[0122] It should be understood that in this application, "sending information to...(terminal)" can be understood as the destination of the information being the terminal. It can include sending information to the terminal directly or indirectly. "Receiving information from...(terminal)" can be understood as the source of the information being the terminal, which can include receiving information from the terminal directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0123] In order to facilitate understanding of the embodiments of the present application, first, a brief introduction is given to the concepts and technologies involved in the embodiments of the application.

[0124] It should be understood that the related terms and explanations in the following text are common to all embodiments throughout the text, and different embodiments can be used independently or in combination based on certain internal or external connections, and different implementation methods in the embodiments can be used independently or in combination.

[0125] 1. Physical network layer

[0126] The physical network layer mainly includes all physical entities that constitute the end-to-end network. Various network elements in the network exchange network data and network control information with the network twin through the twin southbound interface. As an entity object of the network twin, the physical network can be a mobile access network, a mobile core network, a data center network, a campus enterprise network, an industrial Internet of Things and other network types; it can be a subnet of a single network domain (for example, access network, transmission network, core network, bearer network, etc.) or an end-to-end cross-domain network.

[0127] A physical entity is the physical object itself. For hardware, it is the hardware form itself, such as the base station board, antenna, chip, etc. For software, it is the carrier of the software, such as image files, various forms of software code, etc.

[0128] 2. Digital Twin

[0129] A digital twin is a digital object that is a twin of a physical object (a digital twin management model). For example, a network element is twinned to generate a digital twin of the network element, and a network is twinned to generate a digital twin of the network. In a digital twin network, the digital twin is synchronized with the state of the physical entity. The digital twin management model includes: attributes, states, time series data, and behaviors.

[0130] 3. Simulation body

[0131] A simulation body refers to the simulation of the physical entity corresponding to the digital twin through digital technology, which can achieve the purpose of visualization.

[0132] like Figure 1 As shown, the management of communication networks currently mainly involves the upper-layer network management system (operation support systems, OSS) of operators and the equipment management system (vendor domain management system) designed by equipment manufacturers for their own manufacturers. The interaction between the operator network management system OSS and the vendor domain management system adopts standardized interfaces (such as the management interface for network elements / networks defined by 3GPP SA5, involving network element / network performance management (PM) interface, fault management interface (FM), configuration management interface (CM), etc.). Since the internal implementation of network element devices (such as network element devices) of various manufacturers does not need to be standardized, and the implementation differences of various manufacturers are also large, the current vendor domain management system and the equipment use the manufacturer's private implementation interface. Taking configuration management as an example, standard network element / network configurable parameters are defined between OSS and the vendor domain management system. These parameters are the basis for the normal operation of the network. All manufacturers support the configuration of standard parameters. However, due to the different internal implementations of the equipment, the private interface between the vendor domain management system and the equipment will contain more private parameter configurations, which are different for each manufacturer.

[0133] In one possible implementation method, in the possible digital twin implementation architecture proposed by the operator, a digital twin is built in the operator's OSS domain, and the construction of the digital twin is achieved by standardizing the information transmitted on the interface between more vendor domain management systems and OSS.

[0134] It should be understood that the key to building a digital twin is to construct an accurate digital mapping of the physical object. Currently, the operator's OSS domain only obtains part of the parameters, performance and fault indicators of the network element / network operation through the standard interface. The internal operation information of the equipment is only maintained and managed in the manufacturer's domain management system. This part of the content is difficult to standardize, and even if it is standardized, it will take a long time, which is not conducive to the promotion of digital twin technology.

[0135] Another key technology for building digital twins is the simulation of devices (including network elements / networks). Currently, the internal implementation of devices is not within the scope of standards. Even if OSS obtains all the parameter information of the device (standardized parameters and private management parameters), it is still difficult to simulate the device because the internal implementation of the device is unknown. Therefore, the digital twins currently built in the OSS domain cannot truly reflect the operation of the physical network. They can only view the operation of the physical network based on standardized data, but cannot provide high-level services (such as disaster recovery switching verification based on digital twins, prediction of network configuration results, etc.).

[0136] Based on the above problems, this application provides a management method based on digital twin services.

[0137] like Figure 2 As shown, two new services, digital twin service and simulation service, are added to the manufacturer domain management system. The digital twin service is used to obtain physical entity data and operate physical entities. The digital twin service includes a digital twin service provider and a digital twin management service. The simulation service corresponds to the digital twin service and is used to display physical entity data in real time.

[0138] like Figure 3 As shown, the management model of the digital twin service includes digital twin service objects, digital twin objects and simulation objects.

[0139] The digital twin service object (DigitalTwin) may contain the following parameters as shown in Table 1:

[0140] Table 1. Parameters and parameter contents included in digital twin services

[0141]

[0142]

[0143] The digital twin object (DigitalTwinEntity) represents that a digital twin service instance may need to create one or more digital twin instances during the creation process. The parameters that the digital twin object may contain are shown in Table 2:

[0144] Table 2. Parameters and parameter contents included in the digital twin

[0145]

[0146] EmulationObject object. When the digital twin service has visualization requirements, the digital twin service will call the simulation service and request to create the corresponding emulation object instance. The emulation object may contain the following parameters: address, the access address information of the emulation, which can be in the form of URI or IP address.

[0147] like Figure 4 As shown, a dotted line or a dotted line box indicates that the step is a step that can be performed in some implementations, and a solid line or a solid line box indicates that the step is a necessary step. The method 100 may include the following steps:

[0148] S110, the second device sends the first information, and correspondingly, the first device receives the first information.

[0149] The second device is an operator device, which is a service consumer and the provider of digital twin services. It can be an operator's management system or a system used to manage other manufacturers' domain management systems. This application does not limit this.

[0150] The first device is used to manage physical entities. The first device can be a manufacturer device that manages physical entities. The first device includes digital twin services and simulation services. The digital twin services include digital twin service providers and digital twin management services. The digital twin service provider, digital twin management service, and simulation service can be located separately on multiple devices or concentrated in one device. They are all devices in the manufacturer domain management system and are used to directly manage physical entities, networks, and networks. Due to the different internal implementations of each manufacturer's equipment, the private interface between the manufacturer domain management system and the device will contain more private parameter configurations, that is, the first device can obtain the internal operation information of the physical entity. In the following description, the digital twin service provider, digital twin management service, and simulation service are described separately, which can be understood as the description of the first device.

[0151] The second device sends the first information, and the first information is used to indicate the creation of the digital twin requested by the second device. The first information is used to request the creation of at least one twin service DigitalTwin instance. The first information includes at least one of the following parameters: target, scope, information requirements, capability information, supported operation information, operation information, digital twin instance information and simulation instance information; wherein, the target parameter is used to indicate the physical entity corresponding to the digital twin instance, the scope parameter is used to indicate the service scope of the digital twin instance, the information requirement parameter is used to indicate the physical entity data required by the digital twin instance, the capability information parameter is used to indicate the capabilities of the digital twin instance, the supported operation information indicates the capabilities of the digital twin instance, and the operation information indicates the operation requirements of the second device.

[0152] Exemplarily, the first information may carry a DigitalTwin object, including:

[0153] Target parameter (target): network identification (target network information, i.e., the identification of the physical entity, or the area information where the physical entity is located, which can be used to select a suitable physical entity network);

[0154] Scope parameter: disaster recovery switchover;

[0155] Information requirement parameters (requirements): network element signaling, alarm information;

[0156] Capability information parameters (capabilities): visibility, verification (the created digital twin instance has visibility and verifiability).

[0157] In a possible implementation, the digital twin service provider receives the first information from the second device through a first interface. The first interface is a digital twin service interface, which is located between the first device and the second device.

[0158] In another possible implementation, the digital twin service provider receives first information sent by the second device through an intent interface, where the first information is intent information created by the second device.

[0159] S120: The digital twin service provider determines at least one digital twin instance that needs to be created.

[0160] The digital twin service provider determines at least one digital twin instance based on the first request information, and the digital twin instance is associated with corresponding physical entity data.

[0161] The digital twin service can include multiple digital twins that have been created. Depending on different requirements, there may be multiple digital twins corresponding to the same physical entity. For example, for the same network element, there may be a digital twin that only targets signaling transmission on the network element and a digital twin that only targets alarm information. There may also be a digital twin that simulates both signaling transmission and alarm information on the network element. A digital twin can be a digital model that is a twin of a physical network element / network.

[0162] S130, the digital twin service provider sends a first request message, and correspondingly, the digital twin management service receives the first request message.

[0163] The first request information is used to request the creation of at least one digital twin instance that needs to be created.

[0164] S140, the digital twin management service creates at least one digital twin instance.

[0165] Exemplarily, multiple digital twin instances may be created according to the first request information:

[0166] Create DigitalTwinEntity-1, which contains the following parameters:

[0167] Scope: Signaling (this digital twin instance mainly twins and models the signaling in the network);

[0168] networkRef: network-1 (primary network ID);

[0169] capability: verification (capability to verify);

[0170] Configurable parameters: capacity (weight information), taiList (service location information), plmnInfo (operator slice information), etc.

[0171] Create digital twin object instance 2 (DigitalTwinEntity-2). Digital twin instance 2 specifically contains the following parameters:

[0172] Scope: alarm information (this digital twin instance mainly twins and models the alarm information in the network);

[0173] networkRef: network-1 (primary network ID);

[0174] capability: verification (capability to verify).

[0175] Create digital twin object instance 3 (DigitalTwinEntity-3), which specifically includes the following parameters:

[0176] Scope: Signaling (this digital twin instance mainly twins and models the signaling in the network);

[0177] networkRef: network-2 (backup network identifier);

[0178] capability: verification (capability to verify);

[0179] Configurable parameters: capacity (weight information), taiList (service location information), plmnInfo (operator slice information), etc.

[0180] Create digital twin object instance 4 (DigitalTwinEntity-4), which specifically includes the following parameters:

[0181] Scope: alarm information (this digital twin instance mainly twins and models the alarm information in the network);

[0182] networkRef: network-2 (backup network identifier);

[0183] capability: verification (capability to verify).

[0184] S141, the digital twin management service sends a first reply message, and correspondingly, the digital twin service provider receives the first reply message.

[0185] The first reply information includes information of the digital twin instance.

[0186] S150, the digital twin service provider sends a second request message, and correspondingly, the simulation service receives the second request message.

[0187] The simulation service is used to simulate the generated digital twin (can be one or more) and generate a simulation body, which is mainly used for observation. Through data synchronization between network entity objects and digital twins, data changes can also be observed in real time on the simulation body. The simulation service can send the created simulation body to the operator management system in the form of real-time data stream to meet the operator's observation needs.

[0188] The digital twin service corresponds to the simulation service. The simulation service is used to display physical entity data in real time. When the first information indicates that the digital twin instance capability information parameters include visual (capabilities) capabilities, the digital twin service provider sends a second request information. The second request information includes information about the successfully created digital twin instance. The second request information is used to instruct the simulation service to create at least one simulation instance. The simulation instance corresponds to the digital twin instance.

[0189] S160, the simulation service creates a simulation body.

[0190] S161, the simulation service sends a second reply message, and correspondingly, the digital twin service provider receives the second reply message.

[0191] The simulation service creates a digital twin simulation instance based on at least one digital twin object instance information in the received second request information, and responds with a successful response (i.e., the second reply information) if the simulation is successfully created. The response includes the access information of the simulation (URL or IP address information for connection, etc.).

[0192] S170, the digital twin service provider sends the second information, and correspondingly, the second device receives the second information.

[0193] The second information is used to indicate the operations that can be performed on the digital twin instance.

[0194] The second information includes information of at least one digital twin instance and access information of at least one simulation instance.

[0195] The second information is used to reply to the digital twin service object instance creation success response, which includes the digital twin service object instance information. The access information is used to request a real-time data stream from at least one simulation instance.

[0196] Exemplarily, it may include the operations (SupportedOperation) supported by the digital twin service instance and access information of the simulation body, etc. The supported operations may be switching verification or switching execution or switching verification and execution.

[0197] S180: The second device requests a real-time data stream.

[0198] S190, the simulation service sends a real-time data stream, and correspondingly, the second device receives the real-time data stream.

[0199] The second device uses the received access information of the simulation body to request the simulation body real-time animation. The simulation body service sends the real-time data stream to the second device through the second interface, and the simulation service returns the simulation real-time animation to the service consumer.

[0200] Exemplarily, the simulation service may establish a data stream transmission channel, ie, a second interface, between the simulation entity and the consumer based on a real-time data stream transmission method.

[0201] like Figure 5 As shown, the present application provides a management method 200 based on digital twin services.

[0202] The method comprises at least the following steps:

[0203] S210, the second device sends the third information, and accordingly, the digital twin service provider receives the third information.

[0204] At least one digital twin instance created by the digital twin service includes a first instance and a second instance, the first instance corresponds to a first physical entity, the first physical entity is used to run a primary network service, and the second instance corresponds to a second physical entity, the second physical entity is used to run a backup network service.

[0205] The third information indicates that a first operation is performed on the digital twin instance. The third information is used to indicate a requirement for the first operation of the second device. The first operation includes updating parameters of the first instance and the second instance.

[0206] According to the supported operation information contained in the digital twin service instance information, a request to execute the operation is sent to the digital twin service provider. Exemplarily, in step S170 of method 100, the digital twin service instance received by the service consumer may contain supported operation parameters, including:

[0207] Name: Operation name.

[0208] The third information indicates to update the digital twin service instance and set the Operation parameters.

[0209] For example, the parameters may include the following information:

[0210] Name: Switchover verification (operation name, from SupportedOperation);

[0211] Operationtarget: Operation target (the target of the operation execution, for example, in this example, the target can be that the user switches from the primary network to the backup network and re-registers within 20 minutes during the switchover process)

[0212] In a possible implementation, the digital twin service provider receives the third information from the second device through a first interface. The first interface is a digital twin service interface, which is located between the first device and the second device.

[0213] In another possible implementation, the digital twin service provider receives third information sent by the second device through the intent interface, where the third information is intent information created by the second device.

[0214] Exemplarily, the intent information may be:

[0215] “Intent:

[0216] userLabel:1#Any value

[0217] intentExpectation:

[0218] expectationId:1#arbitrary value

[0219] expectationObject:

[0220] objectInstance:DigitalTwin-1#Digital Twin service object instance identifier

[0221] expectationTargets:

[0222] -targetName:"Operation"

[0223] targetCondition: "is equal to"

[0224] targetValueRange: "Switch verification" #Values ​​from SupportedOperation

[0225] -targetName:"ReRegistrationTime"

[0226] targetCondition:"IS_LESS_THAN"

[0227] targetValueRange:"20"#Unit: minutes"

[0228] Wherein objectInstance represents the object information targeted by the intent, and in the above implementation, its value is the created digital twin service instance identifier, which may be from the creation in method 100 and is generally provided by the service consumer's second device in the first step.

[0229] ExpectationTargets is used to indicate the target of the intent. The above example contains two targets. One is that the target of the operation to be performed is switchover verification, and the other is that the ReRegistrationTime is less than 20 minutes.

[0230] S220, the digital twin service provider generates a first solution.

[0231] S221, the digital twin service sends a first solution, and correspondingly, the digital twin management service receives the first solution.

[0232] The digital twin service provider determines the first solution based on the third information.

[0233] S230, the digital twin service provider sends a first response message to the second device.

[0234] The digital twin service provider replies with a response that the first operation is accepted and is waiting for simulation update content.

[0235] S240, the digital twin management service performs a first operation.

[0236] After receiving the first solution, the digital twin management service performs a first operation on the digital twin instance according to the first solution, and the first operation includes updating parameters of the first instance and the second instance.

[0237] Exemplarily, the digital twin service provider generates a switching plan based on the received request and sends a set of new configuration parameters to at least one digital twin instance, such as setting the value of capacity in configurable parameters in DigitalTwinEntity-1 to 0, and setting the value of capacity in configurable parameters in DigitalTwinEntity-3 to 100. This means that the weight of the digital twin of the primary network is 0 and is in an unavailable state; the weight of the digital twin of the backup network is 100 and is in an available state, thus achieving the switching of the primary and backup networks.

[0238] The first operation may further include operating the first physical entity and the second physical entity according to updated parameters of the first instance and the second instance, so that the primary network switches to the backup network.

[0239] It should be understood that the supported operation names can be switching verification, switching execution, switching verification and execution. Among them, switching verification is only a switching verification on the digital twin service instance, and does not affect the real physical network; switching execution refers to directly performing a switching operation on the digital twin service instance, and synchronously performing the same operation on the physical network; switching verification and execution means first performing a switching verification on the digital twin service instance, and when the verification switching plan meets the requirements, performing the same operation on the physical network.

[0240] S241, the digital twin management service replies with a second response message.

[0241] The digital twin management service sends a second response message, and the second response information is used to indicate that the first operation is successful.

[0242] S250, the simulation service updates the simulation content.

[0243] When the parameters of the digital twin instance are updated, the simulation service updates the real-time data stream generated by the simulation instance; since the information of the simulation instance and the digital twin instance is collected synchronously, the content of the simulation instance will also be updated in real time.

[0244] S260, the simulation service sends the updated real-time data stream.

[0245] According to the real-time data stream transmission channel created in S180 and S190 in method 100 , the updated simulated real-time data stream is sent.

[0246] S270, the digital twin service provider monitors and counts digital twin instances.

[0247] S280, the digital twin service provider sends a first operation report, and accordingly, the second device receives the first operation report.

[0248] The digital twin service provider monitors and compiles statistics on the operation data of the digital twin instance, such as the signaling statistics information for DigitalTwinEntity-1 and the alarm information for DigitalTwinEntity-2, and compares the statistics information with the indicators contained in the Operationtarget in the third information.

[0249] The first operation report is determined based on the operating data of the digital twin instance and the third information.

[0250] The first operation report also includes recommended operation information.

[0251] Exemplarily, the first operation report may be a switching verification report, which mainly includes information on whether the Operation target is achieved. If not achieved, it may include a recommended Operation target or other recommended information, such as starting the switching at 0 o'clock.

[0252] Exemplarily, if the Operation parameter in the third information carries the name information "switching verification and execution", and the first operation report meets the target set in the third information, the same operation is initiated to the physical network according to the switching plan generated in step S220, that is, the corresponding physical network initiates the distribution of new configuration information.

[0253] In another possible implementation, the first operation report may be included in an intent report (IntentReport), indicating whether each target included in expectationTargets is achieved. The intent report may also include suggestion information when the target is not achieved.

[0254] S290, the second device sends the fourth information, and accordingly, the digital twin service provider receives the fourth information.

[0255] S2100, the digital twin service provider generates a second solution.

[0256] A second solution is sent to the digital twin management service, where the second solution is determined based on the fourth information.

[0257] When the first operation report indicates that the operation data of the digital twin instance does not meet the parameters included in the first operation information, the first operation report also includes recommended operation information; the second device can determine fourth information based on the recommended operation information and send the fourth information. The first device performs a second operation on at least one digital twin instance based on the fourth information.

[0258] Exemplarily, if the first operation report shows that the switching target is achieved, the service consumer determines whether to perform other operations. If the first operation report shows that the switching target is achieved, and the switching verification report contains recommendation information, the service consumer determines whether to perform the recommended operation according to the recommendation information, such as resending the operation information and modifying the Operationtarget to the recommended value, that is, performing the second operation.

[0259] In another possible implementation, if the intent target is not achieved, a new intent request is sent to update the included intent content, such as updating the Operationtarget information.

[0260] According to the solution of this application, the digital twin is constructed by the manufacturer domain management system, and digital twin services are provided to the operator OSS domain, making the construction of the digital twin more accurate. At the same time, the operator OSS also gains the experience of digital twin services through the services provided by the manufacturer domain, achieving the goal envisioned by the operator in building a digital twin.

[0261] like Figure 6 As shown, the present application provides a management method 500 based on digital twin services.

[0262] In the following embodiments, the first device may be a management data analysis (MDA) functional entity, and through method 500 , a digital twin visualization and verification solution may be implemented based on the MDA functional entity.

[0263] According to the definition of management data analytics service (MDAS) in the protocol 3GPP TS28.104, the management function (MDAF) providing MDAS service can process and analyze data related to the network and services, such as analyzing network performance measures (PM), key performance indicators (KPI), technical service quality indicators (QoE) reports, alarms, configuration data, network analysis data and service experience data to provide useful analysis outputs, such as predicting faults; analyzing network energy consumption and providing recommended energy-saving solutions; analyzing network latency issues and providing the root causes of excessive latency in the network and recommended solutions to solve high latency, etc. MDA can also identify problems that affect network and service performance and help identify potential problems that may lead to potential failures and / or performance degradation in advance.

[0264] MDAF has the ability to obtain network information and analyze the network based on the information obtained. MDAF can provide the functions of digital twin service provider, digital twin management service and simulation service mentioned above.

[0265] The method 500 may include the following steps:

[0266] S510, the second device sends the fifth information, and correspondingly, the MDAF receives the fifth information.

[0267] The second device is an operator device and belongs to a service consumer. An MDARequest creation request, i.e., the fifth information, is sent to the first device MDAF. The fifth information is used to instruct the creation of a digital twin object.

[0268] The fifth information includes at least one of the following information: requirement information, output information, capability information parameters, scope information and time information; wherein, the requirement information is used to indicate MDAF to output analysis results and / or proposed solutions, the output information is used to indicate the manner in which MDAF outputs analysis results and / or proposed solutions, the capability information parameters are used to indicate the capabilities of the digital twin object, the scope information is used to indicate the analyzed network objects, and the time information is used to indicate the time range for the analysis.

[0269] Exemplarily, the fifth information carries an MDARequest object, which is defined in the 3GPP TS28.104 specification. The specific information is shown in the following Table 3:

[0270] Table 3, MDARequest object information

[0271]

[0272] The OutPutDTReq and ndtRef parameters are used to carry the service consumer's demand for digital twin output and to feedback the digital twin object information to the service consumer after MDAF completes the creation of the digital twin object.

[0273] S520, MDAF collects information.

[0274] MDAF is used to obtain information about network objects and to manage and analyze the information about network objects.

[0275] MDAF collects relevant network information based on the received MDARequest request.

[0276] Exemplarily, the specific network object to be analyzed (such as determining the network elements to be included in the analysis) is determined according to the analysis scope analyticsScope information in the MDARequest object. The collected information may include performance KPI information, alarm information, and configuration information of the analysis object (such as the network element). For example, for an AMF network element, the collected information may be information on the number of user registrations, the number of requests initiated by users, and the number of handover requests initiated by users.

[0277] S530, MDAF creates a digital twin instance;

[0278] S531, MDAF sends sixth information, and correspondingly, the second device receives the sixth information.

[0279] MDAF creates at least one digital twin object based on the fifth information and the information of the network object, that is, MDAF creates a digital twin instance based on the network information collected in the above step S520 and in combination with the digital twin requirement information in the MDARequest object. The digital twin object is associated with the physical network instance ID and capability information.

[0280] Exemplarily, in S510, the MDARequest carries the OutPutDTReq parameter, indicating that the output has a digital twin requirement and contains visual and verifiable features. Specifically, MDAF can include digital twin management functions, simulation functions, and create digital twin objects based on collected network information. For example, the analysis object (physical network object) contains an AMF network element, and the information contained in the network element object refers to the definition of the AMFFunction object in the standard 3GPP TS28.541.

[0281] MDAF generates a digital twin object based on the physical network object (for example, through information synchronization, simulation, etc.), which is also an AMFFunction object. In order to distinguish the digital twin object from the real physical network object, the digitalTwinData parameter can be added to the standard AMFFunction object. In the standard definition, AMFFunction and all 5G core network elements are inherited from the ManagedFunction object defined in the TS28.622 protocol. The digitalTwinData parameter can also be added to the ManagedFunction object, so that any network element can inherit the parameter from the ManagedFunction object. Specifically, the ManagedFunctioninformation objectclass can include the following attributes: vnfParametersList (this attribute exists when the ManagedFunction instance is implemented by one or more VNFs, otherwise the attribute does not exist), peeParametersList (indicating whether control and monitoring of PEE parameters are supported), priorityLabel (priority label), supportedPerfMetricGroups, supportedTraceMetrics, and digitalTwinData, etc. The parameters of digitalTwinData are shown in Table 4 below:

[0282] Table 4. digitalTwinData parameters

[0283]

[0284] Exemplarily, the generated digital twin object (object identifier AMF_DT_1) information includes the following as shown in Table 5: AMFFunction:

[0285] Table 5. AMFFunction parameters

[0286]

[0287] MDAF sends sixth information to the second device, the sixth information including at least one parameter of the digital twin object, and the sixth information is used to indicate an operation that can be performed on the digital twin object. MDAF sends the successfully created digital twin object to the second device.

[0288] S540, the MDAF sends a real-time data stream, and correspondingly, the second device receives the real-time data stream.

[0289] Optionally, S541, MDAF sends seventh information, and the seventh information is used to request establishment of a real-time data stream, and the real-time data stream is used to transmit a digital twin image generated based on at least one digital twin object, and the digital twin image includes information of the network object.

[0290] According to the visual requirements included in the MDARequest of the fifth message in step S510, MDAF requests the second device to establish a real-time data stream for transmitting the simulation-based digital twin image information.

[0291] Specifically, the establishStreamingConnection operation defined in 3GPP TS28.532 can be adopted, and the description of the digital twin information can be added to the streamInfoList.

[0292] For example, the following information may be included:

[0293] StreamType: DT (indicates that the data stream is used to transmit digital twin images).

[0294] objectID: AMF_DT_1 (indicating the digital twin object corresponding to the data stream).

[0295] content: PM KPI, alarm (optional, indicating the content contained in the transmitted digital twin image, such as KPI indicator change request, real-time alarm information, etc.)

[0296] Once the data stream is established, MDAF can send the image information of the created digital twin object to the second device.

[0297] S550, the MDAF sends a report, and correspondingly, the second device receives the report.

[0298] The report includes analysis results and / or recommended solutions. The analysis results are determined based on the data information of the network object and the fifth information. The recommended solution includes the third operation on the network object recommended by MDAF. The third operation includes modifying the parameters of the network object corresponding to the digital twin object.

[0299] MDAF outputs the analysis results, which are included in the report MDAReport object. The request includes a suggested solution to the problem (such as the parameter information that is recommended to be modified). For example, the MDARequest in S510 can be a request to analyze the feasibility of disaster recovery switching. MDAF analyzes how to switch the AMF network element to minimize the impact on the business, and the switching plan is included in the MDAReport. The recommended switching plan, for example, requires configuration updates to the AMF (such as reducing capacity, indicating that the processing of new user requests should be reduced).

[0300] Optionally, the method 500 may include: S560, the second device sends the eighth information to the digital twin object, and accordingly, the digital twin object receives the eighth information.

[0301] When the sixth information indicates that the digital twin object has the verification capability, the digital twin object can receive the eighth information sent by the second device, and the eighth information includes the identification ID information of the digital twin object. The ID information is used to indicate the target digital twin object to be sent.

[0302] The eighth information is determined according to the proposed solution, and the eighth information is used to indicate a fourth operation on the digital twin object, and the fourth operation includes modifying parameters of the digital twin object.

[0303] Exemplarily, the second device determines whether the digital twin object (AMF_DT_1) has the capability of configuration verification (test) according to the digital twin object information received in S531. When the digitalTwinData parameter contained in AMF_DT_1 indicates the capability of test, the digital twin object has the capability of configuration verification.

[0304] The second device sends a configuration modification request for the digital twin object AMF_DT_1, using the modifyMOI request defined in TS28.531, which includes the identifier of the digital twin object, i.e. AMF_DT_1, and the configuration parameters that need to be modified, i.e., modifying the capacity parameters.

[0305] S570, MDAF generates a new digital twin replica object for testing, and refers to S540 to create a new data stream for transmitting image information of the verification process and results of the configuration modification of the digital twin network replica.

[0306] According to the solution of this application, MDAF provides digital twin functionality and implements the management of digital twin objects by extending MDARequest.

[0307] It should be understood that in various embodiments of the present application, the size of the sequence number of each process does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. Any sequential arrangement that can realize the function of each step should be within the scope of protection of the present application.
