Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drive test methods for TDD wireless network communication systems are labor-intensive and limited to outdoor public areas, making it difficult to optimize network coverage in indoor and private locations where users are present, thus increasing network construction and maintenance costs.
Innovation Solution
A measurement method and device where user equipment in TDD standard wireless network communication systems autonomously records and reports system parameters to the base station, allowing for network measurement in previously inaccessible areas, reducing manual effort and enhancing coverage optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual drive test is conducted to measure network coverage quality, then network optimization can be performed, but it requires a lot of manpower and time, increasing operator costs
Solution Approach 1:
User equipment automatically performs network measurement and reporting functions without manual intervention. The UE self-configures measurement parameters, autonomously measures system parameters, and automatically reports results to the base station, eliminating the need for manual drive test operations while maintaining measurement accuracy
Solution Approach 2:
The patent replaces the mechanical manual drive test system with an automated electronic measurement system. Instead of human operators physically driving vehicles with test equipment, the system uses software-controlled automated measurement and reporting mechanisms embedded in user equipment, substituting manual mechanical operations with electronic automation
2Area of stationary object
If manual drive test is conducted outdoors, then network coverage in public areas can be measured, but it cannot be performed indoors or in private areas
Solution Approach 1:
The patent makes user equipment serve multiple functions: it performs both normal communication functions and network measurement functions. This multi-functionality allows the measurement system to operate universally across all locations where UE can connect to the network, including indoor and private areas where traditional manual drive tests cannot access
Solution Approach 2:
The patent uses user equipment as an intermediary device that can access areas inaccessible to manual drive test vehicles. The UE acts as a mobile measurement platform that can penetrate into buildings and private spaces, collecting network data from locations that would otherwise be unreachable by traditional outdoor drive test methods
3Extent of automation
If user equipment autonomously records and reports system parameters, then automatic data collection is achieved, but device complexity increases
Solution Approach 1:
The patent merges network measurement functions with the existing user equipment architecture. Instead of adding separate dedicated measurement devices, the measurement capabilities are integrated into the UE's existing communication stack, combining multiple functions into a unified system that reduces overall complexity while achieving automation
Solution Approach 2:
The user equipment is designed to perform multiple functions simultaneously: normal communication, system parameter measurement, data recording, and automated reporting. This multi-functionality allows a single device to handle diverse tasks without requiring separate specialized equipment for each function, managing complexity through functional integration
Data Source
AI summary
A measurement method and device for wireless network communication system is disclosed. The method enables operators to use recording information to detect whether there is any problem in network and to perform some necessary optimizing work by enabling user equipment (UE) to automatically record some measurement logs and to periodically report them to the network. Because the information is automatically collected by the UE, the method effectively reduces the workload and cost devotion which is needed for network measurement by manual road measurement. The method enables the operators to obtain measurement information of geography areas that can not be obtained in ordinary road measurement because the UE is randomly distributed at any position in the network.
