Abstract

A low-power wireless communication device is in a sleep or standby mode of operation for extended periods of time, periodically becoming fully operational and issuing a “check in” message to a base station, thereby inhibiting the ability of the base station to assist in the locating of device, and remotely updating the settings or operational programming of the device much of the time. Upon receipt of a command to locate a misplaced low-power wireless device or to update the device, a base station queues an associated command in a task queue. Upon receipt of a check-in message from an associated low-power wireless device, indicating it is in a fully powered and communicative state of operation, the base station searches its task queue for applicable commands relative to the specific wireless device and executes them via communication with the now fully-operational wireless device.

Claims

1. A method of updating a low-power wireless communication device that is primarily in an uncommunicative mode of operation, the method comprising, at a base unit, the steps of:

receiving a command instructing the low-power wireless communication device to perform at least one of modifying a setting and modifying programming of the low-power wireless communication device;

adding a modify setting command to a task queue if the command received by the low-power wireless communication device instructs the low-power wireless communication device to modify a setting of the low-power wireless communication device;

adding a modify programming command to the task queue if the command received by the low-power wireless communication device instructs the low-power wireless communication device to modify programming of the low-power wireless communication device;

listening for mobile messages from the low-power wireless communication device;

determining if a mobile message received from the low-power wireless communication device is a periodic check-in message;

searching the task queue for modify setting commands and modify programming commands upon receipt of the periodic check-in message;

if a modify setting command is found in the task queue, issuing a modify setting command message to the low-power wireless communication device, prompting the low-power wireless communication device to update at least one parameter or setting with data contained within the modify setting command; and

;

if a modify programming command is found in the task queue, issuing at least one message to the low-power wireless communication device containing replacement or additional programming instructions, prompting the low-power wireless communication device to load and begin execution of the replacement or additional programming instructions.

2. The method according to claim 1, wherein the low-power wireless communication device comprises a mobile unit of a Personal Emergency Response System.

3. The method according to claim 1, wherein the base unit is a component of a Personal Emergency Response System.

4. The method according to claim 1, further comprising, at the low-power wireless communication device, the steps of:

exiting a low-power mode of operation by powering both a transmitter and receiver portion of a transceiver;

issuing the periodic check-in message;

determining if either a modify setting command or a modify programming command has been issued by the base unit;

if a modify setting command has been issued, updating at least one program setting low-power wireless communication device in accordance with the modify setting command; and

if a modify programming command has been issued by the base unit, updating at least a portion of a program of the low-power wireless communication device in accordance with the modify programming command.
