摘要： A first service control point (SCP) for providing law enforcement related call interception capability and a second SCP for providing conventional Intelligent Network (IN) subscriber service features are both provided within an IN based telecommunications network. Two types of trigger flags are then associated with a service switching point (SSP) serving a particular subscriber. Where a first trigger flag associated with call interception is set, a query signal requesting interception routing instructions is transmitted from the serving SSP to the first SCP using a pre-stored network address. Where a second trigger flag associated with an IN service is set, a query signal requesting IN service routing instructions is transmitted from the serving SSP to the second SCP using a directory number associated with the associated subscriber.
