At CTIA’s Wireless 2007 trade show next week, Azaire Networks will be showing off its new CDMA network component addressing the packet data interworking function in pre-IMS networks. The PDIF component is part of Azaire’s IP Converged Network Platform with eXtended Mobility (IP-CNP with XM).

The new CDMA component enables seamless roaming between CDMA1x/EVDO and wireless LANs, handover of voice calls between packet and circuit-switched domains, as well as integration with IMS, Verizon Wireless’ Advances to IMS initiative and other VoIP networks, Azaire said.

PDIF was built in to the 3GPP2 standard for fixed-mobile convergence, and it’s responsible for security, access, authentication and policy enforcement. The IP-CNP with XM is 3GPP2-compliant and combined with Azaire’s Authentication Engine, it provides the baseline security framework for WLAN, femtocell and WiMAX implementations of fixed/mobile convergence, the company said.
