TeliaSonera carried out thorough testing of platforms from several major IMS vendors before making its decision, as well as conducted interoperability trials on IMS and SIP (Session Initiation Protocol) with the GSM Association and other leading operators and equipment makers. The comprehensive and successful evaluations convinced TeliaSonera that new services based on IP, such as video sharing, will function smoothly across networks and national boundaries from Day One.

“We have been pleased by the capabilities of the Nokia Siemens Networks’ platform and are happy to take this step in the evolution of our network together with Nokia Siemens Networks,” says Ove Alm, Chief Technical Officer, TeliaSonera Broadband Services.

“We are extremely proud that TeliaSonera has chosen us to supply the key technology for its future service offering,” says Jan Jansson, who heads Broadband Sales for Nokia Siemens Networks. “We recognize the high standards that TeliaSonera expects from its technology partners, and are excited by their confidence that we can meet and exceed those standards. Our IMS is second to none, and we aim to help TeliaSonera roll out the most interesting and useful services on the market.”

Nokia Siemens Networks’ IMS is an open, standardized system for combining mobile and broadband services, making it possible for end users to seamlessly access the same services over mobile, fixed and WLAN networks. For example, IMS will allow them to make calls, send messages, engage in instant messaging, and view videos and photos, regardless of how they access the network. Users can also have the same address book on their fixed phone, mobile and broadband terminals, and can see whether the person they want to contact is offline or busy.
