Abstract: The present disclosure relates to a method for transmitting and receiving non-received biometric information, and more specifically, to a method for transmitting and receiving biometric information, wherein, when there is biometric information that a communication terminal has not received from a sensor transmitter, the reception of the non-received biometric information is controlled differently by determining, from received adjacent biometric information, whether the domain to which the non-received biometric information belongs is a dangerous domain or a normal domain.

Abstract: The present disclosure relates to a method for transmitting or receiving biometric information between a sensor transmitter and a communication terminal in a continuous blood glucose measurement system and, more specifically, to a method for transmitting or receiving biometric information, wherein: it is not determined at every regular communication period whether biometric information has been successfully transmitted or received between a sensor transmitter and a communication terminal; it is determined whether unreceived biometric information exists only at a unreceived communication period relatively larger than the regular communication period; if unreceived biometric information exists, the unreceived biometric information is received; and it is accordingly possible to reduce computing loads required to determine at every regular communication period whether unreceived biometric information exists, and the waste of energy required to receive unreceived biometric information at every regular communicatio

Abstract: The present disclosure relates to a method for transmitting/receiving biometric information in a continuous glucose monitoring system, and more specifically, to a method for transmitting/receiving biometric information, in which, in each communication cycle, first, an identifier of the last transmit packet received by a communication terminal is transmitted to a sensor transmitter, and the sensor transmitter transmits, to the communication terminal, a transmit packet generated after the last transmit packet, and thus biometric information generated by the sensor transmitter may be transmitted without loss to the communication terminal.

Abstract: 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, ma

Abstract: The present disclosure relates to a communication connection method for a continuous glucose monitoring system. A communication connection method for a continuous glucose monitoring system according to an embodiment of the present disclosure may comprise: a step in which, in order to connect communication between a communication terminal and a sensor transmitter attached to a human body so as to continuously monitor biometric information of the human body, the communication terminal receives information of the sensor transmitter from the sensor transmitter; a step of determining, on the basis of the received information, whether the sensor transmitter is a new sensor transmitter or an already used sensor transmitter; and a step in which, when the sensor transmitter is an already used transmitter, communication connection is controlled on the basis of use information of the already used sensor transmitter.

Abstract: An apparatus for controlling operations of a continuous glucose monitoring system. When a continuous glucose monitoring system is located within a certain distance from a user terminal, power of a battery is supplied to the continuous glucose monitoring system through a power switch switched on by an enable signal generated by a near field communication module, thereby operating the continuous glucose monitoring system without user intervention. The near field communication module provides connection information to the user terminal, thereby automatically performing a pairing connection with the user terminal using the near field communication module and a bluetooth communication module. When the pairing connection with the user terminal is completed, an enable signal generated by the bluetooth communication module is provided to the power switch, thereby maintaining the pairing connection with the user terminal even when the user terminal is outside of range for near field communication.

Abstract: A terminal may include a memory to store first encryption information applied to the handheld terminal and second encryption information corresponding to a phone number of another party's terminal, and a control unit to encrypt a message using the first encryption information and the second encryption information stored in the memory, when transmitting the message to the other party's terminal.
