Alarm System Event Data Delivery via Private Telecommunications Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security alarm systems relying on the Public Switched Telephone Network (PSTN) lack flexibility in establishing voice channels for alarm event data and audio communication, limiting service providers' ability to manage connections and leverage the benefits of Voice over IP (VoIP) technology.
Innovation Solution
A method and system that detect alarm events, communicate data to a private telecommunications switch, evaluate service parameters, and establish a Public Switched Telephone Network (PSTN) voice channel to a central alarm monitoring station, bridging it to create a voice channel between the alarm system and the monitoring station, using a message processing gateway and private telecommunications switch to manage connections and ensure service parameters are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional alarm systems use PSTN to establish voice channels automatically upon alarm events, then alarm event data and audio can be communicated reliably, but service providers lack flexibility to evaluate and control connection establishment
Solution Approach 1:
The patent introduces a message processing gateway as an intermediary component between the alarm system and the central monitoring station. This gateway receives alarm event data from the alarm system, evaluates service parameters, and determines whether to establish a voice channel based on provider policies. The gateway acts as a mediator that enables service providers to control and evaluate connections without adding significant complexity to the alarm system itself.
2Adaptability or versatility
If alarm systems establish voice channels automatically upon alarm events, then communication is initiated quickly, but service providers cannot intervene or evaluate service parameters before connection establishment
Solution Approach 1:
The message processing gateway performs preliminary evaluation of service parameters before the voice channel is established. When an alarm event occurs, the gateway first receives and evaluates the alarm event data against service parameters, then decides whether to proceed with voice channel establishment. This preliminary action ensures service provider control is maintained without significantly delaying the overall response time.
3Reliability
If PSTN is used for alarm system communications, then reliable voice channel establishment is achieved, but flexibility and speed of connection management are limited
Solution Approach 1:
The patent segments the connection management function into separate components: the alarm system generates alarm event data, the message processing gateway evaluates service parameters and makes connection decisions, and the PSTN provides the actual voice channel. This segmentation allows each component to specialize in its function, maintaining PSTN reliability for voice transmission while adding flexibility through the gateway's evaluation and control capabilities.

AI summary
Delivery of alarm system event data and audio. In certain aspects, a method for delivery of alarm system event data is described, including communicating alarm event data from an alarm system to a private telecommunications switch. In turn, the alarm event data may be communicated to a message processing gateway. The message processing gateway evaluates service parameters of the alarm system and, in certain cases, instructs the private telecommunications switch to contact a central alarm monitoring station if certain service parameters are met. In additional aspects, private telecommunications switch opens a voice channel between the private telecommunications switch and the central alarm monitoring station and communicates the alarm event data. Additionally, in response to a determination that a voice channel between the private telecommunications switch and the central alarm monitoring station remains open, the private telecommunications switch may also bridge the voice channel to the alarm system.
