ABSTRACT:
Disclosed are a hybrid phone and a method of acquiring channels in the hybrid phone. The hybrid phone having a first communication mode supporting voice/low-rate data communications and a second communication mode supporting high-rate data communication includes a phone control unit having a communication processor controlling voice/data communications according to programs stored in a memory. The communication processor includes a channel acquisition processor attempting to acquire channels for the first and second communication modes. If the channel acquisition processor cannot acquire a channel for the second communication mode within a predetermined time, the channel acquisition processor stops attempting to acquire the channel for the second communication mode and reattempts to acquire channel for the first communication mode. If the channel acquisition processor acquires the channel for the first communication mode, the channel acquisition processor reattempts to acquire the channel for the second communication mode.
