6.2.1 Conversion of National/Local Numbers to International Numbers
Table 6-2 National/Local Numbers to International Numbers Conversion Logic
Service Numbering Plan | Service Nature of Address | Action |
---|---|---|
E.164 |
National (Significant) number |
Prepend GTAI digits with the default E.164 Country Code (CC). |
E.164 |
Subscriber number |
Prepend GTAI digits with the default E.164 country code (CC) and network code (NC). |
E.212 |
National (Significant) number |
Prepend GTAI digits with the default mobile country code (MCC). |
E.212 |
Subscriber number |
Prepend GTAI digits with the default Mobile Country Code (MCC) and Mobile Network Code (MNC). |
E.214 |
National (Significant) number |
Prepend GTAI digits with the default E.164 Country Code (CC). |
E.214 |
Subscriber number |
Prepend GTAI digits with the default E.164 Country Code (CC) and Network Code (NC). |
Other |
N/A |
Assume the default to be E.164 International number |
Notes:
-
If any of the default CC, NC, MCC, or MNC are required for conversion and are not provisioned in the database, G-Flex Relay issues a measurement and falls through to GTT.
-
If the converted number is fewer than five digits, G-Flex Relay falls through and performs GTT on the message. G-Flex Relay issues a measurement when a converted number is fewer than five digits.
-
If the converted number is more than 15 digits, then G-Flex Relay issues a measurement when the number exceeds 15 digits and falls through to GTT.
-
G-Flex Relay uses the conditioned number for database lookup purposes only and does not modify the CdPA GTAI in the message unless rcgta=yes or ccgt=yes.
-
For the G-Flex selector-specified service numbering plan (IMSI, DN, or MGT), the numbering plan in the incoming message is replaced with the G-Flex Selector service numbering plan (E.164, E.212, or E.214, respectively). This is for GDB lookup purposes only.
