“…During the early implementation of DRX in the 3G mobile network, [9] developed analytical and simulation models to study the DRX performance mainly for Poisson traffic. In this study, a novel semi-Markov process to model the 2-step UMTS DRX with bursty packet data traffic was proposed, and the study also investigated the effects of the two DRX parameters on output measures including the power saving factor and the mean packet waiting time.…”

“…DRX's power saving performance and its behavior has been studied and described over the past few years in both simulated and analytical works [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]. The first analytical model for the DRX operation was described in the predecessor of the 3GPP LTE-A, Universal Mobile Telecommunications System (UMTS) [17,8].…”

“…The model assumes that packet arrival intervals and transition times follow exponential and general distribution, respectively. Thereafter, several studies [6,7,9,12] have extended the model and developed standard 3-state DRX models. First, the probabilities that the number of packets arrives depending on the UE's power saving operation during one single packet being served was derived.…”

LTE and LTE-Advanced mobile technologies have integrated discontinuous reception (DRX) power saving method to optimize the power consumption at the user equipment (UE). The DRX method was proposed by the 3rd Generation partnership Project (3GPP), and since then, the traffic behavior has been analyzed in several studies with a standard 3-state DRX model to describe the trade-off between power saving and delay. In this paper, we presented a novel 4-state and 5-state 3GPP LTE DRX mechanisms. The proposed mechanisms were developed by augmenting (an) active state(s) to deep and/or light sleep cycle of standard 3-state DRX for handling a small burst of packets, thereby bypassing the process of returning to the timer-dependent active mode. We have generated analytical models using a semi-Markov process for bursty packet data traffic and evaluated these augmented DRX mechanisms against a standard 3-state DRX method. Overall, the analytical results from varying timing parameters showed that our augmented DRX (both 4-state and 5-state) improved power saving factor (ranging between 1% and 8%) and reduced delay (ranging between 20% and 60%) compared to the standard 3-state DRX. Furthermore, the magnitude of improvement for both delay and power-saving was somewhat greater in 5-state than 4-state.

“…In [8], a variant of the M/G/1 queues was presented in order to explore the performance of the DRX. The closed-form equations are derived for the output measures based on the Poisson assumption, and a novel semi-Markov process is proposed to model the DRX in [7]. With [6] provided a comparison of the energy saving mechanisms of 3GPP and 3GPP2.…”

Abstract-Long Term Evolution (LTE) of 3GPP provides high bandwidth for data transfer. Having high bandwidth transfer will exhaust the user equipment (UE)'s battery power quickly. To extend the UE's battery lifetime the 3GPP standards for LTE support Enhanced Discontinuous Reception (DRX). The DRX allow an idle UE to save battery by turning off the radio receiver for a predefined period. Since the Transmission Time Interval (TTI) is related to the size of the data block passed from the higher networks layers to the radio link layer, the DRX scheduler should vary the resource allocation of each user basis on TTI. In this paper, we have evaluated the influences of the TTI sizes as well as the effects of LTE DRX Light and Deep Sleep mode on power consumption for Voice and Web traffic.

“…One of the earlier research works performed on the DRX mechanism was [1] where a 4 state semi-Markov model was presented and verified against simulation experiments, for the universal mobile telecommunications system (UMTS) power saving mechanism using traffic with exponentially distributed inter-packet times. Following on this work a number of papers, amongst them [2]- [8] has been published with similar approaches using at least 3 state semi-Markov models with different types of traffic models.…”

Abstract-LTE/LTE-A are emerging communication technologies on the way towards 5G telecommunication systems. Ubiquitous adoption of connectivity in between different kinds of sensors, wearable devices and other low-power equipment raises an importance of the energy-efficient wireless communications. In LTE/LTE-A the Discontinuous Reception Mechanism (DRX) aims at power saving of User Equipment (UE) devices. In the paper we present an analysis of DRX, which is novel in two dimensions. First, our analytical approach is different to existing ones due to the use of Markov chain instead of the semi-Markov ones. Secondly, along with the generic traffic models we also analyze the efficiency of DRX for military training application systems, what has not been done before. We suggest few practical recommendations regarding the DRX parameters tuning also.
