  • Patent number: 9049254
    Abstract: The present invention discloses a control method, an apparatus, and a system. In the embodiments of the present invention, a control command is encapsulated into a network data packet to be sent to a remote network driver interface specification (RNDIS) device, and the encapsulated network data packet is sent to the RNDIS device to control the RNDIS device. In the conventional network architecture, a user device can directly send a network data packet to an RNDIS device. Therefore, with this solution, a control command can be transmitted to the RNDIS device without adding a new control interface. Compared with the solution that requires adding a new interface and installing an additional driver program in the prior art, this solution reduces application complexity and has no special requirement for the RNDIS device, which is commonly applicable and easy to implement.
