Abstract

A system is provided for downloading pushed content includes a terminal capable of receiving service loading content that identifies download content and has a digital signature. The terminal is capable of authenticating the service loading content based upon the digital signature, and if the service loading content is authenticated, pulling the download content to the terminal. In this regard, the terminal is capable of authenticating the service loading content, and pulling the download content, in response to receiving the service loading content and independent of interaction from a user of the terminal. The terminal can also be capable of determining if an interruption occurs in receiving the download content such that the terminal receives less than the entire download content. And if an interruption occurs, the terminal can be capable of recovering the download content such that the terminal receives the plurality of data packets.
