Tatara (News - Alert) Systems has launched 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.

 

The new 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. This server has the ability to support 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.

 

Tatara’ TCS/ CDMA- 1x RTT converges femtocells onto the mobile core via an IOS-SIP software adapter in the femtocell, and handles the service interworking as well as call state processing for controlling the flow of voice and messaging traffic over the IP packet core. This results in 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.

 

E.Y. Snowden, president and CEO of Tatara Systems, pointed out that the initial driver for Tatara’s convergence server initiative was SIP-based femtocell network integration, but their 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.

 

The Tatara CDMA 1xRTT Convergence (News - Alert) Server offers operators a single, scalable platform that can be extended to support a broad range of mobile convergence applications. This enables CDMA 1xRTT services to be delivered to a broad range of SIP-based end points.

 

Roberta Wiggins, Research Fellow with The Yankee Group (News - Alert), noted that 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.

 

She noted that 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.

 

The TCS/CDM-1xRTT can be deployed in a VoIP or IMS environment. The server 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.

 

Tatara Systems delivers a SIP-based solution for femtocell network integration, and enables network operators to offer converged mobile services. In another announcement, Tatara Systems said they are collaborating with AirWalk Communications, Inc. an industry innovator in IP Radio Access Network (IP-RAN) solutions, to deliver SIP-based femtocell and macrocell network solutions.
