  • Patent number: 10292108
    Abstract: A method for assigning downlink transmit power levels to radio nodes (RNs) in a small cell radio access network (RAN) includes assigning initial power levels to the RNs. For each cell, first events are counted indicating that UEs receiving a signal from their serving cells with a signal strength below a specified value have entered a coverage hole. For each cell, second events are counted indicating that UEs have re-established a previous connection on one of the cells. For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.

  • Patent number: 10271373
    Abstract: A UE operating in a network that supports dual connectivity operation is configured to minimize the transmission of unnecessary UE failure indications. The UE detects secondary cell group (SCG) failure for the UE, in response to detecting one of a plurality of SCG failure-triggering events. The UE sends a UE failure indication message, in response to the detecting SCG failure, and refrains from sending further UE failure indication messages in response to SCG failure-triggering events, until the sending of further UE failure indication messages is reenabled. In some cases, the UE sets a state of the UE to a UE prohibit state to prohibit sending further UE failure indication messages while in the UE prohibit state. In other cases, the UE starts a prohibit timer to prohibit sending further UE failure indication messages during the prohibit timer.

    Abstract: Method and radio access point for handling a two-way communication between a first wireless device and a second wireless device which are both served by the radio access point. A set of candidate transmission modes are available for use in the two-way communication. The radio access point obtains a mode-specific quality metric related to a predicted Signal to Interference and Noise Ratio, SINR, for each one of the candidate transmission modes, and selects one of the candidate transmission modes based on the obtained mode-specific quality metrics. The radio access point is thus able to select the transmission mode that has the best mode-specific quality metric in the set. The selected transmission mode is then applied for the two-way communication. Thereby, the most favorable transmission mode may be selected and used to provide satisfactory or even optimal performance.

  • Patent number: 10225034
    Abstract: Mobile broadband traffic has been exploding in wireless networks (300) resulting in an increase of interferences and reduced operator control. Networks (300) are also becoming more heterogeneous putting additional demand in interference management. There is currently no support for signalling of neighbor cell interference gleaned from soft and softer handover powers. Thus, there are no algorithms that accounts for and/or estimates interference impact factors between neighboring cells based on neighbor cell interference estimates gleaned from soft and softer handover power. To address these and other issues, techniques to accurately predict/estimate neighbor cell interferences that accurately accounts for own cell powers, soft handovers, softer handovers, neighbor cell interferences, and remaining neighbor cell interferences are presented. The described techniques estimate coupling effects of scheduling decisions in one cell to surrounding cells. In this way, interferences in the network (300) can be managed.

  • Patent number: 10149172
    Abstract: Systems and methods are disclosed for networking planning for fixed backhaul networks comprising a plurality of hubs, each serving one or more RBMs. The method comprises one or more of terrain pathloss (PL) and antenna gain prediction; network design comprising site association, hub dimensioning and pointing; and optimization of small cell (SC) deployment. PL prediction is based on correlation of user input parameters with reference use cases for channel models for each of downtown, urban, and suburban deployment scenarios. Rapid and effective network planning is achieved with limited input data, even in the absence of high resolution digital maps or building polygons, by selecting the channel model having a highest correlation with available environmental parameters. Optimization of network topology design, system design, and SC deployment, with both access link and backhaul link evaluation, is based on optimization of a sum-utility function across all links for feasible SC site locations.

  • Patent number: 10142065
    Abstract: This disclosure relates to techniques for enabling a user equipment (UE) to determine which cell to attach to in a heterogeneous network (HetNet). The UE may determine, based on the quality of the downlink (DL) channel and/or on the type of traffic between the UE and a current base station, whether to attach to a small cell base station or an overlay macro base station in the cellular network. Particularly, the UE may determine whether to use a received mobility offset during cell reselection in response to a measured quality of the DL channel.

  • Patent number: 10142897
    Abstract: The present invention relates to a method and an apparatus for controlling mobility for a cell having a small cell service area in a mobile communication system. A method for controlling mobility of a terminal in a mobile communication system, according to one embodiment of the present invention, can comprise the steps of: performing, by the terminal, a measurement operation; transmitting a measurement result to a base station; determining whether or not a target cell for handover is a cell for which handover is allowed; and skipping the handover if the target cell for handover is the cell for which handover is not allowed. According to one embodiment of the present invention, when the small cells are arranged sparsely or in the form of a cluster within a service area of a macro cell, the possibility of a handover failure can be reduced, and if a radio link failure occurs when handover is omitted, re-connection can be performed quickly by the terminal.

  • Patent number: 10142462
    Abstract: Systems and methods insert a modulated signal into audio of a controlled-environment facility resident's side of a call, such as by a controlled-environment communication apparatus, or the like. The same or a different controlled-environment communication apparatus, or the like, may detect the same and/or another modulated signal inserted into the audio of the same and/or another controlled-environment facility resident's side of the call in the audio of an other party's side of the call. The same or a different controlled-environment communication apparatus, or the like, may determine if more than one modulated signal is present in the other call party's side of the call and alert an authority that more than one controlled-environment facility resident is taking part in the call.

  • Patent number: 10111117
    Abstract: A customer self-service tuning system assists a mobile device user in adjusting his network settings and device configuration. Device, network and performance metrics are stored for a population. Over time all of these suggest changes in the device or network that change measured performance. The potential improvement(s) are presented to the user for selection. Performance measurements are taken and the user can choose to go forward with the new configuration or to revert. Each time a user requests self-care service, a new cohort is extracted from the then current overall population and analyzed for similarity to the user at that point in time. Each time an improvement is selected, the history of device states and network states is augmented. Identified variances are transformed into an action plan specific to a user and implemented on the device or network upon concurrence.
