METHOD AND APPARATUS FOR AUTHENTICATION OF INTEGRATED ACCESS AND BACKHAUL (IAB) NODE IN WIRELESS NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18339118 titled 'METHOD AND APPARATUS FOR AUTHENTICATION OF INTEGRATED ACCESS AND BACKHAUL (IAB) NODE IN WIRELESS NETWORK

Simplified Explanation

This patent application describes a method for authenticating an IAB node in a wireless network. Here are the key points:

  • The method involves obtaining authorization information for the IAB node from the network's Access and Mobility Management Function (AMF) or Mobility Management Entity (MME).
  • The authorization information is used to determine if the IAB node is authorized to access the network.
  • A unique identity or parameter is allocated to the IAB node during various phases of network setup, such as IAB-Mobile Termination (MT) setup, Backhaul Radio Link Control (RLC) channel establishment, and Routing update.
  • The unique identity or parameter is stored in the user equipment (UE) context, which helps identify the UE-context during IAB-Distributed Unit (DU) part setup for authorization check and authentication.


Original Abstract Submitted

Accordingly, the embodiments herein provide a method for authentication of an IAB node by an IAB-donor node in a wireless network. The method includes obtaining an IAB authorization information of the IAB node from one of an Access and Mobility Management Function (AMF) and a Mobility Management Entity (MME) of the wireless network, determining whether the IAB authorization information of the IAB node indicates the IAB node is authorized, and allocating a unique identity/parameter to the IAB node during an IAB- Mobile Termination (MT) setup and/or Backhaul Radio Link Control (RLC) channel establishment and/or Routing update phase. Further, the method includes storing the unique identity/parameter in a user equipment (UE) - context, which is used to identify the UE-context during an IAB- Distributed Unit (DU) part setup for authorization check and/or authentication.
