In a press release today, Nokia Siemens Networks (NSN) gives details of its implementation of a common core network for GSM, W-CDMA/HSPA and Long Term Evolution (LTE) services for Tele2 Sweden. Tele2 is using NSN’s Evolved Packet Core (EPC) in its expansion of LTE mobile broadband services, which it launched in mid-November via a joint network venture with Telenor Sweden, Net4Mobility, in Stockholm, Gothenburg, Malmo and Karlskrona, under a plan to achieve 99% 4G population coverage by the end of 2012. The EPC is supporting 4G, 3G and 2G mobile data as well as traditional circuit switched voice telephony and IP telephony services. In addition, NSN has deployed its Subscriber Data Management and Subscriber Repository platforms based on the One-NDS solution, also including HSS (Home Subscriber Server) and EIR (Equipment Identity Register) functionality, which consolidates the subscriber data. Under the contract, NSN is also upgrading the existing core network to support advanced redundancy functions and enable a clear path towards an all-IP network. ‘With smart device users and the demand for data services increasing, Tele2 Sweden was looking to scale up its network,’ added Christian Fredrikson, head of sales for Network Systems, NSN, who continued: ‘Our EPC prepares the operator for high speed data services. It 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.’
