摘要

The system includes a device within each visited network for identifying the home network of each visiting subscriber. An element within each visited network determines whether or not the home network of each visiting subscriber has an automatic roaming agreement with the visited network. An element within each visited network classifies as an automatic visitor each visiting subscriber whose home network has an automatic roaming agreement with the visited network. Each visiting subscriber whose home network does not have an automatic roaming agreement with the visited network is classified as a manual visitor. Each visited network includes an element for maintaining a database of information on manual visitors. In the database is stored registration information regarding each manual visitor following an initial call attempt. Finally a device accesses from each of the visited network's mobile switching centres the database of registration information upon each manual visitors subsequent call attempts within the visited network.
