Wireless Access Point Link Setup Using Compressed Domain Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face delays and increased latency due to high rates of link setup collisions when multiple mobile stations attempt to connect to an access point, leading to network congestion and reduced performance.
Innovation Solution
The method involves transmitting and receiving network domain identifiers from an access point to devices, allowing for faster link setup by broadcasting access response messages and modifying beacon messages based on demand, using compressed beacons, and optimizing association request timing to reduce collisions and enhance network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobile stations attempt to connect to an access point simultaneously, then network availability increases, but link setup collisions increase causing latency
Solution Approach 1:
The access point broadcasts beacon messages containing network domain identifiers and associated service information before actual connection requests are processed. This preliminary action allows mobile stations to prepare connection parameters in advance and reduces the time required for link setup when multiple stations attempt to connect simultaneously.
Solution Approach 2:
The patent segments the network identification process by introducing network domain identifiers that divide the network into multiple domains. This segmentation allows for more efficient association requests and reduces collision probability by organizing the connection process into structured phases with distinct identifier handling.
2Measurement precision
If full network domain identifiers are used in all messages, then identification accuracy is maintained, but signaling overhead increases
Solution Approach 1:
The patent applies different levels of identifier detail to different message types and communication contexts. Full network domain identifiers are used in beacon messages where comprehensive identification is needed, while compressed or abbreviated forms are used in subsequent association and confirmation messages, optimizing the balance between identification accuracy and signaling efficiency.
Solution Approach 2:
The system discards redundant identifier information after the initial network domain identification phase and recovers only the necessary identifier components for maintaining the connection. This reduces signaling overhead in subsequent communications while preserving the accuracy needed for network identification.
