Sun has updated its Java System Content Delivery Server (CDS).

CDS provides a common infrastructure for delivering all types of content, including Java applications, games, ringtones and wallpaper. It also lets operators create storefronts, viral marketing tools and payment systems.

New features include the Central Device Catalog to quickly aggregate content from various sources for a new device and then collect records of downloads. This lets the operator view usage patterns and segment customers, directing new content to the appropriate group.

Also at the show, Sun plans to announce that Telefonica Moviles Espana and Taiwan's Chunghwa Telecom have chosen Sun Fire servers and the Solaris 10 operating system to deliver services to their customers.

Sun will also talk more about its link-up with Nokia and Ericsson where the companies will jointly develop requirements for a standardised, integrated telecommunications platform. If network equipment providers follow a common set of open standards in their products, it will be easier for carriers to integrate gear from different suppliers and ultimately get revenue-producing services out more quickly, Sun said.
