Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication between a relay base station and a donor base station using millimeter waves experiences instability due to high propagation loss and dynamic changes in communication quality, leading to frequent path switching and potential communication instability.
Innovation Solution
A communication control apparatus that acquires information about the services to be received by a terminal apparatus and determines an optimal path for data exchange between the terminal apparatus and the donor base station based on this information, utilizing network slicing to manage path switching and ensure stable communication.

Engineering Contradiction Analysis
1Area of stationary object
If wireless communication is used for backhaul line between relay base station and donor base station, then area coverage is improved, but communication stability deteriorates
Solution Approach 1:
The patent segments the communication path into multiple paths (first path through relay base station, second path directly through donor base station) and selectively uses them based on service requirements. This allows the system to maintain area coverage while improving communication stability by switching between segmented paths when needed.
Solution Approach 2:
The patent dynamically selects and switches between different communication paths based on real-time communication quality assessment and service requirements. The determination section dynamically adjusts the data transmission path, transitioning from a fixed relay-based path to a flexible multi-path approach that adapts to changing wireless conditions.
2Productivity
If millimeter wave is utilized for backhaul line, then backhaul capacity is improved, but path switching frequency increases
Solution Approach 1:
The patent performs preliminary assessment of communication quality and service requirements before determining the data transmission path. By evaluating factors such as propagation loss and dynamic changes in advance, the system can pre-determine optimal paths and reduce reactive path switching, thereby maintaining high backhaul capacity while minimizing path switching frequency.
Solution Approach 2:
The patent incorporates feedback mechanisms where the determination section continuously monitors communication quality and adjusts path selection accordingly. This feedback loop allows the system to maintain stable connections by detecting degradation trends early and switching paths proactively, reducing unnecessary path switching while preserving millimeter wave backhaul capacity.
3Adaptability or versatility
If frequent path switching occurs, then communication quality adapts to changes, but signaling load increases
Solution Approach 1:
The patent applies different quality assessment and path selection criteria to different services based on their specific requirements. Instead of uniformly switching paths for all traffic, the system evaluates local quality metrics for each service type (e.g., voice, data, video) and makes targeted path selection decisions, thereby reducing overall signaling load while maintaining adaptability for critical services.
