Definitions, symbols and abbreviations
3.1
Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [100] and the following apply.
A term defined in the present document takes precedence over the definition of the same term, if any, in
TR 21.905 [100].
chargeable event: activity utilizing telecommunication network resources and related services for:
-
user to user communication (e.g. a single call, a data communication session or a short message); or
-
user to network communication (e.g. service profile administration); or
-
inter-network communication (e.g. transferring calls, signalling, or short messages); or
-
mobility (e.g. roaming or inter-system handover); and
-
that the network operator may want to charge for.
As a minimum, a chargeable event characterizes the resource / service usage and indicates the identity of the involved
end user(s).
charged party: user involved in a chargeable event who has to pay parts or the whole charges of the chargeable event,
or a third party paying the charges caused by one or all users involved in the chargeable event, or a network operator.
charging: 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 (offline charging) or the subscriber's account balance may
be debited (online charging).
charging event: set of charging information forwarded by the CTF towards the CDF (offline charging) or towards the
OCS (online charging). Each charging event matches exactly one chargeable event.
charging function: entity inside the core network domain, subsystem or service that is involved in charging for that
domain, subsystem or service.
