Method and device for discovering and positioning CSFB calling process abnormal problem

Abstract

The invention provides a method and a device for discovering and positioning a CSFB calling process abnormal problem. The method comprises steps of obtaining multiple performance indexes related to the CSFB calling process, wherein the multiple performance indexes at least comprise: CSFB calling request times, CSFB calling failing issuing times, CSFB calling successful establishment times, CSFB calling establishment refusal times, an CSFB originating call falling issuing proportion, a CSFB calling establishment success rate, failure times for establishment of a CSFB UE initial context, and failure times for correcting the CSFB UE context; and discovering and positioning the abnormal problem in the CSFB calling process through analyzing the multiple performance indexes. The method for positioning the CSFB calling process abnormal problem can formulate various indexes reflecting various stages of the CSFB calling event, can position the stage when a problem could emerge through the change of the various indexes and then can perform fast position, and provides a solution scheme to different problems by combining with signaling and a present network case.

Description

technical field [0001] The invention relates to the field of network optimization in an LTE network, in particular to a method and device for discovering and locating the abnormal problem of a CSFB calling process. Background technique [0002] CSFB is a voice service solution that falls back voice calls to the circuit switched domain in an LTE network. The abnormal judgment of the caller initiation process is often solved by the statistics of the network management network indicators and signaling tracking. For example, when the network statistical indicators related to the CSFB calling process deteriorate, it will find the network element whose indicators deteriorate, and then track the relevant information of the network element, including signaling, alarm, etc., so as to troubleshoot and solve the problem. In the existing abnormal diagnosis process of CSFB calling process, there is an obvious shortcoming: when a CSFB calling problem occurs, for the location and troubles...

AI Technical Summary

Problems solved by technology

In the existing abnormal diagnosis process of CSFB calling process, there is an obvious shortcoming: when a CSFB calling problem occurs, for the location and troubleshooting of the problem, it is impossible to directly locate the problem network element or problem signaling, and can only go back. Signaling process, troubleshooting by NE, interface, and signaling process

Although the problem can still be found and located, there is no rule to follow for each problem troubleshooting, and it completely relies on the experience of network optimization staff, resulting in long troubleshooting time and inconvenient promotion of experience.
