Abstract:
1. A signaling proxy system for a network node, the network node including a plurality of processing blades of a blade cluster, comprising: at least two signaling proxies for routing signaling traffic between a remote network node and the plurality of processing blades, each signaling proxy simultaneously having the same signaling point code and operable in one of an active state and a passive state towards the remote network node; wherein one of the at least two signaling proxies is operating in an active state, and wherein each of the remaining signaling proxies is configured to remain during operation in a passive state with the signaling point code passive towards the remote network node when receiving an indication confirming that the one of the at least two signaling proxies is operating in the active state; and wherein each of the remaining signaling proxies is configured to activate itself during operation towards the remote network node by activating the signaling point code towards the remote network node when in a passive state and when not receiving the indication; and wherein the indication is transmitted from the one of the at least two signaling proxies operating in the active state to at least one of said processing blades and then from the at least one of said processing blades to the remaining signaling proxies.
