Nowadays, everybody use handphones to communicate or surf the internet. In order to cope with the users demand and capacity, Long Term Evolution (LTE) has been introduced as the new technology which is consists of macrocell, picocell and femtocell heterogeneous networks. The deployment of this femtocell will help to offload traffic in macrocell LTE heterogeneous network. However, this deployment has negative impact on the handoff performance especially when mobile devices roam across heterogeneous access networks. Therefore; this research presents frameworks to minimize the unnecessary handover for femtocell to femtocell and macrocell to femtocell in LTE heterogeneous network. Two parameters are used which are speed and handoff types in order to see the variation of Reference Signal Received Power (RSRP). The simulation results show that the value of distance should be adaptive to the velocity and handoff types of UE in order to reduce the unnecessary handover and hence improved the handoff performance in LTE heterogeneous network.References
