National mobile networks are provided with a proxy location register for storing user identities in association with respective network identities. Users have an associated &ldquo;mobile home&rdquo; 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.

A support structure for an operational telecommunications network deploys a set of individual technologies and provides a set of services to customers. The support structure is divided into a set of domains each of which provides a particular management function for the network. These domains include a domain for managing customer handling functions, a domain for managing the network, a domain for managing the individual technologies deployed in the network, a domain for managing instances of the individual services provided by the network, a domain for managing billing operations, a domain for managing the services provided by the network when grouped together to form a portfolio, and a domain for managing jobs performed by the human workforce for the network. Each domain has its own set of databases and systems for performing the required management operations and also interfaces to some of the other domains. Each domain is implemented by one or more tightly integrated computers. The interfaces between the domains are primarily message passing interfaces.
