Dynamic QoS Parameter Adjustment for Video Streaming Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoS mechanisms in IP networks cannot flexibly adjust QoS parameters based on changing service features, leading to suboptimal resource allocation and user experience in services like video on demand, where download rates vary over time.
Innovation Solution
A service transmission control method and device that dynamically adjusts QoS parameters by receiving indication information about target service features, such as play duration and bit rate, from a service transmission device, and querying a pre-recorded table of mapping to determine corresponding QoS parameters, allowing for flexible resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed QoS parameter is set for a service type, then the QoS parameter is simple to configure and maintain, but it cannot adapt to changing service features such as varying download rates in video on demand services
Solution Approach 1:
The patent implements dynamic QoS parameter adjustment by establishing a correspondence relationship between service feature information (such as download rate requirements at different time periods) and QoS parameters. The system automatically adjusts QoS parameters based on real-time service feature changes, transforming the fixed QoS configuration into a dynamic adaptive mechanism that responds to varying service demands without requiring manual reconfiguration.
Solution Approach 2:
The patent changes QoS parameters based on service feature information. By establishing a mapping between service features (like download rate requirements at different time periods) and QoS parameters, the system dynamically modifies QoS values according to actual service needs. This allows the QoS parameters to evolve from static defaults to dynamic values that adapt to changing service conditions.
2Reliability
If an excessively high QoS parameter is set, then user experience is improved, but air interface resources are wasted
Solution Approach 1:
The patent dynamically adjusts QoS parameters based on actual service feature information. Instead of using a fixed high QoS value that guarantees user experience but wastes resources, the system modifies QoS parameters according to real-time service requirements. For example, when video download rate requirements change at different time periods, the QoS parameters are automatically adjusted to match these requirements, ensuring adequate user experience while avoiding unnecessary resource consumption.
Solution Approach 2:
The system establishes a feedback mechanism where service feature information (such as actual download rate requirements) is used to adjust QoS parameters. This feedback loop allows the network to monitor service characteristics and automatically modify QoS settings accordingly, preventing both under-provisioning (which would degrade user experience) and over-provisioning (which would waste resources).
3Productivity
If a fixed QoS parameter is used for the entire transmission process, then the configuration is simple, but it cannot flexibly adjust to different service feature requirements at different time periods
Solution Approach 1:
The patent transforms fixed QoS configuration into a dynamic adaptive system. By establishing a correspondence relationship between service feature information and QoS parameters, the system automatically adjusts QoS settings based on real-time service requirements. This dynamic mechanism improves resource allocation efficiency by matching QoS parameters to actual service needs at different time periods without requiring complex manual reconfiguration.
Solution Approach 2:
The system pre-establishes a correspondence relationship between service feature information and QoS parameters before service execution. This preliminary configuration allows the system to automatically determine appropriate QoS parameters when service features change, eliminating the need for manual reconfiguration while maintaining high resource allocation efficiency throughout the transmission process.
