摘要

One of the main goals of LTE is to provide seamless and fast handover from one cell to another to meet a strict requirements. Hence, the decision of handover is a critical part in the design process of handover. The design of an efficient and successful handover requires a careful selection of handover (HO) parameters and the optimal setting of these. In this paper a new handover optimization algorithm for long term evolution (LTE) network based on fuzzy logic is presented. It consists of finding the optimum handover margin (HOM) required for handover process and also finding appropriate time-to-trigger (TTT) to perform a success handover using fuzzy logic. The proposed handover optimization technique is evaluated and compared with the four well-known handover algorithms and achieves minimum average number of handover per user and also have maximum throughput than the self-optimization technique.
