Motorola has bought the privately-owned US company Leapstone Systems, which provides a software platform for delivering video, voice and data services across networks and multiple devices.

The focus of Leapstone has been "intelligent multimedia service delivery" for network operators, and this functionality will now be added to Motorola's end-to-end content delivery portfolio, stated Dan Moloney, President of Motorola Home & Networks Mobility.

"Leapstone will contribute its leading intelligent service delivery and content management platform to Motorola, which will serve as our new engine for enabling seamless mobility experiences across applications, devices and domains," said Moloney.

Leapstone's real-time system, its Communications Convergence Engine (CCE) suite, has been used by the like of Verizon Wireless and AT&T in the US to deliver content.

Terms of the deal have not been publicly disclosed.
