Automatic Channel Following for Stable Device Group Frequency Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication methods in device groups face challenges such as scarcity of spectrum resources, channel conflicts, and the need for frequent disconnection and reconnection during frequency hopping, which affect communication stability and efficiency.
Innovation Solution
A wireless communication method that adjusts the operating frequencies of secondary devices in a device group to match changes in the primary device's frequency, maintaining connections without disconnection and reestablishment, using a mechanism called 'automatic channel following' to synchronize frequency changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the primary device changes frequency for network connection, then the device group can access different network channels, but the secondary device must disconnect and reconnect, causing communication interruptions
Solution Approach 1:
The patent applies preliminary action by having the secondary device proactively scan and prepare to connect to alternative access points before the primary device actually switches frequencies. The secondary device monitors the primary device's frequency changes in advance and pre-establishes connection parameters for potential target frequencies, thus avoiding disconnection interruptions when the frequency switch occurs.
Solution Approach 2:
The patent implements feedback mechanisms where the secondary device continuously monitors the primary device's connection status and frequency changes. When detecting a frequency switch, the secondary device receives feedback about the new frequency and automatically adjusts its connection parameters accordingly, maintaining continuous communication without disconnection.
2Reliability
If the secondary device continuously monitors frequency changes to maintain connection, then connection stability improves, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by having the secondary device perform frequency monitoring and scanning at specific intervals rather than continuously. The device checks for primary device frequency changes at predetermined periods and only activates full scanning when a change is detected, thus maintaining connection stability while significantly reducing energy consumption compared to continuous monitoring.
3Productivity
If the device group uses multiple frequency channels simultaneously, then spectrum resource utilization improves, but channel conflicts increase
Solution Approach 1:
The patent introduces the primary device as an intermediary that coordinates frequency channel selection for the entire device group. The primary device selects appropriate frequency channels for network connection and automatically notifies secondary devices of the selected frequencies, enabling multiple devices to use multiple channels efficiently while the primary device manages to avoid channel conflicts through centralized coordination.

AI summary
A method, apparatus, and device for a device group, a computer program product, and a computer-readable storage medium are provided. The method, targeting a device group containing a primary device and one or more secondary devices, when a frequency of a network connection of the primary device changes, adjusts operating frequencies of the secondary device and the primary device jointly to a same frequency, where the same frequency is a changed frequency of the network connection of the primary device, or another frequency, such that a frequency of a wireless connection between the primary device and the secondary device is enabled to be changed to a first frequency accordingly, thereby maintaining the wireless connection between the secondary device and the primary device without requiring disconnection and reestablishment of the wireless connection between the secondary device and the primary device in response to channel switching of the primary device.
