It is understood that “first / second / third” may be interchanged in a specific order or sequence where permitted, so that the embodiments of this disclosure described herein can be implemented in an order other than that illustrated or described herein.

The terminology used herein is for the purpose of describing embodiments of this disclosure only and is not intended to be limiting of this disclosure.

[0087] Embodiments of this disclosure provide a modeling method applied to a first network device. Referring to FIG2, the method includes the following steps:

[0088] Step S201: Receive the first message sent by the second network device.

[0089] The first message includes first task information and / or second task information; the first task information indicates the modeling task of the first network device; the second task information indicates the modeling task of the terminal; the first network device, the second network device, and the terminal access the same collaborative network.

[0090] Understandably, with the simultaneous improvement of the communication and computing capabilities of networks and terminal devices, in addition to building centralized data centers (DTs) in the central cloud, lightweight distributed DTs can also be built at the edge and terminal sides. Referring to Figure 3, the model disclosed herein can be built based on a cloud-edge-device collaborative DT network architecture. This DT network architecture includes the following three DT layers:

[0091] Centralized RAN DT (CDT): A RAN region model deployed on a central cloud or edge cloud, integrating multiple sub-models to reflect the overall status of the RAN region.

[0092] Distributed RAN DT (DDT): For each base station, a radio frequency channel model, traffic model, energy consumption model, etc. are built to finely characterize the base station behavior, and the terminal model of the base station coverage area is integrated to reflect the overall status of the base station itself and the coverage area.

[0093] Terminal DT (TDT): Based on terminal characteristics, signal models, mobility models, and service experience models are constructed to reflect the actual experience of the terminal in the RAN.

[0094] Within the DT network architecture layer, there is local collaboration. DTs can connect and communicate with each other through the DT interface, which provides information transfer and interaction between DTs. CDT provides global services, is responsible for DDT monitoring and management, supports seamless DDT integration, and collaborates to complete the RAN area model construction. DDT is responsible for TDT monitoring and management, supports seamless TDT integration, and collaborates to complete the base station distributed model construction.

[0095] In practical applications, the first network device can be understood as a DDT, the second network device as a CDT, the terminal as a TDT, and the cooperative network as a DT cooperative network. When DDTs and TDTs initially connect to the DT cooperative network, the CDT is responsible for providing registration and access control services to them. The upper-layer DT evaluates the lower-layer DT's construction capabilities (comprehensive evaluation indicators across different dimensions such as communication capabilities, computing capabilities, and model building capabilities) to determine whether to select it as a cooperative node. For example, the DDT analyzes the characteristics and capabilities of the TDT, comprehensively analyzing the TDT's hardware characteristics (such as processor capabilities, computing capabilities, antenna configuration, and battery capacity), software capabilities (operating system, supported network standards), communication conditions, and terminal modeling capabilities, selecting TDTs that meet the capability requirements to connect to the DT cooperative network, and reporting this to the CDT. The CDT evaluates the DDT's computing capabilities, base station model building capabilities, and ability to seamlessly integrate other models, selecting DDTs that meet the capability requirements to connect to the DT cooperative network. CDT maintains a registry containing information about lower-level DTs, and can select DTs that meet the capability requirements to connect to the DT collaboration network, forming a collaboration group composed of CDT, DDT, and TDT.

[0096] Once the collaboration group is formed, based on network status and data processing needs, the CDT can allocate modeling tasks to each DDT via DT build requests. The DDTs then distribute the build tasks related to the TDTs within their assigned tasks to the TDTs in the coverage area. Additionally, the DDTs can also initiate DT build requests to the TDTs as needed. The first message can be understood as a DT build request.

[0097] Step S202: Send a second message to the second network device.

[0098] The second message includes a distributed model that integrates the terminal model.

[0099] Understandably, after receiving a modeling task, TDT can construct a terminal model. This terminal model can include a signal model, which, based on parameters such as the terminal's receiver sensitivity and antenna gain, simulates signal propagation path loss and multipath effects to build a signal strength prediction model. The terminal model can also include a mobility model, which combines historical movement trajectories and current location information to predict the terminal's future movement direction and speed. Furthermore, the terminal model can include a service experience model, which analyzes the network resource requirements of different service types (such as video, voice, and data) and evaluates the Quality of Service (QoS) and Quality of Experience (QoE). After receiving a modeling task, DDT can also construct a distributed model. This distributed model can include base station equipment-related models such as radio frequency channel models, traffic models, and energy-saving models.

[0100] In practical applications, TDT and DDT collaborate after completing their respective modeling tasks. DDT integrates the terminal model into the distributed model, and the integration methods include the following three:

[0101] The first method: DDT subscribes to TDT: When TDT detects a specific triggering event (such as the completion or update of the terminal model), it actively uploads the terminal model to the base station node and integrates it into the distributed model.

[0102] The second method: DDT sends an update request to TDT: When DDT finds that the performance of TDT is lower than a certain standard through evaluation, it can request the terminal model to be updated and re-reported, and then reintegrated into the distributed model.

[0103] The third type: TDT data processing capability reporting: TDT can report its data processing capabilities, including the types of data processed locally and intermediate results, and DDT assists in completing the modeling of TDT.

[0104] CDT can send subscription requests to DDT or trigger RAN area model collaborative construction when DDT's credibility index drops to a certain standard (such as when data deviation is large) through performance monitoring. DDT will upload the distributed model that integrates the terminal model to CDT, and CDT will build or update the RAN area model.

[0105] The collaboration of different Data Centers (DTs) enables the efficient construction and updating of RAN area models. Large amounts of real-time, local raw data do not need to be transmitted to the cloud for centralized construction. Instead, the communication mode between DTs and the physical network is transformed into direct communication between DTs. This allows for flexible and efficient information sharing in a distributed manner, enabling the efficient construction and updating of RAN area models.

[0106] As can be seen from the above, in this embodiment, the first network device receives a first message sent by the second network device. The first message includes first task information and / or second task information. The first task information indicates the modeling task of the first network device, and the second task information indicates the modeling task of the terminal. The first network device, the second network device, and the terminal access the same collaborative network. A second message is sent to the second network device. The second message includes a distributed model that integrates the terminal model, so that different DTs can complete the model construction through communication and cooperation, effectively avoiding latency and solving the problem in related technologies that independent centralized DTs need to spend a long time in the model construction process and cannot guarantee the real-time performance of the model.

[0107] In some embodiments of this disclosure, before receiving the first message sent by the second network device, the following steps are included:

[0108] The receiving terminal sends a third message; the third message includes the terminal's first registration information; the first registration information indicates that the terminal requests access to the cooperative network;

[0109] Send a fourth message to the second network device; the fourth message includes second registration information and / or first registration information; the second registration information instructs the first network device to request access to the cooperative network.

[0110] In practical applications, the third message can be understood as a TDT access cooperation network request; the fourth message can be understood as a DDT access cooperation network request. The CDT is responsible for providing registration and access control services to both DDT and TDT. The DDT analyzes the characteristics and capabilities of the TDT, comprehensively analyzing its hardware characteristics (such as processor capability, computing power, antenna configuration, battery capacity), software capabilities (operating system, supported network standards), communication conditions, and terminal modeling capabilities. It selects TDTs that meet the capability requirements to connect to the DT cooperation network and reports this to the CDT. The CDT evaluates the DDT's computing power, base station model building capabilities, and ability to seamlessly integrate other models, selecting DDTs that meet the capability requirements to connect to the DT cooperation network. The CDT maintains a registry containing information about lower-layer DTs and can select DTs that meet the capability requirements to connect to the DT cooperation network, forming a cooperation group composed of CDT, DDT, and TDT.

[0111] In some embodiments of this disclosure, after receiving the first message sent by the second network device:

[0112] Send a fifth message to the terminal; the fifth message includes information about the second task.

[0113] The first network device model is constructed based on the first task information.

[0114] In practical applications, after the collaborative group is formed, based on network status and data processing needs, the CDT can allocate modeling tasks to each DDT through DT construction requests. The DDT then distributes the TDT-related construction tasks within the task to the TDTs within the coverage area. Upon receiving the modeling tasks, the DDT can construct a distributed model. This distributed model can include base station equipment-related models such as radio frequency channel models, traffic models, and energy-saving models. The first network equipment model can be understood as a distributed model.

[0115] In some embodiments of this disclosure, after constructing the first network device model based on the first task information, the process includes:

[0116] Send a sixth message to the terminal; the sixth message instructs the terminal to upload the terminal model;

[0117] The receiving terminal sends a seventh message; the seventh message includes the terminal model.

[0118] In practical applications, DDT can subscribe to TDT: When TDT detects a specific triggering event (such as the completion or update of the terminal model), it proactively uploads the terminal model to the base station node and integrates it into the distributed model; the sixth message can be understood as a subscription request. DDT can also send update requests to TDT: When DDT finds that TDT's performance is below a certain standard through evaluation, it can request the update and re-upload of the terminal model, and re-integrate it into the distributed model. The sixth message can be understood as a subscription message sent by DDT to TDT, and the seventh message can be understood as a reporting message from TDT.

[0119] In some embodiments of this disclosure, after receiving the seventh message sent by the receiving terminal, the following is included:

[0120] By integrating the first network device model and the terminal model, a distributed model is obtained.

[0121] In some embodiments of this disclosure, before sending the fourth message to the second network device, the following steps are included:

[0122] Receive the eighth message sent by the second network device; the eighth message instructs the first network device to upload the distributed model.

[0123] In practical applications, CDT can send a subscription request to DDT to trigger collaborative construction of the RAN area model. DDT uploads the distributed model, which integrates the terminal model, to CDT, and CDT then constructs or updates the RAN area model. The eighth message can be understood as a subscription request sent by CDT to DDT.

[0124] In some embodiments of this disclosure, after sending the fourth message to the second network device, the process includes:

[0125] Receive a ninth message sent by the second network device; the ninth message includes the first optimization feedback of the distributed model and / or the second optimization feedback of the terminal model.

[0126] In practical applications, the DT interface transmits DT profiles (i.e., a set of models, which may involve model compression techniques), sharing model parameters, structure, and algorithms to efficiently construct and optimize RAN area models.

[0153] CDT performs multiple tasks through different lower-level DTs, enabling effective knowledge / parameter sharing. This allows DTs to learn multiple related tasks simultaneously, thereby improving the performance and generalization ability of the trained model on each task and performing global optimization. The optimization results of DDT and TDT are fed back to DDT, which can then send the optimization feedback from the terminal model to TDT. DDT and TDT adjust their own parameters and behaviors based on the feedback, forming a closed-loop optimization mechanism.

[0154] In some embodiments of this disclosure, after receiving the ninth message sent by the second network device, the process includes:

[0155] Send the tenth message to the terminal; the tenth message includes the second optimization feedback of the terminal model.

[0156] In practical applications, DDT can send optimization feedback of the terminal model to TDT.

[0157] Embodiments of this disclosure provide a modeling method applied to a second network device. Referring to FIG4, the method includes the following steps:

[0158] Step S401: Send the first message to the first network device.

[0159] The first message includes first task information and / or second task information; the first task information indicates the modeling task of the first network device; the second task information indicates the modeling task of the terminal; the first network device, the second network device, and the terminal access the same collaborative network.

[0160] In practical applications, after a collaboration group is formed, based on network status and data processing needs, the CDT can allocate modeling tasks to each DDT via DT build requests. The DDT then distributes the build tasks related to the TDT within the assigned task to the TDTs within its coverage area. Furthermore, the DDT can also initiate DT build requests to the TDT as needed. The first message can be understood as a DT build request.

[0161] Step S402: Receive the second message sent by the first network device.

[0162] The second message includes a distributed system that integrates a terminal model.

[0163] In practical applications, after receiving a modeling task, TDT can construct a terminal model. The terminal model can include a signal model, which, based on parameters such as the terminal's receiver sensitivity and antenna gain, simulates signal propagation path loss and multipath effects to build a signal strength prediction model. The terminal model can also include a mobility model, which combines historical movement trajectories and current location information to predict the terminal's future movement direction and speed. Furthermore, the terminal model can include a service experience model, analyzing the network resource requirements, QoS, and QoE of different service types (such as video, voice, and data). After receiving a modeling task, DDT can construct a distributed model. The distributed model can include base station equipment-related models such as radio frequency channel models, traffic models, and energy-saving models. After completing their respective modeling tasks, TDT and DDT collaborate, with DDT integrating the terminal model into the distributed model.

[0164] Step S403: Construct a wireless access network area model based on the distributed model.

[0165] In practical applications, CDT can send subscription requests to DDT or trigger RAN area model collaborative construction when DDT's reliability index drops to a certain standard (such as when data deviation is large) through performance monitoring. DDT will upload the distributed model that integrates the terminal model to CDT, and CDT will build or update the RAN area model.

[0166] The collaboration of different Data Centers (DTs) enables the efficient construction and updating of RAN area models. Large amounts of real-time, local raw data do not need to be transmitted to the cloud for centralized construction. Instead, the communication mode between DTs and the physical network is transformed into direct communication between DTs. This allows for flexible and efficient information sharing in a distributed manner, enabling the efficient construction and updating of RAN area models.

[0167] As can be seen from the above, in this embodiment, the first network device receives a first message sent by the second network device. The first message includes first task information and / or second task information. The first task information indicates the modeling task of the first network device, and the second task information indicates the modeling task of the terminal. The first network device, the second network device, and the terminal access the same collaborative network. A second message is sent to the second network device. The second message includes a distributed model that integrates the terminal model, so that different DTs can complete the model construction through communication and cooperation, effectively avoiding latency and solving the problem in related technologies that independent centralized DTs need to spend a long time in the model construction process and cannot guarantee the real-time performance of the model.

[0168] In some embodiments of this disclosure, before sending the first message to the first network device, the following steps are included:

[0169] The terminal receives a fourth message sent by the first network device; the fourth message includes second registration information and / or first registration information; the second registration information indicates that the first network device requests access to the collaborative network; the first registration information indicates that the terminal requests access to the collaborative network.

[0170] In practical applications, the TDT sends a request to the DDT to access the DT collaborative network, and the DDT reports this to the CDT. The CDT is responsible for providing registration and access control services to both the DDT and TDT. The DDT analyzes the characteristics and capabilities of the TDT, comprehensively analyzing its hardware characteristics (such as processor power, computing power, antenna configuration, battery capacity), software capabilities (operating system, supported network standards), communication conditions, and terminal modeling capabilities. It selects TDTs that meet the capability requirements to connect to the DT collaborative network and reports this to the CDT. The CDT evaluates the DDT's computing power, base station model building capabilities, and ability to seamlessly integrate other models, selecting DDTs that meet the capability requirements to connect to the DT collaborative network. The CDT maintains a registry containing information about lower-layer DTs and can select DTs that meet the capability requirements to connect to the DT collaborative network, forming a collaborative group consisting of CDT, DDT, and TDT.

[0171] In some embodiments of this disclosure, before receiving the second message sent by the first network device, the following steps are included:

[0172] Send the eighth message to the first network device; the eighth message instructs the first network device to upload the distributed model.

[0173] In practical applications, CDT can send a subscription request to DDT or trigger RAN area model collaborative construction when performance monitoring detects that DDT's reliability index has dropped to a certain standard (such as large data deviation). DDT uploads the distributed model integrating the terminal model to CDT, and CDT builds or updates the RAN area model. The eighth message can be understood as a subscription request sent by CDT to DDT.

[0174] In some embodiments of this disclosure, after constructing and / or a wireless access network area model based on a distributed model, the process includes:

[0175] The wireless access network area model is optimized to obtain optimization feedback; the optimization feedback includes the first optimization feedback of the distributed model and / or the second optimization feedback of the terminal model.

[0176] Send a ninth message to the first network model; the ninth message includes the first optimization feedback of the distributed model and / or the second optimization feedback of the terminal model.

[0177] In practical applications, CDT performs multiple tasks through different lower-level DTs, enabling effective knowledge / parameter sharing. This allows DTs to learn multiple related tasks simultaneously, thereby improving the performance and generalization ability of the trained model on each task and performing global optimization. The optimization results of DDT and TDT are fed back to DDT, which in turn sends the optimization feedback from the terminal model to TDT. DDT and TDT adjust their own parameters and behaviors based on the feedback, forming a closed-loop optimization mechanism. The ninth message can be understood as the optimization feedback message sent by CDT to DDT.

[0178] The embodiments of this disclosure provide a modeling method applied to a terminal. Referring to FIG5, the method includes the following steps:

[0179] Step S501: Receive a fifth message sent by the first network device; the fifth message includes second task information; the second task information indicates the modeling task of the terminal; the first network device, the second network device, and the terminal access the same collaborative network.

[0180] In practical applications, after the collaborative group is formed, based on network status and data processing needs, the CDT can allocate modeling tasks to each DDT through DT construction requests. The DDT then distributes the TDT-related construction tasks within the task to the TDTs within the coverage area. Upon receiving the modeling tasks, the DDT can construct a distributed model. This distributed model can include base station equipment-related models such as radio frequency channel models, traffic models, and energy-saving models. The first network equipment model can be understood as a distributed model.

[0181] In some embodiments of this disclosure, before receiving the fifth message sent by the first network device, the process includes:

[0182] A third message is sent to the first network device; the third message includes the terminal's first registration information; the first registration information indicates that the terminal requests access to the cooperative network.

[0183] In practical applications, the TDT sends a request to the DDT to access the DT collaborative network, and the DDT reports this to the CDT. The CDT is responsible for providing registration and access control services to both the DDT and TDT. The DDT analyzes the characteristics and capabilities of the TDT, comprehensively analyzing its hardware characteristics (such as processor power, computing power, antenna configuration, battery capacity), software capabilities (operating system, supported network standards), communication conditions, and terminal modeling capabilities. It selects TDTs that meet the capability requirements to connect to the DT collaborative network and reports this to the CDT. The CDT evaluates the DDT's computing power, base station model building capabilities, and ability to seamlessly integrate other models, selecting DDTs that meet the capability requirements to connect to the DT collaborative network. The CDT maintains a registry containing information about lower-layer DTs and can select DTs that meet the capability requirements to connect to the DT collaborative network, forming a collaborative group consisting of CDT, DDT, and TDT.

[0184] In some embodiments of this disclosure, after receiving the fifth message sent by the first network device, the process includes:

[0185] A terminal model is constructed based on the information from the second task.

[0186] In practical applications, after receiving a modeling task, TDT can construct a terminal model. The terminal model can include a signal model, which, based on parameters such as the terminal's receiver sensitivity and antenna gain, simulates signal propagation path loss and multipath effects to build a signal strength prediction model. The terminal model can also include a mobility model, which combines historical movement trajectories and current location information to predict the terminal's future movement direction and speed. Furthermore, the terminal model can include a service experience model, analyzing the network resource requirements, QoS, and QoE of different service types (such as video, voice, and data). After receiving a modeling task, DDT can construct a distributed model. The distributed model can include base station equipment-related models such as radio frequency channel models, traffic models, and energy-saving models. After completing their respective modeling tasks, TDT and DDT collaborate to integrate the terminal model into the distributed model.

[0187] In some embodiments of this disclosure, after constructing the terminal model based on the second task information, the process includes:

[0188] Receive the sixth message sent by the first network device; the sixth message instructs the terminal to upload the terminal model;

[0189] Send a seventh message to the first network device; the seventh message includes the terminal model.

[0190] In practical applications, TDT and DDT collaborate after completing their respective modeling tasks. DDT integrates the terminal model into the distributed model, and the integration methods include the following three:

[0191] The first method: DDT subscribes to TDT: When TDT detects a specific triggering event (such as the completion or update of the terminal model), it actively uploads the terminal model to the base station node and integrates it into the distributed model.

[0192] The second method: DDT sends an update request to TDT: When DDT finds that the performance of TDT is lower than a certain standard through evaluation, it can request the terminal model to be updated and re-reported, and then reintegrated into the distributed model.

[0193] The third type: TDT data processing capability reporting: TDT can report its data processing capabilities, including the types of data processed locally and intermediate results, and DDT assists in completing the modeling of TDT.

[0194] The sixth message can be understood as a subscription message sent by DDT to TDT, and the seventh message can be understood as a reporting message from TDT.

[0195] In some embodiments of this disclosure, after sending the seventh message to the first network device, the process includes:

[0196] Receive the tenth message sent by the first network device; the tenth message includes the second optimization feedback of the terminal model.

[0197] In practical applications, CDT performs multiple tasks through different lower-level DTs, enabling effective knowledge / parameter sharing. This allows DTs to learn multiple related tasks simultaneously, thereby improving the performance and generalization ability of the trained model on each task and performing global optimization. The optimization results of DDT and TDT are fed back to DDT, which can then send the optimization feedback from the terminal model to TDT. DDT and TDT adjust their own parameters and behaviors based on the feedback, forming a closed-loop optimization mechanism.

[0198] In a feasible scenario, referring to Figure 6, the model construction method of this disclosure can be implemented in the following way:

[0199] 1. The centralized node (CDT) performs registration and access control for the base station node (DDT) and terminal node (TDT).

[0200] 2. The CDT / DDT evaluation node’s construction capabilities (including communication, computing, modeling capabilities, etc.).

[0202] 4. CDT assigns modeling tasks to base station nodes based on network status and data processing requirements.

[0203] 5. Base station nodes may distribute modeling tasks related to terminal DT to terminal nodes within the coverage area.

[0204] 6. Base station / terminal DT modeling.

[0205] 7. The base station sends a DT subscription / request to the terminal.

[0206] 8. CDT discovers requirements through subscriptions or performance monitoring, triggering collaborative builds.

[0207] 9. The base station uploads the constructed or updated DDT model to the CDT.

[0208] 10. CDT integrates and updates the RAN region model.

[0209] 11. CDT performs global optimization through knowledge / parameter sharing among multiple tasks.
