  • Patent number: 8154991
    Abstract: The present invention relates to an arrangement comprising an Ethernet carrier network, managed by a management system (100) and comprising a number of levels of management domains, each comprising a number of edge nodes (10, 20, 30, 40) and a number of intermediate nodes (1, 2, 3, 4, 5, 6, 7, 8). Each edge node (10, 20, 30, 40) comprises fault detection of connectivity check messages and fault locating means with holding means (11, 21, 31, 41) adapted to hold path information for the paths to all other edge nodes. A fault detection means of an edge node having detected a fault is adapted to activate edge node fault locating means to locate the fault using the patch information in the edge node holding means to find a first target intermediate node substantially in the middle of the path containing the fault, and to, directly, send a first loop back message to said intermediate node.

  • Patent number: 8155651
    Abstract: A user equipment (UE) includes a resettable timer that clocks a period after a successful packet-switched handover in a communication system. If a command message for setting packet-data transmission parameters is not received from the network before the period elapses, the UE starts a transmission-parameter negotiation if the UE wishes to do so. In this way, a UE can negotiate optimal parameters for packet-data transmission.

  • Patent number: 8155065
    Abstract: The present invention relates to methods and arrangements for interference reduction for bursty or intermitted transmissions. DPCCH gating with regular on/off-gating patterns can create waveforms that can interfere with non-UMTS audio equipments, e.g. hearing aids. The present invention relates to modifying the transmission instants of data packets in such a way such interference can be significantly reduced. This is achieved by introducing a randomization mechanism into the mapping function of data packets onto the HARQ processes, which in turn are mapped onto predefined transmission occasions (sub-frames). This results in a non-periodic transmission pattern while maintaining user data transmission requirements.

  • Patent number: 8152736
    Abstract: A device (6) to sample molecules of biological interest is described. The device (6) includes capture zones (10) whose developed surface area is much greater than the surface so that sampling by contact allows a sufficient quantity of molecules to be obtained to achieve reliable analysis, whilst being sized so that the device (6) is neither invasive nor aggressive. In particular, the device comprises tiered capture zones (10) located on a support (12) fabricated using microtechnology techniques; the capture zones (10) may advantageously be functionalised.

  • Patent number: 8155083
    Abstract: A technique of configuring link layer entities for a handover is described. In a method embodiment, the technique includes receiving from a recipient of protocol data units a supplemental status report for an existing ARQ connection in context with an imminent handover, determining service data units corresponding to buffered protocol data units taking into account information included in the supplemental report, and transferring the determined service data units to a link layer entity which is to establish a new ARQ connection to the recipient. The forced status synchronization that is based on the supplemental report prevents the transfer of service data units that have already been successfully received at the recipient.

  • Patent number: 8155030
    Abstract: There is disclosed a manner of managing the active topology, that is the scheme for forwarding data, in a computer network such as an Ethernet local area network. A root bridge is selected from a plurality of bridges in the network; the root bridge calculating at least one spanning tree from a topology database that has been populated by bridge neighbor information gleaned from link state advertising messages. The root bridge may also calculate an alternate topology for implementation in the event a failure condition that affects the primary spanning tree is detected. The root bridge then advertises the spanning tree and remotely configures the port states of the bridges in the spanning tree through tree advertising messages that the bridges are arranged to process and set their ports accordingly.

  • Publication number: 20120083300
    Abstract: The present invention relates to a centralised power allocation method in a wireless telecommunication system comprising at least a first couple of terminals, consisting of a first transmitting terminal and a first receiving terminal, and a second couple of terminals, consisting of a second transmitting terminal and a second receiving terminal. A control node partitions the interference diagram between the communication of the first couple and the communication of the second couple, into different areas, each area being associated to a type of processing of the interference. The control node calculates the minimum power curve for each communication in each said area. The power values to be allocated are given by the coordinates of the point of intersection of both curves in said diagram.

    Abstract: A method in a switching node of a circuit-switched telecommunications network comprises the steps of receiving from a packet-switched telecommunications network a request to establish a call towards a mobile station of the circuit-switched telecommunications network, and sending a request message to a location register for an instruction comprising one or more parameters for allowing the continuation of the establishment of the call to the mobile station. Upon receiving the one or more parameters from the location register, at least one of the one or more parameters is used to establish the call towards the mobile station. Furthermore, at least one of the one or more parameters is sent to the packet-switched telecommunications network. The at least one or more parameters sent to the packet-switched telecommunications network relates to the location of the mobile station. Therefore, entities within a packet-switched telecommunications network (e.g.
