ORLANDO--Tekelec and Hewlett–Packard announced at the Wireless 2007 trade show here an interoperability and marketing partnership focused on accelerating IP multimedia subsystem deployment.

The joint solution follows the completion of interoperability testing between the Tekelec TekCoreTM Session Manager--a call state control function platform--and the HP OpenCall home subscriber server (based on HP’s traditional home location register technology).

In addition to this core infrastructure, the overall solution also includes service enablers, operational and business support system linkages, and application service offerings that enable the delivery of subscriber-centric services spanning wireless, wireline and broadband networks. The enablers include the IMS Service enablers such as the media resource function (MRF), presence server, electronic numbering (ENUM), group list management and voice call continuity platforms. Among applications are enhanced voice services, instant messaging and multimedia content sharing.

The companies have deployed the joint solution, including third-party IMS applications such as multi-instance gaming, in the HP Intel Solution Center in Richardson, Texas, according to Jerry Earle, vice president of communications, media and entertainment , Americas for HP. In addition, Tekelec and HP are working with service providers to extend their IMS trials with the new elements of the joint IMS-based solution.

“If you look at what we’ve got and what Tekelec’s got, there’s really no overlap, and we serve very complementary functions in the network,” Earle said.

Frank Plastina, president and CEO of Tekelec, added that unlike some other IMS-related vendor alliances that are more focused at the research and development level, this partnership is ready for market. “The sales teams on both sides have been involved from the very beginning of this agreement to look at how you sell this combination of functionality to the market,” he said. “Too often in this industry, we go looking for the next innovation that can be produced by such an agreement and then push it out there at the sales guys, who have to figure it out and figure out how to work together.”

The HP OpenCall HSS and the Tekelec TekCore run on ATCA-based HP blade servers.
