The TC sends media stream transmission information of the TC to the media gateway through a virtual machine (VM), and receives media stream information of the media gateway from the VM. A session between the TC and the media gateway is established. After the session is established, the TC and the media gateway transmit media stream data directly by taste the established session. ## Claims ### Claim 1 A method for transmitting media stream data in a cloud computing system, comprising: sending, by a thin client (TC), media stream transmission information of the TC to a virtual machine (VM), the cloud computing system comprising a physical server on which the VM runs, the TC being used for logging in to the VM, and the TC and the VM communicating through remote desktop protocol;
