The probability of a time out and the resulting waste of channel capacity in a communication system is decreased by controlling the length of the time out period so as to minimize the number of time outs that occur. The length of the time out is based on the sum of the average channel delay and four times the deviation in the channel delay. A delay is introduced into the communication channel so as to increase the deviation in the channel delay. This results in an increase in the length of time required for a time out. As a result, the number of time outs is drastically decreased which in turn decreases the number of wasteful ramp up times that results in a more efficient use of channel capacity.

The invention claimed is: 1. A method of time out control in a wireless communication system, comprising: inserting channel delay in data being carried over a communication channel to increase a length of time required for a time out and decrease a number of ramp up times, wherein said inserting includes inserting said channel delay into an acknowledge message to be transmitted over said communication channel in response to a received data transmission. 2. The method of claim 1, wherein said inserting includes inserting the channel delay into data to be transmitted by a base station over said communication channel. 3. The method of claim 2, further comprising: controlling an amount of said channel delay inserted in said data. 4. The method of claim 3, wherein said controlling includes: monitoring a plurality of acknowledge message received in response to said data transmitted with said channel delay, the plurality of acknowledge messages including said acknowledge message, and determining said channel delay for insertion based on a delay observed between transmission of said data and reception of the plurality of acknowledge messages. 5. The method of claim 1, further comprising: controlling an amount of said channel delay inserted in said acknowledge message. 6. The method of claim 5, wherein said controlling includes: adding said channel delay to said acknowledge message so as to increase an observed channel delay as observed by a receiver of the acknowledge message. 7. The method of claim 1, wherein said inserting includes adding said channel delay to said communication channel at a mobile station to control the time out for data transmission between said mobile station and an application. 8. A base station configured for controlling time out in a wireless communication system, comprising: means for transmitting and receiving data over a communication channel; means for inserting channel delay into data to be transmitted over said communication channel to increase a length of time required for a time out and decrease a number of ramp up times; at least one buffer adapted for adding channel delay in said data to be transmitted; and a processor monitoring acknowledge messages received in response to said data transmitted with said channel delay, and determining a desired channel delay based on the received acknowledge messages. 9. The base station of claim 8, wherein said processor modifies the depth or amount of the channel delay added by the buffer until a desired delay is measured as seen by a delay in receiving said acknowledge messages. 10. The base station of claim 8, wherein said buffer is one of a shift register and a cyclically addressed memory. 11. A mobile communication device configured for controlling time out in a wireless communication system, comprising: means for transmitting and receiving data over a communication channel; means for inserting channel delay in said communication channel to control time out for data transmission and decrease a number of ramp up times between said mobile communication device and an application; at least one buffer adapted for adding channel delay in data to be transmitted by the device; and a processor controlling a depth of said at least one buffer to control said channel delay. 12. The device of claim 11, wherein said at least one buffer is one of an outgoing buffer and an acknowledge buffer.
