The femtocell networks, which is a small cellular base station in home and small business environment, is an attractive solution for operators to improve indoor coverage and network capability. In addition, relaying is one of the proposed technique for future releases of UTRAN Long Term Evolution (LTE) networks which aims to increase the coverage and capability of LTE networks. A LTE network is called as relay enhanced LTE network if the LTE network adopting the relays. A user can handover not only two relays, but also between relays and base stations, and two base stations. It is important to provide a seamlessly handover solution in the relay enhanced LTE network.
