Mobile Terminal PPPoE Dialing Module and Security Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals lack a built-in Point-to-Point Protocol over Ethernet (PPPoE) dialing function, making it inconvenient to connect to the internet using PPPoE dialup, especially with new-generation home gateways that require separate authentication for each terminal accessing the internet.
Innovation Solution
A mobile terminal with a built-in PPPoE dialing function, comprising a PPPoE dialing module and a security management module, which receives account information, authenticates it, and triggers PPPoE dialing connections, ensuring secure internet access through a mechanism involving an agent process with root permission to manage network operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common router with PPPoE dialing function is used, then internet connection is convenient, but each terminal cannot perform separate authentication
Solution Approach 1:
The patent merges the PPPoE dialing function into the mobile terminal itself, combining the authentication capability and connection function into a single integrated system. This allows the terminal to perform both authentication and internet connection independently, resolving the contradiction between connection convenience and authentication versatility.
Solution Approach 2:
The mobile terminal is designed with multi-functionality, serving both as an authentication device and as an internet connection device. The terminal can independently perform PPPoE authentication and establish network connections, making it universally applicable for both home and public WiFi scenarios without requiring separate routing equipment.
2Adaptability or versatility
If an ADSL access box with bridging technology is used, then new-generation home gateway service is provided, but separate authentication is required on each terminal
Solution Approach 1:
The mobile terminal performs self-service by independently completing PPPoE authentication and network connection establishment without requiring external authentication devices. The terminal autonomously manages account information, performs authentication sequences, and establishes connections, eliminating the need for separate authentication operations on each terminal.
Solution Approach 2:
The authentication and connection process is segmented into distinct functional modules within the terminal: account information management module, authentication module, and connection establishment module. This segmentation allows each module to handle specific tasks independently, simplifying the overall operation while maintaining versatility.
3Device complexity
If existing mobile terminal without PPPoE dialing function is used, then device simplicity is maintained, but PPPoE dialup connection cannot be established
Solution Approach 1:
The PPPoE dialing function is nested within the mobile terminal's existing architecture, integrating authentication and connection modules into the terminal's operating system framework. This nested structure allows the terminal to maintain its original simplicity while embedding advanced PPPoE capabilities, avoiding the need for separate external devices.
4Adaptability or versatility
If PPPoE dialing function is added to mobile terminal, then internet connection capability is improved, but system security may be compromised
Solution Approach 1:
An agent process with root permission is introduced as an intermediary between the PPPoE dialing function and the terminal's core system. This intermediary manages network operations and authentication processes, isolating potential security risks from the core system while maintaining full functionality. The agent acts as a controlled interface that protects system integrity.
Solution Approach 2:
Root permissions and special authentication capabilities are localized to specific modules and processes within the terminal rather than being system-wide. The PPPoE dialing function and agent process have targeted access rights only where needed, minimizing security exposure while maintaining connection capability. This localized approach ensures that even if the dialing function is compromised, the core system remains protected.

AI summary
Disclosed is a mobile terminal with a built-in PPPoE dialing function, comprising a PPPoE dialing module and a security management module. The PPPoE dialing module is configured to receive account information input by a user, send the account information to the security management module for identity authentication, receive a PPPoE dialing instruction sent by the security management module, and trigger and complete a PPPoE dialing connection. The security management module is configured to receive account information sent by the PPPoE dialing module, perform identity authentication, and send a PPPoE instruction to the PPPoE dialing module after the authentication is successful, and is further configured to feed back state information during a PPPoE dialing process to the PPPoE dialing module. Also disclosed is a dialing method of a mobile terminal with a built-in PPPoE dialing function. The present invention can satisfY the requirement for dialing up in a PPPoE manner of a mobile terminal user.
