Solution Overview

Problem

Wireless communication networks face challenges in achieving fast initial link setup due to increased latency and network congestion caused by multiple devices attempting to connect simultaneously, leading to packet collisions and reduced network performance.

Innovation Solution

The method involves transmitting and receiving network domain identifiers from an access point to devices, allowing for reduced signaling during link setup by using shorter bit sequences in access request and response messages, and dynamically modifying broadcast frequencies based on demand to minimize congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple devices attempt to connect to the network simultaneously, then network connectivity is established, but latency increases and network congestion occurs

Engineering Contradiction:

Improvelink setup speedVSAvoidlink setup latency

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The access point transmits network domain identifiers in advance during beacon frames before devices need to connect. This preliminary transmission of identification information allows devices to quickly identify and connect to the appropriate network domain without delayed signaling exchanges, directly reducing link setup latency while maintaining the ability to handle multiple simultaneous connections

Inventive Principle:

Principle #10Preliminary action

2Reliability

If standard network identifiers are used in access requests, then network services can be established, but signaling overhead increases

Engineering Contradiction:

Improvenetwork service establishmentVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies different identifier formats based on the specific communication context: full network domain identifiers are transmitted by the access point in beacon frames, while devices use shortened identifiers derived from these in their access requests. This local adaptation of identifier length to the specific signaling direction reduces overall overhead while maintaining reliable network service establishment

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Devices create shortened copies of the network domain identifiers received from the access point. These compressed identifier copies are used in access request messages, preserving the essential identification information needed for reliable service establishment while significantly reducing the signaling overhead compared to transmitting full identifiers in both directions

Inventive Principle:

Principle #26Copying
