gprsUsageTimeStamp

Validations ASN.1 Parent Types

This timestamp identifies call setup or changes to GPRS Service Usage.  The timestamp will only be present where it is not the same as the associated Charging 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 changeTime (GSM 12.15).

Conditionality: 

Must be present where the timestamp associated with the GPRS Service Usage occurrence is not the same as the associated Charging Timestamp.
