Packet Loss Feedback for XR Traffic Statistics Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Extended Reality (XR) services, packet loss handling leads to inconsistencies in traffic statistics between the core network and terminal sides due to the discard of P frames associated with undeliverable I frames, causing resource waste and statistical discrepancies.
Innovation Solution
A packet loss handling method involving nodes exchanging packet discard or loss-related information through various communication protocols (CP, UP, GTP-U) to synchronize traffic and cost statistics, using bearer IDs, timestamps, and packet loss rates to manage packet handling and avoid inconsistencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If P frames associated with undeliverable I frames are discarded to avoid resource waste, then wireless interface resource efficiency is improved, but traffic statistics consistency between core network and terminal is deteriorated
Solution Approach 1:
The patent implements feedback mechanisms where the terminal reports packet loss information and the core network adjusts its packet discarding behavior accordingly. This allows the system to maintain resource efficiency while compensating for discarded packets through feedback-based statistics alignment.
Solution Approach 2:
The patent changes parameters such as packet discarding thresholds, reporting triggers, and statistics calculation methods to balance resource efficiency with statistical accuracy. By dynamically adjusting these parameters, the system can adapt to different network conditions while maintaining consistency.
2Loss of energy
If packet discarding is performed to handle packet loss, then resource waste is reduced, but statistical accuracy between network sides is deteriorated
Solution Approach 1:
The patent introduces intermediary mechanisms such as packet loss reporting messages and statistics adjustment functions that mediate between the packet discarding action and the statistics measurement. These intermediaries ensure that discarded packets are accounted for in statistics while still benefiting from resource savings.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring packet loss handling parameters, reporting thresholds, and statistics adjustment rules before packet discarding occurs. This allows the system to prepare compensation mechanisms in advance, ensuring statistical accuracy is maintained even when packets are discarded.
