FLEXIBLE NUMBERING IN MOBILE NETWORKS

摘要

In a mobile telecommunications network, a subscriber having a primary subscription on a home mobile network registers one or more flexible subscriber numbers on a secondary network that are associated with the primary subscription. A caller places a call to a subscriber through a serving network using the flexible subscriber number. The flexible subscriber number is translated into a primary MSISDN and the call is connected to the subscriber so that roaming charges to the subscriber are minimized.
