1. A method for rejoining a network after network disconnection of a mobile terminal, applied to a gateway device, comprising steps of:
determining whether to disconnect network connection with a target mobile terminal; and
sending a supplementary broadcast frame when the gateway device is disconnected from the target mobile terminal;
wherein the method further comprises:
feeding back network disconnection information of the target mobile terminal to a server when the connection between the gateway device and the target mobile terminal is disconnected;
receiving a supplementary broadcast frame instruction fed back by the server; and
sending the supplementary broadcast frame according to the supplementary broadcast frame instruction;
wherein a time difference between feeding back the network disconnection information and sending the supplementary broadcast frame is less than a cycle that the target mobile terminal sends a heartbeat frame.
