ABSTRACT:
The invention relates to a method for improving the quality of control signalling based on signalling messages controlling speech or data transmission over an air interface between at least two radio terminals of a radio communications system, said speech or data being transmitted in at least one traffic channel of said radio communications system, and said signalling messages being transmitted in control channels associated with said at least one traffic channel. In order to allow for an improved performance of SACCH and FACCH, a first and a second signalling message with identical content are transmitted in two separate associated control channels. Alternatively, a signalling message included in a single ACCH is coded with a stronger coding. The invention relates equally to corresponding radio terminals and modules for such units.
