CGM Packet Generation Identifiers for Missing Data Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional continuous glucose monitoring systems experience communication disconnections between sensor transmitters and communication terminals, leading to loss of biometric information and inability to continuously monitor blood glucose levels.
Innovation Solution
A method is introduced where transmission packets include generation identifiers, allowing for precise identification and retrieval of missing packets by comparing packet generation identifiers and total counts between the sensor transmitter and communication terminal, without requiring completion messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional continuous glucose monitoring systems transmit biometric information without generation identifiers, then the transmission process is simpler, but communication disconnections cause loss of biometric information
Solution Approach 1:
The transmission packet is segmented into distinct fields including generation identifier, biometric information, and timestamp. This segmentation allows the receiver to independently verify and reconstruct data even when communication is interrupted, resolving the contradiction between reliability and complexity by organizing complexity into manageable segments.
Solution Approach 2:
The generation identifier is preliminarily assigned to each transmission packet before transmission occurs. This preliminary action enables the receiver to detect missing packets and request retransmission without requiring complex real-time verification protocols, thereby improving reliability while maintaining relatively simple device complexity.
2Loss of information
If the system requires completion messages for each transmission packet, then data integrity can be verified, but the communication overhead and time increase
Solution Approach 1:
The transmission packet structure enables self-verification through embedded generation identifiers and timestamps. The receiver can independently determine data completeness without requiring explicit completion messages from the transmitter, thus reducing communication overhead and time while maintaining data integrity.
Solution Approach 2:
The system implements selective feedback where completion messages are only transmitted when actual data loss is detected through generation identifier verification. This reduces unnecessary communication overhead compared to requiring completion messages for every packet, resolving the contradiction between information integrity and communication time.
3Ease of operation
If the system uses simple transmission packets without generation identifiers, then the transmission protocol is simpler, but the ability to detect and retrieve missing packets is reduced
Solution Approach 1:
The generation identifier acts as a unique identifier that allows the receiver to distinguish between different transmission packets and detect missing ones. This simple addition to the packet structure provides robust missing packet detection without significantly complicating the transmission protocol, effectively resolving the contradiction between ease of operation and reliability.

AI summary
The present disclosure relates to a method for transmitting or receiving biometric information in a continuous glucose monitoring system and, more specifically, to a method for transmitting or receiving biometric information, in which: when a sensor transmitter generates a transmission packet, the transmission packet is generated to include a generation identifier for identifying the transmission packet or biometric information according to a generation order of the transmission packet or the biometric information, and therefore the biometric information may be transmitted or received without a loss thereof via the generation identifier; and a transmission packet or biometric information, which a communication terminal has failed to receive, is correctly determined on the basis of a packet generation identifier or a total number of transmission packets, so that only biometric information or a transmission packet, which has failed to be received between the sensor transmitter and the communication terminal, may be transmitted or received in a distinguished manner.
