Subservice Flow Management for 5G QoE Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoS-based approaches in wireless networks are inadequate for managing the diverse and dynamic traffic demands of applications like V2E and IoT, as they lack granular differentiation and adaptability to ensure optimal Quality of Experience (QoE).
Innovation Solution
Implementing an enforcement point that partitions user-plane flows into subservice flows, allowing for autonomous and adaptive definition of QoS and QoE parameters, enabling finer-grained service differentiation and dynamic management of radio buffers to meet specific application requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing QoS-based approaches are used to manage traffic, then network management is simplified, but granular differentiation and adaptability for diverse applications are insufficient
Solution Approach 1:
The patent segments user-plane flows into multiple subservice flows, each with distinct QoS and QoE parameters. This segmentation enables granular differentiation of traffic types (e.g., V2E, IoT, streaming) while maintaining manageable complexity through hierarchical organization of flow categories and parameter groups.
Solution Approach 2:
The enforcement point dynamically defines and adjusts QoS and QoE parameters based on real-time application requirements and network conditions. This dynamic adaptation allows the system to respond to diverse application needs without requiring static, pre-configured rules for every scenario.
2Productivity
If static QoS parameters are used for traffic flows, then configuration is simple, but real-time QoE optimization for dynamic traffic demands is inadequate
Solution Approach 1:
The system transitions from static QoS parameters to dynamic QoS and QoE parameters that are adjusted in real-time based on application performance requirements and network conditions. The enforcement point continuously monitors and reconfigures parameters to optimize traffic handling efficiency for diverse applications.
Solution Approach 2:
The patent changes the nature of QoS parameters from fixed static values to dynamic adjustable parameters including QoS parameters and QoE parameters. This parameter transformation enables real-time optimization of traffic flows while the enforcement point manages the complexity of parameter configuration and adjustment.
3Reliability
If fine-grained service differentiation is implemented, then QoE is improved, but system complexity increases
Solution Approach 1:
The enforcement point segments flows into categorized groups (e.g., V2E, IoT, streaming, gaming) with specific QoS and QoE parameter sets for each category. This segmentation provides fine-grained service differentiation for reliability while managing complexity through organized classification rather than individual configuration of every flow.
Solution Approach 2:
The patent adds the QoE dimension to traditional QoS management, creating a multi-dimensional parameter space that includes both QoS parameters (technical metrics) and QoE parameters (user experience metrics). This dimensional expansion enables comprehensive quality guarantee while the enforcement point manages the increased complexity through unified parameter handling.
Data Source
AI summary
Methods and apparatus, including computer program products, are provided for QoE/QoS management. In some example embodiments, there may be provided a method. The method may include detecting, by an enforcement point, an initiation of a session of an application; determining, by the enforcement point, whether a new subservice flow needs to be established to enable, for the initiated session, a quality of service differentiation and/or a quality of experience differentiation; sending, by the enforcement point, an indication to a radio to enable the radio to establish a radio buffer to handle the new subservice flow, when the new subservice flow needs to be established; sending, by the enforcement point, parameter information to the radio to enable the radio to configure at least one service parameter of the radio buffer; and forwarding, by the enforcement point, user-plane data associated with the session to the radio including a subservice flow identifier.
