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.

1. A method for supervising a dedicated control channel transmitted in a discontinuous transmission (DTX) mode to a mobile station, comprising:tracking a type of frame received in a transmission, wherein said frames comprise bad frames, good frames, and empty frames; counting the number of bad frames received (COUNT1), wherein COUNT1 is incremented if a bad frame is received, reset to zero if a good frame is received; disabling a mobile station transmitter if COUNT1 exceeds a first threshold (TH1); counting the number of good frames received (COUNT2), wherein COUNT2 is incremented if a good frame is received, and reset to zero if a bad frame is received; enabling said mobile station transmitter if COUNT2 exceeds a second threshold (TH2); setting a fade timer if COUNT2 exceeds a third threshold (TH3); disabling said mobile station transmitter and terminating said received transmission if said fade timer expires before COUNT1 is reset to zero; counting the number of empty frames received (COUNT3), wherein COUNT3 is incremented if an empty frame is received, and reset to zero if a good frame is received; disabling said mobile station transmitter if COUNT3 exceeds a fourth threshold (TH4); and terminating said received transmission if COUNT3 exceeds a fifth threshold (TH5), wherein TH5 is greater than TH4, or upon completion of said received transmission.
