Description

In the network communication technology, the signaling tracking system tracks and displays the signaling related to each service in real time, and provides a function of interpreting and analyzing the corresponding signaling through the signaling tracking system, so that the operator can know the content of the signaling. , flow direction and logical flow of each business. Signaling tracking is especially important for the practical application of RFID (Radio Frequency Identification) readers. It is an important means to achieve data collection and problem location.

At present, in practical applications, when performing signaling tracking service on an RFID reader, it is necessary to input a command line, that is, to input a series of commands to perform signaling tracking on the RFID reader; and display the letter in text form. Let the tracking result; When you need to save the tracking record, the tracking record is mainly saved in txt file.

In the existing tracking signaling method, the following technical defects exist:

Defects 1. Signaling tracking by inputting a series of commands requires the operator to master the man-machine operation command, which requires high technical level of the operator, so the signaling tracking operation is inconvenient;

Defect 2: When displaying the signaling tracking result, it is displayed in plain text. The user cannot quickly perform logical analysis, filtering, statistics and other logical operations based on the tracking result, which is not convenient for users to view and analyze, especially for RFID readers. In the application scenario, the amount of data contained in the RFID reader is relatively large. Therefore, data analysis, filtering, and statistics are performed according to the tracking result in text form, which is inefficient, has a large delay, and requires a large consumption. Human and material resources;

Defect 3. When the trace record needs to be saved, the data record will be saved as a txt file. Therefore, if signal tracking needs to be turned on when a problem occurs, it is impossible to analyze a large amount of data in real time, and a large amount of data needs to be obtained from the txt file. When the txt file is opened, other people may easily see the signaling content that can reflect the internal logic of the service. Therefore, the preservation of the signaling trace record has a large security risk and the confidentiality is poor.

In this step, the database access unit 27 deletes the total signaling data capacity counter count value before the signaling message minus the number of deleted signaling messages, and the obtained difference is determined as the updated total signaling data capacity counter. Count value.

Step 811: The process processing unit 21 obtains the signaling tracking parameter from the memory, and determines whether the function of automatically saving into the signaling file is set according to the signaling tracking parameter. If yes, step 812 is performed, otherwise the process ends.

Step 812: The file reading and writing unit 28 writes the signaling message extracted in step 805 into a signaling file and saves it to the disk.

Step 813: Determine whether the number of signaling files saved in the system exceeds the set file number threshold. If yes, execute step 814; otherwise, end the process.

Step 814, the file reading and writing unit 28 deletes part of the signaling file whose storage time is earlier, and ends the process.
