System and method for minimizing the amount of data being sent on a network for supervised security systems
First Claim
1. A method for limiting the amount of data transmitted between a security system and a monitoring station within a heartbeat time interval comprising:
- transmitting a first heartbeat signal from a controller within a security system to the monitoring station;
waiting a given time period for an acknowledgement signal to be sent from the monitoring station to the controller;
determining whether or not an acknowledgement signal was received by the controller in response to the first heartbeat signal within the given time period;
if an acknowledgement signal is received by the controller in response to the first heartbeat signal within the given time period, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the controller to the monitoring station; and
transmitting a second heartbeat signal from the controller to the monitoring station within the heartbeat time interval if an acknowledgement signal is not received by the controller within the given time period from when the first heartbeat signal was transmitted to the monitoring station;
wherein the first heartbeat signal is transmitted from the controller to the monitoring station over a first communication network and the second heartbeat signal is transmitted from the controller to the monitoring station over a second communication network that is different from the first communication network.

Abstract
A system and method are disclosed for communicating heartbeat signals representative of the condition of a security system to a monitoring station. A controller is provided that transmits a heartbeat signal to a monitoring station within a given time period and awaits an acknowledgement signal from the monitoring station. If an acknowledgement signal is received within a time interval from the transmission of the heartbeat signal, then the time period is reset and another heartbeat signal is not sent until the next time period. If an acknowledgement signal is not received by the controller within a few seconds of transmitting the heartbeat signal, then another heartbeat signal is sent from the controller to the monitoring station. Heartbeat signals are only transmitted from the controller if an acknowledgement signal is not received from the monitoring station. In this manner, the amount of data sent over a communication link is reduced.

11. A method for limiting the amount of data transmitted between a security system and a receiving station within a time period comprising:
-
transmitting a first heartbeat signal from a communicator within a security system to the receiving station within a heartbeat time interval; waiting for an acknowledgement signal to be sent from the receiving station to the security system within the heartbeat time interval; determining whether or not an acknowledgement signal was received by the security system in response to the first heartbeat signal within the heartbeat time interval; if an acknowledgement signal is received by the security system in response to first the heartbeat signal within the heartbeat time interval, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the communicator to the receiving station; and transmitting a second heartbeat signal from the communicator to the receiving station within the heartbeat time interval if an acknowledgement signal is not received by the security system within the given time period from when the first heartbeat signal was transmitted to the receiving station; wherein the first heartbeat signal is transmitted from the communicator to the receiving station over a first communication network and the second heartbeat signal is transmitted from the communicator to the receiving station over a second communication network that is different from the first communication network. - View Dependent Claims (12, 13)

14. A system for transmitting heartbeat signals for use with a system in a monitored building comprising a plurality of sensors, and a controller communicating with each of the plurality of sensors, a receiver at a monitoring station communicating with the controller, and a machine-readable storage medium encoded with a computer program code in the controller such that, when the computer program code is executed by a processor, the processor performs a method comprising:
-
transmitting a first heartbeat signal from a controller within a security system to the monitoring station within a heartbeat time interval; waiting for an acknowledgement signal to be sent from the monitoring station to the controller within the heartbeat time interval; determining whether or not an acknowledgement signal was received by the controller in response to the first heartbeat signal within the heartbeat time interval; if an acknowledgement signal is received by the controller in response to the first heartbeat signal, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the controller to the monitoring station; and transmitting a second heartbeat signal from the controller to the monitoring station within the heartbeat time interval if an acknowledgement signal is not received by the controller within the given time period from when the first heartbeat signal was transmitted to the monitoring station; wherein the first heartbeat signal is transmitted from the controller to the monitoring station over a first communication network and the second heartbeat signal is transmitted from the controller to the monitoring station over a second communication network that is different from the first communication network. - View Dependent Claims (15, 16, 17, 18)
