Abstract

A system and method for network support that addresses the needs of a cellular phone system which handles large volumes of information. The invention comprises a complex computer network for performing various tasks including data collection and processing, equipment inventory management, customer service, tactical surveillance, trend forecasting, modeling and other interrelated processes. The system incorporates state-of-the-art computer hardware and software into an engineering platform for providing a modular base to accommodate multiple applications as well as to ease integration of future applications.

Claims

1. A system for managing and integrating data in a cellular telephone network comprising:

(a) a computer network including means for collecting real-time data and near real-time data from a plurality of telephone network elements, master server means for receiving and formatting the data, slave server means coupled to the master server means for parsing and reformatting the data;

(b) a plurality of modular task handlers running on the computer network for application by at least one user, the plurality of modular task handlers being easily integrated with future application programs, the modular task handlers including,

(i) means for processing the data,

(ii) on-line relational data base means for storing the data,

(iii) means for managing equipment inventory in response to the processing of the data,

(iv) means for providing customer service in response to the processing of the data,

(v) means for providing tactical surveillance in response to the processing of the data,

(vi) means for providing trend forecasting in response to the processing of the data,

(vii) means for modeling cell sites in response to the processing of the data; and

(c) a plurality of user workstations coupled together and to the master server means and slave server means through the computer network, for providing user access to the plurality of modular task handlers.

2. A system as recited in claim 1 further comprising a graphical user interface for facilitating ease in report generation and system management.

3. A system as recited in claim 1 wherein the telephone network elements comprise telephone switches, cellular sites, microwave equipment, environmental alarm systems and digital cross-connect systems.

4. A system as recited in claim 1 wherein the workstations operate in a multi-tasking window based environment.

5. A cellular telephone network support system for managing and integrating data from telephone switches, cellular phone sites and other related elements, the system comprising:

(a) a relational database having data for providing tactical surveillance, prediction and simulation, and network management;

(b) a workstation configured as a master server for collecting and filtering incoming data from a plurality of network elements, the data representative of billing, traffic alarm, administration, and maintenance information, the master server further preparing updates for the relational database;

(c) a workstation configured as a slave server and coupled to the master server through a computer network, for supplying the relational database with data received from the master server and for storing historical files and providing work-space for recovery and analysis of said historical files; and

(d) a plurality of user workstations, coupled together with the master and slave server through the computer network, the slave server processing database access requests from any of the plurality of user workstations.

6. A network support system as recited in claim 5 wherein the network elements comprise a digital access cross-connect system, a mobile telephone switch, and external alarms.

7. A network support system as recited in claim 5 wherein the master server further comprises a modem for providing dial-up access to the network.

8. A network support system as recited in claim 5 wherein the network has a ring topology.

9. A network support system as recited in claim 5 wherein the network has a star topology.

10. A network support system as recited in claim 5 wherein the network has a bus topology.

11. A network support system as recited in claim 5 wherein the slave server serves as an user workstation during non-peak usage periods.

12. A network support system as recited in claim 5 wherein the tactical surveillance database enables a user to evaluate alarm data from the network elements affected by a disaster and enables a privileged user to make dynamic network adjustments in response thereto.

13. A network support system as recited in claim 12 wherein the disaster is a cell site outage.

14. A network support system as recited in claim 12 wherein the disaster is an unusual shift in traffic patterns.

15. A network support system as recited in claim 5 wherein the network management database further comprises means for traffic forecasting wherein a user inputs a starting date from which to initiate sourcing of historical data and a future date for which it is desired to forecast, and wherein the user inputs a blocking probability percentage wherein a theoretical percentage of the number of trunks that will be blocked at a given time is provided.

16. A network support system as recited in claim 5 wherein the network management database further comprises:

(i) means for generating operational, performance, and maintenance system reports;

(ii) means for creating trend forecasts and cell site modeling of existing cellular phone markets; and

(iii) a graphical user interface for use with the means for generating operational, performance, and maintenance system reports and the means for creating trend forecasts and cell site modeling of existing cellular phone markets, the interface providing access to a system map window, a reports window, a cell site modeling window, a trouble ticketing window, and a system configuration window.

17. A network support system as recited in claim 16 wherein the system configuration window further comprises:

means for configuring a reporting format for standard reports;

means for inputting a total days of a month and days of a week from which data will be sourced to generate the reports;

means for inputting exceptions that will not be included in routine reporting;

means for inputting a specific market name; and

means for inputting a busy hour to choose the busy hour and to default to a value set by a System Administrator in absence thereof.

18. A method for providing support in a cellular telephone network, comprising the steps of:

(a) collecting real-time data and near real-time data from a plurality of telephone network elements;

(b) receiving and formatting the data on a master server connected to the computer network;

(c) parsing and reformatting the data on a slave server coupled to the master server; and

(d) processing the data on the computer network, including the steps of;

(i) managing equipment inventory on the computer network in response to the processing of the data,

(ii) providing customer service on the computer network in response to the processing of the data,

(iii) providing tactical surveillance on the computer network in response to the processing of the data,

(iv) providing trend forecasting on the computer network in response to the processing of the data, and

(v) modeling cell sites on the computer network in response to the processing of the data, wherein the modelling step further comprises the steps of providing data for an existing cell/sector spectrum configuration for system administration utility modeling, supplying auxiliary cell site models to a system administrator, and supplying a default cell site model for use by an user.
