5G PDU Set Processing for Selective Delivery Within Delay Budgets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing consistency processing method for protocol data units (PDU) sets in 5G networks results in irrational resource waste and inefficiency, as the entire PDU set is discarded upon loss of a single PDU, despite the application layer's capability to recover partial information and the successful transmission of other PDUs.
Innovation Solution
A method and apparatus that determine the successful transmission of a PDU set within a defined delay budget, allowing for selective handling of PDUs and PDU sets based on loss rates and end markers, thereby optimizing resource utilization and reducing unnecessary discarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the consistency processing method is applied to PDU sets, then the transmission reliability is improved, but the resource utilization deteriorates due to discarding successfully transmitted PDUs
Solution Approach 1:
The patent segments the PDU set processing into individual PDU-level evaluation and set-level decision making. Instead of treating the PDU set as an indivisible unit, the system evaluates each PDU's transmission status independently and makes granular decisions about which PDUs to deliver to the application layer, thereby avoiding the waste of successfully transmitted PDUs while maintaining reliability through selective delivery
Solution Approach 2:
The patent changes the processing parameter from binary set-level success/failure to continuous PDU-level transmission status evaluation. By introducing parameters such as individual PDU reception status, timing information, and configurable thresholds, the system transforms the rigid consistency processing into a flexible, parameter-driven decision process that optimizes both reliability and resource utilization
2Stability of the object's composition
If the entire PDU set is discarded upon loss of a single PDU, then the data consistency is improved, but the productivity deteriorates due to unnecessary discarding
Solution Approach 1:
The patent applies partial action by delivering only the successfully transmitted PDUs to the application layer rather than requiring complete PDU set delivery. The system performs just enough action to maintain acceptable data consistency by evaluating each PDU individually and making selective delivery decisions, thereby improving productivity without completely sacrificing data consistency
Solution Approach 2:
The patent introduces dynamic decision-making that adapts to actual transmission conditions. Instead of static all-or-nothing discarding, the system dynamically evaluates PDU transmission status, timing, and configurable parameters to make real-time decisions about which PDUs to deliver, thereby optimizing productivity while maintaining appropriate data consistency based on actual network conditions
3Loss of information
If the application layer recovers information from remaining PDUs, then the loss of information is reduced, but the measurement precision deteriorates due to incomplete data
Solution Approach 1:
The patent implements feedback mechanisms where the network function monitors PDU transmission status and provides information to the application layer about which PDUs were successfully delivered. This feedback enables the application layer to make informed decisions about information recovery and to understand the completeness of received data, thereby balancing information recovery with awareness of data completeness limitations
