6.1.1 Number Conditioning

Incoming SCCP CdPAs (Called Party Numbers) destined for G-Flex processing are conditioned as follows to fit the GDM (G-Flex Database) lookup requirements where possible:

  • If the G-Flex GTT selectors available in the incoming message match an entry in the Selector table, then the service Numbering Plan from the Selector table entry uses the CdPA Numbering Plan. Further conditioning is applied based on the CdPA Numbering Plan.

  • If the G-Flex GTT selectors available in the incoming message match an entry in the Selector table, then the service Nature of Address from the Selector table entry uses the CdPA Nature of Address. Further conditioning is applied based on the CdPA Nature of Address.

  • If the Nature of Address is National (Significant), the default CC (country code for E.164 or E.214) or default MCC (mobile country code for E.212) is prepended to the number for GDM look up. The default country code to be used by vSTP, must be previously provisioned. If not, a measurement is issued, and the message falls through to GTT.

  • If the Nature of Address is Subscriber, the default CC + default NC (network code for E.164 or E.214) or default MCC + default MNC (for E.212) are prepended to the number. The default codes to be used by vSTP must be previously provisioned. If not, a measurement is issued, and the message falls through to GTT.

  • If the Numbering Plan is E.214, the CC + NC part of the number is replaced with its corresponding MCC + MNC from the provisioned conversion data. If no matching CC + NC has been provisioned, a measurement is issued, and the message falls through to GTT.

Numbers with fewer than 5 digits after the conditioning are not processed by G-Flex. A measurement is issued, and the message falls through to GTT.

Numbers with more than 15 digits after the conditioning are not processed by G-Flex. A measurement is issued, and the message falls through to GTT.
