1  ScopeWord‑p. 7

The present document is part of a series of Technical Specifications (TSs) that specify charging functionality and charging management in 3GPP networks. The GSM/UMTS core network charging architecture and principles are specified in TS 32.240, which provides an umbrella for other charging management documents that specify:
  • the content of the CDRs per domain and subsystem (offline charging);
  • the content of real-time charging messages per domain / subsystem (online charging);
  • the functionality of online and offline charging for those domains and subsystems;
  • the interfaces that are used in the charging framework to transfer the charging information (i.e. CDRs or charging events).
The complete document structure of the charging management TSs is defined in TS 32.240.
The present document covers all internal aspects of the Online Charging System (OCS). The document contains the architecture and functions of the OCS logical components and thereby derives the functionality of the OCS interfaces. A detailed specification of interfaces between the logical OCS components is also included. The functionality of the OCS, as described in the present document, applies to all charging domains (bearer, session and service).
The interfaces connecting to the OCS (e.g. Ro, CAP) are out of the scope of the present document.
All terms, definitions and abbreviations used in the present document, that are common across 3GPP TSs, are defined in TR 21.905. Those that are common across charging management in 3GPP domains, services, or subsystems are provided in the umbrella document TS 32.240. Finally, those items that are specific to the present document are defined exclusively in the present document.
Furthermore, requirements that govern the charging work are specified in TS 22.115.

3  Definitions, symbols and abbreviationsWord‑p. 9

3.1  Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905, TS 32.240 and the following apply:
account:
structure residing in the OCS for holding dynamic subscription data with monetary equivalence. Accounts may have balances/counters of currency or a unit type. An account can have one or more users associated with it. Examples of account type could include individual, family, corporate, etc. As opposed to bank accounts, transaction history is not necessarily kept in the OCS account data structure.
account balance:
represents the current numerical value from which service delivery decisions can be determined.
chargeable event:
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).
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 (offline charging) or the subscribers account balance may be debited (online charging).
counter:
aggregation of units of service usage or monetary units, which may be in relation to subscriber contractual terms (e.g. number of used SMS per day or number of free minutes per month). These form the basis for any type of loyalty program like discounts or bonus.
domain:
part of a communication network that provides services using a certain technology
offline charging:
charging mechanism where charging information does not affect, in real-time, the service rendered
online charging:
charging mechanism where charging information can affect, in real-time, the service rendered and therefore a direct interaction of the charging mechanism with session/service control is required
subscriber:
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 authorised to enjoy these services, and also to set the limits relative to the use that associated users make of these services.
subscription:
a subscription describes the commercial relationship between the subscriber and the service provider.
tariff:
set of parameters defining the network utilization charges for the use of a particular bearer / session / service.
