  • Patent number: 9888400
    Abstract: A method in a radio network node is disclosed for handling positioning data in a radio communications network, which radio network node serves a user equipment in a cell. The radio network node obtains positioning data from the user equipment, which positioning data is associated with a positioning measurement for positioning the user equipment. The radio network node associates the obtained positioning data with an on-going trace session of the user equipment. The radio network node then sends a trace record to a network management node, which trace record includes information associated with the positioning data.

  • Publication number: 20180031388
    Abstract: Techniques of altitude determination by user equipment (UE) in a mobile communications network are discussed. A request for calibration data is transmitted to a node of the network. Barometric calibration data is received at the UE. A barometric pressure sensor in the UE measures a barometric pressure value based on the barometric calibration data. Measuring the barometric pressure value using the barometric pressure sensor in an embodiment comprises adjusting a measured barometric pressure value that is measured using the barometric pressure sensor. The barometric pressure value is transmitted to the node. The UE receives a second part of the barometric calibration data, and in dependence of the second part of the barometric calibration data and/or in dependence of the measured barometric pressure value, determines an altitude of the user equipment.

  • Patent number: 9866355
    Abstract: Methods, arrangement and network nodes for supporting inter-cell coordination of scheduling of radio resources subjected to inter cell interference. The methods involve identifying one or more radio resources which are subjected to inter-cell interference between a first cell and a second cell. The methods further involve deriving a respective service value related to service that could be provided in the respective first and second cell by use of the one or more radio resources. Further, transmissions in the one or more radio resources are controlled based on comparison of the service values, thus enabling inter-cell service value-based scheduling of the one or more radio resources, prioritizing services having the highest value per radio resource.

  • Patent number: 9832731
    Abstract: The present invention relates to methods and arrangements in a wireless communication system, and in particular to uplink outer loop power control. A Node B identifies if a UE from which the Node B receives data is in a predetermined set of power challenged situations. The Node B transmits to the RNC an indication to hold the SIR target of the UE if the UE has been identified to be in a power challenged situation. As a consequence, the uplink outer loop power control (OLPC) procedure in the RNC will not change the SIR target of the UE. This implies that the output power level of the UE remains unchanged as long as the UE remains in the power challenged situation. Thus, user and network performance are improved in the wireless communication system.

  • Publication number: 20170318508
    Abstract: Small base station, micro, femto or pico BTS (PBS) are connected via Un interface to a donor eNB DeNB. In case of a handover from that PBS packets that had not been acknowledged by a UE need to be forwarded to the target base station. Forwarding them via Un and DeNB to the target eNB causes latency and wast radio resources on Un. Thus, the DeNB uses information about the handover to buffer packets and, after being informed by PBS, forward those packets that had not been acknowledged by the UE. This procedure, therefore, saves resources on Un interface and reduces latency. No forwarding of those packets from PBS to DeNB is required. There is provided a method for forwarding data to a wireless terminal. The method is performed by a proxy node. The method comprises receiving data on a link between a core network and a backhaul hub node. The data is addressed to a wireless terminal served by, or handed over from, a serving network node.

  • Patent number: 9807660
    Abstract: The present disclosure relates to facilitating load sharing between a serving cell and a neighboring cell of a cellular radio communication system. The serving cell serves a plurality of radio devices. A network node of the cellular radio communication system defines a first group of radio devices. The first group is a sub-group of the plurality of radio devices served by the serving cell. The network node associates the first group of radio devices with a load sharing boundary to a load sharing zone between the serving cell and the neighboring cell. Beyond the load sharing boundary, the radio devices in the first group are regarded as being able to be handed over to the neighboring cell. The network node gathers statistics relating to connection failures experienced by the radio devices in the first group and adjusts the load sharing boundary based on the gathered statistics.
