    摘要： The invention concerns a method and a device for phase calculation from attenuation values using a Hilbert transform for reflectometric measurements in the frequency domain. The invention is characterized in that the measuring system comprises a signal source for a measurement signal, a coupling element connected to the signal source, and an object to be measured connected to the coupling element. The part of the measurement signal reflected by the object to be measured is uncoupled via the coupling element and measured at a collector. The invention is further characterized in that an attenuator is mounted in the signal path, between the coupling element and the object to be measured. The attenuator can also be comprised in the coupling element.

    摘要： The invention relates to a method for automatically controlling paths of information of all types at a data-receiving location. The aim of the invention is to enable any type of information, which is transmitted from a transmitter to a receiver, to be specifically assigned to a processing location or to another provided location in order to undergo subsequent processing. To this end, the data-receiving location provides a data-transmitting location with special input channels serving as entry-point address identifiers (EAK) that, at the receiver and during data input, control, like a code, the procedure in handling the information.

    摘要： The invention relates to a method for the mutual authentication of components in a network by means of the challenge-response method, according to which the network (N) requests a set of three data values (challenge 1/ response 1/ response 2) from an authentication centre (AUC) and transmits at least one set of data values (challenge 1) to the mobile station (M) which on the basis of an internally stored key (Ki) calculates a response 1 from this set of data values and transmit it to the network (N). To authenticate the network (N) in relation to the mobile station (M) the invention provides for the response 1 sent back to the network (N) to be interpreted simultaneously by said network (N) as challenge 2 and for said network (N) immediately to transmit a response 2 to the mobile station (M). This improves and accelerates data traffic between the mobile station and the network because there is no transmission of challenge 2 between the mobile station and the network. Data traffic between the network and the AUC is also improved because the data pairs challenge 2 and response 2 no longer have to be calculated separately in the AUC and transmitted to the network.

    摘要： The invention relates to a method for carrying out a blind handover in an intersystem and interfrequency handover in mobile communication systems, whereby a mobile station is supplied by several base stations prior to the handover i.e. it can receive several other base stations in addition to the supplying base station. According to the invention, measurement of the propagation time of the signals received from the base station is carried out by the mobile station on the air interface. The measured propagation times are transmitted to one of the base stations. The location of the mobile station is determined using the transmitted propagation time measuring data by the mobile communication network. With the aid of a data base, at least one suitable base station for an intersystem or interfrequency handover is then selected using the determined location and the data necessary for a handover is transmitted to the mobile station from the selected base station. The mobile station can carry out the handover to the selected base station using said information.
