US Patent 7627676 Communication control method, communication control apparatus and storage medium

Even if a communication is interrupted, a communication control module in a data terminal reestablish the communication without informing a communication module that the communication has been interrupted in a case where it is possible to reestablish the communication. The communication control module determines that the communication can be reestablished if the interruption is temporary, or the condition of a network is good. The communication module does not recognize the interruption of the communication if the communication can be reestablished. Therefore, when the communication circuit is reestablished, the data communication is restored retrospectively to the time of the interruption of the communication.
