Dynamic QoS Adjustment via Device-Initiated Service Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communications networks lack accurate predictive models for IP traffic, leading to network inflexibility and unpredictable service quality, with existing quality management approaches either reserving idle capacity or failing to guarantee quality of service (QoS), resulting in delayed data sessions and service interruptions.
Innovation Solution
Implementing a system that allows devices to dynamically request QoS changes based on current usage and features, shifting the logic for monitoring and resource allocation from network elements to devices, enabling instant and flexible service adjustments without increasing network burden, through an Instant Policy and Charging Rules Function (IPCRF) that processes service change requests and allocates resources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time division multiplexing (TDM) is used to maintain quality of service, then QoS for individual users is maintained, but network inflexibility and unused idle capacity occur
Solution Approach 1:
The patent implements dynamic QoS adjustment by allowing devices to send service change requests that modify quality parameters in real-time based on current network conditions and application needs, transitioning from static TDM time-slot allocation to dynamic resource adjustment
Solution Approach 2:
The system changes QoS parameters dynamically by processing service change requests that modify bandwidth, priority, and other quality parameters according to current network conditions and application requirements, rather than maintaining fixed parameters
2Ease of operation
If best-effort transmission is used to achieve flexible data management, then all data sessions can access the network instantly, but quality of service delivery cannot be guaranteed
Solution Approach 1:
The patent implements dynamic QoS adjustment by allowing devices to send service change requests that modify quality parameters in real-time based on current network conditions and application needs, transitioning from static TDM time-slot allocation to dynamic resource adjustment
Solution Approach 2:
The system uses feedback mechanisms where devices monitor their own service quality and send service change requests when QoS thresholds are not met, creating a closed-loop control system that continuously adjusts resources based on actual performance
3Reliability
If network elements monitor and control service changes, then centralized QoS management is maintained, but network burden and complexity increase
Solution Approach 1:
The patent enables devices to autonomously monitor their own service quality and generate service change requests based on predefined QoS thresholds, reducing the need for continuous network element intervention and simplifying network control architecture

AI summary
Systems and methods for providing differentiated user service options on communications networks are disclosed. Devices can be configured to generate service change requests, and to transmit the service change requests to a network node. The service change request can be routed to a node that determines if the service change request should be granted. The device and network can begin operation in accordance with the service change request almost instantly since no negotiation is required between the device and the network. Methods and computer-readable media embodying methods for providing differentiated user service options, are also disclosed.
