Nokia Siemens Networks (NSN) is close to selling its Business Support Systems division, according to Bloomberg sources, with US-based Amdocs and private equity firms having shown interest. The division helps operators manage their billing systems and could fetch as much as EUR300 million, the sources said.

NSN has sold a number of its businesses as part of a restructure aimed at making it into a mobile broadband specialist. Speaking at Mobile World Congress in February, CEO Rajeev Suri said he wanted the company to become the industry’s leading player in the sector.

In an emailed response sent to Bloomberg, Nokia Siemens spokesman Ben Hunt said: “Business areas not consistent with the new strategy are planned to be divested or managed for value, and we have already announced the divestment of a number of these business.”

In the past year, NSN has sold its WiMax unit to NewNet Communication Technologies, its Expedience proprietary fixed wireless broadband business to CN Tetragen, its fixed line broadband access unit to Adtran and microwave transport business to DragonWave.

The business restructure accompanied an announcement in November 2011 that the company was planning to cut 17,000 jobs and EUR1 billion in costs by the end of 2013 in response to economic pressures that have seen spending on mobile network infrastructure decline.
