You can use the Push Service to develop a push-enabled app that runs on a BlackBerry device and receives push messages from a server-side app that is known as a Push Initiator. The server-side push initiator can deliver up to 8 KB of content (images, text, or audio) to many devices at the same time. You can develop a server-side push initiator to be used with a consumer or enterprise push app. For more information, see Server-side: consumer apps and Server-side: enterprise apps.
To use the Push Service, you must register with BlackBerry. For more information about registering, visit Push Service in the Platform Services documentation. If you're using the Push Service with BES10 or later, you don't need to register with BlackBerry. For more information, see Push technology for the enterprise.
The following architecture diagram shows a complete Push Service solution that includes the server-side library and the client-side library. The libraries work together to deliver content from the server-side app to a push-enabled client app.
- Push Initiator
The Push Initiator is the app that creates request messages using the server-side library and sends them to the Push Proxy Gateway (PPG).
- Server-side library
You can use the library of your choice to develop your server-side app. Some possibilities include:
- Push Proxy Gateway
The PPG processes push request messages that it receives from the server-side app. After the PPG processes a push request message, it sends a response message that communicates the overall result of the push message. The response message contains a result code or a PAP (Push Access Protocol) error code.
- Client-side library
The BlackBerry 10 WebWorks SDK contains the client-side library. The client-side library provides the APIs that the push-enabled app uses to create a Push Service object, create and destroy a channel, and receive push messages.
- Client-side push-enabled app
The client-side push-enabled app runs on a device and acknowledges the push request to the PPG. The client-side app uses the client-side library to create a Push Service object, create and destroy a channel, and receive push messages.
What can the Push Service offer?
- Increased efficiency
Using the Push Service, you can send content to:
- Individual users (unicast)
- Many users (multicast)
- All of your users (broadcast)
The server-side app sends the content when it's available so that data traffic is generated only when necessary.
- Runs in the background
The server-side app sends content as bandwidth becomes available so that it doesn't interfere with other apps.
- Minimal battery drain
The Push Service minimizes the impact on device batteries because the push-enabled app listens in the background for the server-side app to send content to it. The app doesn't need to poll the push server for content.
