Abstract: A measuring device for testing mobile-radio relay stations provides at least one antenna and a processing unit. A base station or a mobile station transmits a first signal to a relay station. The relay station generates a second signal derived from the first signal and transmits it. The antenna of the measuring device receives the first signal and the second signal. The processing unit of the measuring device compares the received signals.

Abstract: A radio communication network having at least two base stations. The base stations communicate with mobile stations using time slots. The time slots are divided into transmission slots, during which the base stations transmit messages, and receiving slots, during which the base stations receive messages. The base stations jointly determine an assignment of the time slots as transmission slots and receiving slots.

Abstract: A method for improved determination of the position of a user device in a mobile-radio network is provided. In combination with adjacent, second user devices, the method is intended to achieve a relatively-accurate positioning even if only a relatively-inaccurate positioning method is available for the user device itself, especially if the latter is disposed inside a building. An absolute position of a second user device is determined with a first position-determining method. A relative position of the first user device relative to the second user device is then determined with a second position-determining method. Finally, the absolute position of the first user device is determined on the basis of the absolute position of the second user device and the relative position of the first user device relative to the second user device, wherein the first and the second position-determining methods are different methods.

Abstract: A measuring system is used for testing a feedback signal transmitted by a communications device within a communications system. The measuring system comprises an antenna system and a measuring device. The measuring device transmits a signal to a communications device via the air interface and the antenna system. The communications device receives the signal and generates a feedback signal dependent upon transmission conditions of the signal, which it has determined, and transmits it to the measuring device. The measuring device measures the actual reception quality of the signal in the communications device.

Abstract: In a radio communication system including a plurality of subscriber stations and at least one radio access device, useful information of a group of subscriber stations is transmitted by radio. A number of subscriber stations of the group is located in the radio coverage area of the at least one radio access device. The at least one radio access device notifies the subscriber stations of the number of subscriber stations of the group before the useful information is transmitted, using a radio resource. The notification contains information relating to at least one signal in the transmission of the useful information transmitted via another radio resource.

Abstract: Disclosed is a method for the transmission of data packets in a radio communication system, wherein the transmission of data packets of a data flow having a first priority (Prio) with respect to the transmission of data packets is interrupted by that of a second priority (Prio) if the second priority (Prio) is higher than the first priority (Prio).

Abstract: A radio communication network having at least two base stations. The base stations communicate with mobile stations using time slots. The time slots are divided into transmission slots, during which the base stations transmit messages, and receiving slots, during which the base stations receive messages. The base stations jointly determine an assignment of the time slots as transmission slots and receiving slots.

Abstract: A base station of a mobile communication network is connected to a core network and is operable in a normal mode and in a direct mode. The base station detects a request originating from a first user equipment to communicate with a second user equipment. The first user equipment is in direct reach of the base station. The base station establishes a communication link between the first and the second user equipment, and checks if the second user equipment is also within direct reach of the base station. The base station operates the communication link in direct mode, if yes, and operates the communication link in normal mode, otherwise.

Abstract: A method is provided for the administration of a muticast service whereby mobile terminals of users who have subscribed to the multicast service receive multicast messages via a mobile communication network. The present invention seeks to use the available radio resources in a more economical manner. To this end, the mobile terminals are respectively prodied with an input unit which, when actuated, produces activation information which indicates whether the multicast service is activated or deactivated, and the activation information is transmitted to the mobile communication network.

Abstract: A data service is provided in which a network-side radio station emits data, which can be received by at least one subscriber's station without a logical connection being set up between the subscriber's station and the network-side radio station. Radio parameters for emitting the data are set according to features of subscriber's stations located within an area assigned to the network-side radio station. The network-side radio station obtains the items of information concerning the subscriber's station located within the area and items of information concerning the features of these subscriber's stations, in particular, from a higher-ranking network unit.

The received data packets are stored in coded or uncoded form in the receiver inside a memory. The receiver notifies the transmitter of the capacity utilization of the memory.

Abstract: A radiocommunication system has a downward link radio channel associated with each upward link radio channel, respectively. A subscriber station receives data from a radio station on a network side to the downward link radio channel, with no logic liaison being established between the subscriber station and the radio station on the network side. A message is sent by the subscriber station on the upward link radio channel associated with the downward link radio channel. Said message is emitted by the radio station on the network side via the downward link radio station.
