Wireless Identifier Information Transmission for Search Time Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless Local Area Networks (LANs), setting a long maximum waiting time for search processes can lead to decreased usability due to prolonged times from the end of search to the start of communication with a desired apparatus, especially in networks with a small number of devices.
Innovation Solution
A method where the first information processing apparatus transmits identifier information including the maximum number of connections it can establish through wireless communication to the second information processing apparatus, allowing the second apparatus to set an appropriate waiting time based on this information for searching for a partner apparatus, thereby reducing the search time and maintaining usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long maximum waiting time is set in the search packet, then the search process can appropriately search for the partner apparatus in the network, but the time from the end of the search to the start of communication with a desired partner apparatus increases, decreasing usability
Solution Approach 1:
The patent applies dynamics by making the maximum waiting time adjustable rather than fixed. The waiting time is dynamically set based on the maximum number of connections the access point can establish, allowing the system to adapt between a longer waiting time for reliable search in large networks and a shorter waiting time for quick connection in small networks
Solution Approach 2:
The patent changes the parameter of maximum waiting time based on the maximum number of connections. By transmitting the maximum connection number in identifier information and having the searching apparatus set the waiting time based on this parameter, the system optimizes the balance between search reliability and connection speed
2Reliability
If a long maximum waiting time is set to avoid congestion in response packet communication, then all apparatuses can respond properly, but the transition from search to communication is delayed
Solution Approach 1:
The patent changes the waiting time parameter based on the maximum connection capacity of the access point. When the maximum number of connections is small, a shorter waiting time is set to accelerate connection establishment. When the maximum number of connections is large, a longer waiting time ensures reliable response communication without congestion
Solution Approach 2:
The system dynamically adjusts the waiting time parameter based on real-time network conditions (maximum connection capacity), making the search process adaptive to different network scales and ensuring both reliability and efficiency
