Network Node and Method of Routing Messages in an IP-Based Signaling Network

A method of routing messages in an IP based signaling network using a network node comprising at least two interfaces each towards a remote network node of the IP based network, each remote network node implementing a remote signaling process, the method comprising:

• routing an incoming message received at a first of the at least two interfaces to a second interface of the at least two interfaces, the routing comprising translating the incoming message into a corresponding outgoing message in dependence on a type of the remote signaling process of the remote network node at the first interface and a type of the remote signaling process of the remote network node at the second interface.

A relay network using an IP based user adaptation protocol for relaying signaling messages comprising plural network nodes as relay nodes, each network node being configured to route messages in an IP based signaling network and comprising:

• at least two interfaces each towards a remote network node of the IP based network, each remote network node implementing a remote signaling process;
• and
• a processing unit configured to route an incoming message received at a first of the at least two interfaces to a second interface of the at least two interfaces, the routing comprising a translating of the incoming message into a corresponding outgoing message in dependence on a type of the remote signaling process of the remote network node at the first interface and a type of the remote signaling process of the remote network node at the second interface.

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 routes messages in an IP based signaling network using a network node that comprises at least two interfaces each towards a remote network node of the IP based network, each remote network node implementing a remote signaling process, the control information routing messages by routing an incoming message received at a first of the at least two interfaces to a second interface of the at least two interfaces, the routing comprising translating the incoming message into a corresponding outgoing message in dependence on a type of the remote signaling process of the remote network node at the first interface and a type of the remote signaling process of the remote network node at the second interface.
