Abstract

An electronic communication system provides text or voice messages to remote receiving devices, such as cell phones or PDA'"'"'s. The remote receiving devices are equipped with velocity sensors, or position sensors from which velocity may be inferred. The remote receiving devices periodically report a velocity or current position to an alert signal control node of the communication system. The alert signal control node determines a most recent-determinable velocity for each receiving device before transmitting a message alert signal. If the velocity exceeds a predetermined threshold, the alert signal may be delayed until the velocity drops below the threshold. The system may be operated as a safety measure to prevent reception of distracting alert signals while driving, thereby silencing messaging devices at appropriate times.

Claims

a wireless receiver;

a processor coupled to receive message signals from the wireless receiver;

means for coupling a velocity sensor to the processor;

a memory coupled to the processor;

2. The portable messaging device of claim 1, wherein the program instructions are further configured for re-enabling audible alert signaling for incoming messages, in response to determining, using the velocity sensor coupled to the processor, that the current velocity of the portable messaging device is not greater than the defined threshold.

3. The portable messaging device of claim 1, wherein the program instructions are further configured for obtaining message priority information from incoming messages, and selectively disabling the audible alert signaling additionally in response to determining, for each one of the incoming messages, that the message priority is not higher than a defined priority threshold.

5. The portable messaging device of claim 4, wherein the receiver comprises a frequency-hopping spread spectrum receiver.

6. The portable messaging device of claim 1, wherein the means for coupling a velocity sensor to the processor comprises a GPS receiver connected to the processor and configured to receive a GPS locating signal.

7. The portable messaging device of claim 6, further comprising a timer coupled to the processor.

8. The portable messaging device of claim 7, wherein the program instructions are further configured for determining whether the current velocity using the GPS locating signal and a time signal from the timer.

15. The method of claim 11, further comprising reading a priority level assigned to the incoming message, and preventing the portable wireless messaging device from emitting any audible alert signal only if the priority level is lower than a defined level.

16. A computer-readable medium encoded with instructions that, when executed by a processor, cause a portable wireless device to:

determine a current velocity of the portable wireless device; and

disable an alert signal of the portable wireless device, in response to determining that the current velocity of the portable wireless device is greater than a defined threshold.
