Radio Access Network Data Volume Reporting for Duplication Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio access network data volume reporting solutions fail to effectively handle duplication transmission in 4G and 5G systems, particularly in carrier aggregation and dual connectivity scenarios, leading to unsatisfied operator needs.
Innovation Solution
A method and system for generating and reporting radio access network data volume, which includes acquiring data volume information about data radio bearers, generating reports that distinguish between counted and uncounted duplicated parts, and sending these reports to the core network, utilizing configuration information to determine reporting granularity and handling different radio access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duplication transmission is implemented in carrier aggregation or dual connectivity, then data transmission reliability and availability are improved, but data volume reporting accuracy deteriorates because the same data is transmitted multiple times across different serving cells or nodes
Solution Approach 1:
The patent segments the data volume reporting into different categories: counted data volume (for primary serving cells or first nodes) and uncounted data volume (for secondary serving cells or second nodes). This segmentation allows the system to accurately track data volumes without double-counting duplicated transmissions, resolving the contradiction between transmission reliability and reporting accuracy.
Solution Approach 2:
The patent introduces a configuration parameter (first parameter) as an intermediary mechanism to control whether duplicated data volume should be counted or not. This parameter acts as a mediator between the duplication transmission function and the data volume reporting function, allowing operators to flexibly control reporting behavior based on specific network scenarios.
2Quantity of substance
If data volume reporting covers all serving cells in duplication transmission, then reporting completeness is improved, but data volume double-counting occurs leading to reporting accuracy deterioration
Solution Approach 1:
The patent divides the reporting scope into primary and secondary serving cells, applying different counting rules to each. Primary serving cells have their data volume counted, while secondary serving cells have their data volume marked as uncounted. This segmentation ensures completeness by covering all serving cells while preventing double-counting through selective reporting.
Solution Approach 2:
The patent applies different reporting qualities to different serving cells based on their roles in duplication transmission. Primary serving cells use full counting, while secondary serving cells use exclusion from counting. This local differentiation allows comprehensive reporting without introducing errors from double-counting duplicated data.
3Adaptability or versatility
If the reporting solution is extended to support multiple radio access technologies in dual connectivity, then system adaptability is improved, but solution complexity increases
Solution Approach 1:
The patent designs a universal reporting mechanism that works across different radio access technologies (e.g., LTE, NR) and network configurations (carrier aggregation, dual connectivity). By using a standardized set of parameters and a unified counting logic, the system can handle multiple RATs without requiring separate complex solutions for each technology, thus improving adaptability while controlling complexity.

AI summary
Provided are a radio access network data volume report method, apparatus and system, and a computer-readable storage medium. The radio access network data volume report method includes that a node acquires data volume information about a data radio bearer, where the data volume information about the data radio bearer includes data volume of a packet data convergence protocol protocol data unit (PDCP PDU) or a packet data convergence protocol service data unit (PDCP SDU) generated by a packet data convergence protocol (PDCP), and data volume of a PDCP PDU or a PDCP SDU issued by the PDCP to radio link control; the node generates a radio access network data volume report according to the data volume information about the data radio bearer, where the radio access network data volume report includes at least one of radio access network data volume of a granularity unit where a duplicated part is not counted, radio access network data volume of the granularity unit where the duplicated part is counted, or radio access network data volume of the duplicated part of the granularity unit; and the node sends the radio access network data volume report to a core network.
