Abstract

Abstract An intelligent call processing system is arranged so that each originating switch is provided with a local database called a "global title translation (GTT)" database, which receives a query fully identifying the calling station, typically in terms of its 10 digit number (i.e., three digit [NPA] area code, three digit [NXX] exchange, and four digit line identification). The GTT database responds to the query by identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call. If the GTT database does not contain an entry, or an error condition exists, a further query is launched to a centralized database, called a "universal global translation (UGT)" database. The UGT database then retrieves information identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call, and provides this information to the originating switch. The same information may also be provided to and stored in the GTT database, so that the GTT database is "self provisioning".

Claims Analysis

Total Claims: 8

Claim 1

Independent Claim 160 words

A system for intelligent processing of telephone calls in accordance with prestored instructions associated with the station from which said telephone calls are originated, said system including a local database and a centralized database, each containing information indicating the locations of a plurality of telecommunications network databases that contain call processing records for completing telephone calls; means responsive to receipt of a telephone call and information identifying a particular station from which said telephone call was originated, for routing a query to said local database to retrieve the location of a particular one of said plurality of telecommunications network databases that contains a call processing record for completing said telephone call; and means for routing a query to said centralized database to retrieve said location of a particular one of said telecommunications network databases that contains said call processing record for completing said telephone call only if said local database does not contain an entry associated with said particular station.

Claim 2

Dependent Claim 24 words

The invention defined in claim 1 wherein said system further includes means for updating said local database with information obtained from said centralized database.

Claim 3

Dependent Claim 21 words

The invention defined in claim 1 wherein said system further includes means for periodically deleting information stored in said local database.

Claim 4

Dependent Claim 23 words

The invention defined in claim 1 wherein said information identifying a particular station from which said telephone call was originated includes ANI information.

Claim 5

Independent Claim 159 words

A method for intelligent processing of telephone calls in accordance with prestored instructions associated with the station from which said telephone calls are originated, said method including the steps of storing information indicating the locations of a plurality of telecommunications network databases that contain call processing records for completing telephone calls in a local database and a centralized database; responsive to receipt of a telephone call and information identifying a particular station from which said telephone call was originated, routing a query to said local database to retrieve the location of a particular one of a plurality of telecommunications network databases that contains a call processing record for completing said telephone call; and routing a query to said centralized database to retrieve said location of a particular one of said telecommunications network databases that contains said call processing record for completing said telephone call only if said local database does not contain an entry associated with said particular station.

Claim 6

Dependent Claim 25 words

The method defined in claim 5 wherein said method further includes the step of updating said local database with information obtained from said centralized database.

Claim 7

Dependent Claim 22 words

The method defined in claim 5 wherein said method further includes the step of periodically deleting information stored in said local database.

Claim 8

Dependent Claim 23 words

The method defined in claim 5 wherein said information identifying a particular station from which said telephone call was originated includes ANI information.
