A method of operating a signaling gateway for routing signaling messages between a SS7 network and an IP-based network is provided. The signaling gateway has a signaling point code allocated as a network address. Further, a signaling gateway for routing signaling messages between a SS7 network and an IP-based network is provided. The signaling gateway comprises an interface towards the SS7 network and an interface towards the IP-based network. The signaling gateway comprises a processing unit which may implement a SS7 protocol stack and an IP protocol stack. The processing unit may be configured to translate a message delivered to an upper protocol layer of the SS7 protocol stack to a corresponding message conforming to a user adaptation protocol of the IP protocol stack.

Signaling gateway for routing signaling messages

A method of operating a signalling gateway in a decoupled mode of operation for routing signalling messages between an SS7 and an IP-based network is provided. Further, the invention relates to a method of processing a connection oriented signalling message at an application server process, wherein the message is exchanged via a signalling gateway between an SS7 network node and the application server process. The application server process serves at least one application server in an IP-based network. The invention further provides a signalling gateway for routing signalling messages between an SS7 network and an IP-based network and an application server comprising an application server process for processing signalling messages, in particular connection oriented messages.

Method of operating a signalling gateway and an application server, and signalling gateway and application server

A telecommunications system. The system includes a communications network. The system includes N nodes, where N is an integer greater than or equal to 2, which run a same or different applications and process a same or different ranges of application level traffic, and which communicate with each other through the network using signaling by SIGTRAN protocols. Each of the N nodes has a full receive state where a node receives any type of traffic from the other nodes and an isolated receive state where the node only receives allocated traffic from the other nodes. The node sends traffic to the other nodes whether the node is in the full receive state or the isolated receive state. A method for communicating.
