  • Blood glucose monitoring system having wireless communication module to which time synchronization method is applied
    Patent number: 9143250
    Abstract: The present disclosure relates to a blood sugar meter system with a wireless communication module, and more particularly, to a time synchronization method between a blood sugar meter system with a wireless communication module synchronized with a cellular network such as a global system for mobile communication (GSM)/code division multiple access (CDMA) network and the cellular network. The present invention provides a blood sugar meter system with a wireless communication module applying a time synchronization scheme including: a global system for mobile communication (GSM)/code division multiple access (CDMA) network transmitting network identity and time zone (NITZ) information; and a blood sugar meter metering user's blood sugar data, wherein the blood sugar meter synchronizes a network time according to the NITZ information with an internal time of the metered data and transmits the metered blood sugar data to a server connected to the GSM/CDMA network.
