Security Central Station Caller ID Mismatch Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security central stations face challenges in contacting security systems when the telephone number of the protected premises changes due to ownership changes, service provider changes, or number reassignment, leading to difficulties in retrieving information or configuring the security equipment.
Innovation Solution
A method where the security central station compares the ten-digit caller telephone number with the ten-digit account number, detecting mismatches and alerting for investigation, utilizing caller ID or ANI services to update the account number as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the security central station uses a fixed ten-digit account number to monitor security systems, then the system can maintain stable record-keeping and data retrieval, but the system becomes unable to adapt when the telephone number of the protected premises changes
Solution Approach 1:
The patent implements a dynamic account number system where the previously fixed ten-digit account number is replaced by a variable field that can accommodate both old and new telephone numbers. This allows the system to adapt to number changes while maintaining reliable record-keeping through the dynamic update mechanism.
Solution Approach 2:
The system changes the parameter of the account number from a static fixed value to a dynamic variable that can be updated. By allowing the account number field to change based on new telephone numbers while maintaining the ability to retrieve historical data, the system resolves the contradiction between adaptability and reliability.
2Productivity
If the security central station monitors a large number of individual security systems over many telephone lines, then the system can provide comprehensive coverage, but the complexity of managing and updating account information increases
Solution Approach 1:
The patent implements a self-service mechanism where the security system automatically detects telephone number changes and triggers updates to the account number in the central station database. This automated process reduces the manual complexity of managing account information across numerous security systems while maintaining comprehensive monitoring capability.
Solution Approach 2:
The system uses feedback from the security systems to automatically detect when telephone number changes occur. This feedback mechanism allows the central station to receive notifications of changes and automatically update records, reducing the manual complexity of managing large numbers of accounts while maintaining comprehensive system coverage.

AI summary
A security central station monitors a plurality of individual subscriber security systems installed in residential or commercial accounts. Each security system at an account is programmed to periodically place a telephone call to the security central station receiver, and then to send a signal to the security central station receiver over the placed telephone call. The ten digit telephone number of the account is programmed into the security central station as the ten digit account number of record. When the signal sent by the security system is received by the security central station receiver, the security central station compares the ten digit caller telephone number with the ten digit account number of record. Normally, the ten digit caller telephone number will match the ten digit account number. However, a mismatch between the two ten digit numbers indicates to the security central station that the telephone number of the account premises protected by the security system has been changed, and alerts the security central station to investigate the matter further.
