implementing network attachment after turned on;

implementing network attachment after returning to a coverage area of a cellular network from a coverage hole of the cellular network; or

implementing network attachment after plugged with a Subscriber Identification Module (SIM) card.

4. The method of claim 1 , wherein a correspondence between the TAC and the type of the UAV satisfies: TAC1 corresponding to the micro UAV, TAC2 corresponding to the light UAV, TAC3 corresponding to the small UAV, TAC4 corresponding to the medium-sized UAV, and TAC5 corresponding to the large UAV.

5. An information transmission method, comprising:

sending, by a mobility management entity (MME), an identity request to an unmanned aerial vehicle (UAV) in a network attachment process;

receiving, by the MME, an identity response comprising type information sent by the UAV, wherein the type information indicates a type of the UAV;

determining, by the MME, a supervision requirement according to the type of the UAV; and

controlling, by the MME, the UAV through the supervision requirement, wherein the supervision requirement comprises alarming or decreasing a flight height, the type information is an International Mobile Equipment Identity (IMEI) of the UAV, the IMEI comprises a Type Allocation Code (TAC) used for indicating the type of the UAV, and the type of UAV comprises at least one of: a micro UAV, a light UAV, a small UAV, a medium-sized UAV or a large UAV.

6. The method of claim 5 , wherein the UAV accesses a cellular network through the network attachment process.
