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 a pause in the input of characters exceeds a threshold time period. The controller also dynamically adjusts the threshold time period.

Claims

1. An electronic communication device comprising:

a buffer configured to store user input characters for an electronic message; and

a controller configured to transmit the stored user input characters over a wireless network prior to input completion of the electronic message when a pause in the input of characters exceeds a dynamically adjustable threshold time period,

the controller further configured to dynamically adjust the threshold based on a typing speed of the user input characters.

2. The device of claim 1 wherein the controller is configured to dynamically adjust the threshold based on at least one of a transmission packet size and a transmission packet overhead.

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

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

5. A method comprising:

storing characters for an electronic message as the characters are being input to a wireless communication device by a user;

transmitting the stored characters over a wireless network before the electronic message has been completely input when a pause in the input of characters exceeds a threshold; and

dynamically adjusting the threshold based on the user'"'"'s typing speed in inputting the characters.

6. The method of claim 5 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on packet size and packet overhead of the network.

7. The method of claim 5 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on latency and bandwidth of the network.

8. The method of claim 5 wherein the dynamically adjusting step includes dynamically adjusting the threshold based on processing resources available on the device.
