Solution Overview
Problem
Current techniques for scheduling uplink transmissions in 5G networks are unable to detect fixed wireless access (FWA) uplink congestion accurately, leading to resource consumption and poor user experience due to disrupted and delayed transmissions.
Innovation Solution
A congestion detection system that utilizes a packet probe to analyze uplink packet flows, grouping packets into bursts and calculating transfer speeds and delays to identify congestion, conserving resources and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current scheduling techniques are used to manage uplink transmissions, then the base station can maintain simple scheduling operations, but uplink congestion cannot be detected accurately leading to transmission disruptions and delays
Solution Approach 1:
A packet probe is introduced as an intermediary component between the base station and user equipment. The packet probe captures uplink packet flows and provides detailed congestion information to the base station, enabling accurate congestion detection without requiring the base station to implement complex detection algorithms itself. This mediator approach resolves the contradiction by achieving high measurement precision while keeping the base station's scheduling system relatively simple.
Solution Approach 2:
The system implements a feedback mechanism where the packet probe continuously monitors uplink transmissions and provides real-time congestion status information back to the base station. This feedback loop enables the base station to adapt its scheduling decisions based on actual congestion conditions, achieving accurate congestion detection through systematic information collection and response rather than through inherently complex detection mechanisms.
2Productivity
If the base station disrupts uplink transmissions during congestion to manage load, then network resource utilization can be maintained, but user experience deteriorates due to transmission disruptions and delays
Solution Approach 1:
The packet probe performs preliminary detection of congestion conditions before they severely impact user transmissions. By identifying congestion early through continuous monitoring of uplink packet flows, the system can take preventive scheduling actions that maintain network resource utilization while avoiding the need to disrupt already-established user transmissions, thus preserving user experience quality.
Solution Approach 2:
The system enables the network to self-regulate congestion through intelligent scheduling decisions based on packet probe data. Rather than disrupting transmissions, the scheduling system automatically adjusts resource allocation to accommodate congestion conditions while maintaining overall network productivity. This self-service approach allows the network to manage its own resource utilization without external intervention, maintaining both productivity and reliability.

AI summary
A device may receive, from a packet probe, an uplink packet flow provided to a base station by a user equipment, and may add bytes for packets of the uplink packet flow in each scheduling interval of multiple scheduling intervals. The device may group the packets into bursts based on the multiple scheduling intervals and based on adding the bytes for the packets, and may calculate a transfer speed of each of the bursts. The device may calculate a maximum transfer speed for the bursts based on the transfer speed of each of the bursts, and may calculate a congestion delay for each of the bursts based on the maximum transfer speed for the bursts. The device may perform one or more actions based on the congestion delay for each of the bursts.
