摘要： Methods and systems are provided for using femtocells to address macro-network backhaul congestion. In an embodiment, a macro base transceiver station (BTS) that has a backhaul connection to a radio network controller (RNC) detects that a current utilization of the backhaul exceeds a backhaul-congestion threshold, and responsively identifies one or more sector-carriers having a respective current air-interface utilization that is less than a respective sector-carrier-congestion threshold for the respective sector-carrier. The macro BTS further identifies one or more femtocells that are positioned in the coverage area of the one or more identified sector-carriers, and offloads some reverse-link traffic to each identified femtocell over the forward link of an identified sector-carrier in whose coverage area the respective identified femtocell is positioned, for forwarding of the offloaded traffic by the one or more identified femtocells over a packet-data network to an intended destination.

摘要： Methods and systems are provided for using DRCLocks for conducting call admission control. In an embodiment, an access node provides service to a plurality of access terminals on a carrier in a coverage area, where the plurality of access terminals does not include a first access terminal. The access node receives a request for new service on the carrier in the coverage area from the first access terminal over an air interface, and responsively determines whether an aggregate-DRCLock condition is met. If the aggregate-DRCLock condition is met, the access node denies the request for new service.

摘要： Methods and systems are provided for implementing quality of service (QoS) by using Hybrid ARQ (HARQ) response for triggering the EV-DO reverse activity bit (RAB). In an embodiment, an access node provides service to a plurality of access terminals, the plurality including a select group of one or more access terminals. The access node detects that it has, over a time period, sent more than a threshold number of HARQ negative acknowledgements (NACKs) with respect to reverse-link communication of the select group, and responsively (1) sets the RAB for the first wireless coverage area and (2) instructs the select group of access terminals to ignore the RAB. The select group ignores the RAB, while the rest of the access terminals obey the RAB.

摘要： A method and system for a wireless communication device (WCD) to perform handover from a first BTS that serves a plurality of WCDs via a first air interface protocol (AIP) and a second BTS that serves another plurality of WCDs via a second AIP. The first BTS includes a modem for data-transfer via the second AIP, and the second BTS includes a modem for data-transfer via the first AIP. While the WCD is engaging in a communication session via the first BTS and first AIP, the modem of the first BTS transmits a handover request via the second AIP. The second BTS receives the request and responsively reserves resources for the WCD to use after handover and notifies the first BTS of the resources via the second AIP. The first BTS notifies the WCD of the resources via the first AIP and the WCD hands over to the second BTS.

摘要： Methods and systems are provided for achieving quality of service (QoS) by using the reverse activity bit (RAB) in creation of neighbor lists for selected access terminals. In an embodiment, an access node provides service to a plurality of access terminals in a first wireless coverage area. The access node maintains and broadcasts a standard neighbor list identifying neighboring wireless coverage areas, each having a respective RAB. The access node generates a QoS neighbor list, consisting of one or more coverage areas from the standard neighbor list having a RAB that is cleared. The access node transmits the QoS neighbor list to a subset of the access terminals. Each access terminal in the subset uses the QoS neighbor list in place of the standard neighbor list, while the other access terminals use the standard neighbor list.

摘要： A method and system are provided for planning a service-provider network. The service-provider network includes a macro network and a number of low-cost internet base stations (LCIBs), where the macro network includes a number of macro base transceiver stations (BTSs). One or more LCIBs are selected. The selected LCIBs are instructed to operate in an unrestricted mode and then operate in the unrestricted mode for an evaluation period. After the evaluation period ends, an off-loaded-traffic amount is determined for at least a portion of the macro network for the evaluation period. The off-loaded-traffic amount is then associated with the one or more selected LCIBs. Then, the service-provider network is planned based on the off-loaded-traffic amount.
