Modem Auto-Configuration via Network Property Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modems require manual reconfiguration when network properties change, causing inconvenience to users due to different service provider network configurations for VoIP and Internet access services.
Innovation Solution
A modem with integrated DHCP, PPPoE, network monitor, and HTTP modules that automatically detect and configure network properties upon power-on, establishing connections and retrieving necessary parameters to provide VoIP and Internet access services based on detected network support for DHCP and PPPoE, reducing the need for manual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the modem is preset with different network configurations for different service providers, then the modem can support multiple network properties (DHCP, PPPoE), but the device complexity increases and manual reconfiguration is still required when network properties change
Solution Approach 1:
The modem automatically detects network properties (DHCP or PPPoE) and configures itself without user intervention. The system monitors network responses and self-adjusts configuration parameters, eliminating the need for manual reconfiguration when switching between service providers
Solution Approach 2:
The modem configuration is made dynamic rather than static. The system continuously monitors network properties and automatically adjusts configuration parameters in real-time, allowing the modem to adapt to changing network environments without requiring manual intervention or complex preset configurations
2Reliability
If the modem requires manual reconfiguration when network properties change, then the configuration can be precise for each service provider, but the ease of operation deteriorates due to user inconvenience
Solution Approach 1:
The modem performs self-configuration by automatically detecting network properties and adjusting parameters accordingly. The system sends test packets to detect DHCP or PPPoE networks and self-modifies configuration without requiring user input, maintaining configuration accuracy while eliminating manual operation
Solution Approach 2:
The system implements a feedback mechanism where the modem monitors network responses and uses this information to automatically adjust configuration. The detection of network properties through packet exchange provides feedback that triggers automatic reconfiguration, ensuring accurate configuration for each service provider while maintaining user convenience
3Ease of operation
If the modem automatically detects and configures network properties, then the ease of operation improves by eliminating manual reconfiguration, but the device complexity increases due to additional monitoring and detection functions
Solution Approach 1:
The modem integrates multiple functions into unified modules that handle both detection and configuration. The network monitor module and DHCP/PPPoE modules serve multiple purposes: they detect network properties, establish connections, and configure parameters, reducing overall system complexity despite added automation capabilities
Solution Approach 2:
The patent combines detection, connection establishment, and configuration functions into integrated modules. The network monitor module works closely with DHCP and PPPoE modules to perform detection and configuration in a unified process, reducing the complexity that would arise from separate independent systems
Data Source
AI summary
A modem includes a dynamic host configuration protocol (DHCP) module, a point-to-point protocol over Ethernet (PPPoE) module, and a network monitor module. The DHCP module automatically establishes a DHCP connection over a communication network, and generates a first notification signal after the DHCP connection is established. The PPPoE module automatically establishes a PPPoE connection over the communication network and automatically configures parameters of an Internet access service over the communication network and generates a second notification signal after the PPPoE connection is established. The network monitor module determines current network properties of the communication network upon receipt of the first notification signal and/or the second notification signal, and selectively configures parameters of the Internet access service and a voice over Internet protocol (VoIP) service.
