ChargingTimeStamp

Validations ASN.1 Parent Types

The timestamp showing the start of the Charge Information.  This item will be present where it is not the same as an associated Call Event Start Timestamp or where there is no such associated timestamp.

The time is given in the local time of the Sender PMN (or Serving Network where this is not the Sender).  There must be a UTC Time Offset Code associated with the timestamp.

Note that local time is the local time at the location of the chargeable subscriber.  Where the location is not available, as in some call forwarding scenarios, this will be a notional ‘network local time’.

Derivation:

GSM item answerTime or seizureTime (GSM 12.05).  The actual derivation will be dependent upon the charging principles used by the Sender and as defined by their IOT.

Conditionality:
