Device mapping method,control terminal and controlled terminal

The invention relates to the field of communication, and provides a device mapping method, a control terminal and a controlled terminal. The method comprises the following steps: the controlled terminal sends a device enumeration request message to the control terminal through an RCP (Remote Control Protocol) data message; the response message, including a supportive device type list, sent by the control terminal, is received by the controlled terminal; according to the supportive device type list, the controlled terminal generates a virtual device corresponding to a device type in the supportive device type list; a device data request message is sent by the controlled terminal through the RCP data message; the response message, sent by the control terminal and including device data generated by a to-be-mapped device of the control terminal, is received by the controlled terminal; and the controlled terminal provides the device data for the virtual device and provides for the upper application via the virtual device. According to the method, the control terminal and the controlled terminal, a certain device on the control terminal can be mapped on the controlled terminal, and the mapped device serves as the control terminal's own device for use, so the method has the advantage of universality.
