Abstract:
The amount of data required by various applications continues to increase due to improved high function terminals. We expect that using Long Term Evolution (LTE) networks will also grow in the future. Networks might become very crowded depending on the places and the times at which people congregate. To reduce network congestion, carriers are offloading LTE network traffic to WiFi systems. Because the frequency resources of LTE networks are limited, movements that utilize them will increase in the future. When a mobile terminal communicates using a communication system with a narrow coverage area, such as WiFi, the frequency of switching the Access Point (AP) increases compared to using Cellular Networks. Since AP switching frequently occurs, network connections must be made more quickly. Here, the communication disconnection time denotes an efficient switching. Therefore, in this research, we select an AP for connections based on position and speed, both of which are unique to mobile terminals, and utilize the concept of a Software Defined Network (SDN). We propose a method that enables efficient network connections by executing an AP procedure that is connected before the communication is disconnected.
