2.1.5.7 NPNRLS Service Action Handler

The NPNRLS Service Action Handler performs a lookup on the conditioned CdPN digit string and indicates Release behavior on an unsuccessful lookup.

Configuration Options Used

The TIFOPTS NPTYPERLS configuration option indicates the conditions used for a successful match.

The destination-based NPRST configuration option and the TIFOPTS NPFLAG configuration option indicates when and how the NM bits should be processed.

The TIFOPTS RLCOPC option indicates whether the destination-based RCAUSE configuration option value or the TIFOPTS RCAUSENP configuration option value is used as the Release Cause to be included in the Release message.

The RCAUSEPFX configuration option indicates the Reason Cause Value to be included in a Release message.

Action Performed

This Service Action Handler uses the incoming NM bit decode result to determine if a lookup has already been performed.

If the TIFOPTS NPFLAG configuration option is set to NM and the NM bits indicate that a lookup has already been performed, then the Service Action Handler returns immediately.

If the NM bits indicate that a lookup has not already been performed, the Number Portability lookup is performed and does not return a match.

In this no-match case, a Release message will be sent with a Release Cause specified in the RCAUSE option or the RCAUSEPFX option. The Redirection Number is not included in the Release message.

This Service Action Handler provides no inputs to Formatting Actions.

The post-NPP processing sends a Release message with a Release Cause that is configured in the RCAUSE option or the RCAUSEPFX option. The Redirection Number is not included in the Release message.

Terminating Action?

In the no-match case, this is a terminating action.
