Access Network QoS Signaling for Controlled Packet Discarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G network faces challenges in managing high bandwidth and low latency requirements for extended reality (XR) services, leading to inefficient data transmission and inaccurate charging due to unsolicited packet discarding during network congestion.
Innovation Solution
An information processing method involving an access network function node that sends first indication information through a control plane function to trigger packet discarding events based on QoS handling, allowing network functions to determine and manage packet discarding accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet discarding is performed during network congestion to maintain QoS, then network efficiency and QoS management are improved, but inaccurate charging results occur due to unsolicited packet discarding
Solution Approach 1:
The patent applies preliminary action by establishing packet discarding filters and QoS rules in advance through the SMF before congestion occurs. The UPF is pre-configured with filtering criteria that automatically trigger packet discarding only when specific congestion conditions are met, preventing unsolicited discarding and ensuring accurate charging while maintaining QoS reliability.
2Productivity
If high bandwidth is allocated for XR services to meet service requirements, then service quality is improved, but network congestion increases leading to more packet discarding
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting QoS parameters including bandwidth allocation, packet discarding thresholds, and filtering criteria based on real-time network conditions. The SMF monitors network status and modifies these parameters to optimize bandwidth utilization for XR services while preventing excessive congestion that would trigger unwanted packet discarding.
3Reliability
If strict QoS requirements are enforced for low latency XR services, then service performance is improved, but network flexibility decreases making congestion management difficult
Solution Approach 1:
The patent applies dynamics by implementing a flexible QoS management system where the SMF continuously monitors network conditions and dynamically adjusts packet discarding policies, filtering rules, and QoS parameters. This allows the system to maintain strict latency requirements for XR services under normal conditions while adapting congestion management strategies when network conditions change, balancing reliability with adaptability.
