Dynamic Access Point Activation for Wireless Network Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular networks face inefficiencies in power consumption and radio resource utilization due to the constant operation of wireless access points, even when they are not in use, leading to unnecessary power consumption and wireless signal interference.
Innovation Solution
Implement a dynamic activation and deactivation system for wireless access points, where access points are activated when a user device is within communication range and deactivated when unused, using a network device selector to manage the handoff between base stations and access points based on location and session information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access points operate continuously to ensure availability, then user device connectivity is maintained, but power consumption and radio resource usage increase unnecessarily
Solution Approach 1:
The access point transitions from a static always-on state to a dynamic state that changes based on user presence. The system monitors user device locations and actively adjusts access point operational status, transitioning between active and inactive states to optimize the balance between availability and energy consumption.
Solution Approach 2:
The system changes the operational parameter of access points from a fixed 'on' state to a variable state based on utilization metrics. When no user devices are detected within communication range, the access point parameter is changed to 'inactive' or 'off', reducing power consumption while maintaining reliability through conditional activation.
2Reliability
If access points remain active continuously, then user devices can connect anytime, but wireless signal interference increases
Solution Approach 1:
The access point's operational state dynamically responds to real-time conditions. When the system detects that no user devices are present within the access point's communication range, it transitions to an inactive state, thereby reducing wireless signal interference while maintaining connection availability when users are present.
3Use of energy by moving object
If access points are activated only when needed, then power consumption decreases, but response time for activating new access points increases
Solution Approach 1:
The system performs preliminary actions by maintaining access points in an 'active' or 'ready' state when user devices are detected nearby, even if no specific connection request has occurred yet. This proactive approach ensures that when a user device needs connectivity, the access point is already activated and ready to serve the user, minimizing activation delay.
Solution Approach 2:
The system continuously monitors the location of user devices and uses this feedback information to determine when to activate or deactivate access points. This real-time feedback mechanism ensures that access points are activated in anticipation of user needs based on detected user presence, balancing power savings with minimal activation time.

AI summary
A network selection device may determine that a communication between a user device and a first network device should be transferred from the first network device to a second network device that is in an idle state; output an instruction to cause the second network device to exit the idle state and communicate with the user device; determine that the second network device is unused or underutilized; and output, based on determining that the second network device is unused or underutilized, an instruction to cause the second network device to reenter the idle state.
