Analysis for the Enhanced Cell Reselection Mechanism in Heterogeneous Wireless System

摘要

This work proposes an enhanced algorithm for cell reselection mechanism in heterogeneous wireless system. A Markov model-based analytical method is proposed to describe system behavior and derive performance metric. The optimal QoS control parameter for the algorithm is derived based on system model and analyzed in numerical results. It is shown that the network performance can be improved by utilizing the proposed algorithm, and the optimal value of QoS control parameter varies according to system traffic condition, which provides insight for network deployment and radio resource management.
