There are a lot of researches related to SDN in 5G networks. You can see those they may help

Dear Sathyaprakash Palaniappan,

attached you have my literature sources. These illustrate some use cases of SDN in 5G mobile networks.

Best regards

Dear Anatol Badach ,

i am happy to see your suggestion , i will go through it .

Dear Sathyaprakash Palaniappan,

in my previous answer, I forgot to mention the concept of Network Slicing. With the help of Network Slicing, private, virtual 5G networks can be set up. SDN plays the fundamental role. I have added some literature sources about Network Slicing.

Best regards

Dear Anatol Badach ,

Thank you so much for your concern .

Actually im stepping into sdn technology as a fresher , but your support and suggestions were supportive to land in the concept properly
