Example of Outside World Area 1
This example shows the actual practice which is not clearly described in the standards.
Translation rule:
- match numbers starting 28401 (Bulgaria mobile country code + MobilTel MNC)
- identify this as belonging to MobilTel-Bulgaria network
- remove first five digits (length of MCC+MNC)
- prepend 35988 (Bulgaria E.164 country code + a Bulgarian local prefix reaching MobilTel's network)
- mark the number as having E.214 numbering plan.
- route message on Global Title across SCCP network
so we get 284011234567890 becomes 359881234567890 numbering plan E.214.
Translation rule:
- match numbers starting 310150 (America first MCC + Cingular MNC)
- remove first six digits (length of MCC+MNC)
- prepend 14054 (North America E.164 country code + Network Code for Cingular)
- mark the number as having E.214 numbering plan.
- route message on Global Title across SCCP network
so we get 310150123456789 becomes 14054123456789 numbering plan E.214.
The result is an E.214 compliant Global Title, (Numbering Plan Indicator is set to 7 in the SCCP message). This number can now be sent to Global Title Analysis. by onmobile
