Handover Adaptations for Load Balancing Scheme in Macrocell/Femtocell LTE Network

Azita Laily Yusof, Norsuzila Ya’acob, and Mohd Tarmizi Ali
Abstract—In the purpose of offering extensively higher data rates, higher systems throughput and lower latency, the femtocell systems in 3GPP LTE system has premeditate. In a large number of femtocells, there are too many prehandover and unnecessary handover processes frequently among femtocells may occur. Also, call failure due to handover may increase when the mobile moves from one serving cell to another cell. High number of switching load will occur due to the ping-pong effect. Handover procedures for existing networks are needed to support the macrocell/femtocell integrated network. This paper proposes a modified handover procedure between macrocell and femtocell network. A handover algorithm is proposed based on Received Signal Strength (RSS) and speed of the UE to improve the handovers between the macrocell and femtocell in LTE network. The result shows that the unnecessary handover and handover failure can be optimized using modified handover in this macrocell and femtocell integrated network. Thus, the deployment of femtocell can increase the handover performance as well as offloading the macrocell traffic.

Index Terms—Handover, macrocell, femtocell, receive signal strength, velocity, dropcall
