Abstract:
A mobile telecommunication system for transmitting a sound signal from a first terminal to a second terminal over two channels each comprising a predetermined number of bits, each of said first and second terminals being a mobile telecommunication terminal, said system comprising:a first base station to which said first terminal and a third terminal for transmitting a non-sound signal are connected; anda second base station connected to said first base station via a digital network, said second terminal being connected to said second base station, wherein said first terminal comprises:means for coding and compressing said sound signal to convert said sound signal into a compressed sound signal; andmeans for transmitting an answer signal in response to receiving a notice signal which informs that said second terminal is the mobile telecommunication terminal, andupon receiving said answer signal from said first terminal, said first base station transmits said compressed sound signal, which is transmitted from said first terminal, and said non-sound signal, which is transmitted from said third terminal, to said second bass station via said digital network by assigning said compressed sound signal to several bits of one channel of said two channels and several bits of the other channel of said two channels and assigning said non-sound signal to remaining bits of said one channel and remaining bits of said other channel.
