Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual detection of radio coverage in multicellular mobile radio systems is costly and inefficient, especially after changes in building architecture, leading to potential faults and interruptions in telecommunications.
Innovation Solution
A method where base stations in a multicellular mobile radio system are switched consecutively into a measuring operating mode, with field strength data measured and evaluated by an evaluation unit, allowing for automatic detection and evaluation of radio coverage without personnel deployment, including synchronicity quality assessment and geographical mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual detection with metering units is used, then radio coverage can be detected, but costs increase extraordinarily
Solution Approach 1:
The base stations automatically perform radio coverage detection by measuring field strength of adjacent base stations, eliminating the need for external metering units and manual measurement crews. The system serves itself by using existing infrastructure (base stations) to perform the detection function that previously required separate expensive equipment and personnel.
Solution Approach 2:
Base stations are made multi-functional by enabling them to perform both normal communication operations and radio coverage detection. The same base station infrastructure is used for both serving customers and measuring radio field illumination, eliminating the need for dedicated detection equipment.
2Reliability
If manual detection is performed repeatedly after building changes, then radio coverage can be verified, but time and costs increase
Solution Approach 1:
The automatic detection system operates continuously or at regular intervals without interruption to normal base station operations. Multiple base stations are switched consecutively into measuring mode, ensuring continuous monitoring of radio coverage without requiring repeated manual intervention after building changes.
3Extent of automation
If base stations are switched into measuring mode, then automatic detection is achieved, but normal operation is interrupted
Solution Approach 1:
Base stations are switched into measuring operating mode periodically or consecutively rather than simultaneously. Each base station performs measurements at scheduled intervals or in sequence, allowing normal operations to continue in between measurement cycles and minimizing service interruption.
Solution Approach 2:
The detection process is divided into segments where different base stations are measured at different times. By switching base stations consecutively into measuring mode rather than all at once, the system maintains detection capability while preserving normal service capacity during measurement periods.

AI summary
A method and arrangement for detecting a radio coverage in a synchronous multicellular mobile radio system having a multitude of synchronous base stations that are connected to an evaluating unit are provided. All base stations are operated in succession in a measuring operating mod. A respective field intensity of base stations that are locally adjacent and in a normal operating mode is measured, and the respectively measured field intensity data are evaluated by the evaluating unit. This enables a sufficient radio coverage to be determined in a highly cost-effective manner and, optionally, to be corrected.
