Abstract

A monitoring system captures and processes messages from SS7 links, to compile call detail records (CDRs) for all interoffice call attempts. The CDRs are uploaded into a relational database. Automatic Message Accounting (AMA) records also are accumulated and uploaded to a another relational database. A data preparation operation utilizes external information to enhance the records for further processing, for example, to translate information codes in the records to textual names of originating and terminating offices. The enhanced records are loaded into a multi-dimensional database. The multi-dimensional database software facilitates analysis of the records to identify a variety of network traffic patterns. The user can automatically set up and customize studies for particular applications, for example to study traffic patterns for calls through a particular office. The multi-dimensional database also enables the presentation of information from the records in formats illustrating a variety of particular features of the traffic found in a study. For example, a report may show minutes of use for calls through an office during different hours of the day or show the other offices communicating with the office under study and the numbers of calls from each of those other offices.
