A new effective KeepAlive arithmetic used in embedded application
一种新型有效的KeepAlive算法在通讯系统中的应用

KeepAlive strategy is widely used in communications system.One important reason of using the strategy is that the physical link is unreliable.With KeepAlive strategy,many unexpected exceptions can be avoided.A new effective KeepAlive arithmetic was presented in the paper.The performance of the arithmetic was analyzed and computed,being integrated with 3G Base Station System(3G BSS).The result shows it is of high efficiency and practicability.
