Nokia and NEC Corp. have 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 voice over IP as well as transferred instant messages between test terminals.

IMS enables both mobile and fixed devices to establish IP sessions between each other. These connections form the basis for a wide range of multimedia communication services, such as sharing presence information, interactive applications, sharing content and sharing real time video. Also push-to-talk over cellular, the voice service for one-on-one and one-to-group communications, will work over IMS. IP multimedia services can be accessed over any IP connection, such as GPRS and WCDMA networks, broadband home connections or WLAN hotspots.

In addition, the trials are also being used to look at issues related to roaming at the service level. The ultimate objective is to have roaming for IMS-based services, allowing users to access the services of their home country even when they are abroad.
