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. A data preparation operation utilizes external information to enhance the records for further processing, for example, to translate release cause codes in the records to textual indications of reasons for the releases. 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 and related troubles. In particular, the processing of the enhanced CDR data can provide a variety of analytical tools and reports, using the release cause codes. For example, the analysis can indicate the number of calls to a destination that did not get through and identify by major categories the principle reasons that calls did not go through, e.g. user busy, no trunk available, etc. The analysis also can identify the element that generated the cause of the release code. For example, if there were no trunk available through a particular tandem, as indicated by the release code, the CDRs and analytical report would identify the tandem.
