PDU Set QoS Coordination for Uplink RAN and Core Network Handling

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing technologies do not adequately address how a terminal, Radio Access Network (RAN), and core network cooperate to determine whether and how to perform Protocol Data Unit Set (PDU Set) based handling, particularly in uplink scenarios.

Innovation Solution

The proposed solution involves communication devices exchanging requests and capability information to determine support for PDU Set based handling, with the core network and RAN making decisions based on these exchanges to apply or reject handling requests, and sending necessary PDU Set parameters to ensure appropriate handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If PDU Set based handling is implemented in uplink, then QoS handling capability is improved, but device complexity and coordination overhead increase

Engineering Contradiction:

ImproveQoS handling capabilityVSAvoidcoordination complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the PDU Set handling capability into separate indication fields for uplink and downlink directions. The terminal can independently indicate support for PDU Set based handling in uplink, downlink, or both directions, allowing granular control and reducing unnecessary coordination overhead for directions where the capability is not needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary capability indication during the initial connection setup or configuration phase. The terminal sends capability information indicating PDU Set based handling support before actual data transmission begins, allowing the network to pre-configure appropriate QoS parameters and handling procedures, thereby reducing real-time coordination complexity.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If capability information exchange is performed, then coordination efficiency is improved, but signaling overhead increases

Engineering Contradiction:

Improvecoordination efficiencyVSAvoidsignaling overhead

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent merges the PDU Set capability indication with existing terminal capability information exchange procedures. The capability information is embedded within standard signaling messages already used for terminal configuration, thereby improving coordination efficiency without significantly increasing overall signaling overhead.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent designs the capability indication mechanism to serve multiple functions: it indicates PDU Set based handling support, enables network-side configuration decisions, and facilitates appropriate QoS parameter selection. This multi-functionality reduces the need for separate dedicated signaling messages.

Inventive Principle:

Principle #6Universality (Multi-functionality)
