New Unisys Communications Solutions Empower Telecom Providers to Serve More Mobile Subscribers at Lower Cost

New generation of VoiceSource Express servers helps providers expand mobile subscriber base and deliver innovative, secure value-added services

BLUE BELL, Pa., Feb. 20, 2013 /PRNewswire/ -- Unisys Corporation (NYSE: UIS), a longtime provider of high-volume messaging solutions to the world's leading telecommunications services providers, today announced the two newest members of the Unisys VoiceSource Express (VSE) family of communications platforms: the high-end VSE420 and the entry-level VSE46.

The VSE420 provides an ideal solution for large telecom providers serving tens of millions of subscribers, while the VSE46 is designed for smaller providers in regions where mobile use is rapidly expanding – especially Latin America and Africa.

The Unisys VSE communications solutions help telecommunications providers grow revenue by providing integration with social media networks, advanced call control and mobile advertising, among other key capabilities.

The solutions can also combine with Unisys Stealth Solution for cybersecurity to offer regional and international communications providers a secure, scalable, economical way to provide new value-added services to their consumer and enterprise customers.

"We continue to expand Unisys solutions to help telecom providers generate new revenue, while continuing to reduce cost per subscriber through powerful, highly scalable VSE systems," said Steven Chuey, vice president, Global Communications Solution Management, Unisys. "The new VSE420 platform provides scalability that our competitors are hard-pressed to match, while the new VSE46 provides the same cost-effective solution for smaller service providers. In addition, our innovative service development environment provides fast prototyping and testing so telcos can speed up the time-to-market for new subscriber services."

New Solutions Benefit from Advanced Architecture and Security Technology

Based on Unisys ClearPath server technology using powerful high-end members of the Intel® Xeon® Processor family, the VSE420 and VSE46 provide highly scalable, fully redundant solutions. The platforms significantly reduce footprint and power consumption, resulting in better data center performance per watt and lower operating expenses.

Each VSE420 server can support up to 8 million subscribers, and up to 24 million subscribers in a three-system cluster. Multiple VSE clusters enable support for far larger numbers of subscribers.

The VSE46 platform provides a cost-effective entry level system that supports up to 2.5 million subscribers per system. As with the VSE420, clustering provides the scalability required for growth.

The VSE420 and VSE46 platforms continue to provide Unisys' rich suite of messaging services, including visual voicemail for iPhone, Android, and Windows devices; advanced notification services such as Missed Calls and Call Me Now presence notification; Find Me/Follow Me for call delivery anywhere; Voice SMS and MMS services; voice-to-text translation of messages sent to subscribers via e-mail, SMS, MMS, social media sites or the web; and posting of messages to Facebook and Twitter from any mobile device.

The VSE solutions enable providers to add innovative features to services, such as automatic reverse call, reverse SMS, intelligent 0800 call routing, sponsor calls, mobile ad insertion and multi-channel broadcast/interactive marketing campaigns.

Providers can use Unisys Stealth Solution in conjunction with Unisys VSE solutions. Unisys Stealth conceals applications and associated information from hackers. Combining VSE with Stealth, providers can implement highly secure connectivity for sensitive applications and communities of interest – groups of people authorized to share information, with that information protected from unauthorized use by members of another community.

Unisys will showcase the new VSE solutions at Mobile World Congress 2013 in Barcelona, Spain, February 25-28.

As enterprises capture more and more data of all types – structured, semi-structured, and unstructured – data discovery requirements for business intelligence (BI), Big Data, and predictive analytics initiatives grow more complex. A company’s ability to become data-driven and compete on analytics depends on the speed with which it can provision their analytics applications with all relevant information. The task of finding data has traditionally resided with IT, but now organizations increasingly turn towards data source discovery tools to find the right data, in context, for business users, d...
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...
Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated and cloud solutions through hybrid hosting – a sustainable solution for the data required to manage I...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...

Who are you? How do you introduce yourself? Do you use a name, or do you greet a friend by the last four digits of his social security number? Assuming you don’t, why are we content to associate our identity with 10 random digits assigned by our phone company?
