Pre-paid service scenario
![Page 15: Billing Systems - Informatics knowledge Collection · PDF file09/04/2013 · Billing System Goals „Telephone billing systems are the largest commercial transaction processing systems](https://reader031.vdocuments.us/reader031/viewer/2022020100/5a9b4d877f8b9ad96f8dfe0e/html5/thumbnails/15.jpg)
Pre-paid billing needs
Real-time balance check and reservationReal-time billing (just after the service was provided)Online charging during the service usage(how long can client use the service)
Optional element, not always implemented
![Page 16: Billing Systems - Informatics knowledge Collection · PDF file09/04/2013 · Billing System Goals „Telephone billing systems are the largest commercial transaction processing systems](https://reader031.vdocuments.us/reader031/viewer/2022020100/5a9b4d877f8b9ad96f8dfe0e/html5/thumbnails/16.jpg)
Pre-paid billing specific issues
Traditional billing systems usually operated inbatch mode.Pre-paid billing is usually a part of a pre-paidservice platform (separate from post-paidbilling system).New generation convergent billing systemsoffered (unified pre- and post-paid).

Need For Flexibility
„Changing billing system is like replacingwings on Jumbo-Jet in mid-Atlantic”
LightReading, industry portal
New services constantly added - have to be integrated with existing billing system
Billing Mediation expansionNew tariff definition
Customers specific functionality
![Page 19: Billing Systems - Informatics knowledge Collection · PDF file09/04/2013 · Billing System Goals „Telephone billing systems are the largest commercial transaction processing systems](https://reader031.vdocuments.us/reader031/viewer/2022020100/5a9b4d877f8b9ad96f8dfe0e/html5/thumbnails/19.jpg)
Billing Mediation Expansion
Development of adapters for new networkelements
New services provided (content-based, advancedservices)Equipment from another vendor (UDR formats not compactible)Each service platform has to provide UDRs (one record per service offered)
![Page 20: Billing Systems - Informatics knowledge Collection · PDF file09/04/2013 · Billing System Goals „Telephone billing systems are the largest commercial transaction processing systems](https://reader031.vdocuments.us/reader031/viewer/2022020100/5a9b4d877f8b9ad96f8dfe0e/html5/thumbnails/20.jpg)
New Tariff Definition
Capability to rate UDRs for all types ofservicesTariff Definittion flexibility:
Charging for new servicesAdvanced charging scenarios (Cross-productdiscounts, bulk discounts, ocassional discounts)
Rule-based rating (currently state-of-the-art)
![Page 21: Billing Systems - Informatics knowledge Collection · PDF file09/04/2013 · Billing System Goals „Telephone billing systems are the largest commercial transaction processing systems](https://reader031.vdocuments.us/reader031/viewer/2022020100/5a9b4d877f8b9ad96f8dfe0e/html5/thumbnails/21.jpg)
Customer specific functionality
Each implementation is a big deal for theBilling System vendor.Each customer has a set of specificrequirements.It is not uncommon for the vendor to implement customer-specific functionalityextension (especially for big customers).Smaller vendors are more willing to expandsystem funcionality.
