Content Filtering

Content Filtering is an in-line service available for 3GPP and 3GPP2 networks to filter HTTP requests from mobile subscribers based on the URLs in the requests. This enables operators to filter and control the content that an individual subscriber can access, so that subscribers are inadvertently not exposed to universally unacceptable content and/or content inappropriate as per the subscribers’ preferences.

Content Filtering Configuration

Use the following additional configuration to enable the content filtering:

configure 
   require user-plane content-filtering 
      content-filtering category database directory path path_address 
      content-filtering category database max-version version_number 
      end 
Note

The above configuration must be configured on the UPF, during boot time, to enable Content Filtering. Defining the above configuration post the User Plane configuration will lead to errors and inconsistencies.
