Method and system for automatically obtaining session number in No. 7 signaling link

Abstract

The invention provides a method and a system for automatically obtaining a speech path number in a No.7 signaling link. The method comprises the following steps of monitoring whether request call signaling exists in the signaling link, if yes, extracting a circuit identification code in the request call signaling and recording all speech path channels managed by the signaling link; monitoring whether end call signaling corresponding to the request call signaling exists in the signaling link according to the circuit identification code, if yes, ending the recording of all speech path channels and respectively storing a recording file generated by each speech path channel; and analyzing all recording files and finding the recording file which conforms to the call voice behavior, wherein the speech path channel corresponding to the recording file is the speech path channel for this call, and the circuit identification code is the speech path number of the speech path channel. The method and the system can automatically obtain the circuit identification code corresponding to each speech path channel in the signaling link and automatically sense whether the speech path number of the speech path channel changes, so that the loss of monitoring data can be avoided.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a system for automatically obtaining a voice channel number in a No. 7 signaling link. Background technique [0002] Signaling No. 7 is classified as common channel signaling, that is, a signaling method that transmits a group of voice channel signaling on a high-speed data link in a time-division manner, and is usually used between offices. Like other inter-office signaling systems, the No. 7 signaling system is not responsible for the transmission of specific voice signals, but it is responsible for coordinating various telecommunication transmission equipment so that various telecommunication transmission equipment can accurately establish voice channels and provide users with Serve. [0003] figure 1 shows a schematic structural diagram of the No. 7 signaling system, see figure 1 As shown, the No. 7 signaling system is characterized by suppor...
