ABSTRACT:
This invention relates to the selection of a control channel in a mobile station, wherein a control data transmission is accomplished by a sequence of repeated control words. Having received a control word without error, the mobile station employs all or a portion of the remaining frame time to measure the signal strength of another control channel so as to enable a selection of a strongest control channel or to detect the availability of a digital control channel. In the preferred embodiment of the invention the mobile station receives at least one repeat of a control word from an analog control channel (ACC) and, if the repeat was received without error, tunes the receiver to receive another control channel, either another ACC from a neighboring cell, or a digital control channel (DCCH).
