Abstract
A method for transmitting a call signal through a digital channel while in an analog area is provided which allows for enhanced speech and transmission quality while in the analog area. When a call is originated in an analog area, a mobile communication terminal scans a most recently used (MRU) table to locate a digital channel which matches a digital channel available in the analog area. If there is a match, the call is placed through the available digital channel. If none of the digital channels in the MRU table matches the available digital channel, then the call is placed through an analog channel.
