1. System for the optimization of an analysis, said system comprising a telecommunication network ( 1 ) and analysis means ( 2 ) for analyzing data associated with calls, characterized in that the analysis means ( 2 ) comprise a generic analysis mechanism ( 2 0 ), which performs an analysis using an analysis tree, but which does not understand the meaning of the data being processed by it; and one or more analysis functions ( 2 1, 2 2,..., 2 N ) which utilize the analysis mechanism ( 2 0 ) and understand the meaning of the data they are processing and are able to utilize the data obtained as a result of the analysis.
