Speech Design's products and services include Next Generation Messaging, Call Completion and other innovative added-value carrier solutions. Their universal, open-standards-based THOR platform is capable of integrating multiple services on a single system, offering carriers unprecedented flexibility and reduced cost of ownership. More than 130,000 companies and millions of individual users benefit daily from Speech Design's added-value communications solutions delivered by their partners: premier suppliers of enterprise and public networks.

The company has developed a new 'Call Completion and advanced messaging' solution, designed to address a large challenge in the wireless industry: the roughly 40 percent of all calls that are never directly connected - usually due to the recipient being on another call, busy, in an area of poor service, or having their mobile device turned off. By improving these situations in a seamless way, wireless carriers can increase their customer's satisfaction and productivity - while recovering 'lost' revenue from these calls. Speech Design's Product provides users with advanced SMS messages to make it easier to re-connect missed calls, for both the sender and receiver and also advanced messaging options for absolute comfort and convenience.

This system is based on MySQL Cluster Carrier Grade Edition, Sun's high-availability open source database, especially designed and certified for use in carrier grade communications environments, such as Subscriber Data Management systems (HLR, HSS) and in Service Delivery Platforms.

"MySQL Cluster database delivers carrier-grade levels of availability and performance with linear scalability on commodity hardware", stated Jan Martens Managing Director, Speech Design Carrier Systems GmbH.

Speech Design is using MySQL Cluster Carrier Grade Edition as a key component of the THOR application platform. MySQL Cluster is responsible for core functions and services of the THOR Call Completion and Next Generation Messaging System. With the carrier grade availability and high throughput architecture, it helps to ensure time-critical operations for message transactions and notification events. The database also stores global service configurations and messaging rule sets, as well as logging all user activity via Call Detail Records. These CDRs allow accurate billing, revenue assurance and network/service statistics via the operators OSS/BSS (Operations Support Systems / Business Support Systems) infrastructure.

By selecting MySQL Cluster Carrier Grade Edition for its commercial offering, Speech Design was able to:

• Improve developer productivity to accelerate time-to-market
• Achieve 99.999% carrier-grade availability with consistent millisecond response times
• Handle massive subscriber growth through dynamic scalability
• Provide redundancy across multiple sites through Geo-Replication
