QoS Framework Weight Factor for Wireless Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current QoS frameworks for IP wireless access networks do not effectively support variable bit rate applications, as they lack the ability to utilize both average bit rate (ABR) and maximum bit rate (MBR) values, leading to inefficiencies in differentiating subscriber traffic priorities, especially during network congestion.
Innovation Solution
Introducing a configurable weight factor into the QoS framework that incorporates ABR and MBR values, allowing for dynamic bandwidth allocation and traffic management based on QoS settings, enabling better differentiation of subscriber traffic and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current QoS frameworks are used for rate limiting, then subscriber differentiation is provided, but effectiveness deteriorates during network congestion
Solution Approach 1:
The patent changes the QoS parameters from traditional single rate limiting to dual rate limiting with ABR and MBR values, enabling more effective traffic management during congestion by considering both average and maximum bit rates simultaneously
Solution Approach 2:
The patent introduces dynamic bandwidth allocation based on QoS settings and weight factors, allowing the network to adaptively adjust resource distribution in real-time during congestion rather than using static rate limits
2Adaptability or versatility
If traditional QoS frameworks are used, then basic rate limiting is provided, but support for variable bit rate applications deteriorates
Solution Approach 1:
The patent makes the QoS framework universal by enabling it to handle both fixed rate and variable bit rate applications through the incorporation of both ABR and MBR parameters, allowing a single framework to serve multiple application types
Solution Approach 2:
The patent extends the QoS parameter set to include both ABR and MBR values, transforming the framework from one that only supports basic rate limiting to one that can accommodate variable bit rate applications while maintaining reliability
3Ease of operation
If bandwidth is allocated without weight factors, then simple allocation is achieved, but traffic prioritization and fairness deteriorate
Solution Approach 1:
The patent applies local quality by introducing weight factors specific to different QoS classes, allowing each class to receive tailored bandwidth allocation based on its priority and requirements rather than uniform treatment
Solution Approach 2:
The patent implements dynamic bandwidth allocation using weight factors that can adjust resource distribution in real-time based on current network conditions and QoS settings, replacing static simple allocation with adaptive prioritization

AI summary
A base station for an Internet protocol (IP) wireless access network receives a policy for subscriber traffic over a particular bearer, where the policy includes a particular quality-of-service control indicator (QCI) value, and an average bit rate (ABR) value, a maximum bit rate (MBR) value, and a weight factor value associated with the QCI value. The base station detects network congestion associated with the IP wireless access network and applies, to the subscriber traffic over a particular bearer, the weight factor, the ABR value, and/or the MBR value to manage the network congestion.
