Link Control Entities for Granular Data Flow Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular radio systems, the lack of sophisticated data flow control leads to inefficiencies and resource wastage due to the inability to separately manage data flows with varying Quality of Service (QoS) requirements over logical links, resulting in suboptimal data transfer and potential data loss.
Innovation Solution
A system with two types of Link Control (LC) means, where each first-type LC transforms data units into a second-type and vice versa, providing separate control over second-type data units transferred through direct interfaces, eliminating the need for a multiplexer and enabling granular flow control based on QoS requirements and buffer states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a multiplexer is used to transfer multiple second-type DUs through a single interface, then device complexity is reduced, but flow control capability deteriorates because separate flow control for each data unit type becomes impossible
Solution Approach 1:
The patent divides the single interface into multiple separate interfaces, with each interface dedicated to a specific type of second-type DU. This segmentation allows the second-type LC means to independently control the flow of each data unit type based on its QoS requirements, eliminating the flow control limitations imposed by multiplexing while maintaining manageable device complexity through structured interface separation.
2Productivity
If priority-based flow control is implemented, then data transfer efficiency for high QoS requirements is improved, but device complexity increases due to the need for sophisticated control mechanisms
Solution Approach 1:
The patent implements priority-based flow control by assigning different QoS parameters and service classes to different types of second-type DUs. Each interface and corresponding first-type LC means is configured with specific flow control characteristics tailored to the QoS requirements of its associated data units, enabling efficient priority handling without requiring complex centralized control mechanisms across the entire system.
3Adaptability or versatility
If multiple first-type LC means transform different first-type DUs into second-type DUs, then adaptability to different data types is improved, but flow control granularity deteriorates when using a single shared interface
Solution Approach 1:
The patent establishes a one-to-one correspondence between first-type LC means and second-type LC means interfaces. Each first-type LC means that transforms a specific first-type DU is directly connected to a dedicated interface on the second-type LC means, preserving the ability to separately control and manage the flow of each data unit type while maintaining system adaptability to handle multiple data formats and protocols.
