Description

CROSS REFERENCES TO RELATED APPLICATIONS This application is a continuation of copending U.S. application Ser. No. 17/628,562, filed Jan. 20, 2022, which is incorporated herein by reference in its entirety, which in turn is a national stage application based on International Application No. PCT/KR2020/003520, filed Mar. 13, 2020, which claims priority from Korean Application No. 10-2019-0097272, filed Aug. 9, 2019. TECHNICAL FIELD The present disclosure is generally related to a communication connection method for a continuous blood glucose monitoring system, in more detail, a communication connection method for a continuous blood glucose monitoring system for communication connection between a sensor transmitter of the continuous blood glucose monitoring system continuously measuring blood glucose and a communication terminal receiving data measured by the sensor transmitter. BACKGROUND In order to manage diabetes, the continuous measurement of blood glucose is required, and therefore the demand for devices related to blood glucose measurement is steadily increasing. It has been confirmed through various studies that the occurrence of complications of diabetes is significantly reduced when diabetic patients strictly control blood glucose. Accordingly, it is very important for diabetics to regularly measure blood glucose in order to manage blood glucose. In general, a finger prick method is mainly used for blood glucose management by diabetic patients and this type of blood sugar collection system helps the diabetic patients in managing their blood glucose, but it is difficult to accurately identify the blood glucose levels which are being frequently changed because it shows only the result at the time of the measurement. In addition, the finger prick type blood glucose device needs to collect blood several times from time to time even in a day, so diabetics have a burden on blood collection. Diabetics patients generally experience hyperglycemia and hypoglycemia, and an emergency may occur in the hypoglycemic conditions. The patients may become unconscious or die if a hypoglycemic condition lasts for an extended period of time without the supply of sugar. Accordingly, rapid discovery of the hypoglycemic condition is critically important for diabetics. However, blood-collecting type glucose monitoring devices intermittently measuring glucose have limited ability to accurately measure blood glucose levels. To overcome such a drawback, continuous glucose monitoring systems (CGMSs) inserted into the human body to measure a blood glucose level every few minutes have been developed, and therefore easily perform the management of diabetics and responses to an emergency situation. A continuous blood glucose monitoring system comprises a sensor transmitter attached to human body of a user, extracting body fluid, and measuring blood glucose, and a communication terminal displaying a received blood glucose level. The sensor transmitter generates blood glucose information by measuring the blood glucose of the user for a certain period, for example, around fifteen (15) days, in a state that the sensor transmitter is inserted into the human body. The sensor transmitter periodically generates the blood glucose information, and the communication terminal periodically receives the blood glucose information and outputs the received blood glucose information so that the user can check the blood glucose information. However, if the user deletes communication registration information of between the sensor transmitter and the communication terminal from the communication terminal or deletes a program or application installed at the communication terminal while using the continuous blood glucose monitoring system, the communication between the sensor transmitter and the communication terminal may be disconnected. In this case, the communication between the sensor transmitter and the communication terminal needs to be reconnected. In this case, the sensor transmitter has a limited usable time period, and it is necessary to strictly limit the reuse of a sensor transmitter of which usable time period is expired, or to block the reuse of a sensor transmitter used by another user. Accordingly, when the communication connection between the sensor transmitter and the communication terminal is disconnected and then reconnected, it is necessary to check whether the sensor transmitter to be reconnected is a sensor transmitter of which usable time period is expired or a sensor transmitter used by another user. Accordingly, it is necessary to block the reuse of a sensor transmitter of which usable time period is expired or a sensor transmitter used by another user. Additionally, if an existing user wants to continue to use a sensor transmitter of which usable time period is left, a novel communication connection method between the sensor transmitter and the communication terminal in which the communication connection between the sensor trans
