Power management mechanisms (PMMs) inherently have a tradeoff between the energy consumption and delay. In this letter, we analyze an active-idle state transition mechanism for power-saving in mobile stations by considering the general traffic pattern of smartphones, which consists of uplink request packets and downlink bursty data. We derive closed-form solutions of both the energy consumption and activation delay, and characterize their tradeoff relationship. The results show that the tradeoff curve is linear and its slope is not affected by the PMM's operational parameters or the traffic arrival rate.
