However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0039] In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0040] The following will, with reference to the accompanying drawings, elaborate in detail on the specific implementation manners of the embodiments of the present disclosure.

[0041] Figure 1 A schematic diagram of an exemplary system architecture to which the cross-network data service method according to the embodiments of the present disclosure can be applied is shown.

[0042] As Figure 1 shown, the system architecture includes a terminal device, an access network, and a core network.

[0043] The core network includes various network entities of the core network, including but not limited to the evolved Access and Mobility Management Function (eAMF) network element, Service Orchestration Function (SOF) network element, Data Service Management Function (DSMF) network element, Data Plane Function (DPF) network element, Data Storage Function (DSF) network element, Service Exposure Function (SEF) network element, Connection Service Management Function (CSMF) network element. In addition, it can also include the Data Plane Function (DPF) network element, Network Exposure Function (NEF) network element, Policy Control Function (PCF) network element, Session Management Function (SMF) network element, Unified Data Management (UDM) network element, etc. It should be noted that the specific type of the core network is not limited in the embodiments of the present disclosure.

[0044] As Figure 1 shown, the eAMF network element supports terminal devices with different mobility management requirements. The terminal device interacts with the eAMF network element through the N1 interface, the access network interacts with the eAMF network element through the N2 interface, the access network interacts with the UPF network element through the N3 interface, and the UPF network element interacts with the CSMF network element through the N4 interface.

[0045] The SOF network element is responsible for the requirements and decomposition of data services, the mapping and selection of corresponding resources, and the orchestration strategy, etc. The SOF network element receives data service requirements, transposes and splits the data service requirements into corresponding data service tasks, and selects and orchestrates the DSMF network elements required for the split data service tasks.

[0046] The DSMF network element is responsible for selecting specific NF such as DPF gateways and DSF network elements with different data service capabilities according to the orchestration results of the SOF network element, forming an executable logical topology of UE, RAN, DPF network element, and DSF network element, and controlling this working chain to implement specific data service functions. The DSMF network element also needs to support the data service capability reporting functions of DPF network elements, DSF network elements, etc.

[0047] The DPF network element realizes functions such as data collection, transmission, preprocessing, and analysis. The DSF network element stores collected data, data service results, etc. The CSMF network element can receive connection service tasks from the SOF network element and control the establishment, modification, and release of the terminal device to the data network (DN). The SEF network element can provide the opening of network services externally.

[0048] The data center (DC) can obtain data from data sources, including the collection of user data, network data, artificial intelligence (AI) data, perception data, etc. Data storage (DS) is used to store collected data, data service results, etc. The data plane (DP) is used for data preprocessing and data analysis, etc.

[0049] As Figure 2 shown, the DC can include terminal devices, access networks, eAMF network elements, UPF network elements, DPF network elements, etc.; the DP can include DPF network elements; the DS can include DSF network elements.

[0050] The terminal device can also be called UE (User Equipment). In specific implementations, the terminal device can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), a wearable device, or a vehicle-mounted device, etc. It should be noted that the specific type of the terminal device is not limited in the embodiments of the present invention.

[0051] With the continuous development of communication technologies, the research on 6G network systems has been steadily advancing. In future networks, data generated and consumed by intelligence, perception, and network operations need to be uniformly collected, preprocessed, stored, and analyzed. Therefore, implementing efficient and flexible data services based on data service network systems has become a trend, and at the same time, many challenges are also faced.

[0052] How to efficiently manage and orchestrate data service processes to ensure that data services can be executed according to predefined business logics and Service Level Agreement (SLA) requirements has become a technical problem that needs to be solved urgently.

[0053] In related technologies, most data service systems adopt centralized management, that is, all data service requests are processed by a central node, which not only limits the scalability of the system, but also may lead to uneven resource allocation and performance bottlenecks. In a distributed network architecture, how to implement cross-network data services is also a current technical challenge.

[0054] To solve at least some of the above technical problems, the present disclosure provides a cross-network data service method. Through a first network element, accurate decomposition, orchestration, and deployment of load data service requirements can be achieved, improving service orchestration capabilities; the first network element can intelligently select a suitable second network element according to business logics and SLA requirements, so that the second network element selects a data service execution network element according to tasks, thereby efficiently meeting diverse data service requirements and effectively solving problems such as poor scalability and uneven resource allocation in data service systems.

[0055] The following will describe this exemplary embodiment in detail with reference to the accompanying drawings and embodiments. First, the present disclosure provides a cross-network data service method in an embodiment. This method can be executed by any electronic device with computing and processing capabilities. For example, this method can be executed by a first network element, or by a second network element, or by the interaction between the first network element and the second network element.

[0056] Figure 3 The flowchart of a cross-network data service method executed by a first network element provided in an embodiment of the present disclosure is shown. As Figure 3 shown, the cross-network data service method provided in an embodiment of the present disclosure is applied to a first network element, and this method mainly includes the following steps: S302. In response to a data service request initiated by a data service requester, perform task orchestration on the data service request to obtain task information of the data service task, where the data service task includes at least one task to be executed.

[0057] In one embodiment, the data service requester may be a Network Function (NF), a terminal device, a third-party application, etc. An NF is a logical entity that performs specific functions in a 6G network, and third-party applications may include applications such as smart city infrastructure, virtual reality, and industrial automation.

[0058] A data service request is a request used to indicate data service - related requirements to a first network element. The request message of the data service request may include, but is not limited to, the service type of the requested data service, the requested data service area, the SLA requirements of the requested data service, etc. Among them, the service type of the requested data service may include perception - type requests, AI - type requests, etc., and the requested data service area may include area - oriented perception, target - oriented perception, etc. The SLA requirements of the requested data service are used to determine the service - level target and are the service quality requirements for the requested data service.

[0059] The first network element can perform requirement escape and split the data service request into corresponding data service tasks. The number of tasks to be executed in the data service tasks can be determined according to actual requirements. The task to be executed is the smallest unit that a data service execution network element can execute.

[0060] When splitting the data service request, the first network element can split it based on the type of the required data service execution network element, SLA requirements, etc.

[0061] S304: Select a second network element for the data service task. The second network element is a network element that can provide the capabilities and resources required to execute at least one task to be executed.

[0062] In one embodiment, when there are multiple network elements that can provide the capabilities and resources required to execute at least one task to be executed, one of the above - mentioned network elements can be randomly selected as the second network element, or the network element with the highest available capabilities and resources can be selected as the second network element.

[0063] The capabilities and resources that the second network element can provide are the sum of the capabilities and resource information of the data service execution network elements with data service capabilities received by the second network element. The capabilities of each data service execution network element may include capabilities such as data collection, data processing, data analysis, and data storage, and the resource information of the data service execution network element may include resources such as data and computing power.

[0064] The first network element matches the task information of the data service task with the capabilities and resource information of the second network element that can provide data service capabilities, so as to select a second network element for the data service task.

[0065] S306: Send the task information of the data service task to the second network element, so that the second network element selects a target data service execution network element for each task to be executed based on the capabilities and resource information of the data service execution network element, and deploys the corresponding task to be executed to the target data service execution network element to instruct the target data service execution network element to execute the corresponding task to be executed, obtain a data service result, and return the data service result to the data service requester.

[0066] In one embodiment, a first network element sends task information of a data service task to a second network element. The task information of the data service task may include, but is not limited to, task ID, task resource requirements, Quality of Service (QoS) requirements, input data address, output result address, and other information. The task ID is used to distinguish different tasks to be executed and may be represented in ways such as task names, numbers, letters, symbols, etc. The task resource requirements may indicate relevant information of the data service execution network element required to execute the task to be executed. For example, the type of the data service execution network element. The QoS requirements are mapped based on the SLA requirements of the requested data service.

[0067] The second network element may screen suitable target data service execution network elements for each task to be executed based on the capabilities and resource information reported by the data service execution network elements to execute the corresponding tasks to be executed. Based on the logical topology relationships of the tasks to be executed, a data interaction path between the data service execution network elements is established.

[0068] The second network element sends task deployment information to the selected target data service execution network elements. The task deployment information may include task configuration information, data interaction path information, input data address, output result address, etc. The task configuration information may include algorithm configuration information and / or algorithm configuration information. The data interaction path information is used to indicate the information of the start node and the destination node of the data transmission path. The input data address and the output result address are used to determine the input node address and the output node address information, and an IP address may be used.

[0069] In the implementation manner of the present disclosure, through the first network element, precise decomposition, orchestration, and deployment of load data service requirements can be achieved, improving the service orchestration ability; the first network element can intelligently select a suitable second network element according to the service logic and SLA requirements, so that the second network element selects a data service execution network element according to the task, thereby efficiently meeting diverse data service requirements and effectively solving problems such as poor scalability and uneven resource allocation in the data service system.

[0070] Figure 4 The flowchart of another cross-network data service method executed by the first network element provided by the embodiment of the present disclosure is shown. On the basis of Figure 3 the embodiment, S304 is further refined into S3042 to limit the determination method of the second network element. As Figure 4 shown, in one embodiment, the cross-network data service method of this embodiment includes S302, S3042, and S306, where S304 is to select a second network element for the data service task and includes: S3042: Select a second network element for the data service task based on the capabilities and resource information of the second network element.

[0071] It should be noted that the specific implementation manners of S302 and S306 in this embodiment are the same as those of S302 and S306 in the foregoing embodiment, and will not be elaborated here.

[0072] In one embodiment, the capability and resource information of the second network element is obtained by aggregating the data service capability and resource information reported by the data service execution network element.

[0073] The first network element stores the capability and resource information of the second network element. The first network element can match the network elements capable of providing the capability and resource information stored in advance with each task to be executed. When a network element that can provide the capabilities and resources required to execute at least one task to be executed is matched, the network element is selected as the second network element.

[0074] In the embodiment of the present disclosure, by matching the capability and resource information of the second network element with each task to be executed, the second network element is selected for the data service task, and an appropriate second network element can be intelligently selected according to the service logic and SLA requirements, thereby effectively meeting the diverse data service requirements.

[0075] Figure 5 The flowchart of another cross-network data service method executed by the first network element provided by the embodiment of the present disclosure is shown. On the basis of Figure 3 the embodiment, S303 is added before S304 to limit the situation where the first network element stores the capability and resource information of the second network element. As Figure 5 shown, in one embodiment, before selecting the second network element for the data service task in S304, the method further includes: S303: Receive the capability and resource information of the second network element reported by the second network element, and store the capability and resource information of the second network element.

[0076] In one embodiment, when the data service execution network elements with data service capabilities report the capability and resource information of the data service execution network elements to the second network element, the second network element stores and aggregates the capability and resource information of each data service execution network element to obtain the capability and resource information of the second network element, and reports the capability and resource information of the second network element to the first network element.

[0077] After receiving the capability and resource information of the second network element reported by the second network element, the first network element can store it in the database of the first network element for subsequent screening of the second network element for the data service task.

[0078] It should be noted that the capability and resource information of the second network element can be recorded in a data table.

[0079] Figure 6The flowchart of another cross-network data service method executed by the first network element provided by the embodiments of the present disclosure is shown. Based on the Figure 3 embodiment, S306 is refined into S3062 to define the generation method of the task information of the data service task. As Figure 6 shown, in one embodiment, the cross-network data service method provided in this embodiment includes S302~S304, S3062. Among them, S306 responds to the data service request initiated by the data service requester, performs task orchestration on the data service request, and obtains the task information of the data service task, including: S3062. Based on the service logic and SLA requirements, perform task orchestration on the data service request to obtain multiple to-be-executed tasks with dependencies, and generate the task information of each to-be-executed task.

[0080] In one embodiment, the first network element can decompose the data service request based on the service logic and SLA requirements to obtain multiple to-be-executed tasks with dependencies. The dependencies of the to-be-executed tasks are determined by the service logic and are used to define the order in which the data service execution network elements execute the to-be-executed tasks.

[0081] The first network element assigns a task ID to each to-be-executed task, maps the SLA requirements to the QoS of each to-be-executed task, and estimates the resource requirements of each to-be-executed task, so as to obtain the task information of each to-be-executed task, so that the first network element can select a suitable second network element according to the task information of each to-be-executed task.

[0082] In the embodiment of the present disclosure, the first network element orchestrates the service process based on the service logic and SLA requirements, decomposes the complex data service request into multiple to-be-executed tasks with dependencies, generates the QoS and resource requirements of each to-be-executed task, and then assigns the to-be-executed tasks to a suitable second network element for deployment and execution, so as to achieve efficient service orchestration and task deployment and efficiently meet diverse data service requirements.

[0083] Figure 7 The flowchart of a cross-network data service method executed by a second network element provided by the embodiments of the present disclosure is shown. As Figure 7 shown, in one embodiment, a cross-network data service method provided by the embodiments of the present disclosure is applied to the second network element. The method mainly includes the following steps: S702. Receive the task information of the data service task sent by the first network element. The task information of the data service task is obtained by the first network element performing task orchestration on the data service request in response to the data service request initiated by the data service requester. The data service task includes at least one to-be-executed task.

[0084] In one embodiment, the data service requester can be a network function (NF), a terminal device, a third-party application, etc.

[0085] A data service request is a request used to indicate data service-related requirements to a first network element. The request message of the data service request can include, but is not limited to, the service type of the requested data service, the requested data service area, the SLA requirements of the requested data service, etc.

[0086] The first network element can perform requirement escape and split the data service request into corresponding data service tasks. The number of tasks to be executed in the data service tasks can be determined according to actual requirements. The task to be executed is the smallest unit that the data service execution network element can execute.

[0087] The task information of the data service task can include, but is not limited to, task ID, task resource requirements, Quality of Service (QoS) requirements, input data address, output result address, etc. The task ID is used to distinguish different tasks to be executed and can be represented in ways such as task name, number, letter, symbol, etc. The task resource requirements can indicate relevant information of the data service execution network element required to execute the task to be executed. For example, the type of the data service execution network element. The QoS requirements are mapped based on the SLA requirements of the requested data service.

[0088] S704. Select a target data service execution network element for each task to be executed based on the capabilities and resource information of the data service execution network element.

[0089] The second network element can screen suitable target data service execution network elements for each task to be executed based on the capabilities and resource information reported by the data service execution network element to execute the corresponding tasks to be executed. Based on the logical topology relationship of each task to be executed, establish a data interaction path between the data service execution network elements.

[0090] The target data service execution network element is a data service execution network element whose capabilities and resources can meet the capabilities and resources required to execute the task to be executed.

[0091] S706. Deploy the corresponding task to be executed to the target data service execution network element to instruct the target data service execution network element to execute the corresponding task to be executed and send the obtained data service result to the data service requester.

[0092] In one embodiment, the above S706 deploys corresponding tasks to be executed to the target data service execution network element, including: sending task deployment information of the corresponding tasks to be executed to the target data service execution network element, where the task deployment information includes at least one of task configuration information, data interaction path information, input data address, and output result address. The task configuration information may include algorithm configuration information and / or algorithm configuration information. The data interaction path information is used to indicate the information of the start node and the destination node of the data transmission path. The input data address and the output result address are used to determine the input node address and the output node address information, and an IP address may be used.

[0093] In the embodiment of the present disclosure, through the interaction between the second network element and the first network element, the second network element receives the task information of the data service task to meet the data service requirements of the data service requester; on the other hand, the second network element selects the target data service execution network element for each task to be executed according to the capabilities and resource information of the data service execution network element, further improving the reliability of the data service, enhancing the user experience, and meeting diverse data service requirements.

[0094] Figure 8 The flowchart of another cross-network data service method executed by the second network element provided by the embodiment of the present disclosure is shown. As Figure 8 shown, in one embodiment, before S704 selects the target data service execution network element for each task to be executed based on the capabilities and resource information of the data service execution network element, the method further includes: S802: Receive the capabilities and resource information of the data service execution network element periodically reported by the data service execution network element; S804: Aggregate and store the capabilities and resource information of the data service execution network element to obtain the capabilities and resource information of the second network element; S806: Report the capabilities and resource information of the second network element to the first network element.

[0095] In S802, the data service execution network element may periodically report its own capabilities and resource information to the second network element, and the reporting period of the capabilities and resource information of the data service execution network element may be determined according to actual needs, and the present disclosure does not make specific limitations.

[0096] The second network element may also adopt a heartbeat mechanism to periodically send a capabilities and resource information reporting instruction to the data service execution network element to instruct the data service execution network element to report its own capabilities and resource information.

[0097] In S804, the second network element may aggregate the capabilities and resource information of each data service execution network element to obtain the capabilities and resource information of the second network element and store it.

[0098] The capabilities and resource information of the second network element and the capabilities and resource information of the data service execution network element can be stored in the form of a data table.

[0099] In S806, when the capabilities and resource information of the second network element are updated, the capabilities and resource information of the second network element can be reported to the first network element so that the first network element can update the corresponding information.

[0100] In the embodiments of the present disclosure, the second network element obtains the capabilities and resource information of the data execution network element and aggregates them to obtain the capabilities and resource information of the second network element, and reports them to the first network element, which can effectively monitor the capabilities and resource information of the data service execution network element associated with the second network element and provide effective support for data service requirements.

[0101] It can be understood that for the first network element executing the above method, it can also be a chip or a chip system disposed within the first network element; for the second network element executing the above method, it can also be a chip or a chip system disposed within the second network element, and the present application does not make specific limitations thereon.

[0102] For the first network element and the second network element in the above method, the first network element can be a SOF network element, the second network element is a DSMF network element, and the data service execution network element is an NF network element.

[0103] To deepen the understanding of the embodiments of the present disclosure, the following is combined with Figure 9 and Figure 10 for detailed description. Taking the first network element as a SOF network element, the second network element as a DSMF network element, and the data service execution network element as NFs as an example for illustration.

[0104] As Figure 9 shown, the cross-network data service method provided by the present disclosure includes the following steps: S902, NFs periodically report their capabilities and resource information to the DSMF network element; S904, the DSMF network element stores and aggregates the capabilities and resource information of the NF to obtain the capabilities and resource information of the DSMF network element; S906, the DSMF network element reports the capabilities and resource information of the DSMF network element to the SOF network element.

[0105] As Figure 10 shown, the cross-network data service method provided by the exemplary embodiments of the present disclosure includes the following steps: S1002, the data service requester sends a data service request to the SOF network element, and the request message of the data service request may include, but is not limited to, the service type of the requested data service, the requested data service area, the SLA requirements of the requested data service, etc.; S1004. The SOF network element decomposes the data service request into data service tasks, assigns task IDs to each task to be executed, maps the SLA requirements to the QoS of each task to be executed, estimates the task resource requirements, and selects a DSMF network element for the data service task; S1006. The SOF network element sends the task information to the selected DSMF network element; S1008. The DSMF network element selects an NF; S1010. The DSMF network element sends the task deployment information to the selected NF. The task deployment information includes, but is not limited to, task configuration information, data interaction path information, input data address, output result address, etc.

[0106] In the present disclosure, in order to facilitate the SOF network element to better perform service orchestration for services, map the decomposed tasks to be executed to a suitable DSMF network element, the SOF network element needs to have the capability and resource information of each DSMF network element; in order to enable the DSMF network element to deploy the tasks to be executed to a suitable NF, the DSMF network element needs to have the capability and resource information of each NF in the region, so as to provide better quality data services.

[0107] Figure 11 Shows a flowchart of a cross-network data service method provided by an embodiment of the present disclosure applied to a distributed network. As Figure 11 shown, in one embodiment, the present disclosure provides a cross-network data service method applied to a distributed network. The distributed network includes a central network and multiple subnets; the method mainly includes the following steps: S1102. The first network element of the first target network responds to the data service request initiated by the data service requester, performs task orchestration on the data service request, and obtains the task information of the data service task. The data service task includes at least one task to be executed.

[0108] In one embodiment, the data service requester sends a data service request to the first network element of the first target network. The data service request may carry information such as service type and service requirements. The service type may include, but is not limited to, types such as high-precision positioning, imaging mapping, unmanned aerial vehicle flight supervision, and environmental monitoring in sensing services. The service requirements include requirements such as sensing mode, sensing area, sensing QoS requirements, and sensing data update frequency.

[0109] The first network element of the first target network performs task orchestration according to the data service request, decomposes the data service request into multiple tasks to be executed, maps the SLA to the QoS of the tasks to be executed, and obtains the task information of the tasks to be executed.

[0110] S1104. The second target network selected by the first network element of the first target network for the data service task is the central network. The second target network is a network that can provide the capabilities and resources required to execute at least one task to be executed.

[0111] The first network element of the first target network selects a suitable second target network according to the task information of the task to be executed and the information on the capabilities and resources required for the task to be executed.

[0112] S1106. The first network element of the first target network sends the task information of the data service task to the second target network, so that the second target network processes the data service task to obtain a data service result and returns the data service result to the data service requester; where the first target network is the central network in the distributed network, and the second target network is a subnet in the distributed network; or the first target network is a subnet in the distributed network, and the second target network is the central network in the distributed network.

[0113] The task information of the data service task may include, but is not limited to, information such as task ID, task resource requirements, Quality of Service (QoS) requirements, input data address, output result address, etc. The task ID is used to distinguish different tasks to be executed and can be represented in ways such as task name, number, letter, symbol, etc. The task resource requirements may indicate relevant information about the data service execution network element required to execute the task to be executed. For example, the type of the data service execution network element. The QoS requirement is mapped according to the SLA requirement of the requested data service.

[0114] The number of subnets in the distributed network can be determined according to actual needs and is not specifically limited herein.

[0115] In one embodiment, the first target network may be the central network in the distributed network, and the second target network is a subnet in the distributed network, that is, the data service requester sends a data service request to the central network. The central network processes the data service request and selects a suitable subnet. The subnet selects a suitable target data service execution network element according to the task information to execute the task to be executed, obtains the data service result and returns it to the data service requester.

[0116] In one embodiment, the first target network may also be a subnet in the distributed network, and the second target network is the central network in the distributed network, that is, the data service requester sends a data service request to the one subnet. The one subnet may send the data service request or the task information of the corresponding task to be executed to the central network, and the central network selects a suitable target data service execution network element to provide the data service result to the data service requester.

[0117] In the embodiments of the present disclosure, through the cooperation between the first network element of the first target network and the second target network, data services can be flexibly scheduled and executed among multiple networks, improving the overall performance and resource utilization rate of the distributed network.

[0118] In one embodiment, when the first target network is the central network in the distributed network and the second target network is a subnet in the distributed network, the second target network selected by the first network element of the first target network for the data service task in S1104 being the central network includes: selecting, according to the pre-stored configuration information of multiple subnets, a second target network for the data service task.

[0119] The configuration information of multiple subnets may include information such as operator resources, and may also include the capabilities and resource information of the second network elements corresponding to each subnet.

[0120] After each second network element of each subnet receives the respective capabilities and resource information reported by each data service execution network element, it summarizes them to obtain the configuration information of each subnet, and reports the configuration information of each subnet to the central network. The central network stores the configuration information of each subnet, so that the central network selects a suitable subnet as the second target network for the data service task according to the configuration information of each subnet.

[0121] The first network element of the central network forwards the task information of the task to be executed to the first network element of the subnet through the service proxy. The selected subnet selects a suitable second network element based on the task requirements and the resource and capability information reported by the second network element of the subnet, and sends the task information of the task to be executed to the second network element selected by the subnet, so that the second network element selected by the subnet selects a target data service execution network element for executing the task based on the capabilities and resource information reported by each data service execution network element, establishes a data interaction path between each target data service execution network element, and sends the task to be executed to the corresponding target data service execution network element. After the task is executed, the target data service execution network element returns the data service result to the data service requester.

[0122] In one embodiment, when the first target network is a subnet in the distributed network and the second target network is the central network in the distributed network, the second target network selected by the first network element of the first target network for the data service task in S1104 being the central network includes: if the resources of the first target network cannot meet the requirements of the data service task or the first target network does not support the relevant data service capabilities, the first network element of the first target network selects the second target network for the data service task as the central network; Among them, the first network element of the first target network sending the task information of the data service task to the second target network includes: The first network element of the first target network sends a data service request or task information of a data service task to the first network element of the second target network through a service agent, so that the first network element of the second target network selects a corresponding second network element based on the task requirement and the capability and resource information of the second network element in the second target network, and the second network element selected in the second target network selects a target data service execution network element for each task to be executed based on the capability and resource information of the data service execution network element, deploys the corresponding task to be executed to the target data service execution network element, instructs the target data service execution network element to execute the corresponding task to be executed, and sends the obtained data service result to the data service demander; or enables the second target network to select a target data service execution network element for each task to be executed based on the capability and resource information of the data service execution network element, and sends the corresponding task to be executed to the target data service execution network element, so as to instruct ... The agent sends the task information of the data service task to the third target network. The first network element in the third target network selects the corresponding second network element based on the task requirements and the capabilities and resource information of the second network element in the third target network. The second network element selected in the third target network selects a target data service execution network element for each task to be executed based on the capabilities and resource information of the data service execution network element, deploys the corresponding task to be executed to the target data service execution network element to instruct the target data service execution network element to execute the corresponding task to be executed, and sends the obtained data service result to the data service demander. The third target network is another subnet in the distributed network that can provide the capabilities and resources required to execute at least one task to be executed.

[0123] In one embodiment, when the first target network finds that it lacks resources or does not support relevant data service capabilities, the second target network may be determined as the central network.

[0124] The first network element of the first target network may initiate a data service request to the central network (ie, the second target network) through a service agent, or may forward the decomposed task information of the to-be-executed task to the first network element of the central network (ie, the second target network).

[0125] In one implementation, the execution of the tasks to be executed can be achieved through interaction between the first network element and the second network element in the central network. The principle of the central network processing the tasks to be executed is the same as the principle of the subnet processing the tasks to be executed in the aforementioned embodiment, and will not be repeated here.

[0126] In another implementation, when the central network receives a data service request or task information of a task to be executed sent by the first target network, it can select a third target network to execute the task to be executed. The first network element of the central network can send the task information to the first network element of the third target network through a service agent. The principle of the third target network processing the task to be executed is the same as the principle of the subnet processing the task to be executed in the aforementioned embodiment, and will not be repeated here.

[0127] In the embodiments of the present disclosure, when the subnet that receives the data service request lacks resources or does not support the relevant data service capabilities, the central network and / or another subnet with data service capabilities are used to process the tasks to be executed, enabling the data service to be flexibly scheduled and executed among multiple networks, improving the overall performance and resource utilization rate of the system.

[0128] Figure 12 The flowchart of another cross-network data service method provided by the embodiments of the present disclosure applied to a distributed network is shown. As Figure 12 shown, in one embodiment, the present disclosure further provides a cross-network data service method applied to a distributed network, where the distributed network includes a central network and multiple subnets; the method mainly includes the following steps: S1202. The first network element of the second target network receives the task information of the data service task sent by the first target network. The task information of the data service task is obtained by the first network element of the first target network through task orchestration in response to the data service request initiated by the data service requester. The data service task includes at least one task to be executed; S1204. The second target network processes the data service task to obtain a data service result and returns the data service result to the data service requester; where the first target network is the central network in the distributed network, and the second target network is a subnet in the distributed network; or the first target network is a subnet in the distributed network, and the second target network is the central network in the distributed network.

[0129] In one embodiment, the above S1204 that the second target network processes the data service task to obtain a data service result includes: S1204A. The first network element of the second target network selects a second network element for the data service task based on the capabilities and resource information of the second network element in the second target network, and sends the task information of the data service task to the selected second network element in the second target network; S1204B. The selected second network element in the second target network selects a target data service execution network element for each task to be executed based on the capabilities and resource information of the data service execution network element; S1204C. The selected second network element in the second target network deploys the corresponding task to be executed to the target data service execution network element to instruct the target data service execution network element to execute the corresponding task to be executed, and sends the obtained data service result to the data service requester.

[0130] In one embodiment, when the first target network is a subnet in the distributed network and the second target network is the central network in the distributed network, the above S1204 that the second target network processes the data service task to obtain a data service result includes: S1204D. The first network element of the second target network receives, through a service proxy, task information of a data service request or a data service task sent by the first network element of the first target network; S1204F. The first network element of the second target network selects a third target network based on task requirements and configuration information of multiple subnets. The third target network is another subnet in the distributed network that can provide capabilities and resources required to execute at least one to-be-executed task; S1204G. The first network element of the second target network sends, through the service proxy, the task information of the data service task to the third target network, so that the first network element in the third target network selects a corresponding second network element based on task requirements and the capabilities and resources information of the second network element in the third target network. The second network element selected in the third target network selects a target data service execution network element for each to-be-executed task based on the capabilities and resources information of the data service execution network element, deploys the corresponding to-be-executed task to the target data service execution network element to instruct the target data service execution network element to execute the corresponding to-be-executed task, and sends the obtained data service result to the data service requester.

[0131] In the embodiment of the present disclosure, through the cooperation of the first network element of the first target network and the second target network, data services can be flexibly scheduled and executed among multiple networks, improving the overall performance and resource utilization rate of the distributed network.

[0132] It should be noted that the specific implementation manner of the interaction and processing of data service requests between the second target network and the first target network is the same as the specific implementation manner in the foregoing embodiment, and will not be elaborated here.

[0133] To deepen the understanding of the embodiment of the present disclosure, the following is combined with Figures 13 - 15 for detailed description. In a distributed network architecture, a data service request can be initiated by a central network, and the control and execution of specific data service functions are responsible by subnets in the distributed network; a data service request can also be initiated by a subnet in the distributed network, and the central network executes specific tasks; or a data service request can be initiated by a subnet in the distributed network, and the central network forwards the specific task to another subnet, and the other subnet executes the specific task. The cross-network data service processes corresponding to the above three situations are as follows.

[0134] As Figure 13 shown, taking the first target network as the central network, the second target network as the subnet, the first network element as the SOF network element, and the second network element as the DSMF network element as an example for description. The cross-network data service method includes the following steps: S1301. The data service requester (which can be an NF, UE, third-party application, etc.) sends a data service request to the SOF network element in the central network. The data service request carries service types (such as high-precision positioning, imaging mapping, UAV flight supervision, environmental monitoring, etc. in sensing services), service requirements (such as sensing mode, sensing area, sensing QoS requirements, sensing data update frequency, etc.).

[0135] S1302. The SOF network element in the central network orchestrates the data service request, decomposes the data service request into multiple related tasks to be executed, maps the SLA to the QoS of the tasks to be executed, and selects the subnet of the tasks to be executed according to the configuration information of each distributed network subnet stored in the central network.

[0136] S1303. The SOF network element in the central network forwards the task information of the tasks to be executed to the SOF network element of the selected subnet through the service proxy.

[0137] S1304. The SOF network element of the selected subnet selects a suitable DSMF network element based on the task requirements and the resource and capability information table reported by the DSMF network element.

[0138] S1305. The SOF network element of the selected subnet sends the task information to the selected DSMF network element.

[0139] S1306. The selected DSMF network element in this subnet selects the target data service execution network elements of the tasks to be executed based on the resource and capability information reported by each data service execution network element, and establishes a data interaction path between the target data service execution network elements.

[0140] S1307. The selected DSMF network element in this subnet sends the task deployment information to the selected target data service execution network elements.

[0141] S1308. Each target data service execution network element and the selected DSMF network element in this subnet cooperate to execute the task.

[0142] S1309. After the task is completed, the target data service execution node returns the data service result to the data service requester.

[0143] As Figure 14 shown, taking the first target network as the subnet, the second target network as the central network, the first network element as the SOF network element, and the second network element as the DSMF network element as an example for illustration. The cross-network data service method includes the following steps: S1401. The data service demander (which can be NF, UE, third-party application, etc.) sends a data service request to the SOF network element of the subnet. The data service request carries information such as service type (such as high-precision positioning, imaging mapping, drone flight supervision, environmental monitoring, etc. in perception services), service requirements (such as perception mode, perception area, perception QoS requirements, perception data update frequency, etc.).

[0144] S1402: The SOF network element of the subnet decomposes the data service request into tasks to be executed, maps the SLA to the QoS of the tasks to be executed, estimates the resource requirements of the tasks, and finds that it lacks resources or does not support related data service capabilities.

[0145] S1403: The SOF network element of the subnet initiates a data service request to the central network through the service agent, and may also directly forward the decomposed task information to the SOF network element of the central network.

[0146] S1404. The SOF network element of the central network performs orchestration based on business logic and SLA, decomposes the data service request into tasks to be executed, generates task QoS and resource requirements, and selects a suitable DSMF network element based on the task requirements and the resource and capability information table reported by the DSMF network element of the central network.

[0147] S1405. The SOF network element of the central network sends the task information to the selected DSMF network element in the central network.

[0148] S1406. The DSMF network element selected in the central network selects a target data service execution network element for the task to be executed based on the resource and capability information reported by each data service execution network element, and establishes a data interaction path between each target data service execution network element.

[0149] S1407: The selected DSMF network element in the central network sends the task deployment information to the target data service execution network element.

[0150] S1408. Each target data service execution network element and the DSMF selected in the central network cooperate to execute the task to be executed. The execution process may involve data interaction and storage, real-time adjustment of tasks, etc.

[0151] S1409: After the task is completed, the target data service execution node returns the data service result to the data service demander.

[0152] like Figure 15 As shown, the first target network is the first subnet, the second target network is the central network, the third target network is the second subnet, the first network element is the SOF network element, and the second network element is the DSMF network element. A cross-network data service method includes the following steps: S1501. The data service demander (which can be NF, UE, third-party application, etc.) sends a data service request to the SOF network element of the first subnet. The data service request carries information such as service type (such as high-precision positioning, imaging mapping, drone flight supervision, environmental monitoring, etc. in perception services), service requirements (such as perception mode, perception area, perception QoS requirements, perception data update frequency, etc.).

[0153] S1502: The SOF network element of the first subnet decomposes the data service request into tasks to be executed, maps the SLA to the QoS of the tasks to be executed, estimates the resource requirements of the tasks, and finds that it lacks resources or does not support related data service capabilities.

[0154] S1503: The SOF network element of the first subnet initiates a data service request to the central network through the service agent, or directly forwards the decomposed task information to the SOF network element of the central network.

[0155] S1504. The central network SOF network element performs orchestration based on business logic and SLA, decomposes the data service request into tasks to be executed, generates QoS and resource requirements for the tasks to be executed, and selects other subnets based on the task requirements and resource information of each subnet. The selected subnet is called the second subnet.

[0156] S1505. The SOF network element of the central network sends the task information to the SOF network element of the second subnet through the service agent. The service agent of the central network forwarding the message here can be the same agent as that in S1503, or can be a different agent.

[0157] S1506. The SOF network element of the second subnet selects a suitable DSMF network element based on task requirements.

[0158] S1507. The SOF network element of the second subnet sends task information to the selected DSMF network element.

[0159] S1508. The DSMF network element selected by the second subnet selects a target data service execution network element for the task to be executed based on the resource and capability information reported by each data service execution network element, and establishes a data interaction path between each target data service execution network element.

[0160] S1509: The DSMF network element selected by the second subnet sends the task deployment information to the target data service execution network element.

[0161] S1510. Each target data service execution network element in the second subnet and the DSMF cooperate to execute the task. The execution process may involve data interaction and storage, real-time adjustment of tasks, etc.

[0162] After the task is completed, the target data service execution node in the second subnet returns the data service result to the data service requester.
