Method and device for realizing end-to-end correlation

Abstract

The invention provides a method and device for realizing end-to-end correlation. The method comprises the steps: A, a correlation server uses a single interface signaling call detail record (CDR) with latest time in an established data source list as a CDR1, and uses a single interface signaling CDR with latest time in an established signal pMainliat list as a CDR2; B, the correlation server judges whether a time interval between the CDR1 and the CDR2 is less than a set correlation threshold, if yes, the step C is executed, if not, the step D is executed; C, the correlation server deletes the CDR1 from the data source list, respectively places the CDR1 in the pMainliat list and the corresponding event list, then the step A is returned until reaching the set ending time; and D, the correlation server extracts the CDR2 from the pMainliat list, obtains all event lists corresponding to the CRD2, and determines the single interface signaling CDRs in all event lists as the single interface signaling CDR belonging to the same communication event with the CDR2. By adopting the invention, end-to-end real-time and full correlation of signaling can be automatically realized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for realizing end-to-end association in signaling monitoring. Background technique [0002] In signaling monitoring, the so-called end-to-end association is essentially to associate signaling messages that belong to the same communication event and are transmitted between different devices or interfaces. To achieve end-to-end association, the following effects can be achieved: [0003] 1. Facilitate end-to-end network analysis: [0004] Specifically: From the perspective of the entire network, analyze the delay distribution and call loss ratio of various communication services between devices or interfaces in the entire network, and accurately locate the equipment and cause of call loss, so as to improve maintenance and optimization work s efficiency. [0005] 2. It is convenient to analyze user behavior and user perception on the entire network: [000...

AI Technical Summary

Problems solved by technology

[0012] However, this scheme has the following defects: 1. When the signaling monitoring scope or the communication protocol of the equipment under its jurisdiction is changed, the scheme requires that the association rules in the configuration file must be added or modified in time, while network cutover, upgrade Frequently today, since network cutover and signaling monitoring system maintenance are usually in different departments, it is difficult to meet the requirement of updating association rules in a timely manner, which will have a negative impact on the success rate of association, and the configuration file is manually configured , which leads to a high probability of an incomplete configuration file

2. If there is a problem of incomplete monitoring in the live network, for example, when one or more terminals are missing from monitoring, it is difficult for the above-mentioned scheme relying on the association rules between each segment of single-interface signaling CDR to be within the monitoring range. Single-interface signaling CDRs belonging to the same communication event are all associated

That is to say, when the monitoring scope is incomplete, there is a risk that the signaling belonging to the same event within the monitoring scope cannot be completely correlated
