Wireless Station Application Control via Link Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless systems do not effectively select and control applications based on the wide-ranging link status, including communication environment and received signal strength, which limits adaptability in environments like public wireless LAN services where communication quality varies.
Innovation Solution
A station (STA) that obtains link information including identification of connected access points and communication environment, using an action profile to select and control applications based on this information, allowing adaptive operation and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a previously set application is booted irrespective of link rate to ensure application availability, then application accessibility is improved, but communication efficiency deteriorates because the application cannot adapt to varying link conditions
Solution Approach 1:
The patent implements dynamic application boot control by continuously monitoring link status parameters (received signal strength indication, communication quality) and automatically selecting or switching applications based on current link conditions. This transforms the static application boot mechanism into a dynamic system that adapts to varying communication environments, resolving the contradiction between ensuring application availability and maintaining communication efficiency.
Solution Approach 2:
The system changes operational parameters by adjusting application selection and configuration based on link rate and communication quality thresholds. Different applications are booted or activated according to specific parameter ranges (e.g., high-speed applications when link quality is good, low-power applications when link quality is poor), enabling the system to optimize communication efficiency while maintaining accessibility.
2Productivity
If application operation is changed according to link rate to improve communication efficiency, then productivity is improved, but system complexity increases due to multiple application configurations
Solution Approach 1:
The patent reduces system complexity by pre-configuring application profiles and selection criteria during system setup. The link status thresholds, application mappings, and switching rules are established in advance, allowing the runtime system to simply evaluate pre-defined conditions and execute corresponding actions without complex real-time decision-making logic.
Solution Approach 2:
The system implements self-service through automatic application selection and switching based on monitored link conditions. The STA autonomously evaluates its own link status and selects appropriate applications without requiring manual intervention or complex external control, simplifying the overall system architecture while maintaining adaptive communication efficiency.
3Reliability
If existing systems monitor link status to control application booting, then reliability is improved by preventing communication failures, but adaptability deteriorates because applications cannot be optimized for different communication environments
Solution Approach 1:
The patent implements a universal application selection mechanism that handles multiple communication environments and link conditions through a single integrated system. The same STA can adaptively select from multiple applications based on various link parameters (signal strength, quality, rate), providing both reliability through failure prevention and adaptability through environment-specific optimization within one unified framework.
Data Source
AI summary
An application to be booted is selected and operation of the application is controlled according to status of a link between an access point and a station. A station (STA) which can be connected to an access point (AP) includes a link information obtaining procedure which obtains link information including an identifier of the AP to which the STA is connected while the STA is connected to the AP and an application control procedure which selects an application to be booted according to the link information by referring to an action profile in which an identifier of the link information and an application to be booted are related and registered.
