Abstract

Abstract The invention concerns a method of call processing in an intelligent telecommunications network of the kind comprising a matrix of physical network nodes known as service control points (2) and in which additional services are provided by the execution of service logical programmes (8, 9) residing on the physical network nodes. The invention is characterised in that call processing is divided into three separate segments, namely terminator segments (10, 11) containing the functions which deal with terminating or originating calls to or from a particular subscriber line or trunk circuit, associator segments (12) containing the functions concerning the establishment of a connection between two end parties represented by two terminator segments, and a feature segment for supporting an external interface to the service control points.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 119 words
A method of call processing in an intelligent telecommunications network of the kind comprising a matrix of physical network nodes known as service control points (2) and in which additional services are provided by the execution of service logical programmes (8,9) residing on the physical network nodes, and characterised in that call processing is divided into three separate segments, namely terminator segments (10, 11) containing the functions which deal with terminating or originating calls to or from a particular subscriber line or trunk circuit, associator segments (12) containing the functions concerning the establishment of a connection between two end parties represented by two terminator segments, and a feature segment for supporting an external interface to the service control points.
Claim 2
Dependent Claim 45 words
A method as claimed in Claim 1 and further characterised in that a feature segment is capable of supporting an interface which can be used for the purpose of creating, controlling and breaking connections across a digital switch forming part of the physical network node.
Claim 3
Dependent Claim 40 words
A method as claimed in Claim 2 and further characterised in that a feature segment includes a leg which represents a logical communications path towards some addressable entity in the network as viewed from the interior of the feature segment.
Claim 4
Independent Claim 93 words
A method as claimed in any one of the preceding claims and further characterised in that, when during the processing of a call, a trigger condition is detected within either the terminator or associator and the service switching point determines that external service logic must be involved in the further processing of the call, a new feature segment is created to support the external interface which is then interlinked with the existing terminator and associator segments so that via the feature segment, the service logical programme can influence the processing of the call.
Claim 5
Dependent Claim 39 words
A method as claimed in Claim 4 and further characterised in that connection segments of any of the three types are joined together by means of links each corresponding to a signalling and logical transport path between two segments.
Claim 6
Dependent Claim 39 words
A method as claimed in Claim 5 and further characterised in that the feature segment which has the highest priority for events from a particular source is directly linked with the segment which represents the source of those events.
