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.
