Dynamic QoS Control in Communication Gateways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems lack the flexibility to dynamically modify quality of service (QoS) attributes and Allocation/Retention Priority (ARP) based on service requirements, leading to potential error situations due to reliance on subscription information and pre-configured settings.
Innovation Solution
A method and system that involves signaling control parameters from a node to a gateway, providing capability information, determining changed control parameters based on node capabilities, and informing the node to control communication sessions accordingly, enabling flexible modification of QoS and ARP attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional communication systems rely on subscription information and pre-configured settings to control communication sessions, then system operation is simplified and stable, but the system lacks flexibility to dynamically modify QoS attributes and ARP based on service requirements
Solution Approach 1:
The patent implements dynamic modification of control parameters (QoS attributes and ARP) during communication sessions. The gateway node can change these parameters based on service requirements rather than being fixed by subscription information, making the system adaptable while maintaining reliability through controlled modification processes
Solution Approach 2:
The patent enables changing of control parameters (QoS attributes and ARP) during session operation. The gateway node modifies these parameters dynamically based on service requirements, transitioning from static pre-configured settings to dynamic parameter adjustment, thereby improving adaptability while maintaining system reliability
2Productivity
If the system allows dynamic modification of control parameters based on service requirements, then service requirements are better met, but error situations may arise due to deviations from subscription information and pre-configured settings
Solution Approach 1:
The patent implements a feedback mechanism where the gateway node receives service requirements and dynamically adjusts control parameters accordingly. The system monitors service requirements and modifies QoS and ARP parameters in response, ensuring service requirements are met while maintaining system reliability through controlled feedback-driven adjustments
Solution Approach 2:
The gateway node acts as an intermediary between the subscription information system and the actual service delivery. It mediates between pre-configured settings and dynamic service requirements, allowing flexible parameter modification while maintaining system reliability by controlling the modification process

AI summary
In a communication system, a communication session can be arranged by means of a node and a gateway. Control parameters are commonly signaled for the communication session from the node to the gateway. In the method the gateway is provided with information about the capabilities of the node. A decision in made if at least one of the control parameters for the communication session needs to be changed. If so, the new value of the at least one control parameter is determined based on information of the capabilities of the node. The node is then informed about the changed value of the least one control parameter. The communication session can then be controlled based on the changed value of the at least one control parameter.
