摘要:
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 dynamic selection by a mobile station of its home agent using its preferred roaming list (PRL). A mobile station maintains a PRL comprising an association between (i) a first set of data identifying a first wireless wide area network (WWAN) and (ii) a first identifier of a first home agent. The mobile station detects a broadcast of the first set of data by the first WWAN. Responsive to detecting the broadcast of the first set of data by the first WWAN, the mobile station connects to the first WWAN. Responsive to connecting to the first WWAN, the mobile station uses the first identifier to register with the first home agent.

Methods and systems are provided for identifying customers at an establishment. In an embodiment, a low-cost Internet base station (LCIB) receives a request from a mobile station to register for service with the LCIB. The LCIB is located at an establishment, such as a store. The LCIB then determines whether the mobile station is authorized to register with the LCIB. If the mobile station is authorized to register with the LCIB, the LCIB allows the mobile station to register. If the mobile station is not authorized to register with the LCIB, the LCIB or LCIB controller responsively (a) rejects the registration request and (b) sends a notification message to the establishment, the notification message identifying the mobile station.

Methods and systems are provided for dynamic adjustment of forward-link traffic-channel power levels based on forward-link RF conditions. In an exemplary embodiment, a base station provides service on a carrier in a wireless coverage area. The base station computes an Ec/Ior value for the carrier. Based at least in part on the computed Ec/Ior value, the base station adjusts at least one of an initial traffic-channel power level, a minimum traffic-channel power level, and a maximum traffic-channel power level for the carrier. As an example, if Ec/Ior is above a certain threshold, the base station may increase all three of the power levels, so as to improve service quality and coverage of its traffic channels, among other advantages.

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 dynamic adjustment of the reverse-link frame-error-rate (RFER) target based on reverse-link RF conditions. In an embodiment, a base station provides service to at least one mobile station on a carrier in a wireless coverage area using a first RFER target. The base station calculates a reverse noise rise (RNR) value for the carrier, and then selects a second RFER target based at least in part on the calculated RNR value. The base station then provides service to at least one mobile station on the carrier in the wireless coverage area using the second RFER target.
摘要:
A mobile station is associated with a first wireless coverage area that has a first pilot signal. A second wireless coverage area that has a second pilot signal is in the mobile station's neighbor list. The mobile station measures E1, the energy per chip of the first pilot signal, and I1, the total received power at the first pilot's frequency. The mobile station also measures E2, the energy per chip of the second pilot signal, and I2, the total received power at the second pilot's frequency. If E2 exceeds E1 by at least a first predetermined amount and E2/I2 exceeds E1/I1 by at least a second predetermined amount, then a handoff of the mobile station from the first wireless coverage area to the second wireless coverage area is effected.

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.
摘要:
Methods and systems are provided for dynamic determination of EV-DO control-channel bit rate based on forward-link timeslot utilization. Service is provided to access terminals on a carrier in a wireless coverage area. The carrier comprises timeslots that can be active or idle. Active timeslots comprise a data channel; idle timeslots do not. The data channel is arranged to transmit user-traffic information, and also to transmit control-channel information at a bit rate that can be set to a first or second value, where the second value is greater than the first value. A number of active timeslots on the carrier in the coverage area over a time period is determined. It is further determined whether that number is less than a threshold number. If so, the bit rate is set to the first value; if not, the bit rate is set to the second value.
