Abstract

The invention relates to a method for maintaining a first data transmission connection from a terminal (MS) to a telecommunication network (NW1). In the method, at least a second data transmission connection is also set up between said terminal (MS) and telecommunication network (NW1). In the method, the first data transmission connection is interrupted for the time of the second data transmission connection. Furthermore, in the method, a message for maintaining the first data transmission connection is set up in the terminal (MS) in connection with setting up of the second data transmission connection. The generation of said message for maintaining the first data transmission connection is started in the terminal (MS).
