Wireless LAN Station Connection Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless LAN technologies face challenges in efficiently setting connection timing between access points and stations, leading to increased link setup time and congestion, especially as demand for higher throughput and broader bandwidth increases.
Innovation Solution
A method is introduced where a station management entity transmits information about reception conditions and reporting timing of communication setup messages to a MAC layer management entity, which adjusts the transmission timing based on connection priority requirements, optimizing the link setup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connection setup messages are transmitted without coordinated timing control, then stations can initiate connections freely, but link setup time increases and congestion occurs
Solution Approach 1:
The patent implements periodic connection opportunities by defining specific target times when stations are allowed to transmit connection setup messages to the access point. Instead of continuous or random connection attempts, stations synchronize their connection requests to occur at predetermined periodic intervals, thereby reducing congestion and optimizing link setup efficiency.
2Productivity
If multiple stations transmit connection setup messages simultaneously, then connection requests are processed quickly, but congestion and transmission conflicts occur
Solution Approach 1:
The patent segments the connection request process by assigning different target times to different stations or station groups. Each station is configured with a specific target time for transmitting its connection setup message, dividing the simultaneous transmission problem into sequential, non-conflicting transmission slots. This segmentation eliminates transmission conflicts while maintaining efficient connection processing.
3Productivity
If connection timing is distributed across multiple target times, then congestion is reduced, but system complexity increases
Solution Approach 1:
The access point performs preliminary action by pre-configuring and notifying each station of its assigned target time before the connection process begins. This advance notification eliminates the need for complex real-time coordination algorithms during actual connection setup, as stations simply follow their pre-assigned timing schedule, thereby reducing operational complexity while maintaining distributed timing benefits.
Data Source
AI summary
A method for setting connection between an access point and a station is provided. A method includes transmitting, by a station management entity, to a MAC layer management entity included in the station, information about a reception condition for a communication setup message transmitted by the access point and information about a reporting timing of the communication setup message by the MAC layer management entity to the station management entity when the MAC layer management entity receives the communication setup message, and adjusting, by the MAC layer management entity, a transmission timing of the communication setup message to the station management entity according to information about a connection priority requirement included in the communication setup message received by the MAC layer management entity from the access point, and the information about the reporting timing.
