METHODS AND SYSTEMS FOR MITIGATING DENIAL OF SERVICE (DOS) ATTACK IN A WIRELESS NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18353752 titled 'METHODS AND SYSTEMS FOR MITIGATING DENIAL OF SERVICE (DOS) ATTACK IN A WIRELESS NETWORK

Simplified Explanation

This patent application is about a method and system for mitigating Denial of Service (DOS) attacks in wireless networks, specifically in the context of pre-5G or 5G communication systems. The innovation involves performing admission control by verifying a User Equipment's (UE's) registration request via a Closed Access Group (CAG) cell without performing a primary authentication. Here are the key points:

  • The patent application focuses on supporting higher data rates in wireless networks beyond the existing 4G communication systems like Long Term Evolution (LTE).
  • The innovation aims to mitigate Denial of Service (DOS) attacks, which are malicious attempts to disrupt the normal functioning of a network.
  • The method involves verifying a UE's registration request through a Closed Access Group (CAG) cell without performing a primary authentication.
  • By verifying the permissions of the UE to access a non-public network (NPN) through the CAG cell based on the UE's Subscription identifier, the system can prevent unauthorized access attempts.
  • The method includes requesting a public land mobile network for accessing the requested NPN through the CAG cell and performing a primary authentication after verifying the permissions.
  • This approach helps in reducing the impact of DOS attacks by adding an additional layer of security and control before performing the primary authentication process.


Original Abstract Submitted

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution. Methods and systems for mitigating Denial of Service (DOS) attacks in wireless networks, by performing admission control by verifying a User Equipment's (UE's) registration request via a Closed Access Group (CAG) cell without performing a primary authentication are provided. Embodiments herein disclose methods and system for verifying permissions of the UE to access a CAG cell based on the UE's Subscription identifier, before performing the primary authentication. The method for mitigating DOS attacks in wireless networks includes requesting a public land mobile network for accessing a non-public network (NPN) through a CAG cell, verifying the permissions of a UE to access the requested NPN through the CAG cell, and performing a primary authentication.
