What is claimed is: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. 2. The method for rejoining the network according to claim 1 , wherein the step of determining to disconnect network connection with the target mobile terminal comprises:determining whether the heartbeat frame of the target mobile terminal is received within a predetermined time interval. 3. The method for rejoining the network according to claim 1 , wherein the step of sending the supplementary broadcast frame comprises:sending the supplementary broadcast frame in an idle time slot of the gateway device. 4. The method according to claim 1 , wherein the step of sending the supplementary broadcast frame comprises:sending the supplementary broadcast frame in an idle time slot. 5. A method for rejoining a network after network disconnection of a mobile terminal, applied to a server, comprising:receiving, by the server, network disconnection information of a target mobile terminal of a gateway device fed back by the gateway device; and sending a supplementary broadcast frame instruction to the gateway device and at least one other gateway device within a first preset distance range relative to the gateway device, wherein the first preset distance range is a range defined by taking the gateway device as a center and a first distance as a radius; wherein the method further comprises: receiving locating information fed back by the target mobile terminal; and determining a movement track of the target mobile terminal according to the locating information fed back by the target mobile terminal and received within a predetermined time length range from a current time node; sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range relative to the gateway device comprises: determining a predicted movement direction of the target mobile terminal according to the movement track; and sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range and in the predicted movement direction relative to the gateway device. 6. The method for rejoining the network according to claim 5 , further comprising:sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range relative to the gateway device comprises: determining a second preset distance range according to the locating information, wherein the second preset distance range is a range defined by taking a positioned location in the locating information as a center and a second distance as a radius; and sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range and the second preset distance range. 7. The method for rejoining the network according to claim 6 , further comprising:determining locating information fed back by the target mobile terminal last time; sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range relative to the gateway device comprises: determining the second preset distance range according to the locating information fed back by the target mobile terminal last time, wherein the second preset distance range is a range defined by taking a positioned location in the locating information fed back last time as a center and the second distance as a radius; and sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range and the second preset distance range. 8. A method for rejoining a network after network disconnection of a mobile terminal, applied to the mobile terminal, comprising:determining whether to disconnect network connection with a gateway device; when it is determined to disconnect the network connection with the gateway device, receiving a supplementary broadcast frame sent by the gateway device after the disconnection from the gateway device or a supplementary broadcast frame sent by other gateway device; and establishing a connection with the gateway device or other gateway device according to the supplementary broadcast frame; wherein the method further comprises: sending a heartbeat frame to the gateway device; and determining whether to disconnect network connection with the gateway device comprises: determining whether a response message from the gateway device for the heartbeat frame is received; wherein a time difference between disconnecting from the gateway device and receiving the supplementary broadcast frame is less than twice a cycle that the mobile terminal sends the heartbeat frame. 9. The method for rejoining the network according to claim 8 , further comprising:feeding back locating information of the mobile terminal to a server. 10. A gateway device, comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to execute the method according to claim 1 . 11. A server, comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to execute the method according to claim 5 . 12. A mobile terminal, comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to execute the method according to claim 8 . 13. An electronic device, comprising a memory, a processor, and a computer program stored on the memory and runnable on the processor, wherein the processor implements the method according to claim 1 when executing the computer program.
