Tatara Systems, the leader in SIP-based femtocell convergence, today announced the selection of Continuous Computing’s Trillium^® MAP IS-41 protocol stack to be employed within its femtocell convergence solution, the Tatara Convergence Server (TCS) for CDMA networks.

The Tatara Convergence Server solution enables the interconnection of femtocells and other advanced technology IP-based radio network elements with the legacy macro wireless network, providing the full mobile voice, messaging and data experience in an IP environment supporting both VoIP and IMS networks. The TCS capabilities include authentication of the mobile subscribers, handoff between femtocells and the macro network, emergency and supplementary services, as well as delivering new IP-based applications to existing mobile handsets without modifying or disrupting the existing macro network.

Tatara has staked out an early leadership position in the femtocell market as the first vendor to deliver a SIP-based solution for femtocell network integration. As noted by most industry analysts, IP-based femtocell deployment is the only method that offloads the legacy mobile core infrastructure, thereby providing the capacity needed for 3G service delivery and enabling operators to recognize substantial cost savings through OPEX and CAPEX optimization. Tatara’s method for femtocell network integration, based on a SIP-based femtocell convergence server, is the architectural model that the 3GPP2 organization is currently working to ratify as the CDMA standard for SIP/IMS-based femtocell deployments.

Continuous Computing’s Trillium Mobile Application Part - IS-41 (MAP-IS-41) portable software product provides the functions and procedures to query various databases or support other components in the intelligent network (e.g., VLR, HLR, MSC, AC, SME). Trillium MAP - IS-41 software supports the IS-41 Rev C and D variant of the protocol and supports key functions for prepaid charging services and wireless number portability services. Trillium MAP IS-41 is just one critical component of the broad Trillium Wireless family of protocol stacks which stretches from 2G through LTE and includes support for GSM, GPRS, CDMA, WCDMA (3G HSPA+), and LTE femtocell, edge and core network solutions.

“Continuous Computing’s industry-proven Trillium MAP IS-41 protocol stack is the foundation of much of today’s deployed CDMA networks,” said Manish Singh, vice president of product line management for Continuous Computing. “The Trillium MAP IS-41 stack ensures interoperability and complies with the latest standards supporting a wide array of IS41 based services. We are delighted that Tatara Systems has picked the Trillium MAP IS-41 stack for its femtocell solution.”

“Continuous Computing was chosen due to their compliance, deployment history, and notable references,” stated E.Y. Snowden, president and chief executive officer for Tatara Systems. “As early innovators in the femtocell market, we strive to ensure complete interoperability and reliability within our solutions.”
