Impact of DRX parameters on user equipment power saving and delay reduction in LTE networks

The growing need for the access of user equipment’s (UE) has increased the necessity to investigate the power consumption in the switching process and to develop a method to reduce the power loss incurred in the system. Discontinuous reception mechanism (DRX) is a methodology proposed in Long Term Evolution (LTE) networks to achieve this desired effect. Although DRX mechanism introduces latency in the system, the power that can be saved in active and background traffic is comparatively good. This work focuses on power saving in UE and delay introduced in the process. Moreover, scheduling the DRX parameters can result in optimization of delay reduction and power. Thereby, better quality of service and enhanced lifetime of the UE can be achieved.
