Abstract: A method controls a radio cell monitoring system. A standardized radio cell list is transmitted by a device on the network side, the device being allocated to a radio cell of interest. The radio cell list lists radio cells that are adjacent to the radio cell of interest, receiving radio communication terminals monitoring, using the radio cellist, the signals of the adjacent radio cells for a handover or a cell reselection by way of measurement. The respective measurements of the radio communication terminals are transmitted to the device on the network end. At least one priority on the network side is allocated to each radio cell of the radio cell list. Additionally, at least one indication on the network side, indicating which services are offered within the respective radio cell for execution, is allocated to every radio cell of the radio cell list.

Abstract: Interference is reduced between two radio communication systems. A first radio communication system uses a first and a second frequency ranges which are separated by a duplex gap. A second radio communication system uses a third radio frequency range which forms part of the duplex gap. The first and second radio communication systems exchange information in order to establish an a priori knowledge about a connection on the network side. The a priori knowledge includes the radio transmission resources of the first frequency range provided on the radio communication system side and of the second frequency range and the radio transmission resources of the third frequency range (FB3) desired for call setup and completion. Radio transmission resources are selected depending on the a priori knowledge at the second radio communication system in order to reduce interferences between the first and second radio communication systems.

Abstract: In a wireless communication system having at least first and second radio stations located at a network end and connected to a core network, the first radio station receives a registration message from a user station to initially register the user station in a radio station located at the network end, after the user station has been switched on. Subsequently, communication takes place between the core network and the user station. Signaling messages that are to be sent from the core network to the user station are transmitted, at least at the beginning of the communication between the core network and the user station, from the core network to the second radio station, then from the second radio station to the first radio station or another radio station located at the network end, and from the first radio station (or the other radio station) directly to the user station.

Abstract: To transfer intersystem connections, the quality of a transfer to a supplying base station in a first radiocommunication system is determined at a given moment by a subscriber station and compared to a threshold value. If the value falls below said threshold, a compressed mode is activated and measurements are carried out by the subscriber station in relation to the transfer qualities to neighboring base stations in a second radiocommunication network. On the basis of said measurements, the subscriber station selects a base station for the transfer of a connection. If the value falls below the second threshold, information sequences in the organization channels of the selected base stations are detected by the subscriber station.

Abstract: A method detects which radio communication terminals use interference suppression procedures, in a radio communication system. Here radio communication terminals periodically return measurement signals which represent radio field characteristics and/or reception situations determined at the radio terminal to a base station and compare these signals with one another and also with threshold values determined on the base station side. The comparisons conducted are used for assigning radio communication terminals to groups, with a first group being assigned those radio communication terminals which display a good reception situation during the threshold value comparison, whereas a second group is assigned all further radio communication terminals.

Abstract: Intersystem connection handover is based on transmission quality of a first radio communication system to a base station as determined by a subscriber station. If the transmission quality is lower than a threshold value, a transmission quality determination routine to a base station of the second radio communication system is triggered. The determination routine is continued until a criterion separate from the threshold is fulfilled.

Abstract: The invention relates to a method for increasing the precision during the determination of system parameters dependent on the propagation delay, e.g. for a positional determination, in a mobile communications system with emission diversity, according to which a subscriber data signal and a reference signal are assigned to a subscriber. The subscriber data signal is emitted by at least two antenna devices on the emission side, whereas the reference signal is emitted exclusively by one antenna device on the emission side. The reference signal is used to precisely determine signal propagation delays, upon which the system parameters depend.

Abstract: A method and radio communication system for synchronizing subscriber stations, wherein a time slot is assigned to a number of base stations for transmitting at least one synchronization sequence and adjacent base stations use a different time offset with respect to the beginning of the time slot for transmitting the synchronization sequence. Thus, superposition can be precluded even in the case of a synchronized operation of the base stations. So that the subscriber station can still determine the beginning of the time slot, the time offset is transmitted. The time offset corresponds to the choice of one or more synchronization sequences and/or the sequence of a number of synchronization sequences. The information relating to the time offset is transmitted coded in this manner.

The method requires only simple circuitry and little energy consumption in the mobile parts. Initial monitoring is carried out in the base station, which supports uncoordinated, unlicensed system operation.

Abstract: According to the invention, a reduced set of transport format combinations is signalled to a subscriber station which has established a link to a second radio communication system in a second signalling channel of said second radio communication system. The transport format indicator is then selected from the reduced set of transport format combinations and used to initiate a link transfer to the first signalling channel of a first radio communication system. A full set of transport format combinations is subsequently signalled to the subscriber station in the first signalling channel.

Abstract: According to the invention, transmissions of the second radio station are received in the first radio station in which the operating instruction for transmission power of the second radio station is determined. The operating instruction is transmitted during a following transmission of the first radio station to the second radio station, whereupon the latter takes into account the operating instruction for power regulation during one of its following transmissions. Contrary to prior art, no time invariable or fixed step size is used. An operating instruction is used instead which is related to a variable step size in transmission power regulation. The variable step size is subscriber-dependent and time-dependent regulated by the radio stations.

Abstract: A radio communications system provides frequency channels which are formed both by time slots and by broadband frequency ranges, and in which information from a plurality of connections is simultaneously transmitted between mobile stations and base stations wherein it is possible to distinguish the information from different connections in accordance with a connection-specific fine structure. Frequency channels are repeatedly provided for time synchronization of the mobile stations in the downward direction in which a signal form is transmitted in addition to information from further connections. The mobile station to be synchronized determines from received signals at least one instant of the arrival of the signal form, which is subsequently used by the mobile station for time synchronization. The system is advantageously applied, for example, in TDD mode for the third mobile communications generation which combines a TDMA and CDMA subscriber separation method.

Abstract: In order to control the transmitting power provided for point-to-multipoint telecommunications links in a telecommunications system with wireless telecommunication and uncoordinated unlicensed system operation, without significant restriction of the transmitting range, use is made of the fact that the maximum number of mobile stations (MS1 . . . MSn) registered in a base station (BS1) is known. Thus, the base station knows at any time how many and which mobile stations are registered. If all mobile stations are registered (NACT=NSCHED), the base station can match the transmitting power to the mobile station received as the “weakest one”. In other cases, if not all mobile stations are registered (NACT≠NSCHED), the base station will alternately transmit with the maximum transmitting.

Abstract: A mobile station, as well as a method and communication system for adapting same, is provided. The mobile station is located in a radio coverage area of a mobile radiotelephone network and generates an adaptation to a radio interface access method of the mobile radiotelephone network based on signaling information that is transmitted on a pilot channel. The pilot channel is sent by at least one broadcast transmitting station of a public broadcast system in the radio coverage area of the mobile radiotelephone network and received and evaluated by the mobile station.

Abstract: Data are transmitted through a radio interface in a GSM mobile radio system. The transmission side performs a continuous phase modulation of the transmission signals for the data to be transmitted. A bandwidth is used which is narrower than that used during a Gaussian minimum shift keying modulation with a modulation bandwidth BT equal to 0.3 so that the radio interface gives right of access on at least one channel with a reduced bandwidth. On the reception side, data detection is carried out without any discrimination between channels with different bandwidths. This enables substantially increased capacity of mobile radiotelephone networks and support for indoor and asymmetrical data transmission applications.

Abstract: A reduced set of transport format combinations is signalled to a subscriber station which has established a link to a second radio communication system in a second signalling channel of the second radio communication system. The transport format indicator is then selected from the reduced set of transport format combinations and used to initiate a link transfer to the first signalling channel of a first radio communication system. A full set of transport format combinations is subsequently signalled to the subscriber station in the first signalling channel.

Abstract: The invention relates to the transfer of intersystem connections, wherein the quality of a transfer to a supplying base station in a first radiocommunication system determined at a given moment by a subscriber station is compared to a threshold value. If the value falls below said threshold, a compressed mode is activated and measurements are carried out by the subscriber station in relation to the transfer qualities to neighbouring base stations in a second radiocommunication network. On the basis of said measurements, the subscriber station selects a base station for the transfer of a connection. If the value falls below the second threshold, information sequences in the organization channels of the selected base stations are detected by the subscriber station.
