摘要: This paper investigates the discontinuous reception (DRX) mechanism of Universal Mobile Telecommunications System (UMTS). DRX is exercised between the network and a mobile station (MS) to save the power of the MS, which is controlled by two parameters: the inactivity timer threshold and the DRX cycle. Analytic model is proposed to study the effects of these two parameters on output measures including the expected queue length, the expected packet waiting time, and the power saving factor. Our study quantitatively shows how to select appropriate inactivity timer and DRX cycle values for various traffic patterns.
