HELSINKI, Finland (AP) _ Third-quarter profits rose 36 percent at Nokia OY as demand for the company's mobile phones drove a 49 percent jump in sales.

The Finnish company earned 638 million euros ($686 million), or 0.56 euros a share, an increase from 464 million euros, or O.41 euros a share, in the same period last year.

Third-quarter sales totaled 5.04 billion euros ($5.35 billion), up from 3.38 billion euros a year earlier.

Mobile phone sales rose 58 percent to 3.44 billion euros, while the network equipment unit generated revenues of 1.44 billion euros, up 38.5 percent from the third quarter of 1998.

Chief executive Jorma Ollila predicted that sales for the whole year will increase by more than 40 percent at Nokia, the world's top supplier of wireless phones.

``Our performance in the third quarter gives us every reason to be satisfied. We launched numerous products and solutions, and made several changes to our structure,'' Ollila said.

For the first nine months of 1999, Nokia's net profit totaled 1.72 billion euros or 1.50 euros per share, up from 1.10 billion euros or 0.96 euros in the same period last year.

Nine-month sales grew to 13.4 billion euros from 8.9 billion euros for the same period in 1998.
