July 21, 2011 - RICHARDSON, Texas -- Taqua®, LLC, a leading supplier of convergence switching and small cell deployment solutions, today announced it has completed the acquisition of Acton, MA-based Tatara Systems, the leading provider of SIP-based mobile telephony convergence solutions.

Driven by smartphones and other data-intensive mobile device usage in both the consumer and enterprise markets, the mobile industry is looking to small cell deployments as a principal solution for addressing network capacity challenges, data off-load requirements, and in-building coverage issues.  Tatara’s mobile telephony convergence platform is designed to address these issues and is widely deployed today.

Founded in 2001, Tatara Systems has focused exclusively on developing applications for the mobile convergence market, the first of which is for femtocells. Tatara is the recognized leader in SIP-based femtocell convergence solutions and led the efforts within 3GPP2 to define a standard compliant femtocell convergence server. The Tatara Convergence Server (TCS) utilizes a flat, SIP-based architecture supporting both CDMA and UMTS, which allows for easier core network integration while providing a carrier grade platform that is highly scalable and future proofed for 4G including VoLTE.  The TCS caps circuit switch investment by enabling off-load and laying the groundwork to provide services beyond femtocell.   Within its first tier one CDMA mobile operator femtocell deployment, the TCS delivers voice, messaging, and data convergence while providing supplementary, regulatory, and emergency services. The solution also enables seamless femto to macro handoff.

“The addition of Tatara’s Convergence Server platform and femtocell convergence application software fits nicely with our wireless media gateway and small cell backhaul efforts,” said Eric Pratt, chief executive officer of Taqua, LLC.  “While important from a product diversification standpoint, it’s also key for Taqua from a corporate perspective as it broadens our go to market channels and establishes Taqua’s solutions within tier one wireless carriers.”

The TCS is deployed in pre-IMS and IMS networks, including the largest and fastest growing femtocell deployment to date.  In pre-IMS networks, it is an application server operating as a SIP-MSC/IWF, while in IMS networks it operates as a SIP Application Server.  The TCS extends macro network features and functions to femtocell-served subscribers.  It leverages incumbent core network elements enabling mobile operators to deploy new femto offerings while preserving existing systems and practices. It also allows operators to deliver a consistent user experience and implement unified service plans across femto and macro networks.

The TCS will be branded by Taqua as the TCS6100™ Convergence Server (TCS).  It will be sold separately and in conjunction with Taqua’s existing femtocell gateway offering - the T7000™ Intelligent Switching System (T7000).  In femtocell deployments, the T7000 performs the MG/MGCF/MRF functions.
