Short QoS Flow Identifier Mapping for 5G Transmission Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the existing methods for data transmission are inefficient due to the high overhead caused by the use of long QoS flow identifiers, which hinders flexible and efficient information transmission across different data bearers.
Innovation Solution
A method that queries and adds a shorter QoS flow identifier into the packet header based on stored configuration information, reducing overhead and improving flexibility in data transmission by using a configuration list to map first QoS flow identifiers to shorter second QoS flow identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If long QoS flow identifiers are used in packet headers, then QoS flow identification accuracy is improved, but transmission overhead increases
Solution Approach 1:
The patent changes the parameter of QoS flow identifier length from long to short by introducing a shortened identifier mechanism. The configuration information stores mapping relationships between original QoS flow identifiers and shortened identifiers, allowing the system to use shorter identifiers in packet headers while maintaining accurate QoS flow identification through the pre-established mapping relationship.
2Loss of energy
If shorter QoS flow identifiers are used, then transmission overhead is reduced, but QoS flow identification capability deteriorates
Solution Approach 1:
The patent introduces configuration information as an intermediary that stores mapping relationships between long QoS flow identifiers and short QoS flow identifiers. This intermediary mechanism allows the system to use short identifiers in packet headers while maintaining the ability to accurately identify QoS flows by referencing the pre-stored mapping relationships in the configuration information.
3Reliability
If QoS flow identifiers are added to packet headers, then data transmission reliability is improved, but packet header length increases
Solution Approach 1:
The patent changes the parameter of identifier length within the packet header by replacing long QoS flow identifiers with short QoS flow identifiers. The configuration information maintains the necessary mapping relationships to ensure reliable data transmission, thus reducing packet header length while preserving transmission reliability.
