A signaling gateway for passing messages from a first network to an application server process provided on a second network, the messages comprising a transaction identifier, the signaling gateway being operable to receive a message and read the transaction identifier, identify the application server process from a part of the transaction identifier and forward the message to the application server process.

Signaling gateway

According to one aspect of the present invention, there is provided a method, in a communication system having a plurality of communication devices each having a first and second identifier associated therewith at the time of a connection attempt to the network, of identifying when one of the identifiers has been cloned, the connection status of the first identifier being obtainable from a network element, comprising receiving the first and second identifiers of a communication device, determining whether one of the identifiers has been cloned, the determination being made in part through information obtained from a connection history database, and in part through information obtained from the network element.

Detection of cloned identifiers in communication systems

A method of operating a gateway is disclosed to manage communications between a switched circuit network and an internet protocol network using a gateway. The method includes receiving at the gateway, a service call requesting the service for routing to an application server on the internet protocol network. If the application server is available the service call is routed to the first application server and the gateway generates an entry in its database. The entry includes the service identifier and the first application server identifier. If the application server is not available to accept the service call and the service call is routed to the application server when it is not available, the method includes sending a control message to the calling party on the switched circuit network.
