Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If network capacity is increased to meet growing digital networking demand, then user service capacity is improved, but service provider costs increase and profits are negatively impacted
Solution Approach 1:
The patent implements QoS parameter changes by dynamically adjusting bandwidth allocation, traffic prioritization levels, and service class parameters based on network conditions and user requirements. This allows the network to maintain adequate capacity for essential services while reducing resource allocation for non-critical traffic, thereby managing costs without completely eliminating capacity constraints
Solution Approach 2:
The patent applies local quality by providing differentiated service quality to different traffic types, users, or network segments. High-priority traffic receives enhanced bandwidth and quality guarantees, while lower-priority traffic operates with reduced resources. This selective quality enhancement allows the network to improve perceived service quality in critical areas without proportionally increasing overall network capacity and associated costs
2Quantity of substance
If bandwidth is allocated to high bandwidth applications and content, then user service consumption is improved, but overall network service experience degrades
Solution Approach 1:
The patent introduces QoS management mechanisms as intermediaries between high-bandwidth applications and the network infrastructure. These intermediaries enforce bandwidth limits, prioritize traffic flows, and ensure that high-bandwidth applications do not monopolize network resources. This mediation allows individual users to access high-bandwidth content while preventing overall network degradation through controlled resource allocation
Solution Approach 2:
The patent implements dynamic bandwidth allocation that adjusts resource distribution in real-time based on network conditions, user requirements, and application priorities. During peak demand periods, bandwidth to high-bandwidth applications is automatically constrained to preserve service quality for other users. This dynamic adjustment ensures that bandwidth allocation responds adaptively to changing conditions, preventing systematic degradation of overall network experience
3Reliability
If QoS policy coordination is implemented across network boundaries, then service quality consistency is improved, but system complexity increases
Solution Approach 1:
The patent implements universal QoS policy coordination mechanisms that can operate across diverse network types, protocols, and administrative domains through standardized interfaces and common policy frameworks. This multi-functional approach allows a single QoS coordination system to manage services across wireless networks, wireline networks, IP networks, and legacy systems, reducing the need for separate complexity-intensive systems for each network type while maintaining service quality consistency across all boundaries
Data Source
AI summary
There is provided a wireless communications device including a memory storing an application and one or more QoS traffic control policies, and a processor. The processor is configured to determine a first quality of service (QoS) request for a service usage activity over a wireless network to the application, the first Qos request reflecting one or more wireless data channel parameters to support the service usage activity. The processor is also configured to monitor the first Qos request generated for the service usage activity, and compare a level of QoS requested for the first QoS request with a level of appropriate wireless network Qos to verify that a QoS traffic control policy that is applicable to the first QoS request is correctly implemented. The processor is configured to route data traffic corresponding to the first QoS request through a channel supporting an appropriate QoS for the first QoS request.
