| 摘要 |
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 (SCP1 to SCP3) can be triggered by a service switching point (SSP1 to SSP3). The communications traffic between service switching points (SSP1 to SSP3) of the communications network and the service control points (SCP1 to SCP3) 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 (SCP1) of the service control points (SCP1 to SCP3) is triggered for this call by one (SSP1) of the service switching points (SSP1 to SSP3). When triggered for a call, the central interception manager (LIM) monitors the communications traffic between the respective service switching point (SSP1) and the respective service control point (SCP1) for the respective call and, based on information exchanged between the service switching point (SSP1) and the respective service control point (SCP1) and on predefined filter criteria, determines whether the call should be intercepted or not.
