Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to a control method, related equipment, and storage medium. Background Art

[0002] Services require control within the network. In fifth-generation mobile communication technology (5G) systems, the Operations, Maintenance, and Management (OAM) system is limited to large-scale, slow, and semi-static management services, and is unable to control the core network, transmission network, base stations, and terminals. There is also a lack of unified coordination and control among the core, transmission, and access networks. This results in a lack of coordination among the resources supporting a particular service when it is transmitted across the network. For example, the admission control algorithm on a base station can prevent a user from passing authentication at the base station, even if the user's needs have been authenticated by the core network. This can lead to user rejection.

[0003] In other words, in the related technologies, it is impossible to perform real-time, dynamic, and unified business control on the network. Summary of the Invention

[0116] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0117] Related technologies are unable to provide real-time, dynamic, and unified service control over the network. Currently, 5G networks support three typical services: enhanced mobile broadband (eMBB), ultra-reliable and ultra-low latency communications (URLLC), and massive machine-type communications (mMTC). Compared to 4G networks, 5G networks have expanded beyond mobile broadband (MBB) services. However, 5G networks, particularly the radio access network (RAN), remain essentially unchanged compared to 4G networks. Therefore, both 5G network evolution and next-generation networks require a leapfrog evolution.

[0118] Based on this, in various embodiments of the present application, the control center controls the network to update the service policy according to the network information.

[0119] The present application embodiment provides a control method, which is applied to a control center, such as Figure 1 As shown, the method includes:

[0120] Step 101: Obtain network information; the network information includes at least one of the following:

[0121] Business control requirements;

[0122] Business operation status report;

[0123] Control requirements for devices in the network;

[0124] Operational status reports of devices in the network;

[0125] Step 102: Based on the acquired network information, control the network to update the service policy.

[0126] The control center may also be referred to as a management center or a processing center. In actual application, the control center may be set up on an operation, maintenance and management (OAM) device (also referred to as an OAM system).

[0127] Since the control center controls the entire network, it can obtain network information through network devices.

[0128] Based on this, in one embodiment, the acquired network information comes from at least one of the following network elements:

[0129] Core network equipment;

[0130] Access network equipment;

[0131] Transmission network equipment that connects the access network and the core network.

[0132] Here, in actual application, the access network device may include a base station.

[0133] In related technologies, in fourth-generation mobile communication technology (4G) or fifth-generation mobile communication technology (5G) networks, AI technology is used in an external AI manner. That is, various information required for AI processing is reported to AI functional nodes through the network side (base station, core network) and the terminal side, thereby implementing AI-related processing outside the network element. In other words, the AI ​​functional nodes outside the network element perform data collection, processing, and AI model training, and then send the results of AI operation or the generated policy (in English, it can be expressed as policy) to the network. This poses the following insurmountable challenges:

[0134] To make AI operation results more accurate or effective, large amounts of real-time, fine-grained measurement information must be reported to an external AI center, namely, the AI ​​function node. This approach requires reporting a large amount of data to the AI ​​center, resulting in significant network transmission costs. This requires the core network, base stations, and terminals to provide additional computing and storage resources for measurement message reporting, and also increases power consumption in network and terminal devices. Therefore, both the cost and interoperability (interoperability between different vendors) of this approach make it unsuitable for commercial use in commercial networks.

[0135] 2. In this approach, the effectiveness of AI on the network depends on the accuracy of the measurement data, resulting in the AI ​​operation results or generated strategies not matching the needs of the network. Therefore, the gains brought by AI to the network cannot be reflected, and the vision of a smart network cannot be realized.

[0136] In other words, the costs and interoperability of using AI in related technologies make it impossible to apply AI technology to commercial networks; at the same time, the use of AI cannot reflect the benefits that AI technology brings to the network.

[0137] Therefore, the sixth-generation mobile communication technology (6G) network is a network with native intelligence (also known as native AI). In a 6G network with native intelligence, AI no longer simply optimizes wireless resources; it becomes an intelligent system (also known as an AI system) integrated with the core network, transmission network, and wireless access network. The 6G network needs to support services for multiple application scenarios, and only an intelligent 6G network can meet these requirements.

[0138] The digital twin (DT) system provides the fundamental operating environment for 6G's inherent intelligence, providing foundational support for AI-related processing and computing while simplifying the operational load and complexity of physical networks. In other words, the 6G digital twin system and the inherent intelligence system together comprise a series of online operations for physical network operations, including operation, maintenance, and application-oriented control computing. They become the brain of the physical network, directing every part of the physical network to deliver the services required by protocols or operators.

[0139] In summary, endogenous intelligence and digital twins have become core features of 6G networks. Therefore, endogenous intelligence and / or digital twins can be implemented by integrating intelligent and / or digital twin functions into protocol stack functions within the OAM system, core network, transport network, and access network.

[0140] Based on this, in one embodiment, the core network device has a digital twin function and / or an AI function. Among them, for the AI ​​function, it mainly includes: completing the corresponding AI processing function according to the needs of the service object (i.e., the core network device), including: generating control or generating strategies according to a certain period (such as 10ms, 100ms, or 1m, etc.). For the digital twin function, it mainly includes: twinning the various functional bodies (which can be expressed as Function in English) of the core network, that is, the digital twin function completes the online simulation of each function.

[0141] In one embodiment, the access network device has a digital twin function and / or an AI function. Among them, the AI ​​function mainly includes: completing the corresponding AI processing function according to the needs of the service object (i.e., the access network device), including: generating control or generating strategies according to a certain period (such as 10ms, 100ms or 1m, etc.). The digital twin function mainly includes: twinning the corresponding protocol stack functions of the access network, that is, the digital twin function completes the online simulation of each protocol stack function.

[0142] In one embodiment, the transmission network equipment has a digital twin function and / or an AI function. Among them, the AI ​​function mainly includes: completing the corresponding AI processing function according to the needs of the service object (i.e., the access network device), including: generating control or generating strategies according to a certain period (such as 10ms, 100ms or 1m, etc.). The digital twin function mainly includes: twinning the management and control of the transmission bandwidth of the transmission network, that is, the digital twin function completes the online simulation of bandwidth changes, transmission QoS guarantees, etc.

[0143] In one embodiment, the control center has a digital twin function and / or an AI function. Among them, for the AI ​​function, it mainly includes: generating control or generating strategies according to a certain period (such as 10ms, 100ms or 1m, etc.). For the digital twin function, it mainly includes: generating a digital twin image of the whole of each network element and terminal. Here, the generated digital twin image is a large-scale image, which mainly reflects the overall digital image of different network element levels and terminals, and depicts the overall characteristics of the network element or terminal so that it can be managed and controlled by the control center.

[0144] Here, the digital twin function can also be called a twin mirror function.

[0145] When the control center has digital twin functions and / or AI functions, the control center can control the network to update business policies based on the acquired business control requirements and / or operation status reports and through the digital twin functions and / or AI functions of the control center.

[0146] In actual applications, the network includes a control core network device. Therefore, when the control center determines, based on the acquired network information, that it is necessary to control the core network device to update the service policy, the control center can control the core network device to update the service policy based on the acquired network information. Specifically, the control center can control the core network device to perform an end-to-end QoS policy update.

[0147] The network also includes access network devices. Therefore, when the control center determines, based on the acquired network information, that it is necessary to control the access network devices to update their service policies, the control center can control the access network devices to update their service policies based on the acquired network information. Specifically, the control center can control the access network devices to update their data flow control policies and / or their air interface QoS policies.

[0148] The network also includes transmission network devices. Therefore, when the control center determines, based on the acquired network information, that it is necessary to control the transmission network devices to update service policies, the control center can control the transmission network devices to update service policies based on the acquired network information. Specifically, the control center can control the transmission network devices to update transmission bandwidth adjustment policies.

[0149] Accordingly, the embodiment of the present application also provides a control method, which is applied to a core network device, such as Figure 2 As shown, the method includes:

[0150] Step 201: Sending first information to a control center; the first information includes at least one of the following:

[0151] Business control requirements;

[0152] Business operation status report;

[0153] Equipment control requirements;

[0154] Equipment operating status report;

[0155] Step 202: Under the control of the control center, the service policy is updated; wherein the core network device has a digital twin function and / or an AI function.

[0156] In actual application, in the core network, when users apply for services or perform load balancing processing, there is a demand for service control.

[0157] Based on this, in one embodiment, sending the service control requirement to the control center includes:

[0158] Sending service control requirements to the control center during service application or load balancing processing.

[0159] In addition, in actual application, the core network equipment can also send service operation status reports and equipment operation status reports to the control center. The service operation status report may include: monitoring information received and sent by the entire end-to-end service (application layer to application layer) on the core network, the operation status of each user in the network, etc. The equipment operation status may include at least one of the following operation information:

[0160] Status information of the device's own operation;

[0161] AI software running status information;

[0162] Status information of the digital twin software body.

[0163] In actual application, the core network equipment performs end-to-end QoS policy update under the control of the control center.

[0164] Here, the status information of the device itself may include: storage space occupancy, processor usage, processor temperature, hardware alarms, various software alarms, whether it is running normally, whether it is suspended, operating system memory, processor, and peripheral monitoring reports, etc.

[0165] Accordingly, the embodiment of the present application also provides a control method, which is applied to an access network device, such as Figure 3 As shown, the method includes:

[0166] Step 301: Sending second information to the control center; the second information includes at least one of the following:

[0167] Business control requirements;

[0168] Business operation status report;

[0169] Equipment control requirements;

[0170] Equipment operating status report;

[0171] Step 302: Under the control of the control center, the service policy is updated; wherein the access network device has a digital twin function and / or an AI function.

[0172] In actual application, in the access network, the quality of receiving and sending service data packets on the wireless link is monitored, and the service needs to be controlled according to the monitored quality. For example, when the quality is relatively poor, the demand for service control is generated, and the service control demand is sent to the control center.

[0173] Based on this, in one embodiment, the access network device monitors the quality of data packets on the wireless link and sends a service control request to the control center when the monitored quality meets a first condition, wherein the first condition indicates poor quality of the wireless link. Here, the first condition can be set as needed.

[0174] In actual application, when the access network equipment adopts a centralized unit (CU) and distributed unit (DU) architecture, the CU monitors the quality of service data packets received and sent on the wireless link, and controls the service according to the monitored quality needs. For example, when the quality is relatively poor, a demand for service control is generated, thereby sending the service control demand to the control center.

[0175] In the access network, it is also necessary to monitor the quality of each data packet received and sent at the air interface. When the service needs to be controlled based on the monitored quality, for example, when the quality is relatively poor, a demand for service control is generated, and the service control demand is sent to the control center.

[0176] Based on this, in one embodiment, the quality of the data packet at the air interface is monitored; when the monitored quality meets a second condition, a service control request is sent to the control center; the second condition indicates poor quality of the air interface. Here, the second condition can be set as needed.

[0177] In actual application, when the access network equipment adopts the CU and DU architecture, the DU monitors the quality of receiving and sending data packets at the air interface, and controls the service according to the monitored quality needs. For example, when the quality is relatively poor, a demand for service control is generated, and the service control demand is sent to the control center.

[0178] In addition, in actual application, the access network equipment can also send service operation status reports and equipment operation status reports to the control center. The service operation status report may include: monitoring information received and sent by the entire end-to-end service (application layer to application layer) on the access network, the operation status of each user in the network, etc. The equipment operation status may include at least one of the following operation information:

[0179] Status information of the device's own operation;

[0180] AI software running status information;

[0181] Status information of the digital twin software body.

[0182] In actual application, the core network equipment updates the data flow control policy and / or the air interface QoS policy under the control of the control center. Specifically, when the access network equipment adopts the CU and DU architecture, the CU updates the data flow control policy under the control of the control center; the DU updates the air interface QoS policy under the control of the control center.

[0183] The embodiment of the present application also provides a control method, which is applied to a transmission network device connecting a core network and an access network, such as Figure 4 As shown, the method includes:

[0188] Equipment operating status report;

[0189] Step 402: Under the control of the control center, the service policy is updated; wherein the transmission network equipment has a digital twin function and / or an AI function.

[0190] In actual application, in the transmission network, during the reception and transmission of the carried business data packets, the quality of data packet reception or transmission (such as packet loss rate, data cache occupancy rate, data packet retention delay, etc.) on each transmission node (such as router) in the transmission network is monitored. When the service needs to be controlled according to the monitored quality, for example, when the quality is relatively poor, a demand for service control is generated, and the service control demand is sent to the control center.

[0191] Based on this, in one embodiment, sending the service control requirement to the control center includes:

[0192] monitoring the reception and / or transmission quality of data packets on at least one transmission node in the transmission network;

[0193] When the monitored quality meets a third condition, a service control requirement is sent to the control center; the third condition indicates that the quality of sending and / or receiving data packets on the transmission node is poor. Here, the third condition can be set as needed.

[0194] In addition, in actual application, the transmission network equipment can also send service operation status reports and equipment operation status reports to the control center. The service operation status report may include: monitoring information received and sent by the entire end-to-end service (application layer to application layer) on the transmission network, the operation status of each user in the network, etc. The equipment operation status may include at least one of the following operation information:

[0199] In the control method provided in the embodiment of the present application, a control center obtains network information; the network information includes at least one of the following: business control requirements; business operation status reports; control requirements of devices in the network; operation status reports of devices in the network; based on the obtained network information, the network is controlled to update business policies. In this way, through the control of the control center, real-time, dynamic, and unified business control of the entire network is achieved.

[0200] The present application will be described in further detail below in conjunction with application examples.

[0201] In this application embodiment, AI functional bodies and digital twin functional bodies are introduced into the protocol stack functional bodies introduced into the OAM system, core network, transmission network and access network systems respectively, so as to realize endogenous intelligence and endogenous digital twins.

[0203] First, the OAM system is described.

[0204] In the OAM system, AI function is one of the functions of the digital twin system. Driven by AI function, the digital twin system generates various control or management operations.

[0205] The OAM system includes:

[0206] 1. Measurement Processing: This function processes measurement information reported by the network and terminal sides. This measurement information can be based on measurement information reported by distributed intelligent functional bodies and distributed digital twins on the network and terminal sides, as well as information reported directly from the network and terminal sides on a large time scale required by the OAM system.

[0210] 5. Digital twin function: Based on the above sub-functions, the digital twin function generates a digital twin image of each network element and terminal. This digital twin image is a large-scale image, which mainly reflects the digital image of different network element levels and the terminal as a whole, and depicts the overall characteristics of the network element or terminal so that it can be managed through the OAM system.

[0211] Based on digital twin functionality, the OAM system can perform cell management (Cell Mgmt), user equipment (UE) management (UE Mgmt), new function or feature management (Feature Mgmt), functional software version management (Software Version Mgmt), and service management (Traffic Mgmt). These management functions, based on the digital twins of network elements or terminals provided by the DT system, enable large-scale or granular management, such as coordination, control, and policy delivery at the cell, terminal, or service level.

[0212] The network's capability exposure can provide corresponding capability exposure based on the various management functions of the digital twin, and realize the opening of network capabilities through the open interface (Open Interface to the Outside System). In other words, a unified open interface is provided to provide AI model training for third parties, and the successfully trained AI model can be introduced into network devices or terminals.

[0213] Next, the core network is described.

[0214] In the core network, the DT function: twins each functional body of the core network; the twin mirror function completes online simulation for each function, that is, by inputting various information such as data, processes, monitoring measurements, etc. during the operation of the functional body into the twin, realizing online simulation of the function, thereby generating pre-judgments and corresponding control. In addition, it can also provide QoS control based on the user plane function (UPF). By establishing a twin mirror function of the UPF, the characteristic information of the data packets passing through the UPF, such as the information contained in the packet header, the packet net payload length, and the pattern of packet reception from upper or lower layers, is input into the corresponding twin, generating a characterization of the QoS characteristic values ​​of the UPF data packets.

[0215] AI functions: 1. Receive and execute instructions from the AI ​​functional body in the OAM system; 2. Complete corresponding AI processing functions based on the needs of core network elements, including generating control or policies according to a certain time scale (such as 1ms, 0.5ms, 0.1ms, less than 0.1ms, etc., to generate a control or processing cycle); 3. Generate information reports that meet the needs of the AI ​​functional body in the OAM system based on the information or data processed in real time by the core network elements.

[0216] Next, the transmission network is described.

[0217] In the transmission network, AI is one of the functions of the DT system. Driven by AI, the DT system generates corresponding bandwidth control, transmission QoS guarantee, etc.

[0218] AI functions: 1. Receive and execute instructions from the AI ​​function body in the OAM system; 2. Complete the corresponding AI processing functions based on the needs of the transmission network nodes, including generating control or policies according to a certain time scale (such as 1ms, 0.5ms, 0.1ms, and less than 0.1ms, etc., to generate a control or processing cycle); 3. Generate information reports that meet the needs of the AI ​​function body in the OAM system based on the information or data processed in real time by the transmission network nodes.

[0219] DT function: Build a digital twin for transmission bandwidth control and management. Driven by AI algorithms, it enables flexible bandwidth control, routing control, and online simulation of data transmission. Specifically, it can simulate bandwidth changes and transmission QoS guarantees online by using the actual data sent and received during data transmission over the transmission network.

[0220] The transmission network includes a bandwidth allocation function: driven by the AI ​​function, the DT system dynamically allocates the bandwidth required for the transmission of one or more types of service data packets at the cell level and user level according to the instructions of the OAM system.

[0221] The transport network also includes route control functions: driven by AI functions, the DT system selects appropriate routes for data packets based on the QoS guarantee capabilities of each transmission channel.

[0222] Finally, the access network is described.

[0223] In the access network, digital twin function mirroring is performed at the Layer 3 User Plane (L3UP) (the functional body responsible for user plane data processing at Layer 3 (L3) of the Access Stratum (AS)), Radio Resource Management (RRM), Media Access Control (MAC) and Physical (PHY) layers.

[0224] The L3 UP digital twin is primarily responsible for online simulation of data processing received and sent by the access network. It generates air interface-oriented transmission strategies based on each packet's header information, payload length, and L3 UP cache status. This online simulation primarily includes data analytics and QoS analytics.

[0225] The RRM digital twin function is mainly responsible for the online simulation of wireless resource management, generating controls related to switching, flow control, QoS, etc. The edge control (Edge Ctrl) function implements AI-driven functions such as functional configuration of DUs, selection and management of different DUs, etc.

[0226] The digital twin functional body of MAC is mainly responsible for generating corresponding online simulations for different MAC functions, including the uplink channel orchestration (Uplink Orchestration) corresponding to MAC uplink scheduling (MAC UL Scheduler), the downlink channel function orchestration (Downlink Orchestration) corresponding to MAC downlink scheduling (MAC DL Scheduler), and the data flow control (Data Flow Ctrl) of the air interface corresponding to the transmission and reception of data packets, namely MAC protocol data units (MAC PDUs).

[0227] The digital twin function of PHY is mainly responsible for online simulation of physical channel processing, including channel estimation, channel model adaptation and selection, etc.

[0228] AI functions: 1. Receive and execute instructions from the AI ​​function body in the OAM system; 2. Complete the corresponding AI processing functions based on the needs of access network equipment, including generating control or policies according to a certain time scale (such as 1ms, 0.5ms, 0.1ms, less than 0.1ms, etc., to generate a control or processing cycle); 3. Generate information reports that meet the needs of the AI ​​function body in the OAM system based on the information or data processed in real time by the access network equipment.

[0229] Under the CU and DU architecture, the CU can have cloud functions, that is, the CU is deployed on the cloud platform, and the corresponding AI processing functions can run based on the cloud platform to provide the DT system with AI algorithm models, etc.

[0230] The OAM system exchanges information with the open interfaces (i.e., Open APIs) of each system. Under the unified coordination of the OAM system, each functional body completes the processing of upstream and downstream data. For example, when a UE applies for a new service, the OAM system generates the overall requirements for the core network, transmission network, and access network, as well as the interfaces for the division of labor of each network element based on the service characteristics applied for by the UE and the characteristics of such services accumulated during the operation of the system, so that the transmission network can provide a bandwidth of no less than M bps and corresponding transmission QoS guarantees, so that the core network and wireless network need to have the QoS guarantee characteristics when establishing end-to-end bearer. Based on this requirement, the AI ​​and digital twin systems of the core network, transmission network, and access network respectively generate resource support that meets the requirements based on their actual operation conditions. If they cannot be met, they need to report information to OAM in a timely manner. Here, M is an integer greater than or equal to 0.

[0231] The following combination Figure 6 Describe the interaction process between systems.

[0232] like Figure 6 As shown in the figure, the process of interaction between the systems mainly includes:

[0233] Step 601: The core network, transport network, CU, and DU perform service control at their respective levels.

[0234] Specifically, in the core network, when a new user applies for a service or performs load balancing, a demand for service control arises. Based on the user's requested service or load balancing results, the core network's AI function determines the need for end-to-end service control policy adjustments for the link (i.e., adjusting the service control policy for the entire link, i.e., the link's traffic control policy).

[0235] In the transport network, during the reception and transmission of service data packets, the quality of data packets received or transmitted (e.g., packet loss rate, data buffer occupancy, packet retention delay, etc.) at each transmission node (e.g., router) in the transport network is monitored, generating a need for service control. Specifically, based on user-level channel data volume and transmission QoS monitoring, the transport network's AI function determines the need to adjust the overall link's service control policy (i.e., the link's flow control policy).

[0236] The CU monitors the quality of each user's service data packets received and sent on the wireless link, including L3 data buffer occupancy and the rate at which data packets require retransmission, generating a need for service control. Specifically, based on each user's service detection, the CU's AI function determines whether the link's flow control policy needs to be adjusted.

[0237] The DU monitors the quality of each data packet received and sent over the air interface, including HARQ retransmissions, block error rate (BLER), the ratio of large data packets being segmented and sent, the ratio of small data packets being concatenated into large data packets, the number of times data packets are moved between internal buffers, and the applicability of dynamic QoS indicators for air interface reception and transmission, generating a need for service control. Specifically, based on the quality of each user's data received and sent over the air interface, the DU's AI function determines the need to adjust the link's flow control policy.

[0238] If it needs to be initiated through the network operation and maintenance channel, an application for business control policy update is initiated to the OAM system.

[0239] Step 602: The core network equipment, transmission network equipment, CU, and DU send a running status report (which can be expressed as Running Status Report in English) to the OAM system. This includes the monitoring information received and sent by the entire end-to-end service (application layer to application layer) on the corresponding device, the status of each user running in the network, the transmission quality assurance of the transmission network data received and sent, the status information of the device itself, or the status information of the AI ​​and / or DT software running on the device, etc. The information on the running status of the device or service can be the information data directly reported by the relevant functional body (referring to the communication-related functional bodies running on these devices, such as the Packet Data Convergence Protocol (PDCP) functional body, the Radio Resource Control (RRC) functional body or the Radio Link Control (RLC) functional body, etc.), or it can be the processed information reported by the relevant AI functional body or DT functional body on the device according to the requirements defined by the OAM system interface after processing.

[0240] Step 603: The OAM system monitors the data volume of all network services. This data volume is derived from the data volume of the core network. If end-to-end transmission channel control is required, the control policy update process is initiated, i.e., subsequent steps are executed. Specifically, the OAM system monitors the data volume transmitted by the network, and the AI ​​function of the OAM system determines whether the service control policy (i.e., flow control policy) of at least one of the core network, transmission network, and access network needs to be adjusted. Here, the data volume monitored by the OAM system includes the data volume of the core network, transmission network, access network, and terminals.

[0241] It should be noted that steps 601, 602, and 603 are executed in no particular order.

[0242] Steps 604-607: When the OAM system determines that a control policy update process needs to be initiated, it sends a service control policy update to the core network, transport network, CU, and DU respectively;

[0243] Specifically, for the core network, an end-to-end QoS policy update (ie, an end-to-end QoS control policy update) is performed. The core network can adjust corresponding QoS parameters for a specified service according to the policy and generate a new QoS indication.

[0244] For the transmission network, the transmission bandwidth control strategy is updated, including: increasing or decreasing the bandwidth of the transmission channel (logic), adjusting the data transmission service quality assurance parameters of each transmission node, etc.

[0245] For CU, the flow control policy for data reception and transmission is updated, including adjusting the flow status of data received from the core network and the flow status of data received and sent to DU.

[0246] For DU, the air interface QoS control strategy is updated, including: adjusting the MAC layer to formulate targeted HARQ mechanisms, air interface transmission and feedback mechanisms, and physical resource (physical channels, and corresponding coding / decoding, modulation / demodulation, power, control accompanying channels, etc.) arrangements for the corresponding types of services.

[0247] Step 608: The OAM system sends updates related to the AI ​​model, policy, or DT system to the core network;

[0248] Step 609: Under the triggering (ie, control) of the OAM system, a non-access stratum (NAS) signaling and a signaling for configuring the AS are generated to configure the base station (CU and / or DU) respectively.

[0249] Steps 610-611: The base station sends confirmation information to the core network; the core network generates a corresponding completion confirmation message to the OAM system.

[0250] During the system operation, the OAM system triggers the control process between the core network and the base station based on the results of the AI ​​functional body and the digital twin, namely steps 608 to 611.

[0251] As can be seen from the above description, the solution provided by this application embodiment has the following technical advantages:

[0252] 1. It has endogenous AI and digital twin protocol functions. Driven by endogenous AI, network-side functions can achieve autonomy, that is, realize automated operation;

[0253] 2. Under the unified control of OAM, AI and digital twin functions are managed and controlled in an integrated manner, achieving unified DT and AI functions across the core network, transport network, and access network.

[0254] 3. It can reduce the amount of network and OAM reporting information;

[0255] 4. Localized processing of AI and digital twin functions eliminates the need to send intermediate results of processed data to management devices, reducing the amount of transmitted data while also improving data security.
