Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication network technologies consume excessive energy and emit unnecessary electromagnetic radiation due to continuous coverage requirements, especially in multi-user environments where connectivity is unpredictable.
Innovation Solution
A method is implemented by a master device that coordinates access points to switch off non-critical fronthaul networks when all stations are absent, determining station mobility and traffic type to optimize network usage, and gradually switch on networks based on changing traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple access points continuously broadcast fronthaul networks to extend coverage, then wireless network coverage is improved, but energy consumption and electromagnetic radiation increase
Solution Approach 1:
The patent implements dynamic control of access points by transitioning them between active and dormant states based on real-time detection of stations in coverage zones. The master device receives presence information from access points and dynamically adjusts network configuration, making the system adaptable rather than static. This resolves the contradiction by allowing full coverage when needed while reducing energy consumption when stations are absent.
Solution Approach 2:
The system changes operational parameters of access points by modifying their transmission states. When no stations are detected in a coverage zone, the master device switches the corresponding access point from active transmission to dormant state, effectively changing the parameter of electromagnetic radiation emission from high to zero. This parameter change maintains coverage capability while reducing energy consumption.
2Area of stationary object
If multiple access points continuously broadcast fronthaul networks to extend coverage, then wireless network coverage is improved, but electromagnetic radiation emission increases
Solution Approach 1:
The system implements periodic monitoring of station presence in coverage zones rather than continuous transmission. The master device receives presence information at intervals and adjusts access point states accordingly. This periodic action reduces electromagnetic radiation emission while maintaining the ability to provide coverage when stations are present, resolving the contradiction between coverage area and harmful radiation emission.
Solution Approach 2:
The patent extracts unnecessary electromagnetic radiation emission by selectively deactivating access points in zones where no stations are present. The master device identifies and removes the harmful effect (radiation) from specific locations while maintaining it in locations where it is needed, thus resolving the contradiction between providing coverage and minimizing harmful emissions.
3Use of energy by stationary object
If fronthaul networks are switched off according to defined time ranges, then energy consumption is reduced, but service quality deteriorates in multiuser environments with unpredictable connectivity
Solution Approach 1:
The system implements feedback control by having access points continuously monitor and report station presence information to the master device. The master device uses this feedback to make intelligent decisions about which access points to activate or deactivate. This feedback mechanism replaces rigid time-range switching with adaptive, real-time control that maintains service quality while reducing energy consumption.
Solution Approach 2:
Access points autonomously monitor their own coverage zones for station presence and report this information to the master device. Each access point essentially serves itself by detecting when it needs to be active (when stations are present) and when it can be dormant (when no stations are present). This self-service capability enables the system to adapt to unpredictable user connectivity patterns while managing energy consumption efficiently.

AI summary
A method for switching off a communication network is provided. The communication network includes a plurality of access points coordinated by a master device, where each access point manages a wireless network known as a fronthaul network, and where a station is able to associate itself with a fronthaul network of the communication network. At least one item of information relating to each associated station is obtained from each access point, and, for each station, it is determined as to whether it is present or absent according to association information. A phase of switching off at least one fronthaul network is initiated when all the stations are determined as being absent from the communication network.
