NAN Cluster Merge Deactivation for Wireless Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In proximity communication networks using the NAN communication standard, overlapping NAN clusters can cause data communication cutoffs due to the merging of electronic devices between clusters with different synchronization information, leading to degraded communication quality.
Innovation Solution
An electronic device is equipped with a processor and wireless communication circuit that forms a NAN cluster and transmits a short-range wireless signal to deactivate the NAN cluster merge function of external devices, preventing them from merging into other clusters, thus maintaining communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic devices are allowed to merge between overlapping NAN clusters based on cluster grade, then network adaptability is improved, but data communication reliability deteriorates due to synchronization conflicts
Solution Approach 1:
The patent applies preliminary anti-action by transmitting a deactivation signal before device merging occurs. The signal preemptively disables the NAN cluster merge function in external devices, preventing synchronization conflicts and data communication cutoffs that would otherwise occur during cluster transitions. This anticipatory measure eliminates the harmful effect before it can manifest.
Solution Approach 2:
The patent introduces an intermediary signal (deactivation signal) that mediates between the NAN cluster management system and external devices. This signal acts as a controller that regulates the merge function, allowing the system to maintain adaptability while preventing reliability issues through controlled intervention.
2Use of energy by moving object
If devices maintain sleep state outside discovery window to reduce power consumption, then energy efficiency is improved, but communication responsiveness worsens during cluster transitions
Solution Approach 1:
The patent applies preliminary action by transmitting the deactivation signal during the discovery window when devices are already awake and communicating. This ensures devices receive the merge function deactivation instruction before potential cluster transitions occur, maintaining both power efficiency (by staying in sleep mode otherwise) and responsiveness (by being alert during discovery windows for signal reception).
