Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network initiates session establishment procedures, then service continuity and mobility are improved, but device complexity and control overhead increase
Solution Approach 1:
The patent introduces a session management function in the network that acts as an intermediary to coordinate session establishment and continuity. This function manages session contexts and coordinates between access networks, reducing the complexity burden on individual network elements while maintaining reliable service continuity through centralized session control.
2Adaptability or versatility
If session management is optimized for various terminals, then adaptability and service quality improve, but system complexity increases
Solution Approach 1:
The patent implements a universal session management framework that can handle multiple terminal types and access networks through a common interface and procedure set. The session management function is designed to be multi-functional, supporting different terminal capabilities and network configurations without requiring separate management systems, thus improving adaptability while controlling system complexity.
3Reliability
If communication paths are dynamically established and maintained, then service continuity is improved, but use of energy and network resources increases
Solution Approach 1:
The patent implements dynamic session management where communication paths are established and maintained based on actual service needs and terminal mobility states. The system dynamically adjusts session contexts and communication routes according to changing conditions, ensuring continuous connectivity while optimizing network resource usage by avoiding unnecessary path maintenance in stable conditions.
