Abstract: An object of the present invention is to provide a mechanism for an improved network capacity when using fixed wireless terminal. The object is achieved by a method in a radio access network node for establishing at least two packet data tunnels for packet transmission, from a fixed wireless terminal in a local area network through a set of cells in a radio access network. The set of cells comprises at least two cells. The fixed wireless terminal is a radio access network node comprised in the radio access network. The radio access network comprises a plurality of potential cells to which the packet data tunnels may be established, whereof said set of cells are part of the potential cells. The method comprising the steps of: Selecting the set of cells to use for a packet transmission, based on radio link quality between the fixed wireless terminal and each of the respective potential cells and establishing the at least two packet data tunnels, one individual packet data tunnel from the fixed wireless terminal through each of the respective cells in the selected set of cells.

Abstract: In a telecommunication system that generates more than one type of communication data stream, in which each data stream exhibits a distinctive data transfer format, bandwidth utilization is improved by first reformatting the different data tansfer formats so that all of the data is compatible with a common data transfer protocol, for example, the Asynchronous Transfer Mode (ATM) protocol. The communication data and the corresponding control data, required to maintain communication data alignment, are multiplexed into a single data stream which is then transmitted over a common telecommunication channel to a receiving station.

Abstract: The method to indicate the size of a mini cell in a mobile telephone communications system involves providing a cell size indicator in the header of the mini cell. The cell length indicator is a short fixed length field which is non-linearly coded. Preferably, the cell size indicator includes an extension bit provided in the fixed size length field. The extension bit, if set, indicates that a further fixed size length field follows the fixed size length field in the header. The length indicator includes a predefined code which, if present, indicates that a further fixed size length field follows the fixed size length field in the header.

Abstract: The present invention relates to a method and an arrangement for synchronising communication of framed data via asynchronous base stations (BS1, BS2) in a cellular communications system, e.g. a CDMA-system. The synchronisation method is performed continuously by sending out certain system frame counter states from a central node in the system to all its connected base stations (BS1, BS2). Each base station (BS1, BS2) comprises a local frame counter (LFCBS1; LFCBS2), which generates local frame counter states (t1(1)-t1(4); t2(1)-t2(4)) correlated to the system frame counter states. Transmission of information via the base stations (BS1, BS2) is synchronised by assigning each data frame (DF(1)-DF(4)) a particular frame number, which is given by the local frame counter states (t1(1)-t1(4); t2(1)-t2(4)), so that data frames (DF(1)-DF(4)) having identical numbers are contain copies of a certain data packet. Correct frame numbers are derived from common downlink channel offset measurements (CCO1; CCO2) carried out in the base stations (BS1, BS2), and timing advance values (TA2) and downlink channel offsets (DCO1; DCO2) calculated in the central node.

Abstract: In a mobile communication system (T1) a time interval selection means (TIFM) in a network control means (RNC) determines a time interval and sends an indication about this time interval to a subscriber station (MS) in a time interval indication signal. A time interval signal determining means (TIFDM) in the subscriber station (MS) detects the time interval and an IF measurement means (IFMM) carries out inter-frequency/inter-system measurements in the detected time interval specified by the network control means (RNC). In this time interval the temporary reduction of the quality of service QoS on the communication connection (CC) is planed by the network control means (RNC). However, independent as to whether a delay-sensitive or loss-sensitive data transmission is carried out, the network control means (RNC) can make provisions in order to compensate the temporary reduction of the quality of service. Such procedure is superior to performing IF measurements in an idle time interval of a compressed time slot in which a temporary degradation of the quality of service must always be accepted due to a compressed mode of operation.
