ABSTRACT:
A data communication service according to the present invention is capable of tracking a connection status of a wireless device on a wireless network, receiving electronic messages from one or more senders, waiting a period of time for the wireless device to move in contact with the wireless network after the wireless device has moved out of contact with the wireless network, and, maintaining a continuous virtual connection for the period of time. The data communication service is also capable of sending information describing parameters of the connection status to one or more senders, storing messages sent to the wireless device during the period of virtual connection and transmitting the stored messages to the wireless device after the wireless device moves back in contact with the wireless network.
