2.1.5.8 CGPNNP Service Action Handler

The CGPNNP Service Action Handler performs an Number Portability lookup on the CgPN digits from the ISUP IAM message.

The CGPNNP Service Action Handler is supported for the TIFCGPN, TIFCGPN2, and TIFCGPN3 services, which are invoked only if the INVKSERV parameter value is not NONE for the corresponding TIF, TIF2, or TIF3 service.

The CGPNNP Service Action can be provisioned with any of the other Service Actions supported by the TIFCGPN, TIFCGPN2, and TIFCGPN3 services except for FPFXRLS.

Configuration Options Used

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

The value of the TIFOPTS DFLTRN option, if set, is used to populate the RN on a successful DN match and the effective entity type is SP.

The TIFOPTS SPFILL option indicates whether SP should be populated when the DFLTRN value is used for the RN value.

Action Performed

Number Portability lookup is performed on the conditioned digit string in international format. The result is determined based on the TIFOPTS NPTYPECGPN option value.

On a lookup where an RN or SP entity was found
  • The SRFIMSI digits assigned to the entity are used to populate the SRFIMSI Formatting Action value.
  • If the IGM feature is turned on, Entity Type is RN, and PT=0, then the Entity Type is treated as SP (in-network subscriber).

If a match is found and the Entity Type is RN, then RN digits are inserted into the outgoing field.

If a match is found and the effective Entity Type is SP, then SP digits are inserted into the outgoing field or the DFLTRN option digit string can be used to populate the RN Formatting Action value instead of actual SP digits.

If a match is found and the Entity Type is SP, then SPFILL=ON causes the SP digits to populate the SP Formatting Action value when the DFLTRN value is used to populate the RN Formatting Action value.

On a lookup where an entry was found, but entity data was not found (NPTYPECGPN=ALL), the CgPN is unchanged, if the Formatting Actions do not modify the digits in some other manner.

Formatting Action processing is skipped on an unsuccessful lookup. Depending on the Formatting Action configuration for the selected rule, the updated RN, SP or SRFIMSI can be used during CgPN formatting by NPP.

Terminating Action?

This is not a terminating action.
