Abstract

An electronic communication device includes a buffer and a controller. The buffer stores characters as they are being input by a user. The controller transmits the stored characters over a network when the number of characters stored exceeds a threshold. The controller also dynamically adjusts the threshold time period.

Claims

1. An electronic communication device comprising:

a buffer configured to store characters of a message as they are being input by a user; and

a controller configured to transmit the stored characters over a network, prior to completion of user input of the message, in response to detecting that the number of characters stored exceeds a threshold, and to dynamically adjust the threshold.

2. The device of claim 1 wherein the controller is configured to dynamically adjust the threshold based on packet size and packet overhead of the network.

3. The device of claim 1 wherein the controller is configured to dynamically adjust the threshold based on latency and bandwidth of the network.

4. The device of claim 1 wherein the controller is configured to dynamically adjust the threshold based on the user'"'"'s typing speed in inputting the characters.

5. The device of claim 1 wherein the controller is configured to dynamically adjust the threshold based on processing resources available on the device.

6. The device of claim 1 wherein the controller, after transmitting the stored characters, clears the stored characters from the buffer and checks for a next inputted character of the message.

7. A method comprising:

storing characters of a message as the characters are being input by a user;

transmitting the stored characters over a network, prior to completion of user input of the message, in response to detecting that the number of characters stored exceeds a threshold; and

dynamically adjusting the threshold.

8. The method of claim 7 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on packet size and packet overhead of the network.

9. The method of claim 7 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on latency and bandwidth of the network.

10. The method of claim 7 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on the user'"'"'s typing speed of inputting the characters.

11. The method of claim 7 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on processing resources available on the device.

12. The method of claim 7 wherein said transmitting of the stored characters is followed by clearing the stored characters from a buffer that the characters were stored in and checking for a next inputted character of the message.
