As 5G private networks are characterized by low latency, high bandwidth and massive connections, they can be applied to various industries such as medical and health care, power networks, logistics and storage to improve network capabilities. In order to meet the low-latency and high-reliability requirements of 5G private network, a fusion architecture combining 5G private network and time sensitive network(TSN) is proposed. With the help of salient technologies in TSN, such as the traffic scheduling and traffic shaping, network bandwidth reservation and precise clock synchronization, they can meet the low-latency and high-reliability requirements of fusing 5G private network and TSN. Furthermore, through studying the key technologies of fusing 5G private network and TSN, such as traffic mapping and scheduling and collaborative management technologies, the fusion process of the two networks can be accelerated in industrial Internet scenarios. Finally, the challenges of the fusion of 5G private network and TSN are discussed, and the development ideas for the fusion architecture and key technologies are provided.
