If the predicted arrival time value does not exist, the second wait-listed user starts receiving a medical treatment. And then, the system confirms whether a predicted arrival time value of a next wait-listed user exists between a predicted consultation time added up from the second waited-listed user to the user prior to the next wait-listed user and a predicted consultation time added up from a user following the second waited-listed user to the user prior to the next wait-listed user, and if so, the system transmits a message for announcing a starting time to a cellular phone of the next wait-listed user.
