Abstract
An optional short SACCH is used when the network detects high error rate in the normal SACCH channel. The communication returns to normal mode when the network detects that the link quality has improved. In the short SACCH message only the most relevant information fields are sent. The extra bits are used for channel coding so that in the channel conditions where the most robust AMR codings still work, the BLER of short SACCH is still tolerable.
