<p>A chat Short Message chat Service (SMS) among nicknames, whose cellular telephone numbers are masked, is provided with an IP server in separate non- communicating environments, also called real rooms. The server is connected both to a gateway to the mobile radio network and to a number of fixed terminals situated in respective real rooms forming a star-type intranet. For each real room the server provides a temporary code which authenticates the text messages sent in that real room to nicknames located in the same real room. The temporary authentication code is shown on a centrally situated display connected to the local terminal. Authentication is given following receipt of individual requests for enablement sent to the server by registered users of the chat service who include in their request message the temporary authentication code shown on the central display.</p> |
