Wireless Terminal Call Management in Jammed Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio communication networks face challenges in efficiently managing network load during peak usage periods and locations, such as stations or shrines during holidays or rainy days, where call attempts exceed communication capacity, leading to difficulties in voice calling and increased network load.
Innovation Solution
A radio communication control device that detects cell jamming, confirms user intentions regarding additional charges for calls made in jammed states, and adjusts charge settings to manage call traffic by blocking or allowing calls based on user consent, thereby reducing the number of call attempts and network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system allows all call-up operations during peak periods, then user accessibility is maintained, but network load increases and communication capacity is exceeded
Solution Approach 1:
The system performs preliminary detection of cell jamming states before allowing call-up operations. The base station detects whether a cell is in a jammed state and proactively notifies the terminal of additional charges before the call is established, preventing excessive network load during peak periods
Solution Approach 2:
The system implements feedback mechanisms where the base station continuously monitors cell conditions, detects jamming states, and provides real-time notifications to terminals about additional charges. This feedback loop enables dynamic adjustment of call-up operations based on current network conditions
2Quantity of substance
If the system blocks call-up operations in jammed cells, then network load is reduced, but user accessibility deteriorates
Solution Approach 1:
The system dynamically adjusts call-up blocking decisions based on real-time cell conditions and user responses. Rather than static blocking, the system notifies users of additional charges and allows them to decide whether to proceed, creating a dynamic balance between load reduction and accessibility
Solution Approach 2:
The system changes the charge parameter dynamically based on cell jamming detection. When a cell is detected as jammed, an additional charge is imposed on call-up operations, creating a price-based mechanism to regulate network usage and reduce load during peak periods
3Productivity
If additional charges are imposed on call-up operations in jammed cells, then call traffic is reduced, but user convenience decreases
Solution Approach 1:
The system applies preliminary anti-action by notifying users of additional charges before they initiate call-up operations in jammed cells. This advance warning allows users to make informed decisions and potentially avoid calls during high-congestion periods, thereby reducing overall call traffic
Solution Approach 2:
The base station acts as an intermediary that mediates between user call-up requests and network conditions. It detects jamming states, determines additional charges, and communicates this information to terminals, serving as a mediator that balances user convenience with network load management

AI summary
A radio communication control device accepts a call-up from a radio communication terminal and includes a unit configured to detect the degree of jamming in a cell, a unit configured to confirm the intention of a user of a terminal concerned as to whether the call-up is continued regardless of addition of an extra to the user's telephone call charge when the call-up has been made from a radio communication terminal in the cell concerned in a specific jammed state, a unit configured to block the call-up concerned in accordance with the confirmed intention of the user of the terminal concerned and a unit configured to change charge setting so as to add an extra to the user's telephone call charge when the call-up has not been blocked in the specific jammed state.
