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

[0017] Figure 1 This is a schematic block diagram of an embodiment of a base station ID collection and drift positioning method based on ifx in the present application. Figure 2 This is a flow chart of an embodiment of a base station ID collection and drift positioning method based on ifx of the present application.

[0018] Combination Figure 1 and Figure 2 It is understood that the method of the present application may include: Step S11: Read configuration data, the configuration data includes configuration files and configuration information, and the configuration data includes file storage directory configuration data, base station ID list configuration data, log file name configuration data, message name configuration data and packet capture duration configuration data.

[0019] Step S12: Determine whether a file storage directory exists, and if not, create a file storage directory according to the file storage directory configuration data.

[0020] Step S13: Start the packet capture process, which includes a packet capture master process and a packet capture slave process, and start the packet capture master process and the packet capture slave process at the same time. In step S13, the ifx traffic message is connected to the network port corresponding to the network port name configuration data.

[0021] The main process of packet capture includes: Step S21: Parse the ifx traffic message and generate a user dictionary, which stores base station ID information, international mobile subscriber identity code information, mobile station international subscriber directory number information, base station ID information, timestamp information and network standard information. In step S21, the ifx traffic message includes the user's international mobile subscriber identity code information, mobile station international subscriber directory number information and base station ID information.

[0022] Step S22: Determine whether the base station ID list configuration data has a value. If not, output the base station ID information to the log file corresponding to the log file name. If there is a value, output the comparison result between the base station ID information and the current base station ID list configuration data with a value to the log file corresponding to the log file name.

[0023] The packet capture process includes: Step S31: judging whether the packet capture time has been reached according to the packet capture time configuration data, and if so, stopping the packet capture process.

[0024] Step S32: Store the ifx traffic message in the file storage directory as a message file, and name the message file according to the message name configuration data.

[0025] Specifically, the program implementation steps of the method of this application are as follows: First, read the configuration file, or configuration information. The configuration information contains the following: Network port name: the name of the network port for traffic access, configurable, default enp61s0f1; Packet capture duration: the time to capture ifx traffic, configurable, default 3600s; File storage directory: the intersection for storing log files and packet capture files, configurable, default is / home; Message name: the file name for storing messages, configurable, default is ifx.pcap; Log name: the file name of the log, configurable, the default is obtain_cellID.log; Base station ID list: Base station ID list of expected mission locations, configurable, default value is [].

[0026] Next, create a directory for storing files: Create the corresponding directory according to the "File Storage Directory" in the configuration. If the directory already exists, it will not be created.

[0027] Then, start the packet capture process: According to the parameters in the configuration, the master process parses the input ifx traffic and starts the packet capture slave process; The main process steps are as follows: Parse ifx traffic packets and generate user dictionaries. The specific implementation example is as follows: { "460XXXXX": { "MSISDN" : "137XXXXXXX", "CellID" : { "29954" : ["20241110-152010", "4G"], } } } As described in the sample, the dictionary stores the following information: IMSI, MSISDN, base station ID, timestamp, network standard; Determine whether there is a value in the "Base Station ID List" in the configuration file; If there is no value, that is, no expectation, then the collected base station ID is output to the log file; Timestamp: IMSI-MSISDN-base station ID-network standard; 20241110-152010: 460XXXXX-137XXXXXXX-29954-4G; If there is a value, that is, there is an expectation, then the comparison result is output to the log file; Timestamp: IMSI-MSISDN-base station ID-network standard-NotMatch | Match; 20241110-152010:460XXXXX-137XXXXXXX-29954-4G-Match.

[0028] The steps from the process are as follows: Determine whether the packet capture time has been reached. If so, stop the packet capture program. If satisfied, stop the packet capture process; Store the message in the directory and name it according to the message name in the configuration file.

[0029] The present application provides a base station ID collection and drift positioning system based on ifx, the system uses the aforementioned method, the system is set in an X86 server, and the system may include: Configuration data module: Configuration data is set in the configuration data module, and the configuration data includes: Network port name configuration data, representing the network port name for ifx traffic access; Packet capture duration configuration data, representing the time for capturing ifx traffic; File storage directory configuration data, representing the intersection for storing log files and packet capture files; Message name configuration data, representing the file name of the stored message; Log file name configuration data, record the log file name; Base station ID list configuration data: a list of base station IDs representing the expected mission locations.

[0030] In addition, the system also includes a file storage directory module and a packet capture module. The file storage directory module is used to determine whether a file storage directory exists. If not, the file storage directory is created according to the file storage directory configuration data. The packet capture module includes a packet capture main process submodule and a packet capture slave process submodule. The packet capture main process submodule is used to execute the packet capture main process, and the packet capture slave process submodule is used to execute the packet capture slave process.

[0031] The system of this application is intended to assist in collecting base station ID information at the mission location. The base station ID is a unique identifier that identifies a mobile communication base station, and is essential for ensuring the accuracy and stability of the communication connection. In order to meet new business needs, we need to collect this base station ID information, and this system can effectively obtain it by analyzing ifx messages. When a base station ID other than the preset one appears at the mission location, that is, when a base station drift occurs, the system can promptly locate and record the new base station ID information.

[0032] The ifx message is the call record information output by the signaling parsing component after parsing the core network signaling, which contains key information such as the user's IMSI, MSISDN, and base station ID. IMSI is the International Mobile Subscriber Identity, and MSISDN is equivalent to the mobile phone number you call daily. This system runs on an X86 server, can parse and obtain the corresponding configuration information, and continuously parse the received ifx traffic. The main process is responsible for storing user information in a dictionary and outputting the collected base station ID information; at the same time, when there is an expected base station list, the system will compare and output the comparison results.

[0033] In order to fully support the collection of base station ID information and the judgment of base station drift, the system is also designed with the function of sending messages from the process. After the packet capture time is met, the system will store the corresponding message for subsequent analysis. Operation and maintenance personnel can easily obtain base station ID information or judge whether the base station has drifted by analyzing the recorded log files. In addition, if the corresponding ifx original traffic needs to be analyzed in depth, the system will automatically store it in the specified directory to provide convenience for operation and maintenance personnel.
