Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in effectively reporting small data transmission failures in 3GPP networks, which hinders network optimization and quality-of-service verification, as existing methods often require manual testing and lack efficient failure detection mechanisms.
Innovation Solution
An apparatus and method for detecting and reporting small data transmission failures in 3GPP networks, which includes receiving a configuration for a small data transmission procedure, detecting failures based on specific criteria such as cell re-selection, timer expiration, or maximum transmission attempts, and transmitting a failure report to the access node, including reasons and configuration details.

Engineering Contradiction Analysis
1Extent of automation
If manual testing methods are used for failure detection, then testing flexibility is maintained, but testing efficiency and automation level are low
Solution Approach 1:
The system enables self-service automation by having the wireless device automatically detect transmission failures, generate failure reports with detailed information (failure cause, configuration parameters, random access procedure details), and transmit these reports to the network without requiring manual intervention. The device autonomously monitors transmission attempts, detects failures based on predefined criteria, and initiates reporting procedures
Solution Approach 2:
The patent implements feedback mechanisms where failure information is systematically collected from the device and fed back to the network for analysis. The network can request failure reports from devices, and the devices respond with structured failure information including configuration details and failure causes, enabling continuous optimization of transmission parameters and failure detection strategies
2Loss of information
If detailed failure information is collected and reported, then network optimization capability is improved, but signaling overhead and reporting complexity increase
Solution Approach 1:
The failure report is segmented into distinct information elements including failure cause indicators, configuration parameter subsets (only those relevant to the failure), and random access procedure details. This segmentation allows the system to transmit comprehensive failure information in a structured, manageable format that reduces processing complexity while maintaining information completeness
Solution Approach 2:
The system performs preliminary actions by pre-configuring the device with failure detection criteria, reporting triggers, and information collection parameters before failures occur. Configuration parameters and measurement identities are established in advance, enabling the device to automatically capture and report relevant failure information without complex real-time processing decisions
