Traditional pre-hospital first-aid and emergency medical services face challenges such as long waiting time for patients and delayed information exchange. By leveraging the innovative application of 5G+SPN private network technology, which integrates heterogeneous networks and multi-source data through "one network for unified management", shortens emergency response time through "one-key assembly" and "one-stop treatment", ensures data security and patient privacy through the "5G private network escort", a new model of pre-hospital first-aid and emergency medical service was built. In practice, Guangzhou Emergency Medical Command Center has built an information system for emergency medical service, Guangzhou Red Cross Hospital and the Second Affiliated Hospital of Guangzhou Medical University have developed an emergency green channel based on the Internet of Things, and China Mobile Guangzhou Branch has achieved the integration of fixed and mobile networks, which have further enhanced the capacity of delivering pre-hospital emergency medical treatment and responding to medical emergencies.
