Solution Overview

Problem

Current methods for determining available bandwidth in wireless communication systems are time-consuming, requiring devices to communicate with central servers to gather information about nodes, which affects user experience.

Innovation Solution

A method where user devices measure the time interval between frames transmitted by nodes and determine the number of associated devices to calculate a load measure, allowing them to select the node with the lowest load for optimal connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If current methods are used to determine available bandwidth by communicating with central servers, then information about node bandwidth can be obtained, but the process becomes time-consuming and affects user experience

Engineering Contradiction:
Improvebandwidth informationVSAvoidtime to determine bandwidth
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The user device autonomously determines the load measure of wireless nodes by directly analyzing transmitted frames without requiring communication with central servers. The device extracts timing information and device count information from frames independently, eliminating the need for server-based bandwidth information gathering and significantly reducing the time required.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors and analyzes frames transmitted by wireless nodes in real-time, maintaining up-to-date load measure information proactively. This preliminary action ensures that when a user device needs to connect or switch nodes, the bandwidth information is already available, eliminating the need for time-consuming on-demand queries to central servers.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If user devices autonomously determine load measures by analyzing transmitted frames, then bandwidth information can be obtained quickly, but the device must process and analyze frame data

Engineering Contradiction:
Improvespeed of bandwidth determinationVSAvoidframe analysis processing
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The user device extracts only the specific timing information and device count information needed for load measure calculation from the transmitted frames, rather than processing the entire frame content. This selective extraction approach enables quick bandwidth determination while minimizing the processing complexity by focusing only on the relevant data elements.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A method for determining a load measure associated with a wireless communications node, such as a Wi-Fi access point or cellular base station, is described. A time interval measure representing a time interval between frames transmitted by a node is determined, and a number of user devices associated with the node is determined based on information in the frames transmitted by the node. A load measure associated with the node is determined, based at least on the number of user devices associated with the node and the time interval measure. Systems and apparatus are also described.
