Its "cost and efficiency" programme, first announced in November, "includes both headcount reductions as well as savings in external costs across the company's operations globally," a statement said.
"Today Ericsson is announcing that 2,200 positions in Sweden, mainly in R&D and supply, are subject to notice," the telecoms equipment maker said.
Ericsson employs nearly 120,000 people worldwide.
CEO Hans Vestberg told the TT news agency "there are two reasons (for the cuts), on the one hand a structural change in production and research and development, on the other, improvements in efficiency."
The group intends to make savings of some nine billion kronor (988 million euros, $1.05 billion, roughly Rs. 6,595 crores) through 2017, Wednesday's statement said.
In January, Ericsson said its net profit plunged 35 percent in the fourth quarter of 2014, dragged down by falling demand in its key market North America.
Profits slumped 35 percent to 447 million euros in the period, while net profit for the full year was down 4.0 percent to 11.57 billion kronor.
Late last year the group said it would refocus its business on its core network activities. Notably, it stopped developing modems, mainly for cell phones.
Wednesday's announcement deals a new blow to Sweden's technology sector two days after Sony Mobile announced 1,000 job cuts in the south of the country at a site once jointly operated with Ericsson.
