QoS Control for 5G Relay Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, configuring QoS parameters for relay and remote terminal devices to meet end-to-end QoS requirements is challenging, leading to difficulties in satisfying service requirements such as video transmission delays.
Innovation Solution
A method for QoS control that involves the first terminal device obtaining and configuring first and second QoS information to satisfy end-to-end QoS requirements, allowing it to act as an intermediate node for communication between the second terminal device and the external network, ensuring that the QoS parameters for both the terminal device and the external network are aligned with the required service standards.

Engineering Contradiction Analysis
1Reliability
If QoS parameters are configured for relay and remote terminal devices in 5G networks, then the quality of service for services like video transmission is improved, but the complexity of configuring and aligning QoS parameters across multiple devices and network interfaces increases
Solution Approach 1:
The patent introduces a network device as an intermediary that receives QoS requirements from the second terminal device and determines appropriate QoS parameters. This mediator coordinates the QoS configuration between the relay terminal device, remote terminal device, and external network, simplifying the overall configuration process while ensuring end-to-end QoS requirements are met.
Solution Approach 2:
The patent segments the QoS configuration into separate components: first QoS information for the relay terminal device and second QoS information for the remote terminal device. This segmentation allows each device to be configured independently with specific parameters tailored to its role in the communication path, reducing the complexity of managing a single unified QoS configuration.
2Reliability
If separate QoS parameters are configured for relay and remote terminal devices, then the end-to-end QoS requirements can be satisfied, but the difficulty of detecting and measuring the appropriate parameters increases
Solution Approach 1:
The patent implements a feedback mechanism where the network device receives QoS requirements from the terminal devices and determines appropriate QoS parameters based on this feedback. The configured QoS information is then provided back to the relevant devices, creating a closed-loop system that ensures the parameters are appropriately detected and measured to meet end-to-end requirements.
Solution Approach 2:
The network device performs preliminary determination of QoS parameters before actual data transmission occurs. By pre-configuring the first and second QoS information based on anticipated requirements, the system avoids the complexity of real-time parameter detection and adjustment during transmission.
3Loss of time
If QoS information is obtained and configured for both terminal devices, then transmission delays are reduced and service quality is enhanced, but the device complexity and configuration overhead increase
Solution Approach 1:
The patent merges the QoS configuration process into a unified procedure where the network device determines both first and second QoS information in a single operation. This combining of configuration tasks reduces the overall overhead compared to separate configuration processes, while still achieving the time reduction benefits of optimized QoS parameters.

AI summary
A method for quality of service (QoS) control, an apparatus, and a readable storage medium are provided. The method includes the following. A first terminal device receives first information provided by a second terminal device, where the first information includes an end-to-end QoS requirement of a service which is initiated by the second terminal device and to be communicated to an external network via the first terminal device. According to the end-to-end QoS requirement, the first terminal device obtains first QoS information of communication between the first terminal device and the second terminal device and second QoS information of communication between the first terminal device and the external network, where the end-to-end QoS requirement is satisfied by the first QoS information and the second QoS information. As such, it is possible to configure for the first terminal device the second QoS information that satisfies the end-to-end QoS requirement of the service, thereby ensuring a QoS of the service which is initiated by the second terminal device. The first terminal device provides the first QoS information to the second terminal device, such that the second terminal device obtains the first QoS information, and as such, it is possible to configure for the second terminal device the first QoS information that satisfies the end-to-end QoS requirement of the service, thereby ensuring a QoS of the service which is initiated by the second terminal device.
