UE Measurement Log Segmentation for Mobile Network Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing and reporting measurement information from user equipment (UE) to network elements, particularly in wireless communication systems, where large volumes of data can lead to message size limitations and potential blocking of important RRC messages, and may result in invalid measurements if not sent promptly.
Innovation Solution
Implementing a method where the UE sends an availability indicator to the network, followed by partial transmission of measurement information, with the option to split logs when data exceeds thresholds to prevent message size issues, allowing for controlled capacity sharing and reducing the risk of message blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all measurement information is transmitted in a single message from user equipment to network element, then complete measurement data is provided, but message size limitations are exceeded and important RRC messages may be blocked
Solution Approach 1:
The patent divides the measurement information into multiple segments or chunks, each contained in a separate message. The UE transmits these segments sequentially or in parallel, ensuring that no single message exceeds size limitations while maintaining complete measurement data delivery. This segmentation resolves the contradiction by allowing complete information transmission without blocking other RRC messages.
Solution Approach 2:
The patent implements periodic transmission of measurement information segments, where the UE sends data in scheduled intervals rather than attempting to transmit all data at once. This periodic approach ensures that measurement information is delivered completely while preventing message blocking by spacing transmissions appropriately.
2Loss of time
If measurement information is transmitted promptly to avoid invalid measurements, then measurement validity is maintained, but large message sizes may block important RRC messages
Solution Approach 1:
By segmenting measurement information into smaller units, the patent enables prompt transmission of valid measurements without creating excessively large messages that would block the RRC message queue. Each segment can be transmitted quickly, maintaining measurement validity while preserving system reliability.
Solution Approach 2:
The patent transmits measurement information in partial increments rather than waiting to accumulate all data. This partial action approach allows the UE to send valid measurements as soon as they are collected, maintaining timing validity while avoiding message blocking through controlled transmission rates.
3Reliability
If measurement logs are split into multiple messages, then message size limitations are respected, but additional signaling overhead is introduced
Solution Approach 1:
The patent introduces segmentation logic that divides measurement logs into multiple messages with appropriate delimiters and sequence indicators. While this adds some signaling elements, the structured approach ensures message size compliance through systematic division rather than ad-hoc splitting, managing the complexity increase in an organized manner.
Solution Approach 2:
The patent employs intermediary signaling elements such as sequence numbers, segment identifiers, and completion indicators that mediate between the segmentation requirement and protocol simplicity. These intermediaries provide the necessary coordination for split message transmission while keeping the overall protocol structure relatively simple and manageable.

AI summary
A method including causing a plurality of measurements to be performed by a user equipment to provide measurement information; causing a message to be sent from the user equipment to a network element indicating that measurement information is available; and responsive to a message from said network element requesting said measurement information, causing a response to be sent from the user equipment to said network with only some of said measurement information and information indicating that further measurement information is available.
