Innovation Solution
The system enhances communication stability by transmitting specialized broadcast information to wireless relay devices, allowing them to perform location registration and camp on wireless base stations, while maintaining compatibility with existing mechanisms and ensuring safety of traffic communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless relay devices use existing communication mechanisms to connect with base stations, then device compatibility is maintained, but communication stability deteriorates when direct communication is not possible
Solution Approach 1:
The patent introduces a wireless relay device as an intermediary between mobile bodies and wireless base stations. The relay device receives broadcast information from base stations and retransmits it to mobile bodies, enabling indirect communication when direct communication is not possible. This mediator approach resolves the contradiction by maintaining compatibility with existing base station broadcast mechanisms while enabling stable communication through the relay path.
2Reliability
If wireless relay devices perform location registration without specialized broadcast information, then system complexity is reduced, but communication safety deteriorates
Solution Approach 1:
The patent segments broadcast information into different types: general broadcast information for terminal devices and specialized broadcast information for wireless relay devices. The base station transmits both types, and the relay device selectively processes the specialized information for location registration. This segmentation enables safe traffic communication through dedicated registration mechanisms while keeping the overall system manageable by maintaining separate information streams.
3Productivity
If wireless relay devices are integrated into existing communication systems, then system simplicity is maintained, but processing effectiveness for relay devices deteriorates
Solution Approach 1:
The patent applies local quality by providing specialized broadcast information specifically tailored for wireless relay devices' location registration needs, while terminal devices continue to use general broadcast information. The base station transmits both types of information with different characteristics, and each device type processes only the relevant information. This local quality approach improves processing effectiveness for relay devices without requiring a complete system restructuring.
