A first base station associated with a first radio cell is used to transmit data packets in a second sequence to at least one subscriber station by at least one first radio channel. The subscriber station sorts out the received data packets into a first sequence in an intermediate storage unit and the base station associated with the first radio cell is used to derive and/or represent status information relating to the content of the intermediate storage unit in a status memory unit. Transmission of the data packets is relayed from the first to the second radio cell and data packets are transmitted by a base station associated with the second radio cell to the subscriber station by at least one other radio channel. The status information is transferred from the base station associated with the first radio cell to the base station associated with the second radio cell.

Method for transmitting packet switched data in a cellular radio communicaton system during cell change

A method and radio communication system for the transmit useful information as a service to several user stations with at least one radio network controller, at least one base station and at least one user station. The radio network controller is connected to an access device in a core network. The useful information is provided to several users as a service, whereby the user stations of the users are informed before the transmission of the useful information. According to the invention, the notification for the user stations of the users at least partly comprises a request for a response and the transmission of the useful information at least partly occurs after receipt of the response.

Method and radio communication system for the transmission of useful information as a service to several user stations

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.

Wireless communication after subscriber station is switched on

According to a first aspect, there is provided a method for controlling uplink access transmissions in a radio communication system, wherein a user equipment determines a delay time for transmitting a signal on an uplink access channel, wherein the delay time is randomly determined based upon a probability distribution that increases in density with increasing delay. According to a second aspect, there is provided a method for controlling uplink access transmissions in a radio communication system, wherein from a base station of the radio communication system, time variable information is signalled in downlink to user equipments located in an area covered by the base station, wherein the information is used to determine delay times for transmitting signals on an uplink access channel and wherein the information varies based upon a probability distribution which increases in density with increasing time.

Method for uplink access transmissions in a radio communication system

A method for packet-switched transmission of data. A first base station associated with a first radio cell is used to at least partially transmit data packets in a second sequence to at least one subscriber station by at least one first radio channel. The at least one subscriber station sorts out the received data packets into a first sequence in an intermediate storage unit and the base station associated with the first radio cell is used to derive and/or represent status information relating to the content of the intermediate storage unit in a status memory unit. Transmission of the data packets is relayed from the first to the second radio cell and data packets are transmitted by a base station associated with the second radio cell to the at least one subscriber station by at least one other radio channel. The status information is transferred from the base station associated with the first radio cell to the base station associated with the second radio cell.

Method for transmitting packet switched data in a cellular radio communication system during cell change

At least one request between neighboring access nodes in a radio communications system is transmitted after verifying a class of the at least one request being transmitted between the neighboring access nodes, where the class assigned by an access node indicates a priority of the request. Based upon the verified class, the transmission of the request is controlled.

Method for controlling transmissions between neighboring nodes in radio communications system and access node thereof

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).

Method for the transmission of data packets in a radio communication system based on high and low priority

The transmission of data is controlled in a radio communication system having a hierarchical network structure. A low-hierarchy device transmits load-based signalling to a high-hierarchy device and the high-hierarchy device caries out control of the transmission capacities of the low-hierarchy device based on the load-based signalling.

Method for controlling data transmission in a radio communication system with a hierarchical network architecture

A method transmits data packets in a radio-communication system. A criterion is associated with a data packet received by a radio station, and a data packet which is correctly received is transmitted to another device and/or protocol layer when the criterion has been met.

Method and radio sation for transmitting data packets in a radio-communication system

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.
