Abstract

In a network carrying a web page containing data, a method for dividing the web page into a maximum size chunk. In one aspect, the method comprises determining a chunk size limit, dividing the web page data into segments having a size no greater than said chunk size limit; and linking said chunks in sequence. In particular, the method finds applicability in a wireless network carrying content data via the network through at least one gateway, the gateway having a defined gateway limit. In a further aspect, the method includes: determining where the gateway limit falls in said content data; and parsing the content data into at least a first segment and at least a next segment of a size at or below the gateway limit at break points not falling within a word, universal resource locator, or element boundary.

Claims

1. In a network carrying a web page containing data, a method for dividing the web page into chunks, comprising:

determining a chunk size limit;

dividing the web page data into chunks having a size no greater than said chunk size limit; and

linking said chunks in sequence wherein the linking comprises inserting a link in one of the chunks comprising a link to another of the chunks.

2. The method of claim 1 wherein said step of linking, links chunks in a non-sequential manner.

3. The method of claim 1 wherein said step of linking, links chunks sequentially.

4. The method of claim 1 wherein said step of dividing comprises determining the point on the page where the chunk size limit is reached;

and

creating a table of universal resource locators to subsequent chunks of said page.

5. The method of claim 1 wherein said step of dividing comprises:

determining whether the chunk size limit falls on a word, universal resource locator, or element boundary, and establishing the break point at a position prior to said word, universal resource locator, or element boundary.

6. The method of claim 5 wherein a break point falling on a word is determined and positioned on a previous space, tab, or new line indicator.

7. The method of claim 5 wherein a break point falling on a universal resource locator is positioned on a previous tab, space, new line, or end of line indicator.

8. The method of claim 1 wherein said step of dividing comprises:

creating a table of universal resource locators (URLs) identifying each of said segments; and

fixing said URLs in said segments.

9. The method of claim 1 wherein said step of dividing assumes that meta-data in the web page has a fixed length.

10. The method of claim 9 wherein said meta-data comprises a universal resource locator.

11. In a wireless network carrying content data via the network through at least one gateway, the gateway having a defined gateway limit, a method for transmitting a quantity of content smaller than the gateway limit, comprising:

determining where the gateway limit falls in said content data; and

parsing the content data into at least a first segment and at least a next segment of a size at or below the gateway limit at break points not falling within a word, universal resource locator, or element boundary, wherein the segments are linked by inserting a link to another segment in a segment.

12. The method of claim 11 further including the step of:

linking said first segment and said at least next segment.

13. The method of claim 12 wherein said step of linking, links segments in a non-sequential manner.

14. The method of claim 12 wherein said step of linking, links segments sequentially.

15. The method of claim 11 wherein said step of parsing comprises creating a table of universal resource links to subsequent chunks of said page.

16. The method of claim 11 wherein said step of parsing comprises:

determining whether the gateway limit falls on a word, universal resource locator, or element boundary, and establishing the break point at a position prior to said word, universal resource locator, or element boundary.

17. The method of claim 16 wherein a break point falling on a word is determined and positioned on a previous space, tab, or new line indicator.

18. The method of claim 16 wherein a break point falling on a universal resource locator is positioned on the previous tab, space, new line, or end of line indicator.

19. The method of claim 11 wherein said step of parsing comprises:

creating a table of universal resource locators (URLs) identifying each of said segments; and

fixing said URLs in said segments.

20. The method of claim 11 wherein said step of parsing assumes that meta-data in the web page has a fixed length.
