QoS Description Information Determination via Network Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communications networks rely on preset quality of service (QoS) mechanisms that use subjective assumptions or fixed QoS information, which can be inaccurate and fail to ensure quality of service requirements, particularly in determining packet loss rate or latency.
Innovation Solution
A method and apparatus for determining QoS description information by receiving and processing feedback from network elements, allowing for dynamic allocation of radio resources and quality of service policies tailored to specific service requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed QoS information or subjective assumptions are used to control and manage different types of services, then the QoS mechanism can be implemented with simple preset rules, but the QoS information may be inaccurate or not applicable to specific network elements, failing to ensure service quality
Solution Approach 1:
The patent implements a feedback mechanism where network elements (base stations, core network elements) report their actual QoS capabilities and status to the network manager. The network manager uses this feedback information to dynamically adjust and determine accurate QoS description information that reflects real network conditions, rather than relying on fixed or assumed values. This closed-loop feedback system ensures QoS information accuracy while maintaining service quality.
Solution Approach 2:
Network elements autonomously determine their own QoS capabilities and report them to the network manager. Each network element serves itself by evaluating its own performance characteristics (packet loss rate, latency, throughput) and providing this self-assessed information to the central management system, eliminating the need for external measurement or assumption about network element capabilities.
2Adaptability or versatility
If fixed QoS information is used for all services, then the QoS mechanism is easy to implement with uniform rules, but it cannot adapt to different network elements and service requirements, reducing system flexibility
Solution Approach 1:
The patent segments QoS management into multiple components: network element capability reporting, network manager processing, and service-specific QoS determination. Each network element independently reports its capabilities, the network manager segments and analyzes this information by service type and network element, and generates customized QoS descriptions for each service-network element pair. This segmentation enables adaptability while managing complexity through modular processing.
Solution Approach 2:
The system transitions from static fixed QoS information to dynamic QoS determination. Network elements continuously report their current status, and the network manager dynamically adjusts QoS description information based on real-time network conditions, service requirements, and network element capabilities. This dynamic approach enables the system to adapt to changing conditions while using automated processes to manage complexity.
3Reliability
If subjective assumptions are used for QoS parameters like packet loss rate or latency, then the QoS mechanism can operate without detailed network element data, but the base station cannot determine whether service quality requirements are satisfied
Solution Approach 1:
The patent establishes a feedback loop where network elements report actual performance data (packet loss rate, latency, throughput) to the network manager. The network manager uses this feedback to determine accurate QoS description information that reflects real network conditions. This feedback mechanism eliminates information loss by ensuring the network manager has access to actual network element data needed for reliable service quality assurance.
Solution Approach 2:
The network manager acts as an intermediary between network elements and service quality requirements. It collects detailed network element data through standardized reporting interfaces, processes this information to determine appropriate QoS parameters, and uses this information to ensure service quality requirements are met. This intermediary role prevents information loss by centralizing data collection and processing.

AI summary
A method for determining quality of service (QoS) description information includes receiving at least one piece of QoS description information of a service. Each piece of the at least one piece of QoS description information includes parameter type information and a parameter requirement. The method also includes sending to a second core network element or an application function network element corresponding to the service, parameter type information and a parameter requirement in the at least one piece of QoS description information. The method further includes receiving from the second core network element or the application function network element, feedback information of the parameter type information and the parameter requirement. The method additionally includes determining at least one piece of target QoS description information in the at least one piece of QoS description information based on the feedback information.
