Mobility management has become an important factor in 4G networks due to the integration of multiple network access methodologies such as WLAN. This paper is to introduce a Vertical HandOver (VHO) algorithm between Wireless LANs (WLANs) and LTE mobile networks. The proposed algorithm is based on the fuzzy control theory and takes into consideration power level, subscriber velocity, and target cell load instead of only power level in traditional algorithms. Simulation results show that network performance in terms of number of handovers and handover occurrence distance are improved.
