STOCKHOLM -- Telenor Sweden has chosen Ericsson (NASDAQ:ERIC) as the sole supplier for a full-scale upgrade of the operator's core network, enabling voice over LTE (VoLTE), Wi-Fi calling and richer communication services experience to its customers.

Part of a five-year deal, the rollout will begin in the third quarter of 2015 with Ericsson implementing a full suite of products and services which will enable Telenor to offer HD voice and simultaneous surfing over LTE networks and richer communication experiences. With Wi-Fi calling, users will be able to use the operator voice service over their own home Wi-Fi access point, if cellular coverage is poor in their homes.

The core network upgrade will ensure that the high quality of services enjoyed by Telenor's subscribers will be maintained as the operator migrates the network towards the platforms of the future.

With almost two and a half million mobile subscribers, Telenor is one of the largest operators in Sweden, and under the terms of the agreement their user data subscriber architecture will also be upgraded to a more secure, reliable and simpler structure.

Stefan Jäverbring, CTO Telenor Sverige AB, says: "Ericsson's comprehensive portfolio and expertise will be a great asset to us as we upgrade our core network. The flexibility and scalability of the services deployed is just as important as their performance, and we believe this will provide an excellent platform for Telenor as we build Sweden's leading mobile network."
