ABSTRACT:
In a cellular telecommunication network utilizing home location registers for completion of calls to and from a mobile station, a system and method is disclosed for loading and accessing database information relating to the mobile station, and completing calls to the mobile station while roaming in a visited foreign network without incurring long distance charges. The radio telecommunication system includes a mobile station having a mobile subscriber number (MSNB) and a first subscriber number (SNB), a home network having a mobile switching center (MSC) and a first home location register (HLR) which maintains database information relating to the mobile station, and a visited foreign network having a visited mobile switching center (V-MSC) and a second HLR. When the mobile station roams into the visited foreign network, a second SNB is assigned to the MSNB, and subscriber information is stored in the second HLR. When a call is received for the mobile station on the second SNB, the V-MSC accesses the second HLR for subscriber information and completes the call locally to the mobile station.
