APPARATUS AND METHODS FOR BANDWIDTH SAVING AND ON-DEMAND DATA DELIVERY FOR A MOBILE DEVICE

摘要

A method for reducing data bandwidth usage in wireless communication comprises receiving a request from the a mobile device to provide the an e-mail message; sending a request to the an e-mail server for delivery of the e-mail message; analyzing the e-mail message delivered from the e-mail server to determine if a size of the e-mail message is above a threshold value, and if not expanding the e-mail content to be above the threshold value; acknowledging to the mobile device the existence of the e-mail message and its respective size; and delivering to the mobile device header content of the e-mail content, thereby only a small fraction of the data corresponding to the e-mail message is actually delivered to the mobile device.
