Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current routing assistance information is used from terminal to network, then network can receive routing information, but routing accuracy is insufficient leading to AMF routing errors and resource overhead
Solution Approach 1:
The terminal device performs preliminary action by providing function information indication in advance (in RRC setup or registration procedures) before the actual routing decision is needed. This allows the network to prepare appropriate routing information proactively, improving routing accuracy while reducing subsequent routing failures and resource overhead.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal provides function information indication to the network, and the network responds with routing information. This iterative feedback loop ensures routing accuracy is improved continuously, allowing the network to adjust routing decisions based on terminal's actual function requirements, thereby reducing resource overhead from routing errors.
2Productivity
If current routing assistance information is used, then network can process routing requests, but service waiting time becomes too long affecting system performance
Solution Approach 1:
The terminal provides function information indication during initial RRC setup or registration procedures, before service activation is needed. This preliminary provision of routing information allows the network to pre-configure appropriate routing paths, significantly reducing service waiting time when actual data transmission begins, thereby improving system performance.
Solution Approach 2:
The patent ensures continuity of useful action by establishing routing information provision as an ongoing process during terminal initialization and registration. The network continuously maintains and updates routing information based on terminal's function requirements, ensuring smooth and efficient service activation without interruptions or long waiting periods, thus improving both productivity and reliability.
