pDPContextStartTimestamp

Validations ASN.1 Parent Types

The timestamp gives the start of the PDP context in the case where the Call Event Details (GPRS Call) represents an intermediate or last partial of a PDP context.

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 the 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’.

Optionality:

Operators may decide not to supply this information (normally this will be because it is not available from the billing system).

Conditionality:

Must be present within group

GPRS Basic Call Information

where available and Partial Type Indicator is present identifying the GPRS Call as either an intermediate or last partial (subject to optionality).
