Methods and systems are provided for multi-carrier capacity increase in low-cost Internet base station (LCIB) systems by logical grouping of base stations. In an embodiment, an LCIB controller determines that a set of multiple LCIBs should be logically grouped, and selects operational parameters for each LCIB in the set. The LCIB controller designates one LCIB as a primary LCIB, thereby designating the others as secondary LCIBs. The controller configures the primary LCIB to broadcast a pilot beacon that includes at least some of the operational parameters selected for each LCIB, and to operate using the parameters selected for the primary LCIB. The controller also configures each secondary LCIB to not broadcast a pilot beacon, and to operate using the parameters selected for the respective secondary LCIB.

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.

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.

Methods and systems are provided for implementing an alternate operational-data transmission scheme for LCIB systems. According to an embodiment, an LCIB provides service to at least one mobile station on a first wireless network, the provision of service comprising (i) providing an air interface according to a first wireless technology, (ii) providing a backhaul connection over a packet-data network to a service-provider network, and (iii) bridging the air interface and the backhaul connection. The LCIB collects operational data, which the LCIB transmits to a server over a second wireless network according to a second wireless technology, where the second wireless network is different than the first wireless network, and the second wireless technology is different than the first wireless technology.

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.

Methods and systems are provided for providing wireless service using multiple protocols on a single radio-frequency (RF) carrier. According to an embodiment, a low-cost Internet base station (LCIB) provides wireless service on an RF carrier using a first wireless-communication protocol and provides wireless service on the RF carrier using a second wireless-communication protocol, where providing wireless service on the RF carrier using the first wireless-communication protocol and providing wireless service on the RF carrier using the second wireless-communication protocol occur at different times. The LCIB may alternate between providing wireless service using the first wireless-communication protocol and providing wireless service using the second wireless-communication protocol.

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.

Methods and systems are provided for prioritizing carriers in low-cost Internet-base-station-(LCIB) frequency-hopping pilot beacons. In one embodiment, an LCIB provides a frequency-hopping pilot beacon that repeatedly cycles through transmitting pilot-beacon information on each of multiple carriers. The LCIB identifies a first list of mobile stations, as well as a first list of carriers. The LCIB uses the first list of mobile stations to identify a second list of carriers from among the first list of carriers, thereby identifying a third list of carriers consisting of any carriers that are in the first list of carriers but not in the second list of carriers. The LCIB then prioritizes the second list of carriers over the third list of carriers for inclusion in the frequency-hopping pilot beacon.
摘要:
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.
