  • Patent number: 10660095
    Abstract: A base station dynamically controls whether or not to serve a WCD on an in-band carrier defined within occupied bandwidth of a host carrier, with the dynamic controlling being based on whether the base station is operating in a capacity-mode on the host carrier, such as whether the base station has beamforming enabled on the host carrier and/or the base station is serving one or more relay nodes on the host carrier. If the base station is operating in a capacity-mode on the host carrier, then the base station could responsively transition a WCD from being served on the in-band carrier to instead being served on a guard-band carrier defined within a guard-band of the host carrier, or to being served on another carrier that is not an in-band carrier defined in the occupied bandwidth of the host carrier.

  • Patent number: 10075851
    Abstract: A base station provides service on a host carrier, the host carrier having a host-carrier frequency range that defines a host-carrier bandwidth. Further, the base station provides service on a guest carrier concurrently with the base station providing service on the host carrier, the guest carrier having a guest-carrier frequency range that is defined fully within and as a portion of the host-carrier frequency range and that defines a guest-carrier bandwidth narrower than the host-carrier bandwidth. And the base station dynamically varies the guest-carrier bandwidth based at least on variation in quantity of client devices connected with the base station on the host carrier.

  • Patent number: 9179379
    Abstract: Disclosed is a method and apparatus and system for managing frequency use in a system where multiple air interface protocols are in use. When a wireless communication device (WCD) is operating under a particular air interface protocol on a particular frequency channel, the WCD detects a threshold signal under another air interface protocol, and the WCD responsively transitions from operating under the particular air interface protocol on the particular frequency channel to operating under the particular air interface protocol on a different frequency channel. The method may thereby help to reduce likelihood of interference.

  • Patent number: 8954083
    Abstract: A method, system, and computer-readable medium for preventing or allowing a base station (BS) to perform a particular BS function are described. The BS and/or a base station controller (BSC) determine and compare a location of the BS to respective location(s) of one or more other BSs. The BS and/or BSC determine whether the BS location is at least a threshold distance respectively from each of one or more other BSs. If the BS location is at least a threshold distance respectively from each of one or more other BSs, the BS and/or BSC sets at least one parameter to prevent the BS from performing the particular BS function. If the BS location is less than the threshold distance respectively from at least one of the one or more other BSs, the BS and/or BSC sets at least one parameter to allow the BS to perform the particular BS function.

  • Patent number: 8606219
    Abstract: A method and system for managing access probe transmission in a wireless communication system. Upon determining that an external impact event, such as a severe weather event, natural disaster, criminal activity, has occurred, base stations may wirelessly broadcast a control signal that causes certain wireless communication devices served by the base stations to suppress transmission of access probes, while allowing other wireless communication devices served by the base stations to still transmit access probes. In a given coverage area, suppression of access probe transmission by one or more wireless communication devices may thereby free up access channel capacity to facilitate calls or other communications by other wireless communication devices, such as first-responder devices for instance.

  • Patent number: 8559339
    Abstract: Methods and systems are provided for implementing a low-cost-Internet-base-station-(LCIB) user-adaptation algorithm. In an embodiment, an LCIB receives usage attempts from a plurality of mobile stations. The LCIB stores records corresponding to the usage attempts, where each record identifies the corresponding mobile station from which the corresponding usage attempt was received. The LCIB uses the records to classify each mobile station in the plurality of mobile stations as authorized or rather as unauthorized. The LCIB then configures its coverage area so as to exclude the unauthorized mobile stations.

  • Patent number: 8254330
    Abstract: Methods and systems are provided for expediting call setup in a wireless communication system. A mobile station operating in idle mode and under coverage of a first and second wireless coverage area receives overhead channel data for the first coverage area. The mobile station then detects a trigger to initiate connectivity with the wireless communication system. Responsive to detecting this trigger, the mobile station determines an amount of time until it will receive overhead channel data for the second coverage area and makes a determination of whether this determined amount of time is greater than a threshold. If the determined amount of time is greater than a threshold, the mobile station seeks connectivity via the first coverage area. However, if the determined amount of time is less than a threshold, the mobile station seeks connectivity via the second coverage area.

  • Patent number: 8208933
    Abstract: Methods and systems are provided for implementing global neighbor lists to support low-cost Internet base stations (LCIBs). In a macro wireless-communication network, each sector has a neighbor list that contains the pseudorandom number (PN) offsets of surrounding sectors. To account for LCIBs, a global neighbor list, configurable across sectors, access networks, markets, and/or vendors, is introduced. The global list may be maintained on an access network or on a separate server that interfaces with access networks. The global list may be incorporated at the beginning, in the middle (i.e. at specific priority levels), or at the end of each respective sector's neighbor list. If a given sector's neighbor list is full, it could be left unmodified, or some global-list entries could displace some existing entries. Other than incorporating entries from the global list, each macro sector's neighbor list remains, for the most part, independently modifiable.

  • Patent number: 8184598
    Abstract: Methods and systems are provided for implementing low-cost Internet-base-station (LCIB) radio-frequency (RF) adaptation using stationary transceivers. In an embodiment, an LCIB emits a pilot beacon having an adjustable transmission-power level. The LCIB repeatedly wirelessly sends transmissions for receipt by each transceiver in a set of one or more stationary transceivers while increasing the power level at which the transmissions are sent. The transceivers are arranged to wirelessly send acknowledgements to the LCIB upon successful receipt of the transmissions. The LCIB receives at least one acknowledgement from a subset of the transceivers, and responsively sets the pilot-beacon transmission-power level equal to an operating value, which the LCIB selects based at least in part on a minimum transmission-sending power level needed to receive an acknowledgement from each transceiver in the subset.

  • Patent number: 8121092
    Abstract: Methods and systems are provided for selecting a low-cost Internet base station (LCIB) for a macro-network-to-LCIB handoff of an active mobile station. In one embodiment, a handoff request is received from a mobile station, the handoff request indicating that the mobile station is requesting that a first pseudorandom number (PN) offset be added to an active set for the mobile station, the active set comprising one or more macro-network sectors. It is determined that the first PN offset is associated with an LCIB pilot beacon, and a candidate set of LCIBs is responsively identified, the candidate set consisting of substantially all of the LCIBs that are located in the one or more macro-network sectors in the active set. It is determined whether the mobile station is an authorized mobile station of exactly one LCIB in the candidate set and, if so, the mobile station is directed to handoff to that LCIB.

  • Patent number: 8059568
    Abstract: Methods and systems are provided for implementing an alternative timing source for low-cost-Internet-base-station-(LCIB) systems. In accordance with an embodiment, an LCIB has an internal clock. The LCIB is arranged to receive a GPS signal, and to treat timing information embedded in the GPS signal as the LCIB's primary source of timing information for calibrating the internal clock. The LCIB detects a loss of the GPS signal, and responsively uses a macro-network receiver to receive macro-network timing information from a macro network, which is a terrestrial wireless network. The LCIB uses the macro-network timing information to calibrate the internal clock.

  • Patent number: 8028327
    Abstract: Methods and systems are provided for a low cost Internet base station (LCIB) to grant a client device temporary access to a wireless network. In an embodiment, an LCIB receives a request from a client device. The request includes a feature code, an access code, and a client-device identifier. The feature code in the request indicates that the client device is requesting temporary access to the wireless network. Upon detecting the feature code in the request, the LCIB compares the access code in the request with a stored access code. If the access code from the request matches the stored access code, the LCIB grants the client device access to the wireless network on a temporary basis. Alternatively, if the access code from the request does not match the stored access code, the LCIB denies the client device access to the wireless network.

  • Patent number: 7974653
    Abstract: Methods and systems are provided for manually configuring low-cost Internet-base-station (LCIB) coverage using an associated mobile station. In an embodiment, an LCIB receives a user command of a first type, responsively enters a coverage-configuration mode, and then receives from a mobile station a series of user commands of a second type, each instructing the LCIB to engage in a power-calibration call with the mobile station. Responsively, the LCIB engages in a respective series of power-calibration calls with the mobile station, each call comprising the LCIB identifying a minimum transmission-power level at which a forward-link frame error rate (FFER) for the mobile station is less than a FFER threshold. The LCIB sets a transmission-power level for a pilot beacon (i.e. configures its coverage) based at least in part on the maximum transmission-power level among the minimum transmission-power levels identified while engaging in the series of power-calibration calls.

  • Patent number: 7974230
    Abstract: Methods and systems are provided for mitigating interference by low-cost Internet-base-station (LCIB) pilot beacons with macro-network communications. In one embodiment, an LCIB transmits a pilot beacon on the forward link of a carrier at a first power level. While transmitting the pilot beacon on the forward link of the first carrier, the LCIB measures a current reverse-noise rise (RNR) on the reverse link of the carrier. The LCIB determines that the current RNR is greater than an RNR threshold, and responsively transmits the pilot beacon on the carrier at a second power level, which is lower than the first power level.

  • Patent number: 7903599
    Abstract: Methods and systems are provided for mitigating interference by low-cost Internet-base-station (LCIB) pilot beacons with macro-network communications. In an embodiment, an LCIB transmits a pilot beacon having a power level that is adjustable on a per-carrier basis. The LCIB determines that it does not have any registered mobile stations, and responsively turns the power level down or off while monitoring reverse-noise rise (RNR) on one or more carriers. The LCIB then detects a threshold RNR on a carrier, and responsively carries out a sub-process a first number of times on the carrier. The sub-process comprises (a) gradually increasing the power level while continuing to monitor RNR, (b) detecting a sudden RNR decrease, and responsively turning the power level down or off while continuing to monitor RNR, and then (c) detecting an RNR increase. The LCIB waits for the RNR to return to normal before increasing the power.
