Abstract: Disclosed is a method which allows for a fast and efficient establishment of a connection between members of a group, more specifically between a mobile radio user who triggers the establishment of the connection and additional mobile radio users of a group of mobile radio users via at least one mobile radio network. According to the inventive method, a first channel that can be used for transmitting signaling data is set up when establishing the connection. User data, such as language, which is to be transmitted between the mobile radio user triggering the establishment of the connection and other members of the group is also transmitted via said channel in addition to the signaling data until a second channel is also set up for the connection, whereupon user data is transmitted via the second channel.
