Abstract
The invention relates to a method of intercepting calls between two or more subscribers (A, B) of a communications networks (KOM) and to an interception manager and a service control platform for supporting the implementation of the method. For each of the calls, at least one of a plurality of service control points (SCP to SCP ) can be triggered by a service switching point (SSP to SSP ). The communications traffic between service switching points (SSP to SSP ) of the communications network and the service control points (SCP to SCP ) is routed through an interception manager (LIM) which is central to all service control points. The central interception manager (LIM) is triggered for a call when one (SCP ) of the service control points (SCP to SCP ) is triggered for this call by one (SSP ) of the service switching points (SSP to SSP ). When triggered for a call, the central interception manager (LIM) monitors the communications traffic between the respective service switching point (SSP ) and the respective service control point (SCP ) for the respective call and, based on information exchanged between the service switching point (SSP ) and the respective service control point (SCP ) and on predefined filter criteria, determines whether the call should be intercepted or not.
