Method and system for providing an automatic customer callback service
First Claim
1. For use in Advanced Intelligent Network (AIN) having(a) a Central Office switch (COS) which is adapted to recognize an AIN T-busy trigger and is further provided in electrical communication with a Service Control Point (SCP) via Transaction Capability Application Part (TCAP) signalling protocol,(b) at least one calling party,(c) at least one called party, and(d) at least one end office provided in electrical communication with said at least one calling party,a method for providing an Automatic Customer Callback (ACC) Service, comprising:
- providing an adjunct processor in electrical communication with said COS;
collecting dialed digits and the calling party telephone number at said at least one end office through a Calling Party Identification (CPI) field in an ISDN User Part (ISUP) Initial Address Message (IAM);
monitoring said communications between said COS and said at least one calling party and said at least one called party to detect said T-busy trigger;
suspending normal call handling upon detection of said T-busy trigger and generating a corresponding first electrical signal for receipt by said SCP requesting further call processing instructions;
analyzing said collected digits to determine if said called party is an ACC service subscriber;
generating a second electrical signal for receipt by said COS indicating whether said ACC service may be activated;
providing to said adjunct processor said collected digits and said calling party telephone number if said ACC service is activated;
monitoring said subscriber telephone line to detect an idle condition;
originating a call from said adjunct processor to said subscriber upon detection of said idle condition; and
playing a message at said adjunct processor for receipt by said subscriber, whereupon said subscriber will be advised of the need to call back a calling party who has activated the ACC service.

Abstract
Automatic Customer Callback (ACC) functionality is implemented directly into service logic of an Advanced Intelligent Network (AIN). The Advanced Intelligent Network includes a Central Office Switch (COS) which is provided in electrical communication with Service Control Point (SCP), at least one calling party, and at least one called party. The AIN components preferably communicate with one another through Transaction Capability Application Part (TCAP) signaling protocol and are directed for use in an AIN 0.2 network. An adjunct processor such as an Intelligent Peripheral (IP) is also provided in electrical communication with the COS. In operation, digits dialed by the calling party (those corresponding to the telephone number of the called party) are collected as well as the calling party telephone number. If the called party line is busy, then the calling party activates the Automatic Customer Callback (ACC) service, the subscriber'"'"'s telephone line will be monitored to detect an idle condition. Once this condition is detected, a call may be originated from the adjunct processor to the subscriber whereupon a message may be played for receipt by the subscriber advising the same of the need to call back the calling party who has activated the ACC service. In an alternative embodiment, a three-way call is automatically originated from the adjunct processor to the subscriber and the calling party where, following completion of the call, the adjunct processor will disconnect itself.

4. For use in an Advanced Intelligent Network (AIN) including
(a) a Central Office Switch (COS) which is adapted to recognize an AIN T-busy trigger and is further provided in electrical communication with a Service Control Point (SCP) via Transaction Capability Application Part (TCAP) signalling protocol, (b) at least one calling party, (c) at least one called party, and (d) at least one end office provided in electrical communication with said at least one calling party, and a method for providing an Automatic Customer Callback (ACC) service, comprising: -
providing an adjunct processor in electrical communication with said COS; collecting dialed digits and the calling party telephone number at said at least one end office through a Calling Party Identification (CPI) field in an ISDN User Part (ISUP) Initial Address Message (IAM); monitoring said communications between said COS and said at least one calling party and said at least one called party to detect said T-busy trigger; suspending normal call handling upon detection of said T-busy trigger and generating a corresponding first electrical signal for receipt by said SCP requesting further call processing instructions; analyzing said collected digits to determine if said called party is an ACC service subscriber; generating a second electrical signal for receipt by said COS indicating whether said ACC service may be activated; providing to said adjunct processor said collected digits and said calling party telephone number if said ACC service is activated; monitoring said called party line to detect an idle condition; and automatically originating a 3-way call from said adjunct processor to said subscriber and said calling party upon detection of said idle condition and disconnecting said adjunct processor from said call upon completion, whereby said subscriber will automatically return the call of said calling party who has activated said ACC service. - View Dependent Claims (5, 6)

8. For use in an Advanced Intelligent Network (AIN), a system for providing an Automatic Customer Callback (ACC) service for a subscribing called party to call back a calling party, comprising:
-
at least one end office provided in electrical communication with said calling party for collecting dialed digits and the calling party telephone number through a Calling Party Identification (CPI) field in an ISDN User Part (ISUP) Initial Address Message (IAM) so as to originate a telephone call; a Service Control Point (SCP) operative to analyze said collected digits and detect said ACC service subscribers; a Central Office Switch (COS) adapted to recognize an AIN T-busy trigger and thereupon suspend normal call handling and request further call processing instructions from said SCP and said calling party, said COS provided in electrical communication with said calling party, said called party and said SCP via Transaction Capability Application Part (TCAP) signalling protocol; and an adjunct processor for receiving and storing said collected digits and said calling party telephone number upon activation of said ACC service and coordinating the call back of said calling party by said subscriber, said adjunct processor provided in electrical communication with said COS. - View Dependent Claims (9, 10, 11, 12, 13)
