Title: System for connecting a telephone switch to a fixed telephone network via a plurality of fixed radiotelephone terminals

Abstract: A system includes: a plurality of fixed radiotelephone terminals connected to a telephone switch serving user terminals; call forwarding circuitry for forwarding a call addressed to one of the user terminals to a mobile service switching center managing the radiotelephone terminals, and providing access to the called user terminal, the forwarded call containing the identity of the called user terminal and containing the identity of the fixed radiotelephone terminal that is the first available in a list of radiotelephone terminals associated with the identity of the called user terminal; and, circuitry situated in the switching center to forward the call to a second fixed radiotelephone terminal designated by its international mobile subscriber identity number if the first terminal is busy. If the second terminal is busy, the switching center forwards the call to a third fixed radiotelephone terminal designated by its international mobile subscriber identity number. The system continues until a non-busy terminal can be used, while making use of a home location register only once. The switching center supplies the identity of the called user terminal to the radiotelephone terminal being used. The system is suitable for extending the public telephone network to isolated communities.
