The BlackBerry Internet Service Browsing network gateway
Wireless service providers can use the BlackBerry® Internet Service Browsing network gateway to offer BlackBerry device users access to the content optimization and compression features provided by the BlackBerry® Infrastructure without using the BlackBerry® Enterprise Server.
The BlackBerry Internet Service Browsing network gateway acts as a proxy for the BlackBerry® Browser, and makes requests on behalf of the BlackBerry Browser. The BlackBerry Internet Service Browsing network gateway optimizes the content in the response to enhance network efficiency and improve display on the smaller screens before it relays the content to the BlackBerry Browser.
The BlackBerry Browser accesses the BlackBerry Internet Service Browsing network gateway using the Internet browser configuration. The Internet browser configuration communicates with the BlackBerry Internet Service Browsing network gateway using HTTP/IPPP.
To browse the Internet through the BlackBerry Internet Service Browsing network gateway, users must specify the Internet browser configuration in the Browser Configuration settings.
To use the Internet browser configuration, a BlackBerry device user requires a service book that is issued to the BlackBerry device by the BlackBerry® Provisioning System.
