Continuing its efforts to empower service providers to provide seamless and ubiquitous voice, video and data service to subscribers across any 4G mobile network, Nortel Carrier VoIP and Application Solutions unveiled new wireless and 4G Mobile VoIP solution enhancements that equip carriers to deliver a superior user experience, reduce network deployment costs and speed time to market.

Nortel CVAS' 4G Mobile VoIP solution equips operators to integrate seamlessly with all cellular technologies, including 2G, 3G and the latest 4G LTE and WiMAX networks. The solution delivers a consistent set of voice, messaging and multimedia services to all of the subscriber's devices, with seamless hand-off across WiFi, GSM 2G/3G, CDMA 2G/3G, HSPA/+, WiMAX and LTE networks.

Nortel CVAS' new enhancements in 4G Mobile VoIP equip carriers with advanced routing capabilities for querying a Home Location Register (HLR) to optimize call routing into the cellular network, billing enhancements to facilitate billing correlation between legacy cellular and SIP networks, and roaming support on a foreign cellular operator's network. The solution offers integrated wireless signaling gateway capability that allows operators to leverage their existing OAM systems for fault management, performance management, provisioning and billing. Subscribers can enjoy a better communication experience because the solution enables seamless hand-off between mobile and broadband networks, as well as advanced features like single identity, presence, web-based call screening, visual voicemail, and SMS to IM interworking.

Nortel CVAS is implementing the first large scale 4G VoIP network that offers voice continuity between 4G mobile VoIP, existing 2G/3G cellular voice and WiFi. In addition, Nortel CVAS has deployed VoIP solutions that leverage the subscriber's laptop and mobile device in parallel for call control and multimedia service enrichment.

Nortel CVAS 4G Mobile VoIP solution enhancements are expected to be available in the second half of 2010, and are powered by the latest software releases of the Nortel CVAS' Adaptive Application Engine SIP software engine (Rel A2E 8.0). The solution can be deployed as a stand-alone SIP Application Server, as a 3GPP IMS-compliant application server or as an upgrade for carrier customers who have already deployed Nortel's industry-leading Communication Server 2000 IP Multimedia softswitch.

At this week's CTIA Wireless 2010 tradeshow, John McCready, vice president of product management, CVAS, Nortel, will join other industry leaders in a panel discussion on the topic of "Off Portal Content – Coming Full Circle." The panel will take place on March 24 from 1:00- 2:15 p.m. at the Las Vegas Convention Center in room N110.
