Samsung and NEC have become the latest telcos to collaborate on developing new 5G services and products.
The vendors said in a statement that the partnership will bring together the companies' "best-in-class technology and expertise". They will build customised and region specific solutions that will meet operators' demands.
Atsuo Kawamura, EVP and President of the Network Services Business Unit at NEC Corporation, said: "5G development based on standardisation will help to accelerate business transformation throughout global markets.
"As 5G commercialisation is just around the corner, we are confident that the partnership with Samsung will continue to solidify our stance as a 5G leader."
Youngky Kim, President and Head of Networks Business at Samsung Electronics, said: "5G will unlock the potentials, create new values and push the limits of today's technology.
"We are excited to announce our joint efforts with NEC to boost 5G end-to-end solution portfolio for the best user experience."
Samsung has been busy pushing its 5G strategy forward with a wealth of new tests, acquisitions and plans.
Last week, it bought Spanish artificial intelligence and networks analytics firm Zhilabs, which it said would boost its automation solutions and underpin upcoming 5G products.
The Korean vendor announced over the summer that it would spend €150 billion to realign its business for the future and fund research into 5G, AI, autonomous driving and next generation semiconductors.
