Method for establishing a communication connection and telecommunications system for implementing the method

摘要

The method involves exchanging a start message and acknowledgement messages between a calling communication terminal (4), another communication terminal (6) and a supervisory communication-management module (2). A connection-initiation sequence is provided for agreement of connection modalities relevant to the terminal (6) between the module (2) and an application management module (10) of the terminal (6). A signaling element with control information for the connection-initiation sequence is added with an acknowledgment message outputted from the terminal (4) to the module (2).
