Abstract

Wireless communication is an important ways for mobile services. The emergence of third generation mobile services and smart phones has changed the way people live their lives by using the services they need for life such as phone calls, messages, and Internet search as one device. The 4th generation mobile communication currently in use is providing users with various services using wide bandwidth and speed. But the 3th generation mobile network has a closed structure that makes it difficult to attack. However, the 4th generation mobile network operates by identifying IP addresses in an open environment. These changes can give attackers a lot of attack opportunities. In this paper, we focus on the changes of 4th generation mobile communication and its weaknesses, and examine the direction of 5th generation mobile communication.
