BlackBerry devices support sending push requests through HTTP. Sybase Unwired Platform supports push configuration and notification handling APIs for BlackBerry HTTP push.
HTTP Push Gateway
Blackberry has an HTTP push feature for sending messages to occasionally connected devices. For Blackberry devices paired with BlackBerry Enterprise Server (BES), the HTTP push gateway contains an address that points to the HTTP listener of the BES server. The POST to the BES server has a query parameter that contains the device ID of the target devices (for example, 2100000a for an emulator). The BES server holds the message for a configurable amount of time, and delivers it to the device when the device becomes reachable.
Push Configuration APIs
The following APIs support push notification in the generated database class.
