Core networks declare independence

17 февраля 2009

Nokia Siemens Networks brings benefits to operators with a new strategy focusing on hardware-independent solutions for core networks.

Nokia Siemens Networks is today introducing a new, open hardware architecture as a cost-effective option for deploying its market-leading and field-proven core network applications, such as mobile softswitching and IMS. The new architecture allows operators to benefit from new software-based multi-application platforms running on off-the-shelf hardware blades. 


By using commercial off-the-shelf (COTS) platforms, Nokia Siemens Networks’ customers can benefit from best-of-breed hardware that employs the latest advances in network server technology as they evolve their core networks to support Long Term Evolution/System Architecture Evolution (LTE/SAE). 


The long-term goal for the strategy is to provide an open, multi-application, hardware-independent platform for the evolution of core networks from traditional circuit-switched technology eventually to the All-IP environment of LTE/SAE. The same open hardware platform can be used for a variety of different network elements as operators upgrade and grow their networks. 


The strategy is already being applied to the MSC Server mobile softswitch (MSS), which is currently implemented on the Nokia Siemens Networks DX 200 hardware platform. Under the open hardware strategy, the MSS will evolve to open MSS software, which can be implemented on existing DX 200 platforms or on open COTS hardware. The versatility of the “open MSS” will let Nokia Siemens Networks’ customers deploy the same MSS features regardless of whether they are using DX 200 or COTS server technology, allowing them to expand their GSM, 3G or future LTE/SAE networks. 


“This is the beginning of a major shift in the way we design our core network products,” says Michael Clever, Head of Next Generation Voice and Multimedia, Nokia Siemens Networks. “The future of control servers clearly belongs to pure software solutions that give network operators more choices to meet their hardware requirements. It brings efficiency and flexibility. And it lets us concentrate on doing what we do best – developing superior, innovative software applications. This shift won’t happen across the industry overnight, and it doesn’t have to. But it’s coming, and we are more than happy to be the ones to kick it off.” 


By giving operators the option of choosing servers based on COTS technology, the open hardware strategy allows operators to take advantage of the latest innovative server designs and high performance blades. It allows operators to support a greater number of subscribers with a smaller equipment footprint and less power consumption, as well as better manage spare parts and maintenance. 


This open hardware approach is already being applied to other Nokia Siemens Networks core network “control plane” applications, such as IP Multimedia Subsystem (IMS) and the hiQ VoIP application server, which then can be combined with the MSS application.
