Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map information is used to select a base station, then selection can be made based on historical data, but the map information does not always match the current bandwidth state leading to suboptimal selection
Solution Approach 1:
The patent applies dynamics by transitioning from static map information to dynamic bandwidth state information. The communication control apparatus continuously acquires and updates bandwidth state information from multiple terminal apparatuses in real-time, allowing the selected base station to reflect current network conditions rather than historical averages. This dynamic update mechanism ensures the selection adapts to changing traffic loads and bandwidth availability.
Solution Approach 2:
The patent implements feedback by having terminal apparatuses report their measured bandwidth state information back to the communication control apparatus. This feedback loop enables the system to continuously monitor actual communication qualities and adjust base station selections accordingly. The communication control apparatus uses this feedback to determine optimal base stations, ensuring selections are based on current rather than outdated information.
2Ease of operation
If terminal apparatus randomly selects an access point, then selection is simple, but connection establishment becomes difficult due to traffic congestion or desired transmission speed cannot be achieved
Solution Approach 1:
The patent introduces a communication control apparatus as an intermediary between terminal apparatuses and base stations. This mediator collects bandwidth state information from multiple terminals, processes the data to determine optimal base station selections, and provides recommendations to terminals. This intermediary approach maintains simplicity for end users while significantly improving connection reliability through informed selection based on aggregated network conditions.
Solution Approach 2:
The patent applies preliminary action by having the communication control apparatus pre-determine optimal base station selections before terminals attempt connections. By analyzing bandwidth state information in advance and identifying suitable base stations, the system prepares selection recommendations that terminals can follow, avoiding random selection and its associated connection failures due to congestion or insufficient bandwidth.
3Measurement precision
If communication quality information is collected from multiple terminals, then more accurate data is obtained, but the amount of information to be processed increases
Solution Approach 1:
The patent applies merging by consolidating communication quality information from multiple terminal apparatuses into a unified dataset processed by the communication control apparatus. Instead of each terminal independently analyzing data from all others, the system combines measurements into aggregate bandwidth state information that captures overall network conditions. This merging maintains measurement precision through multiple data points while simplifying processing by creating a consolidated view of network status.

AI summary
For selection of a wireless access point, a terminal apparatus is configured to include a transmitter transmitting terminal information to a communication control apparatus, a receiver receiving access point candidate information from the communication control apparatus, a bandwidth estimator estimating current bandwidth associated with each of the candidate wireless access points included in the access point candidate information, and an access point selector selecting at least one wireless access point for communication from the candidate wireless access points included in the access point candidate information. Terminal information includes information on a communication location where the terminal apparatus communicates with the communication control apparatus and the access point candidate information includes information on candidate wireless access points for the communication location and past bandwidth information acquired associated with each of the candidate wireless access points. The wireless access point is selected based on past bandwidth information and estimated current bandwidth.
