DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

The main solution of the embodiment of the present application is: receiving log files reported by each network element device; determining signaling storm information based on the log files; determining a control strategy based on the signaling storm information, and sending the control strategy to the access and mobility management network element AMF, so that the AMF can perform control according to the control strategy, wherein the control strategy is a different combination of base station range and user granularity as restriction conditions.

In the related art, the method of suppressing signaling storms is mainly to suppress them by building a core network element flow control mechanism. The core network element control mechanism can control the rate limit of the interface according to the type of message received, and set the maximum rate of sending information to the surrounding network elements to protect the surrounding network elements. However, when suppressing signaling storms, the related art cannot suppress them based on specific base stations and users, resulting in damage to the services of users who use the services normally or users in low-load areas.

This application uses a signaling storm control network element to realize the discovery of signaling storms and the issuance of signaling storm suppression strategies, and controls users based on different combinations of base station range and user granularity as restriction conditions.

It should be noted that the execution subject of this embodiment can be a signaling storm control device, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a signaling storm control device capable of realizing the above functions, etc. The following takes the signaling storm control device as an example to illustrate this embodiment and the following embodiments.

Based on this, an embodiment of the present application provides a signaling storm control method, which is applied to a signaling storm control network element. Referring to FIG. 1, FIG. 1 is a flow chart of an embodiment of the signaling storm control method of the present application. The signaling storm control method includes the following steps:

Step S10, receiving log files reported by each network element device;

It should be noted that the log file refers to network logs such as statistics and alarms. The network element device refers to the wireless operation and management center network element OMC and the core network OMC. The device receives the log files reported by the wireless OMC and the core network OMC.

Step S20, determining signaling storm information based on the log file;

It is understandable that the signaling storm information refers to information used for signaling storm judgment. The device determines the presence of high-load signaling storm information through the log file.

In a first feasible implementation manner, step S20 further includes the following steps:

The log files are screened by using preset keywords to obtain target log files;

It should be noted that the preset keywords are keywords sent to the northbound interface from the policy knowledge base in the device. The device screens the network log file through the preset keywords sent to the northbound interface by the policy knowledge base to obtain the target log file, wherein the preset keywords include but are not limited to the following keywords: alarm title and text keywords, capacity indicator name and threshold, business volume indicator name and threshold, system log keywords, and signaling message volume statistics.

The target log file is judged by a preset judgment rule to obtain a judgment result;

It is understandable that the preset judgment rules are the judgment rules preset in the policy knowledge base in the device. The device sends the screened target log file to the signaling storm policy module in the device. The module makes a conditional judgment on the target log according to the signaling storm judgment rules in the policy knowledge base to determine whether there is a signaling storm phenomenon and obtain a judgment result. Among them, the policy knowledge base saves the judgment conditions and threshold settings of the signaling storm. These rules may involve the signaling volume threshold within a specific time period, the abnormal growth rate, a specific type of signaling behavior pattern, etc. The judgment rules can be manually input or completed according to the big data AI algorithm.

Based on the determination result, signaling storm information is determined.

It should be noted that the signaling storm information refers to the information of the gNodeb base station with high load. The information output by the signaling storm judgment is shown in Table 1. The device determines the judgment result. If the target log meets the signaling storm judgment rule, the device extracts the gNodeb base station information with high load. The system sends the control policy to PCF through the service interface, and adds the effective policy to the effective policy database in the device for tracking and subsequent management, and links with the signaling storm policy module to update the policy status in real time, including adding, modifying and deleting; if the target log does not meet the signaling storm judgment conditions, the device removes the control policy and deletes it from the effective policy database. The device sends the policy termination message to PCF through the service interface. The maintenance personnel query, add, delete, modify and other maintenance operations on the policy knowledge base, control policy library and effective policy database in the information storage module through the southbound interface maintenance interface.

Table 1 Signaling storm judgment output information

Southbound interface function implementation:

1. Policy knowledge base maintenance

Query: Provides an interface to query the existing policy templates, rule descriptions, etc. in the policy knowledge base.

Added: Allow uploading new policy templates or updating existing policy descriptions, supporting JSON, XML and other formats.

Deletion: supports deleting unnecessary policy templates or obsolete description documents.

Modify: Provide the specific content of the interface modification policy template, including conditions, actions, etc.

2. Management and control strategy library maintenance

Query: List all defined control policies, and support filtering by conditions (such as gNodeB, SUPI range).

Added: Add new policies to the management and control policy library through the interface, support definition of policy trigger conditions, execution actions and target ranges.

Delete: Allows deletion of policies that are no longer applicable or have expired.

Modify: Provides an interface for modifying policy details, including adjusting trigger conditions, modifying execution actions, etc.

3. Effective policy database maintenance

Query: View the list of policies that are in effect on the network in real time, including their status, effective time, etc.

Status update: Supports manually enabling or disabling a specific policy and changing its status.

Synchronous operation: Ensure that the operations of the southbound interface can be synchronized to the actual operating environment in real time to ensure that the policy takes effect immediately.

History Records: Provides an interface for querying policy operation history to facilitate auditing and troubleshooting.

The northbound interface is mainly responsible for the communication between the network management system (NMS) or business support system (such as the signaling storm control subsystem) and network devices or network elements (such as wireless base stations, core network devices). In this scenario, clear interface specifications need to be defined to ensure that the OMC can transmit data in a standardized manner. Commonly used northbound interface protocols include SNMP (Simple Network Management Protocol), RESTful API, NETCONF (Network Configuration Protocol), etc. The built-in monitoring module of the OMC periodically collects the operating status, performance indicators and alarm information of the equipment. These data include but are not limited to key indicators such as the number, type, failure rate, and processing delay of signaling messages. The data collected from the OMC needs to be converted into a format that complies with the northbound interface regulations (such as JSON or XML) and encapsulated according to a predefined structure for easy parsing by the signaling storm control device. Through the northbound interface, the OMC actively pushes the encapsulated data to the signaling storm control device. When the device receives the data, it parses the data content and can quickly identify the alarm information based on the data structure. Based on the analyzed alarm data, the device applies preset rules or algorithm models to analyze whether there are signs of signaling storms, determine the affected area, and decide what control measures to take. Based on the analysis results, the device may trigger specific strategies. At the same time, the device must also be designed with a feedback mechanism to track the effectiveness of strategy execution and make timely adjustments.

Step S30, based on the signaling storm information, determine the control strategy, and send the control strategy to the access and mobility management network element AMF, so that the AMF can perform control according to the control strategy, wherein the control strategy is a different combination of base station range and user granularity as restriction conditions.

It is understandable that the control strategy refers to a strategy for controlling the signaling storm. The device determines the strategy for controlling the signaling storm according to the signaling storm information, and sends the obtained control strategy to the AMF.

Table 2 Network element equipment and functions

In a first feasible implementation manner, step S30 further includes the following steps:

Based on the signaling storm information, query the preset strategy to determine the control strategy;

It should be noted that the device queries the control policy library in the device to generate a specific control policy based on the signaling storm information. The output information is shown in Table 2. The control policy library stores a variety of control policies, including but not limited to lowering user priority, restricting specific types of signaling, adjusting resource allocation, etc., for the signaling storm policy module to query. The most appropriate policy is selected according to the specific situation identified. The signaling storm policy module diagram is shown in Figure 2.

Connecting to the network repository function network element NRF through the service-oriented interface, and querying the policy control function network element PCF corresponding to the signaling storm information to obtain the target PCF;

It is understandable that the service-oriented port in the device initiates PCF service discovery to NRF according to the 3GPP standard, uses user-related identification information (such as SUPI, GPSI) as query parameters, and queries the PCF where the user to be controlled is located. NRF, as a centralized service discovery platform, maintains the registration information and location of all services (including PCF) in the network. After receiving the query request, NRF matches the corresponding service instance according to the parameters in the request, and returns a response containing the address of the target PCF, interface information and other necessary data, so that the network function that initiates the request can directly establish a connection with the correct PCF for subsequent policy operations or information exchange. Figure 3 is a device architecture diagram of the signaling storm control method of this application.

The target PCF is connected through the service interface, and the control policy is sent to the target PCF, so that the target PCF sends the preset trigger conditions and the control policy to the AMF.

It should be noted that the trigger condition refers to the condition for screening user information. The signaling storm policy module in the device sends the generated policy data to PCF, and PCF sends the control policy to AMF through the N7 interface, and carries a single or multiple condition combination in the gNodeb range/SUPI range/GPSI range that requires user access suppression. The N7 interface is a key communication channel between PCF and AMF, dedicated to the transmission of policy and subscription data. PCF sends the detailed information (including control conditions, range, etc.) carried by the above policy instructions to AMF through the N7 interface. As the center of access and mobility management, AMF is responsible for converting the policy from PCF into specific access control or user session management operations after receiving it. According to the content of the policy, AMF may restrict the access request of users under a specific gNodeB, a specific SUPI or GPSI range, or adjust its service characteristics, such as lowering priority, limiting bandwidth usage, etc. This policy delivery method based on conditional combination realizes precise control of network resources, helps to quickly respond to local network pressure, avoid the spread of signaling storms, and maintain overall network stability and service quality. The interaction process between AMF and PCF is shown in Figure 4.

The functions of PCF need to be enhanced:

a. Supports the definition and issuance of control policies based on a single or multiple condition combinations in the gNodeb range, SUPI range, and GPSI range.

b. Add policy trigger events, including the following 5 values:

1. Initial registration

2. Mobility registration updating

3.Periodic registration updating

4. Emergency registration

5.Handover

Five new trigger events (initial registration, mobility registration update, periodic registration update, emergency registration, and switching) are added to the PCF event management system, and clear trigger conditions and corresponding policy execution logic are defined for each event.

This embodiment provides a signaling storm control method. This embodiment first performs a signaling storm judgment on the acquired base station information, obtains a corresponding control strategy according to the judgment result, and realizes signaling storm suppression for a specific base station and a specific user.

In a feasible implementation, a signaling storm control method is provided, which is applied to AMF. The signaling storm control method further includes the following steps, referring to FIG5 , which is a flow chart of the second embodiment of the signaling storm control method of the present application:

Step S100, receiving preset trigger conditions and control strategies issued by the target PCF;

It should be noted that the device receives the preset trigger condition and the preset trigger condition sent by the target PCF.

Step S200, obtaining user information sent by the base station, and controlling the user based on the preset trigger condition and the control strategy.

It is understandable that user information refers to information when a user equipment UE logs on to a network. The device filters the user information sent by the base station and performs signaling storm control on the filtered user information.

In a feasible implementation manner, step S200 further includes the following steps:

Acquire user information sent by the base station, and filter the user information based on the received trigger condition to obtain target user information;

It should be noted that the AMF in the device receives the user information sent by the base station, and filters the user information based on the trigger conditions for the five processes of initial registration, mobility registration, periodic registration, emergency registration, and switching to obtain the target user information.

Determine the signaling storm dimension of the target user information and obtain a determination result;

It is understandable that the device determines whether the gNodeb range/SUPI range/GPSI range reported by the user during registration complies with the suppression strategy based on the target user information.

Based on the judgment result, the user is managed and controlled through the management and control strategy.

It should be noted that the device sends user rejection messages based on different combinations of gNodeb/SUPI granularity/GPSI granularity as restriction conditions for dimensions such as UDM/HSS high load, regional hotspot congestion, abnormal terminal attacks, and high network load. The AMF logic diagram is shown in Figure 6.

The following functions need to be added to AMF:

a. Supports execution of control policies based on single or multiple conditions in gNodeb range, SUPI range, and GPSI range.

b. Add policy triggering events based on the two signaling processes of REGISTERED and HANDO VER defined in the 3GPP protocol, as follows:

REGISTERED signaling process: Registration Request is used as the judgment message, and the trigger condition corresponds to Registration type (type of registration request message), as shown in Figure 7.

Switch the signaling process, the trigger condition corresponds to handover, and Namf_Communication_CreateUEContext Request is used as the judgment message.

In a feasible implementation manner, based on the judgment result, the step of controlling the user by using the control strategy includes the following steps:

Based on the judgment result, a combination of corresponding restriction conditions in the management and control strategy is determined, and based on the combination, the user is managed and controlled.

It is understandable that the AMF of the device receives policy data from the PCF and performs policy matching according to conditions such as the gNodeB range, SUPI range, and GPSI range. This requires the AMF to have the ability to parse and store policy data, and to flexibly apply logical operations (such as AND, OR) to process multiple conditional combinations. When a signaling message is received that matches a policy triggering event issued by the PCF, the corresponding policy execution logic is triggered, such as limiting the signaling rate, changing routing decisions, etc., to achieve control of specific scenarios. Figure 8 is a system logic flow chart of the signaling storm control method of this application.

In this embodiment, AMF screens users through trigger conditions to obtain user information that needs to be managed, and denies access to users who meet the management and control policies to achieve signaling storm management.

It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the signaling storm control method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

The present application also provides a signaling storm control system, which is applied to a 5G (SA) network architecture. As shown in FIG9 , the signaling storm control system includes a signaling storm control subsystem and an AMF. The signaling storm control system includes:

The signaling storm control subsystem is used to receive log files reported by each network element device; determine signaling storm information based on the log files; determine control strategies based on the signaling storm information, and send the control strategies to the access and mobility management network element AMF, so that the AMF can perform control according to the control strategies, wherein the control strategies are different combinations of base station range and user granularity as restriction conditions; connect to the target PCF through the service-oriented interface, and send the control strategies to the target PCF, so that the target PCF can send the preset trigger conditions and the control strategies to the AMF.

The AMF is used to receive the preset trigger conditions and control policies issued by the target PCF; obtain the user information sent by the base station, and manage the user based on the preset trigger conditions and the control policies, wherein the target PCF sends the preset trigger conditions and the control policies through the interface.
