Abstract

The present disclosure relates to the field of communications, and discloses a method for page redirection and a WAP gateway, which reduces the time delay the terminal experiences when acquiring pages. In the present disclosure, the WAP gateway requests, when receiving a page request from a user terminal, a page requested by the user terminal from a service provider; and when a page returned by the service provider satisfies a page redirection criterion, the WAP gateway performs a page redirection, and returns the page obtained after the redirection to the user terminal. The page redirection criterion is that the page contains redirection serial status codes indicating that a redirection is needed, or that the page contains an “onenterforward” mark. The WAP gateway retains the “Cookie” information included in the page returned by the service provider.

Claims

1. In a Wireless Application Protocol (WAP) gateway, a method for page redirection, comprising:

requesting, from a service provider, a first page requested by a user terminal of the service provider;

identifying that the first page returned by the service provider meets a first page redirection criteria; and

based on the identified redirection criteria met, performing a page redirection.

2. The method for page redirection according to claim 1, wherein the performing page redirection further comprises:

obtaining a second page after identifying the redirection criteria is met, and

sending the second page to the user terminal.

3. The method for page redirection according to claim 2, wherein the first page redirection criterion is that the first page contains redirection serial status codes indicating that a redirection is needed.

4. The method for page redirection according to claim 2, wherein the first page redirection criterion is that the first page contains an “

onenterforward”

mark.

5. The method for page redirection according to claim 2, wherein the method further comprises:

retaining “

Cookie”

information included in the first page; and

requesting an acquired page from the service provider according to the retained “

Cookie”

information when the WAP gateway needs to request the acquired page from the service provider.

6. The method for page redirection according to claim 2, wherein the method further comprises:

determining that the second page contains relative URL information;

based on the determined relative URL information, changing the relative URL information in the second page into absolute URL information; and

returning the second page containing the absolute URL information to the user terminal.

7. The method for page redirection according to claim 1, wherein the performing page redirection further comprises:

subsequently determining that the page requested by the user terminal is a download page or a page configured to not need page redirection; and

based on the subsequent determination, directly sending the first page satisfying the first page redirection criterion to the user terminal.

8. The method for page redirection according to claim 7, wherein the process of determining whether the page requested by the user terminal is a download page or a page configured to not need the redirection is based on a suffix name of the page requested by the user terminal.

9. The method for page redirection according to claim 1, wherein the method further comprises:

subsequently determining that a second page requested for page redirection is a download page or a page configured to not need the redirection; and

based on the subsequent determination, sending the first page to the user terminal.

10. The method for page redirection according to claim 9, wherein the determining that the second page is a download page or a page configured to not need the redirection based on a Multimedia Internet Mail Extend type of the second page.

11. The method for page redirection according to claim 2, wherein the method further comprises:

determining that the first page contains a timer; and

upon expiration of a time limit of the timer, performing the page redirection.

12. The method for page redirection according to claim 2, wherein the method further comprises:

determining that the second page satisfies a second page redirection criterion; and

based on the determination that the second page satisfies a second page redirection criterion, continuously performing subsequent page redirection until a page obtained does not meet one or more page redirection criterion, and

sending the obtained page that does not meet one or more page redirection criterion to the user terminal.

13. A Wireless Application Protocol (WAP) gateway, comprising:

a requesting module, configured to request a page requested by a user terminal from a service provider when receiving a page request from the user terminal, and receive a first page returned by the service provider;

a first determining module, configured to determine whether the first page returned by the service provider satisfies a first page redirection criterion;

a redirecting module, configured to perform a page redirection when the first determining module determines that the first page returned by the service provider satisfies the first page redirection criterion; and

a sending module, configured to return a second page which is obtained after the redirection by the redirecting module to the user terminal.

14. The WAP gateway according to claim 13, wherein the first page redirection criterion is that the first page contains redirection serial status codes indicating that a redirection is needed.

15. The WAP gateway according to claim 13, wherein the first page redirection criterion is that the first page contains an “

onenterforward”

mark.

16. The WAP gateway according to claim 13, wherein:

the WAP gateway further comprises a storing module, configured to retain “

Cookie”

information included in the first page returned by the service provider; and

when the requesting module needs to request an acquired page from the service provider, the requesting module requests the acquired page from the service provider according to the “

Cookie”

information retained by the storing module.

17. The WAP gateway according to claim 13, wherein:

the WAP gateway further comprises a URL information changing module, configured to change a relative URL information into absolute URL information when the second page contains the relative URL information; and

the sending module returns the second page in which the URL information has been changed to the user terminal.

18. The WAP gateway according to claim 13, wherein the WAP gateway further comprises:

a second determining module, configured to determine whether a page requested by the user terminal is a download page or a page configured to not need the redirection;

the sending module is further configured to send the page satisfying the page redirection criterion to the user terminal;

wherein the second determining module determines whether the page requested by the user terminal is a download page or a page configured to not need a redirection when the first determining module determines that the first page satisfies the first page redirection criterion, and if the page requested by the user terminal is not a download page or a page configured to not need a redirection, the second determining module triggers the redirecting module to perform the page redirection; and

if the page requested by the user terminal is a download page or a page configured to not need a redirection, the second determining module triggers the sending module to send the page satisfying the page redirection criterion to the user terminal.

19. The WAP gateway according to claim 13, wherein the WAP gateway further comprises:

a second determining module, configured to determine whether a page requested by the user terminal is a download page or a page configured to not need the redirection;

the sending module is further configured to send the first page satisfying the first page redirection criterion to the user terminal;

wherein the second determining module determines whether the page requested by the user terminal is a download page or a page configured to not need a redirection after the redirecting module performs the redirection, and if the page requested by the user terminal is not a download page or a page configured to not need a redirection, the second determining module triggers the sending module to return the second page to the user terminal; and

if the page requested by the user terminal is a download page or a page configured to not need a redirection, the second determining module triggers the sending module to send the first page to the user terminal.
