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.

8. A system according to claim 4, wherein the download content comprises a plurality of data packets, and wherein the processor of the terminal is capable of operating a download agent capable of receiving the plurality of data packets and receiving at least one information packet regarding at least one group of at least one data packet.

9. A system according to claim 8, wherein the download agent is capable of monitoring the received data packets to determine, based upon at least one information packet, if an interruption occurs in receiving the plurality of data packets such that the download agent receives less than the plurality of data packets of the download content, and wherein the download agent is capable of recovering the download content such that the download agent receives the plurality of data packets if an interruption occurs in receiving the plurality of data packets.

10. A method for downloading pushed content to a terminal, the method comprising:

receiving service loading content at a terminal, wherein the service loading content identifies download content and has a digital signature;

authenticating the service loading content based upon the digital signature; and

pulling the download content to the terminal when the service loading content is authenticated, wherein the service loading content is authenticated, and the download content is pulled, in response to receiving the service loading content and independent of interaction from a user of the terminal.

11. A method according to claim 10, wherein authenticating the service loading content comprises verifying the digital signature with a public key.

12. A method according to claim 11 further comprising:

digitally signing the service loading content with a private key associated with the public key; and

transmitting the service loading content to the terminal.

13. A method according to claim 10, wherein the service loading content identifies an origin server associated with the download content, and wherein pulling the download content comprises:

sending a request for the download content to the origin server when the service loading content is authenticated; and

receiving the download content at the terminal from the origin server in response to the request.

14. A method according to claim 13, wherein receiving the download content comprises receiving a download descriptor, and thereafter receiving the download content.

15. A method according to claim 14, wherein the download content comprises a plurality of data packets, and wherein receiving the download content further comprises:

determining if an interruption occurs in receiving the plurality of data packets such that the terminal receives less than the plurality of data packets of the download content; and

if an interruption occurs in receiving the plurality of data packets

recovering the download content such that the terminal receives the plurality of data packets.

16. A method according to claim 15, wherein recovering the download content comprises:
