A subscriber may have Charging Characteristics assigned to his subscription and/or his subscribed DNNs. Default Charging Characteristics may also be pre-provisioned on the SMF.
During UE PDU session establishment, when the SMF retrieves subscription data from the UDM, if a subscribed Charging Characteristics for the requested DNN is identified, it may override the SMF pre-provisioned Charging Characteristics.
The Charging Characteristics parameter consists of a string of 16 bits designated as Behaviours (B), freely defined by Operators, as shown in TS 32.298 [51]. Each bit corresponds to a specific charging behaviour which is configured on a per operator basis, and pointed when bit is set to "1" value.
A charging behaviour is defined as an association to a specific usage design:
One usage may consist of a set of trigger profiles associated to the PDU session in converged charging as described in the Table A.1 example:

Associated to the behaviour, the following may also be configured:
– the CHF addresses to be used by the SMF, optionaly with associated CHF instance ID(s) and/or CHF set ID(s);
– the "Default charging method" (online or offline) to be used as the default one for every PCC rules of the PDU Session;
– the PDU session charging method indicating whether the charging method for the PDU session is "offline only".
– charging service.
The "Default charging method",PDU session charging method and CHF addresses with possible associated CHF instance ID(s) and/or CHF set ID(s) configured in the applicable Charging Characteristics behaviour, are superseded by "Default charging method", PDU session charging method and CHF addresses with possible associated CHF instance ID(s) and/or CHF set ID(s) supplied by the PCF if any, during SMF interaction with the PCF at PDU session establishment, as described in TS 23.503 [202].
