  • Patent number: 10080173
    Abstract: A method and system for controlling handover of a WCD based on the WCD's operating temperature. In an example implementation, a determination is made that the WCD's operating temperature is threshold high, and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as to another carrier frequency or to another base station coverage area. Further, in another example implementation, a determination is made that the WCD's operating temperature is threshold low (e.g., is not threshold high), and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as back to the WCD's initially serving coverage system.

  • Patent number: 10054661
    Abstract: An RF fingerprint of the environment of a base station antenna will be regularly monitored, such as by regularly evaluating various RF metrics of uplink reflections of downlink transmission from the antenna. Through regular monitoring of the RF fingerprint, a baseline RF fingerprint could be established. And through continued monitoring of the RF fingerprint, an unexpected change in the RF fingerprint could then be detected, as an indication that the antenna's RF beam direction may have changed. In response to detecting the unexpected change in the antenna's RF fingerprint, the antenna's RF beam direction could then be newly determined, and the antenna's configuration record could be updated to indicate the newly determined RF beam direction.

  • Patent number: 10015708
    Abstract: Disclosed is a method and system to help manage handover of a UE based on data buffering. In accordance with the disclosure, when a base station receives data destined for a UE, the base station may record the received data into a data buffer for temporary storage and retrieve the data at some later time to transmit the data to the UE. The base station may then determine, based at least in part on an amount of elapsed time from recording the data to retrieving the data, whether to invoke handover of the UE from being served by the base station to being served by a different, neighboring base station.

  • Patent number: 9973951
    Abstract: A method and system that uses user-equipment (UE) capability reporting to control UE service. A UE provides its serving base station with an initial capabilities report indicating that the UE does not support determining and reporting when neighboring coverage is threshold strong, and so the base station does not yet provision the UE with a measurement event including a threshold to facilitate such determining and reporting. When the UE then determines that its serving coverage is threshold weak, the UE then transmits to its serving base station an updated capabilities report indicating that the UE does support such determining and reporting, and so the base station then provisions the UE with threshold (e.g., provisions the UE with a measurement event causing the UE to compare measured neighbor coverage strength with such a threshold).

  • Patent number: 9949192
    Abstract: Disclosed are methods and systems for selection of a handover target for a user equipment device (UE). In particular, a wireless communication system may serve the UE over an air interface connection between the UE and a source base station (BS). While the system serves the UE, the system may make a selection of a handover target for the UE. And in accordance with the disclosure, the selection may be based at least in part on the handover target not having a wireless relay backhaul connection. Once the system selects the handover target using the disclosed approach, the system may then trigger handover of the UE from being served by the source BS to being served by the selected handover target.

  • Patent number: 9681411
    Abstract: A method is disclosed to help register a UE with a different network in the event of an unsuccessful registration with a fallback network. In accordance with the disclosure, a UE may be registered on a first network and may then seek to register with a second network via the first network. The first network may attempt to register the UE with the second network, but the attempt to register the UE with the second network may ultimately fail. In response to such failure, the first network may discontinue providing service to the UE. Discontinuing the providing of service to the UE on the first network may result in the UE seeking to register directly with the second network or with a different network. By registering directly with the second network, or a different network, the UE may be able to initiate and/or receive voice calls via that network.

  • Patent number: 9674809
    Abstract: A method and system for managing time segments per subframe used for downlink control channel communication by adjacent base stations that each provide carrier-aggregation service on first and second component carriers. The base stations may work with each other to differentially structure the component carriers, such that the base stations use different time segments than each other for downlink control channel communication on the first component carrier but the same time segments as each other for downlink control channel communication on the second component carrier. Further, based on this differential structuring, the base stations may then schedule transmission of one type of data on the first component carrier and another type of data on the second component carrier.

  • Patent number: 9332459
    Abstract: A method and system for setting a hold-timer duration is disclosed. The method involves a first network initially serving a user equipment device (UE), wherein serving the UE comprises allocating at least one resource to the UE and using the at least one resource to serve the UE. The method also involves detecting transition of the UE from being served by the first network to being served by a second network. The method further involves, after the UE transitions to the second network, applying a hold-timer having a hold-timer duration for release of the at least one resource. Further, the method involves, before setting the hold-timer duration, the first network receiving from the UE a report including an indication of radio frequency (RF) quality of the second network. The method also involves using the reported indication of RF quality as a basis to set the hold-timer duration.

  • Patent number: 9319988
    Abstract: A method and corresponding system to help manage user equipment device (UE) transmission power, specifically in a scenario where the UE was being served by a base station on a first carrier frequency and the UE is then going to communicate with a base station (whether the same or another base station) instead on a second, different carrier frequency. As disclosed, a UE may determine, based on communication by the UE on the first carrier frequency, a baseline initial transmit power for the UE to use for an initial transmission from the UE to a cellular base station on the second carrier frequency. Responsive to the second carrier frequency being different than the first carrier frequency, the UE may adjust the baseline initial transmit power to establish an adjusted initial transmit power. The UE may then engage in the initial transmission using the adjusted baseline initial transmit power.
