Abstract
A system equipped with methods and an International Temporary Local Directory Number (TLDN) Translator. In accordance with one aspect of the invention, a device in a home domain uses the International TLDN Translator to receive operative routing information to a mobile phone roaming in a serve domain. The calling device contacts the local Public Switching Telephone Network (PSTN) with a request to contact the roaming mobile phone in the serve domain. Mobile Switching Center (MSC) sends a routing request to the International TLDN Translator, which forwards the request to the serve domain. The serve domain responds with a TLDN of the roaming mobile phone located in the serve domain. The International TLDN Translator modifies the TLDN to create a pseudo-TLDN that is operative from the home domain, such that a device in the home domain can contact the roaming mobile phone. The modification of the TLDN is performed by determining the dialing characteristics between the home domain and the serve domain.
