Förfarande och anordning i telekommunikationssystem

摘要

A user of a telephone service selects the quality level of a connection by manually specifying the desired quality level, automatically setting up the call with the specified quality level. To assist the user when selecting the quality, a voice sample of the user or a pre-recorded voice sample with specified quality levels may be played back to the user as a reference before the selection of a quality level. Alternatively, the user may be informed about transmission parameters associated with specified quality levels before the selection of a quality level. The method may be carried out by a service control point and a service switching point in a telecommunication network.
