Abstract

A web service for pre-caching web content on a mobile device includes receiving a request from the mobile device for first web content, fetching the first web content, determining second web content to pre-fetch based upon the first web content, fetching the second web content, and causing the second web content to be stored in a content cache on the mobile device responsive to the request for the first web content. Pre-caching web content in this manner provides web content to the mobile device that the user of the mobile device is likely to access. Pre-caching of additional web content prior to receiving an explicit request improves web browsing performance of the mobile device.

Claims

1. A method at a mobile device, the method comprising:

receiving a web request message for requested web content;

checking a content cache on the mobile device for the requested web content;

if the requested web content is in the content cache, retrieving the requested web content from the content cache;

if the requested web content is not in the content cache, forwarding the web request message to a network proxy;

receiving and displaying the requested content from the network proxy;

receiving additional content related to the requested content, without any request from the mobile device, at the mobile device;

caching the requested content received at the mobile device; and

caching the additional content at the mobile device.

2. The method of claim 1, wherein the additional content is based on parsing of the requested content.

3. The method of claim 2, wherein the additional content includes content from all links in the requested content.

4. The method of claim 2, wherein the additional content is further based on usage patterns from the mobile device.

5. The method of claim 4, wherein the usage patterns includes historical preferences for links from requested web content.

6. The method of claim 4, wherein the usage patterns includes historical preferences for non-linked web content.

7. The method of claim 1, wherein the receiving the additional content is from a push server communicating with the network proxy.

8. A mobile device, comprising:

a processor;

a communications subsystem; and

memory,

wherein the mobile device is configured to;

receive a web request message for requested web content;

check a content cache in the memory on the mobile device for the requested web content;

if the requested web content is in the content cache, retrieve the requested web content from the content cache;

if the requested web content is not in the content cache, forward the web request message to a network proxy utilizing the communications subsystem;

receive and display the requested content from the network proxy;

receive additional content related to the requested content, without any request from the mobile device, at the mobile device;

cache the requested content received at the mobile device; and

cache the additional content at the mobile device.

9. The mobile device of claim 8, wherein the additional content is based on parsing of the requested content.

10. The mobile device of claim 9, wherein the additional content includes content from all links within the requested content.

11. The mobile device of claim 9, wherein the additional content is further based on usage patterns from the mobile device.

12. The mobile device of claim 11, wherein the usage patterns includes historical preferences for links from requested web content.

13. The mobile device of claim 11, wherein the usage patterns includes historical preferences for non-linked web content.

14. The mobile device of claim 8, wherein the receiving the additional content is from a push server communicating with the network proxy.

15. A non-transitory computer-readable medium comprising instructions in code which when loaded into a memory and executed by a processor of a mobile device cause the mobile device to:

receive a web request message for requested web content;

check a content cache in the memory on the mobile device for the requested web content;

if the requested web content is in the content cache, retrieve the requested web content from the content cache;

if the requested web content is not in the content cache, forward the web request message to a network proxy utilizing the communications subsystem;

receive and display the requested content from the network proxy;

receive additional content related to the requested content, without any request from the mobile device, at the mobile device;

cache the requested content received at the mobile device; and

cache the additional content at the mobile device.

16. The non-transitory computer-readable medium of claim 15, wherein the additional content is based on parsing of the requested content.

17. The non-transitory computer-readable medium of claim 16, wherein the additional content includes content from all links within the requested content.

18. The non-transitory computer-readable medium of claim 16, wherein the additional content is further based on usage patterns from the mobile device.

19. The non-transitory computer-readable medium of claim 18, wherein the usage patterns includes historical preferences for links from requested web content.

20. The non-transitory computer-readable medium of claim 15, wherein the usage patterns includes historical preferences for non-linked web content.
