Abstract
A radio link switching scheme in which a communication between the base station and the mobile station is carried out through the radio link given in terms of frames while providing a switching timing information formed by a layer 1 bit data in each frame of the radio link such as a unique word, a flag, a housekeeping bit, and a frame number. Then, the switching timing information in at least one of the frames of the radio link at the base station is changed to indicate a switching of the radio link whenever a need for switching the radio link between the base station and the mobile station arises, and transmitted to the mobile station. At the base station, the radio link is switched at a switching timing which is a prescribed period of time after each frame in which the switching timing information is changed, while at the mobile station the radio link is switched at a switching timing which is a predetermined period of time after each frame in which the changed switching timing information is detected.
