The invention discloses an intelligent home control system based on a 5G network and a network connection control method. The system comprises a 5G base station and at least two intelligent home clusters, wherein the 5G base station comprises a wireless resource management module, a cloud database and a database management module; each intelligent home cluster comprises all wireless intelligent home devices in one home; the wireless intelligent home devices are used for directly building wireless connection with the 5G base station and after the wireless connection is built, monitoring data are transmitted to the 5G base station; the wireless resource management module is used for allocating wireless resources for the wireless intelligent home devices; and the database management module is used for storing the monitoring data to the cloud database and managing the monitoring data in the cloud database. According to the intelligent home control system based on the 5G network and the network connection control method, the wireless intelligent home devices are directly connected to the 5G base station, and problems of complicated networking structure, long control signaling and long time delay in the existing intelligent home system can be solved.
