Abstract
This paper mainly studies on reverse link data rate control of CDMA2000 1x EV-DO system. We present the object of reverse link data rate control, aim at this object, combining practice and two basic prevailing control schemes, put forward a new control scheme. In this control scheme, implementation on AT side is described elaborately. First, we transfer the control object to mathematical model by explicitly design utility function form of some type of wireless data services, then, in order to adapt to EV-DO system, we transform this model to an equivalent distributed model on AT side, after that, we utilize Lagrangian method to obtain solution of the distributed model, and prove that this solution satisfies the integrated problem’s constraints put forward by the control object, we also design the MAC protocol based on this algorithm. At last, we validate availability and efficiency of the algorithm through experiment and simulation.
