Abstract

A method for electronic communications comprises transmitting an electronic text message from a sender to a receiver, starting a sender timer when the text message is transmitted that monitors an initial time period to accept a response message from the receiver, and starting a receiver timer when the text message is received that monitors an initial time period to respond. If a STANDBY message is selected after the text message is received, an automatic timing delay is initiated to send the STANDBY message. The STANDBY message is transmitted when the automatic timing delay has reached a predetermined timing threshold. The receiver timer is restarted when the STANDBY message is transmitted to give the receiver an additional time period to respond. The sender timer is restarted when the STANDBY message is received to give the sender an additional time period to accept a response message from the receiver.

Claims

1. A method for electronic communications, the method comprising:

transmitting an electronic text message from a sender to a receiver;

starting a sender timer when the text message is transmitted that monitors an initial time period to accept a response message from the receiver;

starting a receiver timer when the text message is received that monitors an initial time period to respond;

if a standby function is manually selected after the text message is received, initiating an automatic timing delay to send a standby message;

transmitting the standby message when the automatic timing delay has reached a predetermined timing threshold;

restarting the receiver timer when the standby message is transmitted to give the receiver an additional time period to respond; and

restarting the sender timer when the standby message is received to give the sender an additional time period to accept a response message from the receiver.

2. The method of claim 1, wherein the sender is an air traffic controller or a pilot.

3. The method of claim 2, wherein the receiver is an air traffic controller when the sender is a pilot.

4. The method of claim 2, wherein the receiver is a pilot when the sender is an air traffic controller.

5. The method of claim 1, wherein the electronic text message is a controller pilot data link communication message.

6. The method of claim 1, wherein if a response message is not sent to the sender by the receiver before the additional time period to respond expires, any subsequent response message is disabled.

7. The method of claim 1, wherein if a response message is not received by the sender before the additional time period to accept a response message expires, the response message will not be accepted.

8. A method for electronic communications in a network, the method comprising:

(a) receiving an electronic text message;

(b) starting a response timer;

(c) monitoring whether the response timer has expired;

(d) if the response timer has not expired, determining whether a response message has been transmitted;

(e) if a response message has not been transmitted, repeating (c) and (d) until a standby function is manually selected that initiates an automatic timing delay in sending a standby message;

(f) when the standby function is selected, determining whether the response timer has reached a predetermined timing threshold;

(g) if the response timer has not reached the predetermined timing threshold, determining whether a response message has been transmitted;

(h) if the response message has not been transmitted, repeating (f) and (g) until the predetermined timing threshold is reached or the response message is transmitted;

(i) if the response timer has reached the predetermined timing threshold, transmitting the standby message and restarting the response timer;

(j) monitoring whether a response message has been transmitted;

(k) if a response message has not been transmitted, determining whether the response timer has expired;

(l) if the response timer has not expired, repeating (j) and (k) until the response message is transmitted or the response timer has expired; and

(m) if the response timer has expired without the response message being transmitted, disabling any subsequent response message from being transmitted.

9. The method of claim 8, wherein the electronic text message is received by a pilot or an air traffic controller.

10. The method of claim 8, wherein the predetermined timing threshold is automatically varied as a function of network performance.

11. The method of claim 8, wherein the predetermined timing threshold is automatically varied based on a round trip message time between a sender computer and a receiver computer.

12. The method of claim 11, wherein the round trip message time is calculated as a difference between a message transmission time and a time of reception of a response message.

13. The method of claim 8, further comprising:

setting a default value for the predetermined timing threshold;

montioring a round trip message time;

determining whether the round trip message time is within a first range;

if the round trip message time is within the first range, setting the predetermined timing threshold to a first value that is less than the default value, and continue monitoring the round trip message time;

if the round trip message time is not within the first range, determining whether the round trip message time is within a second range;

if the round trip message time is within the second range, setting the timing threshold to a second value that is less than the first value, and continue monitoring the round trip message time;

if the round trip message time is not within the second range, determining whether the round trip message time is within a third range;

if the round trip message time is within the third range, setting the timing threshold to a third value that is less than the second value, and continue monitoring the round trip message time;

if the round trip message time is not within the third range, determining whether the round trip message time is within a fourth range; and

if the round trip message time is within the fourth range, setting the timing threshold to the default value, and continue monitoring the round trip message time.

14. The method of claim 8, wherein the method is implemented as part of communication protocols for a future air navigation controller pilot data link communication (CPDLC) system.

15. The method of claim 8, wherein the method is implemented as part of communication protocols for an aeronautical telecommunication network CPDLC system.

16. A computer system, comprising:

at least one processor; and

17. The computer system of claim 16, wherein the computer system comprises a communication management function, a communication management unit, a flight management computer, or an air traffic control computer.

18. A computer program product, comprising:

a computer readable medium having instructions stored thereon executable by a processor to carry out the method of claim 8.

19. A system for electronic communications, the system comprising:
