Abstract
An apparatus includes a home location register (203) that stores records for mobile units in a home system (201). A visited location register (213) stores records for mobile units presently registered in a visited system (211) in which the visited location register (213) is located. The visited system (211) identifies a last accessed technology by a mobile unit (221) in the visited system (211) and forwards the identification of the last accessed technology to the home location register (203). The identification of the last accessed technology may be forwarded to the home location register (203) in a registration notification. The home system (201) may forward a routing request including the identification of the last accessed technology to the visited system (213).
