## Title
System and method for automating an unbillable study

## Abstract

A system and method for automating an unbillable study are disclosed. Account information relating to an unbillable call is received from an unbillable study database. At least one database is searched to retrieve records corresponding to the account information. A single report comprising records retrieved from all of the searched databases is generated. The report may be stored in a query-able database.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to researching telephone calls that are unbillable due to a service error. More specifically, the invention relates to an automated system and method for searching at least one database to retrieve records corresponding to an unbillable call.
2. Description of the Prior Art
Interexchange carriers (IXC's) and telephone service providers contract with regional bell operating companies (RBOC's) such as, for example, BellSouth Corporation of Atlanta, Ga., for billing of telephone calls that are placed over the local network of an RBOC. Often, calls are unbillable due to an error in the billing records of the call. Common billing errors include errors such as, for example, a date of call after disconnection of service, a call from an invalid state, an invalid carrier identification, and a toll message with an 800 service guide. Studies are performed by the RBOC to determine why a particular call is unbillable. Existing methods for unbillable telephone call research are both complex and time consuming, thereby raising the operating expenses and consuming the resources of telephone service providers. The expenses and resources devoted to unbillable research may be passed on to consumers in the form of higher rates.
Existing methods for unbillable research are lengthy and cumbersome and comprise conducting individual searches of several databases to find records relating to the unbillable call. These unbillable call databases include disparate databases such as, for example, a Correction Online of Usage Errors investigation database (CLUE), a BellSouth Online Customer Record for Inquiry Systems database (BOCRIS), an Interdepartmental Bill Investigative System database (IBIS), an Loop Maintenance Operating System (LMOS) database, and a guide access database (GADB). Existing unbillable research methods do not enable the production of a single report comprising records retrieved from all the searched databases. Furthermore, existing unbillable research methods do not enable the storage of a single report in a query-able database. Storing a single report in a query-able database would enable the report to be quickly and easily searched, thereby reducing the cost and time required to conduct the unbillable research.
Thus, there is a need in the art for an automated system and method for searching all of the RBOC databases for records corresponding to an unbillable call. Furthermore, there is a need for a system and method that generates a single report comprising records retrieved from all databases, and stores the report in a query-able database.
SUMMARY OF THE INVENTION
The present invention is a system and method for automating an unbillable study. When a call is unbillable due to a service error, a telephone service provider stores account information corresponding to the call in an electronic file such as, for example, a spreadsheet file. The account information may comprise information such as, for example, an account number, a site code, and a code identifying the type of error. Data from the electronic file is imported into an unbillable study database maintained by an RBOC. Information corresponding to an account is then received from the unbillable study database. At least one database is searched to retrieve records corresponding to the account information. A single report of the retrieved records from all of the searched databases is generated. The report may be either printed or viewed on a screen attached to a personal computer. The report may be stored in a query-able database, thereby enabling the report to be quickly and easily searched.

DETAILED DESCRIPTION
A system that meets the above-mentioned objects and provides other beneficial features in accordance with the presently preferred exemplary embodiment of the invention will be described below with reference to FIGS. 1-3. Those skilled in the art will readily appreciate that the description given herein with respect to those figures is for explanatory purposes only and is not intended in any way to limit the scope of the invention. Throughout the description, like reference numerals will refer to like elements in the respective figures.
Billing errors occur when customer billing logic, referred to as a “guide”, fails to match an event to a customer bill. When an error occurs, a telephone service provider may be unable to bill a call to a customer. The telephone service provider may be an RBOC providing service over its local network, an IXC, or another third party providing service over a local network operated and maintained by an RBOC. To find records relating to the unbillable call, the telephone service provider may request a search of at least one unbillable study database 114 maintained by the RBOC. The RBOC conducts an investigation of the searched databases comprising all records relating to the unbillable call to determine which account should be billed. Referring now to FIG. 1, telephone service provider 110 stores account information corresponding to unbillable calls in an electronic file 111 such as, for example, a spreadsheet file. The Telephone service provider 110 provides the RBOC with unbillable records over local area network 112 such that the RBOC may search CLUE database 120, BOCRIS database 122, IBIS database 124, LMOS database 126, and GADB database 128 for records related to an unbillable call. The method for searching databases 120-128 will be discussed in detail below with reference to FIGS. 2-3.
Generally, the account information corresponding to an unbillable telephone call is stored by telephone service provider 110 in an electronic file 111 such as, for example, a spreadsheet file. Account information may comprise information such as, for example, the account number, the site code, and a code identifying the type of error. The error codes are shown in FIGS. 2A and 2B. The electronic file is populated by the telephone service provider when EMI records sent to the RBOC fail to generate billable events and result in errors. Data from the electronic file is imported into an unbillable study database 114 maintained by the RBOC. At least one RBOC database 120-128 is searched to retrieve records corresponding to the account information. A single report of the retrieved records from all of the searched databases is generated. The report may be either printed or viewed on a screen attached to a personal computer. The report may be stored in a query-able database, thereby enabling the report to be quickly and easily searched.
Referring now to FIG. 3, account information corresponding to an unbillable telephone call is stored by the telephone service provider in an electronic file such as, for example, a spreadsheet file at step 310. Account information may comprise information such as, for example, the account number, the site code, and a code identifying the type of error. Common billing errors include errors such as, for example, a date of call after disconnection of service, a call from an invalid state, an invalid carrier identification, and a toll message with an 800 service guide.
At step 312, data from the electronic file is transmitted to the RBOC and is imported into unbillable study database 114. At step 314, information corresponding to an account is received from unbillable study database 114. At step 316, a CLUE database is searched. The initial screens are navigated and relevant records are copied. A single report is populated with the relevant records. At step 318, a BOCRIS database is searched. The initial screens are navigated and relevant records are copied. A single report is populated with the relevant records. At step 320, an IBIS database is searched. The initial screens are navigated and relevant records are copied. A single report is populated with the relevant records. At step 322, an LMOS database is searched. The initial screens are navigated and relevant records are copied. A single report is populated with the relevant records. At step 324, GADB database is searched. The initial screens are navigated and relevant records are copied. A single report is populated with the relevant records. At step 326, the single report of the retrieved records from all of the searched databases is finalized. The report may be either printed and examined in hard copy or viewed on a screen attached to a personal computer. At step 328, the report is maintained in a query-able database, thereby enabling the report to be quickly and easily searched.
While the invention has been described and illustrated with reference to specific embodiments, those skilled in the art will recognize that modification and variations may be made without departing from the principles of the invention as described above and set forth in the following claims. For example, while the invention has been described as being used to search a CLUE database, a BOCRIS database, an IBIS database, an LMOS database, and a GADB database, the invention may be used to search any database comprising records related to an unbillable call. Furthermore, the telephone service provider may connect to the databases over any network such as, for example, the Internet. Accordingly, reference should be made to the appended claims as indicating the scope of the invention.
