Research on 5G Dual Domain Private Network Scheme Based on UPF Diversion Technology

With the evolution of 5G mobile communication technology and network construction, vertical industries such as government, education, culture and tourism, and industry are showing an increasing demand for seamless access to both customer intranets and the internet. This paper studies two types of dual domain private network solutions for 5GToB/ToC, fixed area and wide area roaming based on UPF diversion technology. In order to solve the problems of terminal restrictions and data routing detours, a dual domain private network solution based on dedicated DNN+intelligent diversion UPF is further proposed, which achieves the goal of 5G industry customers not leaving the park with data. The new requirement of “seamless access to office intranet servers and the internet without changing cards, numbers, and perception switching” is proposed based on dedicated network slicing, achieving flexible office work.
