Abstract

PURPOSE:To eliminate disturbance due to interference between radio waves sent from a calling station and a called station by giving a difference between the transmission patterns of on-hook signals that the calling and called stations send via a single radio circuit. CONSTITUTION:Even if radio waves including on-hook signals sent from a calling statin and a called station arrive at a base station at the same time, the radio waves never overlap each other for a constant time or longer without fail by making the pattern of radio-wave transmission differnt between the calling and called stations. Therefore, the fault that the on-hook signal is not received by the base station owing to radio-wave interference is solved.
