According to the present invention, a switching method and a switching device () are disclosed for providing a multilink connection between a subscriber () and a network (), the multilink connection consisting of a plurality of physical connections taken by the subscriber (). The switching device () comprises a plurality of converting means () each converting, upon activation, physical connections into a logical connection to the network () and converting a logical connection from the network () into physical connections. Furthermore, the switching device () comprises control means () for accepting a connection from the subscriber (), for detecting that the connection is a physical connection belonging to a multilink connection, for activating one of the converting means () for the detected multilink connection, and for directing the accepted connection and subsequently accepted physical connections belonging to the detected multilink connection to the converting means () activated for this multilink connection.

Effective multilink flow handling

The present invention relates to a method for establishing a telecommunication connection from a subscriber station (1, 9) of a radio system forming a wireless subscriber connection to a public switched telephone network (PSTN), in which method a call request is received from the subscriber station. For achieving a faster and simpler connection establishment than heretofore, a traffic channel is reserved from a data transfer channel (12) leading to the PSTN exchange (7) to be used by the subscriber station (1) that has sent a call request, a connection is established to the PSTN exchange (7), an acknowledgement message is sent to the subscriber station (1), and a speech path is connected between the PSTN exchange (7) and the user interface (2) of the subscriber station, whereby the sound signals fed by the PSTN exchange (7) are transmitted directly on the speech path to the user interface (2) of the subscriber station (1), and the diallings supplied from the user interface (2) of the subscriber station are transmitted to the PSTN exchange (7).
