Access Point Selection for Wireless Client Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless LAN systems, the presence of both high-speed and low-speed communication clients can lead to increased round-trip times due to waiting periods, as high-speed clients may need to wait while low-speed clients perform data communication with an access point.
Innovation Solution
A communication apparatus that functions as an access point, with an information sharing unit, score calculation unit, connection necessity determination unit, and connection processing unit, prioritizes radio communication connections based on the presence of connected clients and their communication speeds to reduce waiting times by preferentially connecting high-speed clients to access points with available connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple clients connect to one access point, then resource utilization is improved, but round-trip time increases due to waiting periods
Solution Approach 1:
The patent segments clients into different categories (high-speed communication clients and low-speed communication clients) and assigns them to different access points based on their communication requirements. This segmentation allows high-speed clients to connect to access points with available capacity, reducing waiting time, while low-speed clients connect to access points where they can utilize resources without causing significant delay to high-speed traffic.
Solution Approach 2:
The patent applies local quality by assigning different connection priorities and resource allocation strategies to different clients based on their specific communication needs. High-speed clients receive preferential treatment in terms of access point selection and resource allocation, while low-speed clients are directed to access points where their communication patterns will have minimal impact on overall system performance.
2Adaptability or versatility
If high-speed and low-speed clients share the same access point, then network coverage is improved, but communication speed deteriorates due to contention
Solution Approach 1:
The patent segments the client base into high-speed and low-speed communication clients, and segments access points into those with available capacity and those currently saturated. This dual segmentation enables high-speed clients to be directed to appropriate access points, ensuring they receive sufficient bandwidth, while low-speed clients are directed to access points where their communication will not significantly impact high-speed traffic.
Solution Approach 2:
The patent introduces an intermediary mechanism (access point selection system) that mediates between client connection requests and access point resources. This intermediary evaluates client communication requirements, current access point status, and compatibility factors to make intelligent matching decisions, ensuring that high-speed clients are connected to access points that can accommodate their bandwidth requirements.
Data Source
AI summary
A communication apparatus according to the present disclosure functions as an access point, transmits/receives information to be shared that should be shared with another access point when a radio communication connection has been requested from a first client, and calculates, for the access point and the other access point, scores that indicate priority as a connection destination of the first client using the information to be shared. Then it is determined whether it is necessary to establish the radio communication connection with the first client based on the above scores and establishes, when it is determined that it is necessary to establish the radio communication connection, the radio communication connection with the first client.
