The software enabling this transformation is Artilium’s Real-Time Architecture (ARTA) for Connected Mobile Services, designed to facilitate rapid creation of new mobile applications, packaged as services. The software platform is almost entirely designed by Artilium on the Microsoft product portfolio.

The partnership includes a licensing agreement allowing KPN deployment of ARTA as a platform for next-generation converged services across its growing base of over 27 million mobile subscribers in the Benelux, Germany and Spain.

KPN Mobile International Chief Executive Officer, Stan Miller said,” This agreement is a major boost for KPN’s strategy on MVNO’s ( Mobile Virtual Network Operators) in Europe. Artilium software allows KPN to surge to the forefront of mobile/Web innovation. We are able to open our network to developer communities worldwide to deliver an infinite range of differentiated services and an exciting new level of personalisation and interactivity for subscribers. In doing so, we begin to transform the very essence of our business creating new service-centric business models across a broad value-chain that includes developers, advertisers and our commercial partners.”

“Artilium unifies IP, PSTN, ISDN and GSM network communications and provides the framework that securely opens the mobile network to rapid application innovation ,” said Artilium Chief Executive Officer Robert Marcus. “We are delighted to be partnering with KPN in this groundbreaking work that brings with it an unprecedented level of business model originality and value-chain diversity.”

Commenting on the agreement, Steve Zimba, Managing Director Global Telecom Business at Microsoft Corp. said:  “We are excited that KPN and Artilium have chosen the Microsoft platform to power their ecosystem of connected mobile services. We will be working closely together to help make this great vision a compelling reality for the millions of consumers who are eager to embrace rich, personalized and contextually-aware mobile experiences.”
