Applicable contexts |

Prerequisite features |
None |
The Set User Release Cause From Latest Event Report feature inspects the latest EventReportBCSM received by Sentinel and if possible sets the UserReleaseCause integer session state variable to a cause code value appropriate for that event report. This feature can then be followed by the Release Call and Close Dialog Feature to have that cause code included in the ReleaseCall operation sent to the MSC.
The UserReleaseCause session state variable is set depending on the eventTypeBCSM field of the latest EventReportBCSM argument:
-
for Route Select Failure:
-
if the
EventReportBCSMcontains event-specific information, then the release cause is obtained from the event-specific information; -
otherwise a default of CLASS0_NO_ROUTE_TO_DESTINATION (3) is used.
-
-
for Called Party Busy:
-
if the
EventReportBCSMcontains event-specific information, then the release cause is obtained from the event-specific information; -
otherwise a default of CLASS1_USER_BUSY (17) is used.
-
-
for No Answer:
-
a default of CLASS1_NO_ANSWER (19) is used.
-
-
for Disconnect
-
if the
EventReportBCSMcontains event-specific information, then the release cause is obtained from the event-specific information; -
otherwise a default of CLASS1_NORMAL_CALL_CLEARING (16) is used.
-
For any other case, including the absence of an EventReportBCSM operation to inspect, the UserReleaseCause session state variable is left untouched.
