Mobility robustness optimization in wireless mobile networks

LTE (Long Term Evolution) is the fourth generation cellular network technology that provides improved performance related to data rate, coverage and capacity compared to legacy cellular systems. In this context, one of the main goals of LTE is to provide fast and seamless handover (HO) from one cell to another to meet a strict delay requirement while simultaneously keeping network management simple. Hence, the decision to trigger handover is a crucial component in the design process, since the success and the efficiency, to a large extent, depends on the accuracy and timeliness of the decision.
