ABSTRACT:
A time-divisional duplex radio communication apparatus includes the steps of adding an interrupt enable signal to the compressed voice signal in place of the time-divisional synchronizing signal at a predetermined period in a radio communication apparatus served as a calling station, functioning the period corresponding to the time-divisional synchronizing signal as a reception period without having to add the time-divisional synchronizing signal to the compressed voice signal at the next transmission period if the interrupt enable signal from the calling station is received in a radio communication apparatus served as the called station, generating the interrupt request signal a predetermined time later than the reception of the interrupt enable signal of the calling station and transmitting the interrupt request signal in the reception periods of the calling station and the called station in a radio communication apparatus served as an interrupting station, indicating occurrence of an interrupt in response to the reception of the interrupt request signal in the radio communication apparatuses served as the calling station and the called station.
