APPARATUS AND METHOD FOR PROVIDING SECURITY IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17795107 titled 'APPARATUS AND METHOD FOR PROVIDING SECURITY IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The patent application describes an apparatus and method for enhancing security in a wireless communication system. Here is a simplified explanation of the abstract:

  • The user equipment (UE) sends a registration request message to an access and mobility management function (AMF).
  • If the AMF rejects the registration, the UE then sends an attach request to a mobility management entity (MME).
  • The MME responds with an attach accept to the UE.
  • If the AMF and the UE already have a security context, the AMF can send a security-protected registration reject message to the UE.
  • In this case, the AMF can redirect the UE's registration request to the MME.
  • If either the AMF or the UE does not have security context information, the attach request includes security verification information.

Potential applications of this technology:

  • Wireless communication systems that require enhanced security measures.
  • Mobile networks where user equipment needs to register and attach securely.
  • Systems that need to redirect registration requests between different management entities.

Problems solved by this technology:

  • Ensures secure communication between user equipment and management entities.
  • Provides a mechanism for redirecting registration requests when necessary.
  • Allows for secure registration and attachment in wireless communication systems.

Benefits of this technology:

  • Enhanced security in wireless communication systems.
  • Improved reliability and integrity of registration and attachment processes.
  • Flexibility to handle different security context scenarios.


Original Abstract Submitted

Provided are an apparatus and method for providing security in a wireless communication system. A user equipment (UE) may transmit a registration request message to an access and mobility management function (AMF), in response to reception of a registration reject message from the AMF, transmit an attach request to a mobility management entity (MME), and receive an attach accept from the MME, wherein, when the AMF and the UE have a security context, a security-protected registration reject message may be transmitted by the AMF to the UE, a registration request from the UE may be redirected from the AMF to the MME, and when at least one of the AMF and the UE does not have security context information, the attach request may include security verification information.
