Mobile Terminal Internet Sharing via Authentication Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals without direct communication capabilities with a public land mobile network (PLMN) face challenges in accessing the internet, as they require separate wireless modems and data access accounts, leading to inefficiencies and security concerns regarding unauthorized access.
Innovation Solution
A mobile terminal equipped with a wireless modem and network interface provides data paths to other devices, including authentication mechanisms to ensure secure internet access for multiple devices using a single subscription, leveraging standards like WiFi, Bluetooth, and PLMN technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mobile terminals are equipped with separate wireless modems and data access accounts for PLMN internet access, then each terminal can independently access the internet, but the system complexity and cost increase due to requiring multiple subscriptions and accounts
Solution Approach 1:
The first mobile terminal is configured to provide internet access to multiple other mobile terminals through its wireless modem and network interface, making it a universal access point for the group. This single terminal performs the function of multiple modems, allowing terminals without direct PLMN capability to access the internet through it.
Solution Approach 2:
The first mobile terminal acts as an intermediary between the PLMN network and other mobile terminals. It receives and processes authentication information from multiple terminals, validates it against stored permitted authentication codes, and establishes data paths accordingly, mediating access control for the entire group.
2Device complexity
If multiple mobile terminals share a single PLMN connection through one terminal, then the number of subscriptions and accounts is reduced, but security risks increase due to potential unauthorized access
Solution Approach 1:
The first mobile terminal stores a list of permitted authentication codes in its memory before any access attempts occur. These authentication codes are pre-configured and associated with specific mobile terminals, enabling the system to quickly verify authenticity without real-time complex validation processes.
Solution Approach 2:
The system implements authentication feedback by comparing authentication information received from attempting terminals against the stored permitted authentication codes. Based on this comparison, the system provides feedback by either establishing a data path for authenticated terminals or blocking access for unauthenticated ones, creating a closed-loop security mechanism.
3Reliability
If authentication mechanisms are implemented for shared internet access, then security is enhanced by preventing unauthorized access, but the ease of operation decreases due to requiring authentication procedures
Solution Approach 1:
Instead of requiring complex authentication protocols, the system uses simplified authentication codes that can be easily copied or shared among authorized users. These codes serve as lightweight credentials that maintain security while significantly reducing the operational burden compared to traditional authentication mechanisms.
Data Source
AI summary
A mobile terminal may include a wireless modem, a wireless network interface, and an application (such as a browser application). A method of operating the mobile terminal may include providing a first data path between a data network and the application of the mobile terminal through the wireless modem. In addition, a second data path may be provided between the data network and second mobile terminal through the wireless modem and the wireless network interface of the first mobile terminal.
