User Equipment Charging Trigger for Indoor Coverage Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting indoor telecommunication network coverage issues are inadequate, as they rely on GPS-based Location Based Services that fail in indoor environments due to satellite signal limitations and consume significant user equipment resources, making it difficult for operators to efficiently measure and improve indoor coverage.
Innovation Solution
A method where user equipment, upon detecting a charging event, transmits network-related information, including signal strength and location, to the telecommunication network, allowing for the estimation and improvement of indoor coverage without the need for intrusive field measurements, leveraging regular battery charging events as an implicit indication of indoor location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-based Location Based Services are used to detect coverage zones, then location information can be obtained, but the method fails in indoor environments and consumes large amounts of user equipment capabilities
Solution Approach 1:
The system uses the user equipment's own battery charging events as a trigger mechanism to collect and transmit network measurement data. The charging status itself serves as the triggering condition for data collection, eliminating the need for separate location-based triggering mechanisms that consume additional resources.
Solution Approach 2:
The patent introduces battery charging status as an intermediary indicator to infer indoor location. Instead of directly using GPS or complex location services, the system uses the charging event as a proxy that indicates the device is likely indoors, thereby enabling coverage measurement without direct location tracking.
2Measurement precision
If field radio measurement campaigns are conducted to measure indoor coverage, then accurate coverage data can be obtained, but the process is costly and intrusive
Solution Approach 1:
User equipment devices perform self-measurement of network coverage parameters when charging. The devices automatically collect network related information such as signal strength and transmit this data to the network operator, eliminating the need for operator-conducted field measurement campaigns.
Solution Approach 2:
Instead of conducting physical field measurement campaigns, the system uses copies of measurement data collected automatically by user equipment during normal charging operations. These data copies provide sufficient information for coverage analysis without requiring actual field deployment of measurement equipment.
3Reliability
If network operators conduct extensive field measurement campaigns to improve indoor coverage, then coverage quality can be optimized, but the process requires significant resources and time
Solution Approach 1:
The system enables continuous collection of coverage data through ongoing battery charging events. Since charging occurs regularly in user routines, the system continuously accumulates measurement data over time, providing ongoing coverage information without requiring periodic intensive measurement campaigns.
Solution Approach 2:
The system performs preliminary data collection during normal charging operations before analysis is needed. Measurement data is gathered in advance during routine charging events, prepared and stored ready for subsequent coverage analysis and optimization decisions.
