Feature Description
The Content Filtering (CF) service prevents subscribers from inadvertently getting exposed to universally unacceptable content, or content that is inappropriate as per subscriber preferences. Based on the URLs in the subscriber requests, the CF service filters HTTP and WAP requests from mobile subscribers. Operators can filter and control the content for an individual subscriber to access.
The CF service provides the following solutions:
-
URL Blacklisting—In this solution, all HTTP or WAP URLs in subscriber requests must match against a database of "blacklisted" URLs. If there is a match, it discards the flow, redirects, or terminates as per the configuration. In case of no match, subscribers view the content as usual.
URL Blacklisting may not be a subscriber opt-in service. Operators can enable URL Blacklisting either for all subscribers or for a subset of subscribers. Typical cases include applying a blacklisted database of child porn URLs to all subscribers so that they are inadvertently not exposed to the universally unacceptable content.
-
Category-based Static Content Filtering—In this solution, all HTTP or WAP URLs in subscriber requests must match against a static URL categorization database. Action initiates based on the URL's category and as per the configuration in the subscriber CF policy. Possible actions include:
-
Permitting
-
Blocking
-
Redirecting
-
Inserting content
