发明名称 Handover method for mobile radio system
摘要 The invention relates to a method in mobile radio systems in which the responsibility for transmitting message information to a mobile station (MS1, MS2) is handed over from at least a first base station transmitter (Bma, Bmb) to at least a second base station transmitter (Bna, Bnb). In accordance with the invention, the same radio channel is used, if possible, before and after the handover for transmitting message information to the mobile station. If the same radio channel can be utilized, the handover takes place without the mobile station being informed beforehand of the handover by a special signal or order or the like. In digital mobile radio systems with digital transmission of message information by digital modulation of the radio signals, the transmission is preferably started from a second base station transmitter before the transmission is terminated from a first base station transmitter. During a transmission time substantially the same message information is transmitted to the mobile station from both at least one first and one second base station transmitter.
