    • The invention relates to a cellular digital mobile radio system including base stations (Bm, Bn) and mobile stations (MS1, MS2) with transmitters and receivers. The invention also relates to a method of transmitting message information digitally between mobile and base stations in such a system. In accordance with the invention, at least two base station transmitters (Bma, Bmb, Pna, Bnb) at a given transmitting distance from each other are assigned to each of certain cells (Cm, Cn) within a restricted geographical area. The base station transmitters which are assigned to the same cell transmit digitally modulated radio signals within the same frequency range at least partially simultaneously to the mobile stations of the cell. The radio signals from different base station transmitters associated with the same cell are digitally modulated with the same message information to the mobile stations in the cell. Different base station transmitters (9A, 9B) preferably transmit the digitally modulated radio signals with the same message information to a given mobile station with a given mutual transmission time shift. Here, the transmission time shift is selected individually for each mobile station, such that corresponding digitally modulated radio signals with the same message information to a given mobile station from different base station transmitters arrive practically simultaneously at the mobile station.
    • 本发明涉及包括基站(Bm,Bn)和具有发射机和接收机的移动台(MS1,MS2)的蜂窝数字移动无线电系统。 本发明还涉及在这种系统中在移动台和基站之间数字地发送消息信息的方法。 根据本发明,在给定的彼此的发送距离处的至少两个基站发射机(Bma,Bmb,Pna,Bnb)被分配给受限地理区域内的某些小区(Cm,Cn)中的每一个。 分配给相同小区的基站发射机至少部分地同时向小区的移动台发送在相同频率范围内的数字调制无线电信号。 来自与相同小区相关联的不同基站发射机的无线电信号用相同的消息信息被数字调制到小区中的移动台。 不同的基站发射机(9A,9B)优选地以给定的相互传输时间偏移将具有相同消息信息的数字调制无线电信号发送给给定的移动台。 这里,对于每个移动台单独选择传输时移,使得具有相同消息信息的相应的数字调制无线电信号从不同的基站发射机到给定的移动台在移动台实际上同时到达。

    • A method in a mobile radio station to select one of a number of dedicated control channels (DCCH1-21) which are transmitted from a number of base stations (B1-B21) in a mobile radio system. In the mobile station there is an equalizer to compensate for the multipath propagation characteristics of the radio medium between the mobile station and a certain base station. This equalizer is power consuming and should not be used if not necessary. According to the method an investigation is carried out in the mobile station whether or not the equalizer can be disconnected during the initialization of a call from the mobile to a base station. The signal quality of the dedicated channel (DCCH1) which has the greatest signal strength is measured without the equalizer. If the signal quality is not acceptable, a new detection is made with the use of the equalizer. If the signal quality then is acceptable another detection is made without equalizer on the dedicated control channel (DCCH2) which has the next strongest signal and if this detection revealed an acceptable signal quality the base station (B2) transmitting this control channel is selected by the mobile station for the further call progress.
    • 一种移动无线站中的方法,用于选择在移动无线电系统中从多个基站(B1-B21)发送的多个专用控制信道(DCCH1-21)中的一个。 在移动台中,存在用于补偿移动台与某个基站之间的无线介质的多径传播特性的均衡器。 该均衡器是耗电量,如果不需要,不应该使用。 根据该方法,在从移动台到基站的呼叫初始化期间,在移动站中进行调查是否可以断开均衡器。 在没有均衡器的情况下测量具有最大信号强度的专用信道(DCCH1)的信号质量。 如果信号质量不可接受,则使用均衡器进行新的检测。 如果信号质量可以接受,则在没有均衡器的情况下,在具有下一个最强信号的专用控制信道(DCCH2)上进行另一个检测,并且如果该检测显示可接受的信号质量,那么发送该控制信道的基站(B2)由 移动台进一步呼叫进度。

    • A method in a mobile radiotelephone system in which an address is added to a symbol message in a control channel in order to exclude interfering connections operating on the same radio frequency as the actual connection between a base station and a mobile station. According to the proposed method, the address (A1) to the intended receiver is added to the message (M) and an error check word (E) is calculated based on both the address (A1) and the message (M). Before transmitting to the receiver, the added address is removed and the transmitted control signal includes only the symbol message (M) and the error check code (E). In the receiver, the specific address for the receiver is added to the received control signal and the same calculation is carried out as in the transmitter in order to get an accept/reject signal.
    • 一种移动无线电话系统中的方法,其中将地址添加到控制信道中的符号消息,以便排除与基站和移动站之间的实际连接在相同射频上操作的干扰连接。 根据所提出的方法,将预期接收机的地址(A1)添加到消息(M)中,并且基于地址(A1)和消息(M)两者计算错误校验字(E)。 在发送到接收机之前,删除添加的地址,并且发送的控制信号仅包括符号消息(M)和错误校验码(E)。 在接收机中,接收机的特定地址被加到接收到的控制信号上,并且像发射机那样执行相同的计算,以获得接收/拒绝信号。
