Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems experience degradation in communication quality and excessive power consumption due to radio interference when the number of wireless terminals is smaller than expected, as wireless base stations remain in a constant operating state.
Innovation Solution
A radio communication system that includes a control apparatus to dynamically control the operating state of multiple wireless base stations based on the number or communication traffic of wireless terminals, using a calculation unit to determine an operating state pattern and an acquisition unit to adjust the base station states accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless base stations operate in a constant state regardless of terminal count, then communication coverage is maintained, but power consumption increases and communication quality deteriorates due to radio interference
Solution Approach 1:
The patent implements dynamic control of wireless base station operating states based on real-time terminal counts. The control unit adjusts the operating state (active, standby, or sleep) of each base station according to the current number of terminals, transforming the static constant-state operation into a dynamic adaptive system that responds to changing traffic conditions, thereby reducing power consumption while maintaining communication quality.
Solution Approach 2:
The patent changes the operating state parameters (power consumption level, transmission activity) of wireless base stations based on terminal count thresholds. When terminal count is low, base stations transition to lower-power states; when terminal count is high, they transition to full-power active states. This parameter adjustment resolves the contradiction by adapting power consumption to actual communication需求的.
2Reliability
If wireless base stations operate in a constant state, then operational simplicity is maintained, but radio interference increases causing communication quality degradation
Solution Approach 1:
The system dynamically adjusts the number of active base stations based on terminal count. When few terminals are present, fewer base stations remain active, reducing the number of simultaneous transmissions and thus reducing radio interference. This dynamic adjustment maintains communication quality by ensuring sufficient coverage while minimizing harmful interference effects.
Solution Approach 2:
The patent extracts or removes unnecessary base stations from the active operating state when terminal count is low. By taking out excess base stations from service (transitioning them to standby or sleep modes), the system eliminates the source of unnecessary radio interference while maintaining adequate coverage through the remaining active base stations.
3Productivity
If the number of wireless base stations is increased to accommodate maximum terminals, then communication capacity is sufficient, but power consumption becomes excessive when fewer terminals are present
Solution Approach 1:
The patent implements dynamic resource allocation where the number of active base stations adjusts according to terminal count. When terminal count approaches maximum capacity, more base stations are activated to provide sufficient communication capacity. When terminal count is low, fewer base stations remain active, reducing power consumption. This dynamic scaling resolves the contradiction between maintaining adequate capacity and minimizing energy waste.
Solution Approach 2:
The system employs partial action by activating only the necessary number of base stations required to serve the current terminal count, rather than keeping all base stations in full operation. This partial activation provides sufficient communication capacity for the actual number of terminals while avoiding the excessive power consumption that would result from operating all base stations at full capacity.
