WAP Gateway Page Redirection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional page redirection methods in mobile communications result in significant time delays due to multiple redirection interactions between user terminals and service providers, primarily caused by wireless interface transmission delays, which negatively impact user experience and efficiency.
Innovation Solution
A WAP gateway is configured to request and redirect pages on behalf of user terminals, determining if a page returned by the service provider requires redirection and performing the necessary page redirection, thereby reducing the burden on user terminals and wireless network bandwidth usage.

Engineering Contradiction Analysis
1Reliability
If the user terminal performs multiple page redirections to acquire the desired page, then the user terminal can acquire the final page, but the time delay from request initiation to page acquisition becomes very long
Solution Approach 1:
The WAP gateway acts as an intermediary between the user terminal and the service provider. When the gateway receives a page request, it proactively queries the service provider to determine whether redirection is needed before the user terminal performs multiple redirection attempts. This mediator role reduces the number of interaction rounds and significantly decreases the time delay while ensuring the user terminal acquires the correct page.
Solution Approach 2:
The WAP gateway performs preliminary action by querying the service provider in advance to determine if page redirection is required. This preliminary check occurs before the user terminal initiates any redirection operations, allowing the system to prepare the correct page location upfront and avoid multiple costly redirection interactions later.
2Reliability
If multiple redirection interactions occur between user terminal and service provider, then the user terminal can acquire the redirected page, but the wireless network bandwidth usage increases
Solution Approach 1:
The WAP gateway serves as an intermediary that consolidates redirection logic. Instead of multiple separate redirection interactions between the user terminal and service provider, the gateway performs a single proactive query to determine redirection needs, then provides the final destination to the user terminal in one operation, significantly reducing wireless bandwidth consumption.
Solution Approach 2:
The invention merges the redirection determination function into the WAP gateway, combining what would otherwise be separate interaction steps into a single unified operation. The gateway integrates the service provider's redirection information and presents it to the user terminal in one consolidated response, reducing the total number of wireless transmissions required.

AI summary
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.
