The embodiment of the invention discloses a method for realizing remote media flow control which comprises the following steps that: a control point sends an SIP request message carried with an operating instruct message to a controlled point, and remotely indicates a session operation and/or a media flow operation needed to be executed by the controlled point; after the controlled point receives the SIP request message, the controlled point executes the corresponding session operation and/or media flow operation according to the operating instruct message. With the method of the embodiment of the invention, the operation of appointed medial flows that the control point directly controls the controlled point can be realized. Further, an operating instruct for a plurality of sessions and corresponding media flows can be carried in the operating instruct message, so the aim of remote control of a plurality of sessions in an SIP request can be realized. The embodiment of the invention also discloses a communication system, control point equipment and controlled point equipment for realizing remote media flow control.
