AUTHENTICATION AND AUTHORIZATION FOR USER EQUIPMENT (UE)-TO-NETWORK RELAYING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17998668 titled 'AUTHENTICATION AND AUTHORIZATION FOR USER EQUIPMENT (UE)-TO-NETWORK RELAYING

Simplified Explanation

The abstract describes a patent application for creating a connection between a remote user equipment (UE) and a relay UE in a PCS (Public Cellular System) network. The relay UE forwards the identifier of the remote UE to the network for authentication. The network checks the authorization for using the relay UE and relaying the remote UE. The access and mobility management function (AMF) facilitates communication between the remote UE and the authentication server function (AUSF) for authentication and authorization. This innovation aims to address security concerns related to relaying a remote UE.

• Creation of a connection between a remote UE and a relay UE in a PCS network.
• Relay UE forwards the identifier of the remote UE to the network for authentication.
• Network checks authorization for using the relay UE and relaying the remote UE.
• AMF facilitates communication between the remote UE and AUSF for authentication and authorization.
• Addresses security issues associated with relaying a remote UE.

Original Abstract Submitted

Systems, methods, apparatuses, and computer program products for creation of a PCS connection between the remote user equipment (UE) and the relay UE. The remote UE may provide its identifier (e.g., a subscription concealed identifier (SUCI)) to the relay UE and the relay UE may forward this identifier to the network so that the network can authenticate the remote UE. The network may check the authorization of using the relay UE and/or for relaying the remote UE (e.g., both the remote UE and the relay UE may be checked for a configuration that permits the relaying). For the authentication and authorization, the access and mobility management function (AMF) associated with the relay UE may forward the messages between the remote UE and the authentication server function (AUSF) of the remote UE. In this way, certain embodiments described herein may address certain security issues related to relaying a remote UE.
