Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication session shifting is implemented across different private networks, then user flexibility and service quality are improved, but system complexity and identification security requirements increase
Solution Approach 1:
The patent introduces a registration service infrastructure as an intermediary between communication devices from different private networks. This infrastructure includes registration entities that manage device identification and networking entities that handle session routing. The intermediary abstracts the complexity of cross-network communication, allowing seamless session shifting without requiring direct complex interactions between devices from different networks.
Solution Approach 2:
The system segments the communication infrastructure into distinct functional components: registration entities for device identification and authentication, networking entities for session management and routing, and communication devices for actual communication. This segmentation allows each component to be optimized independently and simplifies the overall system architecture by distributing functionality across multiple specialized elements.
2Reliability
If secure identification of communication devices is implemented across heterogeneous networks, then session shifting reliability is improved, but identification and verification time increases
Solution Approach 1:
The patent implements preliminary registration of communication devices with the registration service infrastructure before actual communication sessions occur. During this preliminary phase, devices obtain unique identifiers and establish their network identities. This pre-registration process ensures that when session shifting is needed, the identification and verification can proceed quickly using previously established credentials, rather than performing full authentication from scratch.
Solution Approach 2:
The registration service infrastructure provides feedback mechanisms that allow networking entities to verify device identities and status in real-time during session shifting operations. The system continuously maintains and updates device registration information, enabling rapid verification through feedback loops between registration entities, networking entities, and communication devices, thereby reducing identification time while maintaining reliability.
