Intercepting call communications within an intelligent network
First Claim
1. A method for providing telecommunications service to a particular subscriber within a telecommunications network, said particular subscriber associated with a serving service switching point (SSP), and the telecommunications network having a first service control point (SCP) designated to provide general service only to a selected group of a plurality of groups of subscribers, wherein the selected group includes the particular subscriber and the telecommunications network further including a second service control point (SCP) designated to provide special services to the plurality of groups of subscribers, said method comprising the steps of:
- receiving at said SSP an indication to establish a call connection with said particular subscriber;
determining whether said particular subscriber is associated with a first trigger flag;
in response to a determination that said particular subscriber is associated with said first service trigger flag;
querying said first SCP associated with said selected group of subscribers for routing instructions; and
providing telecommunications general service in accordance with said queried for routing instructions from said first SCP;
determining whether said particular subscriber is associated with a second trigger flag; and
in response to a determination that said particular subscriber is associated with said second service trigger flag;
querying said second SCP associated with plurality of groups of subscribers for routing instructions; and
providing telecommunications special service in accordance with said queried for routing instructions from said second SCP.

Abstract
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.

9. A method for effectuating a call connection with a particular subscriber within a telecommunications network, and the telecommunications network having a first service control point (SCP) designated to provide general service only to a selected group of a plurality of groups of subscribers, wherein the selected group includes the particular subscriber and the telecommunications network further including a second service control point (SCP) designated to provide special services to the plurality of groups of subscribers, said method comprising the steps of:
-
receiving an indication to establish a call connection with said particular subscriber; determining whether said particular subscriber is associated with a subscriber service trigger flag; in response to a determination that said particular subscriber is associated with a subscriber service trigger flag comprising a call interception trigger flag, communicating with the first service control point (SCP) for routing instructions; and in response to a determination that said particular subscriber is associated with a subscriber service trigger flag comprising an intelligent network service trigger flag, communicating with the second service control point (SCP) for routing instructions. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for effectuating a call connection with a particular subscriber terminal within an Intelligent Network (IN) based telecommunications network, comprising:
-
a service switching point (SSP) connected to said subscriber terminal, said SSP receiving an indication to establish a call connection with said subscriber terminal; an application module associated with said SSP for performing a B-number analysis for a directory number associated with said indication, said application module further determining whether said directory number is associated with a trigger flag; an intercept device associated with said telecommunications network for intercepting voice and data communications; a second service control point (SCP) for providing routing instructions to effectuate said call connection in response to a determination that said directory number is associated with a trigger flag for IN service; and a first service control point (SCP) for providing routing instructions to effectuate a communication link with said intercept device in response to a determination that said directory number is associated with a trigger flag for call interception. - View Dependent Claims (16, 17, 18, 19)
