摘要： A method for dividing a frame structure for a mobile telephone system which operates in half-duplex, i.e. in which the transmission and reception of signals in a mobile takes place within mutually separate time-slots (TS0 and TM0 respectively). Each frame includes three time-slots, each intended for transmission and reception. According to the method, the frame structure is divided so that transmission (TX) first takes place in a transmission time-slot (TS0). Reception (RX) then takes places in a reception time-slot (TM0) which is separate from the transmission time-slot (TS0). Subsequent to reception (RX), the frame structure includes an idle time (t.sub.1) which remains until further transmission (TX) takes place in the next-following frame. The method enables the frequency synthesizer (FM) of the mobile in the reception direction to be set to a channel (f.sub.x) different to the reception channel (f.sub.m) and then to be reset accurately to the reception channel (f.sub.m).
摘要翻译：一种用于划分半双工操作的移动电话系统的帧结构的方法，即移动站中的信号的发送和接收发生在相互独立的时隙（分别为TS0和TM0）内。每个帧包括三个时隙，每个时隙用于发送和接收。根据该方法，分割帧结构，使得首先在传输时隙（TS0）中进行传输（TX）。接收（RX）然后在与传输时隙（TS0）分离的接收时隙（TM0）中进行处理。在接收（RX）之后，帧结构包括保持直到在下一帧中发生进一步传输（TX）的空闲时间（t1）。该方法使移动台的接收方向的频率合成器（FM）能够被设定为与接收信道（fm）不同的信道（fx），然后被准确地复位到接收信道（fm）。

摘要： A method of reducing blockages and call interruption in handling over calls in a cellular mobile radio system. When the signal strength from a base station to a mobile and vice versa falls below a given value the handover shall take place to another base station. In order that the call will not be interrupted, a smaller number of channels are reserved, so-called rescue channels, from the ordinary channels in the system. The rescue channels can be fixed or dynamic for a given base station.

摘要： A synchronizing method in a mobile radio system which operates with Time Division Multiple Access (TDMA) but which lacks global time reference for all base stations and mobiles in the system. The inventive method is intended for ciphered transmission of data and speech in accordance with a given ciphering key (E2). When handing-over a call, the ciphering synchronism is lost. In accordance with the method, subsequent to hand-off (the time t.sub.2), the take-over base station (BS2) signals non-ciphered information (S1) to the mobile (MS) disclosing the number of frames (R1-R13) which shall pass until ciphering can again be commenced, calculated from a given frame (R1). Call information is transmit the following frame (R2), this information now being ciphered with the aid of a ciphering key (E1) different to the original key. This other ciphering key consists of a periodic bit sequence having a period which is equal to one frame interval.
