Telecommunication company network equipment maker Nokia and Chinese smartphone maker Xiaomi Technology have signed a patent licensing agreement, the companies said on Wednesday.

 The companies did not provide financial details of the agreement, saying it includes a cross license to each company's cellular standard patents.
Nokia will also provide network infrastructure equipment to Xiaomi.

"Xiaomi is one of the world's leading smartphone manufacturers and we are delighted to have reached an agreement with them," Nokia Chief Executive Rajeev Suri said in a statement.

Nokia has license deals with leading handset makers Apple and Samsung Electronics, but the agreement with Xiaomi is the Finnish company's first with a Chinese phone maker.

"Financially, I don't think it's very substantial for Nokia. But it's a good head start to negotiations with other Chinese manufacturers", said OP Equities analyst Hannu Rauhala.

Patent royalties represent a sliver of Nokia's overall revenue, more than 90 percent of which comes from telecoms network equipment. But licensing payments are highly profitable and the network business is suffering an industry-wide slump.
