Abstract: A signaling aggregator and method for signal aggregation alleviate port exhaustion at network nodes such as mobile switching centers (MSCs), home location registers (HLRs), and other signaling network nodes. The signaling aggregator is inserted between any signaling node requiring a plurality of signaling links, to relieve signaling port exhaustion. The signaling aggregator is connected to the signaling node by a high-speed linkset and transparently transfers signaling messages between the signaling node and other signaling nodes connected to the signaling aggregator. The signaling aggregator masquerades as the signaling node to the other signaling nodes, utilizing the point code of the signaling node in the originating point code (OPC) field of signaling messages sent to the other signaling nodes. The signal aggregator may also provide protocol conversion between two or more signaling protocols. Mated signaling aggregators are used to provide redundancy.
