Nokia Siemens is launching products at next week's Mobile World Congress that it expects will make LTE (Long Term Evolution) a closer prospect.

The company is launching two new products that will make up the key elements of its Evolved Packet Core (EPC) network solution for LET, allowing operators to modernise their core data network to support a wide variety of access types using a common core network.
The Flexi Network Server and the Flexi Network Gateway will enable operators to efficiently offer a comprehensive range of voice, data, high quality and real time multimedia services using the same ATCA base platform and will be available for early field deployment in the second half of 2009.
The Evolved Packet Core offering will ultimately support a full range of 3GPP access, such as 2G, 3G, HSPA and LTE. Nokia Siemens Networks' EPC can be conveniently deployed as an overlay solution for LTE alongside existing networks with minimum impact on present 2G and 3G services.
This pair of network elements, first of its kind, addresses the two contrasting aspects of next generation mobile networking: mobility management and connectivity. Flexi Network Server provides the higher than ever transaction capacity needed for complex mobility management tasks. Flexi Network Server is a logical continuation of Nokia Siemens Networks' Combi SGSN leadership in control plane transaction intensity in 2G and 3G networks.
