摘要： Radio telephone apparatus for use in an underground railway system comprises two base stations (3, 4) respectively located at successive railway stations (1, 2). The base station (3) feeds a radiating cable (7) extending in the tunnel bore towards the base station (4) which feeds a radiating cable (12) extending in the tunnel bore towards the base station (3). When a train travels from the station (1) to the station (2), the mobile radio on the train effects call handover, i.e. transference of communication with cable (7) to communication with cable (12). To ensure no interruption in a call during handover, an attenuator (16) is incorporated in the cable (7) adjacent its end, such that the mobile radio effects call handover to the cable (12) before losing communication with the cable (7), even at the maximum possible speed of the train.

摘要： In process controlling computers, such as switching exchanges, faults may prove to be very expensive. Particularly hard to solve are software defects. If problems occur, it is important that maintenance can be directed at the correct target as soon as possible. A threat is constituted by vandals and hackers. If the option for maintaining from elsewhere is incorporated in computers, the danger for misuse consequently increases. Prior art techniques for detecting memory problems do not necessarily reveal defects occurring at regular intervals caused by the method of calculation. Memory defects will occur at regular intervals e.g., if an address line of a memory circuit becomes faulty. A second drawback of the prior art is that the checksum has to be calculated anew if the contents of just one storage location change. The method of detecting memory problems according to the invention is "regularly irregular" so that it detects in a reliable manner an uncontrolled change in any storage area (MA). Furthermore, the checksum (CS) calculated according to the method may be updated upon changes of an element in a storage area (MA) so that the updating requires much less calculation than would calculating the checksum over the entire storage area (MA) being monitored. The method is applicable in detecting hardware and software defects and in expediting the restart of a computer.
摘要翻译：在过程控制计算机（例如交换机交换机）中，故障可能被证明是非常昂贵的。特别难解决的是软件缺陷。如果发生问题，重要的是可以尽快将维护指向正确的目标。威胁是由破坏者和黑客组成的。如果从其他地方维护的选项被并入计算机，则误用的危险因此增加。用于检测存储器问题的现有技术不一定揭示由计算方法引起的以规则间隔发生的缺陷。存储器缺陷将以规则的间隔发生，例如，如果存储器电路的地址线变得有故障。现有技术的第二个缺点是如果只有一个存储位置的内容改变，那么必须重新计算校验和。根据本发明的检测存储器问题的方法是“规则地不规则”，以便以可靠的方式检测任何存储区域（MA）中的不受控制的改变。此外，根据方法计算的校验和（CS）可以在存储区域（MA）中的元素的改变时更新，使得更新需要的计算少于在被监视的整个存储区域（MA）上计算校验和。该方法适用于检测硬件和软件缺陷以及加快计算机的重新启动。

摘要： The invention relates to a handover method in a cellular radio system, and a cellular radio system. The cellular radio system comprises at least one subscriber terminal (101 and 102) and a base station (103 - 107), and in the system the subscriber terminal (101) maintains and continuously updates an active set of base stations (103 - 106), one or several base station (103 - 106) belonging to the active set having a connection or connection set-up facilities to the subscriber terminal. The subscriber terminal (101) controls the downlink transmission of one or several base stations (103 - 106) of the active set by switching the transmission of the base station on or off. This method provides a fast soft handover similar to the hard handover.

摘要： The invention relates to a receiving method in a digital cellular radio system. The invention further relates to a receiver of the cellular radio network. In computing the signal to noise ratio, a reference signal is utilized which is the convolution of the estimated impulse response of a channel and the predetermined sequence (53). The signal to noise ratio is obtained as a ratio between the variance of the reference signal and the predetermined sequence (53) received from the channel. The signal to noise ratio is used for weighting the diversity branches of the diversity receiver.

摘要： The invention relates to a method and system by means of which a large number of peripheral modules (TRn) can request service from a controller, e.g. in form of an interrupt request. Congestion of service requests is prevented in advance by assigning a predetermined time slot to each peripheral module (TRn) during which it is allowed to ask for service from the controller. The time slots are coordinated by a time slot counter which is stepped with a clock signal (CLK). The time slot counters of the different peripheral modules are synchronized with a synchronization signal (SYNC). The peripheral modules (TRn) may include subperipheral modules, whereby each subperipheral module can request service independently, or a gate N1 coupled to a register SR1 may be employed for detecting that a subperipheral module requires service.

摘要： The system described adapts packets of the fixed network directly to a DAB protocol packet channel. From the incoming packet stream, desired packets are separated by means of a receiving unit (63, 64, 65). An address and protocol converter (66) is used for separating packet addressing from the packet, and converting the addressing into the address of a mobile DAB receiver by using a conversion table. The converted address is transferred to the Data Group address field. Following this, DAB packets are made up from the Data Group in a manner known per se, and the converted address has also been transferred to the address field of the DAB packets. The packets are transferred to buffers (67) and further to the DAB system (B). The system is particularly well suited to adapting ATM cells and FR frames to the DAB system.

摘要： The invention relates to a method for providing delivery confirmations of message deliveries made in a telephone network (10). The method comprises the following steps: (a) a subscriber A provides a message addressed to a subscriber B, which message is temporarily stored in a storage device (14) located in the network, (b) an attempt is made for delivering the stored message to subscriber B, and (c) after the delivery attempts, subscriber A is delivered a confirmation of the result of the message delivery. In order that the confirmations can be provided as simply as possible from the subscriber's point of view, and causing a minimum load to the network, the network maintains subscriber-specific information on whether the subscriber has such a message delivery service available that allows delivery of subscriber-specific messages, whereby upon delivering a confirmation, it is possible to route a confirmation addressed to subscriber A to the message delivery service (15) on the basis of the information, if need be.

摘要： Many digital processors have an asynchronous bus controlled by two control signals (ENA', RWN). To interface a synchronous memory to an asynchronous bus, interface logic is required. In the interface (3) for transferring data (DATA) from an asynchronous circuit (1) to a synchronous circuit (2), data to be written are written in an intermediate register (DR) while the timing control signals (ENA', RWN) are being synchronized to the system clock (CKO) by means of flip-flops. Correspondingly, in the interface (4) for transferring data (DATA) from the synchronous circuit (2) to the asynchronous circuit (1), the signal (RWN) indicating a read transaction from the synchronous circuit is synchronized to the system clock by means of a flip-flop circuit.
