摘要：

In order to reduce the energy consumption and increase the response speed of the mobile stations in Long Term Evolution (LTE) communication technology, a novel power saving strategy is proposed in Discontinuous Reception (DRX) with sleep-delay mechanism. Considering that the system buffer is finite in practice, a multiple-vacation queuing model with a sleep-delay period and a waking-up procedure is built. Using the methods of embedded Markov chain and supplemental variable, the formulas of the system block ratio, the energy saving ratio and the latency of data frames are given. Combining the numerical experiments with analysis and simulation, the trade-off between different performance measures is investigated. Finally, the time length of the sleep-delay period and the buffer capacity in DRX are optimized. The results of this research have potential applications in the improvement and optimization of the energy saving strategy in wireless communication networks. ©, 2015, Jilin Daxue Xuebao (Gongxueban)/Journal of Jilin University (Engineering and Technology Edition).
