Multi-Modal QoS Flow Synchronization With Selective PDU Discard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in handling multi-modal synchronization for data flows with different importance levels and synchronization requirements, leading to inefficient resource allocation and potential data loss due to failed synchronization deadlines.
Innovation Solution
Implement mechanisms for the base station to determine whether an application can still utilize data after synchronization failure by using Multi-Modal Service Integrated Handling Information (MMSIHI) to configure discarding behavior based on synchronization requirements and importance levels, allowing selective data discard or continuation of transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission continues without selective discarding, then data delivery completeness is improved, but network resource waste increases due to unnecessary transmissions of data that cannot meet synchronization requirements
Solution Approach 1:
The patent implements selective discarding of data packets that cannot meet multi-modal synchronization requirements. The base station determines whether to discard data based on synchronization failure detection and application-specific configurations, avoiding unnecessary transmissions of data that would not be useful to the application, thereby reducing network resource waste while maintaining delivery of valuable data
Solution Approach 2:
The patent establishes a feedback mechanism where the base station receives information from the application about synchronization requirements and uses this feedback to make intelligent decisions about data transmission and discarding. The application can indicate whether it can still utilize data after synchronization failure, allowing the base station to optimize transmission decisions based on real-time application state
2Productivity
If selective data discarding is implemented, then network resource efficiency is improved, but data loss increases for packets that could have been delivered
Solution Approach 1:
The patent applies different discarding strategies to different data packets based on their specific characteristics. The base station determines discarding decisions on a per-data basis, considering factors such as synchronization requirements, application preferences, and data importance. This localized approach ensures that only appropriate data packets are discarded while preserving those that can still be useful
Solution Approach 2:
The patent dynamically adjusts transmission parameters based on synchronization status and application feedback. The base station can change transmission behavior from aggressive discarding to conservative retention based on application-indicated preferences, allowing flexible adaptation to different application requirements and scenarios
3Measurement precision
If multi-modal synchronization requirements are strictly enforced, then synchronization accuracy is improved, but system complexity increases due to additional configuration and management overhead
Solution Approach 1:
The patent extracts synchronization requirement configurations from the application layer and provides them to the base station as explicit parameters. This allows the base station to make informed transmission decisions without the application needing to implement complex synchronization logic, effectively moving the complexity management to the network side where it can be handled more efficiently
Solution Approach 2:
The patent creates a universal mechanism that handles multiple types of multi-modal applications through a common framework. The base station uses a unified approach to determine synchronization failures and apply discarding decisions across different applications, reducing the need for application-specific complex logic while maintaining support for diverse multi-modal scenarios

AI summary
Techniques are described herein for handling multi-modal synchronization. An example method can include processing first information relating to multi-modal synchronization between a first quality of service (QoS) flow and a second QoS flow. The method can further include processing second information indicating whether a packet data unit (PDU) discard is allowed based on a failure of the multi-modal synchronization. The method can further include generating, based on the first information and the second information, third information to configure a PDU discard behavior. The method can further include outputting the third information for transmission to a user equipment (UE).
