Abstract
A network communications system comprises a number of user stations ( ), coupled via a data network ( ) to a number of service provider host systems ( ). The user stations ( ) are registered as client stations at the host system ( ) of a service provider, with the host system maintaining a database of registered client station identification data. The host system additionally maintains a directory of the client stations that are on-line at a given time, determined from periodic messages sent to the host by each client station. Callers ( ) wishing to contact a client station ( ) user first contact the service provider ( ) which, from the directory, determines whether the user is currently on-line. If so, a paging message is generated by the service provider from data supplied by the caller and sent via the network ( ) to the client station ( ), the address of which is held in the service provider database.
