End-to-End QoS Coordination Across UAS PDU Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in ensuring end-to-end Quality of Service (QoS) fulfillment for Command-and-Control (C2) communication in Unmanned Aerial System (UAS) scenarios, particularly in dynamic network environments where multiple PDU sessions correspond to a single end-to-end application session, lacking mechanisms for linking and dynamically adapting QoS across these sessions.
Innovation Solution
A system and method for managing end-to-end QoS in UAS communication by configuring and adapting QoS parameters across multiple PDU sessions, involving a UAE server and SEAL server to ensure consistent QoS across the UAV and UAV controller communication, utilizing network functions like SMF and UTM to monitor and adjust QoS parameters based on dynamic changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple PDU sessions are used for end-to-end application session in UAS communication, then network flexibility and connectivity options are improved, but QoS management and fulfillment across sessions become complex and difficult to coordinate
Solution Approach 1:
The patent merges QoS management across multiple PDU sessions by establishing a mapping relationship between sessions corresponding to the same end-to-end application. The system combines QoS parameters from multiple sessions and applies joint adaptation, transforming independent session management into a coordinated unified management approach.
Solution Approach 2:
The patent introduces a QoS management function as an intermediary entity that coordinates between multiple PDU sessions. This mediator establishes mappings between sessions, monitors QoS parameters across sessions, and triggers coordinated adaptations, simplifying the complexity of direct multi-session management.
2Reliability
If QoS parameters are dynamically adapted in response to network conditions, then QoS fulfillment reliability is improved, but the complexity of monitoring and adjusting parameters across multiple sessions increases
Solution Approach 1:
The patent implements feedback mechanisms where QoS parameters are continuously monitored in multiple PDU sessions, and adaptation decisions are made based on observed QoS changes. When QoS degradation is detected in one session, the system triggers coordinated adaptation across mapped sessions to maintain end-to-end QoS fulfillment.
Solution Approach 2:
The patent establishes mapping relationships between PDU sessions in advance, before QoS issues arise. This preliminary configuration enables the system to quickly respond to QoS changes by pre-defining which sessions are related and how they should be coordinated, reducing the complexity of real-time decision-making.
3Ease of operation
If QoS parameters are configured for each PDU session independently, then session configuration simplicity is improved, but end-to-end QoS consistency across multiple sessions deteriorates
Solution Approach 1:
The patent merges independent session configurations by establishing mapping relationships between PDU sessions that serve the same end-to-end application. While each session can be configured independently initially, the mapping mechanism combines their QoS management, ensuring that adaptations in one session are coordinated with others to maintain end-to-end consistency.

AI summary
Apparatuses, methods, and systems are disclosed for end-to-end QoS fulfillment. One apparatus includes an application interface that receives a request to manage the QoS of an end-to-end application session. Here, the end-to-end application session comprises a first session of a first UE connected to a first network and a second session of a second UE connected to a second network. The processor configures a first QoS parameter for the first session of the first UE and a second QoS parameter for the second session of the second UE and receives a trigger event related to the QoS change of the second QoS parameter. The processor determines a third QoS parameter for the first session of the first UE based on the QoS change of the second QoS parameter and communicates the third QoS parameter to the first network.
