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.

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)
