Hybrid Data Voice Alarm Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular networks fail to successfully transmit digital alarm signals due to CODECs, preventing the association of alarm signals with two-way voice communication, which is crucial for confirming security events and reducing false alarms.
Innovation Solution
A method that sends alarm notifications via data transmission and associates them with a central station telephone number, allowing for two-way voice communication by selecting an available line number and using voice transmission methods to initiate calls, ensuring successful integration with both data and voice channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital alarm signals are transmitted over cellular voice channel, then two-way voice communication can be established, but the alarm signals are not successfully transmitted due to CODECs
Solution Approach 1:
The patent segments the communication process into two separate channels: a data channel for transmitting alarm signals and a voice channel for two-way communication. The alarm signal is sent via data transmission to establish the alarm condition, and then a separate voice call is initiated to enable two-way communication between the central station and the premises.
Solution Approach 2:
The patent introduces an intermediary association mechanism that links the data channel alarm transmission with the voice channel communication. The system associates the alarm notification received via data transmission with a telephone number, enabling the voice channel to be connected to the same premises without mixing the two communication types.
2Reliability
If alarm signals are sent via data transmission channel, then reliable transmission is achieved, but association with voice communication is lost
Solution Approach 1:
The patent implements a feedback mechanism where the central station receives the alarm signal via data channel, then initiates a voice call back to the premises. The association between the data channel alarm and voice channel is maintained through the callback mechanism, allowing the operator to speak with the premises while the alarm condition is already established through reliable data transmission.
Solution Approach 2:
The patent merges two separate communication channels (data and voice) into a unified alarm notification system. The data channel provides reliable alarm signal transmission, while the voice channel provides two-way communication capability. The system combines these channels by associating them through the central station's callback mechanism, achieving both reliability and versatility.
3Adaptability or versatility
If traditional POTS techniques are used to associate alarm signals with voice calls, then two-way communication is enabled, but the technique does not operate with current cellular networks
Solution Approach 1:
The patent changes the transmission parameter from voice channel to data channel for alarm signal transmission in cellular networks. Instead of attempting to send digital alarm signals over the cellular voice channel (which fails due to CODECs), the system transmits alarm signals via data transmission channels that are compatible with cellular networks, while still enabling voice communication through a separate callback mechanism.

AI summary
A method is presented for providing alarm notification and two-way voice communication for a hybrid data/voice system by sending an alarm from a communication device to a central station receiver via a data transmission method, associating the alarm with a telephone number operating with a voice transmission method, and initiating the two-way voice communication between the communication device and a voice receiver. In one embodiment, associating includes selecting a line number and telephone number, verifying the number's availability, and if the number is available, sending it to the communication device. In another embodiment, associating includes forwarding the alarm from the alarm forwarding service to a receiver, sending a telephone number to the communication device, contacting the telephone number from the communication device, and using a voice transmission method to create a three-way call among the alarm forwarding service, the communication device and the central station.
