Probe Device for Broadband Wireless Performance Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadband wireless systems lack effective methods for collecting, storing, and reporting performance information, focusing primarily on fault management rather than performance management, which hinders the ability of service providers to monitor system performance from the customer's perspective.
Innovation Solution
A probe device is deployed to execute various tests, such as web surfing, bulk file transfer, and bit-error-rate tests, to measure performance and store relevant data, enabling the transmission and retrieval of performance information like delay, download speed, and packet errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broadband wireless systems focus primarily on fault management, then system reliability is improved, but performance monitoring capability deteriorates
Solution Approach 1:
The patent segments the management functions by introducing a dedicated performance management module that operates independently from the fault management system. This module specifically handles performance information collection, storage, and reporting, while the fault management system continues to handle reliability aspects. This segmentation resolves the contradiction by allowing both functions to operate optimally without interfering with each other.
Solution Approach 2:
The patent introduces an intermediary performance management module that acts as a mediator between the fault management system and the network operations. This intermediary collects performance information through probes and tests, stores it in dedicated databases, and reports it separately, preventing the loss of performance information while maintaining the existing fault management focus on reliability.
2Measurement precision
If comprehensive performance tests are executed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal probe device that can execute multiple types of performance tests (web surfing tests, file transfer tests, delay tests, error rate tests) through a standardized interface. This multi-functional probe maintains high measurement precision across different test types while reducing overall device complexity by using a single versatile testing instrument rather than multiple specialized devices.
Solution Approach 2:
The patent achieves comprehensive performance measurement by changing test parameters (test types, measurement intervals, data volumes) rather than adding complex hardware. The probe device maintains precision by adjusting software-controlled parameters such as test duration, packet sizes, and measurement frequencies, avoiding the need for increasingly complex physical equipment.
Data Source
AI summary
A probe device tests a broadband wireless system. The probe device receives an instruction to execute a plurality of tests. The probe device then executes the plurality of tests to measure performance of the broadband wireless communication system based on the instruction. The probe device determines performance information from the plurality of tests. The probe device stores the performance information in a memory of the probe device.
