Title: Mobile station supervision of the forward dedicated control channel when in the discontinuous transmission mode

Abstract: A method and apparatus for supervising a dedicated control channel when in the discontinuous transmission mode. The mobile station monitors the frames it receives from a base station and maintains a counter of bad, good, and empty frames, referred to as COUNT1, COUNT2, COUNT3, respectively. If a received frame is a good frame, COUNT1 is reset to zero and COUNT2 is incremented. If the received frame is a bad frame, COUNT1 is incremented and COUNT2 is reset to zero. If the received frame is an empty frame, COUNT1 and COUNT2 are unchanged but COUNT3 is incremented. A transmitter coupled to the mobile station is enabled or disabled depending upon which, if any, of the COUNTs reaches or exceeds a designated threshold value. In another embodiment, an average aggregated value reflecting the strength of the pilot signals in an active set, measured at the mobile station, is used for comparison to a threshold.
