Disclosed is a method for controlling a session in a server for controlling the session being performed between at least one first terminal and a remote end, the method including receiving a session discovery request message for acquiring information related to the session being performed between the at least one terminal and the remote end from a second terminal; checking whether or not the second terminal is permitted to acquire the information related to the session being performed by the first terminal; if permitted, checking which kind of media flows are contained in the session on the first terminal; checking whether or not there exists a media flow(s) to be masked or filtered among all the checked media flows, based upon information related to the masking from Inter-User Equipment (UE) Transfer (IUT) discovery configured for the first terminal; if there exists the media flow(s) to be masked or filtered among all the checked media flows, transmitting a session discovery response message including information related to the rest of one or more media flows except for the masked or filtered media flow(s) to the second terminal; receiving a transfer request message for a specific media flow(s) among the rest of one or more media flows from the second terminal; checking whether or not the session containing the media flow(s) requested to be transferred is a collaborative session, in response to the transfer request message received; forwarding the transfer request message to a controller terminal having the collaborative session control if the session is a collaborative session; and forwarding the transfer request message to the first terminal if the session is not a collaborative session. |
