Abstract: Using intelligent network processing, call notification allows a subscriber to determine the name and telephone number of one or more numbers of recent parties to call the subscriber. An incoming call to the subscriber's number activates a terminating attempt type trigger in the central office serving the subscriber. The trigger causes communication between that office and a service control point (SCP). Under instructions from the SCP, the central office indicates a disposition event regarding the call, e.g., whether the line was busy or there was no answer. If the subscriber's line is busy or does not answer, the SCP records at least the telephone number of the caller and the time and date of the call. Later, the subscriber dials a feature code, and the SCP instructs the central office to route the call to an intelligent peripheral (IP).

Abstract: Telephone network surveillance is provided for targeting subscriber terminals that receive service through an office lacking a switch with surveillance capability. A foreign exchange line is relied upon to connect the target's line to an office having that capability. Advanced Intelligent Network (AIN) functionality controls routing and billing of incoming and outgoing calls, so that the telephone network operations appear completely normal during the surveillance. In the office normally serving the target's line, a terminating attempt trigger causes that office to obtain instructions from a service control point (SCP), to route the call to the foreign exchange line terminated in the office with the surveillance capability. The instructions also prevent billing of the redirection through the surveillance office to either the called party or the calling party.

Abstract: Following the Communications Assistance for Law Enforcement Act (CALEA), the FBI developed a standard set of communication services and interfaces for lawfully authorized electronic surveillance. For telephone communications, the current industry implementation of compliance with this standard involves deploying certain interface equipment in end office switches of the telephone network. However, the requisite surveillance functionality often resides in a certain limited number of offices. Where the target under surveillance receives service out of an office lacking the surveillance capability, the network routes the call through an office having the requisite capability. For this purpose, the invention relies on intelligent network processing, particularly variations on such processing normally used to implement local number portability.

Abstract: A method and system is disclosed for tracking call transaction data from incoming telephone calls, including attempted calls that have not been completed, made to individual predetermined subscribers during a defined time period. Information, including demographic breakdowns of calls, such as time of day, day of week, location of origin, etc. is reported automatically by the system. Through the use of the Advanced Intelligent Network (AIN) and Integrated Service Control Point (ISCP) platform, call transaction data for incoming calls are captured in response to terminating triggers at Service Switching Points (SSPs). The call originating phone number for each call may be used to access an existing telephone system billing database, called Customer Record Information System (CRIS), to obtain caller information, including zip code. The zip code, in turn, can be used to access a commercially available census data base to provide further demographic information.
