CHARGING
The Charging function collects information related to a chargeable event from specific
network nodes, which are able to generate such kind of information. As a chargeable
event can be considered any activity utilising network resources and related services
that the operator charges for.
BILLING
The Billing function processes the records coming from the charging functional entity
according to the respective tariffs in order to calculate the charge for which the user
should be billed.
ACCOUNTING
In case of roaming the Accounting function is responsible to calculate the portion that
is due to each operator. Additionally, it is reasponsible for sharing the incoming
revenue between the players (network operators, application/service providers).
PRICING
The Pricing function determines the necessary attributes for billing and accounting
processes and defines the model that should be used for the calculation of charges
and profits.
