Nokia and NEC completed the first phase interoperability testing between the two companies’ IP Multimedia Subsystems (IMS). The testing program verified the functionality of major IMS features over an IP network connecting Europe and Japan. During the tests, Nokia and NEC established sessions for VoIP as well as transferred instant messages between test terminals.
Standardized in 3GPP Release 5, IMS is designed to allow service access and interoperability between operators and vendors. The companies said the success of these trials has shown that the industry’s long IMS standardization efforts are starting to bear fruit as IMS standards are now mature enough for compatible implementation by different vendors. This points the way to the commercial introduction of advanced real-time and near real-time multimedia services. http://www.nokia.comhttp://www.nec.com
