In order to save the UE’s battery Life, discontinuous reception(DRX) is specified to reduce the UE’s power consumption, DRX allow the UE to turn off RF module when there is no data need to transfer. This work focus on analysis DRX mechanism with different RRC states, we use a simple numerically analytical to model this. We divided the time period for power-saving operation into several independent parts to derive the power consumption and the transmission delay. To analysis the power advisably, we introduce the real power consumption through the power model. We evaluate the performance that the UE is more power effectively when enters RRC IDLE in lower arrival rate, and there is trade-off between the power and the transmission delay.
