Authentication Interworking for Foreign Communication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices that are foreign to a core network cannot directly access or communicate with that network, limiting their ability to utilize services such as call waiting, caller identification, and mobility management.
Innovation Solution
A system that uses authentication information from a native device to authenticate foreign communication devices with the core network, enabling access to services through communication nodes that translate and manage authentication protocols, allowing foreign devices to access services even if they are not natively compatible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If authentication information from a native device is used to authenticate foreign communication devices, then foreign devices can access core network services, but the system complexity increases due to protocol translation and authentication interworking mechanisms
Solution Approach 1:
The patent introduces an authentication server as an intermediary component that mediates between foreign communication devices and the core network. This server receives authentication requests from foreign devices, translates them into native authentication protocols, communicates with the home network's authentication system, and returns results to the foreign device. This intermediary approach enables service access for foreign devices while centralizing the complexity management in a dedicated component rather than distributing it throughout the entire system.
2Adaptability or versatility
If authentication protocols are translated and managed by communication nodes, then foreign devices can communicate with the core network, but the processing time and authentication duration increase
Solution Approach 1:
The patent implements preliminary action by pre-establishing authentication credentials and translating authentication parameters before actual service access is needed. Foreign devices perform authentication with the authentication server in advance, obtaining session tokens or cached authentication results that can be quickly reused for subsequent service requests. This preliminary authentication step reduces the time required for actual service access, as the complex protocol translation and verification have already been completed.
