CPE LAN Link Categorization for Device-Specific QoS Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customer premises equipment (CPE) fails to provide customized quality of service (QoS) management per application and device within a local area network (LAN), leading to sub-optimal performance due to treating all devices with the same QoS, despite varying requirements.
Innovation Solution
CPE determines device categories based on QoS needs, establishes separate LAN links with customized QoS management, and integrates with 5G network slices using user equipment route selection policies to optimize bandwidth allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If CPE treats all devices with the same QoS management, then device compatibility and simplicity are improved, but performance optimization and user experience deteriorate due to inability to meet varying QoS requirements of different applications and devices
Solution Approach 1:
The patent implements differentiated QoS management by device category, where the CPE identifies devices as belonging to specific categories (gaming, video streaming, general computing, etc.) and applies customized QoS parameters to each category. This allows the system to provide locally optimized quality of service tailored to the specific requirements of each device type while maintaining a unified management framework.
2Productivity
If CPE establishes separate LAN links with customized QoS per device, then application performance and user experience are improved, but system complexity and device management overhead increase
Solution Approach 1:
The patent segments devices into distinct categories based on their QoS requirements, such as gaming devices, video streaming devices, general computing devices, and IoT devices. Each category is assigned specific QoS parameters and policies. This segmentation approach simplifies management by grouping devices with similar requirements together, allowing the CPE to apply standardized QoS configurations to each segment rather than managing each device individually.
Solution Approach 2:
The patent dynamically adjusts QoS parameters such as bandwidth allocation, priority levels, and latency thresholds based on the identified device category and current network conditions. The system modifies these parameters in real-time to optimize performance for active applications while maintaining overall network stability, thereby managing complexity through automated parameter adaptation rather than static complex configurations.
3Stability of the object's composition
If CPE allocates bandwidth uniformly to all devices, then network stability and fairness are improved, but customized performance optimization for specific applications deteriorates
Solution Approach 1:
The patent implements dynamic bandwidth allocation that adapts to changing network conditions and application requirements. The system continuously monitors network traffic, device activity, and QoS metrics, then adjusts bandwidth allocation in real-time based on current priorities and demands. This dynamic approach maintains network stability through controlled adaptation while optimizing bandwidth utilization efficiency by allocating more resources to high-priority applications when needed.

AI summary
In some implementations, a customer premises equipment (CPE) may determine a category associated with a device in a local area network (LAN), wherein the category is based on a quality of service (QoS) requirement associated with the device. The CPE may establish a LAN link with the device based on the category. The CPE may receive a user equipment route selection policy (URSP) rule for a network slice associated with the category. The CPE may establish a wireless wide area network (WWAN) link to a network node based on the URSP rule, wherein the WWAN link is based on the network slice and a QoS flow identifier associated with the category.
