ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a computer program that can create new wireless databases from all or parts of one or more existing wireless databases containing data information for the operation of data and voice audio telecommunication switches.
DESCRIPTION OF THE PRIOR ART
The configuration of telecommunication switches usually occurs in at least three environments. First, during the testing of switch hardware and software, a laboratory switch is configured to the requirements established for the test. Second, when a switch is sold to a customer, the switch is configured to the customer's specifications. Third, when a switch experiences a full failure, it often requires reconfiguration of the databases supporting the failed switch or configuration of new databases for an emergency backup switch or replacement switch. Normally, the configuration of telecommunication switches during these three environments requires the manual input of thousands and possibly millions of records of information. This process is extremely time consuming and can take weeks or months to complete.
In the first environment, telecommunication companies continually test new versions of switch software, peripheral devices and other hardware devices during the life of a telecommunication switch. When testing software or hardware, switch engineers design different operating environments to establish operating parameters of the new software or hardware. Data engineers manually input data to configure the operation of the switch for the designed test. Usually, the configuration of the testing environment is performed on a data build machine (computer). The configuration of the switch to simulate the desired testing operational conditions often involves retesting archived configurations or modified archived configurations. Otherwise, the testing configuration is accomplished by manual data entry.
In the second environment, telecommunication switches sold to customers are configured based on the customer's intended operational conditions and equivalent. Usually, the configurations for new switches are manually built new data configurations without relying on existing database configurations. However, the configuration of the features, switching software and hardware is often adopted from other existing configurations.
The third operational environment is recovery of the switch after the switch has experienced a failure. These failures can result from equipment failure to natural disasters such as earthquakes, hurricanes or fires. Recovery of the failed switch sometimes requires the installation of an emergency backup switch. The emergency backup switch requires database configurations that replicate the databases in the damaged switch. Normally, the configuration of the emergency backup switch requires manual, time consuming input of data that will support specific customer features and routing of calls on the emergency backup switch. Having the ability to configure the telecommunication switch by transferring existing data information from known databases into new databases by automating the manual tasks of data entry would save considerable time, money and significantly improve productivity. In addition, instant access to many different switching systems is a critical task that currently requires many hours or days of research and manual browsing. A need exists for a robust process to automatically replace the current manual method data entry to configure wireless data for telecommunication switches.
SUMMARY
In order to automate the current manual data entry process of engineering GSM wireless configuration databases, the computer program of this invention establishes a new database structure and mines source databases to load source database wireless data into the new wireless database structure. The computer program is capable of searching for the desired data and automates many of the tasks for configuring a new wireless database from the source databases. This eliminates the requirement for manual data entry for configuring new wireless databases for telecommunication switches.
This computer program is multifunctional allowing for the browsing of all wireless databases prior to the configuration. Once the target source wireless databases are determined, the computer program creates a new data directory structure and selectively copies all or part of the data from the source wireless database into the new database. The user selects the “C” interfaces, and the mobile switching center subscriber services. The computer program builds the home location register. If the mobile switching center is included in the configuration, the user determines the “A” interface, the base station interface, the location areas, the geographical locations, the short message service, operations maintenance and billing center interfaces and the computer program builds the visitor location register, the equipment identity register, the dialed digit strings, the call routing, measurement and billing services. If the mobile switching center is not included in the configuration, the network configuration is run. The computer program builds the signaling connection control part and the destination database.
This invention provides accurate and timely customer information, significantly decreases the time interval for engineering a new wireless configuration database, decreases the research and data entry time, decreases the interval for lab planing and project management, improves database integrity, provides a cleaner wireless database, reuses existing wireless data eliminating double data entry, reuses some existing software code, can use preexisting tools, and provides a platform for future growth and expandability. By accomplishing these tasks, the wireless telecommunication switch manufacturer or wireless telecommunication switch operator saves time, money and decreases time-to-market product and service schedules.
