Apparatus and methods for bandwidth saving and on-demand data delivery for a mobile device
A method for reducing data bandwidth usage in wireless communication comprises receiving a request from 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.
1. A network component comprising:
an interface configured to receive traffic on a network path between an e-mail server and a mobile device;
a processing unit to process a request from the mobile device to the e-mail server, manipulate at least one of a text or an attached file of an e-mail message received from the e-mail server to expand a size of the e-mail message above a threshold value of the mobile device, and provide to the mobile device only preview information of the e-mail message.
2. The network component of claim 1 , wherein the preview information comprises header information from the e-mail message.
3. The network component of claim 1 , wherein the processing unit expands the text portion to be of a size that is larger than the threshold value when the text portion of the e-mail message is not above the threshold value, the threshold value determined by an e-mail application executed by the at least one mobile device.
4. The network component of claim 3 , wherein expanding the text portion is followed by compression of the expanded text of the e-mail message.
5. The network component of claim 4 , wherein the compression is at least a GZIP compression.
6. The network component of claim 3 , wherein expanding the text portion includes at least one of adding line breaks or adding space characters.
7. The network component of claim 1 , wherein the network component is at least one of a proxy server, a virtual private network (VPN) server, a traffic shaper, a router, or a network address translator (NAT).
8. A non-transitory computer-readable medium storing instructions configured to cause one or more processors to:
receive a request on an interface in a network path between an e-mail server and a mobile device;
manipulate at least one of a text or an attached file of an e-mail message received by the network component from the e-mail server to expand a size of the e-mail message above a threshold value of the mobile device, and
provide to the mobile device only preview information of the e-mail message.
9. The non-transitory computer-readable medium of claim 8 , wherein the preview information comprises header information from the e-mail message.
10. The non-transitory computer-readable medium of claim 8 , further storing instructions configured to cause the one or more processors to expand the text portion to be of a size that is larger than the threshold value when the text portion of the e-mail message is not above the threshold value, the threshold value determined by an e-mail application executed by the at least one mobile device.
11. The non-transitory computer-readable medium of claim 10 , wherein the expanding the text portion is followed by compression of the expanded text of the e-mail message.
12. The non-transitory computer-readable medium of claim 11 , wherein the compression is at least a GZIP compression.
13. The non-transitory computer-readable medium of claim 10 , wherein expanding the text portion includes at least one of adding line breaks or adding space characters.
14. The non-transitory computer-readable medium of claim 8 , wherein instructions are configured for execution on at least one of a proxy server, a virtual private network (VPN) server, a traffic shaper, a router, or a network address translator (NAT).
15. A method comprising:
receiving a request on an interface in a network path between an e-mail server and a mobile device;
manipulating at least one of a text or an attached file of an e-mail message received by the network component from the e-mail server to expand a size of the e-mail message above a threshold value of the mobile device, and
providing to the mobile device only preview information of the e-mail message.
16. The method of claim 15 , wherein the preview information comprises header information from the e-mail message.
17. The method of claim 15 , further comprising expanding the text portion to be of a size that is larger than the threshold value when the text portion of the e-mail message is not above the threshold value, the threshold value determined by an e-mail application executed by the at least one mobile device.
18. The method of claim 17 , wherein the expanding the text portion is followed by compression of the expanded text of the e-mail message.
19. The method of claim 18 , wherein the compression is at least a GZIP compression.
20. The method of claim 15 , wherein expanding the text portion includes at least one of adding line breaks or adding space characters.
