3 Definitions, symbols and abbreviations p. 7

3.1 Definitions p. 7

For the purposes of the present document, the terms and definitions given in TS 21.905 and in TS 32.251 and the following apply:

Charging key:

information used by the online and offline charging system for rating purposes.

Charging rule:

a set of information including the service data flow filters, and the charging key, for a single service data flow (further details can be found in 5.2).

Dynamic charging rule:

Charging rule where some of the data within the charging rule (e.g. service data flow filter information) is assigned via real-time analysis, which may use dynamic application derived criteria.

FBC Policy Functions:

The charging rules may be configured in such a way to allow FBC for a certain usage that allows/disallows traffic to pass through the TPF (further details can be found in 5.8).

IP network connection:

The unique UE association with an IP network (for GPRS, APN) and the allocated IP address at the TPF.

Packet flow:

a specific user data flow carried through the TPF. A packet flow can be an IP flow.

Predefined charging rule:

A charging rule which is predefined in the TPF. A predefined charging rule is either applicable for all bearers of all users or dynamically activated for an individual bearer.

Service identifier:

An identifier for a service. The service identifier may designate an end user service, a part of an end user service or an arbitrarily formed group thereof. The service identifier provides the most detailed identification, specified for flow based charging, of a service data flow. A concrete instance of a service may be identified if additional AF information is available (further details to be found in clause 5.2).

Service data flow:

aggregate set of packet flows. In the case of GPRS, it shall be possible that a service data flow is more granular than a PDP context.

Service Data Flow Filter:

a set of filter parameters used to identify one or more of the packet flows constituting a service data flow. At least the following means for the packet flow identification shall be supported: source and destination IP address+port, transport protocol, or application protocol.
