causeForTerm

Validations ASN.1 Parent Types

Indicates the reason for termination of the call where that reason is anything other than normal.

Derivation: 

GSM items CauseForTerm (GSM 12.05) and CauseForRecClosing (GSM 12.15).

Conditionality: 

Must be present within groups

where the call release is abnormal, see values below.  Where the cause for termination is normal release, i.e. value 0, then the item is not present.

Values:

                                3              Unsuccessful call attempt

                                4              Stable call abnormal termination

                                5              CAMEL initiated call release

                                20           Management intervention

 

Note that the following GSM values are not valid for use in TAP:

                                0              normal release

                                2              partial record call reestablishment

Values 4, 5 and 20 are valid within a GPRS Call context only where the call did not terminate normally.  Where partial GPRS Calls are generated then only the last partial can contain a cause for termination where appropriate.

Values 3, 4 and 5 are valid within a MOC/MTC only where the call did not terminate normally.
