Abstract
The present invention relates to a method and an apparatus in a mobile telecommunications system for the re-establishment of a speech connection, especially one that risks being interrupted prematurely. A parameter (Q) indicating the quality of the traffic channel (TCH) on which the speech connection is implemented, is compared to a predetermined value (Q,). If the parameter (Q) is lower than said value (Q,) the speech connection (,) is parked temporarily on a dedicated control channel (DCCH) of high quality. When a traffic channel (TCH) again becomes idle (,) the speech connection is handed over (,) to this channel, which may either be associated with the base station originally serving the speech connection or another base station in the mobile telecommunications system.
