Receiving Window Configuration for Point-to-Multipoint Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, point-to-multipoint service data transmission often results in data loss due to incorrect configuration of receiving windows, leading to misinterpretation of received packets as duplicates or corrupted data.
Innovation Solution
Configuring the receiving entity to set the receiving window size to zero for point-to-multipoint services, ensuring all received data blocks are processed as new, thereby minimizing data loss and correcting sequence number handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a receiving window is configured for point-to-multipoint service data reception, then data can be received with sequence number validation, but data loss occurs when packets are misinterpreted as duplicates or corrupted data
Solution Approach 1:
The patent changes the receiving window size parameter from a non-zero value to zero specifically for point-to-multipoint service data reception. This parameter change disables sequence number validation that was causing packets to be misinterpreted as duplicates, thereby preventing data loss while maintaining the ability to receive all incoming packets correctly.
2Object-generated harmful factors
If sequence number validation is performed on received packets, then duplicate detection is enabled, but valid packets are incorrectly identified as duplicates in point-to-multipoint services
Solution Approach 1:
The patent applies local quality by making the receiving window size configuration service-specific. For point-to-multipoint services, the receiving window size is set to zero, disabling sequence number validation locally for this service type. This allows sequence number validation to remain active for other services where it is appropriate, while preventing false duplicate detection in point-to-multipoint contexts.
3Measurement precision
If the receiving window size is non-zero, then sequence number continuity can be verified, but data loss occurs due to misinterpretation of sequence numbers in point-to-multipoint services
Solution Approach 1:
The patent inverts the conventional approach by setting the receiving window size to zero instead of a non-zero value. This inversion disables sequence number continuity verification that was causing reliable data reception to fail, and instead enables all received packets to be accepted as valid, thereby improving data reception reliability for point-to-multipoint services.
