Electronic Device AP Switching Control for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face issues with properly switching access points (APs) as a connection destination, leading to potential problems or disconnections when switching APs, especially in power-saving modes where clock frequencies are lowered, affecting communication efficiency and reliability.
Innovation Solution
An electronic device with a processor and memory that receives AP change requests and controls the switching of access points based on specific modes, such as a first mode for normal operation and a second mode with a lower clock frequency, ensuring proper AP switching by determining the request reason and maintaining or rejecting the switch based on operational states and security settings.

Engineering Contradiction Analysis
1Productivity
If the electronic device switches access point based on AP change request, then communication efficiency is improved, but connection stability deteriorates when in power-saving mode with lower clock frequency
Solution Approach 1:
The patent applies dynamics by making the AP switching behavior adaptive to the device's operational mode. The control unit dynamically adjusts the response to AP change requests based on whether the device is in a normal mode or a power-saving mode with lower clock frequency, allowing the system to optimize between communication efficiency and connection stability according to current operational conditions
Solution Approach 2:
The patent changes the parameter of clock frequency to define different operational modes. By detecting whether the clock frequency is at a lower level (power-saving mode) or normal level, the system adjusts its AP switching behavior accordingly, preventing switches during power-saving mode to maintain connection stability while allowing switches during normal mode to optimize communication efficiency
2Use of energy by moving object
If the electronic device operates in power-saving mode with lower clock frequency, then power consumption is reduced, but AP switching reliability deteriorates
Solution Approach 1:
The system dynamically adjusts AP switching behavior based on the operational mode detected through clock frequency monitoring. When in power-saving mode with lower clock frequency, the control unit suppresses AP switching operations to prevent time-outs and connection failures, while still maintaining the power-saving benefits of lower power consumption
Solution Approach 2:
The patent applies preliminary anti-action by proactively preventing AP switching operations when the device is detected to be in power-saving mode. The control unit checks the operational mode before processing AP change requests and rejects switches that would likely fail due to the lower clock frequency, thereby preventing connection instability before it occurs

AI summary
An electronic device includes at least one memory storing instructions and at least one processor. The at least one memory and the at least one processor are configured to receive a change request of an access point serving as a connection destination from a connected first access point, and control, in a case where the electronic device is in a first mode, out of the first mode and a second mode in which a clock frequency of the at least one processor is lower than in the first mode, to perform connection destination change processing based on the change request, and in a case where the electronic device is in the second mode, not to perform the connection destination change processing based on the change request.
