Service data flow report For independent online and offline charging, a “List of Service Data” container for the service data flow
is added at:
expiry of time limit
expiry of volume limit
expiry of unit limit
termination of service data flow
For tight interworking of online and offline charging, a “List of Service Data” container for the service
data flow is added when:
data flow is added when:
time threshold reached
volume threshold reached

unit quota exhausted
expiry of quota validity timer
termination of service data flow – re-authorization request by OCS.
S-CDR Triggers
The SGSN will use the Charging Characteristics to determine whether to activate or deactivate CDR generation. The
Charging Characteristics are also used to set the coherent chargeable event conditions (e.g. time/volume limits that
trigger CDR generation or information addition). Multiple Charging Characteristics "profiles" may be configured on the
SGSN to allow different sets of trigger values.
