1. A connection maintenance method for an Internet of Things (IoT) device, comprising:
establishing a virtual connection between the IoT device and a server;
receiving, by a base station, a connection maintenance request from the IoT device;
obtaining, by the base station, an identification code of the IoT device according to the connection maintenance request;
