Abstract
National mobile networks are provided with a proxy location register for storing user identities in association with respective network identities. Users have an associated “mobile home” for storing call handling instructions and messages recorded by a Voicemail system. When a user roams from a current host network to a visited network, he may request that his mobile home be moved from its current location, most likely that current host network, to the visited network, and retrieval of any messages that have been left for that user can now be done without involving real-time use of international links between networks. Furthermore, when the mobile home has moved, its new location, with or without call handling instructions, can be manually or automatically notified to all other networks, or a subset, for location register updating. The use of this location information can avoid tromboning over expensive international links, and the call handling instructions enables remote networks to decide if a connection is to be attempted to a destination network.
