  • Patent number: 9215638
    Abstract: Disclosed are systems and methods for regulating system reselections by idle-mode mobile devices. In one aspect, a femtocell may be configured to reduce frequency of its reselection beacon, which reduces probability that a fast moving mobile device will detect the reselection beacon and reselect to that femtocell. This aspect may also delay femtocell reselection for slow moving mobile devices. In another aspect, a macrocell may slow down system reselection by adjusting cell reselection parameters used by mobile devices to determine the time needed to evaluate cell reselection criteria. Yet in another aspect, a macrocell may instruct a collocated femtocell to decrease its effective coverage area to avoid premature reselection by fast moving mobile devices. Yet in another aspect, a femtocell may use power boosting techniques to increase its reselection radius.

  • Patent number: 9185619
    Abstract: Methods and apparatuses are provided for mitigating interference among access points, and/or devices communicating therewith, in unplanned network deployments. Based on determining that one or more served devices potentially interfere with one or more access points, an inter-frequency handover (IFHO) threshold or data rate can be adjusted for the device to cause IFHO or reduce occurrence of interference, and/or a coverage area can be modified so the device can communicate with one or more other access points to mitigate potential interference. Based on determining interference from one or more devices served by other access points, an access point can switch operating modes to a hybrid or open access point to allow the one or more devices to handover to the access point, and/or can boost downlink transmit power to cause the one or more devices to perform IFHO from the other access points to mitigate potential interference.
