Following a data transmission the connection is released. Prior to setting-up of a connection between several communicating subscribers (30,36,40), a logic call is setup between them. For the logic a connectionless working transport mechanism is used. During an existing logic call its properties can be changed. By transmission of additional information, a call descriptor may be used for exchange of a logic call properties, which is transmitted for the logic call. The setting-up of a logic call and properties exchange are carried out separately. |
