Communication Terminal Relay Path Switching for Authentication Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, malfunctions can prevent new terminals from authenticating and performing data communications when a base station cannot communicate with an authentication device, as existing technologies do not address this specific scenario effectively.
Innovation Solution
A communication terminal and system that determine the normal operation of external communication network relay devices, select substitute terminals, and instruct internal wireless communication network relay devices and bypassing relay devices to perform authentication and data relaying processes, allowing new terminals to authenticate and communicate even when the authentication device is unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses a centralized authentication device for terminal authentication, then authentication security and control are improved, but system reliability deteriorates when the authentication device malfunctions
Solution Approach 1:
The patent introduces a relay device as an intermediary between terminals and the authentication device. This relay device forwards authentication requests and responses, enabling terminals to authenticate even when direct communication with the authentication device is interrupted. The relay device acts as a mediator that maintains authentication functionality during network disruptions.
Solution Approach 2:
The patent establishes relay devices in advance as backup communication paths. When the authentication device becomes unavailable, these pre-positioned relay devices can immediately step in to forward authentication traffic, avoiding the need for real-time path reconstruction and ensuring continuous authentication service.
2Reliability
If the system maintains direct communication paths between base stations and authentication devices, then communication efficiency is improved, but communication reliability deteriorates when external network interruptions occur
Solution Approach 1:
The patent segments the authentication communication path into multiple independent segments: terminal to relay device, relay device to base station, and base station to authentication device. This segmentation allows individual segments to fail without collapsing the entire authentication process, as relay devices can maintain local forwarding capabilities even when external network paths are interrupted.
3Speed
If the system allows terminals to bypass the authentication device for direct external network access, then communication speed is improved, but security control deteriorates
Solution Approach 1:
The patent performs authentication in advance through the relay device before establishing direct data transmission paths. Terminals obtain authentication tokens and network access permissions beforehand, allowing them to bypass the authentication device during actual data transmission while maintaining security control. The relay device validates tokens and enforces access policies, ensuring security without hindering transmission speed.

AI summary
A communication terminal including: a first normal operation determination unit determines whether an external communication network relay device is operating normally; a terminal selection unit selects a substitute communication terminal for executing a first substitute process for the external communication network relay device; a first instruction unit, when the own communication terminal is selected, instructs an internal wireless communication network relay device to perform processes of relaying a connection information allocation request and a response to the allocation request between the requesting communication terminal and the own communication terminal, relaying data relating to authentication between the own communication terminal and the authentication device, and relaying data for the external communication network to the external communication network; and a second instruction unit instructs a bypassing relay device to perform a process for relaying the data relating to authentication between the internal wireless communication network relay device and the authentication device.
