==METHOD AND DEVICE FOR AUTHENTICATING NETWORK ACCESS REQUEST THROUGH TERMINAL-TO-TERMINAL CONNECTION IN MOBILE COMMUNICATION SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18282670 titled 'METHOD AND DEVICE FOR AUTHENTICATING NETWORK ACCESS REQUEST THROUGH TERMINAL-TO-TERMINAL CONNECTION IN MOBILE COMMUNICATION SYSTEM

==Simplified Explanation==

The present disclosure describes a method performed by an Access and Mobility Management Function (AMF) in a wireless communication system to support a higher data transmission rate, specifically in a 5G or 6G communication system. The method involves handling relay user equipment (UE) for UE-network relay communication, including authentication and encryption key establishment.

* Key points:
- AMF receives a relay key request message from a relay UE.
- AMF checks if the relay UE is authorized to provide UE-network relay service.
- AMF identifies an Authentication Server Function (AUSF) related to the remote UE.
- AMF transmits an authentication request message to AUSF.
- Upon successful authentication, AMF acquires a ProSe session encryption key between the remote UE and relay UE.
- AMF transmits the ProSe session encryption key to the relay UE.

== Potential Applications ==
- Enhanced security in relay communication systems
- Improved data transmission rates in 5G and 6G networks
- Efficient management of access and mobility functions in wireless communication systems

== Problems Solved ==
- Ensuring authorized relay UE for UE-network relay service
- Establishing secure encryption keys for ProSe sessions
- Streamlining authentication procedures for remote UEs

== Benefits ==
- Enhanced data security and privacy
- Increased efficiency in relay communication
- Better management of access and mobility functions

== Potential Commercial Applications ==
Optimized for SEO: "Wireless Communication System Applications"
- Telecommunications companies
- IoT device manufacturers
- Network infrastructure providers

== Possible Prior Art ==
There may be prior art related to authentication and encryption key establishment in wireless communication systems, particularly in the context of relay communication and ProSe sessions.

=== Unanswered Questions ===

=== How does this method impact network latency in relay communication systems? ===
The method described in the patent application focuses on authentication and encryption key establishment. However, it does not directly address the potential impact on network latency in relay communication systems. Further research or testing may be needed to determine the latency implications of implementing this method.

=== What are the potential scalability challenges of this method in large-scale wireless communication networks? ===
While the method outlined in the patent application is designed to support higher data transmission rates, the scalability of the system in large-scale wireless communication networks is not explicitly discussed. It would be important to investigate how this method performs and scales in networks with a high volume of relay UEs and remote UEs.


==Original Abstract Submitted==

The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an access and mobility management function (AMF) in a wireless communication system according to an embodiment of the present disclosure comprises: receiving, from a relay user equipment (UE) for a UE-network relay communication, a relay key request message including an identifier of a remote UE for the UE-network relay communication; identifying whether the relay UE is authorized to provide a UE-network relay service; identifying an authentication server function (AUSF) related to the remote UE, based on the identifier of the remote UE; transmitting, to the AUSF, an authentication request message including the identifier of the remote UE; in case that an authentication procedure for the remote UE based on the identifier of the remote UE is successfully performed, acquiring a proximity-based services (ProSe) session encryption key established between the remote UE and the relay UE; and transmitting, to the relay UE, the ProSe session encryption key.
