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
