摘要

A system and method of providing an intelligent automatic roaming analysis (ARA) that enables a roaming mobile subscriber (130) to use abbreviated dialing regardless of the location of the subscriber in a radio telecommunications network (100). The radio telecommunications network includes a home network (106) which comprises a Home Location Register (HLR) (112) and a Service Control Point (SCP) (114). The visited exchanges (122; 124; 126) of the network are categorized by a type indicator (314) if locate d outside the home service area (102). Subscription data (300A) and operator service data (300B) are provided as a database in the SCP (114), wherein applicable telephone codes (306; 308; 310; 312) are available for the home network (106) and the visited exchanges (122; 124; 126). Based on the type o f 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.
