Method and process for validating roaming, international cellular users

摘要

A process for validating a roaming user who seeks access to a communications network operated by a first service provider is provided. The process includes determining that the user is associated with a second service provider and automatically sending a temporary deferring or denying message to the user when the user is associated with the second service provider; requesting registration data for the user to the second service provider; and validating or invalidating the user based on the registration data from the second service provider.
