Abstract
Local signal transfer points (LSTPs) are optimally selected for removal from a Signaling System Number 7 (SS7) network. At least one network element is connected to each LSTP and each LSTP is connected to a parent node. Each LSTP is determined as a flexible LSTP or a fixed LSTP. A potential network configuration is formed with at least one flexible LSTP excluded. Each network element is reconnected to one LSTP in the potential network configuration and each LSTP in the potential network configuration is reconnected to one parent node. A total cost based on the potential network configuration is determined. The potential network configuration becomes the new best network configuration if the total cost is less than any previous total cost. The process is repeated for each potential network configuration resulting from removing a different combination of flexible LSTPs.
