碩士 === 國立交通大學 === 電信工程研究所 === 103 === In recent days, the traffic in wireless network has been much more unpredictable and diverse since there are various applications running on smartphones. In the uplink traffic, the small amount of packets widely dispersed on time mainly generated by application background refresh may awake radio resource controller (RRC) from idle state to connected state, or, even worse, force RRC to stay in the idle state, to transmit the data frequently which cost massive power consumption when user is not using the smartphone actively. To reduce the time RRC stays in connected state and to concentrate the uplink traffic generated by application background refresh in user equipment, we analyze and compare three shaping schemes which transmit accumulated data together and propose two of them as the solutions for different scenarios to achieve lower power on ratio and transmit efficiency. Additionally, we analyze the performance of the proposed shaping schemes via the real trace of background traffic provided by Intel, and the analytical results are verified through the simulations.
