Architecture: Framework for delivering content to BlackBerry devices using push technology

The framework that uses push technology to deliver content to BlackBerry devices uses a client/server model. With pull technology, a server waits for a device to request content. In contrast, push technology enables your server to initiate the content delivery to a device without receiving a request.

The framework includes the protocols, service interfaces, hardware entities, and software entities that you can use to deliver content to BlackBerry devices using push technology.


This diagram shows the elements that are described in the following text.
