OracleAS Wireless Deployment

OracleAS Wireless applications can be deployed for many different types of access, including wireless Internet browser, two-way ASK messaging, voice, J2ME devices, and delivery of alerts and notifications. Because of this flexibility, it is desirable to have a single application delivery via multiple channels. The Multi-Channel Server is designed specifically to meet this need.

The Multi-Channel Server delivers device-independent content based on the device’s capabilities and ensures compatibility with new and emerging devices. In effect, the Multi-Channel Server provides a common interface that eliminates the need for device-specific applications. It enables the adaptation of text, images, ring tones, voice grammars, and audio/video streams for each device type. For example, if an application generates GIF images, and the device supports only Wireless BitMap (WBMP) format, the adaptation engine adapts the image to WBMP before it is sent to the device. The Multi-Channel Server also supports standard markup languages and provides the XForms engine. Devices are detected as they make requests. The Multi-Channel Server supports URL caching and can be deployed within existing portals.

Browser-based applications are developed using the OracleAS Wireless XML or XHTML languages. Data is accessed using these applications in a synchronous fashion via wireless Internet-connected devices. The typical communication protocols used for deployment include CDMA and 1xRTT; ...
