AKA is a key component that will enable operators to respond to increasingly complex subscriber demands for secure fixed-mobile convergence – and still maintain high levels of scalability and performance

NextPoint™, a leader in fixed-mobile convergence (FMC) solutions, today announced the successful completion of interoperability testing in an IP Multimedia Subsystem (IMS) topology that included multiple functions and vendors. The multi-vendor testing took place during the IMS Forum’s IMS Plugfest™ IV interoperability test event held on February 25-29 at the Interoperability Lab at the University of New Hampshire Interoperability Lab (UNH IOL).

This testing was the first to demonstrate successful VoIP calls between different IMS-compliant User Equipment (UEs ) using the IMS Authentication and Key Agreement (AKA) signaling for mutual authentication. As part of the test topology, the NextPoint Universal Convergence Gateway (UCG) functioned as the Proxy-Call Server Control Function (P-CSCF) as the secure point of entry for UEs to access IMS services. Other topology components included the HP OpenCall Home Subscriber Server (HSS), the Serving Call Session Control Function (S-CSCF) from Sonus and UEs from Radvision, Aricent, and Alpha. As standardized by the 3rd Generation Partnership Project (3GPP), IMS provides for the delivery of converged services to mobile and fixed subscribers.

“In its continuing participation in the IMS Forum’s interoperability testing, NextPoint was able to demonstrate that the UCG can provide subscribers secure access to network services,” said Scott Poretsky, director of Carrier Network Engineering at NextPoint and Technical Co-Chair for the IMS Forum. “The authentication process was completed and calls were securely made between UEs from different vendors through the NextPoint UCG. This demonstrates that the vision for service delivery across interoperable interfaces between best-of-breed components in a multi-vendor network is achievable today.”

In addition to the industry benefits of a deeper demonstration of proven authentication as a result of the IMS-AKA signaling testing at IMS PlugFest IV, NextPoint continues to identify operational efficiencies and enhancements to the UCG in this expanded interoperability testing environment.

“AKA is a key component that will enable operators to respond to increasingly complex subscriber demands for secure fixed-mobile convergence – and still maintain high levels of scalability and performance,” said Amir Einav, manager, Strategic Marketing, OpenCall Software, HP. “HP is pleased that its HSS solution and its subscriber data management expertise played a key role in the test with NextPoint and other participating companies. The successful interoperability test is a milestone in the road to IMS-based next generation networks.”
The IMS Forum's Plugfest IV was the fourth in a series of events designed to develop reliable interoperability and certification for IMS services and applications. NextPoint participates in the plugfests to further the benefits of IMS, which creates a common services layer to provide operational cost-savings in the delivery of media-rich and mobile services. NextPoint believes that because of the type of interoperability testing that takes place at IMS plugfests, service providers can be confident in their IMS NGN investments.
