Advanced Handover Techniques in 5G LTE-A Networks

2021 International Journal of Emerging Trends in Engineering Research  
In High-speed and seamless access is the goal of next-generation mobile communication systems, especially for VoIP and multimedia services. The supported mobile speeds are expected to reach 500 km/h in the Fifth Generation Networks (5G), lead to the handover will take place continuously as the mobile user moves through the cells. Therefore, efficient radio resource management, including the handover, load balancing technologies is vital problems. In this work, we perform a comprehensive survey

In the LTE-Advanced system, Fractional Soft Handover (FSHO) with 5 CCs improves latency and better handover quantity when not using CA. Currently, the proposed handover techniques have many advantages but have not yet resolved important issues in the handover process. Therefore, new handover techniques are required to support a fast and seamless handover process in the LTE-Advanced system. As a result, an advanced transfer technique proposed by combining FSHO, SSHO techniques can reduce latency, enhance efficiency and reliability, especially in the border areas between the cells.
