The IMS (IP Multimedia Subsystem) and the NGN (Next Generation Networks) Forums have announced the successful completion of interoperability testing at the IMS Forum Plugfest 4 and plans for the NGN Plugfest 5.
Plugfest 5, scheduled to take place in June at the University of New Hampshire InterOperability Lab (UNH-IOL), will test consumer and enterprise M-play interoperability.
Plugfest 4, held at the UNH-IOL Feb 25-29, was the latest in a series of events designed to deliver IMS and NGN interoperability and certification.
Participating companies tested a number of leading technologies and services for interoperability including triple play, VoIP, fixed mobile convergence (FMC) from multiple vendors, test and measurement equipments, SIP (session initiation protocol), class-5 features (voicemail, etc), Diameter IMS stacks and instant messaging with presence support.
In addition, Plugfest 4 was expanded to include billing interfaces for charging for IMS services.
Tests included an IMS-compliant charging/billing system working with multiple network configurations, as well as interoperability of operational support systems and business support systems (OSS/BSS).
