QoS Control in Radio Communication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio networks, it is challenging to design bandwidth assurance and maximum delay for Network as a Service (NaaS) across the entire network due to changes in communication environments, and introducing Quality of Service (QoS) control from wired networks to radio networks is difficult, especially for mobile broadband services.
Innovation Solution
A communication device with a control unit that determines QoS provision based on obtained information and transmits this determination to other devices, enabling QoS control in radio communication, which includes a control unit, a transmitting unit, and a communication unit to apply QoS control based on the provided information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoS control from wired networks is introduced to radio networks, then QoS management capability is improved, but adaptability to changing communication environments deteriorates
Solution Approach 1:
The patent implements dynamic QoS control where the network node continuously monitors communication environment changes (such as signal quality, bandwidth availability, and interference levels) and adjusts QoS parameters in real-time. This allows the system to maintain wired-network-level QoS control accuracy while adapting to the dynamic nature of radio communication environments, resolving the contradiction between control precision and environmental adaptability.
Solution Approach 2:
The patent establishes a feedback mechanism where the network node receives QoS status information from user devices and environmental conditions, processes this information, and sends adjusted QoS control commands back to the devices. This closed-loop feedback system enables the network to maintain accurate QoS control while continuously adapting to changing radio conditions, effectively resolving the technical contradiction.
2Reliability
If bandwidth assurance and maximum delay are designed for entire network, then QoS guarantee is improved, but device complexity increases
Solution Approach 1:
The patent divides QoS control into multiple segments: network-level QoS policies defined by the network node, device-level QoS parameters configured on user devices, and dynamic adjustment mechanisms that operate independently at each level. This segmentation allows bandwidth assurance and delay guarantees to be implemented without requiring complex centralized design, as each segment can be configured and managed separately, reducing overall system complexity while maintaining QoS reliability.
Solution Approach 2:
The patent implements preliminary QoS configuration where the network node pre-defines QoS policies, bandwidth allocations, and delay parameters before actual communication occurs. User devices are pre-configured with QoS capabilities and parameters. When communication begins, these pre-established configurations are automatically applied, eliminating the need for complex real-time calculations and reducing device complexity while ensuring QoS guarantees are maintained.

AI summary
A communication device includes a control unit that obtains information related to Quality of Service (QoS) control and determines whether to transmit information indicating whether the QoS can be provided based on the information related to the QoS control; a transmitting unit that transmits the information indicating whether the QoS can be provided based on a result of the determination to another communication device; and a communication unit that executes radio communication to which the QoS control is applied, the QoS control being executed based on the information indicating whether the QoS can be provided.
