Nokia, the world's largest mobile phone manufacturer, is looking for further acquisitions to speed up the roll out of new services Niklas Savander, executive vice president of services and software, said in an interview.

Nokia bought US-based digital maps company Navteq for $8.1 billion (£4.6 billion) in July and has acquired ten smaller firms to jump-start its internet services business as the growth in the mobile phones market is set to stall.

"We're not done," Savander commented when asked about further acquisition plans.

Likely targets could be small companies which develop services Nokia itself plans to offer in the future, enabling the Finnish-based firm to roll those services out faster, he said.

In a media event later on Tuesday, Nokia will introduce The Files on Ovi service, based on the acquisition of Avvenu last year, which allows users to store files on the Web so that they are always accessible, an increasingly common service offered by internet firms like Google and Yahoo.
