Nokia Siemens Networks said it has established a common core network for GSM, 3G and LTE for Tele2 Sweden that allows Tele2 subscribers to access an array of high-quality voice, data and real time multimedia services.

Tele2 is using Nokia Siemens Networks Evolved Packet Core (EPC) in their launch of Long Term Evolution (LTE) technology, providing faster mobile broadband.

Through the introduction of EPC into the Tele2 Sweden Core environment, Tele2 now has a common Nokia Siemens Networks Core offering supporting 4G/LTE, 3G and 2G mobile offerings for mobile data and traditional circuit switched voice telephony and IP telephony services.

In addition, Nokia Siemens Networks has also deployed its Subscriber Data Management and Subscriber Repository platforms based on the One-NDS offering, also including HSS (Home Subscriber Server) and EIR (Equipment Identity Register) functionality, which consolidates the subscriber data.

Under the contract, Nokia Siemens Networks is also upgrading the existing core network to support advanced redundancy functions and enable a clear path towards an all IP network.

The contract also encompasses implementation and maintenance services for these systems.

Nokia Siemens Networks head of sales for network systems Christian Fredrikson said with smart device users and the demand for data services increasing, Tele2 Sweden was looking to scale up its network.

"Our EPC prepares the operator for high-speed data services and also eliminates the need for additional elements in the transport network and achieves an optimised IP-based network architecture that secures the operator’s investments in the long run," Fredrikson said.
