Abstract
A system and method of providing an intelligent automatic roaming analysis (ARA) that enables a roaming mobile subscriber to use abbreviated dialing regardless of the location of the subscriber in a radio telecommunications network. The radio telecommunications network includes a home network which comprises a Home Location Register (HLR) and a Service Control Point (SCP). The visited exchanges of the network are categorized by a type indicator if located outside the home service area. Subscription data and operator service data are provided as a database in the SCP, wherein applicable telephone codes are available for the home network and the visited exchanges. Based on the type of the visited exchange, an abbreviated number is rebuilt into an appropriate called party number (B-number) by utilizing one or more services provided in the SCP.
