demand.

[0061] Step S120: The communication network management system sends a digital twin management service requirement for the digital twin object of the physical communication network to the digital twin control system.

[0062] After the introduction of the digital twin service, the communication network management system sends a request for digital twin management services for the physical communication network's digital twin object to the digital twin control system, effectively assisting in the management of the physical communication network through the digital twin service. Based on this network management service request information, the communication network management system determines the need to manage the digital twin object corresponding to the physical communication network. This means parsing the network management service request information to enable management of the physical communication network through the digital twin object.

[0063] In step S130 , the digital twin control system manages the digital twin objects of the physical communication network according to the digital twin management service requirements of the digital twin objects of the physical communication network.

[0064] The digital twin control system is responsible for the comprehensive management of digital twin objects, including creating and configuring digital twin object instances based on the digital twin network object requirements and configuration descriptions, then running digital twin capability service tasks on the instances, performing simulation and evaluation operations, and outputting simulation and evaluation results, including but not limited to simulation and evaluation reports, network optimization strategies, and promoted network solutions.

[0065] In one embodiment, the digital twin control system performs management of the digital twin objects of the physical communication network on the digital twin object instances of the physical communication network based on the digital twin management service requirements for the digital twin objects of the physical communication network, and feeds back the management results to the communication network management system.

[0066] In one embodiment, the digital twin control system instantiates the digital twin object on the digital twin platform according to the digital twin object instance description of the physical communication network to obtain the digital twin object instance.

[0067] In one embodiment, before creating a digital twin instance of the physical communication network, the digital twin control system collects network data of the physical communication network, creates a digital twin entity model of the physical communication network, and creates a digital twin object instance of the physical communication network based on the digital twin entity model of the physical communication network.

[0068] In one embodiment, the communication network management system obtains network management service demand information and parses the network management service demand information into a digital twin capability service task description, a digital twin object instance demand description, or a digital twin object instance configuration description.

[0069] In one embodiment, the digital twin control system performs simulation evaluation operations of the digital twin object instance according to the digital twin capability service task description, or performs creation and update operations of the digital twin object instance according to the digital twin object instance requirement description or the digital twin object instance configuration description.

[0070] In one embodiment, the communication network management system queries the digital twin object instances created by the digital twin control system, and selects the created digital twin object instances to perform management of the digital twin objects.

[0071] In one embodiment, the communication network management system issues a network operation and maintenance strategy to the physical communication network and receives network operation and maintenance feedback from the physical communication network. If the network operation and maintenance feedback does not meet the expected goals, the digital twin management system interacts with the physical communication network to simulate and iterate the network operation and maintenance strategy until the expected goals are met.

[0072] In one embodiment, the communication network management system issues a network operation and maintenance strategy to the digital twin management system; the digital twin management system requests the physical communication network to execute the network operation and maintenance strategy, and receives network operation and maintenance feedback from the physical communication network. If the network operation and maintenance feedback does not meet the expected goals, it interacts with the physical communication network, simulates and iterates the network operation and maintenance strategy until the expected goals are met, and sends the updated network operation and maintenance strategy to the communication network management system.

[0073] In one embodiment, the digital twin object management service includes any of the following: creating a digital twin object instance, updating a digital twin object instance, activating a digital twin object instance, deactivating a digital twin object instance, deleting a digital twin object instance, and performing simulation evaluation operations on a digital twin object instance.

[0074] The network management service method for implementing digital twin services provided in the embodiment of the present application is based on a network management service architecture composed of a communication network management system and a digital twin control system. The communication network management system obtains network management service demand information; the communication network management system sends the digital twin management service demand for the digital twin object of the physical communication network to the digital twin control system; the digital twin control system performs management of the digital twin object instance of the physical communication network based on the digital twin management service demand for the digital twin object of the physical communication network, so that the communication service provider can implement digital twin management services through the communication network management system, realize virtual and real interaction between digital twin services and physical communication networks, and better meet the management needs of verifying network operation and maintenance solutions for digital twin technology.

[0075] The following describes in detail the specific process of implementing various digital twin service management on the network management service architecture for implementing digital twin services provided in the embodiments of the present application. In the following embodiments, the communication network management system is described as a 3GPP management system as an example.

[0076] Figure 6 An interactive flowchart for creating a digital twin object instance for the network management service architecture that implements the digital twin service provided in an embodiment of the present application.

[0077] like Figure 6 As shown, this embodiment describes how the 3GPP management system invokes the digital twin management service of the digital twin control system and uses the digital twin instance to simulate and evaluate related digital twin services. Digital twin services may include network visualization, network optimization, fault and risk prediction, root cause analysis and resolution strategies, and new service deployment evaluation. The digital twin control system creates the digital twin instance required for the digital twin service, simulates and evaluates the digital twin service on the instance, and then feeds the results back to the 3GPP management system. These results include, but are not limited to, simulation and evaluation reports, network optimization strategies, and recommended network solutions.

[0078] Step S201: Before officially deploying services on the physical network, communications service providers need to simulate and evaluate digital twin services for various digital twin applications using digital twin instances to mitigate the risks of direct deployment on the physical network. Digital twin services may include network visualization, network optimization, fault and risk prediction, root cause analysis and resolution strategies, and new service deployment assessment. The communications service provider requests a digital twin service from the 3GPP management system. This request message includes a service identifier, service type, service parameters, and a description of service requirements. Services may include network visualization, network optimization, fault and risk prediction, root cause analysis and resolution strategies, and new service deployment assessment. Service parameters include network configuration parameters and required performance parameters, and the service requirements description includes a description of the network's functional requirements.

[0079] Step S202: The 3GPP management system parses the digital twin application service requirements from the communication service provider, and parses the service type, service parameters and requirement description into two parts: digital twin capability service task description, twin object instance requirement description and instance configuration description. The digital twin capability service task description includes the simulation evaluation capabilities of various network optimization solutions provided by the digital twin platform, such as network visualization related to network operation and maintenance, network fault location and fault avoidance, network fault and risk prediction, network optimization, and digital twin simulation evaluation operations for new business deployment. The twin object instance requirement description includes the twin object model requirements, the user scale of the twin object instance, the environment and other constraints, etc. The twin object instance configuration description includes the resources and applications of each network element in the twin object instance.

[0080] Step S203: First, the 3GPP management system requests the digital twin control system to create a digital twin object instance, and sends the twin object instance requirement description to the digital twin control system.

[0081] Step S204: The digital twin control system interacts with the physical system, collects data to create twin entity models such as twin entities mapped to each physical entity in the model, twin functions mapped to each network function, and twin topologies mapped to the physical entity topology.

[0082] Step S205: The digital twin control system creates a digital twin object instance based on the twin object instance requirement description and the various twin entity models that have been created. The instance corresponds to part or all of the required physical network, or part or all of the network element entity.

[0083] Step S206: The digital twin control system sends a digital twin object instance creation success message to the 3GPP management system, and the message carries an instance identification indication.

[0084] Step S207: The 3GPP management system sends the digital twin object instance configuration description file to the digital twin control system to perform resource configuration and application loading for the instance.

[0085] Step S208: After the configuration is completed, the 3GPP management system creates the required digital twin capability service tasks based on the service analysis.

[0086] Step S209: The 3GPP management system issues the required digital twin capability service task to the digital twin control system, requesting the execution of simulation and evaluation operations for various network strategies and solutions, such as network optimization, within the management service task. This message carries the service task information, a task identifier, and the corresponding instance identifier.

[0087] Step S210: The digital twin control system inputs historical and current data collected from the physical network, such as live RAN and CN network data, into the instance, simulates the actual network operation scenario, and performs simulation evaluation and other required operations. After the operation is completed, the generated various results are returned to the 3GPP management system. The result information is not limited to simulation and evaluation reports, network optimization strategies, and recommended solutions.

[0088] Step S211: The 3GPP management system creates a service report and feeds back the simulation evaluation results to the communication service provider through the service report.

[0089] Figure 7 An interactive flowchart for updating digital twin object instances in a network management service architecture that implements digital twin services provided in an embodiment of the present application.

[0090] like Figure 7 As shown, this embodiment describes the 3GPP management system updating the created twin object instance, providing digital twin management services for the updated digital twin services, and updating the digital twin capability service tasks to re-simulate and evaluate the updated digital twin services.

[0091] Step S301: The communications service provider updates part or all of the service type, service parameters, and service requirements description of the digital twin service based on the feedback from the digital twin service report. The communications service provider requests the 3GPP management system to update the digital twin service. The request message includes the service identifier, the updated service type, service parameters, and service requirements description.

[0092] Step S302: The 3GPP management system re-parses the updated digital twin service requirements from the communication service provider, and updates the created digital twin capability service task description, twin object instance requirement description and twin object instance configuration description based on the updated service type, service parameters and requirement description.

[0093] Step S303: The 3GPP management system requests the digital twin control system to update the digital twin object instance, and sends the updated twin object requirements and the created instance ID to the digital twin control system.

[0094] Step S304: Optionally, based on the requirements of the updated twin object instance, if it is necessary to update or add a twin entity model, the digital twin control system needs to interact with the physical system to collect data to create twin entity models mapping each physical entity in the model, twin functions mapping each network function, and twin topology mapping the physical entity topology.

[0095] Step S305: The digital twin control system updates the digital twin object instance according to the updated twin object instance requirement description and the newly created or updated twin entity models, which corresponds to part or all of the required physical network or part or all of the network element entity.

[0096] Step S306: The digital twin control system sends a digital twin object instance update success message to the 3GPP management system, and the message carries an instance identification indication.

[0097] Step S307: The 3GPP management system sends the updated digital twin object instance configuration description file to the digital twin control system to update the resource configuration of the instance and the loading of the application.

[0098] Step S308: After the configuration is completed, the 3GPP management system updates the created digital twin service task according to the service analysis results.

[0099] Step S309: The 3GPP management system issues the required digital twin management capability service task to the digital twin control system, requesting the execution of the service task, including simulation and evaluation of various network strategies and solutions, such as network optimization. This message carries the service task information, a task identifier, and the corresponding instance identifier.

[0100] Step S310: The digital twin control system inputs historical and current data collected from the physical network, such as live RAN and CN network data, into the instance, simulates the actual network operation scenario, and re-runs simulation and evaluation operations. After the operation is completed, the generated results are returned to the 3GPP management system. The results include but are not limited to simulation and evaluation reports, network optimization strategies, and recommended network solutions.

[0101] Step S311: The 3GPP management system creates a service report and feeds back the simulation evaluation results to the communication service provider through the service report.

[0102] Figure 8An interactive flowchart of the digital twin management service and instance deactivation process of the network management service architecture for implementing the digital twin service provided in the embodiment of the present application.

[0103] like Figure 8 As shown, this embodiment describes that for a twin object instance that has not executed a digital twin service task for a long time, because it occupies simulation resources, the 3GPP management system needs to deactivate the instance and release the occupied service resources.

[0104] Step S401a: The communication service provider no longer needs to request the digital twin service within a period of time based on the demand for the digital twin service, so it stops the digital twin service to the 3GPP management system, carrying the service id indication. After receiving the stop service request, the 3GPP management system decides to release the resources occupied by the instance. Or,

[0105] Step S401b: The 3GPP management system starts the service task timer after the service task simulation is completed. If the server overflows, it means that the instance has not executed the service task for a long time and the resources occupied by the instance need to be released.

[0106] Step S402: The 3GPP management system requests the digital twin control system to deactivate the created twin object instance, carrying the instance identifier.

[0107] Step S403: The digital twin control system releases the resources occupied by the instance, marks the instance as being in a deactivated state, and then returns a message indicating that the instance has been deactivated to the 3GPP management system.

[0108] Step S404: The 3GPP management system returns to the communication service provider that the digital twin service has been stopped.

[0109] Figure 9 An interactive flowchart of the digital twin management service and instance deletion process of the network management service architecture for implementing the digital twin service provided in the embodiment of the present application.

[0110] like Figure 9 As shown, this embodiment describes the operation of deleting a twin object instance that is no longer needed to execute a digital twin service task, completely releasing the instance.

[0111] Step S501: The communications service provider no longer needs to execute the digital twin service and requests the 3GPP management system to delete the digital twin service, carrying the service identifier.

[0112] Step S502: After receiving the digital twin service deletion request, the 3GPP management system requests the digital twin control system to delete the created twin object instance, carrying the corresponding instance identifier.

[0113] Step S503: The digital twin control system deletes the instance, releases the resources of the instance, deletes the entity model, object model and related data corresponding to the instance, and then returns the deletion of the instance to the 3GPP management system.

[0114] Step S504: The 3GPP management system deletes all relevant information of the instance, and then returns to the communication service provider that the digital twin service has been deleted.

[0116] like Figure 10 As shown, this embodiment describes the 3GPP management system receiving a digital twin service request from a communication service provider and converting the service request into a twin object requirement and configuration file, as well as a digital twin capability service task. Based on the scenario where multiple twin object instances already exist, the instance does not need to be newly created. The 3GPP management system selects an already created twin object instance based on similar twin object requirements and updates the instance and configuration to meet the requirements of running the new digital twin capability service task.

[0117] Step S601: The communication service provider requests a digital twin service from the 3GPP management system. The request message includes a service identifier, service type, service parameters, and service requirement description information. (Same as step S201)

[0118] Step S602: The 3GPP management system parses the digital twin service requirements from the communication service provider, and parses the service type, service parameters and requirement description into a digital twin capability service task description file, a twin object requirement description and an instance configuration description file.

[0119] Step S603: In a scenario where there are multiple idle twin object instances in the digital twin control system (such as multiple deactivated twin object instances), the 3GPP management system queries the digital twin control system for information on idle twin object instances, including twin object models and configurations.

[0120] Step S604: The digital twin control system returns information of multiple idle twin object instances, including the twin object model and configuration information of the instance, instance ID, etc.

[0121] Step S605: The 3GPP management system compares the twin object model a parsed by the service with the twin object model b of the created instance, and selects the twin object instance. The selection principle is: preferred - model b and model a have related twin entities and twin topologies, suboptimal - the twin entities and twin topologies of model b can cover model a. The 3GPP management system selects an optimal twin object instance and updates the configuration file of the object instance according to the digital twin service requirements. If no selection is possible, the process of instance 2 is adopted to create a new twin object instance.

[0122] Step S606: The 3GPP management system requests the digital twin control system to update the configuration of the twin object instance, carrying the configuration file of the updated object instance and the instance identifier.

[0123] Step S607: The digital twin control system performs resource configuration and application updates on each twin entity of the instance based on the updated twin object configuration information.

[0124] Step S608: After the configuration update of the twin object instance is completed, the digital twin control system notifies the instance that the update has been successful, carrying the instance identifier.

[0125] Step S609: The 3GPP management system creates the required digital twin capability service tasks based on the service analysis.

[0126] Step S610: The 3GPP management system sends the required digital twin service task to the digital twin control system, requesting simulation and evaluation operations. The message carries the service task information, the task identifier, and the instance identifier.

[0127] In step S611, the digital twin control system inputs historical and current data collected from the physical network, such as live RAN and CN network data, into the instance, simulates the actual network operation scenario, and performs simulation evaluation and other required operations. After the operation is completed, the generated various results are returned to the 3GPP management system. The result information is not limited to simulation and evaluation reports, network optimization strategies, and optional recommended network solutions.

[0128] Step S612: The 3GPP management system creates a service report and feeds back the simulation evaluation results to the communication service provider through the service report.

[0129] Figure 11 The network management service architecture for implementing digital twin services provided in the embodiment of the present application is an interactive flowchart for performing strategy optimization through a digital twin control system when the network strategy in the network does not meet expectations.

[0130] like Figure 11As shown, this embodiment describes a network operation and maintenance solution that has been verified by the digital twin service, such as a network optimization strategy or new business deployment. The communication service provider deploys the strategy or new business on the physical network. The physical network feeds back the operation results to the digital twin control system for evaluation. If the evaluation does not meet expectations, the digital twin control system decides to start the virtual-real interactive optimization service, re-simulates and evaluates by collecting live network data, and modifies the network operation and maintenance solution, such as modifying the network optimization strategy to achieve better network performance. The digital twin network sends the optimized network strategy to the physical network for trial operation, and cyclically executes the evaluation and optimization simulation iterations until the network operation and maintenance solution meets expectations when running on the physical network.

[0131] Step S701: The communications service provider decides to deploy a network operation and maintenance solution verified by the digital twin service on the physical network, such as a network optimization strategy or new service deployment. The communications service provider requests the 3GPP management system to run the network operation and maintenance solution verified by the digital twin service on the physical network, carrying the service ID.

[0132] Step S702: The 3GPP management system requests the digital twin control system to issue a network operation and maintenance plan corresponding to the service ID.

[0133] Step S703: The digital twin control system sends a network operation and maintenance plan, such as a network optimization strategy, to the physical network, and requires the physical network to run the network optimization strategy.

[0134] Step S704: The physical network runs the network operation and maintenance solution, such as the network optimization strategy, and feeds back the actual network status after the operation to the digital twin network, such as the actual network performance parameters.

[0135] Step S705: The digital twin control system evaluates whether the network operation and maintenance plan meets expectations based on the actual network status reported by the physical network. If so, it reports this to the 3GPP management system. If not, the digital twin control system initiates a virtual interactive optimization operation. Through virtual-real interaction with the physical network, data is exchanged and verified. After revising the network strategy, it re-simulates and iterates the twin instance until it meets expectations.

[0136] Step S706: Optionally, the digital twin control system requests to roll back the executed network policy.

[0137] Step S707: The digital twin control system interacts with the physical network. The digital twin control system collects actual operational data from the live network, modifies the network policy, and re-simulates the digital twin object instance. The updated policy, which optimizes network performance, is then distributed to the physical network for verification. The physical network then provides feedback on the post-operation network status. The digital twin control system then updates the network policy and iterates the simulation optimization process until the physical network performs as expected.

[0138] Step S708: The digital twin control system provides feedback to the 3GPP network that the network operation and maintenance plan has met expectations in the physical network operation, and carries the updated network operation and maintenance plan, such as the updated network optimization strategy.

[0139] Step S709: The 3GPP management system notifies the communication provider that the network operation and maintenance solution has met expectations in the physical network.

[0140] Figure 12 The network management service architecture for implementing digital twin services provided in the embodiment of the present application is an interactive flowchart for performing strategy optimization through the 3GPP management system when the network strategy in the network network operation does not meet expectations.

[0141] like Figure 12 As shown, this embodiment describes a network operation and maintenance solution that has been verified by a digital twin service, such as a network optimization strategy or new business deployment. The communication service provider deploys the strategy or new business on the physical network through the 3GPP management system. The physical network will feed back the operation results to the 3GPP management system for evaluation. If the evaluation does not meet expectations, the 3GPP management system decides to start a virtual interactive optimization service. The 3GPP management system updates the service task description, improves the network function and performance parameter expectations in the service task description, and the digital twin control system re-collects the existing network data and re-optimizes according to the updated service tasks to obtain a better network strategy. The digital twin network sends the updated network strategy to the physical network for trial operation, and starts the simulation iteration of evaluation and optimization until the network operation and maintenance solution meets expectations in the physical network operation.

[0142] Step S801: The communication service provider decides to deploy a network operation and maintenance solution verified by the digital twin service on the physical network, such as a network optimization strategy or new service deployment. The communication service provider requests the 3GPP management system to run the network operation and maintenance solution verified by the digital twin service on the physical network, carrying the service ID.

[0143] Step S802: The 3GPP management system sends a network operation and maintenance solution corresponding to the service ID, such as a network optimization strategy, to the physical network, and requires the physical network to run the network optimization strategy.

[0144] Step S803: The physical network runs the network operation and maintenance solution, such as a network optimization strategy, and feeds back the state of the network after the operation to the 3GPP management network, such as actual network performance parameters.

[0145] Step S804: The 3GPP management system evaluates whether the network operation and maintenance solution meets expectations based on the actual status fed back by the physical network.

[0146] Step S805a: If the evaluation meets expectations, the 3GPP management system provides feedback to the communication service provider that the network operation and maintenance plan has met expectations.

[0147] Step S805b: If the evaluation does not meet expectations, the 3GPP management system requests the physical network to roll back the executed network policy.

[0148] Step S806: The 3GPP management system decides to start the virtual interactive optimization service: the 3GPP management system updates the digital twin capability service task (such as improving the expected network functions and performance in the task description), the digital twin control system interacts with the physical network in a virtual and real manner, the digital twin control system collects actual data from the existing network and performs simulation, and generates a new network operation and maintenance plan based on the simulation results. The 3GPP management system re-issues the new operation and maintenance plan to the physical network for verification until it meets expectations.

[0149] Step S807: After the 3GPP management system updates the digital twin capability service task, it sends the updated service task to the digital twin control system, requesting the execution of simulation iterations. The message carries the updated service task, task ID, and corresponding instance ID.

[0150] Step S808: The digital twin control system interacts with the physical network. The digital twin control system collects actual operational data from the live network, re-simulates the digital twin object instance based on the updated service tasks, and generates a new network operation and maintenance plan. The digital twin control system uploads the new network operation and maintenance plan to the 3GPP network system, which then re-distributes the new network operation and maintenance plan to the physical network for verification. The physical network then provides feedback on the post-operation network status. This iterative process of steps S804 to S807 continues until the physical network achieves the expected operation.

[0151] Step S809: The 3GPP management system notifies the communication provider that the network operation and maintenance solution has met expectations in the physical network.
