Telecommunications system SS7 signaling interface with signal transfer capability
First Claim
1. A method for use in an SS7 signaling interface within a telecommunications network, said SS7 signaling interface having a host element associated therewith, said method comprising the steps ofreceiving, over an incoming link from a particular originating element within said network, incoming SS7 messages addressed to different elements within said network,applying, to said associated host element, the SS7 application data contained in each received incoming message for which said associated host element is the addressed element, said applying using a protocol which is exclusive of the SS7 message transfer part, andapplying, to selected SS7 signaling links connected to said interface, outgoing SS7 messages which contain SS7 application data contained in ones of the received incoming SS7 messages for which the addressed element is other than said associated host element.

Abstract
Network elements in a telecommunications network, such as toll switches, databases and the like, are provided with redundant SS7 signaling interfaces based on different software designs. At least one of the interfaces, referred to as a network endpoint signaling transfer point, or NESTP, is loosely coupled to its host and has signaling transfer point (STP) capabilities. In a routing table within the NESTP, a plurality of prioritized route lists are provided for at least some destinations, the list that is used to route a particular message to such a destination being a function of the route by which that message arrived at the NESTP.

1. A method for use in an SS7 signaling interface within a telecommunications network, said SS7 signaling interface having a host element associated therewith, said method comprising the steps of
receiving, over an incoming link from a particular originating element within said network, incoming SS7 messages addressed to different elements within said network, applying, to said associated host element, the SS7 application data contained in each received incoming message for which said associated host element is the addressed element, said applying using a protocol which is exclusive of the SS7 message transfer part, and applying, to selected SS7 signaling links connected to said interface, outgoing SS7 messages which contain SS7 application data contained in ones of the received incoming SS7 messages for which the addressed element is other than said associated host element.

5. An SS7 signaling interface for use in a telecommunications network, said SS7 signaling interface having a host element associated therewith, said SS7 signaling interface comprising
lower level SS7 function means for receiving, over an incoming link from a particular originating element within said network, incoming SS7 messages addressed to different elements within said network, and for extracting the SS7 application data contained in each received incoming message, message transfer means for obtaining, from said lower level SS7 function means, the extracted SS7 application data and an indication of the element to which said each received message was addressed; - for applying, to selected SS7 signaling links connected to said SS7 signaling interface, outgoing SS7 messages which contain SS7 application data contained in ones of the received incoming SS7 messages for which the addressed element is other than said associated host element; and
endpoint function means for receiving, from said message transfer means, the SS7 application data contained in each received incoming message for which said associated host element is the addressed element and for applying that data to said associated host element using a protocol which is exclusive of the SS7 message transfer part. - View Dependent Claims (6, 7)
