A method for controlling a teleconference, wherein at least one participant is not located in the conference environment, with the steps: a) logging on of mobile terminals (191-196) by participants (151-159) who are in the same conference environment for the participants (151-159), b) determining the resources made available by each mobile terminal (191-196), wherein the determination comprises a presence, type and properties of cameras (d), loudspeakers (b), microphones (a), monitors (c) and battery charge of the mobile terminal (191-196); and d) actuating loudspeakers (b) of the mobile terminals (191-196), in such a manner that the loudspeakers of multiple or of all the logged on mobile terminals (191-196) are combined to form an audio system, in order to output acoustic conference information of the at least one remote conference participant who is not located in the conference environment, for the purpose of a surround sound procedure in the conference environment , wherein, depending on the spatial arrangement of the mobile terminals (191-196) for the purpose of the surround sound procedure, the acoustic conference information is distributed over the loudspeakers of the mobile terminals (191-196), e) actuating microphones (a) of the mobile terminals (191-196), in order to create a three-dimensional microphone field, so that, for the at least one remote conference participant who is not located in the conference environment, a surround sound of the conference information received by the microphones is provided, wherein the method is carried out by a Local Media Control Unit, LMC, wherein, depending on the available computation power of the LMC and the proximity of the logged on mobile terminals with respect to one another, individual or multiple mobile terminals, during the generation of the surround sound and/or of the 3D microphone field, can be excluded with regard to the inclusion of the resources of these individual or multiple mobile terminals, wherein, during the reception of a call on a mobile terminal, the resources thereof are released by the LMC and shifted to the closest other mobile terminal by use of the resources thereof. a) logging on of mobile terminals (191-196) by participants (151-159) who are in the same conference environment for the participants (151-159), b) determining the resources made available by each mobile terminal (191-196), wherein the determination comprises a presence, type and properties of cameras (d), loudspeakers (b), microphones (a), monitors (c) and battery charge of the mobile terminal (191-196); and d) actuating loudspeakers (b) of the mobile terminals (191-196), in such a manner that the loudspeakers of multiple or of all the logged on mobile terminals (191-196) are combined to form an audio system, in order to output acoustic conference information of the at least one remote conference participant who is not located in the conference environment, for the purpose of a surround sound procedure in the conference environment , wherein, depending on the spatial arrangement of the mobile terminals (191-196) for the purpose of the surround sound procedure, the acoustic conference information is distributed over the loudspeakers of the mobile terminals (191-196), e) actuating microphones (a) of the mobile terminals (191-196), in order to create a three-dimensional microphone field, so that, for the at least one remote conference participant who is not located in the conference environment, a surround sound of the conference information received by the microphones is provided, <EOS>
