Method for carrying out path recording and source tracing on signaling No.7 network transmitting process

Abstract

The invention belongs to a method for carrying out path recording and source tracing on a signaling No.7 network transmitting process in the field of communication. The method comprises the following steps of: initially setting an original signaling point in a transmission path record, processing a sending signaling of the original signaling point and a transmitting signaling processing of a switching signaling point; changing a signaling point parameter record of a last hop, using the changed parameter record as a current signaling point parameter and sending to a central station; starting asource tracing program in source tracing to acquire a signaling point coding value of the last hop as a new signaling point coding value, and repeatedly carrying out the step until only one record isleft in a signaling point coding parameter factor table; and judging whether a source signaling point address is a forged address or not. The invention has the characteristics of simple and clear signaling transmitting path and convenient and reliable source tracing and can be used for providing detailed original data information used for the source tracing of aggressive behaviors such as attacking an original address, and the like for the detection of network safety maintenance, malicious calls, and the like, thereby effectively improving the safety, the controllability, and the like of the network transmission of the signaling No.7.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for recording the path of the No. 7 signaling network transmission process and tracing the source according to the record. This method is especially suitable for counterfeiting the source address in the No. 7 signaling network Behavior tracking. Background technique [0002] The No. 7 signaling system (SS7) is widely used by the telecommunication network to control the transmission of information. At the same time, the No. 7 signaling network is also the supporting network of the telecommunication business, carrying almost all the information in the operation of the telecommunication network. Therefore, the No. 7 signaling network is required It has high controllability. At the same time, with the emergence of network integration, business interoperability, and various new technologies and services, there are more and more external interfaces on the No. 7...

AI Technical Summary

Problems solved by technology

Although this type of method can track the signaling of a specific call, each signaling node passing through needs to construct corresponding information and send it to the background (management center). Realize traceability and tracking, which undoubtedly greatly increases the burden on the network

[0006] Therefore, the No. 7 signaling system in the above-mentioned background technology is vulnerable to attacks such as forged source addresses, and cannot provide detailed original data information for traceability for network security maintenance or even detection of malicious calls. Poor performance and controllability, etc.
