For the purposes of the present document, the terms and definitions given in TR 21.905
, TS 32.240
, TS 23.246
and the following apply:
2G- / 3G-:
prefixes 2G- and 3G- refer to functionality that supports only GSM or UMTS, respectively, e.g. 2G SGSN refers only to the GSM functionality of an SGSN.
process of apportioning charges between the Home Environment, Serving Network and Subscriber.
Advice of Charge (AoC):
real-time display of the network utilization charges incurred by the Mobile Station (MS). The charges are displayed in the form of charging units. If a unit price is stored by the MS then the display may also include the equivalent charge in the home currency.
combination of one or more services, both basic and supplementary, together with a number of other charging relevant parameters to define a customized service for the purpose of Advice of Charge (AoC).
function whereby CDRs generated by the charging function(s) are transformed into bills requiring payment.
Billing Domain (BD):
part of the operator network, which is outside the core network, that receives and processes CDR files from the core network charging functions. It includes functions that can provide billing mediation and billing or other (e.g. statistical) end applications. It is only applicable to offline charging (see "Online Charging System" for equivalent functionality in online charging).
activity utilizing telecommunications network infrastructure 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.
user involved in a chargeable event that 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.
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 subscribers account balance may be debited (online charging).
Charging Data Record (CDR):
formatted collection of information about a chargeable event (e.g. time of call set-up, duration of the call, amount of data transferred, etc.) for use in billing and accounting. For each party to be charged for parts of or all charges of a chargeable event a separate CDR shall be generated, i.e. more than one CDR may be generated for a single chargeable event, e.g. because of its long duration, or because more than one charged party is to be charged.
entity inside the core network domain, subsystem or service that is involved in charging for that domain, subsystem or service
Fully Qualified Partial CDR (FQPC):
partial CDR that contains a complete set of the fields specified in the present document. This includes all the mandatory and conditional fields as well as those fields that the PLMN operator has provisioned to be included in the CDR. The first Partial CDR is a FQPC.
packet switched bearer and radio services for GSM and UMTS systems.
GPRS protocol used for CDR transport. It is derived from GTP with enhancements to improve transport reliability necessary for CDRs.
change of radio access between different radio access technologies such as GSM and UMTS.
middle tier TS:
near real time:
term used for the 3GPP charging TSs that specify the domain / subsystem / service specific, online and offline, charging functionality.
These are all the TSs in the numbering range from TS 32.250 to TS 32.27x, e.g. TS 32.250
for the CS domain, or TS 32.270
for the MMS service. Currently, there is only one "tier 1" TS in 3GPP, which is TS 32.240
that specifies the charging architecture and principles. Finally, there are a number of top tier TSs in the 32.29x numbering range ( ff) that specify common charging aspects such as parameter definitions, encoding rules, the common billing domain interface or common charging applications.
near real time charging and billing information is to be generated, processed, and transported to a desired conclusion in less than one (1) minute.
charging mechanism where charging information does not affect, in real-time, the service rendered.
charging mechanism where charging information can affect, in real-time, the service rendered and therefore a direct interaction of the charging mechanism with bearer/session/service control is required.
Online Charging System (OCS):
the entity that performs real-time Credit-Control. Its functionality includes transaction handling, rating, online correlation and management of subscriber account balances.
packet switched domain:
domain within GSM / UMTS in which data is transferred in packet switched mode. Corresponds to the term "GPRS".
CDR that provides charging information on part of a subscriber session. A long session may be covered by several partial CDRs. Two formats are considered for Partial CDRs. One that contains all of the necessary fields; the second has a reduced format.
real time charging and billing information is to be generated, processed, and transported to a desired conclusion in less than one (1) second.
Reduced Partial CDR (RPC):
partial CDRs that only provide mandatory fields and information regarding changes in the session parameters relative to the previous CDR.
EXAMPLE: Location information is not repeated in these CDRs if the subscriber did not change its location.
payment of amounts resulting from the accounting process.
entity (associated with one or more users) that is engaged in a subscription with a service provider. The subscriber is allowed to subscribe and unsubscribe services, to register a user or a list of users authorized to enjoy these services, and also to set the limits relative to the use that associated users make of these services.
connection that reaches the communication or data transfer phase e.g. the "answered" state for speech connections. All other connection attempts are regarded as unsuccessful.
part of one (calendar) day during which a particular tariff is applied. Defined by the time at which the period commences (the switch-over time) and the tariff to be applied after switch-over.
set of parameters defining the network utilization charges for the use of a particular bearer / session / service.
