User Equipment Logged Measurement Reporting Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE networks, logged measurements from terminals are often not reported to the network in a timely or urgent manner, leading to potential loss of important data during minimization of drive tests (MDT), as the network may not send a command for reporting or may delay it, resulting in resource wastage and inefficiency.
Innovation Solution
A method and apparatus where user equipment (UE) determines the necessity of reporting logged measurements based on criteria such as remaining validity timer, buffer space, battery level, and other conditions, and transmits a reporting indicator to the base station, allowing the network to identify urgency and importance of the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network waits to send a reporting command for logged measurements, then network control is maintained, but the logged measurements may be lost due to delays
Solution Approach 1:
The terminal performs preliminary actions by determining whether reporting of logged measurements is needed and transmitting a reporting indicator before the network sends a reporting command. This allows the terminal to proactively identify and flag important measurements, ensuring they are not lost due to network delays in sending reporting commands.
2Loss of information
If the terminal continuously reports logged measurements, then data completeness is improved, but network resources are wasted
Solution Approach 1:
The terminal applies local quality by selectively determining whether reporting is needed based on specific conditions (such as buffer status, measurement importance, or network state) rather than uniformly reporting all measurements. This ensures that only measurements meeting certain criteria are flagged for reporting, optimizing the balance between data completeness and resource efficiency.
3Measurement precision
If the terminal stores logged measurements for later reporting, then reporting accuracy is improved, but data loss risk increases
Solution Approach 1:
The terminal implements feedback by continuously monitoring storage conditions and determining when reporting is needed based on current state assessments. This feedback mechanism allows the terminal to adjust reporting timing dynamically, ensuring that measurements are reported before storage capacity is exhausted or validity periods expire, thus maintaining both precision and reliability.
Data Source
AI summary
The present invention provides an apparatus and method of reporting logged measurements in a wireless communication system. User equipment receives an MDT (Minimization of Drive Tests) configuration from a base station, and logs a measurement on the basis of the MDT configuration in order to collect logged measurements. The user equipment determines whether the logged measurement needs to be reported. If it is determined that the logged measurement needs to be reported, the user equipment transmits to the base station a report indicator indicating the need for reporting of the logged measurement.
