Pushed content delivery
You can notify users that new content is available or, depending on the network gateway, you can push new content directly to the BlackBerry® device.
The level of support for pushing content depends on the network gateway.
- BlackBerry® MDS Connection Service: Among the three network gateways, the BlackBerry MDS Connection Service offers the most support for pushed content delivery. Content is pushed directly to the BlackBerry device and is stored in a dedicated cache for pushed content. You can develop the push service to place an icon on the Home screen (the icon changes to notify the user of new content), to send the content to the message list (that appears like any other message), or to deliver the content directly to the cache without any user notification. When the user next views the content, it is available on the BlackBerry device; the user does not need to download it.
- BlackBerry Internet Service Browsing: The BlackBerry Internet Service Browsing network gateway supports pushed content delivery. Content is pushed to the BlackBerry device through web signals using a push/pull architecture. You can develop a web signal to place an icon on the Home screen. The icon changes to notify the user that new content is available, prompting the user to download the content.
- WAP network gateways: WAP network gateways support pushed content delivery, typically of SMS or UDP messages, depending on the network. To support pushed content delivery through WAP network gateways, the WAP Push service record must be provisioned on the BlackBerry device. WAP Push service records are typically provisioned when a BlackBerry device is registered with the wireless service provider.
