A method, device, and system for establishing a multi-user service, and a method, device, and system for transferring a control channel are provided. The method for establishing the multi-user service includes the following steps. A media control channel parameter and a media transmission channel parameter are returned according to a received media session establishing request. An associated parameter is received, in which the associated parameter is a parameter generated by associating the media control channel parameter of a controlling-party user unit with the media transmission channel parameter of a receiving-party user unit. A media control channel is established with the controlling-party user unit according to the associated parameter. A media transmission channel is established with the receiving-party user unit according to the associated parameter. The media control channel parameter of a controlling party and the media transmission channel parameter of a receiving party are sent to a network side by initiating a third-party call and the multi-user service is established. Therefore, disadvantages in the prior art are overcome, user experience is improved, and functions of the multi-user service are enriched.
