Application Layer Measurement Report Segmentation in 5G Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G wireless communication system faces challenges in efficiently managing large application layer measurement reports due to the limitations in data segmentation and transmission, particularly when messages exceed specific size thresholds, which can lead to inefficiencies in data handling and processing.
Innovation Solution
The proposed solution involves a method for application layer measurement reporting based on segmentation, where the system receives and processes RRC messages, segments them if necessary, and transmits these segments via specific radio bearers (SRB1 and SRB4) to ensure efficient handling and reporting, utilizing RRC segmentation when messages exceed maximum supported sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If application layer measurement reports are transmitted as single large messages, then message structure is simple, but transmission efficiency decreases when messages exceed size thresholds
Solution Approach 1:
The patent divides large application layer measurement reports into multiple segmented messages (first RRC message and second RRC message) to be transmitted separately through different radio bearers (SRB1 and SRB4). This segmentation resolves the contradiction by maintaining manageable message structures while improving transmission efficiency through parallel processing and optimized bearer selection for each segment.
2Productivity
If large measurement reports are segmented into multiple messages, then transmission efficiency improves, but system complexity increases
Solution Approach 1:
The patent introduces a segmentation handler that acts as an intermediary between the application layer and the radio bearer layer. This handler automatically performs the segmentation of large measurement reports and manages the mapping to appropriate radio bearers (SRB1 for critical segments, SRB4 for non-critical segments), thereby improving data processing efficiency while abstracting the complexity from the overall system.
3Device complexity
If all measurement report segments are transmitted via the same radio bearer, then bearer management is simple, but latency increases due to sequential transmission
Solution Approach 1:
The patent segments the measurement report into critical and non-critical parts, transmitting them through different radio bearers (SRB1 and SRB4 respectively). This allows parallel transmission paths with different QoS characteristics, reducing overall transmission latency while maintaining manageable bearer management through clear segmentation rules.
Solution Approach 2:
The patent applies different transmission qualities to different segments of the measurement report. Critical segments are transmitted via SRB1 with higher priority and reliability, while non-critical segments use SRB4 with lower priority. This local differentiation of transmission quality reduces latency for critical data without unnecessarily complicating the entire bearer management system.
4Reliability
If measurement reports are transmitted without segmentation, then data integrity is maintained, but handling of large reports becomes inefficient
Solution Approach 1:
The patent segments large measurement reports into multiple controlled transmissions through different radio bearers with appropriate error handling and acknowledgment mechanisms for each segment. This maintains data integrity through verified segment delivery while improving the efficiency of handling large reports through parallel processing and optimized bearer selection.
