Nokia and NEC have established VoIP sessions and transferred instant messages between terminals over a network using new IP Multimedia Subsystem (IMS) technology. 

"IMS is a technology that enables devices, both mobile and fixed, to interconnect via IP," said Kalle Luukkainen, marketing director of core networks at Nokia. "It supports a number of multimedia services, such as video sharing, content sharing and sharing of presence information, either on a one-to-one or one-to-group basis."

The Nokia-NEC test demonstrated interoperability of devices not only between suppliers but also across networks, according to Luukkainen.

"This is a very open technology that enables mobile terminals or other computing devices from one supplier to connect with those of another," he said.

Another service that will work over IMS is push-to-talk, a walkie-talkie style service that many mobile operators around the world are interested in, according to Luukkainen.

Mnay operators and suppliers, including Nokia, have been conducting IMS tests over the past several months.

The technology is "access agnostic", Luukkainen said, meaning that it can support all wireless and wireline access technologies capable of packet-based IP connections.
