SYSTEM AND METHOD FOR DETERMINING CHARACTERISTICS FOR INTERNATIONAL CALLS
First Claim
1. An automated method of providing information for an international telephone number, the method comprising:
- receiving an international telephone number from a user via a secure network connection;
in response to receiving the international telephone number, consulting a table of prefixes in a centralized database of characteristics to identify a longest matching prefix for the international telephone number;
in response to identifying the longest matching prefix, automatically consulting a location table in the centralized database to retrieve location information associated with the longest matching prefix; and
in response to retrieving the location information associated with the longest matching prefix, automatically transmitting the location information to the user.

Abstract
A system for providing termination information for an international telephone number includes a centralized database of terminating characteristics. The system may also include request processing logic that receives an international telephone number from a user. In response to receiving the telephone number, the request processing logic may automatically query the centralized database to obtain information that indicates whether the telephone number uses wireless termination. In response to obtaining the information from the centralized database, the request processing logic may automatically transmit to the user a response that indicates whether the telephone number uses wireless termination. The system may also include a database engine that uses a tree structure of linked nodes to perform a longest matching prefix search on the telephone number in response to the request processing logic querying the centralized database.

4. A system for providing information for an international telephone number, the system comprising:
-
a centralized database of telephone characteristics;
a tree structure of multiply-linked nodes in the centralized database, wherein the tree structure serves as a prefix table;
request processing logic that performs operations comprising;
receiving an international telephone number from a user;
in response to receiving the international telephone number, automatically querying the centralized database to obtain location information about the international telephone number; and
in response to obtaining the location information from the centralized database, automatically transmitting the location information in a response to the user; and
a database engine that uses the tree structure to perform a longest matching prefix search on the international telephone number in response to the request processing logic querying the centralized database. - View Dependent Claims (5, 6)

7. A program product for providing information for an international telephone number, the program product comprising:
-
a computer-usable medium; and
computer instructions encoded in the computer-usable medium, wherein the computer instructions perform operations comprising;
receiving an international telephone number from a user;
in response to receiving the international telephone number, automatically querying a centralized database of characteristics to obtain location information about the international telephone number; and
automatically transmitting the location information in a response to the user; and
wherein the operation of automatically querying the centralized database comprises;
automatically consulting a table of prefixes in the centralized database to identify a longest matching prefix for the international telephone number, wherein the centralized prefix database includes prefixes for telephone numbers for multiple nations outside the North American Numbering Plan (NANP); and
in response to identifying the longest matching prefix, automatically consulting a location table in the centralized prefix database to retrieve the location information associated with the longest matching prefix. - View Dependent Claims (8, 9, 10, 11)
