It is unclear where the bulk of the cuts will fall, but it said about 96 jobs in the UK were under threat as part of the €600m (£518m) cost cuts.
Nokia is playing catch-up on 5G, and also plans to invest in cloud computing and digital infrastructure research.
The company currently has 90,000 employees around the world, and has cut thousands of jobs since 2015.
"We currently expect the consultation process in the UK to cover an estimated 96 roles," a Nokia spokesperson said.
