  • Patent number: 9451509
    Abstract: Disclosed herein are an apparatus for providing handover information within a femtocell network, and a terminal using the same. The apparatus includes an expected stay time calculation unit, a handover target selection unit, and a handover information provision unit. The expected stay time calculation unit, for a terminal located within serving coverage range of a serving base station, calculates expected stay time, that is, a time for which the terminal will stay within a femtocell coverage range of each of the femtocell base stations. The handover target selection unit selects a handover target from among the femtocell base stations based on the calculated expected stay time. The handover information provision unit provides the terminal with handover information including the selected handover target.

  • Patent number: 9439206
    Abstract: A method is provided for controlling measurements in a wireless telecommunications terminal. In a Long Term Evolution (LTE) wireless communication system, the network instructs a UE to measure the received power and quality of the reference signals of the serving cell as well as of neighbor cells. The object of improving the system power consumption of user equipment (UE) that has to perform such measurements is solved by distributing the measurement functionality between RRC and PHY layers such that the RRC layer is enabled to rest in a power save mode unless results of the measurements have to be reported to the network, and to be only active for a minimum to ensure that the UE still behaves standard compliant to the network.

  • Patent number: 9420627
    Abstract: Systems, methods, and device for adjusting an operation time of a radio link failure timer are disclosed herein. User equipment (UE) may be configured to communicatively couple to an evolved Universal Terrestrial Radio Access Network (E-UTRAN). The UE use different radio link failure timer parameters depending on the speed of the UE. The radio link failure timer may run for a longer time for rapidly moving UEs and run for a shorter time for slowly moving UEs. In an embodiment, the UE may scale the radio link failure timer by a scaling factor. In another embodiment, the UE may include multiple radio link failure timers for different speeds. The radio link failure timer parameters for each speed may be specified by the E-UTRAN in a one-to-one communication. The E-UTRAN may determine which parameters to use for each UE based on characteristics of the UE.

  • Patent number: 9414288
    Abstract: A mobile wireless communication device notifies communication infrastructure that the mobile wireless communication device is traveling at a speed greater than a threshold speed. In response, the network infrastructure instructs the mobile wireless communication device to use a transition procedure to transition between base stations where the transition procedure is different from a handover procedure used by the mobile wireless communication device to change base stations when the speed of the mobile wireless communication device is less than or equal to the threshold speed.

  • Patent number: 9392599
    Abstract: A communication system improving the communication quality in a case where a plurality of communication devices having different sizes of ranges coexist, in which communication with a terminal device is possible, to thereby improve an entire throughput. In a case where a remote radio head (RRH) is installed in a coverage of a macro cell, an uplink resource transmitted from a user equipment (UE) to the macro cell, that is, an uplink carrier frequency band UL1 of the macro cell is received not only by the macro cell but also by the RRH. Then, the macro cell combines a reception signal regarding the uplink resource of the macro cell, which has been received by the macro cell, and a reception signal regarding the uplink resource of the macro cell, which has been received by the RRH.

  • Patent number: 9344898
    Abstract: Base station capable of suppressing interference of a large cell having high transmission power with a small cell having low transmission power and wherein frequency block division loss is low. Macrocell base station has: a frequency resource information generation unit, which calculates average value of allocated frequency resources, determines the calculated frequency resource average value on the basis of a resource allocation recurrence threshold, and generates frequency resource information from the result of the determination; an information control unit which notifies the frequency resource information to a femtocell; and first and second signal generation units which generate and output first report information which is cell information normally sent to a wireless communication terminal, and second report information which limits area that can be notified.

  • Patent number: 9338723
    Abstract: A device is configured to establish a session with a mobile device. The session may allow the mobile device to communicate with or via an operator network via the device. The device may determine a speed at which the mobile device is traveling. The device may determine a cell type for a neighbor base station. The cell type may indicate a type of cell that the neighbor base station services. The device may selectively hand over the session to the neighbor base station based on the speed at which the mobile device is traveling and the cell type for the neighbor base station.

  • Patent number: 9307518
    Abstract: Methods and apparatuses are provided for performing communication by a UE in a mobile communication system. A speed of the UE is measured by using an acceleration sensor in the UE. The UE determines that a change of the measured speed is detected in accordance with a predetermined criteria. The UE transmits information about the measured speed to a serving base station if the change of the measured speed is detected. Information about a target cell determined by the serving base station based on the measured speed is received from the serving base station. A handover procedure to the target cell is performed in response to receiving the information about the target cell.
