WiFi Access Point QoS Tunnel Prioritization for Mobile Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communication methods over public mobile networks using WiFi access points often prioritize non-time-critical services equally with time-critical services, leading to reduced bandwidth and unacceptable quality of service for critical applications like voice or video streaming due to shared resource allocation.
Innovation Solution
Establishing a secure communication tunnel between a mobile entity and the internet via a WiFi access point with a public mobile network backhaul, where the priority for data communication is set based on content information, utilizing Quality of Service (QoS) parameters to ensure timely and reliable delivery of time-critical services by prioritizing their communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all data communications are handled with best effort mode on the public mobile backhaul, then resource sharing is simplified and device complexity is reduced, but time-critical services receive insufficient priority leading to unacceptable quality of service
Solution Approach 1:
The system performs preliminary classification of data communications into time-critical and non-time-critical categories before transmission. The WiFi access point examines communication requests and assigns appropriate priority levels in advance, ensuring that time-critical services are pre-identified and prepared for prioritized handling through the mobile network backhaul.
Solution Approach 2:
The patent implements local quality differentiation at the WiFi access point level by applying different QoS treatment to different types of communications. Time-critical services receive enhanced local processing and prioritization at the access point, while non-time-critical services use standard best-effort handling, creating localized quality differentiation without requiring complex end-to-end QoS management.
2Productivity
If multiple mobile entities share the same mobile network backhaul queue, then network resource utilization is improved, but bandwidth available to individual entities is reduced leading to noticeable performance degradation
Solution Approach 1:
The patent segments the shared backhaul queue into multiple priority queues at the WiFi access point level. Time-critical communications are segmented into a separate high-priority queue, while non-time-critical communications remain in the standard queue. This segmentation allows the system to maintain high overall resource utilization while ensuring that time-critical services receive dedicated bandwidth allocation.
Solution Approach 2:
The system changes the priority parameter of specific data communications based on their time-critical nature. By dynamically adjusting the priority parameter for time-critical services, the patent ensures that these communications receive higher bandwidth allocation and faster transmission speeds while maintaining efficient utilization of the shared backhaul resources.
3Adaptability or versatility
If the WiFi access point uses local QoS rules for queue management, then service differentiation within the WiFi network is improved, but the public mobile backhaul still treats all traffic equally resulting in loss of priority information
Solution Approach 1:
The WiFi access point acts as an intermediary that translates local QoS decisions into standardized priority markings that can be recognized by the mobile network backhaul. The access point applies QoS parameters to outgoing traffic and uses protocol mechanisms to preserve priority information through the backhaul, preventing information loss by serving as an active mediator between the WiFi network and the mobile network.
Solution Approach 2:
The patent implements a universal QoS marking mechanism that works across both WiFi and mobile network domains. By using standardized priority indicators that are recognized by both networks, the system achieves multi-functionality where the same priority marking system serves both local WiFi queue management and remote mobile network resource allocation, preventing priority information loss.
