Problem
Current network access technologies require complex customer involvement in configuring residential gateways, leading to potential mis-configurations, service disruptions, and increased support needs, especially when transitioning between wireline and wireless access methods.
Innovation Solution
A unified service architecture that integrates a residential gateway with both wireline and wireless interfaces, utilizing a SIM card for authentication and an Evolved Packet Core (EPC) network to manage access and configuration, allowing seamless switching between interfaces and reducing customer involvement in configuration processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customers manually configure residential gateways with wireline access, then network access is established, but configuration errors occur and service reliability decreases
Solution Approach 1:
The system performs self-configuration by automatically detecting wireline access availability and establishing connections without customer intervention. The residential gateway autonomously manages credential provisioning and network parameter configuration, eliminating manual setup errors while maintaining ease of deployment.
Solution Approach 2:
Authentication credentials and network configuration parameters are pre-provisioned in the system before customer arrival. When the customer connects the gateway, the configuration is automatically applied without requiring manual input, thus ensuring reliability while maintaining operational simplicity.
2Adaptability or versatility
If residential gateways use wireline access only, then stable network connection is achieved, but adaptability to different access scenarios is reduced
Solution Approach 1:
The residential gateway is designed with multi-functionality to support both wireline and wireless access methods through a unified authentication mechanism. The same gateway hardware and SIM card-based authentication can handle multiple access technologies, providing adaptability without proportionally increasing configuration complexity.
Solution Approach 2:
The system dynamically selects between wireline and wireless access methods based on availability and service requirements. The gateway automatically transitions between access modes without requiring complex manual reconfiguration, adapting to changing network conditions while maintaining manageable device complexity.
3Ease of operation
If customers manage authentication credentials manually, then access control is maintained, but time consumption and operational difficulty increase
Solution Approach 1:
The gateway automatically manages authentication credentials through self-service mechanisms. The SIM card-based authentication system autonomously handles credential verification, session management, and re-authentication without requiring customer intervention, thus simplifying operation and reducing time consumption.
Solution Approach 2:
The SIM card serves as an intermediary that simplifies authentication by replacing complex manual credential management with a standardized, automated identification system. The network infrastructure mediates the authentication process, handling verification and credential provisioning without requiring customers to manually manage passwords or security tokens.
4Reliability
If wireless access interface is added to residential gateway, then adaptability and failover capability improve, but device complexity increases
Solution Approach 1:
The residential gateway incorporates both wireline and wireless access interfaces with a unified authentication and control architecture. This multi-functional design enables automatic failover between access methods, improving reliability while managing device complexity through shared authentication mechanisms and centralized control logic.
Solution Approach 2:
The system prepares failover capability in advance by pre-configuring both wireline and wireless interfaces with authentication credentials. When primary access fails, the system can immediately switch to the backup interface without requiring complex real-time decision-making or reconfiguration, thus improving reliability while keeping the switching logic relatively simple.
