Setting up a conference call between members of a chat group

摘要

The invention relates to a method of setting up conference calling in a communications system. In the method, at least one subscriber group having two or more subscribers is established in a server connected to the communications system; subscribers registered in the set up group chat with each other by messages in such a manner that the server in the communications system receives a message of a subscriber participating in the message chat and transmits it on to other subscribers belonging to the group in question. In the method, it is also possible to move from message chatting to conference calling by one of the subscribers in the subscriber group sending a pre-defined message to the server, which message acts as a signal to the server to move to conference calling; the server sets up a conference call between the subscribers registered as active in the subscriber group in response to receiving said pre-defined message.
