摘要： Methods for carrying out an authentication check in a mobile telephone system in which an authentic base station serves a plurality of mobile stations. A prior method carried out a unidirectional check from the base to a calling mobile, permitting a false base to carry out a false authentication check by collecting a number of so-called RAND-Response pairs. To avoid this problem, another unidirectional, base-to-mobile, authentication check and an authentication check from the mobile to the base are carded out. In one embodiment, only the bi-directional authentication check is carried out.

摘要： In a receiving circuit of a mobile telephone apparatus the incoming baseband signals are demodulated and equalized so as to compensate for deficiencies (multipath propagation) of the radio medium between base station and mobile telephone apparatus. It is not, however, always necessary to equalize the demodulated signals, for instance at low symbol rates or in the case of monopath propagation. According to the invention, time dispersion of the received signals is estimated prior to demodulation, and demodulation with equalization (3a) is effected when the time dispersion is established to be higher than a given value, whereas demodulation without equalization (3b) is effected when the time dispersion is lower than this value. This will enable the power consumed by the receiving circuit to be reduced, particularly in the listening mode of the apparatus.

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.
摘要翻译：一种在蜂窝移动无线电系统中处理呼叫时减少阻塞和呼叫中断的方法。当从基站到移动台的信号强度反之亦然降低到给定值以下时，将切换到另一个基站。为了不会中断呼叫，从系统中的普通信道保留较少数量的信道，即所谓的救援信道。对于给定的基站，救援通道可以是固定的或动态的。

摘要： A method is disclosed for improving the efficiency of the packet data channel by interrupting transmissions from or to a first mobile station so as to allow a short message to be communicated between the communication system and a different mobile station. The packet channel feedback information includes several flags: Received/Not Received (R/N); Partial Echo (PE); and Partial Echo Qualifier (PEQ). The PEQ allows the communication system to interrupt the transmission to one mobile station to send a short message to another mobile station. By setting the PEQ to various values, a mobile station can determine whether subchannel ownership has been temporarily interrupted and reassigned to another station.

摘要： A method and apparatus for performing over-the-air activation for wireless communications service subscriptions within a wireless communications system. The method includes providing a plurality of subscription modules each having a unique identifier that corresponds to a plurality of non-activated service subscriptions. An activation period is established for each of the non-activated service subscriptions within which the corresponding subscriptions must be activated or deleted from the system. A list of unique identifiers and their associated activation periods is stored in the wireless communications system. To activate the subscription, a subscription module is mated with a mobile equipment device. An over-the-air activation request is transmitted to the wireless communications system that includes the unique identifier associated with said selected subscription module. The service subscription associated with the unique identifier is activated when the unique identifier is stored on the list and the activation period is valid.

摘要： The invention relates to a method in mobile radio systems in which the responsibility for transmitting message information to a mobile station is handed over from a first base station transmitter to a second base station transmitter. In this method, 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 ratio 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 certain transmission time substantially the same message information is transmitted to the mobile station from both the first and second base station transmitters.

摘要： The invention relates to a method in mobile radio systems in which the responsibility for transmitting message information to a mobile station (MS.sub.1, MS.sub.2) is handed over from at least a first base station transmitter (B.sub.ma, B.sub.mb) to at least a second base station transmitter (B.sub.na, B.sub.nb). 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.

摘要： The invention relates to a cellular digital mobile radio system including base stations (B.sub.m, B.sub.n) and mobile stations (MS.sub.1, MS.sub.2) 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 (B.sub.ma, B.sub.mb, B.sub.na, B.sub.nb) at a given transmitting distance from each other are assigned to each of certain cells (C.sub.m, C.sub.n) 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.
