Communication Apparatus Dynamic Discovery Window Frequency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication apparatuses using Neighbor Awareness Networking (NAN) face challenges in appropriately controlling the frequency of communication during the discovery window (DW), which can interfere with normal Wi-Fi communication, leading to packet loss and delays, particularly when both types of communication are used simultaneously.
Innovation Solution
A communication apparatus with a control unit that adjusts the execution frequency of the discovery window communication based on the establishment of connections using other communication methods, such as normal Wi-Fi, to reduce interference and maintain optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the execution frequency of discovery window communication is increased to improve service discovery capability, then the service discovery efficiency is improved, but the packet loss and delays in normal Wi-Fi communication increase
Solution Approach 1:
The patent applies dynamics by making the execution frequency of discovery window communication adjustable rather than fixed. The control unit dynamically changes the frequency based on connection status: using a first (higher) frequency when no other connections exist, and a second (lower) frequency when other connections are established. This dynamic adjustment resolves the contradiction by adapting the service discovery efficiency to match current communication needs while preventing interference with active connections.
Solution Approach 2:
The patent changes the parameter of execution frequency based on connection status. By monitoring whether other communication connections are established, the system switches between two frequency parameters (first frequency and second frequency). This parameter change strategy allows the system to optimize service discovery when possible while ensuring reliable normal Wi-Fi communication when needed, thus resolving the technical contradiction.
2Productivity
If the discovery window communication is executed at high frequency to improve neighbor awareness networking performance, then the NAN communication performance is improved, but interference with other communication methods increases
Solution Approach 1:
The system dynamically adjusts the NAN communication frequency based on the presence of other communication connections. When other connections are detected, the control unit automatically reduces the discovery window execution frequency, thereby reducing electromagnetic interference and packet conflicts. When no other connections exist, the system increases frequency to optimize NAN performance, thus resolving the contradiction between performance and interference.
Solution Approach 2:
The patent implements feedback by continuously monitoring the connection status of other communication methods and using this information to adjust the discovery window execution frequency. The control unit receives feedback about active connections and modifies the NAN communication parameters accordingly, creating a closed-loop control system that balances NAN performance with interference reduction.
3Reliability
If the discovery window communication frequency is reduced to minimize interference with normal Wi-Fi, then packet loss is reduced, but service discovery capability deteriorates
Solution Approach 1:
The system uses dynamic frequency adjustment to resolve this contradiction. Rather than using a fixed low frequency that would always compromise service discovery, the system switches between high and low frequencies based on real-time connection status. This ensures that service discovery capability is maximized when interference is not an issue, while reliability is prioritized when other communications are active.

AI summary
A communication apparatus is provided which includes a control unit configured to perform control so that an execution frequency of predetermined communication in a state in which a connection using a communication method other than a Neighbor Awareness Network is established is lower than an execution frequency of the predetermined communication in a state in which a connection using the communication method other than the Neighbor Awareness Network is not established.
