Abstract: A method for integrating fixed terminals in a mobile telecommunications network capable of handling calls to and from registered subscribers, comprising the steps of: connecting the fixed terminals through fixed lines to an interface unit for the mobile network; providing a register for storing, for each subscriber, subscriber information by which the subscriber is addressable; storing, as part of the subscriber information, access information specifying one or more predefined access types, that are available for that subscriber, and specifying whether or not the subscriber has multiple access to the network; and controlling the call handling on the basis of the stored access information.
