Nokia and TeliaSonera to cooperate in trials for developing the networks of tomorrow

Nokia and TeliaSonera have entered into an agreement to develop Next Generation Network technologies, architectures based on IP Multimedia Subsystem (IMS), Session Initiation Protocol (SIP) and other technologies that will define the "networks of tomorrow."

IP Multimedia Subsystem (IMS) and Session Initiation Protocol (SIP) are the key enablers of service convergence between different access technologies. The Nokia IMS enables operators to deploy IP-based person-to-person multimedia services in 2G and 3G networks. It allows terminals to establish IP sessions between each other, which in turn enables a wide range of multimedia communication services and interactive applications. SIP technology makes IP-based person-to-person services possible.
