Mass signaling diagnosis system and method based on IMS (IP Multimedia Subsystem)

Abstract

The invention belongs to the technical field of communication, and provides an IMS (IP Multimedia Subsystem)-based massive signaling diagnosis system and method. The system comprises a service balancing device and signaling acquisition and analysis equipment, the service balancing device is used for acquiring a mirror image IP data packet of an IMS core network switch and each core network element interconnection port, taking the number of call signaling sent by signaling acquisition and analysis equipment and average processing duration as parameters based on an ant colony optimization algorithm to obtain the priority of each signaling acquisition and analysis equipment at the current moment, and balancing the priority of each signaling acquisition and analysis equipment according to the priority of each signaling acquisition and analysis equipment. Forwarding the mirror image IP data packet to corresponding signaling acquisition and analysis equipment according to a priority proportion; and the signaling acquisition and analysis equipment is used for receiving the IP data packet and filtering and screening the IP data packet to obtain an SIP protocol signaling only containing a call signaling, and then judging whether the signaling is abnormal or not according to a key field value in the SIP protocol signaling.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an IMS-based massive signaling diagnosis system and method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the administrative switching network adopts the IMS technology system, which is deployed centrally in companies at a set level, such as provincial companies. Provincial company load sharing provides real-time voice services for telephone users across the province. With the gradual migration of various cities and directly affiliated units to the IMS administrative switching network, the company's administrative office users have reached 100,000 lines, about 3 million call records per day, and about 90 million signalings are generated. The fault handling work is concentrated in the provincial company , the tr...

AI Technical Summary

Problems solved by technology

[0005] (1) It is difficult to completely reproduce the fault scenario. The causes of IMS faults are complicated, and there are a large number of sporadic faults. When there is a fault, it is impossible to dial frequently, which makes it very difficult to locate the fault, and it is difficult to meet the production needs of supporting the power grid.

[0006] (3) Signaling analysis is difficult, and the IMS switching technology protocol is complex. Each call flows through multiple core devices, generating dozens of signaling messages, involving a variety of call scenarios

Operation and maintenance personnel usually analyze each signaling message one by one, and check in detail whether the information carried by each field is abnormal, which wastes a lot of manpower and is difficult to meet the needs of rapid fault handling

[0007] (3) The speed of signaling collection is slow. Signaling collection usually adopts mirroring method, mirroring the full amount of IP data packets from the network switch to the signaling analysis device, and the operation and maintenance personnel manually or automatically screen out abnormal call signaling. Due to the huge amount of mirrored IP data packets, it takes a certain amount of time to filter them, reducing the efficiency of troubleshooting
