[0046] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0047] Referring to Figure 1 , Figure 1 is a flowchart of a digital twin service arrangement method provided by an embodiment of the application, the digital twin service arrangement method is implemented by a digital twin service arrangement execution, and the method comprises:

[0048] S1, receiving at least one twin task request sent by a demand side; wherein the twin task request carries a first service quality demand of the demand side for the twin service;

[0049] S2, mapping the first service quality requirement to a second service quality requirement for a twin service chain;

[0050] S3, finding a corresponding target twin model in a plurality of registered twin models according to the second service quality requirement;

[0051] S4, requesting the target twin model from a corresponding twin model library, and parallelly scheduling the target twin model corresponding to the twin task request to generate a parallel twin service chain.

[0052] For example, by analyzing the twin task request sent by the demander, the first service quality requirement is obtained, and the first service quality requirement is mapped to the second service quality requirement for the twin service chain, so as to request the target twin model corresponding to the twin task according to the second service quality requirement, and schedule to generate the corresponding twin service chain to provide the twin service. Since the corresponding twin service chain is generated according to different twin task requests, the parallel service mode is adopted, and the twin service chain is dynamically scheduled according to different service requirements to provide accurate and fine twin service, so that the huge resources such as communication and computing power are not occupied to construct the network digital twin system.

[0053] Referring to Figure 2 , Figure 2 is a structural block diagram of a digital twin service scheduling system provided by an embodiment of the application, the digital twin service scheduling system comprising a twin service management function, a service scheduling function and at least one sub-service scheduling function, wherein the steps S1-S2 are executed by the twin service management function, the step S3 is executed by the sub-service scheduling function, and the step S4 is executed by the service scheduling function or the sub-service scheduling function. The functions of each module are as follows:

[0054] The twin service management function, hereinafter referred to as TSMF (Twin Service Management Function), is used to receive the twin task request sent by the demander; wherein the twin task request carries the first service quality requirement of the demander for the twin service; and is also used to map the first service quality requirement to a second service quality requirement for a twin service chain;

[0055] The service scheduling function, hereinafter referred to as TNSOF (Twin Network Service Orchestration function), is used to receive the second service quality requirement sent by the twin service management function, determine the target domain that needs to execute the twin service, and send the second service quality requirement to the sub-service scheduling function corresponding to the target domain;

[0056] At least one sub-service orchestration function, hereinafter referred to as TNSSOF (Twin network subServiceOrchestration function), is configured to search for a corresponding target twin model from a plurality of registered twin models according to the second service quality requirement, and to perform parallel orchestration on the target twin model corresponding to the twin task request, thereby generating a parallel twin service chain.

[0057] For example, the main function of the TSMF is to analyze the QoS (Quality of Service) requirement of the twin task request and analyze the network element (i.e., the network element where the twin model is located) and the topology relationship involved in the twin task, convert the QoS requirement (the first service quality requirement) of the consumer into the QoS related requirement (the second service quality requirement) of the twin service chain, and then send it to the TNSOF.

[0058] For example, the main function of the TNSOF is to be responsible for the orchestration and management of the model, computing resources, and communication resources of the twin task. Specifically, it needs to include: 1) judging whether the target domain involved in the twin task is the RAN (Radio Access Network) domain or the CN (Core Network) domain; 2) distributing the twin task to the sub-service orchestration function corresponding to the RAN domain and the sub-service orchestration function corresponding to the CN domain; 3) if the twin task involves cross-domain (i.e., both RAN domain and CN domain), 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 properties, functions, and performance), the twin environment also needs to have protocol models, AI decision models, etc. The TNSOF is responsible for the construction, updating, and management of other twin models in addition to the network element twin model.

[0059] Exemplarily, it is assumed that there are two sub-service orchestration functions TNSSOF, i.e., a sub-service orchestration function corresponding to the RAN domain (referred to as RAN-TNSSOF) and a sub-service orchestration function corresponding to the CN domain (referred to as CN-TNSSOF). The main function of the RAN-TNSSOF is to be responsible for the twin service orchestration of the radio access network RAN (including model orchestration, computing resource orchestration and communication resource orchestration); it can request the twin from the related network element in the RAN according to the task demand issued by the TNSOF, and arrange according to the parsed scene topology relationship, and process the twin task based on the arranged twin service chain. The main function of the CN-TNSSOF is to be responsible for the twin service orchestration of the core network CN (including model orchestration, computing resource orchestration and communication resource orchestration); it can request the twin from the related network element in the CN according to the task demand issued by the TNSOF, and arrange according to the parsed scene topology relationship, and process the twin task based on the arranged twin service chain.

[0060] Further, new DT (Digital Twin) network elements are added in the RAN and the CN, and the RAN and the CN have the twin DT model in addition to the network element entity, which can be updated in real time according to the physical network data.

[0061] Specifically, there are two ways for the deployment of each function in the digital twin service orchestration system, one is centralized deployment, and the other is separate deployment.

[0062] In the first implementation, the twin service management function TSMF and the service orchestration function TNSOF are both deployed in the operation administration and maintenance system (OAM), one of the sub-service orchestration functions is deployed in the base station, such as the RAN-TNSSOF deployed in the gNB, and the other sub-service orchestration function is deployed in the core network, such as the CN-TNSSOF deployed in the CN as a network element in the CN.

[0063] 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 administration and maintenance system (OAM).

[0064] Further, taking the example that there are two sub-service orchestration functions in the digital twin service orchestration system, there are a first interface, a second interface and two third interfaces between each function module in the digital twin service orchestration system, and the number of the third interfaces corresponds to the number of the sub-service orchestration functions. The data transmitted by the four interfaces is as follows:

[0065] 1) The first interface is the interface between the TSMF and the outside (such as a consumer), which is mainly used to transmit a twin task request carrying the following information: {Scene type, TSST=N, DQTI}.

[0066] 1.1) Scene type represents the network scene type, and different task requests have corresponding network scene types, such as a face recognition scene, a data collaboration scene, a video conference scene, etc.

[0067] 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 a data generation service, TSST=2 represents a policy pre-validation service, and TSST=3 represents a visualization service.

[0068] 1.3) DQTI (Digital Twin QoS Identifier) represents the first service quality requirement of the demand side for the twin service, which is determined based on the twin service chain type. For each TSST, DQTI has certain differences. For example, for TSST=1, at least includes {Data accuracy, generation delay, data volume}; for TSST=2, at least includes {validation accuracy, validation delay}; for TSST=3, at least includes {Visual type: {2D, 3D}, distinguishability, interaction, rendering speed}.

[0069] 2) The second interface is the interface between the twin service management function TSMF and the service orchestration function TNSOF, which is mainly used to transmit the parsed twin service orchestration requirement, including the network element name (NF name), the topology relationship (topology relation), and the second service quality requirement of the twin service chain. The network element name represents the name of the network element involved in the network scene, the topology relationship represents the topology relationship between the twin models, and the second service quality requirement of the twin service chain is related to the twin service chain type TSST in the twin task request. For example, when TSST=1, the first service quality requirement is data accuracy, generation delay, and data volume, and the second service quality requirement of the twin service chain can be the fineness of the twin model, the inference ability, the real-time performance, etc.

[0070] 3) the third interface 1 is used for transmitting messages between the TNSOF and the RAN-TNSOF, and the RAN-TNSOF transmits messages to the RAN, including at least a RAN network element name (RAN NF name) and a topology relation. The RAN transmits model registration information to the RAN-TNSOF.

[0071] 4) the third interface 2 is used for transmitting messages between the TNSOF and the CN-TNSOF, and the CN-TNSOF transmits messages to the CN, including at least a CN network element name (CN NF name) and a topology relation. The CN transmits model registration information to the CN-TNSOF.

[0072] For example, referring to Figure 3 , Figure 3 is another flowchart of a digital twin service orchestration method provided by an embodiment of the application, to Figure 3 The steps shown in FIG. 1 are used to describe the working processes of various modules in the digital twin service orchestration system in detail, including steps 1-14.

[0073] 1a-1b, any of the sub-service orchestration functions is further configured to receive and store model registration information sent by a corresponding twin model library; wherein the model registration information carries a twin model name and its corresponding model capability, and the twin model library is located in a network element of a radio access network or a core network.

[0074] For example, the NFs send model registration information to the CN-TNSOF and the RAN-TNSOF. NF (Network Functions) is a functional network element deployed in the RAN or the CN, used to carry a twin model. NFs represent multiple NFs. The NFs deployed in the RAN send model registration information to the RAN-TNSOF, and the NFs deployed in the CN send model registration information to the CN-TNSOF. At this time, the CN-TNSOF and the RAN-TNSOF receive and store model registration information sent by any twin model library; wherein the model registration information carries a twin model name (NF DTID) and its corresponding model capability (DTcapability), and the twin model library, i.e., the NF, is located in a network element of a radio access network RAN or a core network CN.

[0075] 2, the demand side consumers send a twin task request to the TSMF.

[0076] 3~4, the TSMF receives a twin task request sent by a consumer, and parses the twin task request to obtain a twin service orchestration requirement. The twin task request carries a first service quality requirement of the twin service by the consumer; further, the twin task request also carries a network scene type, and at this time the twin service management function is further configured to parse a network element name and a topology relation involved in the twin task from the network scene type.

[0077] For example, the twin service orchestration requirement includes the network element name, the topology relation and a second service quality requirement of the twin service chain. After receiving the twin task request sent by the consumer, the TSMF is responsible for parsing the twin task request, and parses the network element name (NF name) and the topology relation involved in the twin task from the description of the network scene type (Scene type) field, such as parsing the network element name as RAN NF name, indicating that the twin model to be used is located in the RAN network element. Adding the network element name in the twin service orchestration requirement can improve the efficiency of subsequent twin model searching. Then, the TSMF maps the first service quality requirement of the twin task request to the second service quality requirement of the twin service chain, such as the second service quality requirement being the fineness, inference ability and real-time performance of the twin model. The parsed twin service orchestration requirement is sent to the TNSOF.

[0078] 5, after the TNSOF receives the twin service orchestration requirement of the TSMF, it is judged whether the twin task involves a single domain or a cross-domain, wherein each single domain network element corresponds to a sub-service orchestration function.

[0079] For example, the TNSOF judges 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 indicates 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 indicates that the twin task involves a cross-domain, that is, the target domain is a cross-domain.

[0080] 6a, when the network element name in the twin service orchestration requirement carries the RAN NF name, the TNSOF sends the twin service orchestration requirement to the RAN-TNSSOF in the TNSSOF.

[0081] 6b, when the network element name in the twin service orchestration requirement carries the CN NF name, the TNSOF sends the twin service orchestration requirement to the CN-TNSSOF in the TNSSOF.

[0082] 7、RAN-TNSSOF and / or CN-TNSSOF, after receiving the twin service orchestration requirement, since the twin service orchestration requirement carries the network element name, at this time, according to the network element name and the second quality of service requirement, the corresponding target twin model is searched in the registered several twin models. Since according to the network element name, RAN-TNSSOF and CN-TNSSOF can know whether it needs to perform the search operation, if it needs to perform the search operation, the twin model that meets the second quality of service requirement of the twin service chain is searched, and the twin model name (NF DTID) that meets the matching degree condition is recorded.

[0083] 8a~9a, when RAN-TNSSOF queries the target twin model, the target twin model is requested from the corresponding twin model library, and the target twin model returned by the twin model library is received, at this time, RAN-TNSSOF sends NF DTID to NFs in RAN, and NFs in RAN return the corresponding target twin model.

[0084] 8b~9b, when CN-TNSSOF queries the target twin model, the target twin model is requested from the corresponding twin model library, and the target twin model returned by the twin model library is received, at this time, CN-TNSSOF sends NF DTID to NFs in CN, and NFs in CN return the corresponding target twin model.

[0085] Further, according to whether the target domain is single domain or cross domain, there are two kinds of orchestration modes:

[0086] Mode 1, when the twin task involves single domain network element, that is, the target domain is single domain, the corresponding sub-service orchestration function of the single domain network element is used to perform parallel orchestration on the target twin model corresponding to the twin task request according to the topological relationship.

[0087] Exemplarily, 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, referring to 10a and 11a, the CN-TNSSOF orchestrates the target twin model according to the topology relationship to obtain a first twin service chain, and the twin models in the service chain are all derived from CN, the first twin service chain executes the twin service and returns the twin service result to the demander. If the target domain is only RAN, referring to 10b and 11b, the RAN-TNSSOF orchestrates the target twin model according to the topology relationship to obtain a second twin service chain, and the twin models in the service chain are all derived from RAN, the second twin service chain executes the twin service and returns the twin service result to the demander. Thus, when the twin service chain type TSST is a data generation service, 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 the data generation service.

[0088] Mode 2, when the twin task involves cross-domain network elements, that is, the target domain is a cross-domain network element, the service orchestration function requests the target twin model from the corresponding sub-service orchestration function, and orchestrates the target twin model corresponding to the twin task request in parallel according to the topology relationship.

[0089] Exemplarily, 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, and 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, the CN-TNSSOF and the RAN-TNSSOF perform the lookup operation respectively to obtain the corresponding target twin model, and then send the target twin model received by themselves to the TNSOF, and the TNSOF orchestrates the target twin model according to the topology relationship to obtain a third twin service chain, and the twin models in the service chain are all derived from RAN and CN, the third twin service chain executes the twin service and returns the twin service result to the demander.

[0090] Compared with the prior art, the digital twin service arrangement method and system disclosed by the application can obtain a twin service arrangement requirement by analyzing a twin task request sent by a demand side, can generate a corresponding twin service chain according to a target twin model that meets the twin service arrangement requirement, and can provide a twin service. Since the corresponding twin service chain is generated according to different twin task requests, a parallel service mode is adopted, the twin service chain is dynamically arranged on demand according to different service requirements, and accurate and refined twin services are provided, so that a network digital twin system does not need to occupy huge resources such as communication and computing power to be constructed. In addition, the digital twin network can guarantee the SLA (Service Level Agreement) requirement of different users for different twin services, does not cause waste of resources, and can simultaneously and in parallel provide services such as simulation verification, data generation, decision generation and pre-verification, an interactive environment for AI training, visualization and the like.

The processor 11 realizes various functions of the digital twin service orchestration device 100 by running or executing computer programs and / or modules stored in the memory 12, and calling data stored in the memory 12. The memory 12 can mainly include a program storage area and a data storage area.
