N2SCP Applications

Overview

N2SCP provides the LhoScpApp application for use in N2SVCD - a General Purpose Logic SCP (used by N2ACD, etc.).

Traffic Type Determination

Calls handled by N2SCP applications may be for Originating, Forwarding, or Terminating call legs. Some factors of processing (e.g. Special Number rules) may take the traffic type into account for rule selection.

All N2SCP applications apply the following rules, in order, to determine the traffic type of a received InitialDP:

1. If the InitialDP → EventTypeBCSM field value is 12 (termAttemptAuthorized), set the traffic type to Terminating.

2. If:

   1. The SSP model inap value is camel1, camel2, camel3, or camel4.
   2. The InitialDP → EventTypeBCSM field value is 2 (CollectedInfo) or 3 (AnalyzedInformation).
   3. The InitialDP → locationInformation field is not present.

   …set the traffic type to Forwarding.

3. If:

   1. The SSP model inap value is cs1.
   2. The InitialDP → EventTypeBCSM field value is 2 (CollectedInfo) or 3 (AnalyzedInformation).
   3. The InitialDP → redirectingPartyID field is present.

   …set the traffic type to Forwarding.

4. If the InitialDP → EventTypeBCSM field value is 2 (CollectedInfo) or 3 (AnalyzedInformation), set the traffic type to Originating.

For N2SCP applications, this call type may be used by Special Number rules as required.
