NEW ORLEANS, LA. -- Tatara Systems, Inc., a developer of converged mobile service solutions for communications service providers, today unveiled at CTIA Wireless 2005 an IMS-compliant solution for fixed/mobile convergence voice and data services on the Tatara Mobile Services Convergence Platform.

IMS, based on SIP and being standardized in 3GPP, has achieved broad and general endorsement as the next-generation IP multimedia services architecture across major communications service provider segments. Tatara’s solution extends the reach of IMS to non-3G networks, including WLAN, DSL, cable, and WiMAX networks, while leveraging the core IMS infrastructure being deployed in communications service provider networks.

Tatara’s IMS solution consists of the Tatara Subscriber Gateway between the access network and the IMS core, and the Tatara Service Manager SDK which resides on today’s laptops and PDAs and emerging dual-mode handset and smartphone platforms (e.g. over Windows Mobile and Symbian).

The Tatara solution enables voice and data services that work securely and simply through NAT and firewalls as well as when the user is on a VPN. This allows the service provider to address both the consumer and enterprise market over both public networks, owned and roamed, and private networks. The Tatara solution has been validated by several large infrastructure vendors as complementing IMS core elements such as CSCFs, signaling gateways, media gateways, and media gateway controllers as part of an overall IMS solution architecture.

The Tatara solution also complements large infrastructure vendors providing pre-IMS fixed/mobile convergence services over today’s networks. This includes solving many of the specific service delivery and service consistency challenges associated with launching fixed/mobile convergence services within an enterprise and consumer setting.

One of the first fixed/mobile convergence solutions being offered by Tatara is SMS over IP, which allows communications service providers to seamlessly handoff SMS traffic from their legacy circuit network to an IP network (e.g., over WLAN). This enables “one number” access to all SMS based services such as message indication, business services, as well as entertainment applications when the user is on the IP network. This same solution is capable of supporting the roll-out of other voice and data services, including one number voice, MMS, WAP, and Location Based Services.

“There's a great deal of discussion about seamless mobility of services and applications between circuit and packet networks such as WLAN,” said Mark Lowenstein, managing director of Mobile Ecosystem and a leading expert on the wireless and mobile communications industry. “And users with dual-mode devices will want access to the same feature set whether they are on a circuit or IP network.”
