IMS signaling analysis system for power switching network and method

Abstract

The invention provides an IMS signaling analysis system for a power switching network and a method. The system comprises a core signaling processing unit, a plurality of servers and a mirror image switch, the mirror image switch is a multi-layer network switch supporting a port mirror image function, signaling data of each core network element of an IMS and signaling data of an access network terminal are sent to the corresponding servers in a port mirror image mode, and each server communicates with the core signaling processing unit; core signaling processing unit is configured to filter theacquired signaling data; signaling data of a non-SIP protocol is filtered out; SIP messages can be preserved, and the message type and the message flow information of the SIP message can be determined according to the message key field, a signaling flow chart of the SIP message can be drawn according to the message type and the message flow information of the SIP message, and fault diagnosis operation and maintenance processing is carried out in combination with the signaling flow chart of the SIP message and the message key field of the SIP message.

Description

technical field [0001] The disclosure belongs to the technical field of communication signaling analysis, and in particular relates to a power switching network IMS signaling analysis system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, the administrative switching network mostly adopts the IP Multimedia Subsystem (IMS) technical system, and the administrative switching network is constantly evolving to the IMS. In addition to providing daily office voice communication services, the IMS administrative switching network also undertakes call functions in various important scenarios. First of all, the IMS administrative switching network is an important backup method for dispatching calls, and its importance is becoming more and more prominent in the power grid dispatching command communication scenario.

AI Technical Summary

Problems solved by technology

[0006] (1) Post-event simulation methods cannot fully and accurately reproduce and reflect the signaling process when a fault occurs

The way of deploying soft terminals is difficult to fully simulate the terminal status, access network switch status, data network status, and access cable status when a fault occurs

[0007] (2) The operation process is complicated, and it is difficult for general operation and maintenance personnel to master

In order to simulate the behavior of access network devices, operation and maintenance personnel need to configure soft terminals, network switches, and packet capture tools. The data configuration process is complex and error-prone

[0008] (3) Signaling process data cannot be stored centrally, and it is difficult to compare multiple analysis results

The packet capture tool can only store signaling data manually, and does not support centralized and automated storage and query methods

[0009] (4) The signaling process in the core network cannot be obtained

Core network data is invisible to the access network. For the operation and maintenance personnel of city and county companies, only part of the signaling process of the access network can be obtained through soft terminal emulation, and it is impossible to analyze the entire process of the call
