How to reduce the power consumption of a smart device with limited battery capacity has been treated as an important issue. In this paper, we propose the Module Switching Mechanism (MSM) that consists of the PS scheme and the AWU scheme to reduce the power consumption for dual-mode smart devices. In the PS scheme, the NB-IoT module (i.e., UE_N) is always on, and the LTE transceiver module on/off is controlled by two proposed timers, T_L and T_R, to reduce unnecessary power consumption. In the AWU scheme, the LTE transceiver module can be turned on through NB-IoT module to lower the call dropping probability. We propose the analytical models and conduct simulation experiments to study the performances of MSM in terms of the power saving ratio (R_S) and the call dropping probability (P_B). ? 1967-2012 IEEE. |
