[0002] This disclosure claims priority to Chinese Patent Application No. 202411444181.7, filed in China on October 16, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of network technology, and in particular to a digital twin service orchestration method, system, device, storage medium, and product. Background Technology

[0004] A Digital Twin Network (DTN) is a simulation environment orchestrated from multiple twin models built based on physical entities. It can interact and map with physical entities in real time and provide different twin services to consumers. Because the types of twin services differ—such as data generation, simulation tasks, pre-verification, and AI interaction environments—the requirements for the twin network vary across scenarios, including the frequency of interaction with the physical network, the granularity of the twin, and the twin models involved in the orchestration. Therefore, dynamic, on-demand orchestration of models is crucial for the operation of a digital twin. It requires building twin services tailored to differentiated needs, simultaneously meeting diverse requirements and improving service efficiency. However, commonly used digital twin service orchestration methods primarily implement coarse-grained orchestration of the overall digital twin environment and perform simulations based on the overall twin environment. They cannot provide fine-grained twin services in parallel according to the differentiated twin task requirements, lacking on-demand orchestration methods for multiple twin services in parallel. This results in the need to consume enormous resources such as communication and computing power to build the network digital twin system. Summary of the Invention

[0005] The purpose of this disclosure is to provide a digital twin service orchestration method, system, device, storage medium, and product that adopts a parallel service mode and dynamically orchestrates the twin service chain on demand according to different service requirements, providing accurate and refined twin services without consuming huge resources such as communication and computing power to build a network digital twin system.

[0006] To achieve the above objectives, embodiments of this disclosure provide a digital twin service orchestration method, including:

[0025] The service orchestration function is used to receive the second quality of service requirement sent by the twin service management function, determine the target domain for which the twin service needs to be executed, and send the second quality of service requirement to the sub-service orchestration function corresponding to the target domain.

[0028] As an improvement to the above scheme, the sub-service orchestration function is used to find the corresponding target twin model among several registered twin models based on the network element name and the second quality of service requirement.

[0029] As an improvement to the above scheme, each single domain network element corresponds to a sub-service orchestration function;

[0030] When the target domain is a single-domain network element, the sub-service orchestration function performs parallel orchestration of the target twin model corresponding to the twin task request according to the topology relationship, so as to generate the corresponding twin service chain;

[0038] As an improvement to the above scheme, both the twin service management function and the service orchestration function are deployed in the operation management and maintenance system, with one sub-service orchestration function deployed in the base station and the other sub-service orchestration function deployed in the core network.

[0048] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0049] Referring to Figure 1, which is a flowchart of a digital twin service orchestration method provided in an embodiment of this disclosure, the digital twin service orchestration method is implemented by digital twin service orchestration execution, and the method includes:

[0050] S1. Receive at least one twin task request sent by the requester; wherein the twin task request carries the requester's first service quality requirement for the twin service;

[0051] S2. Map the first service quality requirement to the second service quality requirement for the twin service chain;

[0052] S3. Based on the second service quality requirement, find the corresponding target twin model among the registered twin models;

[0053] S4. Request the target twin model from the corresponding twin model library, and perform parallel orchestration on the target twin model corresponding to the twin task request to generate a parallel twin service chain.

[0054] For example, by parsing the twin task request sent by the demand side, a first service quality requirement is obtained. This first service quality requirement is then mapped to a second service quality requirement for the twin service chain. Based on the second service quality requirement request conforming to the target twin model of the twin task, a corresponding twin service chain is orchestrated and generated to provide twin services. Since a parallel service mode is adopted to generate corresponding twin service chains according to different twin task requests, and twin service chains are dynamically orchestrated on demand according to different service requirements, accurate and refined twin services are provided, thus eliminating the need to consume massive resources such as communication and computing power to build a network digital twin system.

[0055] Referring to Figure 2, which is a structural block diagram of a digital twin service orchestration system provided in an embodiment of this disclosure, the digital twin service orchestration system includes a twin service management function, a service orchestration function, and at least one sub-service orchestration function. Steps S1 to S2 are executed by the twin service management function, step S3 is executed by the sub-service orchestration function, and step S4 is executed by either the service orchestration function or the sub-service orchestration function. The functions of each module are as follows:

[0056] The Twin Service Management Function (TSMF) is used to receive twin task requests sent by the requester. The twin task request carries the requester's first service quality requirement for the twin service. It is also used to map the first service quality requirement to a second service quality requirement for the twin service chain.

[0057] The service orchestration function, hereinafter referred to as TNSOF (Twin Network Service Orchestration function), is used to receive the second quality of service requirement sent by the twin service management function, determine the target domain for which twin services need to be executed, and send the second quality of service requirement to the sub-service orchestration function corresponding to the target domain.

[0058] At least one subservice orchestration function, hereinafter referred to as the Twin network subService Orchestration function (TNSSOF), is used to find the corresponding target twin model among several registered twin models according to the second quality of service requirement, and to perform parallel orchestration on the target twin model corresponding to the twin task request to generate a parallel twin service chain.

[0059] For example, the main function of TSMF is to parse the Quality of Service (QoS) requirements of the twin task request and parse the network elements (i.e., the network elements where the twin model is located) and topology relationships involved in the twin task. It converts the consumer's QoS requirements (first QoS requirements) into twin service chain QoS-related requirements (second QoS requirements) and then sends them to TNSOF.

[0060] For example, the main function of TNSOF is to orchestrate and manage the models, computing resources, and communication resources of twin tasks. Specifically, it includes: 1) determining whether the target domain involved in the twin task is the Radio Access Network (RAN) domain or the Core Network (CN) domain; 2) distributing the twin task to the sub-service orchestration functions corresponding to the RAN domain and the CN domain; 3) if the twin task involves cross-domain (i.e., both RAN and CN domains exist simultaneously), it needs to request the corresponding target twin model from each domain, and then perform twin service chain orchestration to complete the twin task; 4) twin model construction and management. In addition to the network element twin model (including modeling of physical attributes, functions, and performance), the twin environment also needs to have protocol models, AI decision models, etc. TNSOF is responsible for the construction, updating, management, and orchestration of other twin models besides the network element twin model.

[0061] For example, assume there are two Sub-Service Orchestration Functions (TNSSOFs): one for the RAN domain (RAN-TNSSOF) and one for the CN domain (CN-TNSSOF). The RAN-TNSSOF's main function is to manage the twin service orchestration (including model orchestration, computational resource orchestration, and communication resource orchestration) of the Radio Access Network (RAN). Based on the task requirements issued by the TNSOF, it requests twins of relevant network elements from the RAN, orchestrates them according to the resolved scenario topology, and processes twin tasks based on the orchestrated twin service chains. The CN-TNSSOF's main function is to manage the twin service orchestration (including model orchestration, computational resource orchestration, and communication resource orchestration) of the Core Network (CN). Based on the task requirements issued by the TNSOF, it requests twins of relevant network elements from the CN, orchestrates them according to the resolved scenario topology, and processes twin tasks based on the orchestrated twin service chains.

[0062] Furthermore, digital twin (DT) network elements are added to RAN and CN. While having network element entities, RAN and CN also have a digital twin model (DT model), which can be updated in real time based on physical network data.

[0063] Specifically, there are two ways to deploy the various functions in the digital twin service orchestration system: one is centralized deployment, and the other is separate deployment.

[0064] In the first implementation, both the Twin Service Management Function (TSMF) and the Service Orchestration Function (TNSOF) are deployed in the Operation Administration and Maintenance (OAM) system. One sub-service orchestration function is deployed at the base station, such as RAN-TNSSOF deployed at the gNB, and the other sub-service orchestration function is deployed in the core network, such as CN-TNSSOF deployed at the CN, existing as a network element in the CN.

[0065] In the second implementation, the twin service management function TSMF, the service orchestration function TNSOF, and all sub-service orchestration functions (i.e., RAN-TNSSOF and CN-TNSSOF) are deployed in the operation management and maintenance system OAM.

[0066] Furthermore, taking the digital twin service orchestration system with two sub-service orchestration functions as an example, each functional module in the digital twin service orchestration system has a first interface, a second interface, and two third interfaces. The number of third interfaces corresponds one-to-one with the number of sub-service orchestration functions. The data transmitted by the four interfaces is as follows:

[0067] 1) The first interface is the interface between TSMF and external entities (such as consumers), mainly used to transmit twin task requests. The twin task request carries the following information: {Scene type, TSST=N, DQTI}.

[0068] 1.1) Scene type indicates the network scene type. Different task requests have corresponding network scene types, such as face recognition scene, data collaboration scene, video conferencing scene, etc.

[0069] 1.2) TSST (Twin Service Type) represents the twin service chain type, and N represents the twin service type number. For example: TSST=1 represents the data generation service; TSST=2 represents the policy pre-validation service; TSST=3 represents the visualization service.

[0070] 1.3) DQTI (Digital Twin QoS Identifier) ​​represents the first quality of service requirement of the demand party for the twin service, which is determined based on the twin service chain type. The DQTI differs for each TSST. For example, for TSST=1, it includes at least {Data accuracy, generation delay, data volume}; for TSST=2, it includes at least {validation accuracy, validation delay}; and for TSST=3, it includes at least {Visual type: {2D, 3D}, resolution, interaction, rendering speed}.

[0071] 2) The second interface is the interface between the Twin Service Management Function (TSMF) and the Service Orchestration Function (TNSOF). It is mainly used to transmit the parsed twin service orchestration requirements. The twin service orchestration requirements include network element names (NF names), topology relations, and the second quality of service requirements of the twin service chain. The network element names refer to the names of the network elements involved in the network scenario, the topology relations refer to the topology relations between twin models, and the second quality of service requirements of the twin service chain are related to the twin service chain type (TSST) in the twin task request. For example, when TSST=1, the first quality of service requirements are data accuracy, generation latency, and data volume, and the second quality of service requirements of the twin service chain can be the granularity, inference ability, and real-time performance of the twin model.

[0072] 3) The third interface 1 is used to transmit messages between TNSOF and RAN-TNSSOF. The messages transmitted from RAN-TNSSOF to RAN include at least the RAN NF name and topology relation. Among them, RAN transmits model registration information to RAN-TNSSOF.

[0073] 4) The third interface 2 is used to transmit messages between TNSOF and CN-TNSSOF. The messages transmitted from CN-TNSSOF to CN include at least the CN network element name and topology relation. CN transmits model registration information to CN-TNSSOF.

[0074] For example, referring to Figure 3, which is another flowchart of a digital twin service orchestration method provided in this disclosure embodiment, the working process of each module in the digital twin service orchestration system is described in detail with reference to the steps shown in Figure 3, including steps 1 to 14:

[0075] 1a-1b, any of the sub-service orchestration functions is further used to receive and store model registration information sent by the corresponding twin model library; wherein, the model registration information carries the twin model name and its corresponding model capabilities, and the twin model library is located in a network element of the radio access network or core network.

[0076] For example, NFs send model registration information to CN-TNSSOF and RAN-TNSSOF. NF (Network Functions) are functional network elements deployed in RAN or CN, used to carry twin models. NFs represent multiple NFs. NFs deployed in RAN send model registration information to RAN-TNSSOF, and NFs deployed in CN send model registration information to CN-TNSSOF. At this time, CN-TNSSOF and RAN-TNSSOF receive and store the model registration information sent by any twin model library. The model registration information carries the twin model name (NF DTID) and its corresponding model capability (DT capability). The twin model library is the NF, located in the network elements of the radio access network RAN ​​or core network CN.

[0077] 2. Consumers send twin task requests to TSMF.

[0078] 3-4. TSMF receives twin task requests sent by consumers and parses the twin task requests to obtain twin service orchestration requirements. The twin task request carries the consumer's first quality of service requirements for the twin service; furthermore, the twin task request also carries the network scenario type, at which point the twin service management function is also used to parse the network element names and topology relationships involved in the twin task from the network scenario type.

[0079] For example, the twin service orchestration requirements include network element names, topology relationships, and a second quality of service requirement for the twin service chain. After receiving the twin task request from consumers, the TSMF is responsible for parsing the request. It extracts the network element names (NF names) and topology relationships involved in the twin task from the description of the Scene type field. For example, if the parsed network element name is a RAN NF name, it indicates that the twin model to be used is located in a RAN network element. Adding the network element name to the twin service orchestration requirements can improve the efficiency of subsequent twin model lookup. Then, the TSMF maps the first quality of service requirement of the twin task request to the second quality of service requirement of the twin service chain, such as the granularity, inference capability, and real-time performance of the twin model. The parsed twin service orchestration requirements are then sent to the TNSOF.

[0080] 5. After receiving the twin service orchestration request from TSMF, TNSOF determines whether the twin task involves a single domain or cross-domain operations. Each single-domain network element corresponds to a sub-service orchestration function.

[0081] For example, TNSOF determines the target domain by the network element name. If the twin service orchestration requirement only carries the RAN NF name or only carries the CN NF name, it means that the twin task only involves a single domain, that is, the target domain is a single domain. If the twin service orchestration requirement carries both the RAN NF name and the CN NF name, it means that the twin task involves cross-domain, that is, the target domain is a cross-domain.

[0082] 6a. When the network element name in the twin service orchestration request carries the RAN NF name, the TNSOF sends the twin service orchestration request to the RAN-TNSSOF in the TNSSOF.

[0083] 6b. When the network element name in the twin service orchestration request carries the CN NF name, the TNSOF sends the twin service orchestration request to the CN-TNSSOF in the TNSSOF.

[0084] 7. Upon receiving a twin service orchestration request, RAN-TNSSOF and / or CN-TNSSOF, since the twin service orchestration request carries the network element name, search for the corresponding target twin model among several registered twin models based on the network element name and the second quality of service requirement. Because RAN-TNSSOF and CN-TNSSOF can determine whether they need to perform a search operation based on the network element name, if so, they search for twin models that meet the second quality of service requirement of the twin service chain and record the twin model name (NF DTID) that meets the matching degree condition.

[0085] 8a-9a When RAN-TNSSOF finds the target twin model, it requests the target twin model from the corresponding twin model library and receives the target twin model returned by the twin model library. At this time, RAN-TNSSOF sends NF DTID to NFs in RAN, and NFs in RAN return the corresponding target twin model.

[0086] 8b-9b When CN-TNSSOF finds the target twin model, it requests the target twin model from the corresponding twin model library and receives the target twin model returned by the twin model library. At this time, CN-TNSSOF sends NF DTID to NFs in CN, and NFs in CN returns the corresponding target twin model.

[0087] Furthermore, depending on whether the target domain is single-domain or cross-domain, there are two arrangement methods:

[0088] Method 1: When the twin task involves a single-domain network element, that is, when the target domain is a single domain, the sub-service orchestration function corresponding to the single-domain network element is used to perform parallel orchestration of the target twin model corresponding to the twin task request according to the topology relationship.

[0089] For example, when the target domain is a single-domain network element, the sub-service orchestration function orchestrates the target twin model according to the topology relationship to generate a corresponding twin service chain. If the target domain is only CN, then referring to 10a and 11a, CN-TNSSOF orchestrates the target twin model according to the topology relationship to obtain a first twin service chain. The twin models in this service chain all originate from CN. The first twin service chain executes the twin service and returns the twin service result to the requester. If the target domain is only RAN, then referring to 10b and 11b, RAN-TNSSOF orchestrates the target twin model according to the topology relationship to obtain a second twin service chain. The twin models in this service chain all originate from RAN. The second twin service chain executes the twin service and returns the twin service result to the requester. If the twin service chain type TSST is a data generation service, then the target twin model is orchestrated according to the topology relationship corresponding to the twin service chain type, so that the orchestrated twin service chain can provide data generation services.

[0090] Method 2: When the twin task involves cross-domain network elements, that is, when the target domain is a cross-domain network element, the service orchestration function is used to request the target twin model from the corresponding sub-service orchestration function, and the target twin model corresponding to the twin task request is orchestrated in parallel according to the topology relationship.

[0091] For example, when the target domain is a cross-domain network element, each sub-service orchestration function sends the received target twin model to the service orchestration function. The service orchestration function orchestrates the target twin model according to the topology relationship to generate a corresponding twin service chain. If the target domain includes RAN and CN, referring to 12a-14, CN-TNSSOF and RAN-TNSSOF perform lookup operations respectively to obtain the corresponding target twin model, and then send the target twin model they received to TNSOF for aggregation. TNSOF orchestrates the target twin model according to the topology relationship to obtain a third twin service chain. The twin models in this service chain all originate from RAN and CN. The third twin service chain executes the twin service and returns the twin service result to the requester.

[0092] Compared to related technologies, the digital twin service orchestration method and system disclosed herein parses the twin task requests sent by the requesting party to obtain twin service orchestration requirements. Based on these requirements and the target twin model of the twin task, corresponding twin service chains are orchestrated and generated to provide twin services. Because corresponding twin service chains are generated according to different twin task requests, a parallel service mode is adopted. Twin service chains are dynamically orchestrated on demand according to different service requirements, providing precise and refined twin services. This eliminates the need to consume massive resources such as communication and computing power to build a network digital twin system. Furthermore, the digital twin network can guarantee the SLA (Service Level Agreement) requirements of different users and different twin services without wasting resources, and can simultaneously provide numerous services such as simulation verification, data generation, decision generation and pre-verification, as an interactive environment for AI training, and visualization.
