Abstract

Method in a communication system using a logical control channel transmitting a control channel message, including handover information, between a mobile station 10 and a base station 26, in said system, using a first control channel modulation scheme. The method comprises the step of re-transmitting the control channel message using a second control channel modulation scheme, if the control channel message using the first control channel modulation scheme is not received or understood by the mobile station. According to a preferred embodiment the control channel is a Fast Associated Control Channel (FACCH).
