Abstract
A method for universal mobile telephone service synchronization by a mobile station operating in a GSM dedicated mode in a wireless communication system including a mobile station sending voice signals to and receiving voice signals from a base station. A voice activity detector transmits control information indicating detection of voice activity at the mobile station, and an equalizer identifies and processes a training sequence and transmitting corresponding information for the training sequence. A physical layer interface determines whether the mobile station is utilizing discontinuous transmission mode, based on the control information from the voice activity detector, and determines whether the based station is utilizing discontinuous transmission mode, based on the correlation information from the equalizer, and universal mobile telephone service synchronization is performed in response to the mobile station and the base station utilizing discontinuous transmission mode.
