Telephone Charging Systems Charging CDR (Call detail Records) - PowerPoint PPT Presentation

Telephone Charging Systems • Charging • CDR (Call detail Records) • IP-DR (IP Detail Records) • Petri Noponen, 60136B

Charging • 3GPP :Charging • “A function where whereby information related to chargeable operation is formatted and transferred in order to make it possible to determine usage for which the charged party may be billed” • OMA(Open Mobile Alliance): Payment • A mechanism by which funds are moved from the customer to the merchant in exchanged for goods and/or services. It may be on a per transaction basis, or may be aggregated over a number of transactions” • Charging – separates • payment for the content • payment for the use of mobile domain (wireless bearer, mobile context: presence) • Accounting means gathering also non-charging data.

Charging • 3GPP CHARGING (Course book) • -generating • -formatting • -transferring of data records • Charging (Course book) • Generated charging info • Transformation • Normalization • Correlation of usage data • Charging Might focus also prerating -> prepaid accounts (prepaid SIM, mobile wallet) • 3GPP TS 32.240 V6.0.0 (2004-09) Release 6 • charging: a function within the telecommunications network and the associated OCS/BD components whereby information related to a chargeable event is collected, formatted, transferred and evaluated in order to make it possible to determine usage for which the charged party may be billed.

Billing • Billing process: • Bill or invoice presentation, settlements, clearing, taxation, general ledger entries • Postpaid or prepaid (IN) • Offline or online (hotbilling) • Mediation • Raw CDR- TAP file –clearing house –operators – billing system
