Abstract: A Fixed-Mobile Convergence (FMC) network and method of handling calls in a FMC network. Registration is maintained for FMC User Equipment (UE) with at least two (a primary and a secondary) networks, e.g., a mobile network and a fixed network with a wireless connection capability. The primary network maintains subscribers numbers with each FMC UE being assigned one of the subscribers numbers. Calls to FMC UE are routed to the primary network and, if the UE is not present in the primary network, forwarded to the secondary network. A preferred FMC network may be implemented in existing fixed and mobile networks without requiring that one be integrated into the other.
