Residential Gateway Dual Authentication for Automatic Broadband Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing residential gateway authentication methods require user interaction for secure access to broadband services, which is undesirable in scenarios where user interaction is impractical or impossible.
Innovation Solution
A method for remote authentication of residential gateways using dual authentication mechanisms, involving a first authentication with the broadband network and a second authentication with the mobile network, allowing automatic service activation without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-factor authentication is implemented to strengthen security, then authentication security is improved, but user interaction complexity increases
Solution Approach 1:
The residential gateway performs authentication operations autonomously without requiring user intervention. The gateway automatically executes the first authentication with the broadband network and the second authentication with the mobile network, enabling self-service authentication that maintains security while eliminating user interaction complexity
Solution Approach 2:
The authentication process is performed in advance before service activation. The gateway completes both authentication steps with the broadband network and mobile network beforehand, so that when service activation is needed, the authentication is already completed, eliminating the need for user interaction at the time of service access
2Ease of operation
If automatic authentication is implemented without user interaction, then ease of operation is improved, but authentication security may be compromised
Solution Approach 1:
The authentication process is divided into two distinct authentication steps: a first authentication with the broadband network and a second authentication with the mobile network. This segmentation ensures that multiple security checks are performed independently, maintaining strong authentication security while enabling automatic operation without user interaction
Solution Approach 2:
The residential gateway acts as an intermediary that automatically performs the authentication operations between the broadband network and mobile network. The gateway mediates the authentication process, executing the necessary security checks without requiring direct user involvement, thus maintaining both security and ease of operation
3Reliability
If dual authentication mechanism is implemented, then authentication security is improved, but device complexity increases
Solution Approach 1:
The residential gateway is designed with multi-functionality to handle both the first authentication with the broadband network and the second authentication with the mobile network. By making the gateway universal and capable of performing multiple authentication functions, the patent avoids increasing overall system complexity while still implementing dual authentication for enhanced security

AI summary
A residential gateway includes a modem for connecting to a mobile network through which a broadband network is accessible, and a broadband controller for connecting to the broadband network. The residential gateway activates a service when two authentication steps are successfully completed: first authentication (503) and second authentication (506), which are: authentication of the residential gateway to the broadband network by the broadband controller; and authentication of the residential gateway to the mobile network by the modem via a mobile network user plan.
