Description

Technical Field

[0001] The present invention proposes a 5G-based power network data transmission method and system, which belongs to the technical field of power network data transmission. Background Art

[0002] The technical advantages of 5G network with high speed, low latency and large bandwidth will reshape the entire society. Embedding 5G technology into different demand scenarios of vertical industries can solve the problems of collecting, transmitting and processing massive data in the development of vertical industries, and promote the transformation and upgrading of various industries. 5G private network is based on the operator's authorized spectrum, providing industry customers with safe, reliable, flexibly customized, manageable and controllable high-quality 5G network services. Among them, MEC technology conforms to the general trend of DICT development and integration, that is, deploying cloud-based computing and storage capabilities on the mobile edge network. Deploying UPF (user plane function network element of 5G core network) on MEC can realize local diversion of business data in power plant parks, so that data does not leave the park and ensure data security.

[0003] However, the existing 5G private network technology solutions have the following defects:

[0004] 1. The current operators' 5G core network is centrally deployed, including AMF, SMF, UDM and other control plane network elements. The UPF network element deployed on the dedicated MEC of the power plant park needs to open up the link of the 5G core network through the transmission network and the data bearer network. That is, the operator needs to establish a long-distance transmission network between the core room where the 5G core network is deployed and the park. If the transmission network between the park and the operator's core room fails and is interrupted, it will cause business interruption in the park's private network;

[0005] 2. Power production enterprises have a need for "network protection". During the "network protection" period, the equipment carrying the private network services related to power production needs to be isolated from the public network, that is, the physical connection between the edge side equipment and the general network side is disconnected, which generally lasts for about a month.

[0049] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0050] An embodiment of the present invention proposes a 5G-based power network data transmission system, such as Figure 1As shown, the 5G-based power network data transmission system includes a MEC mobile edge computing module, a UPF user plane function network element module (i.e., the user plane function network element of the 5G core network) and an emergency 5GC control function module; the UPF user plane function network element module is embedded in the MEC mobile edge computing module; the UPF user plane function network element module performs network data transmission with the user terminal through the emergency 5GC control function module.

[0051] Among them, the emergency 5GC control function module includes an emergency AMF function module, an emergency SMF function module and an emergency UDM function module; wherein the user terminal accesses the UPF user plane function network element module through the emergency AMF function module, the emergency SMF function module and the emergency UDM function module.

[0052] Specifically, the emergency AMF function module is used to execute the 5G core network access management function, and when the general 5G network is lost, the user terminal can perform the emergency access management function from the local emergency 5GC control function module; wherein, the management function includes the corresponding management function execution process such as user registration, user connection management and user switching.

[0053] The emergency SMF function module is used to execute the 5G core network session management function. When the general 5G network is lost, the user terminal can establish a session management function after emergency access from the local emergency 5GC control function module; wherein, the session management function includes the corresponding session management function execution processes such as the user session activation function, the session information update function and the session information deletion function.

[0054] The emergency UDM functional module is used to execute the 5G core network user contract data management function. When the general 5G network is lost, the user terminal is enabled to access the local emergency 5GC control functional module during emergency access, perform authentication, network access operations and session establishment operations on the user terminal, and provide user contract data and other processes to the emergency AMF functional module and the emergency SMF functional module.

[0055] Specifically, the UPF user plane function network element module is used to perform the 5G core network user plane forwarding function, enable the user terminal to establish a session, and perform service data forwarding between user terminals while providing normal operation of the general 5G network. At the same time, the UPF user plane function network element module is also used to forward the session and service data established by the user terminal through the local emergency 5GC control function module when the general 5G network is disconnected.

[0056] The working principle of the above technical solution is as follows: This embodiment proposes a 5G-based power network data transmission system, which integrates the emergency 5GC function on the basis of the edge UPF stationed in the park, and moves some functions of the core network control plane and user contract management functions to the network edge of the park MEC. In the scenario where the park and the general network lose connection, it provides disaster recovery capabilities for park services, ensures that the park services are not affected or recover quickly, and reduces the impact on enterprises.

[0057] The emergency 5GC control plane functions include the emergency control plane network element AMF / SMF function and the emergency user data network element UDM function; the specific functions are as follows:

[0058] Emergency AMF function, 5G core network access management function: Provides emergency access management functions for campus users from the local emergency 5G control plane when the general network is lost, including user registration, user connection management, user switching and other processes.

[0059] Emergency SMF function, 5G core network session management function: When the general network is lost, the campus users can access the local emergency 5G control plane in an emergency and establish session management functions, including user session activation, update and deletion processes.

[0060] Emergency UDM function, 5G core network user contract data management function: provides authentication of emergency access process of campus users from the local emergency 5G control plane in the case of loss of general network connection, as well as the process of providing user contract data to AMF and SMF during access and session establishment.

[0061] The UPF user plane function network element module has the 5G core network user plane forwarding function, providing campus user session establishment and service data forwarding functions under normal network conditions; and when the general network is lost, campus users can establish sessions and forward service data through the local emergency 5G control plane.

[0062] In the operation of a 5G-based power network data transmission system proposed in this embodiment, the 5G core network user plane is always in the park. When the network is normal, the general network 5G core network control plane is used; when the general network is disconnected, the park emergency 5G core network control plane is used for disaster recovery. That is, the control plane is in the upper master and lower backup mode (the general network is the main and the park is the backup).

[0063] The technical effects of the above technical scheme are as follows: the 5G-based power network data transmission system proposed in this embodiment supports inertial operation, that is, the services of steady-state users (users who continue to carry out data services without any signaling and without moving across base stations) are not affected and can be carried out continuously; emergency access is supported. If signaling occurs in the terminal, or the terminal moves across base stations to generate switching, the user resumes the service after re-registering with the emergency 5GC. At the same time, the reliability of the current 5G private network is improved, the problem of private network islands caused by transmission failures and active "network protection" in extreme cases is solved, and the stable inertial operation of the private network is guaranteed, which meets the industry needs of power production enterprises, and can support batch replication and promotion, especially with high reproducibility in the industry. On the other hand, the 5G-based power network data transmission system proposed in this embodiment is applicable to base stations in different scenarios, including 2C2B shared and 2B exclusive base stations, which greatly increases the usability of the solution, and only establishes data synchronization docking between the park UDM and the general network UDM. The park emergency 5GC control plane has no business connection with the general network 5GC control plane. At the same time, the emergency 5GC control plane is not registered with the general network NRF: the general network does not know the information and topology of the park emergency 5GC control plane. The emergency 5GC control plane does not use the general network NRF query: the park emergency 5GC control plane does not know the general network network elements and topology.

[0064] In one embodiment of the present invention, the 5G-based power network data transmission system includes two working operation scenarios, wherein the two communication transmission operation modes are as follows:

[0065] Communication transmission operation mode 1. Communication transmission operation mode of general 5G network and campus transmission under normal conditions and non-protection network;

[0066] Communication transmission operation mode 2: Communication transmission operation mode of general 5G network and campus transmission interruption or network protection.

[0067] Among them, the operation method of the general 5G network and campus transmission under normal conditions and the communication transmission operation mode of the non-protection network includes:

[0068] The user terminal accesses the campus wireless network through the 5G core network control plane of the general 5G network, and the campus wireless network uses the AMF module of the general 5G network to access the user terminal;

[0069] The AMF module of the general 5G network uses the UDM module and the SMF module of the general 5G network to process services;

[0070] The user terminal establishes a user plane session on the UPF user plane function network element module through the 5G core network user plane of the general 5G network and the SMF module of the general 5G network;

[0071] The user terminal performs 2B service operations on the UPF user plane function network element module.

[0072] At the same time, the operation method of the communication transmission operation mode of the general 5G network and the campus transmission interruption loss or network protection includes:

[0073] Screen the current user terminals to obtain steady-state users and temporary signaling user terminals; wherein the steady-state users refer to service users that continuously perform data services (will not enter the wireless idle state) and do not move across base stations (i.e., users that will not generate signaling);

[0074] Existing data services for steady-state users will continue to be unaffected;

[0075] Send the signaling sent by the temporarily generated signaling user terminal to the emergency 5GC control function module, and perform user registration and authentication through the emergency 5GC control function module;

[0076] After completing user registration and authentication, a communication connection is temporarily generated between the signaling user terminal and the UPF user plane function network element module, and 2B service operations are performed by the temporarily generated signaling user terminal on the UPF user plane function network element module.

[0077] The working principle of the above technical solution is as follows: the 5G-based power network data transmission system includes two working operation scenarios - communication transmission operation mode 1 and communication transmission operation mode 2, as follows:

[0078] Communication transmission operation mode 1. Communication transmission operation mode of general 5G network and campus transmission under normal conditions and non-protection network;

[0079] Communication transmission operation mode 2: Communication transmission operation mode of general 5G network and campus transmission interruption or network protection.

[0080] Under normal circumstances of general 5G network and campus transmission and non-protection network communication transmission operation mode, the control plane of the large network 5G core network is used: users access from the campus wireless, and the campus wireless selects the large network AMF to access users; the large network AMF selects the large network UDM and the large network SMF for business processing; the user plane of the 5G core network settled in the park is used: the large network SMF selects the campus UPF to establish a user plane session, and the campus 2B terminal performs campus 2B services in the park through the campus UPF.

[0081] In the communication transmission operation mode where the general 5G network and campus transmission are interrupted or lost, or the network is protected, the Kite solution provides two types of service disaster recovery capabilities for the campus 2B service: inertial operation and emergency access.

[0082] Specifically, inertial operation: For steady-state users, the existing data services are kept running without being affected. Definition of steady-state users: Service users that continue to carry out data services (will not enter the wireless idle state) and do not move across base stations (that is, users that do not generate signaling); such as: continuous data services at a fixed location (typical services: fixed camera video surveillance, the location remains unchanged, and video data transmission is carried out all the time).

[0083] Emergency access: For users who generate signaling (the terminal actively sends signaling, or the terminal moves across wireless base stations to generate switching signaling), due to the loss of connection with the large network, the campus wireless will send the user signaling to the campus emergency 5GC. Through the registration process, the user will resume business after re-registering with the emergency 5GC to achieve disaster recovery.

[0084] The technical effects of the above technical solution are: Communication transmission operation mode 1 (under normal circumstances and non-network protection mode)

[0085] User terminals transmit data through the 5G core network (including control plane and user plane) of the general 5G network, and use advanced network architecture and high-speed data processing capabilities to ensure the efficiency and real-time nature of data transmission. The collaborative work of the AMF (Authentication, Authorization, and Accounting Function) module, the UDM (Unified Data Management) module, and the SMF (Session Management Function) module further optimizes the business processing flow and reduces the delay of data transmission. At the same time, the close integration of the campus wireless network and the general 5G network enables user terminals to access the network stably and continue to perform data business operations, improving the continuity and stability of the business. The establishment of the UPF (User Plane Function) user plane function network element module provides user terminals with a reliable data transmission channel, ensuring the integrity and accuracy of business data. User terminals perform 2B business operations on the UPF user plane function network element module, supporting a variety of business scenarios and flexible business configurations, meeting the needs of different industries and applications.

[0086] Communication transmission operation mode 2 (interruption or network protection mode)

[0087] The current user terminals are screened, and steady-state users and temporary signaling user terminals are quickly identified, providing strong support for emergency response. The introduction of the emergency 5GC control function module enables rapid user registration and authentication in the event of network interruption or network protection, restoring the network's communication capabilities. Existing data services for steady-state users are kept unaffected, ensuring the continuity and stability of key services. The communication connection and business operations of temporary signaling user terminals are also restored in a timely manner, reducing business losses caused by network interruption or network protection. Through the emergency response mechanism and user registration and authentication process, the reliability and security of the network are improved, preventing unauthorized users from accessing the network. At the same time, this mode can also resist external attacks and network intrusions to a certain extent, protecting the security of the network and data.

[0088] In summary, the above technical solutions have achieved remarkable technical results in terms of performance indicators, including efficient data transmission, stable business continuity, flexible 2B business operations, rapid emergency response, ensuring the continuity of key businesses, and improving network reliability and security. These technical effects provide strong network support for different industries and applications, and promote the application and development of 5G technology in various fields.

[0089] An embodiment of the present invention proposes a method for transmitting power network data in a 5G-based power network data transmission system, such as Figure 2 As shown, the power network data transmission method includes:

[0090] S1. Real-time monitoring of the operating status and network protection of general 5G networks and campus transmission;

[0091] S2. When the operation status of the general 5G network and campus transmission is in a normal operation state, and the 5G network and campus transmission are in a non-network protection state, the communication transmission operation mode of the general 5G network and campus transmission under normal conditions and non-network protection is adopted; wherein, network protection refers to the network maintenance state, that is, the network is in an interrupted maintenance state at this time;

[0092] S3. When the operation status of the general 5G network and campus transmission is in an interrupted or disconnected operation state, or the 5G network and campus transmission is in a network protection state, the communication transmission operation mode of the general 5G network and campus transmission interrupted or disconnected or network protection is adopted.

[0093] Among them, the operation methods of the general 5G network and campus transmission under normal conditions and the communication transmission operation mode of the non-protection network include:

[0094] S201. The user terminal accesses the campus wireless network through the 5G core network control plane of the general 5G network, and the campus wireless network uses the AMF module of the general 5G network to access the user terminal;

[0095] S202, the AMF module of the general 5G network uses the UDM module and the SMF module of the general 5G network to process services;

[0096] S203. The user terminal establishes a user plane session on the UPF user plane function network element module through the 5G core network user plane of the general 5G network and the SMF module of the general 5G network.

[0097] S204. The user terminal performs 2B service operations on the UPF user plane function network element module.

[0098] Among them, the operation method of the communication transmission operation mode of the general 5G network and the campus transmission interruption loss or network protection includes:

[0099] S301. Screen the current user terminals to obtain steady-state users and temporary signaling user terminals; wherein the steady-state users refer to service users that continuously perform data services (will not enter a wireless idle state) and do not move across base stations (i.e., users that will not generate signaling);

[0100] S302: Keep the existing data services of the steady-state users running without being affected;

[0101] S303, sending the signaling sent by the temporarily generated signaling user terminal to the emergency 5GC control function module, and performing user registration and authentication through the emergency 5GC control function module;

[0102] S304. After completing user registration and authentication, a communication connection is temporarily generated between the signaling user terminal and the UPF user plane function network element module, and a 2B service operation is performed by the temporarily generated signaling user terminal on the UPF user plane function network element module.

[0103] The working principle of the above technical solution is as follows: the 5G-based power network data transmission system includes two working operation scenarios - communication transmission operation mode 1 and communication transmission operation mode 2, as follows:

[0104] Communication transmission operation mode 1. Communication transmission operation mode of general 5G network and campus transmission under normal conditions and non-protection network;

[0105] Communication transmission operation mode 2: Communication transmission operation mode of general 5G network and campus transmission interruption or network protection.

[0106] Under normal circumstances of general 5G network and campus transmission and non-protection network communication transmission operation mode, the control plane of the large network 5G core network is used: users access from the campus wireless, and the campus wireless selects the large network AMF to access users; the large network AMF selects the large network UDM and the large network SMF for business processing; the user plane of the 5G core network settled in the park is used: the large network SMF selects the campus UPF to establish a user plane session, and the campus 2B terminal performs campus 2B services in the park through the campus UPF.

[0107] In the communication transmission operation mode where the general 5G network and campus transmission are interrupted or lost, or the network is protected, the Kite solution provides two types of service disaster recovery capabilities for the campus 2B service: inertial operation and emergency access.

[0108] Specifically, inertial operation: For steady-state users, the existing data services are kept running without being affected. Definition of steady-state users: Service users that continue to carry out data services (will not enter the wireless idle state) and do not move across base stations (that is, users that do not generate signaling); such as: continuous data services at a fixed location (typical services: fixed camera video surveillance, the location remains unchanged, and video data transmission is carried out all the time).

[0109] Emergency access: For users who generate signaling (the terminal actively sends signaling, or the terminal moves across wireless base stations to generate switching signaling), due to the loss of connection with the large network, the campus wireless will send the user signaling to the campus emergency 5GC. Through the registration process, the user will resume business after re-registering with the emergency 5GC to achieve disaster recovery.

[0110] The technical effects of the above technical solution are: Communication transmission operation mode 1 (under normal circumstances and non-network protection mode)

[0111] User terminals transmit data through the 5G core network (including control plane and user plane) of the general 5G network, and use advanced network architecture and high-speed data processing capabilities to ensure the efficiency and real-time nature of data transmission. The collaborative work of the AMF (Authentication, Authorization, and Accounting Function) module, the UDM (Unified Data Management) module, and the SMF (Session Management Function) module further optimizes the business processing flow and reduces the delay of data transmission. At the same time, the close integration of the campus wireless network and the general 5G network enables user terminals to access the network stably and continue to perform data business operations, improving the continuity and stability of the business. The establishment of the UPF (User Plane Function) user plane function network element module provides user terminals with a reliable data transmission channel, ensuring the integrity and accuracy of business data. User terminals perform 2B business operations on the UPF user plane function network element module, supporting a variety of business scenarios and flexible business configurations, meeting the needs of different industries and applications.

[0112] Communication transmission operation mode 2 (interruption or network protection mode)

[0113] The current user terminals are screened, and steady-state users and temporary signaling user terminals are quickly identified, providing strong support for emergency response. The introduction of the emergency 5GC control function module enables rapid user registration and authentication in the event of network interruption or network protection, restoring the network's communication capabilities. Existing data services for steady-state users are kept unaffected, ensuring the continuity and stability of key services. The communication connection and business operations of temporary signaling user terminals are also restored in a timely manner, reducing business losses caused by network interruption or network protection. Through the emergency response mechanism and user registration and authentication process, the reliability and security of the network are improved, preventing unauthorized users from accessing the network. At the same time, this mode can also resist external attacks and network intrusions to a certain extent, protecting the security of the network and data.

[0126] Step 104a: using the performance reference matrix to obtain a network performance evaluation coefficient, wherein the network performance evaluation coefficient is obtained by the following formula:

[0127]

[0128] Wherein, P represents the network performance evaluation coefficient; n represents the number of units that the general 5G network has experienced; m represents the number of network performance parameters, and m=4; S σi represents the performance reference matrix corresponding to the network performance parameter matrix corresponding to the i-th unit time; w represents the weight vector corresponding to the network performance parameter; α and β represent the preset first adjustment coefficient and the second adjustment coefficient, and the value ranges of the first adjustment coefficient and the second adjustment coefficient are 0.69-0.82 and 1.13-1.34 respectively; Var(S i ) represents the variance corresponding to the i-th row vector in the network performance parameter matrix; σ(S ij) represents the data value corresponding to the i-th row and j-th column in the performance reference matrix; W represents a preset weight matrix, and is used to represent the interaction intensity and correlation between each network performance parameter and other network performance parameters; and the structure of the preset weight matrix is ​​as follows:

[0133] The working principle of the above technical solution is: collect the network performance parameters of the general 5G network in real time through specific means, including data transmission rate, network capacity occupancy ratio, network load corresponding traffic value and system resource utilization rate. The network performance parameters collected in each unit time (such as 1 second) are sorted into a matrix form, namely the network performance parameter matrix. This matrix can intuitively display the network performance parameters at each time point. The network performance parameter matrix is ​​nonlinearly transformed using the activation function to obtain the performance reference matrix. This step is to map the original network performance parameters to a new space for better subsequent analysis. The network performance evaluation coefficient is calculated by a specific formula and a preset weight matrix. This coefficient comprehensively considers the various network performance parameters and the interaction intensity and correlation between them, and can fully reflect the operation status of the network. The network performance evaluation coefficient is compared with the preset first evaluation coefficient threshold. If the evaluation coefficient is lower than the threshold, it is determined that there is an abnormal risk in the communication operation state, and a risk warning is issued to the user terminal. At the same time, the operation instructions corresponding to the communication transmission operation mode of the general 5G network and the campus transmission interruption or loss of connection or protection network are sent to the user terminal so that the user can take timely measures to deal with the risk.

[0134] The technical effect of the above technical solution is: by real-time monitoring of network performance parameters and calculating evaluation coefficients, it is possible to timely detect abnormal risks in the communication operation status and issue early warnings to users. This helps users take timely measures to avoid potential network failures or security issues. This technical solution not only takes into account the situation of a single network performance parameter, but also comprehensively considers the interaction intensity and correlation between various parameters. Therefore, it is possible to evaluate the operation status of the network more comprehensively and accurately. By timely discovering and warning of abnormal risks in the communication operation status, this technical solution helps to improve the reliability and security of the network. This is of great significance for ensuring the communication quality and data security of users. By analyzing the network performance evaluation coefficients and the situation of each network performance parameter, useful guidance can be provided for network optimization and maintenance. For example, targeted optimization and improvement can be carried out on aspects with weaker network performance to improve the overall performance of the network. At the same time, the above technical solution is designed

[0135] At the same time, by real-time collection of network performance parameters of general 5G networks (such as data transmission rate, network capacity occupancy ratio, etc.), the technical solution can realize real-time monitoring of the communication operation status. When the network performance evaluation coefficient is lower than the preset first evaluation coefficient threshold, the system can quickly determine that there is an abnormal risk in the communication operation state and issue a risk warning to the user terminal, thereby improving the reliability and stability of the communication system. The network performance parameter matrix is ​​nonlinearly transformed using the activation function to obtain the performance reference matrix. This process helps to better reflect the dynamic changes and mutual relationships of network performance parameters. By introducing the network performance evaluation coefficient, multiple network performance parameters and their interaction strength and correlation are comprehensively considered, making the performance evaluation more comprehensive and accurate. The introduction of the weight vector w allows the contribution of different network performance parameters in the performance evaluation to be reasonably adjusted, so as to better meet the needs of the actual communication system. The value range setting of the first adjustment coefficient α and the second adjustment coefficient β helps to maintain a certain flexibility and adaptability in the performance evaluation to cope with changes in different communication environments and needs. When calculating the network performance evaluation coefficient, the variance Var(Si) in the network performance parameter matrix is ​​taken into account, which helps to reflect the fluctuation of each parameter in different unit time, so as to more accurately evaluate the stability of network performance. The preset weight matrix W takes into account the interaction intensity and correlation between each network performance parameter and other parameters, which helps to more comprehensively evaluate the overall performance of network performance. This technical solution realizes real-time monitoring and early warning of communication operation status, reduces the possibility of manual intervention and misjudgment, and improves the automation and intelligence level of the communication system. When it is determined that there is an abnormal risk in the communication operation status, the system can automatically send operating instructions to the user terminal to guide the user to perform necessary operations and adjustments, thereby improving the availability of the communication system and user experience.

[0136] In summary, the technical effects of this technical solution in terms of performance indicators are mainly reflected in real-time monitoring and early warning capabilities, nonlinear transformation and performance evaluation, the introduction of weight vectors and adjustment coefficients, the consideration of variance and correlation weights, and automation and intelligence. These technical effects jointly improve the reliability and stability of the communication system, reduce the risk of communication failures, and improve user experience and satisfaction. At the same time, this technical solution realizes a comprehensive assessment of the communication operation status and abnormal risk early warning by real-time monitoring and analysis of the network performance parameters of the general 5G network. This is of great significance for improving the reliability and security of the network and guiding network optimization and maintenance.

[0147] Step 103b, comparing the network security evaluation coefficient with a preset security evaluation coefficient threshold;

[0148] Step 104b: When the network security evaluation coefficient is lower than the preset security evaluation coefficient threshold, it is determined that there are network security risks in the general 5G network, and a network security anomaly warning is issued to the user terminal.

These parameters can reflect the operating status and transmission efficiency of the network.

[0150] Calculate the network security evaluation coefficient (step 102b):

[0151] Using the monitored network security parameters (network traffic, data volume corresponding to data packet size, and data packet frequency), combined with the preset data volume reference value and security adjustment factor, the network security evaluation coefficient (K) is calculated through a specific formula.

[0152] The calculation of the safety adjustment factor (k) takes into account the standard deviation of the data volume corresponding to the network traffic and packet size, as well as the performance reference matrix impact factor (Sx). The performance reference matrix impact factor is based on the change in the module of the performance reference matrix at different unit times, as well as the correlation weight value between the data transmission rate, network capacity utilization ratio and network load corresponding to the traffic value and the system resource utilization rate. The purpose of this step is to quantify the complex network operation status into a comparable coefficient to facilitate subsequent security evaluation.

[0153] Comparison of safety evaluation coefficient with threshold value (step 103b):

[0154] The calculated network security evaluation coefficient is compared with the preset security evaluation coefficient threshold. This threshold is set according to network security requirements and historical data to determine whether the current network operation status is within the safe range.

[0155] Abnormal warning (step 104b):

[0156] If the network security evaluation coefficient is lower than the preset security evaluation coefficient threshold, it is determined that there is a network security risk in the general 5G network, and a network security abnormality warning for the user terminal is triggered. The purpose of this step is to notify the user or administrator in time so that necessary measures can be taken to deal with potential network risks.

The introduction of the security adjustment coefficient (k) and the performance reference matrix influencing factor (Sx) enables the network security evaluation coefficient to be adjusted according to the dynamic changes of the network operation status, which is more in line with the actual network security needs. By analyzing the changes in the modulus of the performance reference matrix of different unit times, as well as the correlation weight value between the data transmission rate, network capacity occupancy ratio and network load corresponding to the usage flow value and the system resource utilization rate, the technical solution can provide strong data support for network performance optimization and resource utilization. At the same time, by analyzing the changes in the modulus of the performance reference matrix of different unit times, the fluctuation of network performance can be monitored. If the change in the modulus is large, it means that the network performance may have a large fluctuation, which helps to timely discover the problem of network instability. Based on the change in the modulus of the performance reference matrix, a network stability index can be constructed to quantitatively evaluate the stability of the network. This indicator can provide intuitive network stability evaluation results for network operation and maintenance personnel. In addition, by analyzing the correlation weight values ​​between the data transmission rate, network capacity occupancy ratio and network load corresponding to the usage flow value and the system resource utilization rate, the usage of different resources and their impact on network performance can be understood. This helps to optimize resource allocation and improve resource utilization efficiency. Through real-time monitoring and analysis of network load, load balancing problems in the network can be discovered in time. By adjusting the resource allocation strategy, load balancing can be achieved to avoid network congestion and performance degradation. At the same time, based on the change trend of the model of historical performance data and performance reference matrix, the change trend of future network performance can be predicted. This helps to formulate network optimization and expansion plans in advance to ensure the stability and reliability of network performance. At the same time, it helps to timely discover and deal with network failures and potential problems, and reduce the impact of network failures on users. By analyzing the changes in the model of the performance reference matrix of different unit times and the correlation weight values ​​between relevant performance indicators, the technical solution can produce positive technical effects in network stability evaluation, resource allocation optimization, network performance prediction and early warning, and network optimization decision support. These technical effects help to improve network performance, optimize resource utilization, improve user experience and reduce network security risks. On the other hand, through real-time monitoring and analysis of network resource usage, this technical solution helps optimize network resource allocation, improve resource utilization, and reduce operating costs. The establishment of a real-time monitoring and early warning mechanism helps to promptly discover and resolve network failures and potential problems, thereby ensuring the stability and continuity of user experience. By promptly discovering and addressing network security risks, this technical solution can improve the security of general 5G networks and protect the security and privacy of user data.

[0158] In summary, the technical effects of this technical solution in terms of performance indicators are mainly reflected in real-time monitoring and early warning capabilities, accuracy of network security evaluation coefficients, network performance optimization and resource utilization, and user experience and security improvement. These technical effects together provide a strong guarantee for the stable operation of general 5G networks and user data security.

[0159] In one embodiment of the present invention, when a general 5G network and a communication transmission operation mode of campus transmission interruption or network protection are adopted, the communication operation status is monitored in real time, and when there is an abnormality in the communication operation status, an abnormality alarm is issued to the user terminal, including:

[0160] Step 201: When using a communication transmission operation mode of a general 5G network and a campus transmission interruption or loss of connection or protection network, real-time monitoring of communication operation status parameters, wherein the communication operation status parameters include the number of communication interruptions and the duration of the interruption, the communication delay rate and the communication signal strength;

[0161] Step 202: Obtain an abnormality determination coefficient using the communication interruption times and interruption duration, communication delay rate and communication signal strength;

[0162] The abnormality determination coefficient is obtained by the following formula:

[0163]

[0164] Where Q represents the abnormality determination coefficient; N represents the total number of communication interruptions; T i represents the interruption duration corresponding to the i-th communication interruption; T x Indicates the preset interruption duration reference value; T yi represents the communication delay rate corresponding to the i-th communication interruption; m represents the number of unit times of communication in the communication transmission operation mode of the general 5G network and the campus transmission interruption or protection network, and the value range of the unit time is 1min-3min; N i represents the number of interruptions that occur in the i-th unit time; P i represents the signal strength change rate corresponding to all interruptions generated in the i-th unit time; B zpi represents the average value of the communication signal strength at the communication interruption time corresponding to the i-th unit time; B ei Indicates the communication signal strength value of the i-th unit time without interruption;

[0165] Step 203: compare the abnormality determination coefficient with a preset abnormality determination coefficient threshold;

[0166] Step 204: When the abnormality determination coefficient exceeds the preset abnormality determination coefficient threshold, it is determined that there is an abnormal operation risk in the communication transmission operation mode of the general 5G network and the campus transmission interruption and loss of connection or the protection network, and an abnormal risk alarm is issued.

[0167] The working principle of the above technical solution is: in the communication transmission operation mode using the general 5G network and the campus transmission interruption loss or protection network, the key parameters of the communication status are monitored in real time, including the number of communication interruptions and the duration of the interruption, the communication delay rate and the communication signal strength. Using the communication status parameters monitored in real time (the number of communication interruptions and the duration of the interruption, the communication delay rate and the communication signal strength), the abnormality determination coefficient Q is calculated by a specific formula. This formula comprehensively considers the total number of communication interruptions, the duration of each interruption, the communication delay rate, the number of interruptions per unit time, the signal strength change rate, the average value of the communication signal strength and the signal strength value in the uninterrupted state. The calculated abnormality determination coefficient Q is compared with the preset abnormality determination coefficient threshold. If the abnormality determination coefficient Q exceeds the preset threshold, it is determined that the communication transmission operation mode has an abnormal operation risk, and an abnormal risk alarm is issued to the user terminal.

[0168] The technical effect of the above technical solution is: by real-time monitoring of communication status parameters and calculating the abnormality determination coefficient, potential problems in communication transmission operation can be discovered in time, thereby improving the stability of communication. When a communication anomaly is detected, an alarm is promptly issued to the user terminal, allowing the user to take quick measures to reduce the impact of communication failures on user services.

By improving communication stability and reducing the impact of failures, this technical solution can enhance the user experience when using general 5G networks and communication transmission modes in which campus transmission is interrupted, lost, or protected. In the event of a communication transmission interruption or abnormality, timely alarms help system administrators respond quickly and take necessary measures to ensure the security of the system.

[0169] On the other hand, by real-time monitoring of the number and duration of communication interruptions, the technical solution can timely detect and handle communication interruption problems, thereby effectively reducing the number and duration of communication interruptions. Monitoring the communication delay rate and incorporating it into the calculation of the abnormality determination coefficient can help optimize network configuration, reduce data transmission delays, and improve the real-time nature of communication. Real-time monitoring of communication signal strength and considering the signal strength change rate can help timely detect signal fluctuations or attenuation problems, so that corresponding measures can be taken to optimize and improve the stability of communication signals. By comprehensively evaluating key performance indicators such as communication interruption, delay, and signal strength, the technical solution can provide early warning of potential communication failures, thereby reducing the communication failure rate. Through real-time monitoring of communication status, network administrators can more accurately understand the use of network resources, thereby optimizing resource allocation and improving the utilization of network resources. By reducing communication interruptions and delays and optimizing signal strength, the technical solution helps to improve the network throughput, that is, the amount of data successfully transmitted per unit time. By real-time monitoring of communication status parameters, the technical solution can timely detect and handle potential security threats, such as malicious attacks, network intrusions, etc., thereby enhancing the security of the system. In the event of communication transmission interruption or abnormality, timely alarm and response mechanisms can help improve the system's emergency response capabilities and reduce security risks.

[0170] In summary, this technical solution realizes the real-time monitoring and abnormal alarm functions of the communication transmission operation mode by real-time monitoring of communication status parameters and calculating the abnormality determination coefficient, thereby improving the stability and security of communication, optimizing network management, and enhancing user experience. At the same time, the technical effects of this technical solution in terms of performance indicators are mainly reflected in the improvement of communication stability, optimization of communication quality, improvement of network efficiency, improvement of user experience, and enhancement of system security.
