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;
transmitting, by the base station, a paging signal to the IoT device by using a first cycle according to the connection maintenance request, so as to confirm whether the IoT device is alive; and
when it is confirmed that the IoT device is alive, generating and transmitting, by the base station in substitution for the IoT device, a heartbeat packet carrying the identification code of the IoT device to the server by using a second cycle.
