This feature uses information from the incoming TCAP message request or Sh Push Notification Result and sets the plan ID in the Sentinel selection key in Session State field. The plan ID affects which features will run for the call on the current AS instance.

Statistics

IPSMGWDetermineSessionPlan statistics are tracked by the sentinel.ipsmgw SBB and can be found under the following parameter set in REM:
SLEE-Usage → sentinel.ipsmgw service → sentinel.ipsmgw SBB → feature → IPSMGWDetermineSessionPlan
or with rhino-stats:
"SLEE-Usage.Services.ServiceID[name=sentinel.ipsmgw,vendor=OpenCloud,version=4.1].SbbID[name=sentinel.ipsmgw,vendor=OpenCloud,version=4.1].feature.IPSMGWDetermineSessionPlan"

Incremented when the trigger is a Sh UEIPReachability PNR

 
ReceivedUnknownACN

ReceivedUnknownTrigger

Incremented when the trigger is not TCAP OpenRequest

Configuration

The feature has no configuration.

Behaviour

The feature checks if the trigger message is a TCAP OpenRequest message or a Sh UEReahabilityForIP Push Notification Result.

If it is a TCAP OpenRequest message, then the PlanId selection key field is set to SRI4SM, MOFSM, MTFSM_<DeliveryOrder> [1] or UnknownACN. The configured DeliveryOrder is set in the MTFSMDeliveryOrder session state field unless MTFSMDeliveryOrder was already set.

If it is a Sh Push Notification Result, then the PlanId selection key field is set to Sh_PNR.

Otherwise, the feature does not set the PlanId field of the SentinelSelectionKey session state field.

In some cases the feature will also set the CallType in session state if it has not already been set by another feature.
