Device and method for controlling transmission on reverse link in mobile communication system

A mobile station device for resuming communication in a reverse link transmission suspended state in a mobile communication system, comprising:

• a measurer for detecting a power control bit from a channel signal received on a forward link channel and measuring a reception strength of the received channel signal using the detected power control bit;
• a controller for comparing the reception strength with a threshold and generating a signal for resuming transmission on a reverse link depending on the comparison;
• and
• a reverse link transmitter for resuming channel transmission on the reverse link in response to the transmission resuming signal;
• wherein the reception strength of the forward link channel output from the measurer is an SNR calculated using the power control bit.

A method of controlling communication on a reverse link for a mobile communication system, comprising the steps of:

• detecting a power control bit from a channel signal received on a forward link channel and measuring a reception strength of the received channel signal using the detected power control bit;
• comparing the reception strength with a threshold;
• and
• stopping transmission on a reverse link by controlling a reverse link channel if the reception strength is determined unacceptable as a result of the comparison;
• wherein the reception strength of the forward link channel output from the measurer is an SNR calculated using the power control bit.

A method of controlling communication on a reverse link in a mobile communication system, comprising the steps of:

• detecting a power control bit from a first channel signal received on a forward link channel and measuring a reception strength of the first channel signal using the detected power control bit;
• comparing the reception strength of the first channel signal with a first threshold and stopping transmission on a reverse link by controlling a reverse link channel depending on the comparison;
• detecting a power control bit from a subsequent channel signal received on the forward link channel and measuring a reception strength of the subsequent channel signal using the detected power control bit;
• comparing the reception strength of the subsequent channel signal with a second threshold and resuming transmission on the reverse link by controlling the reverse link channel depending on the comparison;
• wherein the reception strength of the forward link channel is an SNR calculated using the power control bit.
