modificationTimestamp

Validations ASN.1 Parent Types

The timestamp identifying when the change of HSCSD parameters occurred.  This timestamp will also represent the charging timestamp where Charge Information is present.

The time is given in the local time of the Sender PMN.  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, subitem of GSM item HSCSDParmsChange, (GSM 12.05).

Conditionality: 

Mandatory within group HSCSD Parameter Modification.
