The BlackBerry Browser retrieves the icons without user intervention, and replaces the standard icon with the notification icon
on the Home screen. When the user clicks the notification icon, the BlackBerry Browser opens and retrieves the content from the
URL specified in the push request. After the user clicks the notification icon, the BlackBerry Browser replaces the notification
icon with the standard icon on the Home screen.

Pushed content supported by WAP network gateways

To push content through a WAP gateway, a WAP Push service record must be provisioned on the BlackBerry® device. WAP Push
service records are typically sent during registration. On the BlackBerry device, the WAP Push service record specifies how the
BlackBerry device receives WAP pushes, on which ports the WAP Push Processor listens for incoming WAP Push messages, and
how the BlackBerrydevice manages the incoming messages.
Server applications can push content to the BlackBerry device using one of the following methods:
•
Existing WAP connections: This method is available only when a WAP connection is open between the BlackBerry device
and the WAP gateway.
•
SMS messages: If an existing WAP connection is not available, the service record provisioned for the GPRS and CDMA
networks typically uses SMS.
Wireless service providers can restrict incoming SMS messages to specific source addresses. The source address restrictions
are specified as parameters in the WAP Push service record.
•
UDP messages: If an existing WAP connection is not available, the service record provisioned for the iDEN® network typically
uses UDP.
Push message types
service indicator
service loading
When a pushed message is successfully or unsuccessfully processed by the BlackBerry® Browser, a push completion notification
is sent to the push initiator.
By default, the browser handles service indicator and service loading messages automatically. Users can change how incoming
pushed messages are handled, or turn off WAP Push support in the browser configuration properties.

Description
These messages are self-contained with some text to inform the user about an event
or notification. The entire text of the message is included in the service indicator
that is pushed to the BlackBerry device.
These messages include a URL at which the new content is located. The service
loading message is pushed to the BlackBerry device first, and then the browser
automatically downloads content from the URL location.
