Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional radio link failure reporting methods are used, then the reporting process is simple, but the precision of failure location identification is insufficient
Solution Approach 1:
The failure information message is segmented into multiple distinct components: base station identifier, frequency identifier, and positioning information. This segmentation allows each element to be independently processed and analyzed, improving identification precision while maintaining manageable system complexity through modular information handling.
Solution Approach 2:
The patent adds a spatial dimension to failure reporting by incorporating positioning information (latitude, longitude, altitude) alongside traditional identifiers. This dimensional expansion transforms the reporting from abstract identification to precise spatial localization, enabling accurate failure location identification without overwhelming system complexity.
2Ease of repair
If detailed failure information is reported, then troubleshooting capability is improved, but the time and complexity of information processing increases
Solution Approach 1:
The endpoint device automatically collects and prepares failure information (base station identifier, frequency identifier, positioning data) at the moment of failure detection, before troubleshooting begins. This preliminary action ensures all necessary data is immediately available, improving troubleshooting capability while minimizing additional processing time since the information is ready in advance.
Solution Approach 2:
The detailed failure information is fed back to the network side, enabling rapid diagnosis and targeted optimization. This feedback mechanism improves troubleshooting capability by providing actionable data, while the structured format of the feedback (pre-defined identifiers and positioning fields) minimizes processing time through efficient data interpretation.
3Measurement precision
If positioning information is included in failure reports, then network optimization precision is enhanced, but the data transmission load increases
Solution Approach 1:
Positioning information is included specifically in failure reports where it is most needed - at the location of radio link failures. This local application of enhanced data quality improves network optimization precision at critical points without requiring all transmissions to carry additional data, thereby limiting the increase in overall data transmission volume.

AI summary
Example methods, computer-readable media, and endpoint devices for transmitting a failure information message containing a base station identifier, a frequency identifier, and location information of the endpoint device associated with a radio link failure are described. For instance, a processing system of an endpoint device including at least one processor may detect a radio link failure for a radio link between the endpoint device and a base station of a cellular network, determine location information of the endpoint device, the location information includes at least a coordinate position of the endpoint device, and determine a base station identifier that identifies the base station and a frequency identifier associated with a frequency of the radio link. The processing system may further transmit a failure information message containing the base station identifier, the frequency identifier, and the location information of the endpoint device.
