Abstract
Planning alternative SS7 networks is a complex task requiring assistance from an intelligent planning tool. The tool includes at least one planning database containing information on network traffic, component locations, and component connectivity. A load module determines peak load for each STP in the core network. A forecast module determines equipment capacity exhaustion for each STP, network database, and core link during each study period and determines network costs based on peak loads and an alternative network design provided by a user. A graphical user interface guides the user through a sequence of design steps, each step having to be correctly completed before the next step in the sequence is started. The sequence of steps may include permitting changes to the core network, permitting changes to the number of POPs and DBs, rehoming elements left disconnected from STPs, assigning SSPs to POPs, assigning SSPs to DBs, and permitting voluntary rehomes.
