Abstract： The advance of 5G technology can help to accelerate the development of remote applications in medical industry. Some telemedicine technologies are gradually improved, such as teleconsultation, remote diagnosis, remote ambulance, remote surgery and so on. As one of the main scenarios of 5G applications, 5G video services are required to achieve rapid transmission of high-resolution and high-frame-rate videos, as a result to optimize diagnostic results and improve medical efficiency. Virtual reality(VR) is a significant part of 5G video services, which is able to work with medical treatment to achieve functions like VR live broadcast in hospital, VR visit and so on. However, VR requires high capability of network, and the bandwidth and delay achieved by traditional 4G network cannot meet its requirements in medical application. This paper takes examples of VR visit and proposes a network solution to 5G medical applications based on SA smart medical private networks. Through Flex-E network slicing, edge computing and cloud application of VR, the medical resources are isolated from public resources to ensure the efficiency of VR data transmission, and a slicing scheme specific for VR scenarios is developed, which provides a fast and stable network solution for data transmission of VR applications in medical industry.
