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.

Abstract
A signalling proxy system for a switching center server is provided, as well as a method of operating a signalling proxy system for a switching center server. The signalling proxy system comprises two signalling proxies for routing signalling traffic between a network node and a plurality of switching center server units. Each signalling proxy is addressable by an address code and is operable in one of an active state and a passive state towards the network node.

14. A method of operating a signaling proxy system for a network node, the network node including a plurality of processing blades of a blade cluster, the method comprising:
-
operating a first signaling proxy in an active state with a signaling point code of the first signaling proxy active towards a remote network node for routing signaling traffic between the remote network node and the plurality of processing blades; operating a second signaling proxy in a passive state with a signaling point code of the second signaling proxy passive towards the remote network node, the signaling point code of the second signaling proxy simultaneously being the same as the signaling point code of the first signaling proxy; providing to the second signaling proxy an indication that the first signaling proxy is operating in an active state, 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; and activating the second passive signaling proxy towards the remote network node when it is not receiving the indication. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A non-transitory electronically readable data carrier with stored electronically readable control information configured such that when using the data carrier in a computer system, the control information causes the computer to operate a signaling proxy system for a network node, the network node including a plurality of processing units comprising processing blades of a blade cluster, by performing the steps of:
-
operating a first signaling proxy in an active state with a signaling point code of the first signaling proxy active towards a remote network node for routing signaling traffic between the remote network node and the plurality of processing units; operating a second signaling proxy in a passive state with a signaling point code of the second signaling proxy passive towards the remote network node, the signaling point code of the second signaling proxy simultaneously being the same as the signaling point code of the first signaling proxy; providing to the second signaling proxy an indication that the first signaling proxy is operating in an active state, 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; and activating the second passive signaling proxy towards the remote network node when it is not receiving the indication.
