Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission control methods in 5G networks are not direct enough to meet the varying quality of service (QoS) requirements of different data flows, leading to inefficiencies in resource allocation and transmission quality.
Innovation Solution
A method and device for controlling data transmission by acquiring and applying QoS control information, including bit rate limiting parameters and priority management, to directly manage and adjust data flows, sessions, and radio bearers based on specific QoS requirements, ensuring efficient resource allocation and compliance with QoS standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional scheduling methods are used to control data transmission, then resource allocation can be managed, but the control process is not direct enough to meet varying QoS requirements of different data flows
Solution Approach 1:
The patent segments the data transmission control into flow-level and session-level QoS parameters. Flow-level parameters (priority, guaranteed bit rate, maximum bit rate) are assigned to individual data flows, while session-level parameters (aggregate bit rate) are assigned to sessions. This segmentation enables direct and fine-grained control over different data flows, allowing the network to meet varying QoS requirements effectively.
Solution Approach 2:
The patent introduces and modifies QoS parameters including priority level, guaranteed bit rate (GBR), maximum bit rate (MBR), and aggregate bit rate. By changing and adjusting these parameters dynamically, the system can directly control data transmission characteristics to meet different QoS requirements, transforming the control process from indirect scheduling to direct parameter-based control.
2Adaptability or versatility
If multiple data flows with different QoS requirements are transmitted through a single radio bearer, then resource utilization is simplified, but it becomes difficult to meet specific QoS requirements for each data flow
Solution Approach 1:
The patent segments QoS control into flow-level and session-level mechanisms. Flow-level QoS parameters (priority, GBR, MBR) are configured for each data flow, while session-level aggregate bit rate provides overall control. This segmentation allows multiple data flows with different QoS requirements to be transmitted through a single radio bearer while maintaining specific QoS control, balancing adaptability and complexity.
Solution Approach 2:
The patent implements dynamic QoS control by allowing the network to adjust flow-level and session-level parameters in real-time. The system can dynamically modify priority levels, bit rate guarantees, and maximum rates based on current network conditions and QoS requirements, enabling adaptable control without requiring overly complex static configurations.
3Ease of operation
If QoS control is implemented at the radio bearer level, then control is simplified, but it cannot directly address the varying QoS needs of individual data flows within a bearer
Solution Approach 1:
The patent segments QoS control into two levels: session-level control (aggregate bit rate) and flow-level control (priority, guaranteed bit rate, maximum bit rate). This segmentation maintains simplicity at the session level while providing precise control at the flow level, allowing the system to directly address varying QoS needs of individual data flows without overwhelming complexity.
Solution Approach 2:
The patent applies local quality control by assigning specific QoS parameters (priority, GBR, MBR) to individual data flows rather than applying uniform control to all flows. Each data flow receives tailored QoS settings according to its specific requirements, enabling precise control while maintaining overall system simplicity through hierarchical organization.

AI summary
A method of controlling a data transmission and a device thereof are provided. According to the method, a data sender acquires QoS control information, and controls a data transmission according to QoS control information. In the case that the data sender is a UE, the network side device sends the QoS control information to the UE, so that the UE may control the data transmission according to the QoS control information and may perform the corresponding control onto the data transmission.
