D2D Resource Acquisition Failure Reporting via MDT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no existing solution for collecting and sending Device to Device (D2D) resource acquisition failure information from Minimization of Drive Test (MDT) enabled User Equipment (UE) to the network side during D2D discovery or communication in radio communication systems, limiting the network's ability to monitor and manage D2D services effectively.
Innovation Solution
An information reporting method and system that enables User Equipment (UE) to receive configuration information for D2D resource acquisition failures, collect, and send relevant information to an evolved Node B (eNodeB), which processes this data to improve network monitoring and user experience by detailing the failure reasons, circumstances, and resource allocation details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If D2D resource acquisition failure information is not collected and reported, then the network side cannot effectively monitor and manage D2D services, but implementing collection and reporting increases system complexity and requires additional signaling overhead
Solution Approach 1:
The patent reuses existing MDT (Minimization of Drive Test) mechanisms and signaling procedures already present in the network for their original purpose, while simultaneously enabling them to collect D2D resource acquisition failure information. This multi-functional use of existing infrastructure avoids adding complex new systems while improving network monitoring capability.
Solution Approach 2:
The UE autonomously collects D2D resource acquisition failure information and reports it to the network side using existing MDT reporting mechanisms. The UE self-manages the information collection process without requiring additional network-side collection infrastructure, reducing overall system complexity while enabling reliable monitoring.
2Productivity
If manual drive test work is reduced through automated information collection, then operational efficiency improves, but the need for sophisticated information collection and processing systems increases complexity
Solution Approach 1:
The patent replaces manual drive test operations with automated information collection through MDT mechanisms. The UE automatically collects D2D resource acquisition failure information and reports it to the network, eliminating the need for manual drive tests while using existing automated signaling infrastructure, thus improving efficiency without significantly increasing system complexity.
Solution Approach 2:
The patent leverages existing MDT parameter structures and reporting frameworks, simply extending them to include D2D resource acquisition failure information. By reusing and extending existing parameters rather than creating new complex information structures, the system achieves automated collection with minimal increase in processing complexity.

AI summary
An information reporting method is disclosed. A User Equipment (UE) receives configuration information for a Device to Device (D2D) resource acquisition failure, the configuration information for the D2D resource acquisition failure being used for a D2D UE with a drive test capability to collect information on the D2D resource acquisition failure in case of the D2D resource acquisition failure, and send the information on the D2D resource acquisition failure. Another information reporting method, an evolved Node B, a UE and a storage medium are also disclosed.
