碩士 === 國立交通大學 === 電信工程研究所 === 103 === Recently, the amount of the applications running on smart phones grows up rapidly, leading to growth in traffic volume and diversity in the cellular network. In the uplink traffic, these applications generate the background traffic packets, which are usually scattered in time and with small size, to update the information even when the user is not interactive with them. This may cause frequent transition between the RRC idle state and RRC connected state or what’s worse, keep an UE staying in the connected state all the time. It makes our smart phones consume more energy. In this thesis, we propose a shaping scheme to accumulate background traffic packets and transmit them together for the purpose of decreasing the energy consumption. Finally, the simulation results show that the shaping scheme can reduce 30% consumed energy.
