Page 2 What is Mediation?  Files transfers  Decodes data that has been encoded by the ASN.1 into the internal standard format.  Validate, formatting and conversion data by mapping rule.  Aggregates partial CDR belonging to the same session by the CDR type.  Correlates different CDRs belonging to the same session.  Filters CDRs and their fields according to the systems that need charging data.  Create flexible and wide CDR for Business System Software NE 1NE 2NE n...
