For the purposes of the present document, the terms and definitions defined in TR 21.905, TS 32.240 and TS 22.060, and the following apply:
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
When the term/prefix is omitted, reference is made independently from the GSM or UMTS functionality.
process of apportioning charges between the Home Environment, Serving Network and Subscriber.
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).
network feature that provides the mechanisms to support operator specific services even when roaming outside HPLMN.
CAMEL subscription information:
identifies a subscriber as having CAMEL services.
activity utilizing telecommunications 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 characterises the resource / service usage and indicates the identity of the involved end user(s).
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.
a function within the telecommunications network and the associated OCS/BD components whereby information related to a chargeable event is collected, formatted and transferred in order to make it possible to determine usage for which the charged party may be billed.
Charging Data Record (CDR):
A 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 is 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.
a 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.
entity inside the core network domain, subsystem or service that is involved in charging for that domain, subsystem or service.
mechanism which directly interacts in real-time with an account and controls or monitors the charges, related to the service usage. Credit-Control is a process of: checking if credit is available, credit reservation, deduction of credit from the end user account when service is completed and refunding of reserved credit not used.
part of a communication network that provides network resources using a certain bearer technology.
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 shall be a Fully Qualified Partial CDR.
packet switched bearer and radio services for GSM and UMTS systems.
qualifier indicating that this clause or paragraph applies only to a GSM system. For multi-system cases this is determined by the current serving radio access network.
qualifier indicating that this paragraph applies only to GSM System.
qualifier indicating that this paragraph applies only to UMTS System.
change of radio access between different radio access technologies such as GSM and UMTS.
An IP transmission path of defined capacity, delay and bit error rate, etc. See TS 21.905 for the definition of bearer.
The association between a UE represented by an IPv4 address and/or an IPv6 prefix, and UE identity information, if available, and a PDN represented by a PDN ID (e.g. an APN). An IP-CAN session incorporates one or more IP-CAN bearers. Support for multiple IP-CAN bearers per IP-CAN session is IP-CAN specific. An IP-CAN session exists as long as UE IP addresses are established and announced to the IP network.
middle tier TS:
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 32.271, 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 (BD) 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.
Non-Seamless WLAN Offload (NSWO):
is a capability of routing specific IP flows over the WLAN access without traversing the EPC as defined in clause 4.1.5 of TS 23.402.
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 in which data is transferred between core network elements in packet switched mode.
CDR that provides 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 (FQPC); the second has a reduced format (RPC).
Presence Reporting Area:
An area defined within 3GPP Packet Domain for the purposes of reporting of UE presence within that area due to policy control and/or charging reasons. There are two types of Presence Reporting Area: "UE-dedicated Presence Reporting Area", and "Core Network pre-configuration Presence Reporting Area".
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 partial CDR. For 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.
Selected IP Traffic Offload (SIPTO):
Offload of selected types of IP traffic (e.g. internet traffic) towards a defined IP network close to the UE's point of attachment to the access network. SIPTO is applicable to traffic offload for the macro-cellular access network and for the H(e)NB subsystem.
A subscriber is an 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.
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.
qualifier indicating that this clause or paragraph applies only to a UMTS system. For multi-system cases this is determined by the current serving radio access network.
Unused Quota timer:
the time period without quota granted or any quota being consumed for any rating group belonging to the Gy session.
An entity, not part of the 3GPP System that uses network resources by means of a subscription.
The user may or may not be identical to the subscriber holding that subscription.
User Equipment (UE):
A device allowing a user access to network services. For the purpose of 3GPP specifications the interface between the UE and the network is the radio interface. A UE can be subdivided into a number of domains, the domains being separated by reference points. Currently defined domains are the USIM and ME Domains. The ME Domain can further be subdivided into several components showing the connectivity between multiple functional groups. These groups can be implemented in one or more hardware devices. An example of such connectivity is the TE - MT interface. Further, an occurrence of a User Equipment is an MS for GSM as defined in GSM TS 04.02 (GSM Public Land Mobile Network (PLMN) Access Reference Configuration).
