[0093] Digital twins can be used to simulate the state of physical networks and terminals, enabling the verification and performance simulation of new services and technologies to reduce costs and improve reliability. Digital twin tasks can be business processes or functions executed within the digital twin domain. Digital twin tasks may require cooperation between the terminal and the network, such as a terminal initiating a call.

[0094] In this embodiment of the application, the following issues also need to be addressed:

[0095] For physical terminals, since these terminals may not be specifically designed for digital twin tasks, certain special requirements are needed to execute them. These requirements include user authorization, whether the terminal is permitted to execute data twin tasks, and the conditions under which these tasks are permitted or not. Permitted conditions may include permitted time, permitted location, who is permitted to issue the digital twin task, and permitted types of digital twin tasks (such as new business verification or new technology certification).

[0096] In a digital twin domain, the network can be a virtual network, or a combination of virtual and physical networks; the terminal can be a virtual network or a physical terminal. Whether to use virtual or physical terminals, or a virtual or physical network, to perform digital twin tasks depends on the requirements and objectives of the digital twin task. For example, testing service performance under coverage in a certain area might be more suitable with physical terminals; testing an end-to-end process might be feasible with virtual terminals and virtual networks; and testing an end-to-end process of a new technology might be more suitable with a vendor's physical test terminal. For the physical network, a portion of network resources can be allocated to the digital twin domain to perform digital twin tasks.

[0097] In one optional embodiment of this application, the digital twin domain includes at least one of the following: a virtual network (e.g., a virtual core network and a virtual radio access network), a combination of a virtual network and a physical network (e.g., a virtual core network and a physical network's radio access network), resources in the physical network used for digital twin services, a virtual terminal, and a physical terminal.

In an optional embodiment of this application, a digital twin task may include performing one of the following in the digital twin domain: services (including business processes, business functions, etc.), network functions, policies (such as network policies, or policies for terminals), fault reproduction, testing tasks, etc. The digital twin task may be used for, but is not limited to, one of the following: verifying new services, resolving faults and optimizing the network, providing a basis for network expansion, verifying the optimization effect of policies, etc.

[0099] In one alternative embodiment of this application, the digital twin service includes one of the following: one or more digital twin tasks, all digital twin tasks of the terminal.

[0100] In another alternative embodiment of this application, the digital twin service is equivalent to a digital twin task.

[0101] In one optional embodiment of this application, the time information, time period, time period range, and time interval include one of the following: start time, duration, and end time. The duration is counted from the start time or from the time the time information is received. The duration's end time can be used as the end time.

[0102] The digital twin task authorization method, apparatus, communication device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0103] Please see Figure 2 , Figure 2 This is a flowchart illustrating a digital twin task authorization method provided in an embodiment of this application. The method is applied to a first communication device; the first communication device includes, but is not limited to, a network element for twin task management. Figure 2 As shown, the method includes the following steps:

[0104] Step 21: The first communication device acquires the first information.

[0105] In this embodiment, the first information may include at least one of the following:

[0106] The contract information for the digital twin service on the terminal;

[0107] The authorization information of the digital twin service of the terminal, or the authorization information of the digital twin service of the terminal and the validity period information of the authorization information;

[0108] The query result information is used to indicate whether the terminal allows or disallows the digital twin task.

[0109] Optionally, the digital twin service includes one or more digital twin tasks.

[0110] Optionally, the authorization information for the digital twin service of the terminal is obtained from one of the following: the terminal, the application function (AF), or the network element used for user data management (such as UDR or UDM). In one embodiment, the authorization information provided by the terminal or the AF is stored in the network element used for user data management for use by other network elements.

[0111] Optionally, the subscription information for the digital twin service of the terminal can be obtained from a network element (such as UDR or UDM) used for user data management.

[0112] Optionally, the query result information is query result information related to each digital twin task.

[0113] Optionally, the query result information is obtained from one of the following: a terminal, an AF (Automatic Data Provider), or a network element for user data management (such as a UDR or UDM). In one embodiment, the query result information provided by the terminal or AF is stored in the network element for user data management and can be accessed by other network elements.

[0114] Step 22: The first communication device performs a first operation related to digital twin task authorization based on the first information.

[0115] It is easy to understand that in this embodiment, by performing a first operation related to digital twin task authorization based on the obtained first information, the first information includes at least one of the following: the contract information of the terminal's digital twin service; the authorization information of the terminal's digital twin service, or the authorization information of the terminal's digital twin service and the validity time information of the authorization information; and query result information, which is used to instruct the terminal to allow or disallow the digital twin task, thereby enabling the authorization of the digital twin task and supporting the authorization of the digital twin task by the physical terminal.

[0116] In this embodiment of the application, the first operation related to the authorization of performing the digital twin task may include at least one of the following:

[0117] Determine whether the terminal is allowed or not to perform digital twin tasks; (for general terminals, the default is to not allow the execution of digital twin tasks).

[0118] Determine whether to accept or reject the digital twin task; (e.g., determine whether to accept or reject the arriving digital twin task).

[0119] Determine the candidate terminal list for digital twin services;

[0120] Send a first query message, which is used to ask the terminal whether it allows the execution of a digital twin task.

[0121] Therefore, based on the first information obtained, the network, such as the twin task management network element, can determine whether to accept the digital twin task and select candidate terminals to execute the data twin task.

[0122] In one implementation, after determining the candidate terminal list for digital twin services, the first communication device can send this candidate terminal list to the fourth communication device, such as a network element for user data management (e.g., UDR or UDM), for storage for later use.

[0123] In one embodiment, when a digital twin task arrives, the first communication device performs a first operation related to digital twin task authorization based on the first information obtained.

[0124] Optionally, the first operation related to the authorization of the digital twin task mentioned above includes: the first communication device determining that it accepts the digital twin task and determining the list of terminals that accept the digital twin task.

[0125] Optionally, the contract information for the digital twin service on the terminal may include at least one of the following:

[0126] Allowing or disallowing digital twin business operations;

[0127] Conditions under which the terminal is allowed to perform digital twin tasks, and / or conditions under which the terminal is not allowed to perform digital twin tasks;

[0128] Contract type;

[0129] The scope of permitted digital twin tasks, and / or the scope of prohibited digital twin tasks.

[0130] Optionally, the authorization information for the terminal's digital twin service may include at least one of the following:

[0131] Comply with the contract information for digital twin business;

[0132] Allowing or disallowing digital twin business operations;

[0133] Conditions under which the terminal is allowed to perform digital twin tasks, and / or conditions under which the terminal is not allowed to perform digital twin tasks;

[0134] The range of digital twin tasks that are allowed to be performed, and / or the range of digital twin tasks that are not allowed to be performed.

[0135] In one implementation, disallowing the execution of digital twin services includes disallowing the execution of any digital twin task.

[0136] In one implementation, performing a digital twin service is equivalent to complying with the contractual information for the digital twin service.

[0137] It's easy to understand that even if a terminal has already signed up for digital twin services, it can temporarily disallow the execution of these services at the user's request, sending authorization information to the network in this case. In this situation, the authorization information takes precedence over the subscription information. When the terminal resumes permission to execute digital twin services, it can still notify the network via authorization information. At this point, the network can determine whether each arriving digital twin task is permitted to execute, based on the subscription information for the digital twin services.

[0138] Optionally, the conditions under which the terminal is permitted to perform digital twin tasks in the aforementioned contract information and / or authorization information may include at least one of the following:

[0139] The first location range of the terminal;

[0142] The first range of available resources for the terminal; for example, available computing and / or storage resources are greater than and / or equal to x2%, where x2 can be set based on actual needs and is not limited thereto.

[0143] In one embodiment, the first location range of the terminal includes: an identifier for the location range, such as a cell list, a tracking area list, etc., which can be used to indicate that the terminal is only allowed to perform digital twin tasks within this location range; or, the location range is not restricted when performing digital twin tasks.

[0144] In one implementation, the first time period range includes a start time, duration, and end time, which can be used to indicate that the terminal is only allowed to execute digital twin tasks within this time period; alternatively, there may be no time period restriction when executing digital twin tasks, which applies to dedicated digital twin terminals. The duration can be counted from the start time or from the received time period range. The end of the duration count represents the end time.

[0145] In one implementation, the terminal's first available power range indicates that the digital twin task will only be performed if the terminal meets this available power range.

[0146] In one implementation, the first available resource range of the terminal indicates that the digital twin task is executed only if the terminal's computing / storage resources meet this available resource range.

[0147] In one implementation, any of the above ranges includes a default value of: no limitation.

[0149] Second position range;

[0150] Second time period range;

[0151] The first power consumption range for the task; for example, the power consumption of a digital twin task is less than and / or equal to y1% or is unlimited; this y1 can be set based on actual needs and is not limited thereto.

[0152] The scope of the primary terminal capabilities required by the task; for example, the terminal capabilities required by the task could be: application functions; or NAS; or AS; or a combination of the above.

[0153] The first resource overhead range for the task; for example, the computational and / or storage resource overhead of a digital twin task is less than and / or equal to y2%; this y2 can be set based on actual needs and is not limited thereto;

[0154] Description information of permitted digital twin tasks;

[0155] Information about the requester (such as a consumer) that is allowed to request a twin task.

[0156] In one implementation, the second location interval range includes: an identifier for the location interval, such as a cell list or TAlist, indicating that only digital twin tasks whose location belongs to that location interval are allowed to be executed.

[0157] In one implementation, the second time period range includes a start time, duration, and end time, indicating that only digital twin tasks whose execution time falls within this time period are allowed. The duration can be counted from the start time or from the received time period range. The end of the duration count represents the end time.

[0158] In one implementation, the first power consumption range of the task represents a digital twin task that allows power consumption to be less than and / or equal to the power consumption range required by this power consumption range.

[0159] In one implementation, the first resource overhead range of a task represents a digital twin task that allows resource overhead to be less than and / or equal to this resource overhead range.

[0160] In one implementation, a default value for the above range includes: no restriction. For example, for permitted digital twin tasks, there are no restrictions on location ranges, time periods, and / or power consumption, etc.

[0161] Optionally, the conditions under which the terminal is not allowed to perform digital twin tasks in the aforementioned contract information and / or authorization information may include at least one of the following:

[0167] In one implementation, the third time period range includes: start time, duration, end time, etc., which can be used to indicate that the terminal is not allowed to execute digital twin tasks within this time period; or, there is no time period restriction when executing digital twin tasks.

[0168] In one implementation, the second available power range of the terminal indicates that the digital twin task will not be performed if the terminal meets the requirements of this available power range.

[0169] In one implementation, the second available resource range of the terminal indicates that the digital twin task is not executed when the terminal's computing / storage resources meet this available resource range.

[0170] In one implementation, any of the above ranges includes a default value of: no limitation.

[0171] Optionally, the scope of disallowed digital twin tasks in the aforementioned contract information and / or authorization information may include at least one of the following:

[0172] The fourth position range;

[0180] In one implementation, the fourth time period range includes: a start time, a duration, and an end time. The fourth time period range indicates that digital twin tasks whose execution time falls within this time period are not permitted. The duration can be counted from the start time or from the received time period range. The end of the duration count represents the end time.

[0181] In one implementation, the second power consumption range of the task represents a digital twin task that is not allowed to consume less than and / or equal to the power consumption required by this power consumption range.

[0182] In one implementation, the second resource overhead range of a task represents a digital twin task whose resource overhead is not allowed to be less than and / or equal to this resource overhead range.

[0183] In one implementation, a default value for the above range includes: no restriction. For example, for disallowed digital twin tasks, there is no restriction on location range, time period, and / or power consumption.

[0184] Optionally, the description information of the permitted or prohibited digital twin tasks may include at least one of the following:

[0193] In one implementation, if a certain type of digital twin task requires an installation package, and the cost is high or the terminal does not allow the installation package, then the terminal may not allow the execution of the digital twin task; or, if a certain type of digital twin task does not require an installation package, then the terminal may allow the execution of the digital twin task.

[0194] In another implementation, if a certain type of digital twin task requires camera access, but the terminal does not want to grant camera access, then the terminal may not allow the execution of the digital twin task.

[0195] Optionally, the contract type in the above contract information may include any of the following:

[0196] The first type indicates that digital twin business operations are permitted;

[0197] The second type indicates that digital twin services are not permitted.

[0198] The third type indicates that when a digital twin task for a terminal arrives, it is necessary to query the terminal to see if it allows the execution of the digital twin task.

[0199] Optionally, if the first information includes the authorization information of the digital twin service of the terminal and the subscription information of the digital twin service of the terminal, at least one of the following must be satisfied:

[0200] The authorization information has a higher priority than the contract information.

[0201] When the authorization information includes permission to perform digital twin services or compliance with digital twin service contract information, a first operation related to digital twin task authorization is performed based on the contract information.

[0202] When the authorization information includes disallowing the execution of digital twin services (regardless of whether the contract information allows digital twin services), the first operation performed according to the authorization information includes at least one of the following: determining that the terminal does not allow the execution of digital twin tasks, or determining that digital twin tasks are not accepted.

[0203] In one implementation, the authorization information for a terminal's digital twin service takes precedence over the subscription information. For example, if the authorization information for a terminal's digital twin service includes disallowing the execution of digital twin services, but the subscription information for the terminal's digital twin service includes allowing the execution of digital twin tasks, then it is determined that the digital twin task will not be accepted.

[0204] In one embodiment, when the authorization information of the terminal's digital twin service includes disallowing the execution of the digital twin service, and a digital twin task arrives, even if the subscription information of the terminal's digital twin service includes allowing the execution of the digital twin service, the first communication device will refuse or disallow the data twin task related to the terminal.

[0205] In one embodiment, when the authorization information of the terminal's digital twin service includes permission to execute the digital twin service, and the digital twin task arrives, the first communication device determines whether the terminal allows or disallows the execution of the digital twin task based on the terminal's digital twin service subscription information.

[0206] In one implementation, when a digital twin task for a terminal arrives, and the subscription type of the digital twin task is a third type, and there is authorization information for the digital twin service of the terminal sent by the terminal or AF, the first communication device determines whether the terminal allows the digital twin task based on the authorization information, without sending a first query information to the terminal, that is, without querying the terminal whether the digital twin task is allowed to be executed.

[0207] Optionally, when the first information includes query result information, the first communication device may also send first query information to the terminal when the digital twin task arrives, before acquiring the first information. The first query information is used to query whether the terminal allows the execution of the digital twin task. Then, the first communication device receives the query result information from the terminal to determine whether the terminal allows the execution of the digital twin task.

[0213] The contract type in the contract information is the third type, and the obtained query result information indicates that the terminal allows digital twin tasks; or, the contract type in the contract information is the third type, and the authorization information includes permission to execute digital twin services;

[0214] The terminal meets the conditions in the contract information and / or authorization information that allow the terminal to perform digital twin tasks;

[0215] The digital twin task falls within the scope of permitted digital twin tasks as stated in the contract information and / or authorization information.

[0216] 2) Optionally, for the first operation related to the authorization of performing the digital twin task, when the second condition is met, the first communication device determines that the terminal is not allowed to perform the digital twin task.

It is easy to understand that in this case, the authorization information including allowing the execution of digital twin tasks is equivalent to the contract information allowing compliance with digital twin services.

[0225] In one implementation, when the contract type in the contract information is type three, and the authorization information includes disallowing the execution of digital twin services, it is determined that the terminal is not allowed to execute digital twin tasks. It is easy to understand that the authorization information is equivalent to the proactively provided query result information. Therefore, even if it is type three, there is no need to repeat the query.

[0252] The contract type in the digital twin service of the terminal is the third type, and the obtained query result information indicates that the terminal allows the digital twin task; or, the contract type in the contract information is the third type, and the authorization information includes permission to execute the digital twin service;

[0253] The terminal meets the conditions in the contract information and / or authorization information that allow the terminal to perform digital twin tasks.

[0254] 6) Optionally, sending the first query information to the terminal may include: when the sixth condition is met, the first communication device sends the first query information to the terminal.

[0261] Optionally, the digital twin task request may include a list of selected terminals performing digital twin services, or may not include a list of selected terminals performing digital twin services.

[0262] It is easy to understand that this embodiment can support the authorization of digital twin tasks by physical terminals, as well as the network's ability to determine whether to accept digital twin tasks and select candidate terminals to execute them.

[0268] In one embodiment, the second communication device can send second information to the first communication device (such as a network element for twin task management), so that the first communication device can perform relevant operations for digital twin task authorization based on the acquired second information.

[0269] In another implementation, the second communication device can send the second information to a fourth communication device (such as a UDR or UDM), and the fourth communication device stores the second information. The second communication device can also indirectly send the second information to the first or fourth communication device, for example, by sending the second information to an AMF or NEF, and then the AMF or NEF sends the second information to the second or fourth communication device.

[0270] It should be noted that the specific content of the authorization information for the digital twin service of the terminal can be found in the above embodiments, and will not be repeated here.

[0275] Optionally, the second information may be sent in one of the following ways: a registration request message, a service request message, or an inquiry result message; wherein the inquiry result message is used to indicate whether the terminal allows or disallows the digital twin task.

[0276] It is easy to understand that this embodiment can support the authorization of digital twin tasks by physical terminals / AFs.

[0277] Please see Figure 4 , Figure 4 This is a flowchart illustrating a digital twin task authorization method provided in an embodiment of this application. The method is applied to a third communication device; the third communication device includes, but is not limited to, a terminal (UE). Figure 4 As shown, the method includes the following steps:

[0280] In one embodiment, the third communication device can receive a first query message from one of the following and return corresponding query result information: a first communication device (such as a network element for twin task management), or an AMF. In another embodiment, the first communication device sends the first query message to the AMF, and the AMF then sends the first query message to the third communication device.

[0293] It should be noted that the specific content of the authorization information of the digital twin service of the terminal, and / or the specific content of the description information of the digital twin task, can be found in the above embodiments, and will not be repeated here.

[0294] It is easy to understand that this embodiment can support the authorization of digital twin tasks by physical terminals.

[0295] Please see Figure 5 , Figure 5 This is a flowchart of a digital twin task authorization method provided in an embodiment of this application. The method is applied to a fourth communication device; this fourth communication device includes, but is not limited to, network elements for user data management (such as UDR or UDM). Figure 5 As shown, the method includes the following steps:

[0296] Step 51: The fourth communication device receives the information acquisition request.

[0297] The information acquisition request is used to acquire one of the following: third information, terminal's contract information, or information related to the terminal's digital twin business.

[0298] Understandably, the contract information of the aforementioned terminal includes the contract information for the terminal's digital twin service. It is easy to understand that the terminal's contract information includes contract information for one or more services. When a request is made to retrieve contract information, all contract information of the terminal (including the contract information for the digital twin service) can be returned.

[0299] The relevant information of the digital twin service of the aforementioned terminals includes, but is not limited to, at least one of the following: contract information of the digital twin service, authorization information of the digital twin service, authorization duration of the authorization information of the digital twin service, and a list of candidate terminals for the digital twin service.

[0307] In one embodiment, the subscription information for the digital twin service of the terminal in the third information includes a subscription type, which can be any one of the following: a first type or a third type; wherein, the first type indicates that the execution of the digital twin task is permitted; and the third type indicates that when a digital twin task for the terminal arrives, the terminal is asked whether it is permitted to execute the digital twin task.

[0308] The contract information for the digital twin service on the terminal, such as Figure 2 As previously mentioned, this will not be repeated here.

[0309] Authorization information for the terminal's digital twin service, such as Figure 2 As previously mentioned, this will not be repeated here.

[0310] It is easy to understand that through this embodiment, the twin task management network element can obtain the contract information and / or authorization information of the terminal's digital twin service, thereby supporting the determination of whether to accept the digital twin task and the selection of candidate terminals to execute the data twin task.

[0311] Please see Figure 6 , Figure 6 This is a flowchart illustrating a digital twin task authorization method provided in an embodiment of this application. The method is applied to a fifth communication device; this fifth communication device includes, but is not limited to, an AF (Automatic Requester) and a requester of the digital twin task (such as a consumer). Figure 6 As shown, the method includes the following steps:

[0312] Step 61: The fifth communication device sends a digital twin task request, which includes a description of the digital twin service.

[0313] In some embodiments, the fifth communication device may send a digital twin task request to the first communication device (such as a network element for twin task management, which may be referred to as: twin task management network element).

[0314] It should be noted that the specific content included in the description information of the digital twin task can be found in the above embodiments, and will not be repeated here.

[0317] In some embodiments, the fifth communication device can receive indication information from the terminal indicating whether to accept the digital twin task.

[0318] It is easy to understand that this embodiment can support initiating digital twin task requests to the twin task management network element.

[0319] The following is combined with Figures 7 to 10 The embodiments of this application will be described in detail.

[0320] Example 1

[0321] like Figure 7 As shown, the digital twin task authorization process in Embodiment 1 of this application includes the following steps:

[0322] Step 71: The twin task management network element receives a digital twin task request related to the physical UE from the AF / digital twin task requester (consumer). The request includes a description of the digital twin task. Optionally, the request may also include a list of selected UEs performing the digital twin task.

[0323] Step 72: Optionally, when the request in step 71 includes a list of UEs, the twin task management network element requests the UDM to obtain the subscription information of the UE's digital twin service.

[0324] Alternatively, when the request in step 71 does not include a list of UEs, the twin task management network element can filter and request the UDM to obtain the UE's digital twin service subscription information.

[0325] Step 73: The twin task management network element obtains the UE's digital twin service subscription information from the UDM, and proceeds to step 74 or step 76 based on the obtained subscription information.

[0326] For example, the contract information includes the contract type for digital twin services. When the contract type is the first type or the second type, that is, when digital twin services are allowed or not allowed, proceed to step 76.

[0327] For example, the contract information includes the contract type for digital twin services. When the contract type is the third type, that is, when a digital twin task for the terminal arrives, it is necessary to ask the terminal whether to allow the execution of the digital twin task, then proceed to step 74.

[0328] Step 74: The twin task management network element sends a first query message to the UE, which is used to ask the UE whether it allows the execution of the digital twin task.

[0329] Optionally, the twin task management network element can directly send the first query information to the UE, or send the first query information to the UE through the AMF.

[0330] Optionally, the first query information includes at least one of the following: description information of the digital twin task, and authorization query request for the digital twin task.

[0331] Step 75: The UE sends an inquiry result information to the twin task management network element. The inquiry result information is used to indicate whether the terminal allows or disallows the digital twin task.

[0332] Step 76: Based on the contract information obtained in Step 73 and / or the query result information received in Step 75, the twin task management network element determines whether to accept or not accept the digital twin task.

[0333] Specifically, if no UE satisfies the digital twin task, the digital twin task is rejected / not accepted; otherwise, the digital twin task is accepted and a list of UEs to execute the digital twin task is determined. Optionally, when accepting the digital twin task, the AF / digital twin task consumer returns the list of UEs that accepted the digital twin task and / or selected UEs.

[0334] Example 2

[0335] like Figure 8 As shown, the digital twin task authorization process in Embodiment 2 of this application includes the following steps:

[0336] Step 81: The twin task management network element obtains the UE's digital twin service subscription information from the UDM in advance, and forms a list of UEs that can perform digital twin tasks.

[0337] Optionally, the subscription type in the digital twin service subscription information of the UEs in the UE list includes one of the following:

[0338] The first type allows for the execution of digital twin tasks;

[0339] The third type involves querying the terminal to determine whether it is permitted to execute the digital twin task when a digital twin task for the terminal arrives.

[0340] It is easy to understand that UEs with a contract type of type 2, namely "not allowed to perform digital twin tasks", are not included in the UE list.

[0341] Step 82: The twin task management network element receives a digital twin task request related to the physical UE from the AF / twin task consumer. The request includes a description of the digital twin task. The request does not include a list of selected UEs to perform the digital twin task.

[0342] Step 83: The twin task management network element selects a UE that meets the conditions based on the description information of the digital twin task. For the selected UE, when the subscription type of the UE's digital twin task is type three, that is, when the digital twin task for the terminal arrives, it is necessary to query the terminal whether to allow the execution of the digital twin task, proceed to step 84.

[0343] Steps 84-85 are the same as steps 74-75 in Example 1, and will not be repeated here.

[0344] Step 86: If no UE satisfies the digital twin task, reject / do not accept the digital twin task; otherwise, accept the digital twin task and determine the list of UEs to perform the digital twin task. Optionally, when accepting the digital twin task, return the list of UEs that accepted the digital twin task and / or selected UEs to the AF / digital twin task consumer.

[0345] Example 3

[0346] like Figure 9 As shown, the digital twin task authorization process in Embodiment 3 of this application includes the following steps:

[0347] Step 91: The UE or AF sends the authorization information for the UE's digital twin service and / or the validity period of the authorization information to the network, such as UDM / UDR.

[0348] In one implementation, the network can overwrite the UE's digital twin service subscription information based on the UE's digital twin service authorization information.

[0349] In another implementation, the network can simultaneously store the authorization information of the UE's digital twin service and the subscription information of the UE's digital twin service.

[0350] In another implementation, the network can store the authorization information of the UE's digital twin service, but the UE's digital twin service subscription information does not exist in the network.

[0351] Step 92: The twin task management network element receives a digital twin task request related to the physical UE from the AF / twin task consumer. The request includes a description of the digital twin task. Optionally, the request may also include a list of selected UEs performing the digital twin task.

[0352] Step 93: When the request in step 71 includes a list of UEs, the twin task management network element requests the UDM to obtain the subscription information and / or authorization information of the twin services related to the UEs.

[0353] Step 94: The twin task management network element receives the UE-related twin service subscription information and / or UE digital twin service authorization information from the UDM.

[0354] Step 95: The twin task management network element determines whether to accept or not to accept the digital twin task based on the obtained contract information and / or authorization information.

[0355] Specifically, if no UE satisfies the digital twin task, the digital twin task is rejected / not accepted; otherwise, the digital twin task is accepted and a list of UEs to execute the digital twin task is determined. Optionally, when accepting the digital twin task, the AF / digital twin task consumer returns the list of UEs that accepted the digital twin task and / or selected UEs.

[0356] It should be noted that in this embodiment 3, a query process similar to step 74 in embodiment 1 can also be triggered, which will not be described in detail here.

[0357] Example 4

[0358] Step 101: The twin task management network element obtains information about UEs other than those with a subscription type of type 2, i.e., "not allowed to perform digital twin tasks" (e.g., UEs with a subscription type of type 1 and / or UEs with a subscription type of type 3), and the subscription information of the digital twin services of the UEs from the UDM to form a candidate UE list.

[0359] Step 102: The UE or AF sends the authorization information of the UE's digital twin service and / or the validity period of the authorization information to the network, such as the twin mission management network.

[0360] Optionally, the twin task management network element can determine the candidate UE list for the data twin task based on at least one of the following:

[0361] (1) UE's digital twin service contract information;

[0362] (2) Authorization information for the UE's digital twin service;

[0363] (2) The authorization information of the UE’s digital twin service and the validity period of the authorization information.

[0364] In one implementation, the network can overwrite the UE's digital twin service subscription information based on the UE's digital twin service authorization information.

[0365] In another implementation, the network can simultaneously store the authorization information of the UE's digital twin service and the subscription information of the UE's digital twin service.

[0366] In another implementation, the network can store the authorization information of the UE's digital twin service, but the UE's digital twin service subscription information does not exist in the network.

[0367] Step 103: The twin task management network element receives a digital twin task request related to the physical UE from the AF / twin task consumer. The request includes a description of the digital twin task. The request does not include a list of selected UEs to perform the digital twin task.

[0368] Step 104: The twin task management network element determines the UEs that meet the conditions based on the description information of the digital twin task and the candidate UE list.

[0369] Optionally, for the selected UE, when the subscription type of the UE's digital twin task is the third type, that is, when the digital twin task about the terminal arrives, it is necessary to ask the terminal whether to allow the execution of the digital twin task, and there is no "authorization information of the UE's digital twin service" about the UE or about the digital twin task, proceed to step 105.

[0370] Optionally, for the selected UE, when the subscription type of the UE's digital twin task is the third type, that is, when the digital twin task about the terminal arrives, it is necessary to ask the terminal whether to allow the execution of the digital twin task, and when there is "authorization information of the UE's digital twin service" about the UE or about the digital twin task, it can be directly determined whether the UE executes the digital twin task, and then it can directly proceed to 107.

[0371] Steps 105-106 are the same as steps 74-75 in Example 1, and will not be repeated here.

[0372] Step 107: If no UE satisfies the digital twin task, reject / do not accept the digital twin task; otherwise, accept the digital twin task and determine the list of UEs to perform the digital twin task. Optionally, when accepting the digital twin task, return the list of UEs that accepted the digital twin task and / or selected UEs to the AF / digital twin task consumer.
