Adaptive Time-to-Trigger Scheme for Optimizing LTE Handover
نویسندگان
چکیده
This paper presents a handover optimization scheme in LTE for a variety of velocities. This scheme adjusts the time-to-trigger parameter based on received signal strength. The proposed algorithm demonstrates a more enhanced performance during a data link failure and ping-pong effect than existing algorithms focusing on a user’s position.

A handover scheme with an adaptive triggering window mechanism in LTE-advanced systems
Brief author introduction:Wang Yu, (1985-),Male, Information Processing. E-mail: [email protected] Abstract: As we know, hard handover scheme is adopted for LTE systems in recent years. In order to improve the performance of the overall system, L3-filter, hysteresis, and time-to-trigger window are investigated. In this paper, we propose a new mechanism with an adaptive time to trigger windo...
متن کاملAlternative Reference Point Based Handover Algorithm for LTE High-speed Rail
A new fast handover algorithm for LTE high-speed rail networks is proposed in this paper. In railway environment, the motion direction and the GPS information of the train can be obtained at any time. Moreover, the neighbor cell that the UE will go through can be precognitive. The above information are utilized to bring forward a fast handover scheme in this paper, which can give a set of alter...
متن کاملA Cost-Based Adaptive Handover Hysteresis Scheme to Minimize the Handover Failure Rate in 3GPP LTE System
We deal with a cost-based adaptive handover hysteresis scheme for the horizontal handover decision strategies, as one of the selfoptimization techniques that canminimize the handover failure rate (HFR) in the 3rd generation partnership project (3GPP) longterm evolution (LTE) system based on the network-controlled hard handover. Especially, for real-time operation, we propose an adaptive hystere...
متن کاملLTE Handover Performance Evaluation
LTE (Long Term Evolution) is a 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 from one cell to another to meet a strict delay requirement while simultaneously keeping network management simple. H...
متن کاملTarget Cell Selection Scheme Using Lms Algorithm for Load Estimation of Neighboring Enbs in 3gpp Lte System
Handover failure probability is one of the important factors to determine the handover performance in cellular radio system such as the 3rd generation partnership project (3GPP) long term evolution (LTE). To minimize the handover failure probability, the Hybird target cell selection (TCS) scheme considering both the received signal strength (RSS) and load information of neighboring evolved Node...
