Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, fixed communication bands between radio base stations and control apparatuses can lead to service interruptions when actual user access exceeds design predictions, resulting in areas where communication is not possible.
Innovation Solution
A mobile communication system that dynamically calculates and assigns communication bands for each transmission line based on positional information from radio terminals, using a core network unit and multiplex transmission apparatus to adjust bands according to the number of users and their distribution, allowing flexible accommodation of changes in communication demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed communication bands are set beforehand by system design, then system stability and simplicity are improved, but adaptability to actual user access patterns deteriorates
Solution Approach 1:
The communication band allocation is changed from a static fixed value to a dynamic value that is recalculated based on actual positional information of radio terminals. The core network unit dynamically adjusts the communication bands for each transmission line according to real-time user distribution, enabling the system to adapt to varying access patterns while maintaining operational stability.
Solution Approach 2:
The communication band parameters are changed from predetermined fixed values to dynamically calculated values based on actual user positional information. This parameter change allows the system to optimize bandwidth allocation according to real-time conditions, resolving the contradiction between system simplicity and adaptability.
2Ease of manufacture
If communication bands are set based on predicted user numbers, then system design simplicity is improved, but service reliability under actual load deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring the positional information of radio terminals and using this information to recalculate and adjust communication band allocations. This feedback mechanism ensures that service reliability is maintained under actual load conditions by dynamically optimizing bandwidth distribution based on real-time user distribution, while the underlying system design remains relatively simple.
3Device complexity
If fixed communication bands are used, then device complexity is reduced, but productivity in handling excess user access deteriorates
Solution Approach 1:
The band allocation system transitions from a static fixed configuration to a dynamic recalculation process that adapts to actual user access patterns. This dynamic approach enables the system to handle excess user access efficiently by allocating communication bands based on real-time positional information, thereby improving productivity without significantly increasing device complexity.
4Adaptability or versatility
If communication bands are dynamically calculated based on positional information, then adaptability to user access patterns is improved, but system complexity increases
Solution Approach 1:
The core network unit performs multiple functions including positional information reception, communication band calculation, and transmission line management within a single integrated system. This multi-functionality approach enables dynamic band allocation to improve adaptability while minimizing the increase in overall system complexity by consolidating control functions.
