VoIP Telephone PPPoE Client Module for Toll Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VoIP deployments face challenges in maintaining toll quality due to network congestion and LAN configuration issues, which degrade voice quality, particularly in consumer broadband settings where devices rely on home gateways or PCs to initiate PPPoE sessions.
Innovation Solution
A VoIP communication system featuring a managed network with an access router, media gateway, and broadband remote access server using policy-based routing and dedicated virtual circuits for VoIP traffic, along with a VoIP telephone apparatus equipped with a PPPoE client module, encoder/decoder, and a PPPoE function key to manage sessions effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing broadband access is used as transport channel for VoIP service, then deployment simplicity is improved, but voice quality deteriorates due to network congestion
Solution Approach 1:
The patent segments the broadband connection into separate PPPoE sessions: one dedicated to VoIP traffic and another to data traffic. This segmentation allows VoIP to have guaranteed quality of service while data traffic handles general internet access, resolving the conflict between deployment simplicity and voice quality by creating isolated traffic streams with different quality requirements.
Solution Approach 2:
The patent applies local quality by providing differentiated service quality to different traffic types within the same network infrastructure. VoIP traffic receives prioritized handling with guaranteed bandwidth and lower latency, while data traffic receives standard service, allowing the system to maintain simple broadband deployment while ensuring high voice quality through localized quality adjustments.
2Device complexity
If home gateway or PC initiates PPPoE session for VoIP service, then device complexity is reduced, but voice quality deteriorates due to LAN configuration issues
Solution Approach 1:
The patent implements self-service by enabling the IP phone itself to initiate and manage PPPoE sessions directly, without requiring a home gateway or PC to act as an intermediary. This eliminates LAN configuration complexities and potential failure points while maintaining simple device operation, as the phone autonomously establishes its own connection with guaranteed quality parameters.
3Stability of the object's composition
If static IP assignment is used for VoIP phone, then network stability is improved, but adaptability deteriorates
Solution Approach 1:
The patent applies universality by making the IP phone capable of operating in multiple modes: it can function with static IP assignment for stable, dedicated VoIP service, or with dynamic IP assignment through PPPoE for greater adaptability. The phone universally supports both assignment methods, allowing it to adapt to different network configurations while maintaining stable VoIP performance through protocol-specific quality guarantees.
