Slicing network routing method, apparatus and electronic device

Abstract

The application provides a slice network routing method and device and electronic equipment, and relates to the technical field of wireless communication. The slice network routing method comprises the following steps: a terminal device receives slice network information sent by a network device. Then, the terminal device establishes a routing table corresponding to each slice network according to the TD type corresponding to each slice network and the priority of each TD type. After detecting a network data packet to be routed, the terminal device can determine a target slice network corresponding to the network data packet according to the TD parameter carried by the network data packet and the routing table corresponding to each slice network, and route the network data packet to the target slice network. Through the technical solution, different network data packets can be routed to different slice networks by the terminal device.
