Introduces SIP-Based Application Server for Femtocell Network Integration and CDMA 1xRTT Mobile Convergence Solutions

ACTON, MA – March 31, 2008 – Tatara Systems, the leader in SIP-based femtocell convergence, today announced the availability of the Tatara CDMA 1xRTT Convergence Server (TCS/CDMA-1xRTT), a standards-based SIP/IMS service interworking application server for the delivery of CDMA 1xRTT services to SIP-based end points over a VoIP or IMS infrastructure. Network operators are seeking cost effective ways to transition their circuit-based mobile core to a next generation IP packet-based core, and the TCS/CDMA-1xRTT enables CDMA operators to preserve the significant investment in their existing mobile core, while selectively deploying new devices and services, such as femtocells, over this new packet core.

The TCS/CDMA-1xRTT supports all critical requirements for integrating femtocells into an operator’s mobile core, including authentication, voice calls, messaging, supplementary services, emergency services, and femto-macro handoff. It converges femtocells onto the mobile core via an IOS-SIP software adapter in the femtocell, and handles the service interworking and call state processing for controlling the flow of voice and messaging traffic over the IP packet core. The key benefit is a low cost convergence solution that exploits commodity IP infrastructure for transport and control, delivers service parity with the macro network, and enables operators to leverage their current mobile core assets. The TCS/CDM-1xRTT can be deployed in a VoIP or IMS environment, and supports standard IETF SIP or IMS-based ISC interfaces into the packet core, as well as an ANSI-41 interface into the CDMA 1xRTT core.

“The initial driver for Tatara’s convergence server initiative was SIP-based femtocell network integration, but our engagements with CDMA operators and femtocell ecosystem partners have confirmed there are compelling applications beyond femtocell convergence, including SIP-based IP-RAN macro network solutions,” stated E.Y. Snowden, President and CEO of Tatara Systems. “The Tatara CDMA 1xRTT Convergence Server offers operators a single, scalable platform that can be extended to support a broad range of mobile convergence applications, enabling CDMA 1xRTT services to be delivered to a variety of SIP-based end points.”

"A SIP-based approach offers mobile operators a more flexible, scalable way to integrate femtocells into their core network, especially those with fixed-line assets, or relationships with broadband service providers," said Roberta Wiggins, Research Fellow with The Yankee Group. "Tatara's CDMA 1xRTT Convergence Server can assist CDMA operators in delivering new mobile converged services, while leveraging their investment in a next generation VoIP or IMS packet core."

About the Tatara CDMA 1xRTT Convergence Server:

The Tatara CDMA 1xRTT Convergence Server can be deployed as a SIP-based application server in VoIP networks, and an IMS application server in IMS networks. It supports 1xRTT service authentication, and delivers voice, messaging, supplementary services, and emergency services to SIP-based end points, as well as support for femtocell to macro network handoff. The TCS/CDMA-1xRTT interfaces to mobile core elements including the HLR, MSC, and SMSC, using standard ANSI-41 Rev E. interfaces and protocols. It interfaces to the serving call session control function (S-CSCF) over the IMS service control (ISC) interface, and to the home subscriber server (HSS) using the Sh interface. The TCS/CDMA-1xRTT is delivered on a hardened, secure, high availability carrier-class hardware platform, with an embedded management system that supports Web, CLI, SOAP, XML, and SNMP management and alarming.

About Tatara Systems:

Tatara Systems is the first vendor to deliver a SIP-based solution for femtocell network integration, and a leader in enabling network operators to offer converged mobile services. The Tatara Convergence Server leverages a VoIP or IMS core to give any SIP-based end point presence on a mobile operator’s network. For femtocell applications, this ensures service parity with the macro network, but without having to tie radios directly into the mobile core, circumventing the attendant scalability and interoperability challenges. Tatara is a founding board member of the Femto Forum, and is working with its customers and partners to speed the deployment of femtocells worldwide.
